Merge tag 'perf-urgent-2020-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner:
"A set of fixes and improvements for the perf subsystem:
Kernel fixes:
- Install cgroup events to the correct CPU context to prevent a
potential list double add
- Prevent an integer underflow in the perf mlock accounting
- Add a missing prototype for arch_perf_update_userpage()
Tooling:
- Add a missing unlock in the error path of maps__insert() in perf
maps.
- Fix the build with the latest libbfd
- Fix the perf parser so it does not delete parse event terms, which
caused a regression for using perf with the ARM CoreSight as the
sink configuration was missing due to the deletion.
- Fix the double free in the perf CPU map merging test case
- Add the missing ustring support for the perf probe command"

+==================
+Boot Configuration
+==================
+
+:Author: Masami Hiramatsu <mhiramat@kernel.org>
+
+Overview
+========
+
+The boot configuration expands the current kernel command line to support
+additional key-value data when booting the kernel in an efficient way.
+This allows administrators to pass a structured-Key config file.
+
+Config File Syntax
+==================
+
+The boot config syntax is a simple structured key-value. Each key consists
+of dot-connected-words, and key and value are connected by ``=``. The value
+has to be terminated by semi-colon (``;``) or newline (``\n``).
+For array value, array entries are separated by comma (``,``). ::
+
+KEY[.WORD[...]] = VALUE[, VALUE2[...]][;]
+
+Unlike the kernel command line syntax, spaces are OK around the comma and ``=``.
+
+Each key word must contain only alphabets, numbers, dash (``-``) or underscore
+(``_``). And each value only contains printable characters or spaces except
+for delimiters such as semi-colon (``;``), new-line (``\n``), comma (``,``),
+hash (``#``) and closing brace (``}``).
+
+If you want to use those delimiters in a value, you can use either double-
+quotes (``"VALUE"``) or single-quotes (``'VALUE'``) to quote it. Note that
+you can not escape these quotes.
+
+There can be a key which doesn't have value or has an empty value. Those keys
+are used for checking if the key exists or not (like a boolean).
+
+Key-Value Syntax
+----------------
+
+The boot config file syntax allows user to merge partially same word keys
+by brace. For example::
+
+ foo.bar.baz = value1
+ foo.bar.qux.quux = value2
+
+These can be written also in::
+
+ foo.bar {
+ baz = value1
+ qux.quux = value2
+ }
+
+Or more shorter, written as following::
+
+ foo.bar { baz = value1; qux.quux = value2 }
+
+In both styles, same key words are automatically merged when parsing it
+at boot time. So you can append similar trees or key-values.
+
+Comments
+--------
+
+The config syntax accepts shell-script style comments. The comments starting
+with hash ("#") until newline ("\n") will be ignored.
+
+::
+
+ # comment line
+ foo = value # value is set to foo.
+ bar = 1, # 1st element
+ 2, # 2nd element
+ 3 # 3rd element
+
+This is parsed as below::
+
+ foo = value
+ bar = 1, 2, 3
+
+Note that you can not put a comment between value and delimiter(``,`` or
+``;``). This means following config has a syntax error ::
+
+ key = 1 # comment
+ ,2
+
+
+/proc/bootconfig
+================
+
+/proc/bootconfig is a user-space interface of the boot config.
+Unlike /proc/cmdline, this file shows the key-value style list.
+Each key-value pair is shown in each line with following style::
+
+ KEY[.WORDS...] = "[VALUE]"[,"VALUE2"...]
+
+
+Boot Kernel With a Boot Config
+==============================
+
+Since the boot configuration file is loaded with initrd, it will be added
+to the end of the initrd (initramfs) image file. The Linux kernel decodes
+the last part of the initrd image in memory to get the boot configuration
+data.
+Because of this "piggyback" method, there is no need to change or
+update the boot loader and the kernel image itself.
+
+To do this operation, Linux kernel provides "bootconfig" command under
+tools/bootconfig, which allows admin to apply or delete the config file
+to/from initrd image. You can build it by the following command::
+
+ # make -C tools/bootconfig
+
+To add your boot config file to initrd image, run bootconfig as below
+(Old data is removed automatically if exists)::
+
+ # tools/bootconfig/bootconfig -a your-config /boot/initrd.img-X.Y.Z
+
+To remove the config from the image, you can use -d option as below::
+
+ # tools/bootconfig/bootconfig -d /boot/initrd.img-X.Y.Z
+
+Then add "bootconfig" on the normal kernel command line to tell the
+kernel to look for the bootconfig at the end of the initrd file.
+
+Config File Limitation
+======================
+
+Currently the maximum config size size is 32KB and the total key-words (not
+key-value entries) must be under 1024 nodes.
+Note: this is not the number of entries but nodes, an entry must consume
+more than 2 nodes (a key-word and a value). So theoretically, it will be
+up to 512 key-value pairs. If keys contains 3 words in average, it can
+contain 256 key-value pairs. In most cases, the number of config items
+will be under 100 entries and smaller than 8KB, so it would be enough.
+If the node number exceeds 1024, parser returns an error even if the file
+size is smaller than 32KB.
+Anyway, since bootconfig command verifies it when appending a boot config
+to initrd image, user can notice it before boot.
+
+
+Bootconfig APIs
+===============
+
+User can query or loop on key-value pairs, also it is possible to find
+a root (prefix) key node and find key-values under that node.
+
+If you have a key string, you can query the value directly with the key
+using xbc_find_value(). If you want to know what keys exist in the boot
+config, you can use xbc_for_each_key_value() to iterate key-value pairs.
+Note that you need to use xbc_array_for_each_value() for accessing
+each array's value, e.g.::
+
+ vnode = NULL;
+ xbc_find_value("key.word", &vnode);
+ if (vnode && xbc_node_is_array(vnode))
+ xbc_array_for_each_value(vnode, value) {
+ printk("%s ", value);
+ }
+
+If you want to focus on keys which have a prefix string, you can use
+xbc_find_node() to find a node by the prefix string, and iterate
+keys under the prefix node with xbc_node_for_each_key_value().
+
+But the most typical usage is to get the named value under prefix
+or get the named array under prefix as below::
+
+ root = xbc_find_node("key.prefix");
+ value = xbc_node_find_value(root, "option", &vnode);
+ ...
+ xbc_node_for_each_array_value(root, "array-option", value, anode) {
+ ...
+ }
+
+This accesses a value of "key.prefix.option" and an array of
+"key.prefix.array-option".
+
+Locking is not needed, since after initialization, the config becomes
+read-only. All data and keys must be copied if you need to modify it.

+===================
+NFS Fault Injection
+===================
+
+Fault injection is a method for forcing errors that may not normally occur, or
+may be difficult to reproduce. Forcing these errors in a controlled environment
+can help the developer find and fix bugs before their code is shipped in a
+production system. Injecting an error on the Linux NFS server will allow us to
+observe how the client reacts and if it manages to recover its state correctly.
+
+NFSD_FAULT_INJECTION must be selected when configuring the kernel to use this
+feature.
+
+
+Using Fault Injection
+=====================
+On the client, mount the fault injection server through NFS v4.0+ and do some
+work over NFS (open files, take locks, ...).
+
+On the server, mount the debugfs filesystem to <debug_dir> and ls
+<debug_dir>/nfsd. This will show a list of files that will be used for
+injecting faults on the NFS server. As root, write a number n to the file
+corresponding to the action you want the server to take. The server will then
+process the first n items it finds. So if you want to forget 5 locks, echo '5'
+to <debug_dir>/nfsd/forget_locks. A value of 0 will tell the server to forget
+all corresponding items. A log message will be created containing the number
+of items forgotten (check dmesg).
+
+Go back to work on the client and check if the client recovered from the error
+correctly.
+
+
+Available Faults
+================
+forget_clients:
+ The NFS server keeps a list of clients that have placed a mount call. If
+ this list is cleared, the server will have no knowledge of who the client
+ is, forcing the client to reauthenticate with the server.
+
+forget_openowners:
+ The NFS server keeps a list of what files are currently opened and who
+ they were opened by. Clearing this list will force the client to reopen
+ its files.
+
+forget_locks:
+ The NFS server keeps a list of what files are currently locked in the VFS.
+ Clearing this list will force the client to reclaim its locks (files are
+ unlocked through the VFS as they are cleared from this list).
+
+forget_delegations:
+ A delegation is used to assure the client that a file, or part of a file,
+ has not changed since the delegation was awarded. Clearing this list will
+ force the client to reacquire its delegation before accessing the file
+ again.
+
+recall_delegations:
+ Delegations can be recalled by the server when another client attempts to
+ access a file. This test will notify the client that its delegation has
+ been revoked, forcing the client to reacquire the delegation before using
+ the file again.
+
+
+tools/nfs/inject_faults.sh script
+=================================
+This script has been created to ease the fault injection process. This script
+will detect the mounted debugfs directory and write to the files located there
+based on the arguments passed by the user. For example, running
+`inject_faults.sh forget_locks 1` as root will instruct the server to forget
+one lock. Running `inject_faults forget_locks` will instruct the server to
+forgetall locks.

+==========
+NFS Client
+==========
+
+The NFS client
+==============
+
+The NFS version 2 protocol was first documented in RFC1094 (March 1989).
+Since then two more major releases of NFS have been published, with NFSv3
+being documented in RFC1813 (June 1995), and NFSv4 in RFC3530 (April
+2003).
+
+The Linux NFS client currently supports all the above published versions,
+and work is in progress on adding support for minor version 1 of the NFSv4
+protocol.
+
+The purpose of this document is to provide information on some of the
+special features of the NFS client that can be configured by system
+administrators.
+
+
+The nfs4_unique_id parameter
+============================
+
+NFSv4 requires clients to identify themselves to servers with a unique
+string. File open and lock state shared between one client and one server
+is associated with this identity. To support robust NFSv4 state recovery
+and transparent state migration, this identity string must not change
+across client reboots.
+
+Without any other intervention, the Linux client uses a string that contains
+the local system's node name. System administrators, however, often do not
+take care to ensure that node names are fully qualified and do not change
+over the lifetime of a client system. Node names can have other
+administrative requirements that require particular behavior that does not
+work well as part of an nfs_client_id4 string.
+
+The nfs.nfs4_unique_id boot parameter specifies a unique string that can be
+used instead of a system's node name when an NFS client identifies itself to
+a server. Thus, if the system's node name is not unique, or it changes, its
+nfs.nfs4_unique_id stays the same, preventing collision with other clients
+or loss of state during NFS reboot recovery or transparent state migration.
+
+The nfs.nfs4_unique_id string is typically a UUID, though it can contain
+anything that is believed to be unique across all NFS clients. An
+nfs4_unique_id string should be chosen when a client system is installed,
+just as a system's root file system gets a fresh UUID in its label at
+install time.
+
+The string should remain fixed for the lifetime of the client. It can be
+changed safely if care is taken that the client shuts down cleanly and all
+outstanding NFSv4 state has expired, to prevent loss of NFSv4 state.
+
+This string can be stored in an NFS client's grub.conf, or it can be provided
+via a net boot facility such as PXE. It may also be specified as an nfs.ko
+module parameter. Specifying a uniquifier string is not support for NFS
+clients running in containers.
+
+
+The DNS resolver
+================
+
+NFSv4 allows for one server to refer the NFS client to data that has been
+migrated onto another server by means of the special "fs_locations"
+attribute. See `RFC3530 Section 6: Filesystem Migration and Replication`_ and
+`Implementation Guide for Referrals in NFSv4`_.
+
+.. _RFC3530 Section 6\: Filesystem Migration and Replication: http://tools.ietf.org/html/rfc3530#section-6
+.. _Implementation Guide for Referrals in NFSv4: http://tools.ietf.org/html/draft-ietf-nfsv4-referrals-00
+
+The fs_locations information can take the form of either an ip address and
+a path, or a DNS hostname and a path. The latter requires the NFS client to
+do a DNS lookup in order to mount the new volume, and hence the need for an
+upcall to allow userland to provide this service.
+
+Assuming that the user has the 'rpc_pipefs' filesystem mounted in the usual
+/var/lib/nfs/rpc_pipefs, the upcall consists of the following steps:
+
+ (1) The process checks the dns_resolve cache to see if it contains a
+ valid entry. If so, it returns that entry and exits.
+
+ (2) If no valid entry exists, the helper script '/sbin/nfs_cache_getent'
+ (may be changed using the 'nfs.cache_getent' kernel boot parameter)
+ is run, with two arguments:
+ - the cache name, "dns_resolve"
+ - the hostname to resolve
+
+ (3) After looking up the corresponding ip address, the helper script
+ writes the result into the rpc_pipefs pseudo-file
+ '/var/lib/nfs/rpc_pipefs/cache/dns_resolve/channel'
+ in the following (text) format:
+
+ "<ip address> <hostname> <ttl>\n"
+
+ Where <ip address> is in the usual IPv4 (123.456.78.90) or IPv6
+ (ffee:ddcc:bbaa:9988:7766:5544:3322:1100, ffee::1100, ...) format.
+ <hostname> is identical to the second argument of the helper
+ script, and <ttl> is the 'time to live' of this cache entry (in
+ units of seconds).
+
+ .. note::
+ If <ip address> is invalid, say the string "0", then a negative
+ entry is created, which will cause the kernel to treat the hostname
+ as having no valid DNS translation.
+
+
+
+
+A basic sample /sbin/nfs_cache_getent
+=====================================
+.. code-block:: sh
+
+ #!/bin/bash
+ #
+ ttl=600
+ #
+ cut=/usr/bin/cut
+ getent=/usr/bin/getent
+ rpc_pipefs=/var/lib/nfs/rpc_pipefs
+ #
+ die()
+ {
+ echo "Usage: $0 cache_name entry_name"
+ exit 1
+ }
+
+ [ $# -lt 2 ] && die
+ cachename="$1"
+ cache_path=${rpc_pipefs}/cache/${cachename}/channel
+
+ case "${cachename}" in
+ dns_resolve)
+ name="$2"
+ result="$(${getent} hosts ${name} | ${cut} -f1 -d\ )"
+ [ -z "${result}" ] && result="0"
+ ;;
+ *)
+ die
+ ;;
+ esac
+ echo "${result} ${name} ${ttl}" >${cache_path}

+=============
+NFS ID Mapper
+=============
+
+Id mapper is used by NFS to translate user and group ids into names, and to
+translate user and group names into ids. Part of this translation involves
+performing an upcall to userspace to request the information. There are two
+ways NFS could obtain this information: placing a call to /sbin/request-key
+or by placing a call to the rpc.idmap daemon.
+
+NFS will attempt to call /sbin/request-key first. If this succeeds, the
+result will be cached using the generic request-key cache. This call should
+only fail if /etc/request-key.conf is not configured for the id_resolver key
+type, see the "Configuring" section below if you wish to use the request-key
+method.
+
+If the call to /sbin/request-key fails (if /etc/request-key.conf is not
+configured with the id_resolver key type), then the idmapper will ask the
+legacy rpc.idmap daemon for the id mapping. This result will be stored
+in a custom NFS idmap cache.
+
+
+Configuring
+===========
+
+The file /etc/request-key.conf will need to be modified so /sbin/request-key can
+direct the upcall. The following line should be added:
+
+``#OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ...``
+``#====== ======= =============== =============== ===============================``
+``create id_resolver * * /usr/sbin/nfs.idmap %k %d 600``
+
+
+This will direct all id_resolver requests to the program /usr/sbin/nfs.idmap.
+The last parameter, 600, defines how many seconds into the future the key will
+expire. This parameter is optional for /usr/sbin/nfs.idmap. When the timeout
+is not specified, nfs.idmap will default to 600 seconds.
+
+id mapper uses for key descriptions::
+
+ uid: Find the UID for the given user
+ gid: Find the GID for the given group
+ user: Find the user name for the given UID
+ group: Find the group name for the given GID
+
+You can handle any of these individually, rather than using the generic upcall
+program. If you would like to use your own program for a uid lookup then you
+would edit your request-key.conf so it look similar to this:
+
+``#OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ...``
+``#====== ======= =============== =============== ===============================``
+``create id_resolver uid:* * /some/other/program %k %d 600``
+``create id_resolver * * /usr/sbin/nfs.idmap %k %d 600``
+
+
+Notice that the new line was added above the line for the generic program.
+request-key will find the first matching line and corresponding program. In
+this case, /some/other/program will handle all uid lookups and
+/usr/sbin/nfs.idmap will handle gid, user, and group lookups.
+
+See Documentation/security/keys/request-key.rst for more information
+about the request-key function.
+
+
+nfs.idmap
+=========
+
+nfs.idmap is designed to be called by request-key, and should not be run "by
+hand". This program takes two arguments, a serialized key and a key
+description. The serialized key is first converted into a key_serial_t, and
+then passed as an argument to keyctl_instantiate (both are part of keyutils.h).
+
+The actual lookups are performed by functions found in nfsidmap.h. nfs.idmap
+determines the correct function to call by looking at the first part of the
+description string. For example, a uid lookup description will appear as
+"uid:user@domain".
+
+nfs.idmap will return 0 if the key was instantiated, and non-zero otherwise.

+===================
+Setting up NFS/RDMA
+===================
+
+:Author:
+ NetApp and Open Grid Computing (May 29, 2008)
+
+.. warning::
+ This document is probably obsolete.
+
+Overview
+========
+
+This document describes how to install and setup the Linux NFS/RDMA client
+and server software.
+
+The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server
+was first included in the following release, Linux 2.6.25.
+
+In our testing, we have obtained excellent performance results (full 10Gbit
+wire bandwidth at minimal client CPU) under many workloads. The code passes
+the full Connectathon test suite and operates over both Infiniband and iWARP
+RDMA adapters.
+
+Getting Help
+============
+
+If you get stuck, you can ask questions on the
+nfs-rdma-devel@lists.sourceforge.net mailing list.
+
+Installation
+============
+
+These instructions are a step by step guide to building a machine for
+use with NFS/RDMA.
+
+- Install an RDMA device
+
+ Any device supported by the drivers in drivers/infiniband/hw is acceptable.
+
+ Testing has been performed using several Mellanox-based IB cards, the
+ Ammasso AMS1100 iWARP adapter, and the Chelsio cxgb3 iWARP adapter.
+
+- Install a Linux distribution and tools
+
+ The first kernel release to contain both the NFS/RDMA client and server was
+ Linux 2.6.25 Therefore, a distribution compatible with this and subsequent
+ Linux kernel release should be installed.
+
+ The procedures described in this document have been tested with
+ distributions from Red Hat's Fedora Project (http://fedora.redhat.com/).
+
+- Install nfs-utils-1.1.2 or greater on the client
+
+ An NFS/RDMA mount point can be obtained by using the mount.nfs command in
+ nfs-utils-1.1.2 or greater (nfs-utils-1.1.1 was the first nfs-utils
+ version with support for NFS/RDMA mounts, but for various reasons we
+ recommend using nfs-utils-1.1.2 or greater). To see which version of
+ mount.nfs you are using, type:
+
+ .. code-block:: sh
+
+ $ /sbin/mount.nfs -V
+
+ If the version is less than 1.1.2 or the command does not exist,
+ you should install the latest version of nfs-utils.
+
+ Download the latest package from: http://www.kernel.org/pub/linux/utils/nfs
+
+ Uncompress the package and follow the installation instructions.
+
+ If you will not need the idmapper and gssd executables (you do not need
+ these to create an NFS/RDMA enabled mount command), the installation
+ process can be simplified by disabling these features when running
+ configure:
+
+ .. code-block:: sh
+
+ $ ./configure --disable-gss --disable-nfsv4
+
+ To build nfs-utils you will need the tcp_wrappers package installed. For
+ more information on this see the package's README and INSTALL files.
+
+ After building the nfs-utils package, there will be a mount.nfs binary in
+ the utils/mount directory. This binary can be used to initiate NFS v2, v3,
+ or v4 mounts. To initiate a v4 mount, the binary must be called
+ mount.nfs4. The standard technique is to create a symlink called
+ mount.nfs4 to mount.nfs.
+
+ This mount.nfs binary should be installed at /sbin/mount.nfs as follows:
+
+ .. code-block:: sh
+
+ $ sudo cp utils/mount/mount.nfs /sbin/mount.nfs
+
+ In this location, mount.nfs will be invoked automatically for NFS mounts
+ by the system mount command.
+
+ .. note::
+ mount.nfs and therefore nfs-utils-1.1.2 or greater is only needed
+ on the NFS client machine. You do not need this specific version of
+ nfs-utils on the server. Furthermore, only the mount.nfs command from
+ nfs-utils-1.1.2 is needed on the client.
+
+- Install a Linux kernel with NFS/RDMA
+
+ The NFS/RDMA client and server are both included in the mainline Linux
+ kernel version 2.6.25 and later. This and other versions of the Linux
+ kernel can be found at: https://www.kernel.org/pub/linux/kernel/
+
+ Download the sources and place them in an appropriate location.
+
+- Configure the RDMA stack
+
+ Make sure your kernel configuration has RDMA support enabled. Under
+ Device Drivers -> InfiniBand support, update the kernel configuration
+ to enable InfiniBand support [NOTE: the option name is misleading. Enabling
+ InfiniBand support is required for all RDMA devices (IB, iWARP, etc.)].
+
+ Enable the appropriate IB HCA support (mlx4, mthca, ehca, ipath, etc.) or
+ iWARP adapter support (amso, cxgb3, etc.).
+
+ If you are using InfiniBand, be sure to enable IP-over-InfiniBand support.
+
+- Configure the NFS client and server
+
+ Your kernel configuration must also have NFS file system support and/or
+ NFS server support enabled. These and other NFS related configuration
+ options can be found under File Systems -> Network File Systems.
+
+- Build, install, reboot
+
+ The NFS/RDMA code will be enabled automatically if NFS and RDMA
+ are turned on. The NFS/RDMA client and server are configured via the hidden
+ SUNRPC_XPRT_RDMA config option that depends on SUNRPC and INFINIBAND. The
+ value of SUNRPC_XPRT_RDMA will be:
+
+ #. N if either SUNRPC or INFINIBAND are N, in this case the NFS/RDMA client
+ and server will not be built
+
+ #. M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M,
+ in this case the NFS/RDMA client and server will be built as modules
+
+ #. Y if both SUNRPC and INFINIBAND are Y, in this case the NFS/RDMA client
+ and server will be built into the kernel
+
+ Therefore, if you have followed the steps above and turned no NFS and RDMA,
+ the NFS/RDMA client and server will be built.
+
+ Build a new kernel, install it, boot it.
+
+Check RDMA and NFS Setup
+========================
+
+Before configuring the NFS/RDMA software, it is a good idea to test
+your new kernel to ensure that the kernel is working correctly.
+In particular, it is a good idea to verify that the RDMA stack
+is functioning as expected and standard NFS over TCP/IP and/or UDP/IP
+is working properly.
+
+- Check RDMA Setup
+
+ If you built the RDMA components as modules, load them at
+ this time. For example, if you are using a Mellanox Tavor/Sinai/Arbel
+ card:
+
+ .. code-block:: sh
+
+ $ modprobe ib_mthca
+ $ modprobe ib_ipoib
+
+ If you are using InfiniBand, make sure there is a Subnet Manager (SM)
+ running on the network. If your IB switch has an embedded SM, you can
+ use it. Otherwise, you will need to run an SM, such as OpenSM, on one
+ of your end nodes.
+
+ If an SM is running on your network, you should see the following:
+
+ .. code-block:: sh
+
+ $ cat /sys/class/infiniband/driverX/ports/1/state
+ 4: ACTIVE
+
+ where driverX is mthca0, ipath5, ehca3, etc.
+
+ To further test the InfiniBand software stack, use IPoIB (this
+ assumes you have two IB hosts named host1 and host2):
+
+ .. code-block:: sh
+
+ host1$ ip link set dev ib0 up
+ host1$ ip address add dev ib0 a.b.c.x
+ host2$ ip link set dev ib0 up
+ host2$ ip address add dev ib0 a.b.c.y
+ host1$ ping a.b.c.y
+ host2$ ping a.b.c.x
+
+ For other device types, follow the appropriate procedures.
+
+- Check NFS Setup
+
+ For the NFS components enabled above (client and/or server),
+ test their functionality over standard Ethernet using TCP/IP or UDP/IP.
+
+NFS/RDMA Setup
+==============
+
+We recommend that you use two machines, one to act as the client and
+one to act as the server.
+
+One time configuration:
+-----------------------
+
+- On the server system, configure the /etc/exports file and start the NFS/RDMA server.
+
+ Exports entries with the following formats have been tested::
+
+ /vol0 192.168.0.47(fsid=0,rw,async,insecure,no_root_squash)
+ /vol0 192.168.0.0/255.255.255.0(fsid=0,rw,async,insecure,no_root_squash)
+
+ The IP address(es) is(are) the client's IPoIB address for an InfiniBand
+ HCA or the client's iWARP address(es) for an RNIC.
+
+ .. note::
+ The "insecure" option must be used because the NFS/RDMA client does
+ not use a reserved port.
+
+Each time a machine boots:
+--------------------------
+
+- Load and configure the RDMA drivers
+
+ For InfiniBand using a Mellanox adapter:
+
+ .. code-block:: sh
+
+ $ modprobe ib_mthca
+ $ modprobe ib_ipoib
+ $ ip li set dev ib0 up
+ $ ip addr add dev ib0 a.b.c.d
+
+ .. note::
+ Please use unique addresses for the client and server!
+
+- Start the NFS server
+
+ If the NFS/RDMA server was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
+ kernel config), load the RDMA transport module:
+
+ .. code-block:: sh
+
+ $ modprobe svcrdma
+
+ Regardless of how the server was built (module or built-in), start the
+ server:
+
+ .. code-block:: sh
+
+ $ /etc/init.d/nfs start
+
+ or
+
+ .. code-block:: sh
+
+ $ service nfs start
+
+ Instruct the server to listen on the RDMA transport:
+
+ .. code-block:: sh
+
+ $ echo rdma 20049 > /proc/fs/nfsd/portlist
+
+- On the client system
+
+ If the NFS/RDMA client was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
+ kernel config), load the RDMA client module:
+
+ .. code-block:: sh
+
+ $ modprobe xprtrdma.ko
+
+ Regardless of how the client was built (module or built-in), use this
+ command to mount the NFS/RDMA server:
+
+ .. code-block:: sh
+
+ $ mount -o rdma,port=20049 <IPoIB-server-name-or-address>:/<export> /mnt
+
+ To verify that the mount is using RDMA, run "cat /proc/mounts" and check
+ the "proto" field for the given mount.
+
+ Congratulations! You're using NFS/RDMA!

+==================================
+Administrative interfaces for nfsd
+==================================
+
+Note that normally these interfaces are used only by the utilities in
+nfs-utils.
+
+nfsd is controlled mainly by pseudofiles under the "nfsd" filesystem,
+which is normally mounted at /proc/fs/nfsd/.
+
+The server is always started by the first write of a nonzero value to
+nfsd/threads.
+
+Before doing that, NFSD can be told which sockets to listen on by
+writing to nfsd/portlist; that write may be:
+
+ - an ascii-encoded file descriptor, which should refer to a
+ bound (and listening, for tcp) socket, or
+ - "transportname port", where transportname is currently either
+ "udp", "tcp", or "rdma".
+
+If nfsd is started without doing any of these, then it will create one
+udp and one tcp listener at port 2049 (see nfsd_init_socks).
+
+On startup, nfsd and lockd grace periods start. nfsd is shut down by a write of
+0 to nfsd/threads. All locks and state are thrown away at that point.
+
+Between startup and shutdown, the number of threads may be adjusted up
+or down by additional writes to nfsd/threads or by writes to
+nfsd/pool_threads.
+
+For more detail about files under nfsd/ and what they control, see
+fs/nfsd/nfsctl.c; most of them have detailed comments.
+
+Implementation notes
+====================
+
+Note that the rpc server requires the caller to serialize addition and
+removal of listening sockets, and startup and shutdown of the server.
+For nfsd this is done using nfsd_mutex.

+===============================================
+Mounting the root filesystem via NFS (nfsroot)
+===============================================
+

+

+
+
+
+In order to use a diskless system, such as an X-terminal or printer server for
+example, it is necessary for the root filesystem to be present on a non-disk
+device. This may be an initramfs (see
+Documentation/filesystems/ramfs-rootfs-initramfs.txt), a ramdisk (see
+Documentation/admin-guide/initrd.rst) or a filesystem mounted via NFS. The
+following text describes on how to use NFS for the root filesystem. For the rest
+of this text 'client' means the diskless system, and 'server' means the NFS
+server.
+
+
+
+
+Enabling nfsroot capabilities
+=============================
+
+In order to use nfsroot, NFS client support needs to be selected as
+built-in during configuration. Once this has been selected, the nfsroot
+option will become available, which should also be selected.
+
+In the networking options, kernel level autoconfiguration can be selected,
+along with the types of autoconfiguration to support. Selecting all of
+DHCP, BOOTP and RARP is safe.
+
+
+
+
+Kernel command line
+===================
+
+When the kernel has been loaded by a boot loader (see below) it needs to be
+told what root fs device to use. And in the case of nfsroot, where to find
+both the server and the name of the directory on the server to mount as root.
+This can be established using the following kernel command line parameters:
+
+
+root=/dev/nfs
+ This is necessary to enable the pseudo-NFS-device. Note that it's not a
+ real device but just a synonym to tell the kernel to use NFS instead of
+ a real device.
+
+
+nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
+ If the `nfsroot' parameter is NOT given on the command line,
+ the default ``"/tftpboot/%s"`` will be used.
+
+ <server-ip> Specifies the IP address of the NFS server.
+ The default address is determined by the ip parameter
+ (see below). This parameter allows the use of different
+ servers for IP autoconfiguration and NFS.
+
+ <root-dir> Name of the directory on the server to mount as root.
+ If there is a "%s" token in the string, it will be
+ replaced by the ASCII-representation of the client's
+ IP address.
+
+ <nfs-options> Standard NFS options. All options are separated by commas.
+ The following defaults are used::
+
+ port = as given by server portmap daemon
+ rsize = 4096
+ wsize = 4096
+ timeo = 7
+ retrans = 3
+ acregmin = 3
+ acregmax = 60
+ acdirmin = 30
+ acdirmax = 60
+ flags = hard, nointr, noposix, cto, ac
+
+
+ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>:<dns0-ip>:<dns1-ip>:<ntp0-ip>
+ This parameter tells the kernel how to configure IP addresses of devices
+ and also how to set up the IP routing table. It was originally called
+ nfsaddrs, but now the boot-time IP configuration works independently of
+ NFS, so it was renamed to ip and the old name remained as an alias for
+ compatibility reasons.
+
+ If this parameter is missing from the kernel command line, all fields are
+ assumed to be empty, and the defaults mentioned below apply. In general
+ this means that the kernel tries to configure everything using
+ autoconfiguration.
+
+ The <autoconf> parameter can appear alone as the value to the ip
+ parameter (without all the ':' characters before). If the value is
+ "ip=off" or "ip=none", no autoconfiguration will take place, otherwise
+ autoconfiguration will take place. The most common way to use this
+ is "ip=dhcp".
+
+ <client-ip> IP address of the client.
+ Default: Determined using autoconfiguration.

+ (old option kept for backwards compatibility)
+
+ if dhcp is used, the client identifier can be used by following

+ Value is exported to /proc/net/ipconfig/ntp_servers, but is
+ otherwise unused (see below).
+
+ Default: None if not using autoconfiguration; determined
+ automatically if using autoconfiguration.
+
+ After configuration (whether manual or automatic) is complete, two files
+ are created in the following format; lines are omitted if their respective

+
+ - /proc/net/pnp:
+

+ (in /proc/net/ipconfig/ntp_servers) are requested during autoconfiguration;
+ they cannot be specified as part of the "ip=" kernel command line parameter.
+
+ Because the "domain" and "nameserver" options are recognised by DNS
+ resolvers, /etc/resolv.conf is often linked to /proc/net/pnp on systems
+ that use an NFS root filesystem.
+
+ Note that the kernel will not synchronise the system time with any NTP
+ servers it discovers; this is the responsibility of a user space process
+ (e.g. an initrd/initramfs script that passes the IP addresses listed in
+ /proc/net/ipconfig/ntp_servers to an NTP client before mounting the real
+ root filesystem if it is on NFS).
+
+
+nfsrootdebug
+ This parameter enables debugging messages to appear in the kernel
+ log at boot time so that administrators can verify that the correct
+ NFS mount options, server address, and root path are passed to the
+ NFS client.
+
+
+rdinit=<executable file>
+ To specify which file contains the program that starts system
+ initialization, administrators can use this command line parameter.
+ The default value of this parameter is "/init". If the specified
+ file exists and the kernel can execute it, root filesystem related
+ kernel command line parameters, including 'nfsroot=', are ignored.
+
+ A description of the process of mounting the root file system can be

+
+
+Boot Loader
+===========
+
+To get the kernel into memory different approaches can be used.
+They depend on various facilities being available:
+
+
+- Booting from a floppy using syslinux
+
+ When building kernels, an easy way to create a boot floppy that uses
+ syslinux is to use the zdisk or bzdisk make targets which use zimage
+ and bzimage images respectively. Both targets accept the
+ FDARGS parameter which can be used to set the kernel command line.
+
+ e.g::
+
+ make bzdisk FDARGS="root=/dev/nfs"
+
+ Note that the user running this command will need to have
+ access to the floppy drive device, /dev/fd0
+
+ For more information on syslinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
+
+ .. note::
+ Previously it was possible to write a kernel directly to
+ a floppy using dd, configure the boot device using rdev, and
+ boot using the resulting floppy. Linux no longer supports this
+ method of booting.
+
+- Booting from a cdrom using isolinux
+
+ When building kernels, an easy way to create a bootable cdrom that
+ uses isolinux is to use the isoimage target which uses a bzimage
+ image. Like zdisk and bzdisk, this target accepts the FDARGS
+ parameter which can be used to set the kernel command line.
+
+ e.g::
+
+ make isoimage FDARGS="root=/dev/nfs"
+
+ The resulting iso image will be arch/<ARCH>/boot/image.iso
+ This can be written to a cdrom using a variety of tools including
+ cdrecord.
+
+ e.g::
+
+ cdrecord dev=ATAPI:1,0,0 arch/x86/boot/image.iso
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
+
+- Using LILO
+
+ When using LILO all the necessary command line parameters may be
+ specified using the 'append=' directive in the LILO configuration
+ file.
+
+ However, to use the 'root=' directive you also need to create
+ a dummy root device, which may be removed after LILO is run.
+
+ e.g::
+
+ mknod /dev/boot255 c 0 255
+
+ For information on configuring LILO, please refer to its documentation.
+
+- Using GRUB
+
+ When using GRUB, kernel parameter are simply appended after the kernel
+ specification: kernel <kernel> <parameters>
+
+- Using loadlin
+
+ loadlin may be used to boot Linux from a DOS command prompt without
+ requiring a local hard disk to mount as root. This has not been
+ thoroughly tested by the authors of this document, but in general
+ it should be possible configure the kernel command line similarly
+ to the configuration of LILO.
+
+ Please refer to the loadlin documentation for further information.
+
+- Using a boot ROM
+
+ This is probably the most elegant way of booting a diskless client.
+ With a boot ROM the kernel is loaded using the TFTP protocol. The
+ authors of this document are not aware of any no commercial boot
+ ROMs that support booting Linux over the network. However, there
+ are two free implementations of a boot ROM, netboot-nfs and
+ etherboot, both of which are available on sunsite.unc.edu, and both
+ of which contain everything you need to boot a diskless Linux client.
+
+- Using pxelinux
+
+ Pxelinux may be used to boot linux using the PXE boot loader
+ which is present on many modern network cards.
+
+ When using pxelinux, the kernel image is specified using
+ "kernel <relative-path-below /tftpboot>". The nfsroot parameters
+ are passed to the kernel by adding them to the "append" line.
+ It is common to use serial console in conjunction with pxeliunx,
+ see Documentation/admin-guide/serial-console.rst for more information.
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/

+======================
+ioctl based interfaces
+======================
+
+ioctl() is the most common way for applications to interface
+with device drivers. It is flexible and easily extended by adding new
+commands and can be passed through character devices, block devices as
+well as sockets and other special file descriptors.
+
+However, it is also very easy to get ioctl command definitions wrong,
+and hard to fix them later without breaking existing applications,
+so this documentation tries to help developers get it right.
+
+Command number definitions
+==========================
+
+The command number, or request number, is the second argument passed to
+the ioctl system call. While this can be any 32-bit number that uniquely
+identifies an action for a particular driver, there are a number of
+conventions around defining them.
+
+``include/uapi/asm-generic/ioctl.h`` provides four macros for defining
+ioctl commands that follow modern conventions: ``_IO``, ``_IOR``,
+``_IOW``, and ``_IOWR``. These should be used for all new commands,
+with the correct parameters:
+
+_IO/_IOR/_IOW/_IOWR
+ The macro name specifies how the argument will be used. It may be a
+ pointer to data to be passed into the kernel (_IOW), out of the kernel
+ (_IOR), or both (_IOWR). _IO can indicate either commands with no
+ argument or those passing an integer value instead of a pointer.
+ It is recommended to only use _IO for commands without arguments,
+ and use pointers for passing data.
+
+type
+ An 8-bit number, often a character literal, specific to a subsystem
+ or driver, and listed in :doc:`../userspace-api/ioctl/ioctl-number`
+
+nr
+ An 8-bit number identifying the specific command, unique for a give
+ value of 'type'
+
+data_type
+ The name of the data type pointed to by the argument, the command number
+ encodes the ``sizeof(data_type)`` value in a 13-bit or 14-bit integer,
+ leading to a limit of 8191 bytes for the maximum size of the argument.
+ Note: do not pass sizeof(data_type) type into _IOR/_IOW/IOWR, as that
+ will lead to encoding sizeof(sizeof(data_type)), i.e. sizeof(size_t).
+ _IO does not have a data_type parameter.
+
+
+Interface versions
+==================
+
+Some subsystems use version numbers in data structures to overload
+commands with different interpretations of the argument.
+
+This is generally a bad idea, since changes to existing commands tend
+to break existing applications.
+
+A better approach is to add a new ioctl command with a new number. The
+old command still needs to be implemented in the kernel for compatibility,
+but this can be a wrapper around the new implementation.
+
+Return code
+===========
+
+ioctl commands can return negative error codes as documented in errno(3);
+these get turned into errno values in user space. On success, the return
+code should be zero. It is also possible but not recommended to return
+a positive 'long' value.
+
+When the ioctl callback is called with an unknown command number, the
+handler returns either -ENOTTY or -ENOIOCTLCMD, which also results in
+-ENOTTY being returned from the system call. Some subsystems return
+-ENOSYS or -EINVAL here for historic reasons, but this is wrong.
+
+Prior to Linux 5.5, compat_ioctl handlers were required to return
+-ENOIOCTLCMD in order to use the fallback conversion into native
+commands. As all subsystems are now responsible for handling compat
+mode themselves, this is no longer needed, but it may be important to
+consider when backporting bug fixes to older kernels.
+
+Timestamps
+==========
+
+Traditionally, timestamps and timeout values are passed as ``struct
+timespec`` or ``struct timeval``, but these are problematic because of
+incompatible definitions of these structures in user space after the
+move to 64-bit time_t.
+
+The ``struct __kernel_timespec`` type can be used instead to be embedded
+in other data structures when separate second/nanosecond values are
+desired, or passed to user space directly. This is still not ideal though,
+as the structure matches neither the kernel's timespec64 nor the user
+space timespec exactly. The get_timespec64() and put_timespec64() helper
+functions can be used to ensure that the layout remains compatible with
+user space and the padding is treated correctly.
+
+As it is cheap to convert seconds to nanoseconds, but the opposite
+requires an expensive 64-bit division, a simple __u64 nanosecond value
+can be simpler and more efficient.
+
+Timeout values and timestamps should ideally use CLOCK_MONOTONIC time,
+as returned by ktime_get_ns() or ktime_get_ts64(). Unlike
+CLOCK_REALTIME, this makes the timestamps immune from jumping backwards
+or forwards due to leap second adjustments and clock_settime() calls.
+
+ktime_get_real_ns() can be used for CLOCK_REALTIME timestamps that
+need to be persistent across a reboot or between multiple machines.
+
+32-bit compat mode
+==================
+
+In order to support 32-bit user space running on a 64-bit machine, each
+subsystem or driver that implements an ioctl callback handler must also
+implement the corresponding compat_ioctl handler.
+
+As long as all the rules for data structures are followed, this is as
+easy as setting the .compat_ioctl pointer to a helper function such as
+compat_ptr_ioctl() or blkdev_compat_ptr_ioctl().
+
+compat_ptr()
+------------
+
+On the s390 architecture, 31-bit user space has ambiguous representations
+for data pointers, with the upper bit being ignored. When running such
+a process in compat mode, the compat_ptr() helper must be used to
+clear the upper bit of a compat_uptr_t and turn it into a valid 64-bit
+pointer. On other architectures, this macro only performs a cast to a
+``void __user *`` pointer.
+
+In an compat_ioctl() callback, the last argument is an unsigned long,
+which can be interpreted as either a pointer or a scalar depending on
+the command. If it is a scalar, then compat_ptr() must not be used, to
+ensure that the 64-bit kernel behaves the same way as a 32-bit kernel
+for arguments with the upper bit set.
+
+The compat_ptr_ioctl() helper can be used in place of a custom
+compat_ioctl file operation for drivers that only take arguments that
+are pointers to compatible data structures.
+
+Structure layout
+----------------
+
+Compatible data structures have the same layout on all architectures,
+avoiding all problematic members:
+
+* ``long`` and ``unsigned long`` are the size of a register, so
+ they can be either 32-bit or 64-bit wide and cannot be used in portable
+ data structures. Fixed-length replacements are ``__s32``, ``__u32``,
+ ``__s64`` and ``__u64``.
+
+* Pointers have the same problem, in addition to requiring the
+ use of compat_ptr(). The best workaround is to use ``__u64``
+ in place of pointers, which requires a cast to ``uintptr_t`` in user
+ space, and the use of u64_to_user_ptr() in the kernel to convert
+ it back into a user pointer.
+
+* On the x86-32 (i386) architecture, the alignment of 64-bit variables
+ is only 32-bit, but they are naturally aligned on most other
+ architectures including x86-64. This means a structure like::
+
+ struct foo {
+ __u32 a;
+ __u64 b;
+ __u32 c;
+ };
+
+ has four bytes of padding between a and b on x86-64, plus another four
+ bytes of padding at the end, but no padding on i386, and it needs a
+ compat_ioctl conversion handler to translate between the two formats.
+
+ To avoid this problem, all structures should have their members
+ naturally aligned, or explicit reserved fields added in place of the
+ implicit padding. The ``pahole`` tool can be used for checking the
+ alignment.
+
+* On ARM OABI user space, structures are padded to multiples of 32-bit,
+ making some structs incompatible with modern EABI kernels if they
+ do not end on a 32-bit boundary.
+
+* On the m68k architecture, struct members are not guaranteed to have an
+ alignment greater than 16-bit, which is a problem when relying on
+ implicit padding.
+
+* Bitfields and enums generally work as one would expect them to,
+ but some properties of them are implementation-defined, so it is better
+ to avoid them completely in ioctl interfaces.
+
+* ``char`` members can be either signed or unsigned, depending on
+ the architecture, so the __u8 and __s8 types should be used for 8-bit
+ integer values, though char arrays are clearer for fixed-length strings.
+
+Information leaks
+=================
+
+Uninitialized data must not be copied back to user space, as this can
+cause an information leak, which can be used to defeat kernel address
+space layout randomization (KASLR), helping in an attack.
+
+For this reason (and for compat support) it is best to avoid any
+implicit padding in data structures. Where there is implicit padding
+in an existing structure, kernel drivers must be careful to fully
+initialize an instance of the structure before copying it to user
+space. This is usually done by calling memset() before assigning to
+individual members.
+
+Subsystem abstractions
+======================
+
+While some device drivers implement their own ioctl function, most
+subsystems implement the same command for multiple drivers. Ideally the
+subsystem has an .ioctl() handler that copies the arguments from and
+to user space, passing them into subsystem specific callback functions
+through normal kernel pointers.
+
+This helps in various ways:
+
+* Applications written for one driver are more likely to work for
+ another one in the same subsystem if there are no subtle differences
+ in the user space ABI.
+
+* The complexity of user space access and data structure layout is done
+ in one place, reducing the potential for implementation bugs.
+
+* It is more likely to be reviewed by experienced developers
+ that can spot problems in the interface when the ioctl is shared
+ between multiple drivers than when it is only used in a single driver.
+
+Alternatives to ioctl
+=====================
+
+There are many cases in which ioctl is not the best solution for a
+problem. Alternatives include:
+
+* System calls are a better choice for a system-wide feature that
+ is not tied to a physical device or constrained by the file system
+ permissions of a character device node
+
+* netlink is the preferred way of configuring any network related
+ objects through sockets.
+
+* debugfs is used for ad-hoc interfaces for debugging functionality
+ that does not need to be exposed as a stable interface to applications.
+
+* sysfs is a good way to expose the state of an in-kernel object
+ that is not tied to a file descriptor.
+
+* configfs can be used for more complex configuration than sysfs
+
+* A custom file system can provide extra flexibility with a simple
+ user interface but adds a lot of complexity to the implementation.

+pin_user_pages() and related calls
+====================================================
+
+.. contents:: :local:
+
+Overview
+========
+
+This document describes the following functions::
+
+ pin_user_pages()
+ pin_user_pages_fast()
+ pin_user_pages_remote()
+
+Basic description of FOLL_PIN
+=============================
+
+FOLL_PIN and FOLL_LONGTERM are flags that can be passed to the get_user_pages*()
+("gup") family of functions. FOLL_PIN has significant interactions and
+interdependencies with FOLL_LONGTERM, so both are covered here.
+
+FOLL_PIN is internal to gup, meaning that it should not appear at the gup call
+sites. This allows the associated wrapper functions (pin_user_pages*() and
+others) to set the correct combination of these flags, and to check for problems
+as well.
+
+FOLL_LONGTERM, on the other hand, *is* allowed to be set at the gup call sites.
+This is in order to avoid creating a large number of wrapper functions to cover
+all combinations of get*(), pin*(), FOLL_LONGTERM, and more. Also, the
+pin_user_pages*() APIs are clearly distinct from the get_user_pages*() APIs, so
+that's a natural dividing line, and a good point to make separate wrapper calls.
+In other words, use pin_user_pages*() for DMA-pinned pages, and
+get_user_pages*() for other cases. There are four cases described later on in
+this document, to further clarify that concept.
+
+FOLL_PIN and FOLL_GET are mutually exclusive for a given gup call. However,
+multiple threads and call sites are free to pin the same struct pages, via both
+FOLL_PIN and FOLL_GET. It's just the call site that needs to choose one or the
+other, not the struct page(s).
+
+The FOLL_PIN implementation is nearly the same as FOLL_GET, except that FOLL_PIN
+uses a different reference counting technique.
+
+FOLL_PIN is a prerequisite to FOLL_LONGTERM. Another way of saying that is,
+FOLL_LONGTERM is a specific case, more restrictive case of FOLL_PIN.
+
+Which flags are set by each wrapper
+===================================
+
+For these pin_user_pages*() functions, FOLL_PIN is OR'd in with whatever gup
+flags the caller provides. The caller is required to pass in a non-null struct
+pages* array, and the function then pin pages by incrementing each by a special
+value. For now, that value is +1, just like get_user_pages*().::
+
+ Function
+ --------
+ pin_user_pages FOLL_PIN is always set internally by this function.
+ pin_user_pages_fast FOLL_PIN is always set internally by this function.
+ pin_user_pages_remote FOLL_PIN is always set internally by this function.
+
+For these get_user_pages*() functions, FOLL_GET might not even be specified.
+Behavior is a little more complex than above. If FOLL_GET was *not* specified,
+but the caller passed in a non-null struct pages* array, then the function
+sets FOLL_GET for you, and proceeds to pin pages by incrementing the refcount
+of each page by +1.::
+
+ Function
+ --------
+ get_user_pages FOLL_GET is sometimes set internally by this function.
+ get_user_pages_fast FOLL_GET is sometimes set internally by this function.
+ get_user_pages_remote FOLL_GET is sometimes set internally by this function.
+
+Tracking dma-pinned pages
+=========================
+
+Some of the key design constraints, and solutions, for tracking dma-pinned
+pages:
+
+* An actual reference count, per struct page, is required. This is because
+ multiple processes may pin and unpin a page.
+
+* False positives (reporting that a page is dma-pinned, when in fact it is not)
+ are acceptable, but false negatives are not.
+
+* struct page may not be increased in size for this, and all fields are already
+ used.
+
+* Given the above, we can overload the page->_refcount field by using, sort of,
+ the upper bits in that field for a dma-pinned count. "Sort of", means that,
+ rather than dividing page->_refcount into bit fields, we simple add a medium-
+ large value (GUP_PIN_COUNTING_BIAS, initially chosen to be 1024: 10 bits) to
+ page->_refcount. This provides fuzzy behavior: if a page has get_page() called
+ on it 1024 times, then it will appear to have a single dma-pinned count.
+ And again, that's acceptable.
+
+This also leads to limitations: there are only 31-10==21 bits available for a
+counter that increments 10 bits at a time.
+
+TODO: for 1GB and larger huge pages, this is cutting it close. That's because
+when pin_user_pages() follows such pages, it increments the head page by "1"
+(where "1" used to mean "+1" for get_user_pages(), but now means "+1024" for
+pin_user_pages()) for each tail page. So if you have a 1GB huge page:
+
+* There are 256K (18 bits) worth of 4 KB tail pages.
+* There are 21 bits available to count up via GUP_PIN_COUNTING_BIAS (that is,
+ 10 bits at a time)
+* There are 21 - 18 == 3 bits available to count. Except that there aren't,
+ because you need to allow for a few normal get_page() calls on the head page,
+ as well. Fortunately, the approach of using addition, rather than "hard"
+ bitfields, within page->_refcount, allows for sharing these bits gracefully.
+ But we're still looking at about 8 references.
+
+This, however, is a missing feature more than anything else, because it's easily
+solved by addressing an obvious inefficiency in the original get_user_pages()
+approach of retrieving pages: stop treating all the pages as if they were
+PAGE_SIZE. Retrieve huge pages as huge pages. The callers need to be aware of
+this, so some work is required. Once that's in place, this limitation mostly
+disappears from view, because there will be ample refcounting range available.
+
+* Callers must specifically request "dma-pinned tracking of pages". In other
+ words, just calling get_user_pages() will not suffice; a new set of functions,
+ pin_user_page() and related, must be used.
+
+FOLL_PIN, FOLL_GET, FOLL_LONGTERM: when to use which flags
+==========================================================
+
+Thanks to Jan Kara, Vlastimil Babka and several other -mm people, for describing
+these categories:
+
+CASE 1: Direct IO (DIO)
+-----------------------
+There are GUP references to pages that are serving
+as DIO buffers. These buffers are needed for a relatively short time (so they
+are not "long term"). No special synchronization with page_mkclean() or
+munmap() is provided. Therefore, flags to set at the call site are: ::
+
+ FOLL_PIN
+
+...but rather than setting FOLL_PIN directly, call sites should use one of
+the pin_user_pages*() routines that set FOLL_PIN.
+
+CASE 2: RDMA
+------------
+There are GUP references to pages that are serving as DMA
+buffers. These buffers are needed for a long time ("long term"). No special
+synchronization with page_mkclean() or munmap() is provided. Therefore, flags
+to set at the call site are: ::
+
+ FOLL_PIN | FOLL_LONGTERM
+
+NOTE: Some pages, such as DAX pages, cannot be pinned with longterm pins. That's
+because DAX pages do not have a separate page cache, and so "pinning" implies
+locking down file system blocks, which is not (yet) supported in that way.
+
+CASE 3: Hardware with page faulting support
+-------------------------------------------
+Here, a well-written driver doesn't normally need to pin pages at all. However,
+if the driver does choose to do so, it can register MMU notifiers for the range,
+and will be called back upon invalidation. Either way (avoiding page pinning, or
+using MMU notifiers to unpin upon request), there is proper synchronization with
+both filesystem and mm (page_mkclean(), munmap(), etc).
+
+Therefore, neither flag needs to be set.
+
+In this case, ideally, neither get_user_pages() nor pin_user_pages() should be
+called. Instead, the software should be written so that it does not pin pages.
+This allows mm and filesystems to operate more efficiently and reliably.
+
+CASE 4: Pinning for struct page manipulation only
+-------------------------------------------------
+Here, normal GUP calls are sufficient, so neither flag needs to be set.
+
+page_dma_pinned(): the whole point of pinning
+=============================================
+
+The whole point of marking pages as "DMA-pinned" or "gup-pinned" is to be able
+to query, "is this page DMA-pinned?" That allows code such as page_mkclean()
+(and file system writeback code in general) to make informed decisions about
+what to do when a page cannot be unmapped due to such pins.
+
+What to do in those cases is the subject of a years-long series of discussions
+and debates (see the References at the end of this document). It's a TODO item
+here: fill in the details once that's worked out. Meanwhile, it's safe to say
+that having this available: ::
+
+ static inline bool page_dma_pinned(struct page *page)
+
+...is a prerequisite to solving the long-running gup+DMA problem.
+
+Another way of thinking about FOLL_GET, FOLL_PIN, and FOLL_LONGTERM
+===================================================================
+
+Another way of thinking about these flags is as a progression of restrictions:
+FOLL_GET is for struct page manipulation, without affecting the data that the
+struct page refers to. FOLL_PIN is a *replacement* for FOLL_GET, and is for
+short term pins on pages whose data *will* get accessed. As such, FOLL_PIN is
+a "more severe" form of pinning. And finally, FOLL_LONGTERM is an even more
+restrictive case that has FOLL_PIN as a prerequisite: this is for pages that
+will be pinned longterm, and whose data will be accessed.
+
+Unit testing
+============
+This file::
+
+ tools/testing/selftests/vm/gup_benchmark.c
+
+has the following new calls to exercise the new pin*() wrapper functions:
+
+* PIN_FAST_BENCHMARK (./gup_benchmark -a)
+* PIN_BENCHMARK (./gup_benchmark -b)
+
+You can monitor how many total dma-pinned pages have been acquired and released
+since the system was booted, via two new /proc/vmstat entries: ::
+
+ /proc/vmstat/nr_foll_pin_requested
+ /proc/vmstat/nr_foll_pin_requested
+
+Those are both going to show zero, unless CONFIG_DEBUG_VM is set. This is
+because there is a noticeable performance drop in unpin_user_page(), when they
+are activated.

-ARM idle states binding description
-==========================================
-
-==========================================
-1 - Introduction
-==========================================
-
-ARM systems contain HW capable of managing power consumption dynamically,
-where cores can be put in different low-power states (ranging from simple
-wfi to power gating) according to OS PM policies. The CPU states representing
-the range of dynamic idle states that a processor can enter at run-time, can be
-specified through device tree bindings representing the parameters required
-to enter/exit specific idle states on a given processor.
-
-According to the Server Base System Architecture document (SBSA, [3]), the
-power states an ARM CPU can be put into are identified by the following list:
-
-- Running
-- Idle_standby
-- Idle_retention
-- Sleep
-- Off
-
-The power states described in the SBSA document define the basic CPU states on
-top of which ARM platforms implement power management schemes that allow an OS
-PM implementation to put the processor in different idle states (which include
-states listed above; "off" state is not an idle state since it does not have
-wake-up capabilities, hence it is not considered in this document).
-
-Idle state parameters (e.g. entry latency) are platform specific and need to be
-characterized with bindings that provide the required information to OS PM
-code so that it can build the required tables and use them at runtime.
-
-The device tree binding definition for ARM idle states is the subject of this
-document.
-
-===========================================
-2 - idle-states definitions
-===========================================
-
-Idle states are characterized for a specific system through a set of
-timing and energy related properties, that underline the HW behaviour
-triggered upon idle states entry and exit.
-
-The following diagram depicts the CPU execution phases and related timing
-properties required to enter and exit an idle state:
-
-..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
- | | | | |
-
- |<------ entry ------->|
- | latency |
- |<- exit ->|
- | latency |
- |<-------- min-residency -------->|
- |<------- wakeup-latency ------->|
-
- Diagram 1: CPU idle state execution phases
-
-EXEC: Normal CPU execution.
-
-PREP: Preparation phase before committing the hardware to idle mode
- like cache flushing. This is abortable on pending wake-up
- event conditions. The abort latency is assumed to be negligible
- (i.e. less than the ENTRY + EXIT duration). If aborted, CPU
- goes back to EXEC. This phase is optional. If not abortable,
- this should be included in the ENTRY phase instead.
-
-ENTRY: The hardware is committed to idle mode. This period must run
- to completion up to IDLE before anything else can happen.
-
-IDLE: This is the actual energy-saving idle period. This may last
- between 0 and infinite time, until a wake-up event occurs.
-
-EXIT: Period during which the CPU is brought back to operational
- mode (EXEC).
-
-entry-latency: Worst case latency required to enter the idle state. The
-exit-latency may be guaranteed only after entry-latency has passed.
-
-min-residency: Minimum period, including preparation and entry, for a given
-idle state to be worthwhile energywise.
-
-wakeup-latency: Maximum delay between the signaling of a wake-up event and the
-CPU being able to execute normal code again. If not specified, this is assumed
-to be entry-latency + exit-latency.
-
-These timing parameters can be used by an OS in different circumstances.
-
-An idle CPU requires the expected min-residency time to select the most
-appropriate idle state based on the expected expiry time of the next IRQ
-(i.e. wake-up) that causes the CPU to return to the EXEC phase.
-
-An operating system scheduler may need to compute the shortest wake-up delay
-for CPUs in the system by detecting how long will it take to get a CPU out
-of an idle state, e.g.:
-
-wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
-
-In other words, the scheduler can make its scheduling decision by selecting
-(e.g. waking-up) the CPU with the shortest wake-up delay.
-The wake-up delay must take into account the entry latency if that period
-has not expired. The abortable nature of the PREP period can be ignored
-if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
-the worst case since it depends on the CPU operating conditions, i.e. caches
-state).
-
-An OS has to reliably probe the wakeup-latency since some devices can enforce
-latency constraint guarantees to work properly, so the OS has to detect the
-worst case wake-up latency it can incur if a CPU is allowed to enter an
-idle state, and possibly to prevent that to guarantee reliable device
-functioning.
-
-The min-residency time parameter deserves further explanation since it is
-expressed in time units but must factor in energy consumption coefficients.
-
-The energy consumption of a cpu when it enters a power state can be roughly
-characterised by the following graph:
-
- |
- |
- |
- e |
- n | /---
- e | /------
- r | /------
- g | /-----
- y | /------
- | ----
- | /|
- | / |
- | / |
- | / |
- | / |
- | / |
- |/ |
- -----|-------+----------------------------------
- 0| 1 time(ms)
-
- Graph 1: Energy vs time example
-
-The graph is split in two parts delimited by time 1ms on the X-axis.
-The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
-and denotes the energy costs incurred while entering and leaving the idle
-state.
-The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
-shallower slope and essentially represents the energy consumption of the idle
-state.
-
-min-residency is defined for a given idle state as the minimum expected
-residency time for a state (inclusive of preparation and entry) after
-which choosing that state become the most energy efficient option. A good
-way to visualise this, is by taking the same graph above and comparing some
-states energy consumptions plots.
-
-For sake of simplicity, let's consider a system with two idle states IDLE1,
-and IDLE2:
-
- |
- |
- |
- | /-- IDLE1
- e | /---
- n | /----
- e | /---
- r | /-----/--------- IDLE2
- g | /-------/---------
- y | ------------ /---|
- | / /---- |
- | / /--- |
- | / /---- |
- | / /--- |
- | --- |
- | / |
- | / |
- |/ | time
- ---/----------------------------+------------------------
- |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
- |
- IDLE2-min-residency
-
- Graph 2: idle states min-residency example
-
-In graph 2 above, that takes into account idle states entry/exit energy
-costs, it is clear that if the idle state residency time (i.e. time till next
-wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
-choice energywise.
-
-This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
-than IDLE2.
-
-However, the lower power consumption (i.e. shallower energy curve slope) of
-idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
-efficient.
-
-The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
-shallower states in a system with multiple idle states) is defined
-IDLE2-min-residency and corresponds to the time when energy consumption of
-IDLE1 and IDLE2 states breaks even.
-
-The definitions provided in this section underpin the idle states
-properties specification that is the subject of the following sections.
-
-===========================================
-3 - idle-states node
-===========================================
-
-ARM processor idle states are defined within the idle-states node, which is
-a direct child of the cpus node [1] and provides a container where the
-processor idle states, defined as device tree nodes, are listed.
-
-- idle-states node
-
- Usage: Optional - On ARM systems, it is a container of processor idle
- states nodes. If the system does not provide CPU
- power management capabilities, or the processor just
- supports idle_standby, an idle-states node is not
- required.
-
- Description: idle-states node is a container node, where its
- subnodes describe the CPU idle states.
-
- Node name must be "idle-states".
-
- The idle-states node's parent node must be the cpus node.
-
- The idle-states node's child nodes can be:
-
- - one or more state nodes
-
- Any other configuration is considered invalid.
-
- An idle-states node defines the following properties:
-
- - entry-method
- Value type: <stringlist>
- Usage and definition depend on ARM architecture version.
- # On ARM v8 64-bit this property is required and must
- be:
- - "psci"
- # On ARM 32-bit systems this property is optional
-
-This assumes that the "enable-method" property is set to "psci" in the cpu
-node[6] that is responsible for setting up CPU idle management in the OS
-implementation.
-
-The nodes describing the idle states (state) can only be defined
-within the idle-states node, any other configuration is considered invalid
-and therefore must be ignored.
-
-===========================================
-4 - state node
-===========================================
-
-A state node represents an idle state description and must be defined as
-follows:
-
-- state node
-
- Description: must be child of the idle-states node
-
- The state node name shall follow standard device tree naming
- rules ([5], 2.2.1 "Node names"), in particular state nodes which
- are siblings within a single common parent must be given a unique name.
-
- The idle state entered by executing the wfi instruction (idle_standby
- SBSA,[3][4]) is considered standard on all ARM platforms and therefore
- must not be listed.
-
- With the definitions provided above, the following list represents
- the valid properties for a state node:
-
- - compatible
- Usage: Required
- Value type: <stringlist>
- Definition: Must be "arm,idle-state".
-
- - local-timer-stop
- Usage: See definition
- Value type: <none>
- Definition: if present the CPU local timer control logic is
- lost on state entry, otherwise it is retained.
-
- - entry-latency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing worst case latency in
- microseconds required to enter the idle state.
-
- - exit-latency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing worst case latency
- in microseconds required to exit the idle state.
- The exit-latency-us duration may be guaranteed
- only after entry-latency-us has passed.
-
- - min-residency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing minimum residency duration
- in microseconds, inclusive of preparation and
- entry, for this idle state to be considered
- worthwhile energy wise (refer to section 2 of
- this document for a complete description).
-
- - wakeup-latency-us:
- Usage: Optional
- Value type: <prop-encoded-array>
- Definition: u32 value representing maximum delay between the
- signaling of a wake-up event and the CPU being
- able to execute normal code again. If omitted,
- this is assumed to be equal to:
-
- entry-latency-us + exit-latency-us
-
- It is important to supply this value on systems
- where the duration of PREP phase (see diagram 1,
- section 2) is non-neglibigle.
- In such systems entry-latency-us + exit-latency-us
- will exceed wakeup-latency-us by this duration.
-
- - status:
- Usage: Optional
- Value type: <string>
- Definition: A standard device tree property [5] that indicates
- the operational status of an idle-state.
- If present, it shall be:
- "okay": to indicate that the idle state is
- operational.
- "disabled": to indicate that the idle state has
- been disabled in firmware so it is not
- operational.
- If the property is not present the idle-state must
- be considered operational.
-
- - idle-state-name:
- Usage: Optional
- Value type: <string>
- Definition: A string used as a descriptive name for the idle
- state.
-
- In addition to the properties listed above, a state node may require
- additional properties specific to the entry-method defined in the
- idle-states node. Please refer to the entry-method bindings
- documentation for properties definitions.

+ ==========================================
+ 1 - Introduction
+ ==========================================
+
+ ARM systems contain HW capable of managing power consumption dynamically,
+ where cores can be put in different low-power states (ranging from simple wfi
+ to power gating) according to OS PM policies. The CPU states representing the
+ range of dynamic idle states that a processor can enter at run-time, can be
+ specified through device tree bindings representing the parameters required to
+ enter/exit specific idle states on a given processor.
+
+ According to the Server Base System Architecture document (SBSA, [3]), the
+ power states an ARM CPU can be put into are identified by the following list:
+
+ - Running
+ - Idle_standby
+ - Idle_retention
+ - Sleep
+ - Off
+
+ The power states described in the SBSA document define the basic CPU states on
+ top of which ARM platforms implement power management schemes that allow an OS
+ PM implementation to put the processor in different idle states (which include
+ states listed above; "off" state is not an idle state since it does not have
+ wake-up capabilities, hence it is not considered in this document).
+
+ Idle state parameters (e.g. entry latency) are platform specific and need to
+ be characterized with bindings that provide the required information to OS PM
+ code so that it can build the required tables and use them at runtime.
+
+ The device tree binding definition for ARM idle states is the subject of this
+ document.
+
+ ===========================================
+ 2 - idle-states definitions
+ ===========================================
+
+ Idle states are characterized for a specific system through a set of
+ timing and energy related properties, that underline the HW behaviour
+ triggered upon idle states entry and exit.
+
+ The following diagram depicts the CPU execution phases and related timing
+ properties required to enter and exit an idle state:
+
+ ..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
+ | | | | |
+
+ |<------ entry ------->|
+ | latency |
+ |<- exit ->|
+ | latency |
+ |<-------- min-residency -------->|
+ |<------- wakeup-latency ------->|
+
+ Diagram 1: CPU idle state execution phases
+
+ EXEC: Normal CPU execution.
+
+ PREP: Preparation phase before committing the hardware to idle mode
+ like cache flushing. This is abortable on pending wake-up
+ event conditions. The abort latency is assumed to be negligible
+ (i.e. less than the ENTRY + EXIT duration). If aborted, CPU
+ goes back to EXEC. This phase is optional. If not abortable,
+ this should be included in the ENTRY phase instead.
+
+ ENTRY: The hardware is committed to idle mode. This period must run
+ to completion up to IDLE before anything else can happen.
+
+ IDLE: This is the actual energy-saving idle period. This may last
+ between 0 and infinite time, until a wake-up event occurs.
+
+ EXIT: Period during which the CPU is brought back to operational
+ mode (EXEC).
+
+ entry-latency: Worst case latency required to enter the idle state. The
+ exit-latency may be guaranteed only after entry-latency has passed.
+
+ min-residency: Minimum period, including preparation and entry, for a given
+ idle state to be worthwhile energywise.
+
+ wakeup-latency: Maximum delay between the signaling of a wake-up event and the
+ CPU being able to execute normal code again. If not specified, this is assumed
+ to be entry-latency + exit-latency.
+
+ These timing parameters can be used by an OS in different circumstances.
+
+ An idle CPU requires the expected min-residency time to select the most
+ appropriate idle state based on the expected expiry time of the next IRQ
+ (i.e. wake-up) that causes the CPU to return to the EXEC phase.
+
+ An operating system scheduler may need to compute the shortest wake-up delay
+ for CPUs in the system by detecting how long will it take to get a CPU out
+ of an idle state, e.g.:
+
+ wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
+
+ In other words, the scheduler can make its scheduling decision by selecting
+ (e.g. waking-up) the CPU with the shortest wake-up delay.
+ The wake-up delay must take into account the entry latency if that period
+ has not expired. The abortable nature of the PREP period can be ignored
+ if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
+ the worst case since it depends on the CPU operating conditions, i.e. caches
+ state).
+
+ An OS has to reliably probe the wakeup-latency since some devices can enforce
+ latency constraint guarantees to work properly, so the OS has to detect the
+ worst case wake-up latency it can incur if a CPU is allowed to enter an
+ idle state, and possibly to prevent that to guarantee reliable device
+ functioning.
+
+ The min-residency time parameter deserves further explanation since it is
+ expressed in time units but must factor in energy consumption coefficients.
+
+ The energy consumption of a cpu when it enters a power state can be roughly
+ characterised by the following graph:
+
+ |
+ |
+ |
+ e |
+ n | /---
+ e | /------
+ r | /------
+ g | /-----
+ y | /------
+ | ----
+ | /|
+ | / |
+ | / |
+ | / |
+ | / |
+ | / |
+ |/ |
+ -----|-------+----------------------------------
+ 0| 1 time(ms)
+
+ Graph 1: Energy vs time example
+
+ The graph is split in two parts delimited by time 1ms on the X-axis.
+ The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
+ and denotes the energy costs incurred while entering and leaving the idle
+ state.
+ The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
+ shallower slope and essentially represents the energy consumption of the idle
+ state.
+
+ min-residency is defined for a given idle state as the minimum expected
+ residency time for a state (inclusive of preparation and entry) after
+ which choosing that state become the most energy efficient option. A good
+ way to visualise this, is by taking the same graph above and comparing some
+ states energy consumptions plots.
+
+ For sake of simplicity, let's consider a system with two idle states IDLE1,
+ and IDLE2:
+
+ |
+ |
+ |
+ | /-- IDLE1
+ e | /---
+ n | /----
+ e | /---
+ r | /-----/--------- IDLE2
+ g | /-------/---------
+ y | ------------ /---|
+ | / /---- |
+ | / /--- |
+ | / /---- |
+ | / /--- |
+ | --- |
+ | / |
+ | / |
+ |/ | time
+ ---/----------------------------+------------------------
+ |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
+ |
+ IDLE2-min-residency
+
+ Graph 2: idle states min-residency example
+
+ In graph 2 above, that takes into account idle states entry/exit energy
+ costs, it is clear that if the idle state residency time (i.e. time till next
+ wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
+ choice energywise.
+
+ This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
+ than IDLE2.
+
+ However, the lower power consumption (i.e. shallower energy curve slope) of
+ idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
+ efficient.
+
+ The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
+ shallower states in a system with multiple idle states) is defined
+ IDLE2-min-residency and corresponds to the time when energy consumption of
+ IDLE1 and IDLE2 states breaks even.
+
+ The definitions provided in this section underpin the idle states
+ properties specification that is the subject of the following sections.
+
+ ===========================================
+ 3 - idle-states node
+ ===========================================
+
+ ARM processor idle states are defined within the idle-states node, which is
+ a direct child of the cpus node [1] and provides a container where the
+ processor idle states, defined as device tree nodes, are listed.
+
+ On ARM systems, it is a container of processor idle states nodes. If the
+ system does not provide CPU power management capabilities, or the processor
+ just supports idle_standby, an idle-states node is not required.

+ The number of cells in a PM domain specifier as per binding in [3].

+
+ ARM systems can have multiple cores, sometimes in an hierarchical
+ arrangement. This often, but not always, maps directly to the processor
+ power topology of the system. Individual nodes in a topology have their
+ own specific power states and can be better represented hierarchically.
+
+ For these cases, the definitions of the idle states for the CPUs and the
+ CPU topology, must conform to the binding in [3]. The idle states
+ themselves must conform to the binding in [4] and must specify the
+ arm,psci-suspend-param property.
+
+ It should also be noted that, in PSCI firmware v1.0 the OS-Initiated
+ (OSI) CPU suspend mode is introduced. Using a hierarchical representation
+ helps to implement support for OSI mode and OS implementations may choose
+ to mandate it.

-* Faraday Technology FTIDE010 PATA controller
-
-This controller is the first Faraday IDE interface block, used in the

-The timing properties are unique per-SoC, not per-board.
-
-Required properties:
-- compatible: should be one of

- "faraday,ftide010"
-- interrupts: interrupt for the block
-- reg: registers and size for the block
-
-Optional properties:
-- clocks: a SoC clock running the peripheral.
-- clock-names: should be set to "PCLK" for the peripheral clock.
-
-Required properties for "cortina,gemini-pata" compatible:

+description: |
+ It is possible to use the BCLK pin of a SAI module as a generic clock
+ output. Some SoC are very constrained in their pin multiplexer
+ configuration. Eg. pins can only be changed groups. For example, on the
+ LS1028A SoC you can only enable SAIs in pairs. If you use only one SAI,
+ the second pins are wasted. Using this binding it is possible to use the
+ clock of the second SAI as a MCLK clock for an audio codec, for example.
+
+ This is a composite of a gated clock and a divider clock.

-STMicroelectronics STM32 Peripheral Reset Clock Controller
-==========================================================
-
-The RCC IP is both a reset and a clock controller.
-
-RCC makes also power management (resume/supend and wakeup interrupt).
-
-Please also refer to reset.txt for common reset controller binding usage.
-
-Please also refer to clock-bindings.txt for common clock controller
-binding usage.
-
-
-Required properties:
-- compatible: "st,stm32mp1-rcc", "syscon"
-- reg: should be register base and length as documented in the datasheet
-- #clock-cells: 1, device nodes should specify the clock in their
- "clocks" property, containing a phandle to the clock device node,
- an index specifying the clock to use.
-- #reset-cells: Shall be 1
-- interrupts: Should contain a general interrupt line and a interrupt line
- to the wake-up of processor (CSTOP).
-
-Example:
- rcc: rcc@50000000 {
- compatible = "st,stm32mp1-rcc", "syscon";
- reg = <0x50000000 0x1000>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- interrupts = <GIC_SPI 5 IRQ_TYPE_NONE>,
- <GIC_SPI 145 IRQ_TYPE_NONE>;
- };
-
-Specifying clocks
-=================
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/stm32mp1-clks.h header and can be used in device
-tree sources.
-
-Specifying softreset control of devices
-=======================================
-
-Device nodes should specify the reset channel required in their "resets"
-property, containing a phandle to the reset device node and an index specifying
-which channel to use.
-The index is the bit number within the RCC registers bank, starting from RCC
-base address.
-It is calculated as: index = register_offset / 4 * 32 + bit_offset.
-Where bit_offset is the bit offset within the register.
-
-For example on STM32MP1, for LTDC reset:
- ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset
- = 0x180 / 4 * 32 + 0 = 3072
-
-The list of valid indices for STM32MP1 is available in:
-include/dt-bindings/reset-controller/stm32mp1-resets.h
-
-This file implements defines like:
-#define LTDC_R 3072

-Required properties for all clocks:
-- reg : shall be the control register address for the clock.
-- clocks : shall be the input parent clock(s) phandle for the clock. For
- multiplexed clocks, the list order must match the hardware
- programming order.
-- #clock-cells : from common clock binding; shall be set to 0 except for
- the following compatibles where it shall be set to 1:
- "allwinner,*-gates-clk", "allwinner,sun4i-pll5-clk",
- "allwinner,sun4i-pll6-clk", "allwinner,sun6i-a31-pll6-clk",
- "allwinner,*-usb-clk", "allwinner,*-mmc-clk",
- "allwinner,*-mmc-config-clk"
-- clock-output-names : shall be the corresponding names of the outputs.
- If the clock module only has one output, the name shall be the
- module name.
-
-And "allwinner,*-usb-clk" clocks also require:
-- reset-cells : shall be set to 1
-
-The "allwinner,sun4i-a10-ve-clk" clock also requires:
-- reset-cells : shall be set to 0
-
-The "allwinner,sun9i-a80-mmc-config-clk" clock also requires:
-- #reset-cells : shall be set to 1
-- resets : shall be the reset control phandle for the mmc block.
-
-For "allwinner,sun7i-a20-gmac-clk", the parent clocks shall be fixed rate
-dummy clocks at 25 MHz and 125 MHz, respectively. See example.
-
-Clock consumers should specify the desired clocks they use with a
-"clocks" phandle cell. Consumers that are using a gated clock should
-provide an additional ID in their clock property. This ID is the
-offset of the bit controlling this particular gate in the register.
-For the other clocks with "#clock-cells" = 1, the additional ID shall
-refer to the index of the output.
-
-For "allwinner,sun6i-a31-pll6-clk", there are 2 outputs. The first output
-is the normal PLL6 output, or "pll6". The second output is rate doubled
-PLL6, or "pll6x2".
-
-The "allwinner,*-mmc-clk" clocks have three different outputs: the
-main clock, with the ID 0, and the output and sample clocks, with the
-IDs 1 and 2, respectively.
-
-The "allwinner,sun9i-a80-mmc-config-clk" clock has one clock/reset output
-per mmc controller. The number of outputs is determined by the size of
-the address block, which is related to the overall mmc block.

+
+description: |
+ The display engine pipeline (and its entry point, since it can be
+ either directly the backend or the frontend) is represented as an
+ extra node.
+
+ The Allwinner A10 Display pipeline is composed of several components
+ that are going to be documented below:
+
+ For all connections between components up to the TCONs in the
+ display pipeline, when there are multiple components of the same
+ type at the same depth, the local endpoint ID must be the same as
+ the remote component's index. For example, if the remote endpoint is
+ Frontend 1, then the local endpoint ID must be 1.
+
+ Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
+ [1] -- -- [1] [1] -- -- [1]
+ \ / \ /
+ X X
+ / \ / \
+ [0] -- -- [0] [0] -- -- [0]
+ Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
+
+ For a two pipeline system such as the one depicted above, the lines
+ represent the connections between the components, while the numbers
+ within the square brackets corresponds to the ID of the local endpoint.
+
+ The same rule also applies to DE 2.0 mixer-TCON connections:
+
+ Mixer 0 [0] ----------- [0] TCON 0
+ [1] ---- ---- [1]
+ \ /
+ X
+ / \
+ [0] ---- ---- [0]
+ Mixer 1 [1] ----------- [1] TCON 1

+description: |
+ TCON TOPs main purpose is to configure whole display pipeline. It
+ determines relationships between mixers and TCONs, selects source
+ TCON for HDMI, muxes LCD and TV encoder GPIO output, selects TV
+ encoder clock source and contains additional TV TCON and DSI gates.
+
+ It allows display pipeline to be configured in very different ways:
+
+ / LCD0/LVDS0
+ / [0] TCON-LCD0
+ | \ MIPI DSI
+ mixer0 |
+ \ / [1] TCON-LCD1 - LCD1/LVDS1
+ TCON-TOP
+ / \ [2] TCON-TV0 [0] - TVE0/RGB
+ mixer1 | \
+ | TCON-TOP - HDMI
+ | /
+ \ [3] TCON-TV1 [1] - TVE1/RGB
+
+ Note that both TCON TOP references same physical unit. Both mixers
+ can be connected to any TCON. Not all TCON TOP variants support all
+ features.

+title: Common Properties for DSI Display Panels
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ This document defines device tree properties common to DSI, Display
+ Serial Interface controllers and attached panels. It doesn't constitute
+ a device tree binding specification by itself but is meant to be referenced
+ by device tree bindings.
+
+ When referenced from panel device tree bindings the properties defined in
+ this document are defined as follows. The panel device tree bindings are
+ responsible for defining whether each property is required or optional.
+
+ Notice: this binding concerns DSI panels connected directly to a master
+ without any intermediate port graph to the panel. Each DSI master
+ can control one to four virtual channels to one panel. Each virtual
+ channel should have a node "panel" for their virtual channel with their
+ reg-property set to the virtual channel number, usually there is just
+ one virtual channel, number 0.
+
+properties:
+ $nodename:
+ pattern: "^dsi-controller(@.*)?$"
+
+ "#address-cells":
+ const: 1
+
+ "#size-cells":

+ description: Panels connected to the DSI link
+ type: object
+
+ properties:
+ reg:
+ minimum: 0
+ maximum: 3
+ description:
+ The virtual channel number of a DSI peripheral. Must be in the range
+ from 0 to 3, as DSI uses a 2-bit addressing scheme. Some DSI
+ peripherals respond to more than a single virtual channel. In that
+ case the reg property can take multiple entries, one for each virtual
+ channel that the peripheral responds to.
+
+ clock-master:
+ type: boolean
+ description:
+ Should be enabled if the host is being used in conjunction with
+ another DSI host to drive the same peripheral. Hardware supporting
+ such a configuration generally requires the data on both the busses
+ to be driven by the same clock. Only the DSI host instance
+ controlling this clock should contain this property.
+
+ enforce-video-mode:
+ type: boolean
+ description:
+ The best option is usually to run a panel in command mode, as this
+ gives better control over the panel hardware. However for different
+ reasons like broken hardware, missing features or testing, it may be
+ useful to be able to force a command mode-capable panel into video
+ mode.

-Allwinner A10 Display Pipeline
-==============================
-
-The Allwinner A10 Display pipeline is composed of several components
-that are going to be documented below:
-
-For all connections between components up to the TCONs in the display
-pipeline, when there are multiple components of the same type at the
-same depth, the local endpoint ID must be the same as the remote
-component's index. For example, if the remote endpoint is Frontend 1,
-then the local endpoint ID must be 1.
-
- Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
- [1] -- -- [1] [1] -- -- [1]
- \ / \ /
- X X
- / \ / \
- [0] -- -- [0] [0] -- -- [0]
- Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
-
-For a two pipeline system such as the one depicted above, the lines
-represent the connections between the components, while the numbers
-within the square brackets corresponds to the ID of the local endpoint.
-
-The same rule also applies to DE 2.0 mixer-TCON connections:
-
- Mixer 0 [0] ----------- [0] TCON 0
- [1] ---- ---- [1]
- \ /
- X
- / \
- [0] ---- ---- [0]

- require another controller (TV Encoder, HDMI, etc.). The endpoints
- will take an extra property, allwinner,tcon-channel, to specify the
- channel the endpoint is associated to. If that property is not
- present, the endpoint number will be used as the channel number.
-
-For TCONs with channel 0, there is one more clock required:
- - 'tcon-ch0': The clock driving the TCON channel 0
-For TCONs with channel 1, there is one more clock required:
- - 'tcon-ch1': The clock driving the TCON channel 1
-
-When TCON support LVDS (all TCONs except TV TCONs on A83T, R40 and those found
-in A13, H3, H5 and V3s SoCs), you need one more reset line:
- - 'lvds': The reset line driving the LVDS logic
-
-And on the A23, A31, A31s and A33, you need one more clock line:
- - 'lvds-alt': An alternative clock source, separate from the TCON channel 0
- clock, that can be used to drive the LVDS clock
-
-TCON TOP
---------
-
-TCON TOPs main purpose is to configure whole display pipeline. It determines
-relationships between mixers and TCONs, selects source TCON for HDMI, muxes
-LCD and TV encoder GPIO output, selects TV encoder clock source and contains
-additional TV TCON and DSI gates.
-
-It allows display pipeline to be configured in very different ways:
-
- / LCD0/LVDS0
- / [0] TCON-LCD0
- | \ MIPI DSI
- mixer0 |
- \ / [1] TCON-LCD1 - LCD1/LVDS1
- TCON-TOP
- / \ [2] TCON-TV0 [0] - TVE0/RGB
- mixer1 | \
- | TCON-TOP - HDMI
- | /
- \ [3] TCON-TV1 [1] - TVE1/RGB
-
-Note that both TCON TOP references same physical unit. Both mixers can be
-connected to any TCON. Not all TCON TOP variants support all features.
-

-* STMicroelectronics STM32 DMA controller
-
-The STM32 DMA is a general-purpose direct memory access controller capable of
-supporting 8 independent DMA channels. Each channel can have up to 8 requests.
-
-Required properties:
-- compatible: Should be "st,stm32-dma"
-- reg: Should contain DMA registers location and length. This should include
- all of the per-channel registers.
-- interrupts: Should contain all of the per-channel DMA interrupts in
- ascending order with respect to the DMA channel index.
-- clocks: Should contain the input clock of the DMA instance.
-- #dma-cells : Must be <4>. See DMA client paragraph for more details.
-
-Optional properties:
-- dma-requests : Number of DMA requests supported.
-- resets: Reference to a reset controller asserting the DMA controller
-- st,mem2mem: boolean; if defined, it indicates that the controller supports
- memory-to-memory transfer

-STMicroelectronics STM32 DFSDM ADC device driver
-
-
-STM32 DFSDM ADC is a sigma delta analog-to-digital converter dedicated to
-interface external sigma delta modulators to STM32 micro controllers.
-It is mainly targeted for:
-- Sigma delta modulators (motor control, metering...)
-- PDM microphones (audio digital microphone)
-
-It features up to 8 serial digital interfaces (SPI or Manchester) and
-up to 4 filters on stm32h7 or 6 filters on stm32mp1.
-
-Each child node match with a filter instance.
-
-Contents of a STM32 DFSDM root node:
-------------------------------------
-Required properties:
-- compatible: Should be one of:
- "st,stm32h7-dfsdm"
- "st,stm32mp1-dfsdm"
-- reg: Offset and length of the DFSDM block register set.
-- clocks: IP and serial interfaces clocking. Should be set according
- to rcc clock ID and "clock-names".
-- clock-names: Input clock name "dfsdm" must be defined,
- "audio" is optional. If defined CLKOUT is based on the audio
- clock, else "dfsdm" is used.
-- #interrupt-cells = <1>;
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- spi-max-frequency: Requested only for SPI master mode.
- SPI clock OUT frequency (Hz). This clock must be set according
- to "clock" property. Frequency must be a multiple of the rcc
- clock frequency. If not, SPI CLKOUT frequency will not be
- accurate.
-- pinctrl-names: Set to "default".
-- pinctrl-0: List of phandles pointing to pin configuration
- nodes to set pins in mode of operation for dfsdm
- on external pin.
-
-Contents of a STM32 DFSDM child nodes:
---------------------------------------
-
-Required properties:
-- compatible: Must be:
- "st,stm32-dfsdm-adc" for sigma delta ADCs
- "st,stm32-dfsdm-dmic" for audio digital microphone.
-- reg: Specifies the DFSDM filter instance used.
- Valid values are from 0 to 3 on stm32h7, 0 to 5 on stm32mp1.
-- interrupts: IRQ lines connected to each DFSDM filter instance.
-- st,adc-channels: List of single-ended channels muxed for this ADC.
- valid values:
- "st,stm32h7-dfsdm" compatibility: 0 to 7.
-- st,adc-channel-names: List of single-ended channel names.
-- st,filter-order: SinC filter order from 0 to 5.
- 0: FastSinC
- [1-5]: order 1 to 5.
- For audio purpose it is recommended to use order 3 to 5.
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers".
-
-Required properties for "st,stm32-dfsdm-adc" compatibility:
-- io-channels: From common IIO binding. Used to pipe external sigma delta
- modulator or internal ADC output to DFSDM channel.
- This is not required for "st,stm32-dfsdm-pdm" compatibility as
- PDM microphone is binded in Audio DT node.
-
-Required properties for "st,stm32-dfsdm-pdm" compatibility:
-- #sound-dai-cells: Must be set to 0.
-- dma: DMA controller phandle and DMA request line associated to the
- filter instance (specified by the field "reg")
-- dma-names: Must be "rx"
-
-Optional properties:
-- st,adc-channel-types: Single-ended channel input type.
- - "SPI_R": SPI with data on rising edge (default)
- - "SPI_F": SPI with data on falling edge
- - "MANCH_R": manchester codec, rising edge = logic 0, falling edge = logic 1
- - "MANCH_F": manchester codec, rising edge = logic 1, falling edge = logic 0
-- st,adc-channel-clk-src: Conversion clock source.
- - "CLKIN": external SPI clock (CLKIN x)
- - "CLKOUT": internal SPI clock (CLKOUT) (default)
- - "CLKOUT_F": internal SPI clock divided by 2 (falling edge).
- - "CLKOUT_R": internal SPI clock divided by 2 (rising edge).
-
-- st,adc-alt-channel: Must be defined if two sigma delta modulator are
- connected on same SPI input.
- If not set, channel n is connected to SPI input n.
- If set, channel n is connected to SPI input n + 1.
-
-- st,filter0-sync: Set to 1 to synchronize with DFSDM filter instance 0.
- Used for multi microphones synchronization.
-
-Example of a sigma delta adc connected on DFSDM SPI port 0
-and a pdm microphone connected on DFSDM SPI port 1:
-

+description: |
+ STM32 DFSDM ADC is a sigma delta analog-to-digital converter dedicated to
+ interface external sigma delta modulators to STM32 micro controllers.
+ It is mainly targeted for:
+ - Sigma delta modulators (motor control, metering...)
+ - PDM microphones (audio digital microphone)
+
+ It features up to 8 serial digital interfaces (SPI or Manchester) and
+ up to 4 filters on stm32h7 or 6 filters on stm32mp1.
+
+ Each child node matches with a filter instance.

-* Common leds properties.
-
-LED and flash LED devices provide the same basic functionality as current
-regulators, but extended with LED and flash LED specific features like
-blinking patterns, flash timeout, flash faults and external flash strobe mode.
-
-Many LED devices expose more than one current output that can be connected
-to one or more discrete LED component. Since the arrangement of connections
-can influence the way of the LED device initialization, the LED components
-have to be tightly coupled with the LED device binding. They are represented
-by child nodes of the parent LED device binding.
-
-
-Optional properties for child nodes:
-- led-sources : List of device current outputs the LED is connected to. The
- outputs are identified by the numbers that must be defined
- in the LED device binding documentation.
-
-- function: LED functon. Use one of the LED_FUNCTION_* prefixed definitions
- from the header include/dt-bindings/leds/common.h.
- If there is no matching LED_FUNCTION available, add a new one.
-
-- color : Color of the LED. Use one of the LED_COLOR_ID_* prefixed definitions
- from the header include/dt-bindings/leds/common.h.
- If there is no matching LED_COLOR_ID available, add a new one.
-
-- function-enumerator: Integer to be used when more than one instance
- of the same function is needed, differing only with
- an ordinal number.
-
-- label : The label for this LED. If omitted, the label is taken from the node
- name (excluding the unit address). It has to uniquely identify
- a device, i.e. no other LED class device can be assigned the same
- label. This property is deprecated - use 'function' and 'color'
- properties instead. function-enumerator has no effect when this
- property is present.
-
-- default-state : The initial state of the LED. Valid values are "on", "off",
- and "keep". If the LED is already on or off and the default-state property is
- set the to same value, then no glitch should be produced where the LED
- momentarily turns off (or on). The "keep" setting will keep the LED at
- whatever its current state is, without producing a glitch. The default is
- off if this property is not present.
-
-- linux,default-trigger : This parameter, if present, is a
- string defining the trigger assigned to the LED. Current triggers are:
- "backlight" - LED will act as a back-light, controlled by the framebuffer
- system
- "default-on" - LED will turn on (but for leds-gpio see "default-state"
- property in Documentation/devicetree/bindings/leds/leds-gpio.txt)
- "heartbeat" - LED "double" flashes at a load average based rate
- "disk-activity" - LED indicates disk activity
- "ide-disk" - LED indicates IDE disk activity (deprecated),
- in new implementations use "disk-activity"
- "timer" - LED flashes at a fixed, configurable rate
- "pattern" - LED alters the brightness for the specified duration with one
- software timer (requires "led-pattern" property)
-
-- led-pattern : Array of integers with default pattern for certain triggers.
- Each trigger may parse this property differently:
- - one-shot : two numbers specifying delay on and delay off (in ms),
- - timer : two numbers specifying delay on and delay off (in ms),
- - pattern : the pattern is given by a series of tuples, of
- brightness and duration (in ms). The exact format is
- described in:
- Documentation/devicetree/bindings/leds/leds-trigger-pattern.txt
-
-
-- led-max-microamp : Maximum LED supply current in microamperes. This property
- can be made mandatory for the board configurations
- introducing a risk of hardware damage in case an excessive
- current is set.
- For flash LED controllers with configurable current this
- property is mandatory for the LEDs in the non-flash modes
- (e.g. torch or indicator).
-
-- panic-indicator : This property specifies that the LED should be used,
- if at all possible, as a panic indicator.
-
-- trigger-sources : List of devices which should be used as a source triggering
- this LED activity. Some LEDs can be related to a specific
- device and should somehow indicate its state. E.g. USB 2.0
- LED may react to device(s) in a USB 2.0 port(s).
- Another common example is switch or router with multiple
- Ethernet ports each of them having its own LED assigned
- (assuming they are not hardwired). In such cases this
- property should contain phandle(s) of related source
- device(s).
- In many cases LED can be related to more than one device
- (e.g. one USB LED vs. multiple USB ports). Each source
- should be represented by a node in the device tree and be
- referenced by a phandle and a set of phandle arguments. A
- length of arguments should be specified by the
- #trigger-source-cells property in the source node.
-
-Required properties for flash LED child nodes:
-- flash-max-microamp : Maximum flash LED supply current in microamperes.
-- flash-max-timeout-us : Maximum timeout in microseconds after which the flash
- LED is turned off.
-
-For controllers that have no configurable current the flash-max-microamp
-property can be omitted.
-For controllers that have no configurable timeout the flash-max-timeout-us
-property can be omitted.
-
-* Trigger source providers
-
-Each trigger source should be represented by a device tree node. It may be e.g.
-a USB port or an Ethernet device.
-
-Required properties for trigger source:
-- #trigger-source-cells : Number of cells in a source trigger. Typically 0 for
- nodes of simple trigger sources (e.g. a specific USB
- port).
-
-* Examples
-
-#include <dt-bindings/leds/common.h>

-except for the hardware bitstream parser that makes use of an undocumented
-region.
-
-It makes use of the following blocks:
-
-- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
-then feed from this VIFIFO.
-- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
-- VDEC_HEVC can decode HEVC and VP9.

- - GXBB (S905) : "amlogic,gxbb-vdec"
- - GXL (S905X, S905D) : "amlogic,gxl-vdec"
- - GXM (S912) : "amlogic,gxm-vdec"
- followed by the common "amlogic,gx-vdec"
-- reg: base address and size of he following memory-mapped regions :
- - dos
- - esparser
-- reg-names: should contain the names of the previous memory regions
-- interrupts: should contain the following IRQs:
- - vdec
- - esparser
-- interrupt-names: should contain the names of the previous interrupts
-- amlogic,ao-sysctrl: should point to the AOBUS sysctrl node
-- amlogic,canvas: should point to a canvas provider node
-- clocks: should contain the following clocks :
- - dos_parser
- - dos
- - vdec_1
- - vdec_hevc
-- clock-names: should contain the names of the previous clocks
-- resets: should contain the parser reset
-- reset-names: should be "esparser"

+
+description: |
+ The NVIDIA Tegra186 SoC features a 128 bit memory controller that is split
+ into four 32 bit channels to support LPDDR4 with x16 subpartitions. The MC
+ handles memory requests for 40-bit virtual addresses from internal clients
+ and arbitrates among them to allocate memory bandwidth.
+
+ Up to 15 GiB of physical memory can be supported. Security features such as
+ encryption of traffic to and from DRAM via general security apertures are
+ available for video and other secure applications, as well as DRAM ECC for
+ automotive safety applications (single bit error correction and double bit
+ error detection).

-Allwinner Technologies, Inc. NVMEM CPUFreq and OPP bindings
-===================================
-
-For some SoCs, the CPU frequency subset and voltage value of each OPP
-varies based on the silicon variant in use. Allwinner Process Voltage
-Scaling Tables defines the voltage and frequency value based on the
-speedbin blown in the efuse combination. The sun50i-cpufreq-nvmem driver
-reads the efuse value from the SoC to provide the OPP framework with
-required information.
-
-Required properties:
---------------------
-In 'cpus' nodes:
-- operating-points-v2: Phandle to the operating-points-v2 table to use.
-
-In 'operating-points-v2' table:
-- compatible: Should be
- - 'allwinner,sun50i-h6-operating-points'.
-- nvmem-cells: A phandle pointing to a nvmem-cells node representing the
- efuse registers that has information about the speedbin
- that is used to select the right frequency/voltage value
- pair. Please refer the for nvmem-cells bindings
- Documentation/devicetree/bindings/nvmem/nvmem.txt and
- also examples below.
-
-In every OPP node:
-- opp-microvolt-<name>: Voltage in micro Volts.
- At runtime, the platform can pick a <name> and
- matching opp-microvolt-<name> property.
- [See: opp.txt]
- HW: <name>:

-* Synopsys DesignWare PCIe root complex in ECAM shift mode
-
-In some cases, firmware may already have configured the Synopsys DesignWare
-PCIe controller in RC mode with static ATU window mappings that cover all
-config, MMIO and I/O spaces in a [mostly] ECAM compatible fashion.
-In this case, there is no need for the OS to perform any low level setup
-of clocks, PHYs or device registers, nor is there any reason for the driver
-to reconfigure ATU windows for config and/or IO space accesses at runtime.
-
-In cases where the IP was synthesized with a minimum ATU window size of
-64 KB, it cannot be supported by the generic ECAM driver, because it
-requires special config space accessors that filter accesses to device #1
-and beyond on the first bus.
-
-Required properties:
-- compatible: "marvell,armada8k-pcie-ecam" or
- "socionext,synquacer-pcie-ecam" or
- "snps,dw-pcie-ecam" (must be preceded by a more specific match)
-
-Please refer to the binding document of "pci-host-ecam-generic" in the
-file host-generic-pci.txt for a description of the remaining required
-and optional properties.
-

-
- pcie1: pcie@7f000000 {

-* Generic PCI host controller
-
-Firmware-initialised PCI host controllers and PCI emulations, such as the
-virtio-pci implementations found in kvmtool and other para-virtualised
-systems, do not require driver support for complexities such as regulator
-and clock management. In fact, the controller may not even require the
-configuration of a control interface by the operating system, instead
-presenting a set of fixed windows describing a subset of IO, Memory and
-Configuration Spaces.
-
-Such a controller can be described purely in terms of the standardized device
-tree bindings communicated in pci.txt:
-
-
-Properties of the host controller node:
-
-- compatible : Must be "pci-host-cam-generic" or "pci-host-ecam-generic"
- depending on the layout of configuration space (CAM vs
- ECAM respectively).
-
-- device_type : Must be "pci".
-
-- ranges : As described in IEEE Std 1275-1994, but must provide
- at least a definition of non-prefetchable memory. One
- or both of prefetchable Memory and IO Space may also
- be provided.
-
-- bus-range : Optional property (also described in IEEE Std 1275-1994)
- to indicate the range of bus numbers for this controller.
- If absent, defaults to <0 255> (i.e. all buses).
-
-- #address-cells : Must be 3.
-
-- #size-cells : Must be 2.
-
-- reg : The Configuration Space base address and size, as accessed
- from the parent bus. The base address corresponds to
- the first bus in the "bus-range" property. If no
- "bus-range" is specified, this will be bus 0 (the default).
-
-Properties of the /chosen node:
-
-- linux,pci-probe-only
- : Optional property which takes a single-cell argument.
- If '0', then Linux will assign devices in its usual manner,
- otherwise it will not try to assign devices and instead use
- them as they are configured already.
-
-Configuration Space is assumed to be memory-mapped (as opposed to being
-accessed via an ioport) and laid out with a direct correspondence to the
-geography of a PCI bus address by concatenating the various components to
-form an offset.
-
-For CAM, this 24-bit offset is:
-
- cfg_offset(bus, device, function, register) =
- bus << 16 | device << 11 | function << 8 | register
-
-While ECAM extends this by 4 bits to accommodate 4k of function space:
-
- cfg_offset(bus, device, function, register) =
- bus << 20 | device << 15 | function << 12 | register
-
-Interrupt mapping is exactly as described in `Open Firmware Recommended
-Practice: Interrupt Mapping' and requires the following properties:
-
-- #interrupt-cells : Must be 1
-
-- interrupt-map : <see aforementioned specification>
-
-- interrupt-map-mask : <see aforementioned specification>
-
-
-Example:
-
-pci {
- compatible = "pci-host-cam-generic"
- device_type = "pci";
- #address-cells = <3>;
- #size-cells = <2>;
- bus-range = <0x0 0x1>;
-
- // CPU_PHYSICAL(2) SIZE(2)
- reg = <0x0 0x40000000 0x0 0x1000000>;
-
- // BUS_ADDRESS(3) CPU_PHYSICAL(2) SIZE(2)
- ranges = <0x01000000 0x0 0x01000000 0x0 0x01000000 0x0 0x00010000>,
- <0x02000000 0x0 0x41000000 0x0 0x41000000 0x0 0x3f000000>;
-
-
- #interrupt-cells = <0x1>;
-
- // PCI_DEVICE(3) INT#(1) CONTROLLER(PHANDLE) CONTROLLER_DATA(3)
- interrupt-map = < 0x0 0x0 0x0 0x1 &gic 0x0 0x4 0x1
- 0x800 0x0 0x0 0x1 &gic 0x0 0x5 0x1

- 0x1800 0x0 0x0 0x1 &gic 0x0 0x7 0x1>;
-

-Allwinnner SoC SRAM controllers
------------------------------------------------------
-
-The SRAM controller found on most Allwinner devices is represented by
-a regular node for the SRAM controller itself, with sub-nodes
-reprensenting the SRAM handled by the SRAM controller.

-SRAM nodes
-----------
-
-Each SRAM is described using the mmio-sram bindings documented in
-Documentation/devicetree/bindings/sram/sram.txt
-
-Each SRAM will have SRAM sections that are going to be handled by the
-SRAM controller as subnodes. These sections are represented following
-once again the representation described in the mmio-sram binding.
-
-The valid sections compatible for A10 are:
- - allwinner,sun4i-a10-sram-a3-a4
- - allwinner,sun4i-a10-sram-c1
- - allwinner,sun4i-a10-sram-d

-
-The valid sections compatible for A23/A33 are:

-
-The valid sections compatible for F1C100s are:
- - allwinner,suniv-f1c100s-sram-d, allwinner,sun4i-a10-sram-d
-
-Devices using SRAM sections
----------------------------
-
-Some devices need to request to the SRAM controller to map an SRAM for
-their exclusive use.
-
-The relationship between such a device and an SRAM section is
-expressed through the allwinner,sram property, that will take a
-phandle and an argument.
-
-This valid values for this argument are:
- - 0: CPU
- - 1: Device

+How to help improve kernel documentation
+========================================
+
+Documentation is an important part of any software-development project.
+Good documentation helps to bring new developers in and helps established
+developers work more effectively. Without top-quality documentation, a lot
+of time is wasted in reverse-engineering the code and making avoidable
+mistakes.
+
+Unfortunately, the kernel's documentation currently falls far short of what
+it needs to be to support a project of this size and importance.
+
+This guide is for contributors who would like to improve that situation.
+Kernel documentation improvements can be made by developers at a variety of
+skill levels; they are a relatively easy way to learn the kernel process in
+general and find a place in the community. The bulk of what follows is the
+documentation maintainer's list of tasks that most urgently need to be
+done.
+
+The documentation TODO list
+---------------------------
+
+There is an endless list of tasks that need to be carried out to get our
+documentation to where it should be. This list contains a number of
+important items, but is far from exhaustive; if you see a different way to
+improve the documentation, please do not hold back!
+
+Addressing warnings
+~~~~~~~~~~~~~~~~~~~
+
+The documentation build currently spews out an unbelievable number of
+warnings. When you have that many, you might as well have none at all;
+people ignore them, and they will never notice when their work adds new
+ones. For this reason, eliminating warnings is one of the highest-priority
+tasks on the documentation TODO list. The task itself is reasonably
+straightforward, but it must be approached in the right way to be
+successful.
+
+Warnings issued by a compiler for C code can often be dismissed as false
+positives, leading to patches aimed at simply shutting the compiler up.
+Warnings from the documentation build almost always point at a real
+problem; making those warnings go away requires understanding the problem
+and fixing it at its source. For this reason, patches fixing documentation
+warnings should probably not say "fix a warning" in the changelog title;
+they should indicate the real problem that has been fixed.
+
+Another important point is that documentation warnings are often created by
+problems in kerneldoc comments in C code. While the documentation
+maintainer appreciates being copied on fixes for these warnings, the
+documentation tree is often not the right one to actually carry those
+fixes; they should go to the maintainer of the subsystem in question.
+
+For example, in a documentation build I grabbed a pair of warnings nearly
+at random::
+
+ ./drivers/devfreq/devfreq.c:1818: warning: bad line:
+ - Resource-managed devfreq_register_notifier()
+ ./drivers/devfreq/devfreq.c:1854: warning: bad line:
+ - Resource-managed devfreq_unregister_notifier()
+
+(The lines were split for readability).
+
+A quick look at the source file named above turned up a couple of kerneldoc
+comments that look like this::
+
+ /**
+ * devm_devfreq_register_notifier()
+ - Resource-managed devfreq_register_notifier()
+ * @dev: The devfreq user device. (parent of devfreq)
+ * @devfreq: The devfreq object.
+ * @nb: The notifier block to be unregistered.
+ * @list: DEVFREQ_TRANSITION_NOTIFIER.
+ */
+
+The problem is the missing "*", which confuses the build system's
+simplistic idea of what C comment blocks look like. This problem had been
+present since that comment was added in 2016 — a full four years. Fixing
+it was a matter of adding the missing asterisks. A quick look at the
+history for that file showed what the normal format for subject lines is,
+and ``scripts/get_maintainer.pl`` told me who should receive it. The
+resulting patch looked like this::
+
+ [PATCH] PM / devfreq: Fix two malformed kerneldoc comments
+
+ Two kerneldoc comments in devfreq.c fail to adhere to the required format,
+ resulting in these doc-build warnings:
+
+ ./drivers/devfreq/devfreq.c:1818: warning: bad line:
+ - Resource-managed devfreq_register_notifier()
+ ./drivers/devfreq/devfreq.c:1854: warning: bad line:
+ - Resource-managed devfreq_unregister_notifier()
+
+ Add a couple of missing asterisks and make kerneldoc a little happier.

+ 2.24.1
+
+The entire process only took a few minutes. Of course, I then found that
+somebody else had fixed it in a separate tree, highlighting another lesson:
+always check linux-next to see if a problem has been fixed before you dig
+into it.
+
+Other fixes will take longer, especially those relating to structure
+members or function parameters that lack documentation. In such cases, it
+is necessary to work out what the role of those members or parameters is
+and describe them correctly. Overall, this task gets a little tedious at
+times, but it's highly important. If we can actually eliminate warnings
+from the documentation build, then we can start expecting developers to
+avoid adding new ones.
+
+Languishing kerneldoc comments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Developers are encouraged to write kerneldoc comments for their code, but
+many of those comments are never pulled into the docs build. That makes
+this information harder to find and, for example, makes Sphinx unable to
+generate links to that documentation. Adding ``kernel-doc`` directives to
+the documentation to bring those comments in can help the community derive
+the full value of the work that has gone into creating them.
+
+The ``scripts/find-unused-docs.sh`` tool can be used to find these
+overlooked comments.
+
+Note that the most value comes from pulling in the documentation for
+exported functions and data structures. Many subsystems also have
+kerneldoc comments for internal use; those should not be pulled into the
+documentation build unless they are placed in a document that is
+specifically aimed at developers working within the relevant subsystem.
+
+
+Typo fixes
+~~~~~~~~~~
+
+Fixing typographical or formatting errors in the documentation is a quick
+way to figure out how to create and send patches, and it is a useful
+service. I am always willing to accept such patches. That said, once you
+have fixed a few, please consider moving on to more advanced tasks, leaving
+some typos for the next beginner to address.
+
+Please note that some things are *not* typos and should not be "fixed":
+
+ - Both American and British English spellings are allowed within the
+ kernel documentation. There is no need to fix one by replacing it with
+ the other.
+
+ - The question of whether a period should be followed by one or two spaces
+ is not to be debated in the context of kernel documentation. Other
+ areas of rational disagreement, such as the "Oxford comma", are also
+ off-topic here.
+
+As with any patch to any project, please consider whether your change is
+really making things better.
+
+Ancient documentation
+~~~~~~~~~~~~~~~~~~~~~
+
+Some kernel documentation is current, maintained, and useful. Some
+documentation is ... not. Dusty, old, and inaccurate documentation can
+mislead readers and casts doubt on our documentation as a whole. Anything
+that can be done to address such problems is more than welcome.
+
+Whenever you are working with a document, please consider whether it is
+current, whether it needs updating, or whether it should perhaps be removed
+altogether. There are a number of warning signs that you can pay attention
+to here:
+
+ - References to 2.x kernels
+ - Pointers to SourceForge repositories
+ - Nothing but typo fixes in the history for several years
+ - Discussion of pre-Git workflows
+
+The best thing to do, of course, would be to bring the documentation
+current, adding whatever information is needed. Such work often requires
+the cooperation of developers familiar with the subsystem in question, of
+course. Developers are often more than willing to cooperate with people
+working to improve the documentation when asked nicely, and when their
+answers are listened to and acted upon.
+
+Some documentation is beyond hope; we occasionally find documents that
+refer to code that was removed from the kernel long ago, for example.
+There is surprising resistance to removing obsolete documentation, but we
+should do that anyway. Extra cruft in our documentation helps nobody.
+
+In cases where there is perhaps some useful information in a badly outdated
+document, and you are unable to update it, the best thing to do may be to
+add a warning at the beginning. The following text is recommended::
+
+ .. warning ::
+ This document is outdated and in need of attention. Please use
+ this information with caution, and please consider sending patches
+ to update it.
+
+That way, at least our long-suffering readers have been warned that the
+document may lead them astray.
+
+Documentation coherency
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The old-timers around here will remember the Linux books that showed up on
+the shelves in the 1990s. They were simply collections of documentation
+files scrounged from various locations on the net. The books have (mostly)
+improved since then, but the kernel's documentation is still mostly built
+on that model. It is thousands of files, almost each of which was written
+in isolation from all of the others. We don't have a coherent body of
+kernel documentation; we have thousands of individual documents.
+
+We have been trying to improve the situation through the creation of
+a set of "books" that group documentation for specific readers. These
+include:
+
+ - :doc:`../admin-guide/index`
+ - :doc:`../core-api/index`
+ - :doc:`../driver-api/index`
+ - :doc:`../userspace-api/index`
+
+As well as this book on documentation itself.
+
+Moving documents into the appropriate books is an important task and needs
+to continue. There are a couple of challenges associated with this work,
+though. Moving documentation files creates short-term pain for the people
+who work with those files; they are understandably unenthusiastic about
+such changes. Usually the case can be made to move a document once; we
+really don't want to keep shifting them around, though.
+
+Even when all documents are in the right place, though, we have only
+managed to turn a big pile into a group of smaller piles. The work of
+trying to knit all of those documents together into a single whole has not
+yet begun. If you have bright ideas on how we could proceed on that front,
+we would be more than happy to hear them.
+
+Stylesheet improvements
+~~~~~~~~~~~~~~~~~~~~~~~
+
+With the adoption of Sphinx we have much nicer-looking HTML output than we
+once did. But it could still use a lot of improvement; Donald Knuth and
+Edward Tufte would be unimpressed. That requires tweaking our stylesheets
+to create more typographically sound, accessible, and readable output.
+
+Be warned: if you take on this task you are heading into classic bikeshed
+territory. Expect a lot of opinions and discussion for even relatively
+obvious changes. That is, alas, the nature of the world we live in.
+
+Non-LaTeX PDF build
+~~~~~~~~~~~~~~~~~~~
+
+This is a decidedly nontrivial task for somebody with a lot of time and
+Python skills. The Sphinx toolchain is relatively small and well
+contained; it is easy to add to a development system. But building PDF or
+EPUB output requires installing LaTeX, which is anything but small or well
+contained. That would be a nice thing to eliminate.
+
+The original hope had been to use the rst2pdf tool (https://rst2pdf.org/)
+for PDF generation, but it turned out to not be up to the task.
+Development work on rst2pdf seems to have picked up again in recent times,
+though, which is a hopeful sign. If a suitably motivated developer were to
+work with that project to make rst2pdf work with the kernel documentation
+build, the world would be eternally grateful.
+
+Write more documentation
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Naturally, there are massive parts of the kernel that are severely
+underdocumented. If you have the knowledge to document a specific kernel
+subsystem and the desire to do so, please do not hesitate to do some
+writing and contribute the result to the kernel. Untold numbers of kernel
+developers and users will thank you.

+================================================

+The documentation "subsystem" is the central coordinating point for the

+hierarchy under Documentation/ (with the exception of
+Documentation/device-tree), various utilities under scripts/ and, at least
+some of the time, LICENSES/.
+
+It's worth noting, though, that the boundaries of this subsystem are rather
+fuzzier than normal. Many other subsystem maintainers like to keep control
+of portions of Documentation/, and many more freely apply changes there
+when it is convenient. Beyond that, much of the kernel's documentation is
+found in the source as kerneldoc comments; those are usually (but not
+always) maintained by the relevant subsystem maintainer.
+
+The mailing list for documentation is linux-doc@vger.kernel.org. Patches
+should be made against the docs-next tree whenever possible.
+
+Submit checklist addendum
+-------------------------
+
+When making documentation changes, you should actually build the
+documentation and ensure that no new errors or warnings have been
+introduced. Generating HTML documents and looking at the result will help
+to avoid unsightly misunderstandings about how things will be rendered.
+
+Key cycle dates
+---------------
+
+Patches can be sent anytime, but response will be slower than usual during
+the merge window. The docs tree tends to close late before the merge
+window opens, since the risk of regressions from documentation patches is
+low.
+
+Review cadence
+--------------
+
+I am the sole maintainer for the documentation subsystem, and I am doing
+the work on my own time, so the response to patches will occasionally be
+slow. I try to always send out a notification when a patch is merged (or
+when I decide that one cannot be). Do not hesitate to send a ping if you
+have not heard back within a week of sending a patch.

+=========================
+Using GPIO Lines in Linux
+=========================
+
+The Linux kernel exists to abstract and present hardware to users. GPIO lines
+as such are normally not user facing abstractions. The most obvious, natural
+and preferred way to use GPIO lines is to let kernel hardware drivers deal
+with them.
+
+For examples of already existing generic drivers that will also be good
+examples for any other kernel drivers you want to author, refer to
+:doc:`drivers-on-gpio`
+
+For any kind of mass produced system you want to support, such as servers,
+laptops, phones, tablets, routers, and any consumer or office or business goods
+using appropriate kernel drivers is paramount. Submit your code for inclusion
+in the upstream Linux kernel when you feel it is mature enough and you will get
+help to refine it, see :doc:`../../process/submitting-patches`.
+
+In Linux GPIO lines also have a userspace ABI.
+
+The userspace ABI is intended for one-off deployments. Examples are prototypes,
+factory lines, maker community projects, workshop specimen, production tools,
+industrial automation, PLC-type use cases, door controllers, in short a piece
+of specialized equipment that is not produced by the numbers, requiring
+operators to have a deep knowledge of the equipment and knows about the
+software-hardware interface to be set up. They should not have a natural fit
+to any existing kernel subsystem and not be a good fit for an operating system,
+because of not being reusable or abstract enough, or involving a lot of non
+computer hardware related policy.
+
+Applications that have a good reason to use the industrial I/O (IIO) subsystem
+from userspace will likely be a good fit for using GPIO lines from userspace as
+well.
+
+Do not under any circumstances abuse the GPIO userspace ABI to cut corners in
+any product development projects. If you use it for prototyping, then do not
+productify the prototype: rewrite it using proper kernel drivers. Do not under
+any circumstances deploy any uniform products using GPIO from userspace.
+
+The userspace ABI is a character device for each GPIO hardware unit (GPIO chip).
+These devices will appear on the system as ``/dev/gpiochip0`` thru
+``/dev/gpiochipN``. Examples of how to directly use the userspace ABI can be
+found in the kernel tree ``tools/gpio`` subdirectory.
+
+For structured and managed applications, we recommend that you make use of the
+libgpiod_ library. This provides helper abstractions, command line utlities
+and arbitration for multiple simultaneous consumers on the same GPIO chip.

+Filesystems supported by ADFS
+-----------------------------
+
+The ADFS module supports the following Filecore formats which have:
+
+- new maps
+- new directories or big directories
+
+In terms of the named formats, this means we support:
+
+- E and E+, with or without boot block
+- F and F+
+
+We fully support reading files from these filesystems, and writing to
+existing files within their existing allocation. Essentially, we do
+not support changing any of the filesystem metadata.
+
+This is intended to support loopback mounted Linux native filesystems
+on a RISC OS Filecore filesystem, but will allow the data within files
+to be changed.
+
+If write support (ADFS_FS_RW) is configured, we allow rudimentary
+directory updates, specifically updating the access mode and timestamp.

+(fusermount).
+
+One of the most important features of FUSE is allowing secure,
+non-privileged mounts. This opens up new possibilities for the use of
+filesystems. A good example is sshfs: a secure network filesystem
+using the sftp protocol.
+
+The userspace library and utilities are available from the
+`FUSE homepage: <http://fuse.sourceforge.net/>`_
+
+Filesystem type
+===============
+
+The filesystem type given to mount(2) can be one of the following:
+
+ fuse
+ This is the usual way to mount a FUSE filesystem. The first
+ argument of the mount system call may contain an arbitrary string,
+ which is not interpreted by the kernel.
+
+ fuseblk
+ The filesystem is block device based. The first argument of the
+ mount system call is interpreted as the name of the device.
+
+Mount options
+=============
+
+fd=N
+ The file descriptor to use for communication between the userspace
+ filesystem and the kernel. The file descriptor must have been
+ obtained by opening the FUSE device ('/dev/fuse').
+
+rootmode=M
+ The file mode of the filesystem's root in octal representation.
+
+user_id=N
+ The numeric user id of the mount owner.
+
+group_id=N
+ The numeric group id of the mount owner.
+
+default_permissions
+ By default FUSE doesn't check file access permissions, the
+ filesystem is free to implement its access policy or leave it to
+ the underlying file access mechanism (e.g. in case of network
+ filesystems). This option enables permission checking, restricting
+ access based on file mode. It is usually useful together with the
+ 'allow_other' mount option.
+
+allow_other
+ This option overrides the security measure restricting file access
+ to the user mounting the filesystem. This option is by default only
+ allowed to root, but this restriction can be removed with a
+ (userspace) configuration option.
+
+max_read=N
+ With this option the maximum size of read operations can be set.
+ The default is infinite. Note that the size of read requests is
+ limited anyway to 32 pages (which is 128kbyte on i386).
+
+blksize=N
+ Set the block size for the filesystem. The default is 512. This
+ option is only valid for 'fuseblk' type mounts.
+
+Control filesystem
+==================
+
+There's a control filesystem for FUSE, which can be mounted by::
+
+ mount -t fusectl none /sys/fs/fuse/connections
+
+Mounting it under the '/sys/fs/fuse/connections' directory makes it
+backwards compatible with earlier versions.
+
+Under the fuse control filesystem each connection has a directory
+named by a unique number.
+
+For each connection the following files exist within this directory:
+
+ waiting
+ The number of requests which are waiting to be transferred to
+ userspace or being processed by the filesystem daemon. If there is
+ no filesystem activity and 'waiting' is non-zero, then the
+ filesystem is hung or deadlocked.
+
+ abort
+ Writing anything into this file will abort the filesystem
+ connection. This means that all waiting requests will be aborted an
+ error returned for all aborted and new requests.
+
+Only the owner of the mount may read or write these files.
+
+Interrupting filesystem operations
+##################################
+
+If a process issuing a FUSE filesystem request is interrupted, the
+following will happen:
+
+ - If the request is not yet sent to userspace AND the signal is
+ fatal (SIGKILL or unhandled fatal signal), then the request is
+ dequeued and returns immediately.
+
+ - If the request is not yet sent to userspace AND the signal is not
+ fatal, then an interrupted flag is set for the request. When
+ the request has been successfully transferred to userspace and
+ this flag is set, an INTERRUPT request is queued.
+
+ - If the request is already sent to userspace, then an INTERRUPT
+ request is queued.
+
+INTERRUPT requests take precedence over other requests, so the
+userspace filesystem will receive queued INTERRUPTs before any others.
+
+The userspace filesystem may ignore the INTERRUPT requests entirely,
+or may honor them by sending a reply to the *original* request, with
+the error set to EINTR.
+
+It is also possible that there's a race between processing the
+original request and its INTERRUPT request. There are two possibilities:
+
+ 1. The INTERRUPT request is processed before the original request is
+ processed
+
+ 2. The INTERRUPT request is processed after the original request has
+ been answered
+
+If the filesystem cannot find the original request, it should wait for
+some timeout and/or a number of new requests to arrive, after which it
+should reply to the INTERRUPT request with an EAGAIN error. In case
+1) the INTERRUPT request will be requeued. In case 2) the INTERRUPT
+reply will be ignored.
+
+Aborting a filesystem connection
+================================
+
+It is possible to get into certain situations where the filesystem is
+not responding. Reasons for this may be:
+
+ a) Broken userspace filesystem implementation
+
+ b) Network connection down
+
+ c) Accidental deadlock
+
+ d) Malicious deadlock
+
+(For more on c) and d) see later sections)
+
+In either of these cases it may be useful to abort the connection to
+the filesystem. There are several ways to do this:
+
+ - Kill the filesystem daemon. Works in case of a) and b)
+
+ - Kill the filesystem daemon and all users of the filesystem. Works
+ in all cases except some malicious deadlocks
+
+ - Use forced umount (umount -f). Works in all cases but only if
+ filesystem is still attached (it hasn't been lazy unmounted)
+
+ - Abort filesystem through the FUSE control filesystem. Most
+ powerful method, always works.
+
+How do non-privileged mounts work?
+==================================
+
+Since the mount() system call is a privileged operation, a helper
+program (fusermount) is needed, which is installed setuid root.
+
+The implication of providing non-privileged mounts is that the mount
+owner must not be able to use this capability to compromise the
+system. Obvious requirements arising from this are:
+
+ A) mount owner should not be able to get elevated privileges with the
+ help of the mounted filesystem
+
+ B) mount owner should not get illegitimate access to information from
+ other users' and the super user's processes
+
+ C) mount owner should not be able to induce undesired behavior in
+ other users' or the super user's processes
+
+How are requirements fulfilled?
+===============================
+
+ A) The mount owner could gain elevated privileges by either:
+
+ 1. creating a filesystem containing a device file, then opening this device
+
+ 2. creating a filesystem containing a suid or sgid application, then executing this application
+
+ The solution is not to allow opening device files and ignore
+ setuid and setgid bits when executing programs. To ensure this
+ fusermount always adds "nosuid" and "nodev" to the mount options
+ for non-privileged mounts.
+
+ B) If another user is accessing files or directories in the
+ filesystem, the filesystem daemon serving requests can record the
+ exact sequence and timing of operations performed. This
+ information is otherwise inaccessible to the mount owner, so this
+ counts as an information leak.
+
+ The solution to this problem will be presented in point 2) of C).
+
+ C) There are several ways in which the mount owner can induce
+ undesired behavior in other users' processes, such as:
+
+ 1) mounting a filesystem over a file or directory which the mount
+ owner could otherwise not be able to modify (or could only
+ make limited modifications).
+
+ This is solved in fusermount, by checking the access
+ permissions on the mountpoint and only allowing the mount if
+ the mount owner can do unlimited modification (has write
+ access to the mountpoint, and mountpoint is not a "sticky"
+ directory)
+
+ 2) Even if 1) is solved the mount owner can change the behavior
+ of other users' processes.
+
+ i) It can slow down or indefinitely delay the execution of a
+ filesystem operation creating a DoS against the user or the
+ whole system. For example a suid application locking a
+ system file, and then accessing a file on the mount owner's
+ filesystem could be stopped, and thus causing the system
+ file to be locked forever.
+
+ ii) It can present files or directories of unlimited length, or
+ directory structures of unlimited depth, possibly causing a
+ system process to eat up diskspace, memory or other
+ resources, again causing *DoS*.
+
+ The solution to this as well as B) is not to allow processes
+ to access the filesystem, which could otherwise not be
+ monitored or manipulated by the mount owner. Since if the
+ mount owner can ptrace a process, it can do all of the above
+ without using a FUSE mount, the same criteria as used in
+ ptrace can be used to check if a process is allowed to access
+ the filesystem or not.
+
+ Note that the *ptrace* check is not strictly necessary to
+ prevent B/2/i, it is enough to check if mount owner has enough
+ privilege to send signal to the process accessing the
+ filesystem, since *SIGSTOP* can be used to get a similar effect.
+
+I think these limitations are unacceptable?
+===========================================
+
+If a sysadmin trusts the users enough, or can ensure through other
+measures, that system processes will never enter non-privileged
+mounts, it can relax the last limitation with a 'user_allow_other'
+config option. If this config option is set, the mounting user can
+add the 'allow_other' mount option which disables the check for other
+users' processes.
+
+Kernel - userspace interface
+============================
+
+The following diagram shows how a filesystem operation (in this
+example unlink) is performed in FUSE. ::
+
+
+ | "rm /mnt/fuse/file" | FUSE filesystem daemon
+ | |
+ | | >sys_read()
+ | | >fuse_dev_read()
+ | | >request_wait()
+ | | [sleep on fc->waitq]

+ | <request_wait_answer() |
+ | <request_send() |
+ | [add request to |
+ | fc->unused_list] |
+ | <fuse_unlink() |
+ | <sys_unlink() |
+
+.. note:: Everything in the description above is greatly simplified
+
+There are a couple of ways in which to deadlock a FUSE filesystem.
+Since we are talking about unprivileged userspace programs,
+something must be done about these.
+
+**Scenario 1 - Simple deadlock**::
+
+ | "rm /mnt/fuse/file" | FUSE filesystem daemon
+ | |
+ | >sys_unlink("/mnt/fuse/file") |
+ | [acquire inode semaphore |
+ | for "file"] |
+ | >fuse_unlink() |
+ | [sleep on req->waitq] |
+ | | <sys_read()
+ | | >sys_unlink("/mnt/fuse/file")
+ | | [acquire inode semaphore
+ | | for "file"]
+ | | *DEADLOCK*
+
+The solution for this is to allow the filesystem to be aborted.
+
+**Scenario 2 - Tricky deadlock**
+
+
+This one needs a carefully crafted filesystem. It's a variation on
+the above, only the call back to the filesystem is not explicit,
+but is caused by a pagefault. ::
+
+ | Kamikaze filesystem thread 1 | Kamikaze filesystem thread 2
+ | |
+ | [fd = open("/mnt/fuse/file")] | [request served normally]
+ | [mmap fd to 'addr'] |
+ | [close fd] | [FLUSH triggers 'magic' flag]
+ | [read a byte from addr] |
+ | >do_page_fault() |
+ | [find or create page] |
+ | [lock page] |
+ | >fuse_readpage() |
+ | [queue READ request] |
+ | [sleep on req->waitq] |
+ | | [read request to buffer]
+ | | [create reply header before addr]
+ | | >sys_write(addr - headerlength)
+ | | >fuse_dev_write()
+ | | [look up req in fc->processing]
+ | | [remove from fc->processing]
+ | | [copy write buffer to req]
+ | | >do_page_fault()
+ | | [find or create page]
+ | | [lock page]
+ | | * DEADLOCK *
+
+The solution is basically the same as above.
+
+An additional problem is that while the write buffer is being copied
+to the request, the request must not be interrupted/aborted. This is
+because the destination address of the copy may not be valid after the
+request has returned.
+
+This is solved with doing the copy atomically, and allowing abort
+while the page(s) belonging to the write buffer are faulted with
+get_user_pages(). The 'req->locked' flag indicates when the copy is
+taking place, and abort is delayed until this flag is unset.

-taking place, and abort is delayed until this flag is unset.

-Fault Injection
-===============
-Fault injection is a method for forcing errors that may not normally occur, or
-may be difficult to reproduce. Forcing these errors in a controlled environment
-can help the developer find and fix bugs before their code is shipped in a
-production system. Injecting an error on the Linux NFS server will allow us to
-observe how the client reacts and if it manages to recover its state correctly.
-
-NFSD_FAULT_INJECTION must be selected when configuring the kernel to use this
-feature.
-
-
-Using Fault Injection
-=====================
-On the client, mount the fault injection server through NFS v4.0+ and do some
-work over NFS (open files, take locks, ...).
-
-On the server, mount the debugfs filesystem to <debug_dir> and ls
-<debug_dir>/nfsd. This will show a list of files that will be used for
-injecting faults on the NFS server. As root, write a number n to the file
-corresponding to the action you want the server to take. The server will then
-process the first n items it finds. So if you want to forget 5 locks, echo '5'
-to <debug_dir>/nfsd/forget_locks. A value of 0 will tell the server to forget
-all corresponding items. A log message will be created containing the number
-of items forgotten (check dmesg).
-
-Go back to work on the client and check if the client recovered from the error
-correctly.
-
-
-Available Faults
-================
-forget_clients:
- The NFS server keeps a list of clients that have placed a mount call. If
- this list is cleared, the server will have no knowledge of who the client
- is, forcing the client to reauthenticate with the server.
-
-forget_openowners:
- The NFS server keeps a list of what files are currently opened and who
- they were opened by. Clearing this list will force the client to reopen
- its files.
-
-forget_locks:
- The NFS server keeps a list of what files are currently locked in the VFS.
- Clearing this list will force the client to reclaim its locks (files are
- unlocked through the VFS as they are cleared from this list).
-
-forget_delegations:
- A delegation is used to assure the client that a file, or part of a file,
- has not changed since the delegation was awarded. Clearing this list will
- force the client to reacquire its delegation before accessing the file
- again.
-
-recall_delegations:
- Delegations can be recalled by the server when another client attempts to
- access a file. This test will notify the client that its delegation has
- been revoked, forcing the client to reacquire the delegation before using
- the file again.
-
-
-tools/nfs/inject_faults.sh script
-=================================
-This script has been created to ease the fault injection process. This script
-will detect the mounted debugfs directory and write to the files located there
-based on the arguments passed by the user. For example, running
-`inject_faults.sh forget_locks 1` as root will instruct the server to forget
-one lock. Running `inject_faults forget_locks` will instruct the server to
-forgetall locks.

-
-=========
-ID Mapper
-=========
-Id mapper is used by NFS to translate user and group ids into names, and to
-translate user and group names into ids. Part of this translation involves
-performing an upcall to userspace to request the information. There are two
-ways NFS could obtain this information: placing a call to /sbin/request-key
-or by placing a call to the rpc.idmap daemon.
-
-NFS will attempt to call /sbin/request-key first. If this succeeds, the
-result will be cached using the generic request-key cache. This call should
-only fail if /etc/request-key.conf is not configured for the id_resolver key
-type, see the "Configuring" section below if you wish to use the request-key
-method.
-
-If the call to /sbin/request-key fails (if /etc/request-key.conf is not
-configured with the id_resolver key type), then the idmapper will ask the
-legacy rpc.idmap daemon for the id mapping. This result will be stored
-in a custom NFS idmap cache.
-
-
-===========
-Configuring
-===========
-The file /etc/request-key.conf will need to be modified so /sbin/request-key can
-direct the upcall. The following line should be added:
-
-#OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ...
-#====== ======= =============== =============== ===============================
-create id_resolver * * /usr/sbin/nfs.idmap %k %d 600
-
-This will direct all id_resolver requests to the program /usr/sbin/nfs.idmap.
-The last parameter, 600, defines how many seconds into the future the key will
-expire. This parameter is optional for /usr/sbin/nfs.idmap. When the timeout
-is not specified, nfs.idmap will default to 600 seconds.
-
-id mapper uses for key descriptions:
- uid: Find the UID for the given user
- gid: Find the GID for the given group
- user: Find the user name for the given UID
- group: Find the group name for the given GID
-
-You can handle any of these individually, rather than using the generic upcall
-program. If you would like to use your own program for a uid lookup then you
-would edit your request-key.conf so it look similar to this:
-
-#OP TYPE DESCRIPTION CALLOUT INFO PROGRAM ARG1 ARG2 ARG3 ...
-#====== ======= =============== =============== ===============================
-create id_resolver uid:* * /some/other/program %k %d 600
-create id_resolver * * /usr/sbin/nfs.idmap %k %d 600
-
-Notice that the new line was added above the line for the generic program.
-request-key will find the first matching line and corresponding program. In
-this case, /some/other/program will handle all uid lookups and
-/usr/sbin/nfs.idmap will handle gid, user, and group lookups.
-
-See <file:Documentation/security/keys/request-key.rst> for more information
-about the request-key function.
-
-
-=========
-nfs.idmap
-=========
-nfs.idmap is designed to be called by request-key, and should not be run "by
-hand". This program takes two arguments, a serialized key and a key
-description. The serialized key is first converted into a key_serial_t, and
-then passed as an argument to keyctl_instantiate (both are part of keyutils.h).
-
-The actual lookups are performed by functions found in nfsidmap.h. nfs.idmap
-determines the correct function to call by looking at the first part of the
-description string. For example, a uid lookup description will appear as
-"uid:user@domain".
-
-nfs.idmap will return 0 if the key was instantiated, and non-zero otherwise.

-
-Overview
-~~~~~~~~
-
- This document describes how to install and setup the Linux NFS/RDMA client
- and server software.
-
- The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server
- was first included in the following release, Linux 2.6.25.
-
- In our testing, we have obtained excellent performance results (full 10Gbit
- wire bandwidth at minimal client CPU) under many workloads. The code passes
- the full Connectathon test suite and operates over both Infiniband and iWARP
- RDMA adapters.
-
-Getting Help
-~~~~~~~~~~~~
-
- If you get stuck, you can ask questions on the
-
- nfs-rdma-devel@lists.sourceforge.net
-
- mailing list.
-
-Installation
-~~~~~~~~~~~~
-
- These instructions are a step by step guide to building a machine for
- use with NFS/RDMA.
-
- - Install an RDMA device
-
- Any device supported by the drivers in drivers/infiniband/hw is acceptable.
-
- Testing has been performed using several Mellanox-based IB cards, the
- Ammasso AMS1100 iWARP adapter, and the Chelsio cxgb3 iWARP adapter.
-
- - Install a Linux distribution and tools
-
- The first kernel release to contain both the NFS/RDMA client and server was
- Linux 2.6.25 Therefore, a distribution compatible with this and subsequent
- Linux kernel release should be installed.
-
- The procedures described in this document have been tested with
- distributions from Red Hat's Fedora Project (http://fedora.redhat.com/).
-
- - Install nfs-utils-1.1.2 or greater on the client
-
- An NFS/RDMA mount point can be obtained by using the mount.nfs command in
- nfs-utils-1.1.2 or greater (nfs-utils-1.1.1 was the first nfs-utils
- version with support for NFS/RDMA mounts, but for various reasons we
- recommend using nfs-utils-1.1.2 or greater). To see which version of
- mount.nfs you are using, type:
-
- $ /sbin/mount.nfs -V
-
- If the version is less than 1.1.2 or the command does not exist,
- you should install the latest version of nfs-utils.
-
- Download the latest package from:
-
- http://www.kernel.org/pub/linux/utils/nfs
-
- Uncompress the package and follow the installation instructions.
-
- If you will not need the idmapper and gssd executables (you do not need
- these to create an NFS/RDMA enabled mount command), the installation
- process can be simplified by disabling these features when running
- configure:
-
- $ ./configure --disable-gss --disable-nfsv4
-
- To build nfs-utils you will need the tcp_wrappers package installed. For
- more information on this see the package's README and INSTALL files.
-
- After building the nfs-utils package, there will be a mount.nfs binary in
- the utils/mount directory. This binary can be used to initiate NFS v2, v3,
- or v4 mounts. To initiate a v4 mount, the binary must be called
- mount.nfs4. The standard technique is to create a symlink called
- mount.nfs4 to mount.nfs.
-
- This mount.nfs binary should be installed at /sbin/mount.nfs as follows:
-
- $ sudo cp utils/mount/mount.nfs /sbin/mount.nfs
-
- In this location, mount.nfs will be invoked automatically for NFS mounts
- by the system mount command.
-
- NOTE: mount.nfs and therefore nfs-utils-1.1.2 or greater is only needed
- on the NFS client machine. You do not need this specific version of
- nfs-utils on the server. Furthermore, only the mount.nfs command from
- nfs-utils-1.1.2 is needed on the client.
-
- - Install a Linux kernel with NFS/RDMA
-
- The NFS/RDMA client and server are both included in the mainline Linux
- kernel version 2.6.25 and later. This and other versions of the Linux
- kernel can be found at:
-
- https://www.kernel.org/pub/linux/kernel/
-
- Download the sources and place them in an appropriate location.
-
- - Configure the RDMA stack
-
- Make sure your kernel configuration has RDMA support enabled. Under
- Device Drivers -> InfiniBand support, update the kernel configuration
- to enable InfiniBand support [NOTE: the option name is misleading. Enabling
- InfiniBand support is required for all RDMA devices (IB, iWARP, etc.)].
-
- Enable the appropriate IB HCA support (mlx4, mthca, ehca, ipath, etc.) or
- iWARP adapter support (amso, cxgb3, etc.).
-
- If you are using InfiniBand, be sure to enable IP-over-InfiniBand support.
-
- - Configure the NFS client and server
-
- Your kernel configuration must also have NFS file system support and/or
- NFS server support enabled. These and other NFS related configuration
- options can be found under File Systems -> Network File Systems.
-
- - Build, install, reboot
-
- The NFS/RDMA code will be enabled automatically if NFS and RDMA
- are turned on. The NFS/RDMA client and server are configured via the hidden
- SUNRPC_XPRT_RDMA config option that depends on SUNRPC and INFINIBAND. The
- value of SUNRPC_XPRT_RDMA will be:
-
- - N if either SUNRPC or INFINIBAND are N, in this case the NFS/RDMA client
- and server will not be built
- - M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M,
- in this case the NFS/RDMA client and server will be built as modules
- - Y if both SUNRPC and INFINIBAND are Y, in this case the NFS/RDMA client
- and server will be built into the kernel
-
- Therefore, if you have followed the steps above and turned no NFS and RDMA,
- the NFS/RDMA client and server will be built.
-
- Build a new kernel, install it, boot it.
-
-Check RDMA and NFS Setup
-~~~~~~~~~~~~~~~~~~~~~~~~
-
- Before configuring the NFS/RDMA software, it is a good idea to test
- your new kernel to ensure that the kernel is working correctly.
- In particular, it is a good idea to verify that the RDMA stack
- is functioning as expected and standard NFS over TCP/IP and/or UDP/IP
- is working properly.
-
- - Check RDMA Setup
-
- If you built the RDMA components as modules, load them at
- this time. For example, if you are using a Mellanox Tavor/Sinai/Arbel
- card:
-
- $ modprobe ib_mthca
- $ modprobe ib_ipoib
-
- If you are using InfiniBand, make sure there is a Subnet Manager (SM)
- running on the network. If your IB switch has an embedded SM, you can
- use it. Otherwise, you will need to run an SM, such as OpenSM, on one
- of your end nodes.
-
- If an SM is running on your network, you should see the following:
-
- $ cat /sys/class/infiniband/driverX/ports/1/state
- 4: ACTIVE
-
- where driverX is mthca0, ipath5, ehca3, etc.
-
- To further test the InfiniBand software stack, use IPoIB (this
- assumes you have two IB hosts named host1 and host2):
-
- host1$ ip link set dev ib0 up
- host1$ ip address add dev ib0 a.b.c.x
- host2$ ip link set dev ib0 up
- host2$ ip address add dev ib0 a.b.c.y
- host1$ ping a.b.c.y
- host2$ ping a.b.c.x
-
- For other device types, follow the appropriate procedures.
-
- - Check NFS Setup
-
- For the NFS components enabled above (client and/or server),
- test their functionality over standard Ethernet using TCP/IP or UDP/IP.
-
-NFS/RDMA Setup
-~~~~~~~~~~~~~~
-
- We recommend that you use two machines, one to act as the client and
- one to act as the server.
-
- One time configuration:
-
- - On the server system, configure the /etc/exports file and
- start the NFS/RDMA server.
-
- Exports entries with the following formats have been tested:
-
- /vol0 192.168.0.47(fsid=0,rw,async,insecure,no_root_squash)
- /vol0 192.168.0.0/255.255.255.0(fsid=0,rw,async,insecure,no_root_squash)
-
- The IP address(es) is(are) the client's IPoIB address for an InfiniBand
- HCA or the client's iWARP address(es) for an RNIC.
-
- NOTE: The "insecure" option must be used because the NFS/RDMA client does
- not use a reserved port.
-
- Each time a machine boots:
-
- - Load and configure the RDMA drivers
-
- For InfiniBand using a Mellanox adapter:
-
- $ modprobe ib_mthca
- $ modprobe ib_ipoib
- $ ip li set dev ib0 up
- $ ip addr add dev ib0 a.b.c.d
-
- NOTE: use unique addresses for the client and server
-
- - Start the NFS server
-
- If the NFS/RDMA server was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
- kernel config), load the RDMA transport module:
-
- $ modprobe svcrdma
-
- Regardless of how the server was built (module or built-in), start the
- server:
-
- $ /etc/init.d/nfs start
-
- or
-
- $ service nfs start
-
- Instruct the server to listen on the RDMA transport:
-
- $ echo rdma 20049 > /proc/fs/nfsd/portlist
-
- - On the client system
-
- If the NFS/RDMA client was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
- kernel config), load the RDMA client module:
-
- $ modprobe xprtrdma.ko
-
- Regardless of how the client was built (module or built-in), use this
- command to mount the NFS/RDMA server:
-
- $ mount -o rdma,port=20049 <IPoIB-server-name-or-address>:/<export> /mnt
-
- To verify that the mount is using RDMA, run "cat /proc/mounts" and check
- the "proto" field for the given mount.
-
- Congratulations! You're using NFS/RDMA!

-The NFS client
-==============
-
-The NFS version 2 protocol was first documented in RFC1094 (March 1989).
-Since then two more major releases of NFS have been published, with NFSv3
-being documented in RFC1813 (June 1995), and NFSv4 in RFC3530 (April
-2003).
-
-The Linux NFS client currently supports all the above published versions,
-and work is in progress on adding support for minor version 1 of the NFSv4
-protocol.
-
-The purpose of this document is to provide information on some of the
-special features of the NFS client that can be configured by system
-administrators.
-
-
-The nfs4_unique_id parameter
-============================
-
-NFSv4 requires clients to identify themselves to servers with a unique
-string. File open and lock state shared between one client and one server
-is associated with this identity. To support robust NFSv4 state recovery
-and transparent state migration, this identity string must not change
-across client reboots.
-
-Without any other intervention, the Linux client uses a string that contains
-the local system's node name. System administrators, however, often do not
-take care to ensure that node names are fully qualified and do not change
-over the lifetime of a client system. Node names can have other
-administrative requirements that require particular behavior that does not
-work well as part of an nfs_client_id4 string.
-
-The nfs.nfs4_unique_id boot parameter specifies a unique string that can be
-used instead of a system's node name when an NFS client identifies itself to
-a server. Thus, if the system's node name is not unique, or it changes, its
-nfs.nfs4_unique_id stays the same, preventing collision with other clients
-or loss of state during NFS reboot recovery or transparent state migration.
-
-The nfs.nfs4_unique_id string is typically a UUID, though it can contain
-anything that is believed to be unique across all NFS clients. An
-nfs4_unique_id string should be chosen when a client system is installed,
-just as a system's root file system gets a fresh UUID in its label at
-install time.
-
-The string should remain fixed for the lifetime of the client. It can be
-changed safely if care is taken that the client shuts down cleanly and all
-outstanding NFSv4 state has expired, to prevent loss of NFSv4 state.
-
-This string can be stored in an NFS client's grub.conf, or it can be provided
-via a net boot facility such as PXE. It may also be specified as an nfs.ko
-module parameter. Specifying a uniquifier string is not support for NFS
-clients running in containers.
-
-
-The DNS resolver
-================
-
-NFSv4 allows for one server to refer the NFS client to data that has been
-migrated onto another server by means of the special "fs_locations"
-attribute. See
- http://tools.ietf.org/html/rfc3530#section-6
-and
- http://tools.ietf.org/html/draft-ietf-nfsv4-referrals-00
-
-The fs_locations information can take the form of either an ip address and
-a path, or a DNS hostname and a path. The latter requires the NFS client to
-do a DNS lookup in order to mount the new volume, and hence the need for an
-upcall to allow userland to provide this service.
-
-Assuming that the user has the 'rpc_pipefs' filesystem mounted in the usual
-/var/lib/nfs/rpc_pipefs, the upcall consists of the following steps:
-
- (1) The process checks the dns_resolve cache to see if it contains a
- valid entry. If so, it returns that entry and exits.
-
- (2) If no valid entry exists, the helper script '/sbin/nfs_cache_getent'
- (may be changed using the 'nfs.cache_getent' kernel boot parameter)
- is run, with two arguments:
- - the cache name, "dns_resolve"
- - the hostname to resolve
-
- (3) After looking up the corresponding ip address, the helper script
- writes the result into the rpc_pipefs pseudo-file
- '/var/lib/nfs/rpc_pipefs/cache/dns_resolve/channel'
- in the following (text) format:
-
- "<ip address> <hostname> <ttl>\n"
-
- Where <ip address> is in the usual IPv4 (123.456.78.90) or IPv6
- (ffee:ddcc:bbaa:9988:7766:5544:3322:1100, ffee::1100, ...) format.
- <hostname> is identical to the second argument of the helper
- script, and <ttl> is the 'time to live' of this cache entry (in
- units of seconds).
-
- Note: If <ip address> is invalid, say the string "0", then a negative
- entry is created, which will cause the kernel to treat the hostname
- as having no valid DNS translation.
-
-
-
-
-A basic sample /sbin/nfs_cache_getent
-=====================================
-
-#!/bin/bash
-#
-ttl=600
-#
-cut=/usr/bin/cut
-getent=/usr/bin/getent
-rpc_pipefs=/var/lib/nfs/rpc_pipefs
-#
-die()
-{
- echo "Usage: $0 cache_name entry_name"
- exit 1
-}
-
-[ $# -lt 2 ] && die
-cachename="$1"
-cache_path=${rpc_pipefs}/cache/${cachename}/channel
-
-case "${cachename}" in
- dns_resolve)

-Administrative interfaces for nfsd
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Note that normally these interfaces are used only by the utilities in
-nfs-utils.
-
-nfsd is controlled mainly by pseudofiles under the "nfsd" filesystem,
-which is normally mounted at /proc/fs/nfsd/.
-
-The server is always started by the first write of a nonzero value to
-nfsd/threads.
-
-Before doing that, NFSD can be told which sockets to listen on by
-writing to nfsd/portlist; that write may be:
-
- - an ascii-encoded file descriptor, which should refer to a
- bound (and listening, for tcp) socket, or
- - "transportname port", where transportname is currently either
- "udp", "tcp", or "rdma".
-
-If nfsd is started without doing any of these, then it will create one
-udp and one tcp listener at port 2049 (see nfsd_init_socks).
-
-On startup, nfsd and lockd grace periods start.
-
-nfsd is shut down by a write of 0 to nfsd/threads. All locks and state
-are thrown away at that point.
-
-Between startup and shutdown, the number of threads may be adjusted up
-or down by additional writes to nfsd/threads or by writes to
-nfsd/pool_threads.
-
-For more detail about files under nfsd/ and what they control, see
-fs/nfsd/nfsctl.c; most of them have detailed comments.
-
-Implementation notes
-^^^^^^^^^^^^^^^^^^^^

-Mounting the root filesystem via NFS (nfsroot)
-===============================================
-
-Written 1996 by Gero Kuhlmann <gero@gkminix.han.de>
-Updated 1997 by Martin Mares <mj@atrey.karlin.mff.cuni.cz>
-Updated 2006 by Nico Schottelius <nico-kernel-nfsroot@schottelius.org>

-
-
-
-In order to use a diskless system, such as an X-terminal or printer server
-for example, it is necessary for the root filesystem to be present on a
-non-disk device. This may be an initramfs (see Documentation/filesystems/
-ramfs-rootfs-initramfs.txt), a ramdisk (see Documentation/admin-guide/initrd.rst) or a
-filesystem mounted via NFS. The following text describes on how to use NFS
-for the root filesystem. For the rest of this text 'client' means the
-diskless system, and 'server' means the NFS server.
-
-
-
-
-1.) Enabling nfsroot capabilities
- -----------------------------
-
-In order to use nfsroot, NFS client support needs to be selected as
-built-in during configuration. Once this has been selected, the nfsroot
-option will become available, which should also be selected.
-
-In the networking options, kernel level autoconfiguration can be selected,
-along with the types of autoconfiguration to support. Selecting all of
-DHCP, BOOTP and RARP is safe.
-
-
-
-
-2.) Kernel command line
- -------------------
-
-When the kernel has been loaded by a boot loader (see below) it needs to be
-told what root fs device to use. And in the case of nfsroot, where to find
-both the server and the name of the directory on the server to mount as root.
-This can be established using the following kernel command line parameters:
-
-
-root=/dev/nfs
-
- This is necessary to enable the pseudo-NFS-device. Note that it's not a
- real device but just a synonym to tell the kernel to use NFS instead of
- a real device.
-
-
-nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
-
- If the `nfsroot' parameter is NOT given on the command line,
- the default "/tftpboot/%s" will be used.
-
- <server-ip> Specifies the IP address of the NFS server.
- The default address is determined by the `ip' parameter
- (see below). This parameter allows the use of different
- servers for IP autoconfiguration and NFS.
-
- <root-dir> Name of the directory on the server to mount as root.
- If there is a "%s" token in the string, it will be
- replaced by the ASCII-representation of the client's
- IP address.
-
- <nfs-options> Standard NFS options. All options are separated by commas.
- The following defaults are used:
- port = as given by server portmap daemon
- rsize = 4096
- wsize = 4096
- timeo = 7
- retrans = 3
- acregmin = 3
- acregmax = 60
- acdirmin = 30
- acdirmax = 60
- flags = hard, nointr, noposix, cto, ac
-
-
-ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>:
- <dns0-ip>:<dns1-ip>:<ntp0-ip>
-
- This parameter tells the kernel how to configure IP addresses of devices
- and also how to set up the IP routing table. It was originally called
- `nfsaddrs', but now the boot-time IP configuration works independently of
- NFS, so it was renamed to `ip' and the old name remained as an alias for
- compatibility reasons.
-
- If this parameter is missing from the kernel command line, all fields are
- assumed to be empty, and the defaults mentioned below apply. In general
- this means that the kernel tries to configure everything using
- autoconfiguration.
-
- The <autoconf> parameter can appear alone as the value to the `ip'
- parameter (without all the ':' characters before). If the value is
- "ip=off" or "ip=none", no autoconfiguration will take place, otherwise
- autoconfiguration will take place. The most common way to use this
- is "ip=dhcp".
-
- <client-ip> IP address of the client.
-
- Default: Determined using autoconfiguration.
-
- <server-ip> IP address of the NFS server. If RARP is used to determine
- the client address and this parameter is NOT empty only
- replies from the specified server are accepted.
-
- Only required for NFS root. That is autoconfiguration
- will not be triggered if it is missing and NFS root is not
- in operation.
-
- Value is exported to /proc/net/pnp with the prefix "bootserver "
- (see below).
-
- Default: Determined using autoconfiguration.
- The address of the autoconfiguration server is used.
-
- <gw-ip> IP address of a gateway if the server is on a different subnet.
-
- Default: Determined using autoconfiguration.
-
- <netmask> Netmask for local network interface. If unspecified
- the netmask is derived from the client IP address assuming
- classful addressing.
-
- Default: Determined using autoconfiguration.
-
- <hostname> Name of the client. If a '.' character is present, anything
- before the first '.' is used as the client's hostname, and anything
- after it is used as its NIS domain name. May be supplied by
- autoconfiguration, but its absence will not trigger autoconfiguration.
- If specified and DHCP is used, the user-provided hostname (and NIS
- domain name, if present) will be carried in the DHCP request; this
- may cause a DNS record to be created or updated for the client.
-
- Default: Client IP address is used in ASCII notation.
-
- <device> Name of network device to use.
-
- Default: If the host only has one device, it is used.
- Otherwise the device is determined using
- autoconfiguration. This is done by sending
- autoconfiguration requests out of all devices,
- and using the device that received the first reply.
-
- <autoconf> Method to use for autoconfiguration. In the case of options
- which specify multiple autoconfiguration protocols,
- requests are sent using all protocols, and the first one
- to reply is used.
-
- Only autoconfiguration protocols that have been compiled
- into the kernel will be used, regardless of the value of
- this option.
-
- off or none: don't use autoconfiguration
- (do static IP assignment instead)
- on or any: use any protocol available in the kernel
- (default)
- dhcp: use DHCP
- bootp: use BOOTP
- rarp: use RARP
- both: use both BOOTP and RARP but not DHCP
- (old option kept for backwards compatibility)
-
- if dhcp is used, the client identifier can be used by following
- format "ip=dhcp,client-id-type,client-id-value"
-
- Default: any
-
- <dns0-ip> IP address of primary nameserver.
- Value is exported to /proc/net/pnp with the prefix "nameserver "
- (see below).
-
- Default: None if not using autoconfiguration; determined
- automatically if using autoconfiguration.
-
- <dns1-ip> IP address of secondary nameserver.
- See <dns0-ip>.
-
- <ntp0-ip> IP address of a Network Time Protocol (NTP) server.
- Value is exported to /proc/net/ipconfig/ntp_servers, but is
- otherwise unused (see below).
-
- Default: None if not using autoconfiguration; determined
- automatically if using autoconfiguration.
-
- After configuration (whether manual or automatic) is complete, two files
- are created in the following format; lines are omitted if their respective
- value is empty following configuration:
-
- - /proc/net/pnp:
-
- #PROTO: <DHCP|BOOTP|RARP|MANUAL> (depending on configuration method)
- domain <dns-domain> (if autoconfigured, the DNS domain)
- nameserver <dns0-ip> (primary name server IP)
- nameserver <dns1-ip> (secondary name server IP)
- nameserver <dns2-ip> (tertiary name server IP)
- bootserver <server-ip> (NFS server IP)
-
- - /proc/net/ipconfig/ntp_servers:
-
- <ntp0-ip> (NTP server IP)
- <ntp1-ip> (NTP server IP)
- <ntp2-ip> (NTP server IP)
-
- <dns-domain> and <dns2-ip> (in /proc/net/pnp) and <ntp1-ip> and <ntp2-ip>
- (in /proc/net/ipconfig/ntp_servers) are requested during autoconfiguration;
- they cannot be specified as part of the "ip=" kernel command line parameter.
-
- Because the "domain" and "nameserver" options are recognised by DNS
- resolvers, /etc/resolv.conf is often linked to /proc/net/pnp on systems
- that use an NFS root filesystem.
-
- Note that the kernel will not synchronise the system time with any NTP
- servers it discovers; this is the responsibility of a user space process
- (e.g. an initrd/initramfs script that passes the IP addresses listed in
- /proc/net/ipconfig/ntp_servers to an NTP client before mounting the real
- root filesystem if it is on NFS).
-
-
-nfsrootdebug
-
- This parameter enables debugging messages to appear in the kernel
- log at boot time so that administrators can verify that the correct
- NFS mount options, server address, and root path are passed to the
- NFS client.
-
-
-rdinit=<executable file>
-
- To specify which file contains the program that starts system
- initialization, administrators can use this command line parameter.
- The default value of this parameter is "/init". If the specified
- file exists and the kernel can execute it, root filesystem related
- kernel command line parameters, including `nfsroot=', are ignored.
-
- A description of the process of mounting the root file system can be
- found in:
-
- Documentation/driver-api/early-userspace/early_userspace_support.rst
-
-
-
-
-3.) Boot Loader
- ----------
-
-To get the kernel into memory different approaches can be used.
-They depend on various facilities being available:
-
-
-3.1) Booting from a floppy using syslinux
-
- When building kernels, an easy way to create a boot floppy that uses
- syslinux is to use the zdisk or bzdisk make targets which use zimage
- and bzimage images respectively. Both targets accept the
- FDARGS parameter which can be used to set the kernel command line.
-
- e.g.
- make bzdisk FDARGS="root=/dev/nfs"
-
- Note that the user running this command will need to have
- access to the floppy drive device, /dev/fd0
-
- For more information on syslinux, including how to create bootdisks
- for prebuilt kernels, see http://syslinux.zytor.com/
-
- N.B: Previously it was possible to write a kernel directly to
- a floppy using dd, configure the boot device using rdev, and
- boot using the resulting floppy. Linux no longer supports this
- method of booting.
-
-3.2) Booting from a cdrom using isolinux
-
- When building kernels, an easy way to create a bootable cdrom that
- uses isolinux is to use the isoimage target which uses a bzimage
- image. Like zdisk and bzdisk, this target accepts the FDARGS
- parameter which can be used to set the kernel command line.
-
- e.g.
- make isoimage FDARGS="root=/dev/nfs"
-
- The resulting iso image will be arch/<ARCH>/boot/image.iso
- This can be written to a cdrom using a variety of tools including
- cdrecord.
-
- e.g.
- cdrecord dev=ATAPI:1,0,0 arch/x86/boot/image.iso
-
- For more information on isolinux, including how to create bootdisks
- for prebuilt kernels, see http://syslinux.zytor.com/
-
-3.2) Using LILO
- When using LILO all the necessary command line parameters may be
- specified using the 'append=' directive in the LILO configuration
- file.
-
- However, to use the 'root=' directive you also need to create
- a dummy root device, which may be removed after LILO is run.
-
- mknod /dev/boot255 c 0 255
-
- For information on configuring LILO, please refer to its documentation.
-
-3.3) Using GRUB
- When using GRUB, kernel parameter are simply appended after the kernel
- specification: kernel <kernel> <parameters>
-
-3.4) Using loadlin
- loadlin may be used to boot Linux from a DOS command prompt without
- requiring a local hard disk to mount as root. This has not been
- thoroughly tested by the authors of this document, but in general
- it should be possible configure the kernel command line similarly
- to the configuration of LILO.
-
- Please refer to the loadlin documentation for further information.
-
-3.5) Using a boot ROM
- This is probably the most elegant way of booting a diskless client.
- With a boot ROM the kernel is loaded using the TFTP protocol. The
- authors of this document are not aware of any no commercial boot
- ROMs that support booting Linux over the network. However, there
- are two free implementations of a boot ROM, netboot-nfs and
- etherboot, both of which are available on sunsite.unc.edu, and both
- of which contain everything you need to boot a diskless Linux client.
-
-3.6) Using pxelinux
- Pxelinux may be used to boot linux using the PXE boot loader
- which is present on many modern network cards.
-
- When using pxelinux, the kernel image is specified using
- "kernel <relative-path-below /tftpboot>". The nfsroot parameters
- are passed to the kernel by adding them to the "append" line.
- It is common to use serial console in conjunction with pxeliunx,
- see Documentation/admin-guide/serial-console.rst for more information.
-
- For more information on isolinux, including how to create bootdisks
- for prebuilt kernels, see http://syslinux.zytor.com/

+
+In order to allow userspace to protect itself against certain race conditions

+``LOOKUP_NO_MAGICLINKS`` and other magic-link restrictions are implemented.
+
+``LOOKUP_NO_XDEV`` blocks all ``vfsmount`` traversals (this includes both
+bind-mounts and ordinary mounts). Note that the ``vfsmount`` which contains the
+lookup is determined by the first mountpoint the path lookup reaches --
+absolute paths start with the ``vfsmount`` of ``/``, and relative paths start
+with the ``dfd``'s ``vfsmount``. Magic-links are only permitted if the
+``vfsmount`` of the path is unchanged.
+
+``LOOKUP_BENEATH`` blocks any path components which resolve outside the
+starting point of the resolution. This is done by blocking ``nd_jump_root()``
+as well as blocking ".." if it would jump outside the starting point.
+``rename_lock`` and ``mount_lock`` are used to detect attacks against the
+resolution of "..". Magic-links are also blocked.
+
+``LOOKUP_IN_ROOT`` resolves all path components as though the starting point
+were the filesystem root. ``nd_jump_root()`` brings the resolution back to to
+the starting point, and ".." at the starting point will act as a no-op. As with
+``LOOKUP_BENEATH``, ``rename_lock`` and ``mount_lock`` are used to detect
+attacks against ".." resolution. Magic-links are also blocked.

+
+USING VFAT
+==========
+
+To use the vfat filesystem, use the filesystem type 'vfat'. i.e.::
+
+ mount -t vfat /dev/fd0 /mnt
+
+
+No special partition formatter is required,
+'mkdosfs' will work fine if you want to format from within Linux.
+
+VFAT MOUNT OPTIONS
+==================
+
+**uid=###**
+ Set the owner of all files on this filesystem.
+ The default is the uid of current process.
+
+**gid=###**
+ Set the group of all files on this filesystem.
+ The default is the gid of current process.
+
+**umask=###**
+ The permission mask (for files and directories, see *umask(1)*).
+ The default is the umask of current process.
+
+**dmask=###**
+ The permission mask for the directory.
+ The default is the umask of current process.
+
+**fmask=###**
+ The permission mask for files.
+ The default is the umask of current process.
+
+**allow_utime=###**
+ This option controls the permission check of mtime/atime.
+
+ **-20**: If current process is in group of file's group ID,
+ you can change timestamp.
+
+ **-2**: Other users can change timestamp.
+
+ The default is set from dmask option. If the directory is
+ writable, utime(2) is also allowed. i.e. ~dmask & 022.
+
+ Normally utime(2) checks current process is owner of
+ the file, or it has CAP_FOWNER capability. But FAT
+ filesystem doesn't have uid/gid on disk, so normal
+ check is too unflexible. With this option you can
+ relax it.
+
+**codepage=###**
+ Sets the codepage number for converting to shortname
+ characters on FAT filesystem.
+ By default, FAT_DEFAULT_CODEPAGE setting is used.
+
+**iocharset=<name>**
+ Character set to use for converting between the
+ encoding is used for user visible filename and 16 bit
+ Unicode characters. Long filenames are stored on disk
+ in Unicode format, but Unix for the most part doesn't
+ know how to deal with Unicode.
+ By default, FAT_DEFAULT_IOCHARSET setting is used.
+
+ There is also an option of doing UTF-8 translations
+ with the utf8 option.
+
+.. note:: ``iocharset=utf8`` is not recommended. If unsure, you should consider
+ the utf8 option instead.
+
+**utf8=<bool>**
+ UTF-8 is the filesystem safe version of Unicode that
+ is used by the console. It can be enabled or disabled
+ for the filesystem with this option.
+ If 'uni_xlate' gets set, UTF-8 gets disabled.
+ By default, FAT_DEFAULT_UTF8 setting is used.
+
+**uni_xlate=<bool>**
+ Translate unhandled Unicode characters to special
+ escaped sequences. This would let you backup and
+ restore filenames that are created with any Unicode
+ characters. Until Linux supports Unicode for real,
+ this gives you an alternative. Without this option,
+ a '?' is used when no translation is possible. The
+ escape character is ':' because it is otherwise
+ illegal on the vfat filesystem. The escape sequence
+ that gets used is ':' and the four digits of hexadecimal
+ unicode.
+
+**nonumtail=<bool>**
+ When creating 8.3 aliases, normally the alias will
+ end in '~1' or tilde followed by some number. If this
+ option is set, then if the filename is
+ "longfilename.txt" and "longfile.txt" does not
+ currently exist in the directory, longfile.txt will
+ be the short alias instead of longfi~1.txt.
+
+**usefree**

+**time_offset=minutes**
+ Set offset for conversion of timestamps from local time

+
+ **stale_rw**: This option maintains an index (cache) of directory

+ improve look-ups. Full file operations (read/write) over NFS is
+ supported but with cache eviction at NFS server, this could
+ result in ESTALE issues.
+
+ **nostale_ro**: This option bases the *inode* number and filehandle
+ on the on-disk location of a file in the MS-DOS directory entry.
+ This ensures that ESTALE will not be returned after a file is
+ evicted from the inode cache. However, it means that operations
+ such as rename, create and unlink could cause filehandles that
+ previously pointed at one file to point at a different file,

+
+
+
+LIMITATION
+==========
+
+The fallocated region of file is discarded at umount/evict time
+when using fallocate with FALLOC_FL_KEEP_SIZE.
+So, User should assume that fallocated region can be discarded at
+last close if there is memory pressure resulting in eviction of
+the inode from the memory. As a result, for any dependency on
+the fallocated region, user should make sure to recheck fallocate
+after reopening the file.
+
+TODO
+====
+Need to get rid of the raw scanning stuff. Instead, always use
+a get next directory entry approach. The only thing left that uses
+raw scanning is the directory renaming code.
+
+
+POSSIBLE PROBLEMS
+=================
+
+- vfat_valid_longname does not properly checked reserved names.
+- When a volume name is the same as a directory name in the root
+ directory of the filesystem, the directory name sometimes shows

+
+NOTES ON THE STRUCTURE OF THE VFAT FILESYSTEM
+=============================================
+This documentation was provided by Galen C. Hunt gchunt@cs.rochester.edu and
+lightly annotated by Gordon Chaffee.
+
+This document presents a very rough, technical overview of my
+knowledge of the extended FAT file system used in Windows NT 3.5 and
+Windows 95. I don't guarantee that any of the following is correct,
+but it appears to be so.
+
+The extended FAT file system is almost identical to the FAT
+file system used in DOS versions up to and including *6.223410239847*
+:-). The significant change has been the addition of long file names.
+These names support up to 255 characters including spaces and lower
+case characters as opposed to the traditional 8.3 short names.
+
+Here is the description of the traditional FAT entry in the current
+Windows 95 filesystem::
+
+ struct directory { // Short 8.3 names
+ unsigned char name[8]; // file name
+ unsigned char ext[3]; // file extension
+ unsigned char attr; // attribute byte
+ unsigned char lcase; // Case for base and extension
+ unsigned char ctime_ms; // Creation time, milliseconds
+ unsigned char ctime[2]; // Creation time
+ unsigned char cdate[2]; // Creation date
+ unsigned char adate[2]; // Last access date
+ unsigned char reserved[2]; // reserved values (ignored)
+ unsigned char time[2]; // time stamp
+ unsigned char date[2]; // date stamp
+ unsigned char start[2]; // starting cluster number
+ unsigned char size[4]; // size of the file
+ };
+
+
+The lcase field specifies if the base and/or the extension of an 8.3
+name should be capitalized. This field does not seem to be used by
+Windows 95 but it is used by Windows NT. The case of filenames is not
+completely compatible from Windows NT to Windows 95. It is not completely
+compatible in the reverse direction, however. Filenames that fit in
+the 8.3 namespace and are written on Windows NT to be lowercase will
+show up as uppercase on Windows 95.
+
+.. note:: Note that the ``start`` and ``size`` values are actually little
+ endian integer values. The descriptions of the fields in this
+ structure are public knowledge and can be found elsewhere.
+
+With the extended FAT system, Microsoft has inserted extra
+directory entries for any files with extended names. (Any name which
+legally fits within the old 8.3 encoding scheme does not have extra
+entries.) I call these extra entries slots. Basically, a slot is a
+specially formatted directory entry which holds up to 13 characters of
+a file's extended name. Think of slots as additional labeling for the
+directory entry of the file to which they correspond. Microsoft
+prefers to refer to the 8.3 entry for a file as its alias and the
+extended slot directory entries as the file name.
+
+The C structure for a slot directory entry follows::
+
+ struct slot { // Up to 13 characters of a long name
+ unsigned char id; // sequence number for slot
+ unsigned char name0_4[10]; // first 5 characters in name
+ unsigned char attr; // attribute byte
+ unsigned char reserved; // always 0
+ unsigned char alias_checksum; // checksum for 8.3 alias
+ unsigned char name5_10[12]; // 6 more characters in name
+ unsigned char start[2]; // starting cluster number
+ unsigned char name11_12[4]; // last 2 characters in name
+ };
+
+
+If the layout of the slots looks a little odd, it's only
+because of Microsoft's efforts to maintain compatibility with old
+software. The slots must be disguised to prevent old software from
+panicking. To this end, a number of measures are taken:
+
+ 1) The attribute byte for a slot directory entry is always set
+ to 0x0f. This corresponds to an old directory entry with
+ attributes of "hidden", "system", "read-only", and "volume
+ label". Most old software will ignore any directory
+ entries with the "volume label" bit set. Real volume label
+ entries don't have the other three bits set.
+
+ 2) The starting cluster is always set to 0, an impossible
+ value for a DOS file.
+
+Because the extended FAT system is backward compatible, it is
+possible for old software to modify directory entries. Measures must
+be taken to ensure the validity of slots. An extended FAT system can
+verify that a slot does in fact belong to an 8.3 directory entry by
+the following:
+
+ 1) Positioning. Slots for a file always immediately proceed
+ their corresponding 8.3 directory entry. In addition, each
+ slot has an id which marks its order in the extended file
+ name. Here is a very abbreviated view of an 8.3 directory
+ entry and its corresponding long name slots for the file
+ "My Big File.Extension which is long"::
+
+ <proceeding files...>
+ <slot #3, id = 0x43, characters = "h is long">
+ <slot #2, id = 0x02, characters = "xtension whic">
+ <slot #1, id = 0x01, characters = "My Big File.E">
+ <directory entry, name = "MYBIGFIL.EXT">
+
+
+ .. note:: Note that the slots are stored from last to first. Slots
+ are numbered from 1 to N. The Nth slot is ``or'ed`` with
+ 0x40 to mark it as the last one.
+
+ 2) Checksum. Each slot has an alias_checksum value. The
+ checksum is calculated from the 8.3 name using the
+ following algorithm::
+
+ for (sum = i = 0; i < 11; i++) {
+ sum = (((sum&1)<<7)|((sum&0xfe)>>1)) + name[i]
+ }
+
+
+ 3) If there is free space in the final slot, a Unicode ``NULL (0x0000)``
+ is stored after the final character. After that, all unused
+ characters in the final slot are set to Unicode 0xFFFF.
+
+Finally, note that the extended name is stored in Unicode. Each Unicode
+character takes either two or four bytes, UTF-16LE encoded.

-USING VFAT
-----------------------------------------------------------------------
-To use the vfat filesystem, use the filesystem type 'vfat'. i.e.
- mount -t vfat /dev/fd0 /mnt
-
-No special partition formatter is required. mkdosfs will work fine
-if you want to format from within Linux.
-
-VFAT MOUNT OPTIONS
-----------------------------------------------------------------------
-uid=### -- Set the owner of all files on this filesystem.
- The default is the uid of current process.
-
-gid=### -- Set the group of all files on this filesystem.
- The default is the gid of current process.
-
-umask=### -- The permission mask (for files and directories, see umask(1)).
- The default is the umask of current process.
-
-dmask=### -- The permission mask for the directory.
- The default is the umask of current process.
-
-fmask=### -- The permission mask for files.
- The default is the umask of current process.
-
-allow_utime=### -- This option controls the permission check of mtime/atime.
-
- 20 - If current process is in group of file's group ID,
- you can change timestamp.
- 2 - Other users can change timestamp.
-
- The default is set from `dmask' option. (If the directory is
- writable, utime(2) is also allowed. I.e. ~dmask & 022)
-
- Normally utime(2) checks current process is owner of
- the file, or it has CAP_FOWNER capability. But FAT
- filesystem doesn't have uid/gid on disk, so normal
- check is too unflexible. With this option you can
- relax it.
-
-codepage=### -- Sets the codepage number for converting to shortname
- characters on FAT filesystem.
- By default, FAT_DEFAULT_CODEPAGE setting is used.
-
-iocharset=<name> -- Character set to use for converting between the
- encoding is used for user visible filename and 16 bit
- Unicode characters. Long filenames are stored on disk
- in Unicode format, but Unix for the most part doesn't
- know how to deal with Unicode.
- By default, FAT_DEFAULT_IOCHARSET setting is used.
-
- There is also an option of doing UTF-8 translations
- with the utf8 option.
-
- NOTE: "iocharset=utf8" is not recommended. If unsure,
- you should consider the following option instead.
-
-utf8=<bool> -- UTF-8 is the filesystem safe version of Unicode that
- is used by the console. It can be enabled or disabled
- for the filesystem with this option.
- If 'uni_xlate' gets set, UTF-8 gets disabled.
- By default, FAT_DEFAULT_UTF8 setting is used.
-
-uni_xlate=<bool> -- Translate unhandled Unicode characters to special
- escaped sequences. This would let you backup and
- restore filenames that are created with any Unicode
- characters. Until Linux supports Unicode for real,
- this gives you an alternative. Without this option,
- a '?' is used when no translation is possible. The
- escape character is ':' because it is otherwise
- illegal on the vfat filesystem. The escape sequence
- that gets used is ':' and the four digits of hexadecimal
- unicode.
-
-nonumtail=<bool> -- When creating 8.3 aliases, normally the alias will
- end in '~1' or tilde followed by some number. If this
- option is set, then if the filename is
- "longfilename.txt" and "longfile.txt" does not
- currently exist in the directory, 'longfile.txt' will
- be the short alias instead of 'longfi~1.txt'.
-
-usefree -- Use the "free clusters" value stored on FSINFO. It'll
- be used to determine number of free clusters without
- scanning disk. But it's not used by default, because
- recent Windows don't update it correctly in some
- case. If you are sure the "free clusters" on FSINFO is
- correct, by this option you can avoid scanning disk.
-
-quiet -- Stops printing certain warning messages.
-

There's a collection of tests that aims to cover the whole functionality of

-To build IGT, start by installing its build dependencies. In Debian-based
-systems::
+Using VKMS to test DRM API
+--------------------------
- # apt-get build-dep intel-gpu-tools
+VKMS is a software-only model of a KMS driver that is useful for testing
+and for running compositors. VKMS aims to enable a virtual display without
+the need for a hardware display capability. These characteristics made VKMS
+a perfect tool for validating the DRM core behavior and also support the
+compositor developer. VKMS makes it possible to test DRM functions in a
+virtual machine without display, simplifying the validation of some of the
+core changes.
-And in Fedora-based systems::
+To Validate changes in DRM API with VKMS, start setting the kernel: make
+sure to enable VKMS module; compile the kernel with the VKMS enabled and
+install it in the target machine. VKMS can be run in a Virtual Machine
+(QEMU, virtme or similar). It's recommended the use of KVM with the minimum
+of 1GB of RAM and four cores.
- # dnf builddep intel-gpu-tools
+It's possible to run the IGT-tests in a VM in two ways:
-Then clone the repository::
+ 1. Use IGT inside a VM
+ 2. Use IGT from the host machine and write the results in a shared directory.
- $ git clone git://anongit.freedesktop.org/drm/igt-gpu-tools
+As follow, there is an example of using a VM with a shared directory with
+the host machine to run igt-tests. As an example it's used virtme::
-Configure the build system and start the build::
+ $ virtme-run --rwdir /path/for/shared_dir --kdir=path/for/kernel/directory --mods=auto
- $ cd igt-gpu-tools && ./autogen.sh && make -j6
+Run the igt-tests in the guest machine, as example it's ran the 'kms_flip'
+tests::
-Download the piglit dependency::
+ $ /path/for/igt-gpu-tools/scripts/run-tests.sh -p -s -t "kms_flip.*" -v
- $ ./scripts/run-tests.sh -d
-
-And run the tests::
-
- $ ./scripts/run-tests.sh -t kms -t core -s
-
-run-tests.sh is a wrapper around piglit that will execute the tests matching
-the -t options. A report in HTML format will be available in
-./results/html/index.html. Results can be compared with piglit.
+In this example, instead of build the igt_runner, Piglit is used
+(-p option); it's created html summary of the tests results and it's saved
+in the folder "igt-gpu-tools/results"; it's executed only the igt-tests

several ways to achieve this, depending on the context and requirements.
-Method 1a: Declare the I2C devices by bus number
-------------------------------------------------
+Method 1: Declare the I2C devices statically
+--------------------------------------------
This method is appropriate when the I2C bus is a system bus as is the case
-for many embedded systems. On such systems, each I2C bus has a number
-which is known in advance. It is thus possible to pre-declare the I2C
-devices which live on this bus. This is done with an array of struct
-i2c_board_info which is registered by calling i2c_register_board_info().
+for many embedded systems. On such systems, each I2C bus has a number which
+is known in advance. It is thus possible to pre-declare the I2C devices
+which live on this bus.
+
+This information is provided to the kernel in a different way on different
+architectures: device tree, ACPI or board files.
+
+When the I2C bus in question is registered, the I2C devices will be
+instantiated automatically by i2c-core. The devices will be automatically
+unbound and destroyed when the I2C bus they sit on goes away (if ever).
+
+
+Declare the I2C devices via devicetree
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+On platforms using devicetree, the declaration of I2C devices is done in
+subnodes of the master controller.
+
+Example::
+
+ i2c1: i2c@400a0000 {
+ /* ... master properties skipped ... */
+ clock-frequency = <100000>;
+
+ flash@50 {
+ compatible = "atmel,24c256";

+ pca9532: gpio@60 {
+ compatible = "nxp,pca9532";
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x60>;
+ };
+ };
+
+Here, two devices are attached to the bus using a speed of 100kHz. For
+additional properties which might be needed to set up the device, please refer
+to its devicetree documentation in Documentation/devicetree/bindings/.
+
+
+Declare the I2C devices via ACPI
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ACPI can also describe I2C devices. There is special documentation for this
+which is currently located at :doc:`../firmware-guide/acpi/enumeration`.
+
+
+Declare the I2C devices in board files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In many embedded architectures, devicetree has replaced the old hardware
+description based on board files, but the latter are still used in old
+code. Instantiating I2C devices via board files is done with an array of
+struct i2c_board_info which is registered by calling
+i2c_register_board_info().

The above code declares 3 devices on I2C bus 1, including their respective

-==========================
-GigaSet 307x Device Driver
-==========================
-
-1. Requirements
-=================
-
-1.1. Hardware
--------------
-
- This driver supports the connection of the Gigaset 307x/417x family of
- ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB
- connection. The following devices are reported to be compatible:
-
- Bases:
- - Siemens Gigaset 3070/3075 isdn
- - Siemens Gigaset 4170/4175 isdn
- - Siemens Gigaset SX205/255
- - Siemens Gigaset SX353
- - T-Com Sinus 45 [AB] isdn
- - T-Com Sinus 721X[A] [SE]
- - Vox Chicago 390 ISDN (KPN Telecom)
-
- RS232 data boxes:
- - Siemens Gigaset M101 Data
- - T-Com Sinus 45 Data 1
-
- USB data boxes:
- - Siemens Gigaset M105 Data
- - Siemens Gigaset USB Adapter DECT
- - T-Com Sinus 45 Data 2
- - T-Com Sinus 721 data
- - Chicago 390 USB (KPN)
-
- See also http://www.erbze.info/sinus_gigaset.htm
- (archived at https://web.archive.org/web/20100717020421/http://www.erbze.info:80/sinus_gigaset.htm ) and
- http://gigaset307x.sourceforge.net/
-
- We had also reports from users of Gigaset M105 who could use the drivers
- with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.5.)
- If you have another device that works with our driver, please let us know.
-
- Chances of getting an USB device to work are good if the output of::
-
- lsusb
-
- at the command line contains one of the following::
-
- ID 0681:0001
- ID 0681:0002
- ID 0681:0009
- ID 0681:0021
- ID 0681:0022
-
-1.2. Software
--------------
-
- The driver works with the Kernel CAPI subsystem and can be used with any
- software which is able to use CAPI 2.0 for ISDN connections (voice or data).
-
- There are some user space tools available at
- https://sourceforge.net/projects/gigaset307x/
- which provide access to additional device specific functions like SMS,
- phonebook or call journal.
-
-
-2. How to use the driver
-==========================
-
-2.1. Modules
-------------
-
- For the devices to work, the proper kernel modules have to be loaded.
- This normally happens automatically when the system detects the USB
- device (base, M105) or when the line discipline is attached (M101). It
- can also be triggered manually using the modprobe(8) command, for example
- for troubleshooting or to pass module parameters.
-
- The module ser_gigaset provides a serial line discipline N_GIGASET_M101
- which uses the regular serial port driver to access the device, and must
- therefore be attached to the serial device to which the M101 is connected.
- The ldattach(8) command (included in util-linux-ng release 2.14 or later)
- can be used for that purpose, for example::
-
- ldattach GIGASET_M101 /dev/ttyS1
-
- This will open the device file, attach the line discipline to it, and
- then sleep in the background, keeping the device open so that the line
- discipline remains active. To deactivate it, kill the daemon, for example
- with::
-
- killall ldattach
-
- before disconnecting the device. To have this happen automatically at
- system startup/shutdown on an LSB compatible system, create and activate
- an appropriate LSB startup script /etc/init.d/gigaset. (The init name
- 'gigaset' is officially assigned to this project by LANANA.)
- Alternatively, just add the 'ldattach' command line to /etc/rc.local.
-
- The modules accept the following parameters:
-
- =============== ========== ==========================================
- Module Parameter Meaning
-
- gigaset debug debug level (see section 3.2.)
-
- startmode initial operation mode (see section 2.5.):
- bas_gigaset ) 1=CAPI (default), 0=Unimodem
- ser_gigaset )
- usb_gigaset ) cidmode initial Call-ID mode setting (see section
- 2.5.): 1=on (default), 0=off
-
- =============== ========== ==========================================
-
- Depending on your distribution you may want to create a separate module
- configuration file like /etc/modprobe.d/gigaset.conf for these.
-
-2.2. Device nodes for user space programs
------------------------------------------
-
- The device can be accessed from user space (eg. by the user space tools
- mentioned in 1.2.) through the device nodes:
-
- - /dev/ttyGS0 for M101 (RS232 data boxes)
- - /dev/ttyGU0 for M105 (USB data boxes)
- - /dev/ttyGB0 for the base driver (direct USB connection)
-
- If you connect more than one device of a type, they will get consecutive
- device nodes, eg. /dev/ttyGU1 for a second M105.
-
- You can also set a "default device" for the user space tools to use when
- no device node is given as parameter, by creating a symlink /dev/ttyG to
- one of them, eg.::
-
- ln -s /dev/ttyGB0 /dev/ttyG
-
- The devices accept the following device specific ioctl calls
- (defined in gigaset_dev.h):
-
- ``ioctl(int fd, GIGASET_REDIR, int *cmd);``
-
- If cmd==1, the device is set to be controlled exclusively through the
- character device node; access from the ISDN subsystem is blocked.
-
- If cmd==0, the device is set to be used from the ISDN subsystem and does
- not communicate through the character device node.
-
- ``ioctl(int fd, GIGASET_CONFIG, int *cmd);``
-
- (ser_gigaset and usb_gigaset only)
-
- If cmd==1, the device is set to adapter configuration mode where commands
- are interpreted by the M10x DECT adapter itself instead of being
- forwarded to the base station. In this mode, the device accepts the
- commands described in Siemens document "AT-Kommando Alignment M10x Data"
- for setting the operation mode, associating with a base station and
- querying parameters like field strengh and signal quality.
-
- Note that there is no ioctl command for leaving adapter configuration
- mode and returning to regular operation. In order to leave adapter
- configuration mode, write the command ATO to the device.
-
- ``ioctl(int fd, GIGASET_BRKCHARS, unsigned char brkchars[6]);``
-
- (usb_gigaset only)
-
- Set the break characters on an M105's internal serial adapter to the six
- bytes stored in brkchars[]. Unused bytes should be set to zero.
-
- ioctl(int fd, GIGASET_VERSION, unsigned version[4]);
- Retrieve version information from the driver. version[0] must be set to
- one of:
-
- - GIGVER_DRIVER: retrieve driver version
- - GIGVER_COMPAT: retrieve interface compatibility version
- - GIGVER_FWBASE: retrieve the firmware version of the base
-
- Upon return, version[] is filled with the requested version information.
-
-2.3. CAPI
----------
-
- The devices will show up as CAPI controllers as soon as the
- corresponding driver module is loaded, and can then be used with
- CAPI 2.0 kernel and user space applications. For user space access,
- the module capi.ko must be loaded.
-
- Most distributions handle loading and unloading of the various CAPI
- modules automatically via the command capiinit(1) from the capi4k-utils
- package or a similar mechanism. Note that capiinit(1) cannot unload the
- Gigaset drivers because it doesn't support more than one module per
- driver.
-
-2.5. Unimodem mode
-------------------
-
- In this mode the device works like a modem connected to a serial port
- (the /dev/ttyGU0, ... mentioned above) which understands the commands::
-
- ATZ init, reset
- => OK or ERROR
- ATD
- ATDT dial
- => OK, CONNECT,
- BUSY,
- NO DIAL TONE,
- NO CARRIER,
- NO ANSWER
- <pause>+++<pause> change to command mode when connected
- ATH hangup
-
- You can use some configuration tool of your distribution to configure this
- "modem" or configure pppd/wvdial manually. There are some example ppp
- configuration files and chat scripts in the gigaset-VERSION/ppp directory
- in the driver packages from https://sourceforge.net/projects/gigaset307x/.
- Please note that the USB drivers are not able to change the state of the
- control lines. This means you must use "Stupid Mode" if you are using
- wvdial or you should use the nocrtscts option of pppd.
- You must also assure that the ppp_async module is loaded with the parameter
- flag_time=0. You can do this e.g. by adding a line like::
-
- options ppp_async flag_time=0
-
- to an appropriate module configuration file, like::
-
- /etc/modprobe.d/gigaset.conf.
-
- Unimodem mode is needed for making some devices [e.g. SX100] work which
- do not support the regular Gigaset command set. If debug output (see
- section 3.2.) shows something like this when dialing::
-
- CMD Received: ERROR
- Available Params: 0
- Connection State: 0, Response: -1
- gigaset_process_response: resp_code -1 in ConState 0 !
- Timeout occurred
-
- then switching to unimodem mode may help.
-
- If you have installed the command line tool gigacontr, you can enter
- unimodem mode using::
-
- gigacontr --mode unimodem
-
- You can switch back using::
-
- gigacontr --mode isdn
-
- You can also put the driver directly into Unimodem mode when it's loaded,
- by passing the module parameter startmode=0 to the hardware specific
- module, e.g.::
-
- modprobe usb_gigaset startmode=0
-
- or by adding a line like::
-
- options usb_gigaset startmode=0
-
- to an appropriate module configuration file, like::
-
- /etc/modprobe.d/gigaset.conf
-
-2.6. Call-ID (CID) mode
------------------------
-
- Call-IDs are numbers used to tag commands to, and responses from, the
- Gigaset base in order to support the simultaneous handling of multiple
- ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem
- mode"). Without Call-IDs (in Unimodem mode), only a very limited set of
- functions is available. It allows outgoing data connections only, but
- does not signal incoming calls or other base events.
-
- DECT cordless data devices (M10x) permanently occupy the cordless
- connection to the base while Call-IDs are activated. As the Gigaset
- bases only support one DECT data connection at a time, this prevents
- other DECT cordless data devices from accessing the base.
-
- During active operation, the driver switches to the necessary mode
- automatically. However, for the reasons above, the mode chosen when
- the device is not in use (idle) can be selected by the user.
-
- - If you want to receive incoming calls, you can use the default
- settings (CID mode).
- - If you have several DECT data devices (M10x) which you want to use
- in turn, select Unimodem mode by passing the parameter "cidmode=0" to
- the appropriate driver module (ser_gigaset or usb_gigaset).
-
- If you want both of these at once, you are out of luck.
-
- You can also use the tty class parameter "cidmode" of the device to
- change its CID mode while the driver is loaded, eg.::
-
- echo 0 > /sys/class/tty/ttyGU0/cidmode
-
-2.7. Dialing Numbers
---------------------
-provided by an application for dialing out must
- be a public network number according to the local dialing plan, without
- any dial prefix for getting an outside line.
-
- Internal calls can be made by providing an internal extension number
- prefixed with ``**`` (two asterisks) as the called party number. So to dial
- eg. the first registered DECT handset, give ``**11`` as the called party
- number. Dialing ``***`` (three asterisks) calls all extensions
- simultaneously (global call).
-
- Unimodem mode does not support internal calls.
-
-2.8. Unregistered Wireless Devices (M101/M105)
-----------------------------------------------
-
- The main purpose of the ser_gigaset and usb_gigaset drivers is to allow
- the M101 and M105 wireless devices to be used as ISDN devices for ISDN
- connections through a Gigaset base. Therefore they assume that the device
- is registered to a DECT base.
-
- If the M101/M105 device is not registered to a base, initialization of
- the device fails, and a corresponding error message is logged by the
- driver. In that situation, a restricted set of functions is available
- which includes, in particular, those necessary for registering the device
- to a base or for switching it between Fixed Part and Portable Part
- modes. See the gigacontr(8) manpage for details.
-
-3. Troubleshooting
-====================
-
-3.1. Solutions to frequently reported problems
-----------------------------------------------
-
- Problem:
- You have a slow provider and isdn4linux gives up dialing too early.
- Solution:
- Load the isdn module using the dialtimeout option. You can do this e.g.
- by adding a line like::
-
- options isdn dialtimeout=15
-
- to /etc/modprobe.d/gigaset.conf or a similar file.
-
- Problem:
- The isdnlog program emits error messages or just doesn't work.
- Solution:
- Isdnlog supports only the HiSax driver. Do not attempt to use it with
- other drivers such as Gigaset.
-
- Problem:
- You have two or more DECT data adapters (M101/M105) and only the
- first one you turn on works.
- Solution:
- Select Unimodem mode for all DECT data adapters. (see section 2.5.)
-
- Problem:
- Messages like this::
-
- usb_gigaset 3-2:1.0: Could not initialize the device.
-
- appear in your syslog.
- Solution:
- Check whether your M10x wireless device is correctly registered to the
- Gigaset base. (see section 2.7.)
-
-3.2. Telling the driver to provide more information
----------------------------------------------------
- Building the driver with the "Gigaset debugging" kernel configuration
- option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional
- information useful for debugging.
-
- You can control the amount of debugging information the driver produces by
- writing an appropriate value to /sys/module/gigaset/parameters/debug,
- e.g.::
-
- echo 0 > /sys/module/gigaset/parameters/debug
-
- switches off debugging output completely,
-
- ::
-
- echo 0x302020 > /sys/module/gigaset/parameters/debug
-
- enables a reasonable set of debugging output messages. These values are
- bit patterns where every bit controls a certain type of debugging output.
- See the constants DEBUG_* in the source file gigaset.h for details.
-
- The initial value can be set using the debug parameter when loading the
- module "gigaset", e.g. by adding a line::
-
- options gigaset debug=0
-
- to your module configuration file, eg. /etc/modprobe.d/gigaset.conf
-
- Generated debugging information can be found
- - as output of the command::
-
- dmesg
-
- - in system log files written by your syslog daemon, usually
- in /var/log/, e.g. /var/log/messages.
-
-3.3. Reporting problems and bugs
---------------------------------
- If you can't solve problems with the driver on your own, feel free to
- use one of the forums, bug trackers, or mailing lists on
-
- https://sourceforge.net/projects/gigaset307x
-
- or write an electronic mail to the maintainers.
-
- Try to provide as much information as possible, such as
-
- - distribution
- - kernel version (uname -r)
- - gcc version (gcc --version)
- - hardware architecture (uname -m, ...)
- - type and firmware version of your device (base and wireless module,
- if any)
- - output of "lsusb -v" (if using an USB device)
- - error messages
- - relevant system log messages (it would help if you activate debug
- output as described in 3.2.)
-
- For help with general configuration problems not specific to our driver,
- such as isdn4linux and network configuration issues, please refer to the
- appropriate forums and newsgroups.
-
-3.4. Reporting problem solutions
---------------------------------
- If you solved a problem with our drivers, wrote startup scripts for your
- distribution, ... feel free to contact us (using one of the places
- mentioned in 3.3.). We'd like to add scripts, hints, documentation
- to the driver and/or the project web page.

-
-1. About the driver
-===================
-
- The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
- PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
- enable ISDN support in the kernel config and support for HYSDN cards in
- the active cards submenu. The driver may only be compiled and used if
- support for loadable modules and the process filesystem have been enabled.
-
- These cards provide two different interfaces to the kernel. Without the
- optional CAPI 2.0 support, they register as ethernet card. IP-routing
- to a ISDN-destination is performed on the card itself. All necessary
- handlers for various protocols like ppp and others as well as config info
- and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
-
- With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0
- compliant devices with either CAPI 2.0 applications
- (check isdn4k-utils) or -using the capidrv module- as a regular
- isdn4linux device. This is done via the same mechanism as with the
- active AVM cards and in fact uses the same module.
-
-
-2. Loading/Unloading the driver
-===============================
-
- The module has no command line parameters and auto detects up to 10 cards
- in the id-range 0-9.
- If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
- subdir need to be closed and all ethernet interfaces allocated by this
- driver must be shut down. Otherwise the module counter will avoid a module
- unload.
-
- If you are using the CAPI 2.0-interface, make sure to load/modprobe the
- kernelcapi-module first.
-
- If you plan to use the capidrv-link to isdn4linux, make sure to load
- capidrv.o after all modules using this driver (i.e. after hysdn and
- any avm-specific modules).
-
-3. Entries in the /proc filesystem
-==================================
-
- When the module has been loaded it adds the directory hysdn in the
- /proc/net tree. This directory contains exactly 2 file entries for each
- card. One is called cardconfX and the other cardlogX, where X is the
- card id number from 0 to 9.
- The cards are numbered in the order found in the PCI config data.
-
-4. The /proc/net/hysdn/cardconfX file
-=====================================
-
- This file may be read to get by everyone to get info about the cards type,
- actual state, available features and used resources.
- The first 3 entries (id, bus and slot) are PCI info fields, the following
- type field gives the information about the cards type:
-
- - 4 -> Ergo card (server card with 2 b-chans)
- - 5 -> Metro card (server card with 4 or 8 b-chans)
- - 6 -> Champ card (client card with 2 b-chans)
-
- The following 3 fields show the hardware assignments for irq, iobase and the
- dual ported memory (dp-mem).
-
- The fields b-chans and fax-chans announce the available card resources of
- this types for the user.
-
- The state variable indicates the actual drivers state for this card with the
- following assignments.
-
- - 0 -> card has not been booted since driver load
- - 1 -> card booting is actually in progess
- - 2 -> card is in an error state due to a previous boot failure
- - 3 -> card is booted and active
-
- And the last field (device) shows the name of the ethernet device assigned
- to this card. Up to the first successful boot this field only shows a -
- to tell that no net device has been allocated up to now. Once a net device
- has been allocated it remains assigned to this card, even if a card is
- rebooted and an boot error occurs.
-
- Writing to the cardconfX file boots the card or transfers config lines to
- the cards firmware. The type of data is automatically detected when the
- first data is written. Only root has write access to this file.
- The firmware boot files are normally called hyclient.pof for client cards
- and hyserver.pof for server cards.
- After successfully writing the boot file, complete config files or single
- config lines may be copied to this file.
- If an error occurs the return value given to the writing process has the
- following additional codes (decimal):
-
- ==== ============================================
- 1000 Another process is currently bootng the card
- 1001 Invalid firmware header
- 1002 Boards dual-port RAM test failed
- 1003 Internal firmware handler error
- 1004 Boot image size invalid
- 1005 First boot stage (bootstrap loader) failed
- 1006 Second boot stage failure
- 1007 Timeout waiting for card ready during boot
- 1008 Operation only allowed in booted state
- 1009 Config line too long
- 1010 Invalid channel number
- 1011 Timeout sending config data
- ==== ============================================
-
- Additional info about error reasons may be fetched from the log output.
-
-5. The /proc/net/hysdn/cardlogX file
-====================================
-
- The cardlogX file entry may be opened multiple for reading by everyone to
- get the cards and drivers log data. Card messages always start with the
- keyword LOG. All other lines are output from the driver.
- The driver log data may be redirected to the syslog by selecting the
- appropriate bitmask. The cards log messages will always be send to this
- interface but never to the syslog.
-
- A root user may write a decimal or hex (with 0x) value t this file to select
- desired output options. As mentioned above the cards log dat is always
- written to the cardlog file independent of the following options only used
- to check and debug the driver itself:
-
- For example::
-
- echo "0x34560078" > /proc/net/hysdn/cardlog0
-
- to output the hex log mask 34560078 for card 0.
-
- The written value is regarded as an unsigned 32-Bit value, bit ored for
- desired output. The following bits are already assigned:
-
- ========== ============================================================
- 0x80000000 All driver log data is alternatively via syslog
- 0x00000001 Log memory allocation errors
- 0x00000010 Firmware load start and close are logged
- 0x00000020 Log firmware record parser
- 0x00000040 Log every firmware write actions
- 0x00000080 Log all card related boot messages
- 0x00000100 Output all config data sent for debugging purposes
- 0x00000200 Only non comment config lines are shown wth channel
- 0x00000400 Additional conf log output
- 0x00001000 Log the asynchronous scheduler actions (config and log)
- 0x00100000 Log all open and close actions to /proc/net/hysdn/card files
- 0x00200000 Log all actions from /proc file entries
- 0x00010000 Log network interface init and deinit
- ========== ============================================================

-The cx18 driver
-===============
-
-.. note::
-
- This documentation is outdated.
-
-Some notes regarding the cx18 driver for the Conexant CX23418 MPEG
-encoder chip:
-
-1) Currently supported are:
-
- - Hauppauge HVR-1600
- - Compro VideoMate H900
- - Yuan MPC718
- - Conexant Raptor PAL/SECAM devkit
-
-2) Some people have problems getting the i2c bus to work.
- The symptom is that the eeprom cannot be read and the card is
- unusable. This is probably fixed, but if you have problems
- then post to the video4linux or ivtv-users mailing list.
-
-3) VBI (raw or sliced) has not yet been implemented.
-
-4) MPEG indexing is not yet implemented.
-
-5) The driver is still a bit rough around the edges, this should
- improve over time.

-Power Management Interface for System Sleep
-===========================================
-
-Copyright (c) 2016 Intel Corp., Rafael J. Wysocki <rafael.j.wysocki@intel.com>
-
-The power management subsystem provides userspace with a unified sysfs interface
-for system sleep regardless of the underlying system architecture or platform.
-The interface is located in the /sys/power/ directory (assuming that sysfs is
-mounted at /sys).
-
-/sys/power/state is the system sleep state control file.
-
-Reading from it returns a list of supported sleep states, encoded as:
-
-- 'freeze' (Suspend-to-Idle)
-- 'standby' (Power-On Suspend)
-- 'mem' (Suspend-to-RAM)
-- 'disk' (Suspend-to-Disk)
-
-Suspend-to-Idle is always supported. Suspend-to-Disk is always supported
-too as long the kernel has been configured to support hibernation at all
-(ie. CONFIG_HIBERNATION is set in the kernel configuration file). Support
-for Suspend-to-RAM and Power-On Suspend depends on the capabilities of the
-platform.
-
-If one of the strings listed in /sys/power/state is written to it, the system
-will attempt to transition into the corresponding sleep state. Refer to
-Documentation/admin-guide/pm/sleep-states.rst for a description of each of
-those states.
-
-/sys/power/disk controls the operating mode of hibernation (Suspend-to-Disk).
-Specifically, it tells the kernel what to do after creating a hibernation image.
-
-Reading from it returns a list of supported options encoded as:
-
-- 'platform' (put the system into sleep using a platform-provided method)
-- 'shutdown' (shut the system down)
-- 'reboot' (reboot the system)
-- 'suspend' (trigger a Suspend-to-RAM transition)
-- 'test_resume' (resume-after-hibernation test mode)
-
-The currently selected option is printed in square brackets.
-
-The 'platform' option is only available if the platform provides a special
-mechanism to put the system to sleep after creating a hibernation image (ACPI
-does that, for example). The 'suspend' option is available if Suspend-to-RAM
-is supported. Refer to Documentation/power/basic-pm-debugging.rst for the
-description of the 'test_resume' option.
-
-To select an option, write the string representing it to /sys/power/disk.
-
-/sys/power/image_size controls the size of hibernation images.
-
-It can be written a string representing a non-negative integer that will be
-used as a best-effort upper limit of the image size, in bytes. The hibernation
-core will do its best to ensure that the image size will not exceed that number.
-However, if that turns out to be impossible to achieve, a hibernation image will
-still be created and its size will be as small as possible. In particular,
-writing '0' to this file will enforce hibernation images to be as small as
-possible.
-
-Reading from this file returns the current image size limit, which is set to
-around 2/5 of available RAM by default.
-
-/sys/power/pm_trace controls the PM trace mechanism saving the last suspend
-or resume event point in the RTC across reboots.
-
-It helps to debug hard lockups or reboots due to device driver failures that
-occur during system suspend or resume (which is more common) more effectively.
-
-If /sys/power/pm_trace contains '1', the fingerprint of each suspend/resume
-event point in turn will be stored in the RTC memory (overwriting the actual
-RTC information), so it will survive a system crash if one occurs right after
-storing it and it can be used later to identify the driver that caused the crash
-to happen (see Documentation/power/s2ram.rst for more information).
-
-Initially it contains '0' which may be changed to '1' by writing a string
-representing a nonzero integer into it.

+IMC (In-Memory Collection Counters)
+===================================
+
+Anju T Sudhakar, 10 May 2019
+
+.. contents::
+ :depth: 3
+
+
+Basic overview
+==============
+
+IMC (In-Memory collection counters) is a hardware monitoring facility that
+collects large numbers of hardware performance events at Nest level (these are
+on-chip but off-core), Core level and Thread level.
+
+The Nest PMU counters are handled by a Nest IMC microcode which runs in the OCC
+(On-Chip Controller) complex. The microcode collects the counter data and moves
+the nest IMC counter data to memory.
+
+The Core and Thread IMC PMU counters are handled in the core. Core level PMU
+counters give us the IMC counters' data per core and thread level PMU counters
+give us the IMC counters' data per CPU thread.
+
+OPAL obtains the IMC PMU and supported events information from the IMC Catalog
+and passes on to the kernel via the device tree. The event's information
+contains:
+
+- Event name
+- Event Offset
+- Event description
+
+and possibly also:
+
+- Event scale
+- Event unit
+
+Some PMUs may have a common scale and unit values for all their supported
+events. For those cases, the scale and unit properties for those events must be
+inherited from the PMU.
+
+The event offset in the memory is where the counter data gets accumulated.
+
+IMC catalog is available at:
+ https://github.com/open-power/ima-catalog
+
+The kernel discovers the IMC counters information in the device tree at the
+`imc-counters` device node which has a compatible field
+`ibm,opal-in-memory-counters`. From the device tree, the kernel parses the PMUs
+and their event's information and register the PMU and its attributes in the
+kernel.
+
+IMC example usage
+=================
+
+.. code-block:: sh
+
+ # perf list
+ [...]
+ nest_mcs01/PM_MCS01_64B_RD_DISP_PORT01/ [Kernel PMU event]

+ thread_imc/CPM_1THRD_NON_IDLE_INST/ [Kernel PMU event]
+
+To see per chip data for nest_mcs0/PM_MCS_DOWN_128B_DATA_XFER_MC0/:
+
+.. code-block:: sh
+
+ # ./perf stat -e "nest_mcs01/PM_MCS01_64B_WR_DISP_PORT01/" -a --per-socket
+
+To see non-idle instructions for core 0:
+
+.. code-block:: sh
+
+ # ./perf stat -e "core_imc/CPM_NON_IDLE_INST/" -C 0 -I 1000
+
+To see non-idle instructions for a "make":
+
+.. code-block:: sh
+
+ # ./perf stat -e "thread_imc/CPM_NON_IDLE_PCYC/" make
+
+
+IMC Trace-mode
+===============
+
+POWER9 supports two modes for IMC which are the Accumulation mode and Trace
+mode. In Accumulation mode, event counts are accumulated in system Memory.
+Hypervisor then reads the posted counts periodically or when requested. In IMC
+Trace mode, the 64 bit trace SCOM value is initialized with the event
+information. The CPMCxSEL and CPMC_LOAD in the trace SCOM, specifies the event
+to be monitored and the sampling duration. On each overflow in the CPMCxSEL,
+hardware snapshots the program counter along with event counts and writes into
+memory pointed by LDBAR.
+
+LDBAR is a 64 bit special purpose per thread register, it has bits to indicate
+whether hardware is configured for accumulation or trace mode.
+
+LDBAR Register Layout
+---------------------
+
+ +-------+----------------------+
+ | 0 | Enable/Disable |
+ +-------+----------------------+
+ | 1 | 0: Accumulation Mode |
+ | +----------------------+
+ | | 1: Trace Mode |
+ +-------+----------------------+
+ | 2:3 | Reserved |
+ +-------+----------------------+
+ | 4-6 | PB scope |
+ +-------+----------------------+
+ | 7 | Reserved |
+ +-------+----------------------+
+ | 8:50 | Counter Address |
+ +-------+----------------------+
+ | 51:63 | Reserved |
+ +-------+----------------------+
+
+TRACE_IMC_SCOM bit representation
+---------------------------------
+
+ +-------+------------+
+ | 0:1 | SAMPSEL |
+ +-------+------------+
+ | 2:33 | CPMC_LOAD |
+ +-------+------------+
+ | 34:40 | CPMC1SEL |
+ +-------+------------+
+ | 41:47 | CPMC2SEL |
+ +-------+------------+
+ | 48:50 | BUFFERSIZE |
+ +-------+------------+
+ | 51:63 | RESERVED |
+ +-------+------------+
+
+CPMC_LOAD contains the sampling duration. SAMPSEL and CPMCxSEL determines the
+event to count. BUFFERSIZE indicates the memory range. On each overflow,
+hardware snapshots the program counter along with event counts and updates the
+memory and reloads the CMPC_LOAD value for the next sampling duration. IMC
+hardware does not support exceptions, so it quietly wraps around if memory
+buffer reaches the end.
+
+*Currently the event monitored for trace-mode is fixed as cycle.*
+
+Trace IMC example usage
+=======================
+
+.. code-block:: sh
+
+ # perf list
+ [....]
+ trace_imc/trace_cycles/ [Kernel PMU event]
+
+To record an application/process with trace-imc event:
+
+.. code-block:: sh
+
+ # perf record -e trace_imc/trace_cycles/ yes > /dev/null
+ [ perf record: Woken up 1 times to write data ]
+ [ perf record: Captured and wrote 0.012 MB perf.data (21 samples) ]
+
+The `perf.data` generated, can be read using perf report.
+
+Benefits of using IMC trace-mode
+================================
+
+PMI (Performance Monitoring Interrupts) interrupt handling is avoided, since IMC
+trace mode snapshots the program counter and updates to the memory. And this
+also provide a way for the operating system to do instruction sampling in real
+time without PMI processing overhead.
+
+Performance data using `perf top` with and without trace-imc event.
+
+PMI interrupts count when `perf top` command is executed without trace-imc event.
+
+.. code-block:: sh
+
+ # grep PMI /proc/interrupts
+ PMI: 0 0 0 0 Performance monitoring interrupts
+ # ./perf top
+ ...
+ # grep PMI /proc/interrupts
+ PMI: 39735 8710 17338 17801 Performance monitoring interrupts
+ # ./perf top -e trace_imc/trace_cycles/
+ ...
+ # grep PMI /proc/interrupts
+ PMI: 39735 8710 17338 17801 Performance monitoring interrupts
+
+
+That is, the PMI interrupt counts do not increment when using the `trace_imc` event.

+===========================
+Hypercall Op-codes (hcalls)
+===========================
+
+Overview
+=========
+
+Virtualization on 64-bit Power Book3S Platforms is based on the PAPR
+specification [1]_ which describes the run-time environment for a guest
+operating system and how it should interact with the hypervisor for
+privileged operations. Currently there are two PAPR compliant hypervisors:
+
+- **IBM PowerVM (PHYP)**: IBM's proprietary hypervisor that supports AIX,
+ IBM-i and Linux as supported guests (termed as Logical Partitions
+ or LPARS). It supports the full PAPR specification.
+
+- **Qemu/KVM**: Supports PPC64 linux guests running on a PPC64 linux host.
+ Though it only implements a subset of PAPR specification called LoPAPR [2]_.
+
+On PPC64 arch a guest kernel running on top of a PAPR hypervisor is called
+a *pSeries guest*. A pseries guest runs in a supervisor mode (HV=0) and must
+issue hypercalls to the hypervisor whenever it needs to perform an action
+that is hypervisor priviledged [3]_ or for other services managed by the
+hypervisor.
+
+Hence a Hypercall (hcall) is essentially a request by the pseries guest
+asking hypervisor to perform a privileged operation on behalf of the guest. The
+guest issues a with necessary input operands. The hypervisor after performing
+the privilege operation returns a status code and output operands back to the
+guest.
+
+HCALL ABI
+=========
+The ABI specification for a hcall between a pseries guest and PAPR hypervisor
+is covered in section 14.5.3 of ref [2]_. Switch to the Hypervisor context is
+done via the instruction **HVCS** that expects the Opcode for hcall is set in *r3*
+and any in-arguments for the hcall are provided in registers *r4-r12*. If values
+have to be passed through a memory buffer, the data stored in that buffer should be
+in Big-endian byte order.
+
+Once control is returns back to the guest after hypervisor has serviced the
+'HVCS' instruction the return value of the hcall is available in *r3* and any
+out values are returned in registers *r4-r12*. Again like in case of in-arguments,
+any out values stored in a memory buffer will be in Big-endian byte order.
+
+Powerpc arch code provides convenient wrappers named **plpar_hcall_xxx** defined
+in a arch specific header [4]_ to issue hcalls from the linux kernel
+running as pseries guest.
+
+Register Conventions
+====================
+
+Any hcall should follow same register convention as described in section 2.2.1.1
+of "64-Bit ELF V2 ABI Specification: Power Architecture"[5]_. Table below
+summarizes these conventions:

+ | | <----> | | | User |

+ | PAPR | Index +---------+
+ DR2 | Hypervisor | | |
+ +--+ | | <-----> | Kernel |
+ | | <----> | | Hcall | |
+ +--+ DRC2 +------------+ +---------+
+
+PAPR hypervisor terms shared hardware resources like PCI devices, NVDIMMs etc
+available for use by LPARs as Dynamic Resource (DR). When a DR is allocated to
+an LPAR, PHYP creates a data-structure called Dynamic Resource Connector (DRC)
+to manage LPAR access. An LPAR refers to a DRC via an opaque 32-bit number
+called DRC-Index. The DRC-index value is provided to the LPAR via device-tree
+where its present as an attribute in the device tree node associated with the
+DR.
+
+HCALL Return-values
+===================
+
+After servicing the hcall, hypervisor sets the return-value in *r3* indicating
+success or failure of the hcall. In case of a failure an error code indicates
+the cause for error. These codes are defined and documented in arch specific
+header [4]_.
+
+In some cases a hcall can potentially take a long time and need to be issued
+multiple times in order to be completely serviced. These hcalls will usually
+accept an opaque value *continue-token* within there argument list and a
+return value of *H_CONTINUE* indicates that hypervisor hasn't still finished
+servicing the hcall yet.
+
+To make such hcalls the guest need to set *continue-token == 0* for the
+initial call and use the hypervisor returned value of *continue-token*
+for each subsequent hcall until hypervisor returns a non *H_CONTINUE*
+return value.
+
+HCALL Op-codes
+==============
+
+Below is a partial list of HCALLs that are supported by PHYP. For the
+corresponding opcode values please look into the arch specific header [4]_:
+
+**H_SCM_READ_METADATA**
+
+| Input: *drcIndex, offset, buffer-address, numBytesToRead*
+| Out: *numBytesRead*
+| Return Value: *H_Success, H_Parameter, H_P2, H_P3, H_Hardware*
+
+Given a DRC Index of an NVDIMM, read N-bytes from the the metadata area
+associated with it, at a specified offset and copy it to provided buffer.
+The metadata area stores configuration information such as label information,
+bad-blocks etc. The metadata area is located out-of-band of NVDIMM storage
+area hence a separate access semantics is provided.
+
+**H_SCM_WRITE_METADATA**
+
+| Input: *drcIndex, offset, data, numBytesToWrite*
+| Out: *None*
+| Return Value: *H_Success, H_Parameter, H_P2, H_P4, H_Hardware*
+
+Given a DRC Index of an NVDIMM, write N-bytes to the metadata area
+associated with it, at the specified offset and from the provided buffer.
+
+**H_SCM_BIND_MEM**
+
+| Input: *drcIndex, startingScmBlockIndex, numScmBlocksToBind,*
+| *targetLogicalMemoryAddress, continue-token*
+| Out: *continue-token, targetLogicalMemoryAddress, numScmBlocksToBound*
+| Return Value: *H_Success, H_Parameter, H_P2, H_P3, H_P4, H_Overlap,*
+| *H_Too_Big, H_P5, H_Busy*
+
+Given a DRC-Index of an NVDIMM, map a continuous SCM blocks range
+*(startingScmBlockIndex, startingScmBlockIndex+numScmBlocksToBind)* to the guest
+at *targetLogicalMemoryAddress* within guest physical address space. In
+case *targetLogicalMemoryAddress == 0xFFFFFFFF_FFFFFFFF* then hypervisor
+assigns a target address to the guest. The HCALL can fail if the Guest has
+an active PTE entry to the SCM block being bound.

+

+

+
+Description
+~~~~~~~~~~~
+
+ Abort the process of securing a virtual machine. This call must
+ be made after a prior call to ``H_SVM_INIT_START`` hypercall and
+ before a call to ``H_SVM_INIT_DONE``.
+
+ On entry into this hypercall the non-volatile GPRs and FPRs are
+ expected to contain the values they had at the time the VM issued
+ the UV_ESM ultracall. Further ``SRR0`` is expected to contain the
+ address of the instruction after the ``UV_ESM`` ultracall and ``SRR1``
+ the MSR value with which to return to the VM.
+
+ This hypercall will cleanup any partial state that was established for
+ the VM since the prior ``H_SVM_INIT_START`` hypercall, including paging
+ out pages that were paged-into secure memory, and issue the
+ ``UV_SVM_TERMINATE`` ultracall to terminate the VM.
+
+ After the partial state is cleaned up, control returns to the VM
+ (**not Ultravisor**), at the address specified in ``SRR0`` with the
+ MSR values set to the value in ``SRR1``.
+
+Use cases
+~~~~~~~~~
+
+ If after a successful call to ``H_SVM_INIT_START``, the Ultravisor
+ encounters an error while securing a virtual machine, either due
+ to lack of resources or because the VM's security information could
+ not be validated, Ultravisor informs the Hypervisor about it.
+ Hypervisor should use this call to clean up any internal state for
+ this virtual machine and return to the VM.

+=================
+Boot-time tracing
+=================
+
+:Author: Masami Hiramatsu <mhiramat@kernel.org>
+
+Overview
+========
+
+Boot-time tracing allows users to trace boot-time process including
+device initialization with full features of ftrace including per-event
+filter and actions, histograms, kprobe-events and synthetic-events,
+and trace instances.
+Since kernel command line is not enough to control these complex features,
+this uses bootconfig file to describe tracing feature programming.
+
+Options in the Boot Config
+==========================
+
+Here is the list of available options list for boot time tracing in
+boot config file [1]_. All options are under "ftrace." or "kernel."
+prefix. See kernel parameters for the options which starts
+with "kernel." prefix [2]_.
+
+.. [1] See :ref:`Documentation/admin-guide/bootconfig.rst <bootconfig>`
+.. [2] See :ref:`Documentation/admin-guide/kernel-parameters.rst <kernelparameters>`
+
+Ftrace Global Options
+---------------------
+
+Ftrace global options have "kernel." prefix in boot config, which means
+these options are passed as a part of kernel legacy command line.
+
+kernel.tp_printk
+ Output trace-event data on printk buffer too.
+
+kernel.dump_on_oops [= MODE]
+ Dump ftrace on Oops. If MODE = 1 or omitted, dump trace buffer
+ on all CPUs. If MODE = 2, dump a buffer on a CPU which kicks Oops.
+
+kernel.traceoff_on_warning
+ Stop tracing if WARN_ON() occurs.
+
+kernel.fgraph_max_depth = MAX_DEPTH
+ Set MAX_DEPTH to maximum depth of fgraph tracer.
+
+kernel.fgraph_filters = FILTER[, FILTER2...]
+ Add fgraph tracing function filters.
+
+kernel.fgraph_notraces = FILTER[, FILTER2...]
+ Add fgraph non-tracing function filters.
+
+
+Ftrace Per-instance Options
+---------------------------
+
+These options can be used for each instance including global ftrace node.
+
+ftrace.[instance.INSTANCE.]options = OPT1[, OPT2[...]]
+ Enable given ftrace options.
+
+ftrace.[instance.INSTANCE.]trace_clock = CLOCK
+ Set given CLOCK to ftrace's trace_clock.
+
+ftrace.[instance.INSTANCE.]buffer_size = SIZE
+ Configure ftrace buffer size to SIZE. You can use "KB" or "MB"
+ for that SIZE.
+
+ftrace.[instance.INSTANCE.]alloc_snapshot
+ Allocate snapshot buffer.
+
+ftrace.[instance.INSTANCE.]cpumask = CPUMASK
+ Set CPUMASK as trace cpu-mask.
+
+ftrace.[instance.INSTANCE.]events = EVENT[, EVENT2[...]]
+ Enable given events on boot. You can use a wild card in EVENT.
+
+ftrace.[instance.INSTANCE.]tracer = TRACER
+ Set TRACER to current tracer on boot. (e.g. function)
+
+ftrace.[instance.INSTANCE.]ftrace.filters
+ This will take an array of tracing function filter rules.
+
+ftrace.[instance.INSTANCE.]ftrace.notraces
+ This will take an array of NON-tracing function filter rules.
+
+
+Ftrace Per-Event Options
+------------------------
+
+These options are setting per-event options.
+
+ftrace.[instance.INSTANCE.]event.GROUP.EVENT.enable
+ Enable GROUP:EVENT tracing.
+
+ftrace.[instance.INSTANCE.]event.GROUP.EVENT.filter = FILTER
+ Set FILTER rule to the GROUP:EVENT.
+
+ftrace.[instance.INSTANCE.]event.GROUP.EVENT.actions = ACTION[, ACTION2[...]]
+ Set ACTIONs to the GROUP:EVENT.
+
+ftrace.[instance.INSTANCE.]event.kprobes.EVENT.probes = PROBE[, PROBE2[...]]
+ Defines new kprobe event based on PROBEs. It is able to define
+ multiple probes on one event, but those must have same type of
+ arguments. This option is available only for the event which
+ group name is "kprobes".
+
+ftrace.[instance.INSTANCE.]event.synthetic.EVENT.fields = FIELD[, FIELD2[...]]
+ Defines new synthetic event with FIELDs. Each field should be
+ "type varname".
+
+Note that kprobe and synthetic event definitions can be written under
+instance node, but those are also visible from other instances. So please
+take care for event name conflict.
+
+
+Examples
+========
+
+For example, to add filter and actions for each event, define kprobe
+events, and synthetic events with histogram, write a boot config like
+below::
+
+ ftrace.event {
+ task.task_newtask {
+ filter = "pid < 128"
+ enable
+ }
+ kprobes.vfs_read {
+ probes = "vfs_read $arg1 $arg2"
+ filter = "common_pid < 200"
+ enable
+ }
+ synthetic.initcall_latency {
+ fields = "unsigned long func", "u64 lat"
+ actions = "hist:keys=func.sym,lat:vals=lat:sort=lat"
+ }
+ initcall.initcall_start {
+ actions = "hist:keys=func:ts0=common_timestamp.usecs"
+ }
+ initcall.initcall_finish {
+ actions = "hist:keys=func:lat=common_timestamp.usecs-$ts0:onmatch(initcall.initcall_start).initcall_latency(func,$lat)"
+ }
+ }
+
+Also, boot-time tracing supports "instance" node, which allows us to run
+several tracers for different purpose at once. For example, one tracer
+is for tracing functions starting with "user\_", and others tracing
+"kernel\_" functions, you can write boot config as below::
+
+ ftrace.instance {
+ foo {
+ tracer = "function"
+ ftrace.filters = "user_*"
+ }
+ bar {
+ tracer = "function"
+ ftrace.filters = "kernel_*"
+ }
+ }
+
+The instance node also accepts event nodes so that each instance
+can customize its event tracing.
+
+This boot-time tracing also supports ftrace kernel parameters via boot
+config.
+For example, following kernel parameters::
+
+ trace_options=sym-addr trace_event=initcall:* tp_printk trace_buf_size=1M ftrace=function ftrace_filter="vfs*"
+
+This can be written in boot config like below::
+
+ kernel {
+ trace_options = sym-addr
+ trace_event = "initcall:*"
+ tp_printk
+ trace_buf_size = 1M
+ ftrace = function
+ ftrace_filter = "vfs*"
+ }
+
+Note that parameters start with "kernel" prefix instead of "ftrace".

+6.3 In-kernel trace event API
+-----------------------------
+
+In most cases, the command-line interface to trace events is more than
+sufficient. Sometimes, however, applications might find the need for
+more complex relationships than can be expressed through a simple
+series of linked command-line expressions, or putting together sets of
+commands may be simply too cumbersome. An example might be an
+application that needs to 'listen' to the trace stream in order to
+maintain an in-kernel state machine detecting, for instance, when an
+illegal kernel state occurs in the scheduler.
+
+The trace event subsystem provides an in-kernel API allowing modules
+or other kernel code to generate user-defined 'synthetic' events at
+will, which can be used to either augment the existing trace stream
+and/or signal that a particular important state has occurred.
+
+A similar in-kernel API is also available for creating kprobe and
+kretprobe events.
+
+Both the synthetic event and k/ret/probe event APIs are built on top
+of a lower-level "dynevent_cmd" event command API, which is also
+available for more specialized applications, or as the basis of other
+higher-level trace event APIs.
+
+The API provided for these purposes is describe below and allows the
+following:
+
+ - dynamically creating synthetic event definitions
+ - dynamically creating kprobe and kretprobe event definitions
+ - tracing synthetic events from in-kernel code
+ - the low-level "dynevent_cmd" API
+
+6.3.1 Dyamically creating synthetic event definitions
+-----------------------------------------------------
+
+There are a couple ways to create a new synthetic event from a kernel
+module or other kernel code.
+
+The first creates the event in one step, using synth_event_create().
+In this method, the name of the event to create and an array defining
+the fields is supplied to synth_event_create(). If successful, a
+synthetic event with that name and fields will exist following that
+call. For example, to create a new "schedtest" synthetic event:
+
+ ret = synth_event_create("schedtest", sched_fields,
+ ARRAY_SIZE(sched_fields), THIS_MODULE);
+
+The sched_fields param in this example points to an array of struct
+synth_field_desc, each of which describes an event field by type and
+name:
+
+ static struct synth_field_desc sched_fields[] = {
+ { .type = "pid_t", .name = "next_pid_field" },
+ { .type = "char[16]", .name = "next_comm_field" },
+ { .type = "u64", .name = "ts_ns" },
+ { .type = "u64", .name = "ts_ms" },
+ { .type = "unsigned int", .name = "cpu" },
+ { .type = "char[64]", .name = "my_string_field" },
+ { .type = "int", .name = "my_int_field" },
+ };
+
+See synth_field_size() for available types. If field_name contains [n]
+the field is considered to be an array.
+
+If the event is created from within a module, a pointer to the module
+must be passed to synth_event_create(). This will ensure that the
+trace buffer won't contain unreadable events when the module is
+removed.
+
+At this point, the event object is ready to be used for generating new
+events.
+
+In the second method, the event is created in several steps. This
+allows events to be created dynamically and without the need to create
+and populate an array of fields beforehand.
+
+To use this method, an empty or partially empty synthetic event should
+first be created using synth_event_gen_cmd_start() or
+synth_event_gen_cmd_array_start(). For synth_event_gen_cmd_start(),
+the name of the event along with one or more pairs of args each pair
+representing a 'type field_name;' field specification should be
+supplied. For synth_event_gen_cmd_array_start(), the name of the
+event along with an array of struct synth_field_desc should be
+supplied. Before calling synth_event_gen_cmd_start() or
+synth_event_gen_cmd_array_start(), the user should create and
+initialize a dynevent_cmd object using synth_event_cmd_init().
+
+For example, to create a new "schedtest" synthetic event with two
+fields:
+
+ struct dynevent_cmd cmd;
+ char *buf;
+
+ /* Create a buffer to hold the generated command */
+ buf = kzalloc(MAX_DYNEVENT_CMD_LEN, GFP_KERNEL);
+
+ /* Before generating the command, initialize the cmd object */
+ synth_event_cmd_init(&cmd, buf, MAX_DYNEVENT_CMD_LEN);
+
+ ret = synth_event_gen_cmd_start(&cmd, "schedtest", THIS_MODULE,
+ "pid_t", "next_pid_field",
+ "u64", "ts_ns");
+
+Alternatively, using an array of struct synth_field_desc fields
+containing the same information:
+
+ ret = synth_event_gen_cmd_array_start(&cmd, "schedtest", THIS_MODULE,
+ fields, n_fields);
+
+Once the synthetic event object has been created, it can then be
+populated with more fields. Fields are added one by one using
+synth_event_add_field(), supplying the dynevent_cmd object, a field
+type, and a field name. For example, to add a new int field named
+"intfield", the following call should be made:
+
+ ret = synth_event_add_field(&cmd, "int", "intfield");
+
+See synth_field_size() for available types. If field_name contains [n]
+the field is considered to be an array.
+
+A group of fields can also be added all at once using an array of
+synth_field_desc with add_synth_fields(). For example, this would add
+just the first four sched_fields:
+
+ ret = synth_event_add_fields(&cmd, sched_fields, 4);
+
+If you already have a string of the form 'type field_name',
+synth_event_add_field_str() can be used to add it as-is; it will
+also automatically append a ';' to the string.
+
+Once all the fields have been added, the event should be finalized and
+registered by calling the synth_event_gen_cmd_end() function:
+
+ ret = synth_event_gen_cmd_end(&cmd);
+
+At this point, the event object is ready to be used for tracing new
+events.
+
+6.3.3 Tracing synthetic events from in-kernel code
+--------------------------------------------------
+
+To trace a synthetic event, there are several options. The first
+option is to trace the event in one call, using synth_event_trace()
+with a variable number of values, or synth_event_trace_array() with an
+array of values to be set. A second option can be used to avoid the
+need for a pre-formed array of values or list of arguments, via
+synth_event_trace_start() and synth_event_trace_end() along with
+synth_event_add_next_val() or synth_event_add_val() to add the values
+piecewise.
+
+6.3.3.1 Tracing a synthetic event all at once
+---------------------------------------------
+
+To trace a synthetic event all at once, the synth_event_trace() or
+synth_event_trace_array() functions can be used.
+
+The synth_event_trace() function is passed the trace_event_file
+representing the synthetic event (which can be retrieved using
+trace_get_event_file() using the synthetic event name, "synthetic" as
+the system name, and the trace instance name (NULL if using the global
+trace array)), along with an variable number of u64 args, one for each
+synthetic event field, and the number of values being passed.
+
+So, to trace an event corresponding to the synthetic event definition
+above, code like the following could be used:
+
+ ret = synth_event_trace(create_synth_test, 7, /* number of values */
+ 444, /* next_pid_field */
+ (u64)"clackers", /* next_comm_field */
+ 1000000, /* ts_ns */
+ 1000, /* ts_ms */
+ smp_processor_id(),/* cpu */
+ (u64)"Thneed", /* my_string_field */
+ 999); /* my_int_field */
+
+All vals should be cast to u64, and string vals are just pointers to
+strings, cast to u64. Strings will be copied into space reserved in
+the event for the string, using these pointers.
+
+Alternatively, the synth_event_trace_array() function can be used to
+accomplish the same thing. It is passed the trace_event_file
+representing the synthetic event (which can be retrieved using
+trace_get_event_file() using the synthetic event name, "synthetic" as
+the system name, and the trace instance name (NULL if using the global
+trace array)), along with an array of u64, one for each synthetic
+event field.
+
+To trace an event corresponding to the synthetic event definition
+above, code like the following could be used:
+
+ u64 vals[7];
+
+ vals[0] = 777; /* next_pid_field */
+ vals[1] = (u64)"tiddlywinks"; /* next_comm_field */
+ vals[2] = 1000000; /* ts_ns */
+ vals[3] = 1000; /* ts_ms */
+ vals[4] = smp_processor_id(); /* cpu */
+ vals[5] = (u64)"thneed"; /* my_string_field */
+ vals[6] = 398; /* my_int_field */
+
+The 'vals' array is just an array of u64, the number of which must
+match the number of field in the synthetic event, and which must be in
+the same order as the synthetic event fields.
+
+All vals should be cast to u64, and string vals are just pointers to
+strings, cast to u64. Strings will be copied into space reserved in
+the event for the string, using these pointers.
+
+In order to trace a synthetic event, a pointer to the trace event file
+is needed. The trace_get_event_file() function can be used to get
+it - it will find the file in the given trace instance (in this case
+NULL since the top trace array is being used) while at the same time
+preventing the instance containing it from going away:
+
+ schedtest_event_file = trace_get_event_file(NULL, "synthetic",
+ "schedtest");
+
+Before tracing the event, it should be enabled in some way, otherwise
+the synthetic event won't actually show up in the trace buffer.
+
+To enable a synthetic event from the kernel, trace_array_set_clr_event()
+can be used (which is not specific to synthetic events, so does need
+the "synthetic" system name to be specified explicitly).
+
+To enable the event, pass 'true' to it:
+
+ trace_array_set_clr_event(schedtest_event_file->tr,
+ "synthetic", "schedtest", true);
+
+To disable it pass false:
+
+ trace_array_set_clr_event(schedtest_event_file->tr,
+ "synthetic", "schedtest", false);
+
+Finally, synth_event_trace_array() can be used to actually trace the
+event, which should be visible in the trace buffer afterwards:
+
+ ret = synth_event_trace_array(schedtest_event_file, vals,
+ ARRAY_SIZE(vals));
+
+To remove the synthetic event, the event should be disabled, and the
+trace instance should be 'put' back using trace_put_event_file():
+
+ trace_array_set_clr_event(schedtest_event_file->tr,
+ "synthetic", "schedtest", false);
+ trace_put_event_file(schedtest_event_file);
+
+If those have been successful, synth_event_delete() can be called to
+remove the event:
+
+ ret = synth_event_delete("schedtest");
+
+6.3.3.1 Tracing a synthetic event piecewise
+-------------------------------------------
+
+To trace a synthetic using the piecewise method described above, the
+synth_event_trace_start() function is used to 'open' the synthetic
+event trace:
+
+ struct synth_trace_state trace_state;
+
+ ret = synth_event_trace_start(schedtest_event_file, &trace_state);
+
+It's passed the trace_event_file representing the synthetic event
+using the same methods as described above, along with a pointer to a
+struct synth_trace_state object, which will be zeroed before use and
+used to maintain state between this and following calls.
+
+Once the event has been opened, which means space for it has been
+reserved in the trace buffer, the individual fields can be set. There
+are two ways to do that, either one after another for each field in
+the event, which requires no lookups, or by name, which does. The
+tradeoff is flexibility in doing the assignments vs the cost of a
+lookup per field.
+
+To assign the values one after the other without lookups,
+synth_event_add_next_val() should be used. Each call is passed the
+same synth_trace_state object used in the synth_event_trace_start(),
+along with the value to set the next field in the event. After each
+field is set, the 'cursor' points to the next field, which will be set
+by the subsequent call, continuing until all the fields have been set
+in order. The same sequence of calls as in the above examples using
+this method would be (without error-handling code):
+
+ /* next_pid_field */
+ ret = synth_event_add_next_val(777, &trace_state);
+
+ /* next_comm_field */
+ ret = synth_event_add_next_val((u64)"slinky", &trace_state);
+
+ /* ts_ns */
+ ret = synth_event_add_next_val(1000000, &trace_state);
+
+ /* ts_ms */
+ ret = synth_event_add_next_val(1000, &trace_state);
+
+ /* cpu */
+ ret = synth_event_add_next_val(smp_processor_id(), &trace_state);
+
+ /* my_string_field */
+ ret = synth_event_add_next_val((u64)"thneed_2.01", &trace_state);
+
+ /* my_int_field */
+ ret = synth_event_add_next_val(395, &trace_state);
+
+To assign the values in any order, synth_event_add_val() should be
+used. Each call is passed the same synth_trace_state object used in
+the synth_event_trace_start(), along with the field name of the field
+to set and the value to set it to. The same sequence of calls as in
+the above examples using this method would be (without error-handling
+code):
+
+ ret = synth_event_add_val("next_pid_field", 777, &trace_state);
+ ret = synth_event_add_val("next_comm_field", (u64)"silly putty",
+ &trace_state);
+ ret = synth_event_add_val("ts_ns", 1000000, &trace_state);
+ ret = synth_event_add_val("ts_ms", 1000, &trace_state);
+ ret = synth_event_add_val("cpu", smp_processor_id(), &trace_state);
+ ret = synth_event_add_val("my_string_field", (u64)"thneed_9",
+ &trace_state);
+ ret = synth_event_add_val("my_int_field", 3999, &trace_state);
+
+Note that synth_event_add_next_val() and synth_event_add_val() are
+incompatible if used within the same trace of an event - either one
+can be used but not both at the same time.
+
+Finally, the event won't be actually traced until it's 'closed',
+which is done using synth_event_trace_end(), which takes only the
+struct synth_trace_state object used in the previous calls:
+
+ ret = synth_event_trace_end(&trace_state);
+
+Note that synth_event_trace_end() must be called at the end regardless
+of whether any of the add calls failed (say due to a bad field name
+being passed in).
+
+6.3.4 Dyamically creating kprobe and kretprobe event definitions
+----------------------------------------------------------------
+
+To create a kprobe or kretprobe trace event from kernel code, the
+kprobe_event_gen_cmd_start() or kretprobe_event_gen_cmd_start()
+functions can be used.
+
+To create a kprobe event, an empty or partially empty kprobe event
+should first be created using kprobe_event_gen_cmd_start(). The name
+of the event and the probe location should be specfied along with one
+or args each representing a probe field should be supplied to this
+function. Before calling kprobe_event_gen_cmd_start(), the user
+should create and initialize a dynevent_cmd object using
+kprobe_event_cmd_init().
+
+For example, to create a new "schedtest" kprobe event with two fields:
+
+ struct dynevent_cmd cmd;
+ char *buf;
+
+ /* Create a buffer to hold the generated command */
+ buf = kzalloc(MAX_DYNEVENT_CMD_LEN, GFP_KERNEL);
+
+ /* Before generating the command, initialize the cmd object */
+ kprobe_event_cmd_init(&cmd, buf, MAX_DYNEVENT_CMD_LEN);
+
+ /*
+ * Define the gen_kprobe_test event with the first 2 kprobe
+ * fields.
+ */
+ ret = kprobe_event_gen_cmd_start(&cmd, "gen_kprobe_test", "do_sys_open",
+ "dfd=%ax", "filename=%dx");
+
+Once the kprobe event object has been created, it can then be
+populated with more fields. Fields can be added using
+kprobe_event_add_fields(), supplying the dynevent_cmd object along
+with a variable arg list of probe fields. For example, to add a
+couple additional fields, the following call could be made:
+
+ ret = kprobe_event_add_fields(&cmd, "flags=%cx", "mode=+4($stack)");
+
+Once all the fields have been added, the event should be finalized and
+registered by calling the kprobe_event_gen_cmd_end() or
+kretprobe_event_gen_cmd_end() functions, depending on whether a kprobe
+or kretprobe command was started:
+
+ ret = kprobe_event_gen_cmd_end(&cmd);
+
+or
+
+ ret = kretprobe_event_gen_cmd_end(&cmd);
+
+At this point, the event object is ready to be used for tracing new
+events.
+
+Similarly, a kretprobe event can be created using
+kretprobe_event_gen_cmd_start() with a probe name and location and
+additional params such as $retval:
+
+ ret = kretprobe_event_gen_cmd_start(&cmd, "gen_kretprobe_test",
+ "do_sys_open", "$retval");
+
+Similar to the synthetic event case, code like the following can be
+used to enable the newly created kprobe event:
+
+ gen_kprobe_test = trace_get_event_file(NULL, "kprobes", "gen_kprobe_test");
+
+ ret = trace_array_set_clr_event(gen_kprobe_test->tr,
+ "kprobes", "gen_kprobe_test", true);
+
+Finally, also similar to synthetic events, the following code can be
+used to give the kprobe event file back and delete the event:
+
+ trace_put_event_file(gen_kprobe_test);
+
+ ret = kprobe_event_delete("gen_kprobe_test");
+
+6.3.4 The "dynevent_cmd" low-level API
+--------------------------------------
+
+Both the in-kernel synthetic event and kprobe interfaces are built on
+top of a lower-level "dynevent_cmd" interface. This interface is
+meant to provide the basis for higher-level interfaces such as the
+synthetic and kprobe interfaces, which can be used as examples.
+
+The basic idea is simple and amounts to providing a general-purpose
+layer that can be used to generate trace event commands. The
+generated command strings can then be passed to the command-parsing
+and event creation code that already exists in the trace event
+subystem for creating the corresponding trace events.
+
+In a nutshell, the way it works is that the higher-level interface
+code creates a struct dynevent_cmd object, then uses a couple
+functions, dynevent_arg_add() and dynevent_arg_pair_add() to build up
+a command string, which finally causes the command to be executed
+using the dynevent_create() function. The details of the interface
+are described below.
+
+The first step in building a new command string is to create and
+initialize an instance of a dynevent_cmd. Here, for instance, we
+create a dynevent_cmd on the stack and initialize it:
+
+ struct dynevent_cmd cmd;
+ char *buf;
+ int ret;
+
+ buf = kzalloc(MAX_DYNEVENT_CMD_LEN, GFP_KERNEL);
+
+ dynevent_cmd_init(cmd, buf, maxlen, DYNEVENT_TYPE_FOO,
+ foo_event_run_command);
+
+The dynevent_cmd initialization needs to be given a user-specified
+buffer and the length of the buffer (MAX_DYNEVENT_CMD_LEN can be used
+for this purpose - at 2k it's generally too big to be comfortably put
+on the stack, so is dynamically allocated), a dynevent type id, which
+is meant to be used to check that further API calls are for the
+correct command type, and a pointer to an event-specific run_command()
+callback that will be called to actually execute the event-specific
+command function.
+
+Once that's done, the command string can by built up by successive
+calls to argument-adding functions.
+
+To add a single argument, define and initialize a struct dynevent_arg
+or struct dynevent_arg_pair object. Here's an example of the simplest
+possible arg addition, which is simply to append the given string as
+a whitespace-separated argument to the command:
+
+ struct dynevent_arg arg;
+
+ dynevent_arg_init(&arg, NULL, 0);
+
+ arg.str = name;
+
+ ret = dynevent_arg_add(cmd, &arg);
+
+The arg object is first initialized using dynevent_arg_init() and in
+this case the parameters are NULL or 0, which means there's no
+optional sanity-checking function or separator appended to the end of
+the arg.
+
+Here's another more complicated example using an 'arg pair', which is
+used to create an argument that consists of a couple components added
+together as a unit, for example, a 'type field_name;' arg or a simple
+expression arg e.g. 'flags=%cx':
+
+ struct dynevent_arg_pair arg_pair;
+
+ dynevent_arg_pair_init(&arg_pair, dynevent_foo_check_arg_fn, 0, ';');
+
+ arg_pair.lhs = type;
+ arg_pair.rhs = name;
+
+ ret = dynevent_arg_pair_add(cmd, &arg_pair);
+
+Again, the arg_pair is first initialized, in this case with a callback
+function used to check the sanity of the args (for example, that
+neither part of the pair is NULL), along with a character to be used
+to add an operator between the pair (here none) and a separator to be
+appended onto the end of the arg pair (here ';').
+
+There's also a dynevent_str_add() function that can be used to simply
+add a string as-is, with no spaces, delimeters, or arg check.
+
+Any number of dynevent_*_add() calls can be made to build up the string
+(until its length surpasses cmd->maxlen). When all the arguments have
+been added and the command string is complete, the only thing left to
+do is run the command, which happens by simply calling
+dynevent_create():
+
+ ret = dynevent_create(&cmd);
+
+At that point, if the return value is 0, the dynamic event has been
+created and is ready to use.
+
+See the dynevent_cmd function definitions themselves for the details
+of the API.

+情况，硬件安全小组将立即通知相关方。如果您或任何人发现潜在的违规行为，请立即
+向硬件安全人员报告。
+
+流程
+^^^^
+
+由于Linux内核开发的全球分布式特性，面对面的会议几乎不可能解决硬件安全问题。
+由于时区和其他因素，电话会议很难协调，只能在绝对必要时使用。加密电子邮件已被
+证明是解决此类问题的最有效和最安全的通信方法。
+
+开始披露
+""""""""
+
+披露内容首先通过电子邮件联系Linux内核硬件安全小组。此初始联系人应包含问题的
+描述和任何已知受影响硬件的列表。如果您的组织制造或分发受影响的硬件，我们建议
+您也考虑哪些其他硬件可能会受到影响。
+
+硬件安全小组将提供一个特定于事件的加密邮件列表，用于与报告者进行初步讨论、
+进一步披露和协调。
+
+硬件安全小组将向披露方提供一份开发人员（领域专家）名单，在与开发人员确认他们
+将遵守本谅解备忘录和文件化流程后，应首先告知开发人员有关该问题的信息。这些开发
+人员组成初始响应小组，并在初始接触后负责处理问题。硬件安全小组支持响应小组，
+但不一定参与缓解开发过程。
+
+虽然个别开发人员可能通过其雇主受到保密协议的保护，但他们不能以Linux内核开发
+人员的身份签订个别保密协议。但是，他们将同意遵守这一书面程序和谅解备忘录。
+
+披露方应提供已经或应该被告知该问题的所有其他实体的联系人名单。这有几个目的:
+
+ - 披露的实体列表允许跨行业通信，例如其他操作系统供应商、硬件供应商等。
+
+ - 可联系已披露的实体，指定应参与缓解措施开发的专家。
+
+ - 如果需要处理某一问题的专家受雇于某一上市实体或某一上市实体的成员，则响应
+ 小组可要求该实体披露该专家。这确保专家也是实体反应小组的一部分。
+
+披露
+""""
+
+披露方通过特定的加密邮件列表向初始响应小组提供详细信息。
+
+根据我们的经验，这些问题的技术文档通常是一个足够的起点，最好通过电子邮件进行
+进一步的技术澄清。
+
+缓解开发
+""""""""
+
+初始响应小组设置加密邮件列表，或在适当的情况下重新修改现有邮件列表。
+
+使用邮件列表接近于正常的Linux开发过程，并且在过去已经成功地用于为各种硬件安全
+问题开发缓解措施。
+
+邮件列表的操作方式与正常的Linux开发相同。发布、讨论和审查修补程序，如果同意，
+则应用于非公共git存储库，参与开发人员只能通过安全连接访问该存储库。存储库包含
+针对主线内核的主开发分支，并根据需要为稳定的内核版本提供向后移植分支。
+
+最初的响应小组将根据需要从Linux内核开发人员社区中确定更多的专家。引进专家可以
+在开发过程中的任何时候发生，需要及时处理。
+
+如果专家受雇于披露方提供的披露清单上的实体或其成员，则相关实体将要求其参与。
+
+否则，披露方将被告知专家参与的情况。谅解备忘录涵盖了专家，要求披露方确认参与。
+如果披露方有令人信服的理由提出异议，则必须在五个工作日内提出异议，并立即与事件
+小组解决。如果披露方在五个工作日内未作出回应，则视为默许。
+
+在确认或解决异议后，专家由事件小组披露，并进入开发过程。
+
+协调发布
+""""""""
+
+有关各方将协商限制结束的日期和时间。此时，准备好的缓解措施集成到相关的内核树中
+并发布。
+
+虽然我们理解硬件安全问题需要协调限制时间，但限制时间应限制在所有有关各方制定、
+测试和准备缓解措施所需的最短时间内。人为地延长限制时间以满足会议讨论日期或其他
+非技术原因，会给相关的开发人员和响应小组带来了更多的工作和负担，因为补丁需要
+保持最新，以便跟踪正在进行的上游内核开发，这可能会造成冲突的更改。
+
+CVE分配
+"""""""
+
+硬件安全小组和初始响应小组都不分配CVE，开发过程也不需要CVE。如果CVE是由披露方
+提供的，则可用于文档中。
+
+流程专使
+--------
+
+为了协助这一进程，我们在各组织设立了专使，他们可以回答有关报告流程和进一步处理
+的问题或提供指导。专使不参与特定问题的披露，除非响应小组或相关披露方提出要求。
+现任专使名单:
+

+ AMD Tom Lendacky <tom.lendacky@amd.com>
+ IBM
+ Intel Tony Luck <tony.luck@intel.com>
+ Qualcomm Trilok Soni <tsoni@codeaurora.org>

+
+加密邮件列表
+------------
+
+我们使用加密邮件列表进行通信。这些列表的工作原理是，发送到列表的电子邮件使用
+列表的PGP密钥或列表的/MIME证书进行加密。邮件列表软件对电子邮件进行解密，并
+使用订阅者的PGP密钥或S/MIME证书为每个订阅者分别对其进行重新加密。有关邮件列表
+软件和用于确保列表安全和数据保护的设置的详细信息，请访问:
+https://www.kernel.org/....
+
+关键点
+^^^^^^
+
+初次接触见 :ref:`zh_Contact`. 对于特定于事件的邮件列表，密钥和S/MIME证书通过
+特定列表发送的电子邮件传递给订阅者。
+
+订阅事件特定列表
+^^^^^^^^^^^^^^^^
+
+订阅由响应小组处理。希望参与通信的披露方将潜在订户的列表发送给响应组，以便
+响应组可以验证订阅请求。
+
+每个订户都需要通过电子邮件向响应小组发送订阅请求。电子邮件必须使用订阅服务器
+的PGP密钥或S/MIME证书签名。如果使用PGP密钥，则必须从公钥服务器获得该密钥，
+并且理想情况下该密钥连接到Linux内核的PGP信任网。另请参见:
+https://www.kernel.org/signature.html.
+
+响应小组验证订阅者，并将订阅者添加到列表中。订阅后，订阅者将收到来自邮件列表
+的电子邮件，该邮件列表使用列表的PGP密钥或列表的/MIME证书签名。订阅者的电子邮件
+客户端可以从签名中提取PGP密钥或S/MIME证书，以便订阅者可以向列表发送加密电子
+邮件。

+内核驱动声明
+------------
+
+关于Linux内核模块的立场声明
+===========================
+
+我们，以下署名的Linux内核开发人员，认为任何封闭源Linux内核模块或驱动程序都是
+有害的和不可取的。我们已经一再发现它们对Linux用户，企业和更大的Linux生态系统
+有害。这样的模块否定了Linux开发模型的开放性，稳定性，灵活性和可维护性，并使
+他们的用户无法使用Linux社区的专业知识。提供闭源内核模块的供应商迫使其客户
+放弃Linux的主要优势或选择新的供应商。因此，为了充分利用开源所提供的成本节省和
+共享支持优势，我们敦促供应商采取措施，以开源内核代码在Linux上为其客户提供支持。
+
+我们只为自己说话，而不是我们今天可能会为之工作，过去或将来会为之工作的任何公司。

+个人强制执行行动的方式有利于我们的社区，不会对我们软件生态系统的健康和增长
+产生意外的负面影响。为了阻止无益的执法行动，我们同意代表我们自己和我们版权
+利益的任何继承人对Linux内核用户作出以下符合我们开发社区最大利益的承诺:
+
+ 尽管有GPL-2.0的终止条款，我们同意，采用以下GPL-3.0条款作为我们许可证下的
+ 附加许可，作为任何对许可证下权利的非防御性主张，这符合我们开发社区的最佳
+ 利益。
+
+ 但是，如果您停止所有违反本许可证的行为，则您从特定版权持有人处获得的
+ 许可证将被恢复：（a）暂时恢复，除非版权持有人明确并最终终止您的许可证；
+ 以及（b）永久恢复, 如果版权持有人未能在你终止违反后60天内以合理方式
+ 通知您违反本许可证的行为，则永久恢复您的许可证。
+
+ 此外，如果版权所有者以某种合理的方式通知您违反了本许可，这是您第一次
+ 从该版权所有者处收到违反本许可的通知（对于任何作品），并且您在收到通知
+ 后的30天内纠正违规行为。则您从特定版权所有者处获得的许可将永久恢复.
+
+我们提供这些保证的目的是鼓励更多地使用该软件。我们希望公司和个人使用、修改和
+分发此软件。我们希望以公开和透明的方式与用户合作，以消除我们对法规遵从性或强制
+执行的任何不确定性，这些不确定性可能会限制我们软件的采用。我们将法律行动视为
+最后手段，只有在其他社区努力未能解决这一问题时才采取行动。
+
+最后，一旦一个不合规问题得到解决，我们希望用户会感到欢迎，加入我们为之努力的
+这个项目。共同努力，我们会更强大。
+
+除了下面提到的以外，我们只为自己说话，而不是为今天、过去或将来可能为之工作的

-Intel(R) Memory Protection Extensions (MPX)
-===========================================
-
-Intel(R) MPX Overview
-=====================
-
-Intel(R) Memory Protection Extensions (Intel(R) MPX) is a new capability
-introduced into Intel Architecture. Intel MPX provides hardware features
-that can be used in conjunction with compiler changes to check memory
-references, for those references whose compile-time normal intentions are
-usurped at runtime due to buffer overflow or underflow.
-
-You can tell if your CPU supports MPX by looking in /proc/cpuinfo::
-
- cat /proc/cpuinfo | grep ' mpx '
-
-For more information, please refer to Intel(R) Architecture Instruction
-Set Extensions Programming Reference, Chapter 9: Intel(R) Memory Protection
-Extensions.
-
-Note: As of December 2014, no hardware with MPX is available but it is
-possible to use SDE (Intel(R) Software Development Emulator) instead, which
-can be downloaded from
-http://software.intel.com/en-us/articles/intel-software-development-emulator
-
-
-How to get the advantage of MPX
-===============================
-
-For MPX to work, changes are required in the kernel, binutils and compiler.
-No source changes are required for applications, just a recompile.
-
-There are a lot of moving parts of this to all work right. The following
-is how we expect the compiler, application and kernel to work together.
-
-1) Application developer compiles with -fmpx. The compiler will add the
- instrumentation as well as some setup code called early after the app
- starts. New instruction prefixes are noops for old CPUs.
-2) That setup code allocates (virtual) space for the "bounds directory",
- points the "bndcfgu" register to the directory (must also set the valid
- bit) and notifies the kernel (via the new prctl(PR_MPX_ENABLE_MANAGEMENT))
- that the app will be using MPX. The app must be careful not to access
- the bounds tables between the time when it populates "bndcfgu" and
- when it calls the prctl(). This might be hard to guarantee if the app
- is compiled with MPX. You can add "__attribute__((bnd_legacy))" to
- the function to disable MPX instrumentation to help guarantee this.
- Also be careful not to call out to any other code which might be
- MPX-instrumented.
-3) The kernel detects that the CPU has MPX, allows the new prctl() to
- succeed, and notes the location of the bounds directory. Userspace is
- expected to keep the bounds directory at that location. We note it
- instead of reading it each time because the 'xsave' operation needed
- to access the bounds directory register is an expensive operation.
-4) If the application needs to spill bounds out of the 4 registers, it
- issues a bndstx instruction. Since the bounds directory is empty at
- this point, a bounds fault (#BR) is raised, the kernel allocates a
- bounds table (in the user address space) and makes the relevant entry
- in the bounds directory point to the new table.
-5) If the application violates the bounds specified in the bounds registers,
- a separate kind of #BR is raised which will deliver a signal with
- information about the violation in the 'struct siginfo'.
-6) Whenever memory is freed, we know that it can no longer contain valid
- pointers, and we attempt to free the associated space in the bounds
- tables. If an entire table becomes unused, we will attempt to free
- the table and remove the entry in the directory.
-
-To summarize, there are essentially three things interacting here:
-
-GCC with -fmpx:
- * enables annotation of code with MPX instructions and prefixes
- * inserts code early in the application to call in to the "gcc runtime"
-GCC MPX Runtime:
- * Checks for hardware MPX support in cpuid leaf
- * allocates virtual space for the bounds directory (malloc() essentially)
- * points the hardware BNDCFGU register at the directory
- * calls a new prctl(PR_MPX_ENABLE_MANAGEMENT) to notify the kernel to
- start managing the bounds directories
-Kernel MPX Code:
- * Checks for hardware MPX support in cpuid leaf
- * Handles #BR exceptions and sends SIGSEGV to the app when it violates
- bounds, like during a buffer overflow.
- * When bounds are spilled in to an unallocated bounds table, the kernel
- notices in the #BR exception, allocates the virtual space, then
- updates the bounds directory to point to the new table. It keeps
- special track of the memory with a VM_MPX flag.
- * Frees unused bounds tables at the time that the memory they described
- is unmapped.
-
-
-How does MPX kernel code work
-=============================
-
-Handling #BR faults caused by MPX
----------------------------------
-
-When MPX is enabled, there are 2 new situations that can generate
-#BR faults.
-
- * new bounds tables (BT) need to be allocated to save bounds.
- * bounds violation caused by MPX instructions.
-
-We hook #BR handler to handle these two new situations.
-
-On-demand kernel allocation of bounds tables
---------------------------------------------
-
-MPX only has 4 hardware registers for storing bounds information. If
-MPX-enabled code needs more than these 4 registers, it needs to spill
-them somewhere. It has two special instructions for this which allow
-the bounds to be moved between the bounds registers and some new "bounds
-tables".
-
-#BR exceptions are a new class of exceptions just for MPX. They are
-similar conceptually to a page fault and will be raised by the MPX
-hardware during both bounds violations or when the tables are not
-present. The kernel handles those #BR exceptions for not-present tables
-by carving the space out of the normal processes address space and then
-pointing the bounds-directory over to it.
-
-The tables need to be accessed and controlled by userspace because
-the instructions for moving bounds in and out of them are extremely
-frequent. They potentially happen every time a register points to
-memory. Any direct kernel involvement (like a syscall) to access the
-tables would obviously destroy performance.
-
-Why not do this in userspace? MPX does not strictly require anything in
-the kernel. It can theoretically be done completely from userspace. Here
-are a few ways this could be done. We don't think any of them are practical
-in the real-world, but here they are.
-
-:Q: Can virtual space simply be reserved for the bounds tables so that we
- never have to allocate them?
-:A: MPX-enabled application will possibly create a lot of bounds tables in
- process address space to save bounds information. These tables can take
- up huge swaths of memory (as much as 80% of the memory on the system)
- even if we clean them up aggressively. In the worst-case scenario, the
- tables can be 4x the size of the data structure being tracked. IOW, a
- 1-page structure can require 4 bounds-table pages. An X-GB virtual
- area needs 4*X GB of virtual space, plus 2GB for the bounds directory.
- If we were to preallocate them for the 128TB of user virtual address
- space, we would need to reserve 512TB+2GB, which is larger than the
- entire virtual address space today. This means they can not be reserved
- ahead of time. Also, a single process's pre-populated bounds directory
- consumes 2GB of virtual *AND* physical memory. IOW, it's completely
- infeasible to prepopulate bounds directories.
-
-:Q: Can we preallocate bounds table space at the same time memory is
- allocated which might contain pointers that might eventually need
- bounds tables?
-:A: This would work if we could hook the site of each and every memory
- allocation syscall. This can be done for small, constrained applications.
- But, it isn't practical at a larger scale since a given app has no
- way of controlling how all the parts of the app might allocate memory
- (think libraries). The kernel is really the only place to intercept
- these calls.
-
-:Q: Could a bounds fault be handed to userspace and the tables allocated
- there in a signal handler instead of in the kernel?
-:A: mmap() is not on the list of safe async handler functions and even
- if mmap() would work it still requires locking or nasty tricks to
- keep track of the allocation state there.
-
-Having ruled out all of the userspace-only approaches for managing
-bounds tables that we could think of, we create them on demand in
-the kernel.
-
-Decoding MPX instructions
--------------------------
-
-If a #BR is generated due to a bounds violation caused by MPX.
-We need to decode MPX instructions to get violation address and
-set this address into extended struct siginfo.
-
-The _sigfault field of struct siginfo is extended as follow::
-
- 87 /* SIGILL, SIGFPE, SIGSEGV, SIGBUS */
- 88 struct {
- 89 void __user *_addr; /* faulting insn/memory ref. */
- 90 #ifdef __ARCH_SI_TRAPNO
- 91 int _trapno; /* TRAP # which caused the signal */
- 92 #endif
- 93 short _addr_lsb; /* LSB of the reported address */
- 94 struct {
- 95 void __user *_lower;
- 96 void __user *_upper;
- 97 } _addr_bnd;
- 98 } _sigfault;
-
-The '_addr' field refers to violation address, and new '_addr_and'
-field refers to the upper/lower bounds when a #BR is caused.
-
-Glibc will be also updated to support this new siginfo. So user
-can get violation address and bounds when bounds violations occur.
-
-Cleanup unused bounds tables
-----------------------------
-
-When a BNDSTX instruction attempts to save bounds to a bounds directory
-entry marked as invalid, a #BR is generated. This is an indication that
-no bounds table exists for this entry. In this case the fault handler
-will allocate a new bounds table on demand.
-
-Since the kernel allocated those tables on-demand without userspace
-knowledge, it is also responsible for freeing them when the associated
-mappings go away.
-
-Here, the solution for this issue is to hook do_munmap() to check
-whether one process is MPX enabled. If yes, those bounds tables covered
-in the virtual address region which is being unmapped will be freed also.
-
-Adding new prctl commands
--------------------------
-
-Two new prctl commands are added to enable and disable MPX bounds tables
-management in kernel.
-::
-
- 155 #define PR_MPX_ENABLE_MANAGEMENT 43
- 156 #define PR_MPX_DISABLE_MANAGEMENT 44
-
-Runtime library in userspace is responsible for allocation of bounds
-directory. So kernel have to use XSAVE instruction to get the base
-of bounds directory from BNDCFG register.
-
-But XSAVE is expected to be very expensive. In order to do performance
-optimization, we have to get the base of bounds directory and save it
-into struct mm_struct to be used in future during PR_MPX_ENABLE_MANAGEMENT
-command execution.
-
-
-Special rules
-=============
-
-1) If userspace is requesting help from the kernel to do the management
-of bounds tables, it may not create or modify entries in the bounds directory.
-
-Certainly users can allocate bounds tables and forcibly point the bounds
-directory at them through XSAVE instruction, and then set valid bit
-of bounds entry to have this entry valid. But, the kernel will decline
-to assist in managing these tables.
-
-2) Userspace may not take multiple bounds directory entries and point
-them at the same bounds table.
-
-This is allowed architecturally. See more information "Intel(R) Architecture
-Instruction Set Extensions Programming Reference" (9.3.4).
-
-However, if users did this, the kernel might be fooled in to unmapping an
-in-use bounds table since it does not recognize sharing.

- MPX provides hardware features that can be used in
- conjunction with compiler-instrumented code to check
- memory references. It is designed to detect buffer
- overflow or underflow bugs.
-
- This option enables running applications which are
- instrumented or otherwise use MPX. It does not use MPX
- itself inside the kernel or to protect the kernel
- against bad memory references.
-
- Enabling this option will make the kernel larger:
- ~8k of kernel text and 36 bytes of data on a 64-bit
- defconfig. It adds a long to the 'mm_struct' which
- will increase the kernel memory overhead of each
- process and adds some branches to paths used during
- exec() and munmap().
-
- For details, see Documentation/x86/intel_mpx.rst

- * To support dma_buf objects residing in highmem cpu access is page-based
- * using an api similar to kmap. Accessing a dma_buf is done in aligned chunks
- * of PAGE_SIZE size. Before accessing a chunk it needs to be mapped, which
- * returns a pointer in kernel virtual address space. Afterwards the chunk
- * needs to be unmapped again. There is no limit on how often a given chunk
- * can be mapped and unmapped, i.e. the importer does not need to call
- * begin_cpu_access again before mapping the same chunk again.
- *
- * Interfaces::
- * void \*dma_buf_kmap(struct dma_buf \*, unsigned long);
- * void dma_buf_kunmap(struct dma_buf \*, unsigned long, void \*);
- *
- * Implementing the functions is optional for exporters and for importers all
- * the restrictions of using kmap apply.
- *
- * dma_buf kmap calls outside of the range specified in begin_cpu_access are
- * undefined. If the range is not PAGE_SIZE aligned, kmap needs to succeed on
- * the partial chunks at the beginning and end but may return stale or bogus
- * data outside of the range (in these partial chunks).
- *
- * For some cases the overhead of kmap can be too high, a vmap interface
- * is introduced. This interface should be used very carefully, as vmalloc
- * space is a limited resources on many architectures.
+ * Since for most kernel internal dma-buf accesses need the entire buffer, a
+ * vmap interface is introduced. Note that on very old 32-bit architectures
+ * vmalloc space might be limited and result in vmap calls failing.

ideally have no use or idea of the global GPIO numberspace that has/was
used in the inception of the GPIO subsystem.
+The numberspace issue is the same as to why irq is moving away from irq
+numbers to IRQ descriptors.
+
+The underlying motivation for this is that the GPIO numberspace has become
+unmanageable: machine board files tend to become full of macros trying to
+establish the numberspace at compile-time, making it hard to add any numbers
+in the middle (such as if you missed a pin on a chip) without the numberspace
+breaking.
+
+Machine descriptions such as device tree or ACPI does not have a concept of the
+Linux GPIO number as those descriptions are external to the Linux kernel
+and treat GPIO lines as abstract entities.
+
+The runtime-assigned GPIO numberspace (what you get if you assign the GPIO
+base as -1 in struct gpio_chip) has also became unpredictable due to factors
+such as probe ordering and the introduction of -EPROBE_DEFER making probe
+ordering of independent GPIO chips essentially unpredictable, as their base
+number will be assigned on a first come first serve basis.
+
+The best way to get out of the problem is to make the global GPIO numbers
+unimportant by simply not using them. GPIO descriptors deal with this.

+/**
+ * DOC: DMUB interface and operation
+ *
+ * DMUB is the interface to the display DMCUB microcontroller on DCN hardware.
+ * It delegates hardware initialization and command submission to the
+ * microcontroller. DMUB is the shortname for DMCUB.
+ *
+ * This interface is not thread-safe. Ensure that all access to the interface
+ * is properly synchronized by the caller.
+ *
+ * Initialization and usage of the DMUB service should be done in the
+ * steps given below:
+ *
+ * 1. dmub_srv_create()
+ * 2. dmub_srv_has_hw_support()
+ * 3. dmub_srv_calc_region_info()
+ * 4. dmub_srv_hw_init()
+ *
+ * The call to dmub_srv_create() is required to use the server.
+ *
+ * The calls to dmub_srv_has_hw_support() and dmub_srv_calc_region_info()
+ * are helpers to query cache window size and allocate framebuffer(s)
+ * for the cache windows.
+ *
+ * The call to dmub_srv_hw_init() programs the DMCUB registers to prepare
+ * for command submission. Commands can be queued via dmub_srv_cmd_queue()
+ * and executed via dmub_srv_cmd_execute().
+ *
+ * If the queue is full the dmub_srv_wait_for_idle() call can be used to
+ * wait until the queue has been cleared.
+ *
+ * Destroying the DMUB service can be done by calling dmub_srv_destroy().
+ * This does not clear DMUB hardware state, only software state.
+ *
+ * The interface is intended to be standalone and should not depend on any
+ * other component within DAL.

+ *
+ * 1. Run drm_atomic_helper_prepare_planes(). Since this can fail and we

*
* 2. Synchronize with any outstanding nonblocking commit worker threads which

*
+ * IMPORTANT: A &drm_atomic_state update for multiple CRTCs is sequenced
+ * against all CRTCs therein. Therefore for atomic state updates which only flip
+ * planes the driver must not get the struct &drm_crtc_state of unrelated CRTCs
+ * in its atomic check code: This would prevent committing of atomic updates to

+ * requirements.

* 3. The software state is updated synchronously with
* drm_atomic_helper_swap_state(). Doing this under the protection of all modeset
- * locks means concurrent callers never see inconsistent state. And doing this
- * while it's guaranteed that no relevant nonblocking worker runs means that

+ * A set of bonded requests is intended to be run concurrently

+ * and a magic fence to schedule each of the bonded requests
+ * at the same time. A consequence of our current scheduler is that
+ * we only move requests to the HW ready queue when the request
+ * becomes ready, that is when all of its prerequisite fences have
+ * been signaled. As one of those fences is the master submit fence,
+ * there is a delay on all secondary fences as the HW may be
+ * currently busy. Equally, as all the requests are independent,
+ * they may have other fences that delay individual request
+ * submission to HW. Ergo, we do not guarantee that all requests are
+ * immediately submitted to HW at the same time, just that if the
+ * rules are abided by, they are ready at the same time as the
+ * first is submitted. Userspace can embed semaphores in its batch
+ * to ensure parallel execution of its phases as it requires.
+ * Though naturally it gets requested that perhaps the scheduler should
+ * take care of parallel execution, even across preemption events on
+ * different HW. (The proper answer is of course "lalalala".)
+ *
+ * With the submit-fence, we have identified three possible phases
+ * of synchronisation depending on the master fence: queued (not
+ * ready), executing, and signaled. The first two are quite simple
+ * and checked below. However, the signaled master fence handling is
+ * contentious. Currently we do not distinguish between a signaled
+ * fence and an expired fence, as once signaled it does not convey
+ * any information about the previous execution. It may even be freed
+ * and hence checking later it may not exist at all. Ergo we currently
+ * do not apply the bonding constraint for an already signaled fence,
+ * as our expectation is that it should not constrain the secondaries
+ * and is outside of the scope of the bonded request API (i.e. all
+ * userspace requests are meant to be running in parallel). As
+ * it imposes no constraint, and is effectively a no-op, we do not
+ * check below as normal execution flows are checked extensively above.
+ *
+ * XXX Is the degenerate handling of signaled submit fences the
+ * expected behaviour for userpace?

- * DOC: Global GTT views
- *
- * Background and previous state
- *
- * Historically objects could exists (be bound) in global GTT space only as
- * singular instances with a view representing all of the object's backing pages
- * in a linear fashion. This view will be called a normal view.
- *
- * To support multiple views of the same object, where the number of mapped
- * pages is not equal to the backing store, or where the layout of the pages
- * is not linear, concept of a GGTT view was added.
- *
- * One example of an alternative view is a stereo display driven by a single
- * image. In this case we would have a framebuffer looking like this
- * (2x2 pages):
- *
- * 12
- * 34
- *
- * Above would represent a normal GGTT view as normally mapped for GPU or CPU
- * rendering. In contrast, fed to the display engine would be an alternative
- * view which could look something like this:
- *
- * 1212
- * 3434
- *
- * In this example both the size and layout of pages in the alternative view is
- * different from the normal view.
- *
- * Implementation and usage
- *
- * GGTT views are implemented using VMAs and are distinguished via enum
- * i915_ggtt_view_type and struct i915_ggtt_view.
- *
- * A new flavour of core GEM functions which work with GGTT bound objects were
- * added with the _ggtt_ infix, and sometimes with _view postfix to avoid
- * renaming in large amounts of code. They take the struct i915_ggtt_view
- * parameter encapsulating all metadata required to implement a view.
- *
- * As a helper for callers which are only interested in the normal view,
- * globally const i915_ggtt_view_normal singleton instance exists. All old core
- * GEM API functions, the ones not taking the view parameter, are operating on,
- * or with the normal GGTT view.
- *
- * Code wanting to add or use a new GGTT view needs to:
- *
- * 1. Add a new enum with a suitable name.
- * 2. Extend the metadata in the i915_ggtt_view structure if required.
- * 3. Add support to i915_get_vma_pages().
- *
- * New views are required to build a scatter-gather table from within the
- * i915_get_vma_pages function. This table is stored in the vma.ggtt_view and
- * exists for the lifetime of an VMA.
- *
- * Core API is designed to have copy semantics which means that passed in
- * struct i915_ggtt_view does not need to be persistent (left around after
- * calling the core API functions).
- *

+ * DOC: Global GTT views
+ *
+ * Background and previous state
+ *
+ * Historically objects could exists (be bound) in global GTT space only as
+ * singular instances with a view representing all of the object's backing pages
+ * in a linear fashion. This view will be called a normal view.
+ *
+ * To support multiple views of the same object, where the number of mapped
+ * pages is not equal to the backing store, or where the layout of the pages
+ * is not linear, concept of a GGTT view was added.
+ *
+ * One example of an alternative view is a stereo display driven by a single
+ * image. In this case we would have a framebuffer looking like this
+ * (2x2 pages):
+ *
+ * 12
+ * 34
+ *
+ * Above would represent a normal GGTT view as normally mapped for GPU or CPU
+ * rendering. In contrast, fed to the display engine would be an alternative
+ * view which could look something like this:
+ *
+ * 1212
+ * 3434
+ *
+ * In this example both the size and layout of pages in the alternative view is
+ * different from the normal view.
+ *
+ * Implementation and usage
+ *
+ * GGTT views are implemented using VMAs and are distinguished via enum
+ * i915_ggtt_view_type and struct i915_ggtt_view.
+ *
+ * A new flavour of core GEM functions which work with GGTT bound objects were
+ * added with the _ggtt_ infix, and sometimes with _view postfix to avoid
+ * renaming in large amounts of code. They take the struct i915_ggtt_view
+ * parameter encapsulating all metadata required to implement a view.
+ *
+ * As a helper for callers which are only interested in the normal view,
+ * globally const i915_ggtt_view_normal singleton instance exists. All old core
+ * GEM API functions, the ones not taking the view parameter, are operating on,
+ * or with the normal GGTT view.
+ *
+ * Code wanting to add or use a new GGTT view needs to:

+ * DOC: Driver for the ARM FrameBuffer Compression Decoders
+ *
+ * The Amlogic GXM and G12A SoC families embeds an AFBC Decoder,
+ * to decode compressed buffers generated by the ARM Mali GPU.
+ *
+ * For the GXM Family, Amlogic designed their own Decoder, named in
+ * the vendor source as "MESON_AFBC", and a single decoder is available
+ * for the 2 OSD planes.
+ * This decoder is compatible with the AFBC 1.0 specifications and the
+ * Mali T820 GPU capabilities.
+ * It supports :
+ * - basic AFBC buffer for RGB32 only, thus YTR feature is mandatory
+ * - SPARSE layout and SPLIT layout
+ * - only 16x16 superblock
+ *
+ * The decoder reads the data from the SDRAM, decodes and sends the
+ * decoded pixel stream to the OSD1 Plane pixel composer.
+ *
+ * For the G12A Family, Amlogic integrated an ARM AFBC Decoder, named
+ * in the vendor source as "MALI_AFBC", and the decoder can decode up
+ * to 4 surfaces, one for each of the 4 available OSDs.
+ * This decoder is compatible with the AFBC 1.2 specifications for the
+ * Mali G31 and G52 GPUs.
+ * Is supports :
+ * - basic AFBC buffer for multiple RGB and YUV pixel formats
+ * - SPARSE layout and SPLIT layout
+ * - 16x16 and 32x8 "wideblk" superblocks
+ * - Tiled header
+ *
+ * The ARM AFBC Decoder independent from the VPU Pixel Pipeline, so
+ * the ARM AFBC Decoder reads the data from the SDRAM then decodes
+ * into a private internal physical address where the OSD1 Plane pixel
+ * composer unpacks the decoded data.

- * The struct nvkm_msgqueue (named so for lack of better candidate) manages
- * a firmware (typically, NVIDIA signed firmware) running under a given falcon.
- *
- * Such firmwares expect to receive commands (through one or several command
- * queues) and will reply to such command by sending messages (using one
- * message queue).
- *
- * Each firmware can support one or several units - ACR for managing secure
- * falcons, PMU for power management, etc. A unit can be seen as a class to
- * which command can be sent.
- *
- * One usage example would be to send a command to the SEC falcon to ask it to
- * reset a secure falcon. The SEC falcon will receive the command, process it,
- * and send a message to signal success or failure. Only when the corresponding
- * message is received can the requester assume the request has been processed.
- *
- * Since we expect many variations between the firmwares NVIDIA will release
- * across GPU generations, this library is built in a very modular way. Message
- * formats and queues details (such as number of usage) are left to
- * specializations of struct nvkm_msgqueue, while the functions in msgqueue.c

- * Secure boot is the process by which NVIDIA-signed firmware is loaded into
- * some of the falcons of a GPU. For production devices this is the only way
- * for the firmware to access useful (but sensitive) registers.
- *
- * A Falcon microprocessor supporting advanced security modes can run in one of
- * three modes:
- *
- * - Non-secure (NS). In this mode, functionality is similar to Falcon
- * architectures before security modes were introduced (pre-Maxwell), but
- * capability is restricted. In particular, certain registers may be
- * inaccessible for reads and/or writes, and physical memory access may be
- * disabled (on certain Falcon instances). This is the only possible mode that
- * can be used if you don't have microcode cryptographically signed by NVIDIA.
- *
- * - Heavy Secure (HS). In this mode, the microprocessor is a black box - it's
- * not possible to read or write any Falcon internal state or Falcon registers
- * from outside the Falcon (for example, from the host system). The only way
- * to enable this mode is by loading microcode that has been signed by NVIDIA.
- * (The loading process involves tagging the IMEM block as secure, writing the
- * signature into a Falcon register, and starting execution. The hardware will
- * validate the signature, and if valid, grant HS privileges.)
- *
- * - Light Secure (LS). In this mode, the microprocessor has more privileges
- * than NS but fewer than HS. Some of the microprocessor state is visible to
- * host software to ease debugging. The only way to enable this mode is by HS
- * microcode enabling LS mode. Some privileges available to HS mode are not
- * available here. LS mode is introduced in GM20x.
- *
- * Secure boot consists in temporarily switching a HS-capable falcon (typically
- * PMU) into HS mode in order to validate the LS firmwares of managed falcons,
- * load them, and switch managed falcons into LS mode. Once secure boot
- * completes, no falcon remains in HS mode.
- *
- * Secure boot requires a write-protected memory region (WPR) which can only be
- * written by the secure falcon. On dGPU, the driver sets up the WPR region in
- * video memory. On Tegra, it is set up by the bootloader and its location and
- * size written into memory controller registers.
- *
- * The secure boot process takes place as follows:
- *
- * 1) A LS blob is constructed that contains all the LS firmwares we want to
- * load, along with their signatures and bootloaders.
- *
- * 2) A HS blob (also called ACR) is created that contains the signed HS
- * firmware in charge of loading the LS firmwares into their respective
- * falcons.
- *
- * 3) The HS blob is loaded (via its own bootloader) and executed on the
- * HS-capable falcon. It authenticates itself, switches the secure falcon to
- * HS mode and setup the WPR region around the LS blob (dGPU) or copies the
- * LS blob into the WPR region (Tegra).
- *
- * 4) The LS blob is now secure from all external tampering. The HS falcon
- * checks the signatures of the LS firmwares and, if valid, switches the
- * managed falcons to LS mode and makes them ready to run the LS firmware.
- *
- * 5) The managed falcons remain in LS mode and can be started.

+ * Enabling CSI2 LDO shorts it to core supply. It is crucial the 2 CSI2

- * serial ports, we use dynamic serial port discovery that the serial.c
- * driver uses for pci/pnp ports (there is an entry for the SGI ioc3

- * port 0. So, we just use one serial port from each ioc3 (since the
- * serial driver adds addresses to get to higher ports).
- *
- * The first one to do a register_console becomes the preferred console
- * (if there is no kernel command line console= directive). /dev/console
- * (ie 5, 1) is then "aliased" into the device number returned by the
- * "device" routine referred to in this console structure
- * (ip27prom_console_dev).

- * Also look in ip27-pci.c:pci_fixup_ioc3() for some comments on working

+ * viewport -- we can map the outbound memory in or after 3GB and even

+ * will know to send outbound memory downstream and everything else

+ *
+ * For example:
+ *
+ * - The best-case scenario, memory up to 3GB, is to place the inbound

+ * as well, since some devices require a 32bit MSI target address.
+ *
+ * - If the system memory is 4GB or larger we cannot start the inbound

+ * outbound memory @ 3GB). So instead it will start at the 1x

-TODO: Remove in late 2019 unless there are users
-
-
-I tried to find any indication of whether the capi drivers are
-still in use, and have not found anything from a long time ago.
-
-With public ISDN networks almost completely shut down over the past 12
-months, there is very little you can actually do with this hardware. The
-main remaining use case would be to connect ISDN voice phones to an
-in-house installation with Asterisk or LCR, but anyone trying this in
-turn seems to be using either the mISDN driver stack, or out-of-tree
-drivers from the hardware vendors.
-
-I may of course have missed something, so I would suggest moving
-these into drivers/staging/ just in case someone still uses one
-of the three remaining in-kernel drivers (avm, hysdn, gigaset).
-
-If nobody complains, we can remove them entirely in six months,
-or otherwise move the core code and any drivers that are still
-needed back into drivers/isdn.

+* Fix serialization on subdev ops.
+* Don't use v4l2_async_notifier_parse_fwnode_endpoints_by_port().
+e.g. isp_parse_of_endpoints in drivers/media/platform/omap3isp/isp.c
+cio2_parse_firmware in drivers/media/pci/intel/ipu3/ipu3-cio2.c.
+* Fix pad format size for statistics and parameters entities.
+* Use threaded interrupt for rkisp1_stats_isr(), remove work queue.
+* Fix checkpatch errors.
+* Make sure uapi structs have the same size and layout in 32 and 62 bits,
+and that there are no holes in the structures (pahole is a utility that
+can be used to test this).
+* Review and comment every lock
+* Handle quantization
+* Document rkisp1-common.h
+* streaming paths (mainpath and selfpath) check if the other path is streaming
+in several places of the code, review this, specially that it doesn't seem it
+supports streaming from both paths at the same time.
+
+NOTES:
+* All v4l2-compliance test must pass.
+* Stats and params can be tested with libcamera and ChromiumOS stack.

- * at either HS or FS.
- * @otgint: OTG Interrupt (OTGInt)
- * The core sets this bit to indicate an OTG protocol event. The

This is a list of things that need to be done to get this driver out of the
staging directory.
- - I have to take a decision about secure link support. I can:
- - drop completely
- - keep it in an external patch (my preferred option)
- - replace call to mbedtls with kernel crypto API (necessitate a
- bunch of work)
- - pull mbedtls in kernel (non-realistic)
+ - All structures defined in hif_api_*.h are intended to sent/received to/from
+ hardware. All their members whould be declared __le32 or __le16.
+ See:
+ https://lore.kernel.org/lkml/20191111202852.GX26530@ZenIV.linux.org.uk
- - mac80211 interface does not (yet) have expected quality to be placed
- outside of staging:
- - Some processings are redundant with mac80211 ones
- - Many members from wfx_dev/wfx_vif can be retrieved from mac80211
- structures
- - Some functions are too complex
- - ...
+ - Once previous item done, it will be possible to audit the driver with
+ `sparse'. It will probably find tons of problems with big endian
+ architectures.
+
+ - hif_api_*.h whave been imported from firmware code. Some of the structures
+ are never used in driver.
+
+ - Driver try to maintains power save status of the stations. However, this
+ work is already done by mac80211. sta_asleep_mask and pspoll_mask should be
+ dropped.
+
+ - wfx_tx_queues_get() should be reworked. It currently try compute itself the
+ QoS policy. However, firmware already do the job. Firmware would prefer to
+ have a few packets in each queue and be able to choose itself which queue to
+ use.
+
+ - As suggested by Felix, rate control could be improved following this idea:
+ https://lore.kernel.org/lkml/3099559.gv3Q75KnN1@pc-42/
+
+ - When driver is about to loose BSS, it forge its own Null Func request (see
+ wfx_cqm_bssloss_sm()). It should use mechanism provided by mac80211.
+
+ - AP is actually is setup after a call to wfx_bss_info_changed(). Yet,
+ ieee80211_ops provide callback start_ap().
+
+ - The current process for joining a network is incredibly complex. Should be
+ reworked.
+
+ - Monitoring mode is not implemented despite being mandatory by mac80211.
+
+ - "compatible" value are not correct. They should be "vendor,chip". See:
+ https://lore.kernel.org/driverdev-devel/5226570.CMH5hVlZcI@pc-42
+
+ - The "state" field from wfx_vif should be replaced by "vif->type".
+
+ - It seems that wfx_upload_keys() is useless.
+
+ - "event_queue" from wfx_vif seems overkill. These event are rare and they
+ probably could be handled in a simpler fashion.
+
+ - Feature called "secure link" should be either developed (using kernel
+ crypto API) or dropped.
+
+ - In wfx_cmd_send(), "async" allow to send command without waiting the reply.
+ It may help in some situation, but it is not yet used. In add, it may cause
+ some trouble:
+ https://lore.kernel.org/driverdev-devel/alpine.DEB.2.21.1910041317381.2992@hadrien/
+ So, fix it (by replacing the mutex with a semaphore) or drop it.
+
+ - Chip support P2P, but driver does not implement it.
+
+ - Chip support kind of Mesh, but driver does not implement it.

+ * to data blocks mapped by an inode's attribute fork, and they have an upper
+ * size limit of 64k. Setting a value does not involve the XFS log.
+ *
+ * However, on a v5 filesystem, maximally sized remote attr values require one
+ * block more than 64k worth of space to hold both the remote attribute value
+ * header (64 bytes). On a 4k block filesystem this results in a 68k buffer;
+ * on a 64k block filesystem, this would be a 128k buffer. Note that the log
+ * format can only handle a dirty buffer of XFS_MAX_BLOCKSIZE length (64k).
+ * Therefore, we /must/ ensure that remote attribute value buffers never touch
+ * the logging system and therefore never have a log item.

- * struct bus_type - The bus type of the device
- *
- * @name: The name of the bus.
- * @dev_name: Used for subsystems to enumerate devices like ("foo%u", dev->id).
- * @dev_root: Default device to use as the parent.
- * @bus_groups: Default attributes of the bus.
- * @dev_groups: Default attributes of the devices on the bus.
- * @drv_groups: Default attributes of the device drivers on the bus.
- * @match: Called, perhaps multiple times, whenever a new device or driver
- * is added for this bus. It should return a positive value if the
- * given device can be handled by the given driver and zero
- * otherwise. It may also return error code if determining that
- * the driver supports the device is not possible. In case of
- * -EPROBE_DEFER it will queue the device for deferred probing.
- * @uevent: Called when a device is added, removed, or a few other things
- * that generate uevents to add the environment variables.
- * @probe: Called when a new device or driver add to this bus, and callback
- * the specific driver's probe to initial the matched device.
- * @sync_state: Called to sync device state to software state after all the
- * state tracking consumers linked to this device (present at
- * the time of late_initcall) have successfully bound to a
- * driver. If the device has no consumers, this function will
- * be called at late_initcall_sync level. If the device has
- * consumers that are never bound to a driver, this function
- * will never get called until they do.
- * @remove: Called when a device removed from this bus.
- * @shutdown: Called at shut-down time to quiesce the device.
- *
- * @online: Called to put the device back online (after offlining it).
- * @offline: Called to put the device offline for hot-removal. May fail.
- *
- * @suspend: Called when a device on this bus wants to go to sleep mode.
- * @resume: Called to bring a device on this bus out of sleep mode.
- * @num_vf: Called to find out how many virtual functions a device on this
- * bus supports.
- * @dma_configure: Called to setup DMA configuration on a device on
- * this bus.
- * @pm: Power management operations of this bus, callback the specific
- * device driver's pm-ops.
- * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
- * driver implementations to a bus and allow the driver to do
- * bus-specific setup
- * @p: The private data of the driver core, only the driver core can
- * touch this.
- * @lock_key: Lock class key for use by the lock validator
- * @need_parent_lock: When probing or removing a device on this bus, the
- * device core should lock the device's parent.
- *
- * A bus is a channel between the processor and one or more devices. For the
- * purposes of the device model, all devices are connected via a bus, even if
- * it is an internal, virtual, "platform" bus. Buses can plug into each other.
- * A USB controller is usually a PCI device, for example. The device model
- * represents the actual connections between buses and the devices they control.
- * A bus is represented by the bus_type structure. It contains the name, the
- * default attributes, the bus' methods, PM operations, and the driver core's
- * private data.

- * struct device_driver - The basic device driver structure
- * @name: Name of the device driver.
- * @bus: The bus which the device of this driver belongs to.
- * @owner: The module owner.
- * @mod_name: Used for built-in modules.
- * @suppress_bind_attrs: Disables bind/unbind via sysfs.
- * @probe_type: Type of the probe (synchronous or asynchronous) to use.
- * @of_match_table: The open firmware table.
- * @acpi_match_table: The ACPI match table.
- * @probe: Called to query the existence of a specific device,
- * whether this driver can work with it, and bind the driver
- * to a specific device.
- * @sync_state: Called to sync device state to software state after all the
- * state tracking consumers linked to this device (present at
- * the time of late_initcall) have successfully bound to a
- * driver. If the device has no consumers, this function will
- * be called at late_initcall_sync level. If the device has
- * consumers that are never bound to a driver, this function
- * will never get called until they do.
- * @remove: Called when the device is removed from the system to
- * unbind a device from this driver.
- * @shutdown: Called at shut-down time to quiesce the device.
- * @suspend: Called to put the device to sleep mode. Usually to a
- * low power state.
- * @resume: Called to bring a device from sleep mode.
- * @groups: Default attributes that get created by the driver core
- * automatically.
- * @dev_groups: Additional attributes attached to device instance once the
- * it is bound to the driver.
- * @pm: Power management operations of the device which matched
- * this driver.
- * @coredump: Called when sysfs entry is written to. The device driver
- * is expected to call the dev_coredump API resulting in a
- * uevent.
- * @p: Driver core's private data, no one other than the driver
- * core can touch this.
- *
- * The device driver-model tracks all of the drivers known to the system.
- * The main reason for this tracking is to enable the driver core to match
- * up drivers with new devices. Once drivers are known objects within the
- * system, however, a number of other things become possible. Device drivers
- * can export information and configuration variables that are independent
- * of any specific device.

+ * struct bus_type - The bus type of the device
+ *
+ * @name: The name of the bus.
+ * @dev_name: Used for subsystems to enumerate devices like ("foo%u", dev->id).
+ * @dev_root: Default device to use as the parent.
+ * @bus_groups: Default attributes of the bus.
+ * @dev_groups: Default attributes of the devices on the bus.
+ * @drv_groups: Default attributes of the device drivers on the bus.
+ * @match: Called, perhaps multiple times, whenever a new device or driver
+ * is added for this bus. It should return a positive value if the
+ * given device can be handled by the given driver and zero
+ * otherwise. It may also return error code if determining that
+ * the driver supports the device is not possible. In case of
+ * -EPROBE_DEFER it will queue the device for deferred probing.
+ * @uevent: Called when a device is added, removed, or a few other things
+ * that generate uevents to add the environment variables.
+ * @probe: Called when a new device or driver add to this bus, and callback
+ * the specific driver's probe to initial the matched device.
+ * @sync_state: Called to sync device state to software state after all the
+ * state tracking consumers linked to this device (present at
+ * the time of late_initcall) have successfully bound to a
+ * driver. If the device has no consumers, this function will
+ * be called at late_initcall_sync level. If the device has
+ * consumers that are never bound to a driver, this function
+ * will never get called until they do.
+ * @remove: Called when a device removed from this bus.
+ * @shutdown: Called at shut-down time to quiesce the device.
+ *
+ * @online: Called to put the device back online (after offlining it).
+ * @offline: Called to put the device offline for hot-removal. May fail.
+ *
+ * @suspend: Called when a device on this bus wants to go to sleep mode.
+ * @resume: Called to bring a device on this bus out of sleep mode.
+ * @num_vf: Called to find out how many virtual functions a device on this
+ * bus supports.
+ * @dma_configure: Called to setup DMA configuration on a device on
+ * this bus.
+ * @pm: Power management operations of this bus, callback the specific
+ * device driver's pm-ops.
+ * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
+ * driver implementations to a bus and allow the driver to do
+ * bus-specific setup
+ * @p: The private data of the driver core, only the driver core can
+ * touch this.
+ * @lock_key: Lock class key for use by the lock validator
+ * @need_parent_lock: When probing or removing a device on this bus, the
+ * device core should lock the device's parent.
+ *
+ * A bus is a channel between the processor and one or more devices. For the
+ * purposes of the device model, all devices are connected via a bus, even if
+ * it is an internal, virtual, "platform" bus. Buses can plug into each other.
+ * A USB controller is usually a PCI device, for example. The device model
+ * represents the actual connections between buses and the devices they control.
+ * A bus is represented by the bus_type structure. It contains the name, the
+ * default attributes, the bus' methods, PM operations, and the driver core's
+ * private data.

+ * to a specific device.
+ * @sync_state: Called to sync device state to software state after all the
+ * state tracking consumers linked to this device (present at
+ * the time of late_initcall) have successfully bound to a
+ * driver. If the device has no consumers, this function will
+ * be called at late_initcall_sync level. If the device has
+ * consumers that are never bound to a driver, this function
+ * will never get called until they do.
+ * @remove: Called when the device is removed from the system to
+ * unbind a device from this driver.
+ * @shutdown: Called at shut-down time to quiesce the device.
+ * @suspend: Called to put the device to sleep mode. Usually to a
+ * low power state.

+ * Locking:
+ *
+ * Accesses to a message queue are synchronized by acquiring info->lock.
+ *
+ * There are two notable exceptions:
+ * - The actual wakeup of a sleeping task is performed using the wake_q
+ * framework. info->lock is already released when wake_up_q is called.
+ * - The exit codepaths after sleeping check ext_wait_queue->state without
+ * any locks. If it is STATE_READY, then the syscall is completed without
+ * acquiring info->lock.
+ *
+ * MQ_BARRIER:
+ * To achieve proper release/acquire memory barrier pairing, the state is set to
+ * STATE_READY with smp_store_release(), and it is read with READ_ONCE followed
+ * by smp_acquire__after_ctrl_dep(). In addition, wake_q_add_safe() is used.
+ *
+ * This prevents the following races:
+ *
+ * 1) With the simple wake_q_add(), the task could be gone already before
+ * the increase of the reference happens
+ * Thread A
+ * Thread B
+ * WRITE_ONCE(wait.state, STATE_NONE);
+ * schedule_hrtimeout()
+ * wake_q_add(A)
+ * if (cmpxchg()) // success
+ * ->state = STATE_READY (reordered)
+ * <timeout returns>
+ * if (wait.state == STATE_READY) return;
+ * sysret to user space
+ * sys_exit()
+ * get_task_struct() // UaF
+ *
+ * Solution: Use wake_q_add_safe() and perform the get_task_struct() before
+ * the smp_store_release() that does ->state = STATE_READY.
+ *
+ * 2) Without proper _release/_acquire barriers, the woken up task
+ * could read stale data
+ *

+ * do_mq_timedreceive

+ * msg_ptr = wait.msg; // Access to stale data!
+ * receiver->msg = message; (reordered)
+ *
+ * Solution: use _release and _acquire barriers.
+ *
+ * 3) There is intentionally no barrier when setting current->state
+ * to TASK_INTERRUPTIBLE: spin_unlock(&info->lock) provides the

+
+config EVENT_TRACE_STARTUP_TEST
+ bool "Run selftest on trace events"
+ depends on FTRACE_STARTUP_TEST
+ default y
+ help
+ This option performs a test on all trace events in the system.
+ It basically just enables each event and runs some code that
+ will trigger events (not necessarily the event it enables)
+ This may take some time run as there are a lot of events.
+
+config EVENT_TRACE_TEST_SYSCALLS
+ bool "Run selftest on syscall events"
+ depends on EVENT_TRACE_STARTUP_TEST
+ help
+ This option will also enable testing every syscall event.
+ It only enables the event and disables it and runs various loads
+ with the event enabled. This adds a bit more time for kernel boot
+ up since it runs this on every system call defined.
+
+ TBD - enable a way to actually call the syscalls as we test their
+ events
+
+config RING_BUFFER_STARTUP_TEST
+ bool "Ring buffer startup self test"
+ depends on RING_BUFFER
+ help
+ Run a simple self test on the ring buffer on boot up. Late in the
+ kernel boot sequence, the test will start that kicks off
+ a thread per cpu. Each thread will write various size events
+ into the ring buffer. Another thread is created to send IPIs
+ to each of the threads, where the IPI handler will also write
+ to the ring buffer, to test/stress the nesting ability.
+ If any anomalies are discovered, a warning will be displayed
+ and all ring buffers will be disabled.
+
+ The test runs for 10 seconds. This will slow your boot time
+ by at least 10 more seconds.
+
+ At the end of the test, statics and more checks are done.
+ It will output the stats of each per cpu buffer. What
+ was written, the sizes, what was read, what was lost, and
+ other similar details.
+
+ If unsure, say N
+
+config MMIOTRACE_TEST
+ tristate "Test module for mmiotrace"
+ depends on MMIOTRACE && m
+ help
+ This is a dumb module for testing mmiotrace. It is very dangerous
+ as it will write garbage to IO memory starting at a given address.
+ However, it should be safe to use on e.g. unused portion of VRAM.
+
+ Say N, unless you absolutely know what you are doing.
+
+config PREEMPTIRQ_DELAY_TEST
+ tristate "Test module to create a preempt / IRQ disable delay thread to test latency tracers"
+ depends on m
+ help
+ Select this option to build a test module that can help test latency
+ tracers by executing a preempt or irq disable section with a user
+ configurable delay. The module busy waits for the duration of the
+ critical section.
+
+ For example, the following invocation generates a burst of three
+ irq-disabled critical sections for 500us:
+ modprobe preemptirq_delay_test test_mode=irq delay=500 burst_size=3
+
+ If unsure, say N
+
+config SYNTH_EVENT_GEN_TEST
+ tristate "Test module for in-kernel synthetic event generation"
+ depends on HIST_TRIGGERS
+ help
+ This option creates a test module to check the base
+ functionality of in-kernel synthetic event definition and
+ generation.
+
+ To test, insert the module, and then check the trace buffer
+ for the generated sample events.
+
+ If unsure, say N.
+
+config KPROBE_EVENT_GEN_TEST
