Merge branch 'iomap-write' into linux-gfs2/for-next
Pull in the gfs2 iomap-write changes: Tweak the existing code to
properly support iomap write and eliminate an unnecessary special case
in gfs2_block_map. Implement iomap write support for buffered and
direct I/O. Simplify some of the existing code and eliminate code that
is no longer used:
gfs2: Remove gfs2_write_{begin,end}
gfs2: iomap direct I/O support
gfs2: gfs2_extent_length cleanup
gfs2: iomap buffered write support
gfs2: Further iomap cleanups
This is based on the following changes on the xfs 'iomap-4.19-merge'
branch:
iomap: add private pointer to struct iomap
iomap: add a page_done callback
iomap: generic inline data handling
iomap: complete partial direct I/O writes synchronously
iomap: mark newly allocated buffer heads as new
fs: factor out a __generic_write_end helper

+Description:
+ Every rpmsg device is a communication channel with a remote
+ processor. Channels are identified by a textual name (see
+ /sys/bus/rpmsg/devices/.../name above) and have a local
+ ("source") rpmsg address, and remote ("destination") rpmsg
+ address.
+
+ The listening entity (or client) which communicates with a
+ remote processor is referred as rpmsg driver. The rpmsg device
+ and rpmsg driver are matched based on rpmsg device name and
+ rpmsg driver ID table.
+
+ This sysfs entry allows the rpmsg driver for a rpmsg device
+ to be specified which will override standard OF, ID table
+ and name matching.

+
+Generic Interface (GENI) based Qualcomm Universal Peripheral (QUP) wrapper
+is a programmable module for supporting a wide range of serial interfaces
+like UART, SPI, I2C, I3C, etc. A single QUP module can provide upto 8 Serial
+Interfaces, using its internal Serial Engines. The GENI Serial Engine QUP
+Wrapper controller is modeled as a node with zero or more child nodes each
+representing a serial engine.
+
+Required properties:
+- compatible: Must be "qcom,geni-se-qup".
+- reg: Must contain QUP register address and length.
+- clock-names: Must contain "m-ahb" and "s-ahb".
+- clocks: AHB clocks needed by the device.

+Supporting PMUs on RISC-V platforms
+==========================================
+Alan Kao <alankao@andestech.com>, Mar 2018
+
+Introduction
+------------
+
+As of this writing, perf_event-related features mentioned in The RISC-V ISA
+Privileged Version 1.10 are as follows:
+(please check the manual for more details)
+
+* [m|s]counteren
+* mcycle[h], cycle[h]
+* minstret[h], instret[h]
+* mhpeventx, mhpcounterx[h]
+
+With such function set only, porting perf would require a lot of work, due to
+the lack of the following general architectural performance monitoring features:
+
+* Enabling/Disabling counters
+ Counters are just free-running all the time in our case.
+* Interrupt caused by counter overflow
+ No such feature in the spec.
+* Interrupt indicator
+ It is not possible to have many interrupt ports for all counters, so an
+ interrupt indicator is required for software to tell which counter has
+ just overflowed.
+* Writing to counters
+ There will be an SBI to support this since the kernel cannot modify the
+ counters [1]. Alternatively, some vendor considers to implement
+ hardware-extension for M-S-U model machines to write counters directly.
+
+This document aims to provide developers a quick guide on supporting their
+PMUs in the kernel. The following sections briefly explain perf' mechanism
+and todos.
+
+You may check previous discussions here [1][2]. Also, it might be helpful
+to check the appendix for related kernel structures.
+
+
+1. Initialization
+-----------------
+
+*riscv_pmu* is a global pointer of type *struct riscv_pmu*, which contains
+various methods according to perf's internal convention and PMU-specific
+parameters. One should declare such instance to represent the PMU. By default,
+*riscv_pmu* points to a constant structure *riscv_base_pmu*, which has very
+basic support to a baseline QEMU model.
+
+Then he/she can either assign the instance's pointer to *riscv_pmu* so that
+the minimal and already-implemented logic can be leveraged, or invent his/her
+own *riscv_init_platform_pmu* implementation.
+
+In other words, existing sources of *riscv_base_pmu* merely provide a
+reference implementation. Developers can flexibly decide how many parts they
+can leverage, and in the most extreme case, they can customize every function
+according to their needs.
+
+
+2. Event Initialization
+-----------------------
+
+When a user launches a perf command to monitor some events, it is first
+interpreted by the userspace perf tool into multiple *perf_event_open*
+system calls, and then each of them calls to the body of *event_init*
+member function that was assigned in the previous step. In *riscv_base_pmu*'s
+case, it is *riscv_event_init*.
+
+The main purpose of this function is to translate the event provided by user
+into bitmap, so that HW-related control registers or counters can directly be
+manipulated. The translation is based on the mappings and methods provided in
+*riscv_pmu*.
+
+Note that some features can be done in this stage as well:
+
+(1) interrupt setting, which is stated in the next section;
+(2) privilege level setting (user space only, kernel space only, both);
+(3) destructor setting. Normally it is sufficient to apply *riscv_destroy_event*;
+(4) tweaks for non-sampling events, which will be utilized by functions such as
+*perf_adjust_period*, usually something like the follows:
+
+if (!is_sampling_event(event)) {
+ hwc->sample_period = x86_pmu.max_period;
+ hwc->last_period = hwc->sample_period;
+ local64_set(&hwc->period_left, hwc->sample_period);
+}
+
+In the case of *riscv_base_pmu*, only (3) is provided for now.
+
+
+3. Interrupt
+------------
+
+3.1. Interrupt Initialization
+
+This often occurs at the beginning of the *event_init* method. In common
+practice, this should be a code segment like
+
+int x86_reserve_hardware(void)
+{
+ int err = 0;
+
+ if (!atomic_inc_not_zero(&pmc_refcount)) {
+ mutex_lock(&pmc_reserve_mutex);
+ if (atomic_read(&pmc_refcount) == 0) {
+ if (!reserve_pmc_hardware())
+ err = -EBUSY;
+ else
+ reserve_ds_buffers();
+ }
+ if (!err)
+ atomic_inc(&pmc_refcount);
+ mutex_unlock(&pmc_reserve_mutex);
+ }
+
+ return err;
+}
+
+And the magic is in *reserve_pmc_hardware*, which usually does atomic
+operations to make implemented IRQ accessible from some global function pointer.
+*release_pmc_hardware* serves the opposite purpose, and it is used in event
+destructors mentioned in previous section.
+
+(Note: From the implementations in all the architectures, the *reserve/release*
+pair are always IRQ settings, so the *pmc_hardware* seems somehow misleading.
+It does NOT deal with the binding between an event and a physical counter,
+which will be introduced in the next section.)
+
+3.2. IRQ Structure
+
+Basically, a IRQ runs the following pseudo code:
+
+for each hardware counter that triggered this overflow
+
+ get the event of this counter
+
+ // following two steps are defined as *read()*,
+ // check the section Reading/Writing Counters for details.
+ count the delta value since previous interrupt
+ update the event->count (# event occurs) by adding delta, and
+ event->hw.period_left by subtracting delta
+
+ if the event overflows
+ sample data
+ set the counter appropriately for the next overflow
+
+ if the event overflows again
+ too frequently, throttle this event
+ fi
+ fi
+
+end for
+
+However as of this writing, none of the RISC-V implementations have designed an
+interrupt for perf, so the details are to be completed in the future.
+
+4. Reading/Writing Counters
+---------------------------
+
+They seem symmetric but perf treats them quite differently. For reading, there
+is a *read* interface in *struct pmu*, but it serves more than just reading.
+According to the context, the *read* function not only reads the content of the
+counter (event->count), but also updates the left period to the next interrupt
+(event->hw.period_left).
+
+But the core of perf does not need direct write to counters. Writing counters
+is hidden behind the abstraction of 1) *pmu->start*, literally start counting so one
+has to set the counter to a good value for the next interrupt; 2) inside the IRQ
+it should set the counter to the same resonable value.
+
+Reading is not a problem in RISC-V but writing would need some effort, since
+counters are not allowed to be written by S-mode.
+
+
+5. add()/del()/start()/stop()
+-----------------------------
+
+Basic idea: add()/del() adds/deletes events to/from a PMU, and start()/stop()
+starts/stop the counter of some event in the PMU. All of them take the same
+arguments: *struct perf_event *event* and *int flag*.
+
+Consider perf as a state machine, then you will find that these functions serve
+as the state transition process between those states.
+Three states (event->hw.state) are defined:
+
+* PERF_HES_STOPPED: the counter is stopped
+* PERF_HES_UPTODATE: the event->count is up-to-date
+* PERF_HES_ARCH: arch-dependent usage ... we don't need this for now
+
+A normal flow of these state transitions are as follows:
+
+* A user launches a perf event, resulting in calling to *event_init*.
+* When being context-switched in, *add* is called by the perf core, with a flag
+ PERF_EF_START, which means that the event should be started after it is added.
+ At this stage, a general event is bound to a physical counter, if any.
+ The state changes to PERF_HES_STOPPED and PERF_HES_UPTODATE, because it is now
+ stopped, and the (software) event count does not need updating.
+** *start* is then called, and the counter is enabled.
+ With flag PERF_EF_RELOAD, it writes an appropriate value to the counter (check
+ previous section for detail).
+ Nothing is written if the flag does not contain PERF_EF_RELOAD.
+ The state now is reset to none, because it is neither stopped nor updated
+ (the counting already started)
+* When being context-switched out, *del* is called. It then checks out all the
+ events in the PMU and calls *stop* to update their counts.
+** *stop* is called by *del*
+ and the perf core with flag PERF_EF_UPDATE, and it often shares the same
+ subroutine as *read* with the same logic.
+ The state changes to PERF_HES_STOPPED and PERF_HES_UPTODATE, again.
+
+** Life cycle of these two pairs: *add* and *del* are called repeatedly as
+ tasks switch in-and-out; *start* and *stop* is also called when the perf core
+ needs a quick stop-and-start, for instance, when the interrupt period is being
+ adjusted.
+
+Current implementation is sufficient for now and can be easily extended to
+features in the future.
+
+A. Related Structures
+---------------------
+
+* struct pmu: include/linux/perf_event.h
+* struct riscv_pmu: arch/riscv/include/asm/perf_event.h
+
+ Both structures are designed to be read-only.
+
+ *struct pmu* defines some function pointer interfaces, and most of them take
+*struct perf_event* as a main argument, dealing with perf events according to
+perf's internal state machine (check kernel/events/core.c for details).
+
+ *struct riscv_pmu* defines PMU-specific parameters. The naming follows the
+convention of all other architectures.
+
+* struct perf_event: include/linux/perf_event.h
+* struct hw_perf_event
+
+ The generic structure that represents perf events, and the hardware-related
+details.
+
+* struct riscv_hw_events: arch/riscv/include/asm/perf_event.h
+
+ The structure that holds the status of events, has two fixed members:
+the number of events and the array of the events.

+ * GENI based QUP is a highly-flexible and programmable module for supporting
+ * a wide range of serial interfaces like UART, SPI, I2C, I3C, etc. A single
+ * QUP module can provide upto 8 serial interfaces, using its internal
+ * serial engines. The actual configuration is determined by the target
+ * platform configuration. The protocol supported by each interface is
+ * determined by the firmware loaded to the serial engine. Each SE consists
+ * of a DMA Engine and GENI sub modules which enable serial engines to
+ * support FIFO and DMA modes of operation.

From the initial code review:
The main thing you need to do is to implement all the controls using the
-control framework (see Documentation/video4linux/v4l2-controls.txt).
+control framework (see Documentation/media/kapi/v4l2-controls.rst).
Most drivers are by now converted to the control framework, so you will
find many examples of how to do this in drivers/media/radio.

- tristate "Kernel automounter version 4 support (also supports v3 and v5)"
- default n
- depends on AUTOFS_FS = n
- help
- The automounter is a tool to automatically mount remote file systems
- on demand. This implementation is partially kernel-based to reduce
- overhead in the already-mounted case; this is unlike the BSD
- automounter (amd), which is a pure user space daemon.
-
- To use the automounter you need the user-space tools from
- <https://www.kernel.org/pub/linux/daemons/autofs/>; you also want
- to answer Y to "NFS file system support", below.
-
- This module is in the process of being renamed from autofs4 to
- autofs. Since autofs is now the only module that provides the
- autofs file system the module is not version 4 specific.
-
- The autofs4 module is now built from the source located in
- fs/autofs. The autofs4 directory and its configuration entry
- will be removed two kernel versions from the inclusion of this
- change.
-
- Changes that will need to be made should be limited to:
- - source include statments should be changed from autofs_fs4.h to
- autofs_fs.h since these two header files have been merged.
- - user space scripts that manually load autofs4.ko should be
- changed to load autofs.ko. But since the module directory name
- and the module name are the same as the file system name there
- is no need to manually load module.
- - any "alias autofs autofs4" will need to be removed.
- - due to the autofs4 module directory name not being the same as
- its file system name autoloading didn't work properly. Because
- of this kernel configurations would often build the module into
- the kernel. This may have resulted in selinux policies that will
- prevent the autofs module from autoloading and will need to be
- updated.
-
- Please configure AUTOFS_FS instead of AUTOFS4_FS from now on.
-
- NOTE: Since the modules autofs and autofs4 use the same file system
- type name of "autofs" only one can be built. The "depends"
- above will result in AUTOFS4_FS not appearing in .config for
- any setting of AUTOFS_FS other than n and AUTOFS4_FS will
- appear under the AUTOFS_FS entry otherwise which is intended
- to draw attention to the module rename change.
