 Another wriggle to watch out for is your on-disk block allocation strategy.

+Abstract:
 
-trace_state
+This document describes the functions and the interfaces of the method
+tracing facility.
+
+1. Functionalities and usage examples:
+
+   ACPICA provides method tracing capability. And two functions are
+   currently implemented using this capability.
+
+   A. Log reducer
+   ACPICA subsystem provides debugging outputs when CONFIG_ACPI_DEBUG is
+   enabled. The debugging messages which are deployed via
+   ACPI_DEBUG_PRINT() macro can be reduced at 2 levels - per-component
+   level (known as debug layer, configured via
+   /sys/module/acpi/parameters/debug_layer) and per-type level (known as
+   debug level, configured via /sys/module/acpi/parameters/debug_level).
+
+   But when the particular layer/level is applied to the control method
+   evaluations, the quantity of the debugging outputs may still be too
+   large to be put into the kernel log buffer. The idea thus is worked out
+   to only enable the particular debug layer/level (normally more detailed)
+   logs when the control method evaluation is started, and disable the
+   detailed logging when the control method evaluation is stopped.
+
+   The following command examples illustrate the usage of the "log reducer"
+   functionality:
+   a. Filter out the debug layer/level matched logs when control methods
+      are being evaluated:
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "enable" > trace_state
+   b. Filter out the debug layer/level matched logs when the specified
+      control method is being evaluated:
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method" > /sys/module/acpi/parameters/trace_state
+   c. Filter out the debug layer/level matched logs when the specified
+      control method is being evaluated for the first time:
+      # cd /sys/module/acpi/parameters
+      # echo "0xXXXXXXXX" > trace_debug_layer
+      # echo "0xYYYYYYYY" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method-once" > /sys/module/acpi/parameters/trace_state
+   Where:
+      0xXXXXXXXX/0xYYYYYYYY: Refer to Documentation/acpi/debug.txt for
+			     possible debug layer/level masking values.
+      \PPPP.AAAA.TTTT.HHHH: Full path of a control method that can be found
+			    in the ACPI namespace. It needn't be an entry
+			    of a control method evaluation.
+
+   B. AML tracer
+
+   There are special log entries added by the method tracing facility at
+   the "trace points" the AML interpreter starts/stops to execute a control
+   method, or an AML opcode. Note that the format of the log entries are
+   subject to change:
+     [    0.186427]   exdebug-0398 ex_trace_point        : Method Begin [0xf58394d8:\_SB.PCI0.LPCB.ECOK] execution.

+     [    0.186820]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905cc0:LEqual] execution.
+     [    0.187010]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905a20:-NamePath-] execution.
+     [    0.187214]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905a20:-NamePath-] execution.
+     [    0.187407]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905f60:One] execution.
+     [    0.187594]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905f60:One] execution.
+     [    0.187789]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905cc0:LEqual] execution.
+     [    0.187980]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905cc0:Return] execution.
+     [    0.188146]   exdebug-0398 ex_trace_point        : Opcode Begin [0xf5905f60:One] execution.
+     [    0.188334]   exdebug-0398 ex_trace_point        : Opcode End [0xf5905f60:One] execution.

+
+   Developers can utilize these special log entries to track the AML
+   interpretion, thus can aid issue debugging and performance tuning. Note
+   that, as the "AML tracer" logs are implemented via ACPI_DEBUG_PRINT()
+   macro, CONFIG_ACPI_DEBUG is also required to be enabled for enabling
+   "AML tracer" logs.
+
+   The following command examples illustrate the usage of the "AML tracer"
+   functionality:
+   a. Filter out the method start/stop "AML tracer" logs when control
+      methods are being evaluated:
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "enable" > trace_state
+   b. Filter out the method start/stop "AML tracer" when the specified
+      control method is being evaluated:
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method" > trace_state
+   c. Filter out the method start/stop "AML tracer" logs when the specified
+      control method is being evaluated for the first time:
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "method-once" > trace_state
+   d. Filter out the method/opcode start/stop "AML tracer" when the
+      specified control method is being evaluated:
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "opcode" > trace_state
+   e. Filter out the method/opcode start/stop "AML tracer" when the
+      specified control method is being evaluated for the first time:
+      # cd /sys/module/acpi/parameters
+      # echo "0x80" > trace_debug_layer
+      # echo "0x10" > trace_debug_level
+      # echo "\PPPP.AAAA.TTTT.HHHH" > trace_method_name
+      # echo "opcode-opcode" > trace_state
+
+  Note that all above method tracing facility related module parameters can
+  be used as the boot parameters, for example:
+      acpi.trace_debug_layer=0x80 acpi.trace_debug_level=0x10 \
+      acpi.trace_method_name=\_SB.LID0._LID acpi.trace_state=opcode-once
+
+2. Interface descriptions:
+
+   All method tracing functions can be configured via ACPI module
+   parameters that are accessible at /sys/module/acpi/parameters/:
+
+   trace_method_name
+	The full path of the AML method that the user wants to trace.
+	Note that the full path shouldn't contain the trailing "_"s in its
+	name segments but may contain "\" to form an absolute path.
+
+   trace_debug_layer
+	The temporary debug_layer used when the tracing feature is enabled.
+	Using ACPI_EXECUTER (0x80) by default, which is the debug_layer
+	used to match all "AML tracer" logs.
+
+   trace_debug_level
+	The temporary debug_level used when the tracing feature is enabled.
+	Using ACPI_LV_TRACE_POINT (0x10) by default, which is the
+	debug_level used to match all "AML tracer" logs.
+
+   trace_state
 	The status of the tracing feature.
-
-	"enabled" means this feature is enabled
-	and the AML method is traced every time it's executed.
-
-	"1" means this feature is enabled and the AML method
-	will only be traced during the next execution.
-
-	"disabled" means this feature is disabled.
-	Users can enable/disable this debug tracing feature by
-	"echo string > /sys/module/acpi/parameters/trace_state".
-	"string" should be one of "enable", "disable" and "1".
+	Users can enable/disable this debug tracing feature by executing
+	the following command:
+	    # echo string > /sys/module/acpi/parameters/trace_state
+	Where "string" should be one of the followings:
+	"disable"
+	    Disable the method tracing feature.
+	"enable"
+	    Enable the method tracing feature.
+	    ACPICA debugging messages matching
+	    "trace_debug_layer/trace_debug_level" during any method
+	    execution will be logged.
+	"method"
+	    Enable the method tracing feature.
+	    ACPICA debugging messages matching
+	    "trace_debug_layer/trace_debug_level" during method execution

+						   Process Number Controller
+						   =========================
+
+Abstract
+--------
+
+The process number controller is used to allow a cgroup hierarchy to stop any
+new tasks from being fork()'d or clone()'d after a certain limit is reached.
+
+Since it is trivial to hit the task limit without hitting any kmemcg limits in
+place, PIDs are a fundamental resource. As such, PID exhaustion must be
+preventable in the scope of a cgroup hierarchy by allowing resource limiting of
+the number of tasks in a cgroup.
+
+Usage
+-----
+
+In order to use the `pids` controller, set the maximum number of tasks in
+pids.max (this is not available in the root cgroup for obvious reasons). The
+number of processes currently in the cgroup is given by pids.current.
+
+Organisational operations are not blocked by cgroup policies, so it is possible
+to have pids.current > pids.max. This can be done by either setting the limit to
+be smaller than pids.current, or attaching enough processes to the cgroup such
+that pids.current > pids.max. However, it is not possible to violate a cgroup
+policy through fork() or clone(). fork() and clone() will return -EAGAIN if the
+creation of a new process would cause a cgroup policy to be violated.
+
+To set a cgroup to have no limit, set pids.max to "max". This is the default for
+all new cgroups (N.B. that PID limits are hierarchical, so the most stringent
+limit in the hierarchy is followed).
+
+pids.current tracks all child cgroup hierarchies, so parent/pids.current is a
+superset of parent/child/pids.current.
+
+Example
+-------
+
+First, we mount the pids controller:
+# mkdir -p /sys/fs/cgroup/pids
+# mount -t cgroup -o pids none /sys/fs/cgroup/pids
+
+Then we create a hierarchy, set limits and attach processes to it:
+# mkdir -p /sys/fs/cgroup/pids/parent/child
+# echo 2 > /sys/fs/cgroup/pids/parent/pids.max
+# echo $$ > /sys/fs/cgroup/pids/parent/cgroup.procs
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+#
+
+It should be noted that attempts to overcome the set limit (2 in this case) will
+fail:
+
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+# ( /bin/echo "Here's some processes for you." | cat )
+sh: fork: Resource temporary unavailable
+#
+
+Even if we migrate to a child cgroup (which doesn't have a set limit), we will
+not be able to overcome the most stringent limit in the hierarchy (in this case,
+parent's):
+
+# echo $$ > /sys/fs/cgroup/pids/parent/child/cgroup.procs
+# cat /sys/fs/cgroup/pids/parent/pids.current
+2
+# cat /sys/fs/cgroup/pids/parent/child/pids.current
+2
+# cat /sys/fs/cgroup/pids/parent/child/pids.max
+max
+# ( /bin/echo "Here's some processes for you." | cat )
+sh: fork: Resource temporary unavailable
+#
+
+We can set a limit that is smaller than pids.current, which will stop any new
+processes from being forked at all (note that the shell itself counts towards
+pids.current):
+
+# echo 1 > /sys/fs/cgroup/pids/parent/pids.max
+# /bin/echo "We can't even spawn a single process now."
+sh: fork: Resource temporary unavailable
+# echo 0 > /sys/fs/cgroup/pids/parent/pids.max
+# /bin/echo "We can't even spawn a single process now."
+sh: fork: Resource temporary unavailable

+5-3-2. Control Knobs
+
+- Settings for a single feature should generally be implemented in a
+  single file.
+
+- In general, the root cgroup should be exempt from resource control
+  and thus shouldn't have resource control knobs.
+
+- If a controller implements ratio based resource distribution, the
+  control knob should be named "weight" and have the range [1, 10000]
+  and 100 should be the default value.  The values are chosen to allow
+  enough and symmetric bias in both directions while keeping it
+  intuitive (the default is 100%).
+
+- If a controller implements an absolute resource guarantee and/or
+  limit, the control knobs should be named "min" and "max"
+  respectively.  If a controller implements best effort resource
+  gurantee and/or limit, the control knobs should be named "low" and
+  "high" respectively.
+
+  In the above four control files, the special token "max" should be
+  used to represent upward infinity for both reading and writing.
+
+- If a setting has configurable default value and specific overrides,
+  the default settings should be keyed with "default" and appear as
+  the first entry in the file.  Specific entries can use "default" as
+  its value to indicate inheritance of the default value.

+- blkio is renamed to io.  The interface is overhauled anyway.  The
+  new name is more in line with the other two major controllers, cpu
+  and memory, and better suited given that it may be used for cgroup
+  writeback without involving block layer.

+Discard Support
+---------------
+The implementation of discard support among hardware vendors varies.
+When a block is discarded, some storage devices will return zeroes when
+the block is read.  These devices set the 'discard_zeroes_data'
+attribute.  Other devices will return random data.  Confusingly, some
+devices that advertise 'discard_zeroes_data' will not reliably return
+zeroes when discarded blocks are read!  Since RAID 4/5/6 uses blocks
+from a number of devices to calculate parity blocks and (for performance
+reasons) relies on 'discard_zeroes_data' being reliable, it is important
+that the devices be consistent.  Blocks may be discarded in the middle
+of a RAID 4/5/6 stripe and if subsequent read results are not
+consistent, the parity blocks may be calculated differently at any time;
+making the parity blocks useless for redundancy.  It is important to
+understand how your hardware behaves with discards if you are going to
+enable discards with RAID 4/5/6.
+
+Since the behavior of storage devices is unreliable in this respect,
+even when reporting 'discard_zeroes_data', by default RAID 4/5/6
+discard support is disabled -- this ensures data integrity at the
+expense of losing some performance.
+
+Storage devices that properly support 'discard_zeroes_data' are
+increasingly whitelisted in the kernel and can thus be trusted.
+
+For trusted devices, the following dm-raid module parameter can be set
+to safely enable discard support for RAID 4/5/6:
+    'devices_handle_discards_safely'

+Device Tree Clock bindins for CPU DVFS of Mediatek MT8173 SoC
+
+Required properties:
+- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
+- clock-names: Should contain the following:
+	"cpu"		- The multiplexer for clock input of CPU cluster.
+	"intermediate"	- A parent of "cpu" clock which is used as "intermediate" clock
+			  source (usually MAINPLL) when the original CPU PLL is under
+			  transition and not stable yet.
+	Please refer to Documentation/devicetree/bindings/clk/clock-bindings.txt for
+	generic clock consumer properties.
+- proc-supply: Regulator for Vproc of CPU cluster.
+
+Optional properties:
+- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
+	       needs to do "voltage tracking" to step by step scale up/down Vproc and
+	       Vsram to fit SoC specific needs. When absent, the voltage scaling
+	       flow is handled by hardware, hence no software "voltage tracking" is
+	       needed.

+Generic device tree bindings for I2C busses
+===========================================
+
+This document describes generic bindings which can be used to describe I2C
+busses in a device tree.
+
+Required properties
+-------------------
+
+- #address-cells  - should be <1>. Read more about addresses below.
+- #size-cells     - should be <0>.
+- compatible      - name of I2C bus controller following generic names
+		    recommended practice.
+
+For other required properties e.g. to describe register sets,
+clocks, etc. check the binding documentation of the specific driver.
+
+The cells properties above define that an address of children of an I2C bus
+are described by a single value. This is usually a 7 bit address. However,
+flags can be attached to the address. I2C_TEN_BIT_ADDRESS is used to mark a 10
+bit address. It is needed to avoid the ambiguity between e.g. a 7 bit address
+of 0x50 and a 10 bit address of 0x050 which, in theory, can be on the same bus.
+Another flag is I2C_OWN_SLAVE_ADDRESS to mark addresses on which we listen to
+be devices ourselves.
+
+Optional properties
+-------------------
+
+These properties may not be supported by all drivers. However, if a driver
+wants to support one of the below features, it should adapt the bindings below.
+
+- clock-frequency	- frequency of bus clock in Hz.
+- wakeup-source		- device can be used as a wakeup source.
+
+- interrupts		- interrupts used by the device.
+- interrupt-names	- "irq" and "wakeup" names are recognized by I2C core,
+			  other names are left to individual drivers.
+
+Binding may contain optional "interrupts" property, describing interrupts
+used by the device. I2C core will assign "irq" interrupt (or the very first
+interrupt if not using interrupt names) as primary interrupt for the slave.

+This document describes the generic device tree binding for MSI controllers and
+their master(s).
+
+Message Signaled Interrupts (MSIs) are a class of interrupts generated by a
+write to an MMIO address.
+
+MSIs were originally specified by PCI (and are used with PCIe), but may also be
+used with other busses, and hence a mechanism is required to relate devices on
+those busses to the MSI controllers which they are capable of using,
+potentially including additional information.
+
+MSIs are distinguished by some combination of:
+
+- The doorbell (the MMIO address written to).
+  
+  Devices may be configured by software to write to arbitrary doorbells which
+  they can address. An MSI controller may feature a number of doorbells.
+
+- The payload (the value written to the doorbell).
+  
+  Devices may be configured to write an arbitrary payload chosen by software.
+  MSI controllers may have restrictions on permitted payloads.
+
+- Sideband information accompanying the write.
+  
+  Typically this is neither configurable nor probeable, and depends on the path
+  taken through the memory system (i.e. it is a property of the combination of
+  MSI controller and device rather than a property of either in isolation).
+
+
+MSI controllers:
+================
+
+An MSI controller signals interrupts to a CPU when a write is made to an MMIO
+address by some master. An MSI controller may feature a number of doorbells.
+
+Required properties:
+--------------------
+
+- msi-controller: Identifies the node as an MSI controller.
+
+Optional properties:
+--------------------
+
+- #msi-cells: The number of cells in an msi-specifier, required if not zero.
+
+  Typically this will encode information related to sideband data, and will
+  not encode doorbells or payloads as these can be configured dynamically.
+
+  The meaning of the msi-specifier is defined by the device tree binding of
+  the specific MSI controller. 
+
+
+MSI clients
+===========
+
+MSI clients are devices which generate MSIs. For each MSI they wish to
+generate, the doorbell and payload may be configured, though sideband
+information may not be configurable.
+
+Required properties:
+--------------------
+
+- msi-parent: A list of phandle + msi-specifier pairs, one for each MSI
+  controller which the device is capable of using.
+
+  This property is unordered, and MSIs may be allocated from any combination of
+  MSI controllers listed in the msi-parent property.
+
+  If a device has restrictions on the allocation of MSIs, these restrictions
+  must be described with additional properties.
+
+  When #msi-cells is non-zero, busses with an msi-parent will require
+  additional properties to describe the relationship between devices on the bus
+  and the set of MSIs they can potentially generate.
+
+
+Example
+=======
+
+/ {
+	#address-cells = <1>;
+	#size-cells = <1>;
+
+	msi_a: msi-controller@a {
+		reg = <0xa 0xf00>;

+STMicroelectronics STi c8sectpfe binding
+============================================
+
+This document describes the c8sectpfe device bindings that is used to get transport
+stream data into the SoC on the TS pins, and into DDR for further processing.
+
+It is typically used in conjunction with one or more demodulator and tuner devices
+which converts from the RF to digital domain. Demodulators and tuners are usually
+located on an external DVB frontend card connected to SoC TS input pins.
+
+Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
+
+Required properties (controller (parent) node):
+- compatible	: Should be "stih407-c8sectpfe"
+
+- reg		: Address and length of register sets for each device in
+		  "reg-names"
+
+- reg-names	: The names of the register addresses corresponding to the
+		  registers filled in "reg":
+			- c8sectpfe: c8sectpfe registers
+			- c8sectpfe-ram: c8sectpfe internal sram
+
+- clocks	: phandle list of c8sectpfe clocks
+- clock-names	: should be "c8sectpfe"
+See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- pinctrl-names	: a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
+		   must be defined for each tsin child node.
+- pinctrl-0	: phandle referencing pin configuration for this tsin configuration
+See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+
+Required properties (tsin (child) node):
+
+- tsin-num	: tsin id of the InputBlock (must be between 0 to 6)
+- i2c-bus	: phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
+- rst-gpio	: reset gpio for this tsin channel.
+
+Optional properties (tsin (child) node):
+
+- invert-ts-clk		: Bool property to control sense of ts input clock (data stored on falling edge of clk).
+- serial-not-parallel	: Bool property to configure input bus width (serial on ts_data<7>).
+- async-not-sync	: Bool property to control if data is received in asynchronous mode
+			   (all bits/bytes with ts_valid or ts_packet asserted are valid).
+
+- dvb-card		: Describes the NIM card connected to this tsin channel.
+

+
+======
+
+Required properties:
+
+- compatible : Should be "dlg,da9062".
+- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
+  modified to match the chip's OTP settings).
+- interrupt-parent : Specifies the reference to the interrupt controller for
+  the DA9062.
+- interrupts : IRQ line information.
+- interrupt-controller
+
+See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
+further information on IRQ bindings.
+
+Sub-nodes:
+
+- regulators : This node defines the settings for the LDOs and BUCKs. The
+  DA9062 regulators are bound using their names listed below:

+* NXP SPI Flash Interface (SPIFI)
+
+NXP SPIFI is a specialized SPI interface for serial Flash devices.
+It supports one Flash device with 1-, 2- and 4-bits width in SPI
+mode 0 or 3. The controller operates in either command or memory
+mode. In memory mode the Flash is accessible from the CPU as
+normal memory.
+
+Required properties:
+  - compatible : Should be "nxp,lpc1773-spifi"
+  - reg : the first contains the register location and length,
+          the second contains the memory mapping address and length
+  - reg-names: Should contain the reg names "spifi" and "flash"
+  - interrupts : Should contain the interrupt for the device
+  - clocks : The clocks needed by the SPIFI controller
+  - clock-names : Should contain the clock names "spifi" and "reg"
+
+Optional properties:
+ - resets : phandle + reset specifier
+
+The SPI Flash must be a child of the SPIFI node and must have a
+compatible property as specified in bindings/mtd/jedec,spi-nor.txt
+
+Optionally it can also contain the following properties.
+ - spi-cpol : Controller only supports mode 0 and 3 so either
+              both spi-cpol and spi-cpha should be present or
+              none of them
+ - spi-cpha : See above
+ - spi-rx-bus-width : Used to select how many pins that are used
+                      for input on the controller
+
+See bindings/spi/spi-bus.txt for more information.
+
+Example:
+spifi: spifi@40003000 {
+	compatible = "nxp,lpc1773-spifi";

+Generic OPP (Operating Performance Points) Bindings
+----------------------------------------------------
+
+Devices work at voltage-current-frequency combinations and some implementations
+have the liberty of choosing these. These combinations are called Operating
+Performance Points aka OPPs. This document defines bindings for these OPPs
+applicable across wide range of devices. For illustration purpose, this document
+uses CPU as a device.
+
+This document contain multiple versions of OPP binding and only one of them
+should be used per device.
+
+Binding 1: operating-points
+============================
+
+This binding only supports voltage-frequency pairs.
+
+Properties:
+- operating-points: An array of 2-tuples items, and each item consists
+  of frequency and voltage like <freq-kHz vol-uV>.
+	freq: clock frequency in kHz
+	vol: voltage in microvolt
+
+Examples:

+Devices supporting OPPs must set their "operating-points-v2" property with
+phandle to a OPP table in their DT node. The OPP core will use this phandle to
+find the operating points for the device.
+
+Devices may want to choose OPP tables at runtime and so can provide a list of
+phandles here. But only *one* of them should be chosen at runtime. This must be
+accompanied by a corresponding "operating-points-names" property, to uniquely
+identify the OPP tables.
+
+If required, this can be extended for SoC vendor specfic bindings. Such bindings
+should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
+and should have a compatible description like: "operating-points-v2-<vendor>".
+
+Optional properties:
+- operating-points-names: Names of OPP tables (required if multiple OPP
+  tables are present), to uniquely identify them. The same list must be present
+  for all the CPUs which are sharing clock/voltage rails and hence the OPP
+  tables.
+
+* OPP Table Node
+
+This describes the OPPs belonging to a device. This node can have following
+properties:
+
+Required properties:
+- compatible: Allow OPPs to express their compatibility. It should be:
+  "operating-points-v2".
+
+- OPP nodes: One or more OPP nodes describing voltage-current-frequency
+  combinations. Their name isn't significant but their phandle can be used to
+  reference an OPP.
+
+Optional properties:
+- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
+  switch their DVFS state together, i.e. they share clock/voltage/current lines.
+  Missing property means devices have independent clock/voltage/current lines,
+  but they share OPP tables.
+
+- status: Marks the OPP table enabled/disabled.
+
+
+* OPP Node
+
+This defines voltage-current-frequency combinations along with other related
+properties.
+
+Required properties:
+- opp-hz: Frequency in Hz, expressed as a 64-bit big-endian integer.
+
+Optional properties:
+- opp-microvolt: voltage in micro Volts.
+
+  A single regulator's voltage is specified with an array of size one or three.
+  Single entry is for target voltage and three entries are for <target min max>
+  voltages.
+
+  Entries for multiple regulators must be present in the same order as
+  regulators are specified in device's DT node.
+
+- opp-microamp: The maximum current drawn by the device in microamperes
+  considering system specific parameters (such as transients, process, aging,
+  maximum operating temperature range etc.) as necessary. This may be used to
+  set the most efficient regulator operating mode.
+
+  Should only be set if opp-microvolt is set for the OPP.
+
+  Entries for multiple regulators must be present in the same order as
+  regulators are specified in device's DT node. If this property isn't required
+  for few regulators, then this should be marked as zero for them. If it isn't
+  required for any regulator, then this property need not be present.
+
+- clock-latency-ns: Specifies the maximum possible transition latency (in
+  nanoseconds) for switching to this OPP from any other OPP.
+
+- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
+  available on some platforms, where the device can run over its operating
+  frequency for a short duration of time limited by the device's power, current
+  and thermal limits.
+
+- opp-suspend: Marks the OPP to be used during device suspend. Only one OPP in
+  the table should have this.
+
+- status: Marks the node enabled/disabled.

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+  size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+  second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+  for possible values.
+
+For example, the following is the bare minimum node:
+
+	pinctrl: pinctrl@f0000e20 {
+		compatible = "cnxt,cx92755-pinctrl";
+		reg = <0xf0000e20 0x100>;
+		gpio-controller;
+		#gpio-cells = <2>;
+	};
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+  configured by this node. The format of a pin name string is "GP_xy", where x
+  is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+  "gpio", "client_a", "client_b", "client_c"
+
+Example:
+	pinctrl: pinctrl@f0000e20 {
+		compatible = "cnxt,cx92755-pinctrl";
+		reg = <0xf0000e20 0x100>;
+
+		uart0_default: uart0_active {
+			data_signals {
+				pins = "GP_O0", "GP_O1";
+				function = "client_b";
+			};
+		};
+	};
+
+	uart0: uart@f0000740 {
+		compatible = "cnxt,cx92755-usart";
+		...
+		pinctrl-0 = <&uart0_default>;
+		pinctrl-names = "default";
+	};
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

-Generic OPP (Operating Performance Points) Bindings
-----------------------------------------------------
-
-Devices work at voltage-current-frequency combinations and some implementations
-have the liberty of choosing these. These combinations are called Operating
-Performance Points aka OPPs. This document defines bindings for these OPPs
-applicable across wide range of devices. For illustration purpose, this document
-uses CPU as a device.
-
-This document contain multiple versions of OPP binding and only one of them
-should be used per device.
-
-Binding 1: operating-points
-============================
-
-This binding only supports voltage-frequency pairs.
-
-Properties:
-- operating-points: An array of 2-tuples items, and each item consists
-  of frequency and voltage like <freq-kHz vol-uV>.
-	freq: clock frequency in kHz
-	vol: voltage in microvolt
-
-Examples:
-
-cpu@0 {
-	compatible = "arm,cortex-a9";
-	reg = <0>;
-	next-level-cache = <&L2>;
-	operating-points = <
-		/* kHz    uV */
-		792000  1100000
-		396000  950000
-		198000  850000
-	>;
-};
-
-
-Binding 2: operating-points-v2
-============================
-
-* Property: operating-points-v2
-
-Devices supporting OPPs must set their "operating-points-v2" property with
-phandle to a OPP table in their DT node. The OPP core will use this phandle to
-find the operating points for the device.
-
-Devices may want to choose OPP tables at runtime and so can provide a list of
-phandles here. But only *one* of them should be chosen at runtime. This must be
-accompanied by a corresponding "operating-points-names" property, to uniquely
-identify the OPP tables.
-
-If required, this can be extended for SoC vendor specfic bindings. Such bindings
-should be documented as Documentation/devicetree/bindings/power/<vendor>-opp.txt
-and should have a compatible description like: "operating-points-v2-<vendor>".
-
-Optional properties:
-- operating-points-names: Names of OPP tables (required if multiple OPP
-  tables are present), to uniquely identify them. The same list must be present
-  for all the CPUs which are sharing clock/voltage rails and hence the OPP
-  tables.
-
-* OPP Table Node
-
-This describes the OPPs belonging to a device. This node can have following
-properties:
-
-Required properties:
-- compatible: Allow OPPs to express their compatibility. It should be:
-  "operating-points-v2".
-
-- OPP nodes: One or more OPP nodes describing voltage-current-frequency
-  combinations. Their name isn't significant but their phandle can be used to
-  reference an OPP.
-
-Optional properties:
-- opp-shared: Indicates that device nodes using this OPP Table Node's phandle
-  switch their DVFS state together, i.e. they share clock/voltage/current lines.
-  Missing property means devices have independent clock/voltage/current lines,
-  but they share OPP tables.
-
-- status: Marks the OPP table enabled/disabled.
-
-
-* OPP Node
-
-This defines voltage-current-frequency combinations along with other related
-properties.
-
-Required properties:
-- opp-hz: Frequency in Hz
-
-Optional properties:
-- opp-microvolt: voltage in micro Volts.
-
-  A single regulator's voltage is specified with an array of size one or three.
-  Single entry is for target voltage and three entries are for <target min max>
-  voltages.
-
-  Entries for multiple regulators must be present in the same order as
-  regulators are specified in device's DT node.
-
-- opp-microamp: The maximum current drawn by the device in microamperes
-  considering system specific parameters (such as transients, process, aging,
-  maximum operating temperature range etc.) as necessary. This may be used to
-  set the most efficient regulator operating mode.
-
-  Should only be set if opp-microvolt is set for the OPP.
-
-  Entries for multiple regulators must be present in the same order as
-  regulators are specified in device's DT node. If this property isn't required
-  for few regulators, then this should be marked as zero for them. If it isn't
-  required for any regulator, then this property need not be present.
-
-- clock-latency-ns: Specifies the maximum possible transition latency (in
-  nanoseconds) for switching to this OPP from any other OPP.
-
-- turbo-mode: Marks the OPP to be used only for turbo modes. Turbo mode is
-  available on some platforms, where the device can run over its operating
-  frequency for a short duration of time limited by the device's power, current
-  and thermal limits.
-
-- opp-suspend: Marks the OPP to be used during device suspend. Only one OPP in
-  the table should have this.
-
-- status: Marks the node enabled/disabled.

+Binding for Maxim MAX77686 regulators
+
+This is a part of the device tree bindings of MAX77686 multi-function device.
+More information can be found in ../mfd/max77686.txt file.
+
+The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
+regulators that can be controlled over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Optional node:
+- voltage-regulators : The regulators of max77686 have to be instantiated
+  under subnode named "voltage-regulators" using the following format.
+
+	regulator_name {
+		regulator-compatible = LDOn/BUCKn
+		standard regulator constraints....
+	};
+	refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+  The regulator node's name should be initialized with a string
+to get matched with their hardware counterparts as follow:
+
+	-LDOn 	:	for LDOs, where n can lie in range 1 to 26.
+			example: LDO1, LDO2, LDO26.
+	-BUCKn 	:	for BUCKs, where n can lie in range 1 to 9.
+			example: BUCK1, BUCK5, BUCK9.
+
+  Regulators which can be turned off during system suspend:
+	-LDOn	:	2, 6-8, 10-12, 14-16,
+	-BUCKn	:	1-4.
+  Use standard regulator bindings for it ('regulator-off-in-suspend').
+
+  LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
+  control. To turn this feature on this property must be added to the regulator
+  sub-node:
+	- maxim,ena-gpios :	one GPIO specifier enable control (the gpio
+				flags are actually ignored and always
+				ACTIVE_HIGH is used)
+
+Example:

+Optional properties:
+- timeout-sec: watchdog timeout value (in seconds).

+- atmel,idle-halt: present if you want to stop the watchdog when the CPU is

+	CAUTION: This property should be used with care, it actually makes the
+	watchdog not counting when the CPU is in idle state, therefore the

+	if the CPU stop working while it is in idle state, which is probably
+	not what you want.

-Ext3 is the ext2 filesystem enhanced with journalling capabilities.
+Ext3 is the ext2 filesystem enhanced with journalling capabilities. The
+filesystem is a subset of ext4 filesystem so use ext4 driver for accessing
+ext3 filesystems.
 
-Options
-=======
-
-When mounting an ext3 filesystem, the following option are accepted:
-(*) == default
-
-ro			Mount filesystem read only. Note that ext3 will replay
-			the journal (and thus write to the partition) even when
-			mounted "read only". Mount options "ro,noload" can be
-			used to prevent writes to the filesystem.
-
-journal=update		Update the ext3 file system's journal to the current
-			format.
-
-journal=inum		When a journal already exists, this option is ignored.
-			Otherwise, it specifies the number of the inode which
-			will represent the ext3 file system's journal file.
-
-journal_path=path
-journal_dev=devnum	When the external journal device's major/minor numbers
-			have changed, these options allow the user to specify
-			the new journal location.  The journal device is
-			identified through either its new major/minor numbers
-			encoded in devnum, or via a path to the device.
-
-norecovery		Don't load the journal on mounting. Note that this forces
-noload			mount of inconsistent filesystem, which can lead to
-			various problems.
-
-data=journal		All data are committed into the journal prior to being
-			written into the main file system.
-
-data=ordered	(*)	All data are forced directly out to the main file
-			system prior to its metadata being committed to the
-			journal.
-
-data=writeback		Data ordering is not preserved, data may be written
-			into the main file system after its metadata has been
-			committed to the journal.
-
-commit=nrsec	(*)	Ext3 can be told to sync all its data and metadata
-			every 'nrsec' seconds. The default value is 5 seconds.
-			This means that if you lose your power, you will lose
-			as much as the latest 5 seconds of work (your
-			filesystem will not be damaged though, thanks to the
-			journaling).  This default value (or any low value)
-			will hurt performance, but it's good for data-safety.
-			Setting it to 0 will have the same effect as leaving
-			it at the default (5 seconds).
-			Setting it to very large values will improve
-			performance.
-
-barrier=<0|1(*)>	This enables/disables the use of write barriers in
-barrier	(*)		the jbd code.  barrier=0 disables, barrier=1 enables.
-nobarrier		This also requires an IO stack which can support
-			barriers, and if jbd gets an error on a barrier
-			write, it will disable again with a warning.
-			Write barriers enforce proper on-disk ordering
-			of journal commits, making volatile disk write caches
-			safe to use, at some performance penalty.  If
-			your disks are battery-backed in one way or another,
-			disabling barriers may safely improve performance.
-			The mount options "barrier" and "nobarrier" can
-			also be used to enable or disable barriers, for
-			consistency with other ext3 mount options.
-
-user_xattr		Enables Extended User Attributes.  Additionally, you
-			need to have extended attribute support enabled in the
-			kernel configuration (CONFIG_EXT3_FS_XATTR).  See the
-			attr(5) manual page and http://acl.bestbits.at/ to
-			learn more about extended attributes.
-
-nouser_xattr		Disables Extended User Attributes.
-
-acl			Enables POSIX Access Control Lists support.
-			Additionally, you need to have ACL support enabled in
-			the kernel configuration (CONFIG_EXT3_FS_POSIX_ACL).
-			See the acl(5) manual page and http://acl.bestbits.at/
-			for more information.
-
-noacl			This option disables POSIX Access Control List
-			support.
-
-reservation
-
-noreservation
-
-bsddf 		(*)	Make 'df' act like BSD.
-minixdf			Make 'df' act like Minix.
-
-check=none		Don't do extra checking of bitmaps on mount.
-nocheck
-
-debug			Extra debugging information is sent to syslog.
-
-errors=remount-ro	Remount the filesystem read-only on an error.
-errors=continue		Keep going on a filesystem error.
-errors=panic		Panic and halt the machine if an error occurs.
-			(These mount options override the errors behavior
-			specified in the superblock, which can be
-			configured using tune2fs.)
-
-data_err=ignore(*)	Just print an error message if an error occurs
-			in a file data buffer in ordered mode.
-data_err=abort		Abort the journal if an error occurs in a file
-			data buffer in ordered mode.
-
-grpid			Give objects the same group ID as their creator.
-bsdgroups
-
-nogrpid		(*)	New objects have the group ID of their creator.
-sysvgroups
-
-resgid=n		The group ID which may use the reserved blocks.
-
-resuid=n		The user ID which may use the reserved blocks.
-
-sb=n			Use alternate superblock at this location.
-
-quota			These options are ignored by the filesystem. They
-noquota			are used only by quota tools to recognize volumes
-grpquota		where quota should be turned on. See documentation
-usrquota		in the quota-tools package for more details
-			(http://sourceforge.net/projects/linuxquota).
-
-jqfmt=<quota type>	These options tell filesystem details about quota
-usrjquota=<file>	so that quota information can be properly updated
-grpjquota=<file>	during journal replay. They replace the above
-			quota options. See documentation in the quota-tools
-			package for more details
-			(http://sourceforge.net/projects/linuxquota).

-Specification
-=============
-Ext3 shares all disk implementation with the ext2 filesystem, and adds
-transactions capabilities to ext2.  Journaling is done by the Journaling Block
-Device layer.
-
-Journaling Block Device layer
------------------------------
-The Journaling Block Device layer (JBD) isn't ext3 specific.  It was designed
-to add journaling capabilities to a block device.  The ext3 filesystem code
-will inform the JBD of modifications it is performing (called a transaction).
-The journal supports the transactions start and stop, and in case of a crash,
-the journal can replay the transactions to quickly put the partition back into
-a consistent state.
-
-Handles represent a single atomic update to a filesystem.  JBD can handle an
-external journal on a block device.
-
-Data Mode
----------
-There are 3 different data modes:
-
-* writeback mode
-In data=writeback mode, ext3 does not journal data at all.  This mode provides
-a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
-mode - metadata journaling.  A crash+recovery can cause incorrect data to
-appear in files which were written shortly before the crash.  This mode will
-typically provide the best ext3 performance.
-
-* ordered mode
-In data=ordered mode, ext3 only officially journals metadata, but it logically
-groups metadata and data blocks into a single unit called a transaction.  When
-it's time to write the new metadata out to disk, the associated data blocks
-are written first.  In general, this mode performs slightly slower than
-writeback but significantly faster than journal mode.
-
-* journal mode
-data=journal mode provides full data and metadata journaling.  All new data is
-written to the journal first, and then to its final location.
-In the event of a crash, the journal can be replayed, bringing both data and
-metadata into a consistent state.  This mode is the slowest except when data
-needs to be read from and written to disk at the same time where it
-outperforms all other modes.
-
-Compatibility
--------------
-
-Ext2 partitions can be easily convert to ext3, with `tune2fs -j <dev>`.
-Ext3 is fully compatible with Ext2.  Ext3 partitions can easily be mounted as
-Ext2.
-
-
-External Tools
-==============
-See manual pages to learn more.
-
-tune2fs: 	create a ext3 journal on a ext2 partition with the -j flag.
-mke2fs: 	create a ext3 partition with the -j flag.
-debugfs: 	ext2 and ext3 file system debugger.
-ext2online:	online (mounted) ext2 and ext3 filesystem resizer

+The active-low property
+-----------------------
+
+As a driver should not have to care about the physical line level, all of the
+gpiod_set_value_xxx() or gpiod_set_array_value_xxx() functions operate with
+the *logical* value. With this they take the active-low property into account.
+This means that they check whether the GPIO is configured to be active-low,
+and if so, they manipulate the passed value before the physical line level is

+With this, all the gpiod_set_(array)_value_xxx() functions interpret the
+parameter "value" as "active" ("1") or "inactive" ("0"). The physical line
+level will be driven accordingly.
+
+As an example, if the active-low property for a dedicated GPIO is set, and the
+gpiod_set_(array)_value_xxx() passes "active" ("1"), the physical line level
+will be driven low.

+Subsystem drivers using GPIO
+============================
+
+Note that standard kernel drivers exist for common GPIO tasks and will provide
+the right in-kernel and userspace APIs/ABIs for the job, and that these
+drivers can quite easily interconnect with other kernel subsystems using
+hardware descriptions such as device tree or ACPI:
+
+- leds-gpio: drivers/leds/leds-gpio.c will handle LEDs connected to  GPIO
+  lines, giving you the LED sysfs interface
+
+- ledtrig-gpio: drivers/leds/trigger/ledtrig-gpio.c will provide a LED trigger,
+  i.e. a LED will turn on/off in response to a GPIO line going high or low
+  (and that LED may in turn use the leds-gpio as per above).
+
+- gpio-keys: drivers/input/keyboard/gpio_keys.c is used when your GPIO line
+  can generate interrupts in response to a key press. Also supports debounce.
+
+- gpio-keys-polled: drivers/input/keyboard/gpio_keys_polled.c is used when your
+  GPIO line cannot generate interrupts, so it needs to be periodically polled
+  by a timer.
+
+- gpio_mouse: drivers/input/mouse/gpio_mouse.c is used to provide a mouse with
+  up to three buttons by simply using GPIOs and no mouse port. You can cut the
+  mouse cable and connect the wires to GPIO lines or solder a mouse connector
+  to the lines for a more permanent solution of this type.
+
+- gpio-beeper: drivers/input/misc/gpio-beeper.c is used to provide a beep from
+  an external speaker connected to a GPIO line.
+
+- gpio-tilt-polled: drivers/input/misc/gpio_tilt_polled.c provides tilt
+  detection switches using GPIO, which is useful for your homebrewn pinball
+  machine if for nothing else. It can detect different tilt angles of the
+  monitored object.
+
+- extcon-gpio: drivers/extcon/extcon-gpio.c is used when you need to read an
+  external connector status, such as a headset line for an audio driver or an
+  HDMI connector. It will provide a better userspace sysfs interface than GPIO.
+
+- restart-gpio: drivers/power/gpio-restart.c is used to restart/reboot the
+  system by pulling a GPIO line and will register a restart handler so
+  userspace can issue the right system call to restart the system.
+
+- poweroff-gpio: drivers/power/gpio-poweroff.c is used to power the system down
+  by pulling a GPIO line and will register a pm_power_off() callback so that
+  userspace can issue the right system call to power down the system.
+
+- gpio-gate-clock: drivers/clk/clk-gpio-gate.c is used to control a gated clock
+  (off/on) that uses a GPIO, and integrated with the clock subsystem.
+
+- i2c-gpio: drivers/i2c/busses/i2c-gpio.c is used to drive an I2C bus
+  (two wires, SDA and SCL lines) by hammering (bitbang) two GPIO lines. It will
+  appear as any other I2C bus to the system and makes it possible to connect
+  drivers for the I2C devices on the bus like any other I2C bus driver.
+
+- spi_gpio: drivers/spi/spi-gpio.c is used to drive an SPI bus (variable number
+  of wires, atleast SCK and optionally MISO, MOSI and chip select lines) using
+  GPIO hammering (bitbang). It will appear as any other SPI bus on the system
+  and makes it possible to connect drivers for SPI devices on the bus like
+  any other SPI bus driver. For example any MMC/SD card can then be connected
+  to this SPI by using the mmc_spi host from the MMC/SD card subsystem.
+
+- w1-gpio: drivers/w1/masters/w1-gpio.c is used to drive a one-wire bus using
+  a GPIO line, integrating with the W1 subsystem and handling devices on
+  the bus like any other W1 device.
+

+  system, connected to a GPIO line (and optionally a GPIO alarm line),

+  not overheat.
+
+- gpio-regulator: drivers/regulator/gpio-regulator.c is used to control a
+  regulator providing a certain voltage by pulling a GPIO line, integrating
+  with the regulator subsystem and giving you all the right interfaces.
+
+- gpio-wdt: drivers/watchdog/gpio_wdt.c is used to provide a watchdog timer
+  that will periodically "ping" a hardware connected to a GPIO line by toggling
+  it from 1-to-0-to-1. If that hardware does not recieve its "ping"
+  periodically, it will reset the system.
+
+- gpio-nand: drivers/mtd/nand/gpio.c is used to connect a NAND flash chip to
+  a set of simple GPIO lines: RDY, NCE, ALE, CLE, NWP. It interacts with the
+  NAND flash MTD subsystem and provides chip access and partition parsing like
+  any other NAND driving hardware.
+
+Apart from this there are special GPIO drivers in subsystems like MMC/SD to
+read card detect and write protect GPIO lines, and in the TTY serial subsystem
+to emulate MCTRL (modem control) signals CTS/RTS by using two GPIO lines. The
+MTD NOR flash has add-ons for extra GPIO lines too, though the address bus is
+usually connected directly to the flash.
+
+Use those instead of talking directly to the GPIOs using sysfs; they integrate
+with kernel frameworks better than your userspace code could. Needless to say,
+just using the apropriate kernel drivers will simplify and speed up your
+embedded hacking in particular by providing ready-made components.

+Broadcom Starfighter 2 Ethernet switch driver
+=============================================
+
+Broadcom's Starfighter 2 Ethernet switch hardware block is commonly found and
+deployed in the following products:
+
+- xDSL gateways such as BCM63138
+- streaming/multimedia Set Top Box such as BCM7445
+- Cable Modem/residential gateways such as BCM7145/BCM3390
+
+The switch is typically deployed in a configuration involving between 5 to 13
+ports, offering a range of built-in and customizable interfaces:
+
+- single integrated Gigabit PHY
+- quad integrated Gigabit PHY
+- quad external Gigabit PHY w/ MDIO multiplexer
+- integrated MoCA PHY
+- several external MII/RevMII/GMII/RGMII interfaces
+
+The switch also supports specific congestion control features which allow MoCA
+fail-over not to lose packets during a MoCA role re-election, as well as out of
+band back-pressure to the host CPU network interface when downstream interfaces
+are connected at a lower speed.
+
+The switch hardware block is typically interfaced using MMIO accesses and
+contains a bunch of sub-blocks/registers:
+
+* SWITCH_CORE: common switch registers
+* SWITCH_REG: external interfaces switch register
+* SWITCH_MDIO: external MDIO bus controller (there is another one in SWITCH_CORE,
+  which is used for indirect PHY accesses)
+* SWITCH_INDIR_RW: 64-bits wide register helper block
+* SWITCH_INTRL2_0/1: Level-2 interrupt controllers
+* SWITCH_ACB: Admission control block
+* SWITCH_FCB: Fail-over control block
+
+Implementation details
+======================
+
+The driver is located in drivers/net/dsa/bcm_sf2.c and is implemented as a DSA
+driver; see Documentation/networking/dsa/dsa.txt for details on the subsytem
+and what it provides.
+
+The SF2 switch is configured to enable a Broadcom specific 4-bytes switch tag
+which gets inserted by the switch for every packet forwarded to the CPU
+interface, conversely, the CPU network interface should insert a similar tag for
+packets entering the CPU port. The tag format is described in
+net/dsa/tag_brcm.c.
+
+Overall, the SF2 driver is a fairly regular DSA driver; there are a few
+specifics covered below.
+
+Device Tree probing
+-------------------
+
+The DSA platform device driver is probed using a specific compatible string
+provided in net/dsa/dsa.c. The reason for that is because the DSA subsystem gets
+registered as a platform device driver currently. DSA will provide the needed
+device_node pointers which are then accessible by the switch driver setup
+function to setup resources such as register ranges and interrupts. This
+currently works very well because none of the of_* functions utilized by the
+driver require a struct device to be bound to a struct device_node, but things
+may change in the future.
+
+MDIO indirect accesses
+----------------------
+
+Due to a limitation in how Broadcom switches have been designed, external
+Broadcom switches connected to a SF2 require the use of the DSA slave MDIO bus
+in order to properly configure them. By default, the SF2 pseudo-PHY address, and
+an external switch pseudo-PHY address will both be snooping for incoming MDIO
+transactions, since they are at the same address (30), resulting in some kind of
+"double" programming. Using DSA, and setting ds->phys_mii_mask accordingly, we
+selectively divert reads and writes towards external Broadcom switches
+pseudo-PHY addresses. Newer revisions of the SF2 hardware have introduced a
+configurable pseudo-PHY address which circumvents the initial design limitation.
+
+Multimedia over CoAxial (MoCA) interfaces
+-----------------------------------------
+
+MoCA interfaces are fairly specific and require the use of a firmware blob which
+gets loaded onto the MoCA processor(s) for packet processing. The switch
+hardware contains logic which will assert/de-assert link states accordingly for
+the MoCA interface whenever the MoCA coaxial cable gets disconnected or the
+firmware gets reloaded. The SF2 driver relies on such events to properly set its
+MoCA interface carrier state and properly report this to the networking stack.
+
+The MoCA interfaces are supported using the PHY library's fixed PHY/emulated PHY
+device and the switch driver registers a fixed_link_update callback for such
+PHYs which reflects the link state obtained from the interrupt handler.
+
+
+Power Management
+----------------
+
+Whenever possible, the SF2 driver tries to minimize the overall switch power
+consumption by applying a combination of:
+
+- turning off internal buffers/memories
+- disabling packet processing logic
+- putting integrated PHYs in IDDQ/low-power
+- reducing the switch core clock based on the active port count
+- enabling and advertising EEE
+- turning off RGMII data processing logic when the link goes down
+
+Wake-on-LAN
+-----------
+
+Wake-on-LAN is currently implemented by utilizing the host processor Ethernet
+MAC controller wake-on logic. Whenever Wake-on-LAN is requested, an intersection
+between the user request and the supported host Ethernet interface WoL
+capabilities is done and the intersection result gets configured. During
+system-wide suspend/resume, only ports not participating in Wake-on-LAN are

+Distributed Switch Architecture
+===============================
+
+Introduction
+============
+
+This document describes the Distributed Switch Architecture (DSA) subsystem
+design principles, limitations, interactions with other subsystems, and how to
+develop drivers for this subsystem as well as a TODO for developers interested
+in joining the effort.
+
+Design principles
+=================
+
+The Distributed Switch Architecture is a subsystem which was primarily designed
+to support Marvell Ethernet switches (MV88E6xxx, a.k.a Linkstreet product line)
+using Linux, but has since evolved to support other vendors as well.
+
+The original philosophy behind this design was to be able to use unmodified
+Linux tools such as bridge, iproute2, ifconfig to work transparently whether
+they configured/queried a switch port network device or a regular network
+device.
+
+An Ethernet switch is typically comprised of multiple front-panel ports, and one
+or more CPU or management port. The DSA subsystem currently relies on the
+presence of a management port connected to an Ethernet controller capable of
+receiving Ethernet frames from the switch. This is a very common setup for all
+kinds of Ethernet switches found in Small Home and Office products: routers,
+gateways, or even top-of-the rack switches. This host Ethernet controller will
+be later referred to as "master" and "cpu" in DSA terminology and code.
+
+The D in DSA stands for Distributed, because the subsystem has been designed
+with the ability to configure and manage cascaded switches on top of each other
+using upstream and downstream Ethernet links between switches. These specific
+ports are referred to as "dsa" ports in DSA terminology and code. A collection
+of multiple switches connected to each other is called a "switch tree".
+
+For each front-panel port, DSA will create specialized network devices which are
+used as controlling and data-flowing endpoints for use by the Linux networking
+stack. These specialized network interfaces are referred to as "slave" network
+interfaces in DSA terminology and code.
+
+The ideal case for using DSA is when an Ethernet switch supports a "switch tag"
+which is a hardware feature making the switch insert a specific tag for each
+Ethernet frames it received to/from specific ports to help the management
+interface figure out:
+
+- what port is this frame coming from
+- what was the reason why this frame got forwarded
+- how to send CPU originated traffic to specific ports
+
+The subsystem does support switches not capable of inserting/stripping tags, but
+the features might be slightly limited in that case (traffic separation relies
+on Port-based VLAN IDs).
+
+Note that DSA does not currently create network interfaces for the "cpu" and
+"dsa" ports because:
+
+- the "cpu" port is the Ethernet switch facing side of the management
+  controller, and as such, would create a duplication of feature, since you
+  would get two interfaces for the same conduit: master netdev, and "cpu" netdev
+
+- the "dsa" port(s) are just conduits between two or more switches, and as such
+  cannot really be used as proper network interfaces either, only the
+  downstream, or the top-most upstream interface makes sense with that model
+
+Switch tagging protocols
+------------------------
+
+DSA currently supports 4 different tagging protocols, and a tag-less mode as
+well. The different protocols are implemented in:
+
+net/dsa/tag_trailer.c: Marvell's 4 trailer tag mode (legacy)
+net/dsa/tag_dsa.c: Marvell's original DSA tag
+net/dsa/tag_edsa.c: Marvell's enhanced DSA tag
+net/dsa/tag_brcm.c: Broadcom's 4 bytes tag
+
+The exact format of the tag protocol is vendor specific, but in general, they
+all contain something which:
+
+- identifies which port the Ethernet frame came from/should be sent to
+- provides a reason why this frame was forwarded to the management interface
+
+Master network devices
+----------------------
+
+Master network devices are regular, unmodified Linux network device drivers for
+the CPU/management Ethernet interface. Such a driver might occasionally need to
+know whether DSA is enabled (e.g.: to enable/disable specific offload features),
+but the DSA subsystem has been proven to work with industry standard drivers:
+e1000e, mv643xx_eth etc. without having to introduce modifications to these
+drivers. Such network devices are also often referred to as conduit network
+devices since they act as a pipe between the host processor and the hardware
+Ethernet switch.
+
+Networking stack hooks
+----------------------
+
+When a master netdev is used with DSA, a small hook is placed in in the
+networking stack is in order to have the DSA subsystem process the Ethernet
+switch specific tagging protocol. DSA accomplishes this by registering a
+specific (and fake) Ethernet type (later becoming skb->protocol) with the
+networking stack, this is also known as a ptype or packet_type. A typical
+Ethernet Frame receive sequence looks like this:
+
+Master network device (e.g.: e1000e):
+
+Receive interrupt fires:
+- receive function is invoked
+- basic packet processing is done: getting length, status etc.
+- packet is prepared to be processed by the Ethernet layer by calling
+  eth_type_trans
+
+net/ethernet/eth.c:
+
+eth_type_trans(skb, dev)
+	if (dev->dsa_ptr != NULL)
+		-> skb->protocol = ETH_P_XDSA
+
+drivers/net/ethernet/*:
+
+netif_receive_skb(skb)
+	-> iterate over registered packet_type
+		-> invoke handler for ETH_P_XDSA, calls dsa_switch_rcv()
+
+net/dsa/dsa.c:
+	-> dsa_switch_rcv()
+		-> invoke switch tag specific protocol handler in
+		   net/dsa/tag_*.c
+
+net/dsa/tag_*.c:
+	-> inspect and strip switch tag protocol to determine originating port
+	-> locate per-port network device
+	-> invoke eth_type_trans() with the DSA slave network device
+	-> invoked netif_receive_skb()
+
+Past this point, the DSA slave network devices get delivered regular Ethernet
+frames that can be processed by the networking stack.
+
+Slave network devices
+---------------------
+
+Slave network devices created by DSA are stacked on top of their master network
+device, each of these network interfaces will be responsible for being a
+controlling and data-flowing end-point for each front-panel port of the switch.
+These interfaces are specialized in order to:
+
+- insert/remove the switch tag protocol (if it exists) when sending traffic
+  to/from specific switch ports
+- query the switch for ethtool operations: statistics, link state,
+  Wake-on-LAN, register dumps...
+- external/internal PHY management: link, auto-negotiation etc.
+
+These slave network devices have custom net_device_ops and ethtool_ops function
+pointers which allow DSA to introduce a level of layering between the networking
+stack/ethtool, and the switch driver implementation.
+
+Upon frame transmission from these slave network devices, DSA will look up which
+switch tagging protocol is currently registered with these network devices, and
+invoke a specific transmit routine which takes care of adding the relevant
+switch tag in the Ethernet frames.
+
+These frames are then queued for transmission using the master network device
+ndo_start_xmit() function, since they contain the appropriate switch tag, the
+Ethernet switch will be able to process these incoming frames from the
+management interface and delivers these frames to the physical switch port.
+
+Graphical representation
+------------------------
+
+Summarized, this is basically how DSA looks like from a network device
+perspective:
+
+
+			|---------------------------
+			| CPU network device (eth0)|
+			----------------------------
+			| <tag added by switch     |
+			|                          |
+			|                          |
+			|        tag added by CPU> |
+		|--------------------------------------------|
+		| Switch driver				     |

+		| sw0p0 |  | sw0p1 |  | sw0p2 |
+		|-------|  |-------|  |-------|
+
+Slave MDIO bus
+--------------
+
+In order to be able to read to/from a switch PHY built into it, DSA creates a
+slave MDIO bus which allows a specific switch driver to divert and intercept
+MDIO reads/writes towards specific PHY addresses. In most MDIO-connected
+switches, these functions would utilize direct or indirect PHY addressing mode
+to return standard MII registers from the switch builtin PHYs, allowing the PHY
+library and/or to return link status, link partner pages, auto-negotiation
+results etc..
+
+For Ethernet switches which have both external and internal MDIO busses, the
+slave MII bus can be utilized to mux/demux MDIO reads and writes towards either
+internal or external MDIO devices this switch might be connected to: internal
+PHYs, external PHYs, or even external switches.
+
+Data structures
+---------------
+
+DSA data structures are defined in include/net/dsa.h as well as
+net/dsa/dsa_priv.h.
+
+dsa_chip_data: platform data configuration for a given switch device, this
+structure describes a switch device's parent device, its address, as well as
+various properties of its ports: names/labels, and finally a routing table
+indication (when cascading switches)
+
+dsa_platform_data: platform device configuration data which can reference a
+collection of dsa_chip_data structure if multiples switches are cascaded, the
+master network device this switch tree is attached to needs to be referenced
+
+dsa_switch_tree: structure assigned to the master network device under
+"dsa_ptr", this structure references a dsa_platform_data structure as well as
+the tagging protocol supported by the switch tree, and which receive/transmit
+function hooks should be invoked, information about the directly attached switch
+is also provided: CPU port. Finally, a collection of dsa_switch are referenced
+to address individual switches in the tree.
+
+dsa_switch: structure describing a switch device in the tree, referencing a
+dsa_switch_tree as a backpointer, slave network devices, master network device,
+and a reference to the backing dsa_switch_driver
+
+dsa_switch_driver: structure referencing function pointers, see below for a full
+description.
+
+Design limitations
+==================
+
+DSA is a platform device driver
+-------------------------------
+
+DSA is implemented as a DSA platform device driver which is convenient because
+it will register the entire DSA switch tree attached to a master network device
+in one-shot, facilitating the device creation and simplifying the device driver
+model a bit, this comes however with a number of limitations:
+
+- building DSA and its switch drivers as modules is currently not working
+- the device driver parenting does not necessarily reflect the original
+  bus/device the switch can be created from
+- supporting non-MDIO and non-MMIO (platform) switches is not possible
+
+Limits on the number of devices and ports
+-----------------------------------------
+
+DSA currently limits the number of maximum switches within a tree to 4
+(DSA_MAX_SWITCHES), and the number of ports per switch to 12 (DSA_MAX_PORTS).
+These limits could be extended to support larger configurations would this need
+arise.
+
+Lack of CPU/DSA network devices
+-------------------------------
+
+DSA does not currently create slave network devices for the CPU or DSA ports, as
+described before. This might be an issue in the following cases:
+
+- inability to fetch switch CPU port statistics counters using ethtool, which
+  can make it harder to debug MDIO switch connected using xMII interfaces
+
+- inability to configure the CPU port link parameters based on the Ethernet
+  controller capabilities attached to it: http://patchwork.ozlabs.org/patch/509806/
+
+- inability to configure specific VLAN IDs / trunking VLANs between switches
+  when using a cascaded setup
+
+Common pitfalls using DSA setups
+--------------------------------
+
+Once a master network device is configured to use DSA (dev->dsa_ptr becomes
+non-NULL), and the switch behind it expects a tagging protocol, this network
+interface can only exclusively be used as a conduit interface. Sending packets
+directly through this interface (e.g.: opening a socket using this interface)
+will not make us go through the switch tagging protocol transmit function, so
+the Ethernet switch on the other end, expecting a tag will typically drop this
+frame.
+
+Slave network devices check that the master network device is UP before allowing
+you to administratively bring UP these slave network devices. A common
+configuration mistake is forgetting to bring UP the master network device first.
+
+Interactions with other subsystems
+==================================
+
+DSA currently leverages the following subsystems:
+
+- MDIO/PHY library: drivers/net/phy/phy.c, mdio_bus.c
+- Switchdev: net/switchdev/*
+- Device Tree for various of_* functions
+- HWMON: drivers/hwmon/*
+
+MDIO/PHY library
+----------------
+
+Slave network devices exposed by DSA may or may not be interfacing with PHY
+devices (struct phy_device as defined in include/linux/phy.h), but the DSA
+subsystem deals with all possible combinations:
+
+- internal PHY devices, built into the Ethernet switch hardware
+- external PHY devices, connected via an internal or external MDIO bus
+- internal PHY devices, connected via an internal MDIO bus
+- special, non-autonegotiated or non MDIO-managed PHY devices: SFPs, MoCA; a.k.a
+  fixed PHYs
+
+The PHY configuration is done by the dsa_slave_phy_setup() function and the
+logic basically looks like this:
+
+- if Device Tree is used, the PHY device is looked up using the standard
+  "phy-handle" property, if found, this PHY device is created and registered
+  using of_phy_connect()
+
+- if Device Tree is used, and the PHY device is "fixed", that is, conforms to
+  the definition of a non-MDIO managed PHY as defined in
+  Documentation/devicetree/bindings/net/fixed-link.txt, the PHY is registered
+  and connected transparently using the special fixed MDIO bus driver
+
+- finally, if the PHY is built into the switch, as is very common with
+  standalone switch packages, the PHY is probed using the slave MII bus created
+  by DSA
+
+
+SWITCHDEV
+---------
+
+DSA directly utilizes SWITCHDEV when interfacing with the bridge layer, and
+more specifically with its VLAN filtering portion when configuring VLANs on top
+of per-port slave network devices. Since DSA primarily deals with
+MDIO-connected switches, although not exclusively, SWITCHDEV's
+prepare/abort/commit phases are often simplified into a prepare phase which
+checks whether the operation is supporte by the DSA switch driver, and a commit
+phase which applies the changes.
+
+As of today, the only SWITCHDEV objects supported by DSA are the FDB and VLAN
+objects.
+
+Device Tree
+-----------
+
+DSA features a standardized binding which is documented in
+Documentation/devicetree/bindings/net/dsa/dsa.txt. PHY/MDIO library helper
+functions such as of_get_phy_mode(), of_phy_connect() are also used to query
+per-port PHY specific details: interface connection, MDIO bus location etc..
+
+HWMON
+-----
+
+Some switch drivers feature internal temperature sensors which are exposed as
+regular HWMON devices in /sys/class/hwmon/.
+
+Driver development
+==================
+
+DSA switch drivers need to implement a dsa_switch_driver structure which will
+contain the various members described below.
+
+register_switch_driver() registers this dsa_switch_driver in its internal list
+of drivers to probe for. unregister_switch_driver() does the exact opposite.
+
+Unless requested differently by setting the priv_size member accordingly, DSA
+does not allocate any driver private context space.
+
+Switch configuration
+--------------------
+
+- priv_size: additional size needed by the switch driver for its private context
+
+- tag_protocol: this is to indicate what kind of tagging protocol is supported,
+  should be a valid value from the dsa_tag_protocol enum
+
+- probe: probe routine which will be invoked by the DSA platform device upon
+  registration to test for the presence/absence of a switch device. For MDIO
+  devices, it is recommended to issue a read towards internal registers using
+  the switch pseudo-PHY and return whether this is a supported device. For other
+  buses, return a non-NULL string
+
+- setup: setup function for the switch, this function is responsible for setting
+  up the dsa_switch_driver private structure with all it needs: register maps,
+  interrupts, mutexes, locks etc.. This function is also expected to properly
+  configure the switch to separate all network interfaces from each other, that
+  is, they should be isolated by the switch hardware itself, typically by creating
+  a Port-based VLAN ID for each port and allowing only the CPU port and the
+  specific port to be in the forwarding vector. Ports that are unused by the
+  platform should be disabled. Past this function, the switch is expected to be
+  fully configured and ready to serve any kind of request. It is recommended
+  to issue a software reset of the switch during this setup function in order to
+  avoid relying on what a previous software agent such as a bootloader/firmware
+  may have previously configured.
+
+- set_addr: Some switches require the programming of the management interface's
+  Ethernet MAC address, switch drivers can also disable ageing of MAC addresses
+  on the management interface and "hardcode"/"force" this MAC address for the
+  CPU/management interface as an optimization
+
+PHY devices and link management
+-------------------------------
+
+- get_phy_flags: Some switches are interfaced to various kinds of Ethernet PHYs,
+  if the PHY library PHY driver needs to know about information it cannot obtain
+  on its own (e.g.: coming from switch memory mapped registers), this function
+  should return a 32-bits bitmask of "flags", that is private between the switch
+  driver and the Ethernet PHY driver in drivers/net/phy/*.
+
+- phy_read: Function invoked by the DSA slave MDIO bus when attempting to read
+  the switch port MDIO registers. If unavailable, return 0xffff for each read.
+  For builtin switch Ethernet PHYs, this function should allow reading the link
+  status, auto-negotiation results, link partner pages etc..
+
+- phy_write: Function invoked by the DSA slave MDIO bus when attempting to write
+  to the switch port MDIO registers. If unavailable return a negative error
+  code.
+
+- poll_link: Function invoked by DSA to query the link state of the switch
+  builtin Ethernet PHYs, per port. This function is responsible for calling
+  netif_carrier_{on,off} when appropriate, and can be used to poll all ports in a
+  single call. Executes from workqueue context.
+
+- adjust_link: Function invoked by the PHY library when a slave network device
+  is attached to a PHY device. This function is responsible for appropriately
+  configuring the switch port link parameters: speed, duplex, pause based on
+  what the phy_device is providing.
+
+- fixed_link_update: Function invoked by the PHY library, and specifically by
+  the fixed PHY driver asking the switch driver for link parameters that could
+  not be auto-negotiated, or obtained by reading the PHY registers through MDIO.
+  This is particularly useful for specific kinds of hardware such as QSGMII,
+  MoCA or other kinds of non-MDIO managed PHYs where out of band link
+  information is obtained
+
+Ethtool operations
+------------------
+
+- get_strings: ethtool function used to query the driver's strings, will
+  typically return statistics strings, private flags strings etc.
+
+- get_ethtool_stats: ethtool function used to query per-port statistics and
+  return their values. DSA overlays slave network devices general statistics:
+  RX/TX counters from the network device, with switch driver specific statistics
+  per port
+
+- get_sset_count: ethtool function used to query the number of statistics items
+
+- get_wol: ethtool function used to obtain Wake-on-LAN settings per-port, this
+  function may, for certain implementations also query the master network device
+  Wake-on-LAN settings if this interface needs to participate in Wake-on-LAN
+
+- set_wol: ethtool function used to configure Wake-on-LAN settings per-port,
+  direct counterpart to set_wol with similar restrictions
+
+- set_eee: ethtool function which is used to configure a switch port EEE (Green
+  Ethernet) settings, can optionally invoke the PHY library to enable EEE at the
+  PHY level if relevant. This function should enable EEE at the switch port MAC
+  controller and data-processing logic
+
+- get_eee: ethtool function which is used to query a switch port EEE settings,
+  this function should return the EEE state of the switch port MAC controller
+  and data-processing logic as well as query the PHY for its currently configured
+  EEE settings
+
+- get_eeprom_len: ethtool function returning for a given switch the EEPROM
+  length/size in bytes
+
+- get_eeprom: ethtool function returning for a given switch the EEPROM contents
+
+- set_eeprom: ethtool function writing specified data to a given switch EEPROM
+
+- get_regs_len: ethtool function returning the register length for a given
+  switch
+
+- get_regs: ethtool function returning the Ethernet switch internal register
+  contents. This function might require user-land code in ethtool to
+  pretty-print register values and registers
+
+Power management
+----------------
+
+- suspend: function invoked by the DSA platform device when the system goes to
+  suspend, should quiesce all Ethernet switch activities, but keep ports
+  participating in Wake-on-LAN active as well as additional wake-up logic if
+  supported
+
+- resume: function invoked by the DSA platform device when the system resumes,
+  should resume all Ethernet switch activities and re-configure the switch to be
+  in a fully active state
+
+- port_enable: function invoked by the DSA slave network device ndo_open
+  function when a port is administratively brought up, this function should be
+  fully enabling a given switch port. DSA takes care of marking the port with
+  BR_STATE_BLOCKING if the port is a bridge member, or BR_STATE_FORWARDING if it
+  was not, and propagating these changes down to the hardware
+
+- port_disable: function invoked by the DSA slave network device ndo_close
+  function when a port is administratively brought down, this function should be
+  fully disabling a given switch port. DSA takes care of marking the port with
+  BR_STATE_DISABLED and propagating changes to the hardware if this port is
+  disabled while being a bridge member
+
+Hardware monitoring
+-------------------
+
+These callbacks are only available if CONFIG_NET_DSA_HWMON is enabled:
+
+- get_temp: this function queries the given switch for its temperature
+
+- get_temp_limit: this function returns the switch current maximum temperature
+  limit
+
+- set_temp_limit: this function configures the maximum temperature limit allowed
+
+- get_temp_alarm: this function returns the critical temperature threshold
+  returning an alarm notification
+
+See Documentation/hwmon/sysfs-interface for details.
+
+Bridge layer
+------------
+
+- port_join_bridge: bridge layer function invoked when a given switch port is
+  added to a bridge, this function should be doing the necessary at the switch
+  level to permit the joining port from being added to the relevant logical
+  domain for it to ingress/egress traffic with other members of the bridge. DSA
+  does nothing but calculate a bitmask of switch ports currently members of the
+  specified bridge being requested the join
+
+- port_leave_bridge: bridge layer function invoked when a given switch port is
+  removed from a bridge, this function should be doing the necessary at the
+  switch level to deny the leaving port from ingress/egress traffic from the
+  remaining bridge members. When the port leaves the bridge, it should be aged
+  out at the switch hardware for the switch to (re) learn MAC addresses behind
+  this port. DSA calculates the bitmask of ports still members of the bridge
+  being left
+
+- port_stp_update: bridge layer function invoked when a given switch port STP
+  state is computed by the bridge layer and should be propagated to switch
+  hardware to forward/block/learn traffic. The switch driver is responsible for
+  computing a STP state change based on current and asked parameters and perform
+  the relevant ageing based on the intersection results
+
+Bridge VLAN filtering
+---------------------
+
+- port_pvid_get: bridge layer function invoked when a Port-based VLAN ID is
+  queried for the given switch port
+
+- port_pvid_set: bridge layer function invoked when a Port-based VLAN ID needs
+  to be configured on the given switch port
+
+- port_vlan_add: bridge layer function invoked when a VLAN is configured
+  (tagged or untagged) for the given switch port
+
+- port_vlan_del: bridge layer function invoked when a VLAN is removed from the
+  given switch port
+
+- vlan_getnext: bridge layer function invoked to query the next configured VLAN
+  in the switch, i.e. returns the bitmaps of members and untagged ports
+
+- port_fdb_add: bridge layer function invoked when the bridge wants to install a
+  Forwarding Database entry, the switch hardware should be programmed with the
+  specified address in the specified VLAN Id in the forwarding database
+  associated with this VLAN ID
+
+Note: VLAN ID 0 corresponds to the port private database, which, in the context
+of DSA, would be the its port-based VLAN, used by the associated bridge device.
+
+- port_fdb_del: bridge layer function invoked when the bridge wants to remove a
+  Forwarding Database entry, the switch hardware should be programmed to delete
+  the specified MAC address from the specified VLAN ID if it was mapped into
+  this port forwarding database
+
+TODO
+====
+
+The platform device problem
+---------------------------
+DSA is currently implemented as a platform device driver which is far from ideal
+as was discussed in this thread:
+
+http://permalink.gmane.org/gmane.linux.network/329848
+
+This basically prevents the device driver model to be properly used and applied,
+and support non-MDIO, non-MMIO Ethernet connected switches.
+
+Another problem with the platform device driver approach is that it prevents the
+use of a modular switch drivers build due to a circular dependency, illustrated
+here:
+
+http://comments.gmane.org/gmane.linux.network/345803
+
+Attempts of reworking this has been done here:
+
+https://lwn.net/Articles/643149/
+
+Making SWITCHDEV and DSA converge towards an unified codebase
+-------------------------------------------------------------
+
+SWITCHDEV properly takes care of abstracting the networking stack with offload
+capable hardware, but does not enforce a strict switch device driver model. On
+the other DSA enforces a fairly strict device driver model, and deals with most
+of the switch specific. At some point we should envision a merger between these
+two subsystems and get the best of both worlds.
+
+Other hanging fruits
+--------------------
+
+- making the number of ports fully dynamic and not dependent on DSA_MAX_PORTS
+- allowing more than one CPU/management interface:
+  http://comments.gmane.org/gmane.linux.network/365657
+- porting more drivers from other vendors:
+  http://comments.gmane.org/gmane.linux.network/365510

+Introduction
+============
+
+    The IBM Power architecture provides support for CAPI (Coherent
+    Accelerator Power Interface), which is available to certain PCIe slots
+    on Power 8 systems. CAPI can be thought of as a special tunneling
+    protocol through PCIe that allow PCIe adapters to look like special
+    purpose co-processors which can read or write an application's
+    memory and generate page faults. As a result, the host interface to
+    an adapter running in CAPI mode does not require the data buffers to
+    be mapped to the device's memory (IOMMU bypass) nor does it require
+    memory to be pinned.
+
+    On Linux, Coherent Accelerator (CXL) kernel services present CAPI
+    devices as a PCI device by implementing a virtual PCI host bridge.
+    This abstraction simplifies the infrastructure and programming
+    model, allowing for drivers to look similar to other native PCI
+    device drivers.
+
+    CXL provides a mechanism by which user space applications can
+    directly talk to a device (network or storage) bypassing the typical
+    kernel/device driver stack. The CXL Flash Adapter Driver enables a
+    user space application direct access to Flash storage.
+
+    The CXL Flash Adapter Driver is a kernel module that sits in the
+    SCSI stack as a low level device driver (below the SCSI disk and
+    protocol drivers) for the IBM CXL Flash Adapter. This driver is
+    responsible for the initialization of the adapter, setting up the
+    special path for user space access, and performing error recovery. It
+    communicates directly the Flash Accelerator Functional Unit (AFU)
+    as described in Documentation/powerpc/cxl.txt.
+
+    The cxlflash driver supports two, mutually exclusive, modes of
+    operation at the device (LUN) level:
+
+        - Any flash device (LUN) can be configured to be accessed as a
+          regular disk device (i.e.: /dev/sdc). This is the default mode.
+
+        - Any flash device (LUN) can be configured to be accessed from
+          user space with a special block library. This mode further
+          specifies the means of accessing the device and provides for
+          either raw access to the entire LUN (referred to as direct
+          or physical LUN access) or access to a kernel/AFU-mediated
+          partition of the LUN (referred to as virtual LUN access). The
+          segmentation of a disk device into virtual LUNs is assisted
+          by special translation services provided by the Flash AFU.
+
+Overview
+========
+
+    The Coherent Accelerator Interface Architecture (CAIA) introduces a
+    concept of a master context. A master typically has special privileges
+    granted to it by the kernel or hypervisor allowing it to perform AFU
+    wide management and control. The master may or may not be involved
+    directly in each user I/O, but at the minimum is involved in the
+    initial setup before the user application is allowed to send requests
+    directly to the AFU.
+
+    The CXL Flash Adapter Driver establishes a master context with the
+    AFU. It uses memory mapped I/O (MMIO) for this control and setup. The
+    Adapter Problem Space Memory Map looks like this:
+
+                     +-------------------------------+
+                     |    512 * 64 KB User MMIO      |
+                     |        (per context)          |
+                     |       User Accessible         |
+                     +-------------------------------+
+                     |    512 * 128 B per context    |
+                     |    Provisioning and Control   |
+                     |   Trusted Process accessible  |
+                     +-------------------------------+
+                     |         64 KB Global          |
+                     |   Trusted Process accessible  |
+                     +-------------------------------+
+
+    This driver configures itself into the SCSI software stack as an
+    adapter driver. The driver is the only entity that is considered a
+    Trusted Process to program the Provisioning and Control and Global
+    areas in the MMIO Space shown above.  The master context driver
+    discovers all LUNs attached to the CXL Flash adapter and instantiates
+    scsi block devices (/dev/sdb, /dev/sdc etc.) for each unique LUN
+    seen from each path.
+
+    Once these scsi block devices are instantiated, an application
+    written to a specification provided by the block library may get
+    access to the Flash from user space (without requiring a system call).
+
+    This master context driver also provides a series of ioctls for this
+    block library to enable this user space access.  The driver supports
+    two modes for accessing the block device.
+
+    The first mode is called a virtual mode. In this mode a single scsi
+    block device (/dev/sdb) may be carved up into any number of distinct
+    virtual LUNs. The virtual LUNs may be resized as long as the sum of
+    the sizes of all the virtual LUNs, along with the meta-data associated
+    with it does not exceed the physical capacity.
+
+    The second mode is called the physical mode. In this mode a single
+    block device (/dev/sdb) may be opened directly by the block library
+    and the entire space for the LUN is available to the application.
+
+    Only the physical mode provides persistence of the data.  i.e. The
+    data written to the block device will survive application exit and
+    restart and also reboot. The virtual LUNs do not persist (i.e. do
+    not survive after the application terminates or the system reboots).
+
+
+Block library API
+=================
+
+    Applications intending to get access to the CXL Flash from user
+    space should use the block library, as it abstracts the details of
+    interfacing directly with the cxlflash driver that are necessary for
+    performing administrative actions (i.e.: setup, tear down, resize).
+    The block library can be thought of as a 'user' of services,
+    implemented as IOCTLs, that are provided by the cxlflash driver
+    specifically for devices (LUNs) operating in user space access
+    mode. While it is not a requirement that applications understand
+    the interface between the block library and the cxlflash driver,
+    a high-level overview of each supported service (IOCTL) is provided
+    below.
+
+    The block library can be found on GitHub:
+    http://www.github.com/mikehollinger/ibmcapikv
+
+
+CXL Flash Driver IOCTLs
+=======================
+
+    Users, such as the block library, that wish to interface with a flash
+    device (LUN) via user space access need to use the services provided
+    by the cxlflash driver. As these services are implemented as ioctls,
+    a file descriptor handle must first be obtained in order to establish
+    the communication channel between a user and the kernel.  This file
+    descriptor is obtained by opening the device special file associated
+    with the scsi disk device (/dev/sdb) that was created during LUN
+    discovery. As per the location of the cxlflash driver within the
+    SCSI protocol stack, this open is actually not seen by the cxlflash
+    driver. Upon successful open, the user receives a file descriptor
+    (herein referred to as fd1) that should be used for issuing the
+    subsequent ioctls listed below.
+
+    The structure definitions for these IOCTLs are available in:
+    uapi/scsi/cxlflash_ioctl.h
+
+DK_CXLFLASH_ATTACH
+------------------
+
+    This ioctl obtains, initializes, and starts a context using the CXL
+    kernel services. These services specify a context id (u16) by which
+    to uniquely identify the context and its allocated resources. The
+    services additionally provide a second file descriptor (herein
+    referred to as fd2) that is used by the block library to initiate
+    memory mapped I/O (via mmap()) to the CXL flash device and poll for
+    completion events. This file descriptor is intentionally installed by
+    this driver and not the CXL kernel services to allow for intermediary
+    notification and access in the event of a non-user-initiated close(),
+    such as a killed process. This design point is described in further
+    detail in the description for the DK_CXLFLASH_DETACH ioctl.
+
+    There are a few important aspects regarding the "tokens" (context id
+    and fd2) that are provided back to the user:
+
+        - These tokens are only valid for the process under which they
+          were created. The child of a forked process cannot continue
+          to use the context id or file descriptor created by its parent
+          (see DK_CXLFLASH_VLUN_CLONE for further details).
+
+        - These tokens are only valid for the lifetime of the context and
+          the process under which they were created. Once either is
+          destroyed, the tokens are to be considered stale and subsequent
+          usage will result in errors.
+
+        - When a context is no longer needed, the user shall detach from
+          the context via the DK_CXLFLASH_DETACH ioctl.
+
+        - A close on fd2 will invalidate the tokens. This operation is not
+          required by the user.
+
+DK_CXLFLASH_USER_DIRECT
+-----------------------
+    This ioctl is responsible for transitioning the LUN to direct
+    (physical) mode access and configuring the AFU for direct access from
+    user space on a per-context basis. Additionally, the block size and
+    last logical block address (LBA) are returned to the user.
+
+    As mentioned previously, when operating in user space access mode,
+    LUNs may be accessed in whole or in part. Only one mode is allowed
+    at a time and if one mode is active (outstanding references exist),
+    requests to use the LUN in a different mode are denied.
+
+    The AFU is configured for direct access from user space by adding an
+    entry to the AFU's resource handle table. The index of the entry is
+    treated as a resource handle that is returned to the user. The user
+    is then able to use the handle to reference the LUN during I/O.
+
+DK_CXLFLASH_USER_VIRTUAL
+------------------------
+    This ioctl is responsible for transitioning the LUN to virtual mode
+    of access and configuring the AFU for virtual access from user space
+    on a per-context basis. Additionally, the block size and last logical
+    block address (LBA) are returned to the user.
+
+    As mentioned previously, when operating in user space access mode,
+    LUNs may be accessed in whole or in part. Only one mode is allowed
+    at a time and if one mode is active (outstanding references exist),
+    requests to use the LUN in a different mode are denied.
+
+    The AFU is configured for virtual access from user space by adding
+    an entry to the AFU's resource handle table. The index of the entry
+    is treated as a resource handle that is returned to the user. The
+    user is then able to use the handle to reference the LUN during I/O.
+
+    By default, the virtual LUN is created with a size of 0. The user
+    would need to use the DK_CXLFLASH_VLUN_RESIZE ioctl to adjust the grow
+    the virtual LUN to a desired size. To avoid having to perform this
+    resize for the initial creation of the virtual LUN, the user has the
+    option of specifying a size as part of the DK_CXLFLASH_USER_VIRTUAL
+    ioctl, such that when success is returned to the user, the
+    resource handle that is provided is already referencing provisioned
+    storage. This is reflected by the last LBA being a non-zero value.
+
+DK_CXLFLASH_VLUN_RESIZE
+-----------------------
+    This ioctl is responsible for resizing a previously created virtual
+    LUN and will fail if invoked upon a LUN that is not in virtual
+    mode. Upon success, an updated last LBA is returned to the user
+    indicating the new size of the virtual LUN associated with the
+    resource handle.
+
+    The partitioning of virtual LUNs is jointly mediated by the cxlflash
+    driver and the AFU. An allocation table is kept for each LUN that is
+    operating in the virtual mode and used to program a LUN translation
+    table that the AFU references when provided with a resource handle.
+
+DK_CXLFLASH_RELEASE
+-------------------
+    This ioctl is responsible for releasing a previously obtained
+    reference to either a physical or virtual LUN. This can be
+    thought of as the inverse of the DK_CXLFLASH_USER_DIRECT or
+    DK_CXLFLASH_USER_VIRTUAL ioctls. Upon success, the resource handle
+    is no longer valid and the entry in the resource handle table is
+    made available to be used again.
+
+    As part of the release process for virtual LUNs, the virtual LUN
+    is first resized to 0 to clear out and free the translation tables
+    associated with the virtual LUN reference.
+
+DK_CXLFLASH_DETACH
+------------------
+    This ioctl is responsible for unregistering a context with the
+    cxlflash driver and release outstanding resources that were
+    not explicitly released via the DK_CXLFLASH_RELEASE ioctl. Upon
+    success, all "tokens" which had been provided to the user from the
+    DK_CXLFLASH_ATTACH onward are no longer valid.
+
+DK_CXLFLASH_VLUN_CLONE
+----------------------
+    This ioctl is responsible for cloning a previously created
+    context to a more recently created context. It exists solely to
+    support maintaining user space access to storage after a process
+    forks. Upon success, the child process (which invoked the ioctl)
+    will have access to the same LUNs via the same resource handle(s)
+    and fd2 as the parent, but under a different context.
+
+    Context sharing across processes is not supported with CXL and
+    therefore each fork must be met with establishing a new context
+    for the child process. This ioctl simplifies the state management
+    and playback required by a user in such a scenario. When a process
+    forks, child process can clone the parents context by first creating
+    a context (via DK_CXLFLASH_ATTACH) and then using this ioctl to
+    perform the clone from the parent to the child.
+
+    The clone itself is fairly simple. The resource handle and lun
+    translation tables are copied from the parent context to the child's
+    and then synced with the AFU.
+
+DK_CXLFLASH_VERIFY
+------------------
+    This ioctl is used to detect various changes such as the capacity of
+    the disk changing, the number of LUNs visible changing, etc. In cases
+    where the changes affect the application (such as a LUN resize), the
+    cxlflash driver will report the changed state to the application.
+
+    The user calls in when they want to validate that a LUN hasn't been
+    changed in response to a check condition. As the user is operating out
+    of band from the kernel, they will see these types of events without
+    the kernel's knowledge. When encountered, the user's architected
+    behavior is to call in to this ioctl, indicating what they want to
+    verify and passing along any appropriate information. For now, only
+    verifying a LUN change (ie: size different) with sense data is
+    supported.
+
+DK_CXLFLASH_RECOVER_AFU
+-----------------------
+    This ioctl is used to drive recovery (if such an action is warranted)
+    of a specified user context. Any state associated with the user context
+    is re-established upon successful recovery.
+
+    User contexts are put into an error condition when the device needs to
+    be reset or is terminating. Users are notified of this error condition
+    by seeing all 0xF's on an MMIO read. Upon encountering this, the
+    architected behavior for a user is to call into this ioctl to recover
+    their context. A user may also call into this ioctl at any time to
+    check if the device is operating normally. If a failure is returned
+    from this ioctl, the user is expected to gracefully clean up their
+    context via release/detach ioctls. Until they do, the context they
+    hold is not relinquished. The user may also optionally exit the process
+    at which time the context/resources they held will be freed as part of
+    the release fop.
+
+DK_CXLFLASH_MANAGE_LUN
+----------------------
+    This ioctl is used to switch a LUN from a mode where it is available
+    for file-system access (legacy), to a mode where it is set aside for
+    exclusive user space access (superpipe). In case a LUN is visible
+    across multiple ports and adapters, this ioctl is used to uniquely
+    identify each LUN by its World Wide Node Name (WWNN).

+MOTIVATION
+
+The idle page tracking feature allows to track which memory pages are being
+accessed by a workload and which are idle. This information can be useful for
+estimating the workload's working set size, which, in turn, can be taken into
+account when configuring the workload parameters, setting memory cgroup limits,
+or deciding where to place the workload within a compute cluster.
+
+It is enabled by CONFIG_IDLE_PAGE_TRACKING=y.
+
+USER API
+
+The idle page tracking API is located at /sys/kernel/mm/page_idle. Currently,
+it consists of the only read-write file, /sys/kernel/mm/page_idle/bitmap.
+
+The file implements a bitmap where each bit corresponds to a memory page. The
+bitmap is represented by an array of 8-byte integers, and the page at PFN #i is
+mapped to bit #i%64 of array element #i/64, byte order is native. When a bit is
+set, the corresponding page is idle.
+
+A page is considered idle if it has not been accessed since it was marked idle
+(for more details on what "accessed" actually means see the IMPLEMENTATION
+DETAILS section). To mark a page idle one has to set the bit corresponding to
+the page by writing to the file. A value written to the file is OR-ed with the
+current bitmap value.
+
+Only accesses to user memory pages are tracked. These are pages mapped to a
+process address space, page cache and buffer pages, swap cache pages. For other
+page types (e.g. SLAB pages) an attempt to mark a page idle is silently ignored,
+and hence such pages are never reported idle.
+
+For huge pages the idle flag is set only on the head page, so one has to read
+/proc/kpageflags in order to correctly count idle huge pages.
+
+Reading from or writing to /sys/kernel/mm/page_idle/bitmap will return
+-EINVAL if you are not starting the read/write on an 8-byte boundary, or
+if the size of the read/write is not a multiple of 8 bytes. Writing to
+this file beyond max PFN will return -ENXIO.
+
+That said, in order to estimate the amount of pages that are not used by a
+workload one should:
+
+ 1. Mark all the workload's pages as idle by setting corresponding bits in
+    /sys/kernel/mm/page_idle/bitmap. The pages can be found by reading
+    /proc/pid/pagemap if the workload is represented by a process, or by
+    filtering out alien pages using /proc/kpagecgroup in case the workload is
+    placed in a memory cgroup.
+
+ 2. Wait until the workload accesses its working set.
+
+ 3. Read /sys/kernel/mm/page_idle/bitmap and count the number of bits set. If
+    one wants to ignore certain types of pages, e.g. mlocked pages since they
+    are not reclaimable, he or she can filter them out using /proc/kpageflags.
+
+See Documentation/vm/pagemap.txt for more information about /proc/pid/pagemap,
+/proc/kpageflags, and /proc/kpagecgroup.
+
+IMPLEMENTATION DETAILS
+
+The kernel internally keeps track of accesses to user memory pages in order to
+reclaim unreferenced pages first on memory shortage conditions. A page is
+considered referenced if it has been recently accessed via a process address
+space, in which case one or more PTEs it is mapped to will have the Accessed bit
+set, or marked accessed explicitly by the kernel (see mark_page_accessed()). The
+latter happens when:
+
+ - a userspace process reads or writes a page using a system call (e.g. read(2)
+   or write(2))
+
+ - a page that is used for storing filesystem buffers is read or written,
+   because a process needs filesystem metadata stored in it (e.g. lists a
+   directory tree)
+
+ - a page is accessed by a device driver using get_user_pages()
+
+When a dirty page is written to swap or disk as a result of memory reclaim or
+exceeding the dirty memory limit, it is not marked referenced.
+
+The idle memory tracking feature adds a new page flag, the Idle flag. This flag
+is set manually, by writing to /sys/kernel/mm/page_idle/bitmap (see the USER API
+section), and cleared automatically whenever a page is referenced as defined
+above.
+
+When a page is marked idle, the Accessed bit must be cleared in all PTEs it is
+mapped to, otherwise we will not be able to detect accesses to the page coming
+from a process address space. To avoid interference with the reclaimer, which,
+as noted above, uses the Accessed bit to promote actively referenced pages, one
+more page flag is introduced, the Young flag. When the PTE Accessed bit is
+cleared as a result of setting or updating a page's Idle flag, the Young flag
+is set on the page. The reclaimer treats the Young flag as an extra PTE
+Accessed bit and therefore will consider such a page as referenced.
+
+Since the idle memory tracking feature is based on the memory reclaimer logic,
+it only works with pages that are on an LRU list, other pages are silently
+ignored. That means it will ignore a user memory page if it is isolated, but
+since there are usually not many of them, it should not affect the overall
+result noticeably. In order not to stall scanning of the idle page bitmap,
+locked pages may be skipped too.

+= Userfaultfd =
+
+== Objective ==
+
+Userfaults allow the implementation of on-demand paging from userland
+and more generally they allow userland to take control of various
+memory page faults, something otherwise only the kernel code could do.
+
+For example userfaults allows a proper and more optimal implementation
+of the PROT_NONE+SIGSEGV trick.
+
+== Design ==
+
+Userfaults are delivered and resolved through the userfaultfd syscall.
+
+The userfaultfd (aside from registering and unregistering virtual
+memory ranges) provides two primary functionalities:
+
+1) read/POLLIN protocol to notify a userland thread of the faults
+   happening
+
+2) various UFFDIO_* ioctls that can manage the virtual memory regions
+   registered in the userfaultfd that allows userland to efficiently
+   resolve the userfaults it receives via 1) or to manage the virtual
+   memory in the background
+
+The real advantage of userfaults if compared to regular virtual memory
+management of mremap/mprotect is that the userfaults in all their
+operations never involve heavyweight structures like vmas (in fact the
+userfaultfd runtime load never takes the mmap_sem for writing).
+
+Vmas are not suitable for page- (or hugepage) granular fault tracking
+when dealing with virtual address spaces that could span
+Terabytes. Too many vmas would be needed for that.
+
+The userfaultfd once opened by invoking the syscall, can also be
+passed using unix domain sockets to a manager process, so the same
+manager process could handle the userfaults of a multitude of
+different processes without them being aware about what is going on
+(well of course unless they later try to use the userfaultfd
+themselves on the same region the manager is already tracking, which
+is a corner case that would currently return -EBUSY).
+
+== API ==
+
+When first opened the userfaultfd must be enabled invoking the
+UFFDIO_API ioctl specifying a uffdio_api.api value set to UFFD_API (or
+a later API version) which will specify the read/POLLIN protocol
+userland intends to speak on the UFFD and the uffdio_api.features
+userland requires. The UFFDIO_API ioctl if successful (i.e. if the
+requested uffdio_api.api is spoken also by the running kernel and the
+requested features are going to be enabled) will return into
+uffdio_api.features and uffdio_api.ioctls two 64bit bitmasks of
+respectively all the available features of the read(2) protocol and
+the generic ioctl available.
+
+Once the userfaultfd has been enabled the UFFDIO_REGISTER ioctl should
+be invoked (if present in the returned uffdio_api.ioctls bitmask) to
+register a memory range in the userfaultfd by setting the
+uffdio_register structure accordingly. The uffdio_register.mode
+bitmask will specify to the kernel which kind of faults to track for
+the range (UFFDIO_REGISTER_MODE_MISSING would track missing
+pages). The UFFDIO_REGISTER ioctl will return the
+uffdio_register.ioctls bitmask of ioctls that are suitable to resolve
+userfaults on the range registered. Not all ioctls will necessarily be
+supported for all memory types depending on the underlying virtual
+memory backend (anonymous memory vs tmpfs vs real filebacked
+mappings).
+
+Userland can use the uffdio_register.ioctls to manage the virtual
+address space in the background (to add or potentially also remove
+memory from the userfaultfd registered range). This means a userfault
+could be triggering just before userland maps in the background the
+user-faulted page.
+
+The primary ioctl to resolve userfaults is UFFDIO_COPY. That
+atomically copies a page into the userfault registered range and wakes
+up the blocked userfaults (unless uffdio_copy.mode &
+UFFDIO_COPY_MODE_DONTWAKE is set). Other ioctl works similarly to
+UFFDIO_COPY. They're atomic as in guaranteeing that nothing can see an
+half copied page since it'll keep userfaulting until the copy has
+finished.
+
+== QEMU/KVM ==
+
+QEMU/KVM is using the userfaultfd syscall to implement postcopy live
+migration. Postcopy live migration is one form of memory
+externalization consisting of a virtual machine running with part or
+all of its memory residing on a different node in the cloud. The
+userfaultfd abstraction is generic enough that not a single line of
+KVM kernel code had to be modified in order to add postcopy live
+migration to QEMU.
+
+Guest async page faults, FOLL_NOWAIT and all other GUP features work
+just fine in combination with userfaults. Userfaults trigger async
+page faults in the guest scheduler so those guest processes that
+aren't waiting for userfaults (i.e. network bound) can keep running in
+the guest vcpus.
+
+It is generally beneficial to run one pass of precopy live migration
+just before starting postcopy live migration, in order to avoid
+generating userfaults for readonly guest regions.
+
+The implementation of postcopy live migration currently uses one
+single bidirectional socket but in the future two different sockets
+will be used (to reduce the latency of the userfaults to the minimum
+possible without having to decrease /proc/sys/net/ipv4/tcp_wmem).
+
+The QEMU in the source node writes all pages that it knows are missing
+in the destination node, into the socket, and the migration thread of
+the QEMU running in the destination node runs UFFDIO_COPY|ZEROPAGE
+ioctls on the userfaultfd in order to map the received pages into the
+guest (UFFDIO_ZEROCOPY is used if the source page was a zero page).
+
+A different postcopy thread in the destination node listens with
+poll() to the userfaultfd in parallel. When a POLLIN event is
+generated after a userfault triggers, the postcopy thread read() from
+the userfaultfd and receives the fault address (or -EAGAIN in case the
+userfault was already resolved and waken by a UFFDIO_COPY|ZEROPAGE run
+by the parallel QEMU migration thread).
+
+After the QEMU postcopy thread (running in the destination node) gets
+the userfault address it writes the information about the missing page
+into the socket. The QEMU source node receives the information and
+roughly "seeks" to that page address and continues sending all
+remaining missing pages from that new page offset. Soon after that
+(just the time to flush the tcp_wmem queue through the network) the
+migration thread in the QEMU running in the destination node will
+receive the page that triggered the userfault and it'll map it as
+usual with the UFFDIO_COPY|ZEROPAGE (without actually knowing if it
+was spontaneously sent by the source or if it was an urgent page
+requested through an userfault).
+
+By the time the userfaults start, the QEMU in the destination node
+doesn't need to keep any per-page state bitmap relative to the live
+migration around and a single per-page bitmap has to be maintained in
+the QEMU running in the source node to know which pages are still
+missing in the destination node. The bitmap in the source node is
+checked to find which missing pages to send in round robin and we seek
+over it when receiving incoming userfaults. After sending each page of
+course the bitmap is updated accordingly. It's also useful to avoid
+sending the same page twice (in case the userfault is read by the
+postcopy thread just before UFFDIO_COPY|ZEROPAGE runs in the migration
+thread).

+	  capable processors, accesses to pages with PTE_AF cleared will

+ * Note on the 64 bit inline asm variants...

+ * and this is used for the 32 bit version, however 'U' does not appear to work
+ * for 64 bit values (gcc-4.9)
+ *
+ * The exact constraint is that conditional instructions cannot deal with an
+ * immediate displacement in the memory reference, so what we do is we read the
+ * address through a volatile cast into a local variable in order to insure we
+ * _have_ to compute the correct address without displacement. This allows us
+ * to use the regular 'm' for the memory address.
+ *
+ * Furthermore, the %Ln operand, which prints the low word register (r+1),
+ * really only works for registers, this means we cannot allow immediate values
+ * for the 64 bit versions -- like we do for the 32 bit ones.

+ * The AXI-DMAC is a soft IP core that is used in FPGA designs. The core has

+ * by the core.
+ *
+ * Each channel of the core has a source interface and a destination interface.
+ * The number of channels and the type of the channel interfaces is selected at
+ * configuration time. A interface can either be a connected to a central memory
+ * interconnect, which allows access to system memory, or it can be connected to
+ * a dedicated bus which is directly connected to a data port on a peripheral.
+ * Given that those are configuration options of the core that are selected when
+ * it is instantiated this means that they can not be changed by software at
+ * runtime. By extension this means that each channel is uni-directional. It can
+ * either be device to memory or memory to device, but not both. Also since the
+ * device side is a dedicated data bus only connected to a single peripheral
+ * there is no address than can or needs to be configured for the device side.

+/**
+ * DOC: fence register handling
+ *
+ * Important to avoid confusions: "fences" in the i915 driver are not execution
+ * fences used to track command completion but hardware detiler objects which
+ * wrap a given range of the global GTT. Each platform has only a fairly limited
+ * set of these objects.
+ *
+ * Fences are used to detile GTT memory mappings. They're also connected to the
+ * hardware frontbuffer render tracking and hence interract with frontbuffer
+ * conmpression. Furthermore on older platforms fences are required for tiled
+ * objects used by the display engine. They can also be used by the render
+ * engine - they're required for blitter commands and are optional for render
+ * commands. But on gen4+ both display (with the exception of fbc) and rendering
+ * have their own tiling state bits and don't need fences.
+ *
+ * Also note that fences only support X and Y tiling and hence can't be used for
+ * the fancier new tiling formats like W, Ys and Yf.
+ *
+ * Finally note that because fences are such a restricted resource they're
+ * dynamically associated with objects. Furthermore fence state is committed to
+ * the hardware lazily to avoid unecessary stalls on gen2/3. Therefore code must
+ * explictly call i915_gem_object_get_fence() to synchronize fencing status
+ * for cpu access. Also note that some code wants an unfenced view, for those
+ * cases the fence can be removed forcefully with i915_gem_object_put_fence().
+ *
+ * Internally these functions will synchronize with userspace access by removing
+ * CPU ptes into GTT mmaps (not the GTT ptes themselves) as needed.

+/**
+ * DOC: tiling swizzling details
+ *
+ * The idea behind tiling is to increase cache hit rates by rearranging
+ * pixel data so that a group of pixel accesses are in the same cacheline.
+ * Performance improvement from doing this on the back/depth buffer are on
+ * the order of 30%.
+ *
+ * Intel architectures make this somewhat more complicated, though, by
+ * adjustments made to addressing of data when the memory is in interleaved
+ * mode (matched pairs of DIMMS) to improve memory bandwidth.
+ * For interleaved memory, the CPU sends every sequential 64 bytes
+ * to an alternate memory channel so it can get the bandwidth from both.
+ *
+ * The GPU also rearranges its accesses for increased bandwidth to interleaved
+ * memory, and it matches what the CPU does for non-tiled.  However, when tiled
+ * it does it a little differently, since one walks addresses not just in the
+ * X direction but also Y.  So, along with alternating channels when bit
+ * 6 of the address flips, it also alternates when other bits flip --  Bits 9
+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
+ * are common to both the 915 and 965-class hardware.
+ *
+ * The CPU also sometimes XORs in higher bits as well, to improve
+ * bandwidth doing strided access like we do so frequently in graphics.  This
+ * is called "Channel XOR Randomization" in the MCH documentation.  The result
+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
+ * decode.
+ *
+ * All of this bit 6 XORing has an effect on our memory management,
+ * as we need to make sure that the 3d driver can correctly address object
+ * contents.
+ *
+ * If we don't have interleaved memory, all tiling is safe and no swizzling is
+ * required.
+ *
+ * When bit 17 is XORed in, we simply refuse to tile at all.  Bit
+ * 17 is not just a page offset, so as we page an objet out and back in,
+ * individual pages in it will have different bit 17 addresses, resulting in
+ * each 64 bytes being swapped with its neighbor!
+ *
+ * Otherwise, if interleaved, we have to tell the 3d driver what the address
+ * swizzling it needs to do is, since it's writing with the CPU to the pages
+ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
+ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
+ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
+ * to match what the GPU expects.

-/** @file i915_gem_tiling.c
- *
- * Support for managing tiling state of buffer objects.
- *
- * The idea behind tiling is to increase cache hit rates by rearranging
- * pixel data so that a group of pixel accesses are in the same cacheline.
- * Performance improvement from doing this on the back/depth buffer are on
- * the order of 30%.
- *
- * Intel architectures make this somewhat more complicated, though, by
- * adjustments made to addressing of data when the memory is in interleaved
- * mode (matched pairs of DIMMS) to improve memory bandwidth.
- * For interleaved memory, the CPU sends every sequential 64 bytes
- * to an alternate memory channel so it can get the bandwidth from both.
- *
- * The GPU also rearranges its accesses for increased bandwidth to interleaved
- * memory, and it matches what the CPU does for non-tiled.  However, when tiled
- * it does it a little differently, since one walks addresses not just in the
- * X direction but also Y.  So, along with alternating channels when bit
- * 6 of the address flips, it also alternates when other bits flip --  Bits 9
- * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines)
- * are common to both the 915 and 965-class hardware.
- *
- * The CPU also sometimes XORs in higher bits as well, to improve
- * bandwidth doing strided access like we do so frequently in graphics.  This
- * is called "Channel XOR Randomization" in the MCH documentation.  The result
- * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address
- * decode.
- *
- * All of this bit 6 XORing has an effect on our memory management,
- * as we need to make sure that the 3d driver can correctly address object
- * contents.
- *
- * If we don't have interleaved memory, all tiling is safe and no swizzling is
- * required.
- *
- * When bit 17 is XORed in, we simply refuse to tile at all.  Bit
- * 17 is not just a page offset, so as we page an objet out and back in,
- * individual pages in it will have different bit 17 addresses, resulting in
- * each 64 bytes being swapped with its neighbor!
- *
- * Otherwise, if interleaved, we have to tell the 3d driver what the address
- * swizzling it needs to do is, since it's writing with the CPU to the pages
- * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the
- * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling
- * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order
- * to match what the GPU expects.

 /**
- * Detects bit 6 swizzling of address lookup between IGD access and CPU
- * access through main memory.
+ * DOC: buffer object tiling
+ *
+ * i915_gem_set_tiling() and i915_gem_get_tiling() is the userspace interface to
+ * declare fence register requirements.
+ *
+ * In principle GEM doesn't care at all about the internal data layout of an
+ * object, and hence it also doesn't care about tiling or swizzling. There's two
+ * exceptions:
+ *
+ * - For X and Y tiling the hardware provides detilers for CPU access, so called
+ *   fences. Since there's only a limited amount of them the kernel must manage
+ *   these, and therefore userspace must tell the kernel the object tiling if it
+ *   wants to use fences for detiling.
+ * - On gen3 and gen4 platforms have a swizzling pattern for tiled objects which
+ *   depends upon the physical page frame number. When swapping such objects the
+ *   page frame number might change and the kernel must be able to fix this up
+ *   and hence now the tiling. Note that on a subset of platforms with
+ *   asymmetric memory channel population the swizzling pattern changes in an
+ *   unknown way, and for those the kernel simply forbids swapping completely.
+ *
+ * Since neither of this applies for new tiling layouts on modern platforms like
+ * W, Ys and Yf tiling GEM only allows object tiling to be set to X or Y tiled.
+ * Anything else can be handled in userspace entirely without the kernel's
+ * invovlement.

+/**
+ * DOC: Hotplug
+ *
+ * Simply put, hotplug occurs when a display is connected to or disconnected
+ * from the system. However, there may be adapters and docking stations and
+ * Display Port short pulses and MST devices involved, complicating matters.
+ *
+ * Hotplug in i915 is handled in many different levels of abstraction.
+ *
+ * The platform dependent interrupt handling code in i915_irq.c enables,
+ * disables, and does preliminary handling of the interrupts. The interrupt
+ * handlers gather the hotplug detect (HPD) information from relevant registers
+ * into a platform independent mask of hotplug pins that have fired.
+ *
+ * The platform independent interrupt handler intel_hpd_irq_handler() in
+ * intel_hotplug.c does hotplug irq storm detection and mitigation, and passes
+ * further processing to appropriate bottom halves (Display Port specific and
+ * regular hotplug).
+ *
+ * The Display Port work function i915_digport_work_func() calls into
+ * intel_dp_hpd_pulse() via hooks, which handles DP short pulses and DP MST long
+ * pulses, with failures and non-MST long pulses triggering regular hotplug
+ * processing on the connector.
+ *
+ * The regular hotplug work function i915_hotplug_work_func() calls connector
+ * detect hooks, and, if connector status changes, triggers sending of hotplug
+ * uevent to userspace via drm_kms_helper_hotplug_event().
+ *
+ * Finally, the userspace is responsible for triggering a modeset upon receiving
+ * the hotplug uevent, disabling or enabling the crtc as needed.
+ *
+ * The hotplug interrupt storm detection and mitigation code keeps track of the
+ * number of interrupts per hotplug pin per a period of time, and if the number
+ * of interrupts exceeds a certain threshold, the interrupt is disabled for a
+ * while before being re-enabled. The intention is to mitigate issues raising
+ * from broken hardware triggering massive amounts of interrupts and grinding
+ * the system to a halt.
+ *
+ * Current implementation expects that hotplug interrupt storm will not be
+ * seen when display port sink is connected, hence on platforms whose DP
+ * callback is handled by i915_digport_work_func reenabling of hpd is not
+ * performed (it was never expected to be disabled in the first place ;) )
+ * this is specific to DP sinks handled by this routine and any other display
+ * such as HDMI or DVI enabled on the same port will have proper logic since
+ * it will use i915_hotplug_work_func where this logic is handled.

+/**
+ * DOC: Memory Objects Control State (MOCS)
+ *
+ * Motivation:
+ * In previous Gens the MOCS settings was a value that was set by user land as
+ * part of the batch. In Gen9 this has changed to be a single table (per ring)
+ * that all batches now reference by index instead of programming the MOCS
+ * directly.
+ *
+ * The one wrinkle in this is that only PART of the MOCS tables are included
+ * in context (The GFX_MOCS_0 - GFX_MOCS_64 and the LNCFCMOCS0 - LNCFCMOCS32
+ * registers). The rest are not (the settings for the other rings).
+ *
+ * This table needs to be set at system start-up because the way the table
+ * interacts with the contexts and the GmmLib interface.
+ *
+ *
+ * Implementation:
+ *
+ * The tables (one per supported platform) are defined in intel_mocs.c
+ * and are programmed in the first batch after the context is loaded
+ * (with the hardware workarounds). This will then let the usual
+ * context handling keep the MOCS in step.

+ * Guest memory regions (GMRs):
+ *
+ * This is a new memory mapping feature available in SVGA devices
+ * which have the SVGA_CAP_GMR bit set. Previously, there were two
+ * fixed memory regions available with which to share data between the
+ * device and the driver: the FIFO ('MEM') and the framebuffer. GMRs
+ * are our name for an extensible way of providing arbitrary DMA
+ * buffers for use between the driver and the SVGA device. They are a
+ * new alternative to framebuffer memory, usable for both 2D and 3D
+ * graphics operations.
+ *
+ * Since GMR mapping must be done synchronously with guest CPU
+ * execution, we use a new pair of SVGA registers:
+ *
+ *   SVGA_REG_GMR_ID --
+ *
+ *     Read/write.
+ *     This register holds the 32-bit ID (a small positive integer)
+ *     of a GMR to create, delete, or redefine. Writing this register
+ *     has no side-effects.
+ *
+ *   SVGA_REG_GMR_DESCRIPTOR --
+ *
+ *     Write-only.
+ *     Writing this register will create, delete, or redefine the GMR
+ *     specified by the above ID register. If this register is zero,
+ *     the GMR is deleted. Any pointers into this GMR (including those
+ *     currently being processed by FIFO commands) will be
+ *     synchronously invalidated.
+ *
+ *     If this register is nonzero, it must be the physical page
+ *     number (PPN) of a data structure which describes the physical
+ *     layout of the memory region this GMR should describe. The
+ *     descriptor structure will be read synchronously by the SVGA
+ *     device when this register is written. The descriptor need not
+ *     remain allocated for the lifetime of the GMR.
+ *
+ *     The guest driver should write SVGA_REG_GMR_ID first, then
+ *     SVGA_REG_GMR_DESCRIPTOR.
+ *
+ *   SVGA_REG_GMR_MAX_IDS --
+ *
+ *     Read-only.
+ *     The SVGA device may choose to support a maximum number of
+ *     user-defined GMR IDs. This register holds the number of supported
+ *     IDs. (The maximum supported ID plus 1)
+ *
+ *   SVGA_REG_GMR_MAX_DESCRIPTOR_LENGTH --
+ *
+ *     Read-only.
+ *     The SVGA device may choose to put a limit on the total number

+ *
+ * The descriptor structure is an array of SVGAGuestMemDescriptor
+ * structures. Each structure may do one of three things:
+ *
+ *   - Terminate the GMR descriptor list.
+ *     (ppn==0, numPages==0)
+ *
+ *   - Add a PPN or range of PPNs to the GMR's virtual address space.
+ *     (ppn != 0, numPages != 0)
+ *
+ *   - Provide the PPN of the next SVGAGuestMemDescriptor, in order to
+ *     support multi-page GMR descriptor tables without forcing the
+ *     driver to allocate physically contiguous memory.
+ *     (ppn != 0, numPages == 0)
+ *
+ * Note that each physical page of SVGAGuestMemDescriptor structures
+ * can describe at least 2MB of guest memory. If the driver needs to
+ * use more than one page of descriptor structures, it must use one of
+ * its SVGAGuestMemDescriptors to point to an additional page.  The
+ * device will never automatically cross a page boundary.
+ *
+ * Once the driver has described a GMR, it is immediately available
+ * for use via any FIFO command that uses an SVGAGuestPtr structure.
+ * These pointers include a GMR identifier plus an offset into that
+ * GMR.
+ *
+ * The driver must check the SVGA_CAP_GMR bit before using the GMR
+ * registers.

+ * Register based command buffers --

+ * Provide an SVGA device interface that allows the guest to submit
+ * command buffers to the SVGA device through an SVGA device register.
+ * The metadata for each command buffer is contained in the
+ * SVGACBHeader structure along with the return status codes.
+ *
+ * The SVGA device supports command buffers if
+ * SVGA_CAP_COMMAND_BUFFERS is set in the device caps register.  The
+ * fifo must be enabled for command buffers to be submitted.
+ *
+ * Command buffers are submitted when the guest writing the 64 byte
+ * aligned physical address into the SVGA_REG_COMMAND_LOW and
+ * SVGA_REG_COMMAND_HIGH.  SVGA_REG_COMMAND_HIGH contains the upper 32
+ * bits of the physical address.  SVGA_REG_COMMAND_LOW contains the
+ * lower 32 bits of the physical address, since the command buffer
+ * headers are required to be 64 byte aligned the lower 6 bits are
+ * used for the SVGACBContext value.  Writing to SVGA_REG_COMMAND_LOW
+ * submits the command buffer to the device and queues it for
+ * execution.  The SVGA device supports at least
+ * SVGA_CB_MAX_QUEUED_PER_CONTEXT command buffers that can be queued
+ * per context and if that limit is reached the device will write the
+ * status SVGA_CB_STATUS_QUEUE_FULL to the status value of the command
+ * buffer header synchronously and not raise any IRQs.
+ *
+ * It is invalid to submit a command buffer without a valid physical
+ * address and results are undefined.
+ *
+ * The device guarantees that command buffers of size SVGA_CB_MAX_SIZE
+ * will be supported.  If a larger command buffer is submitted results
+ * are unspecified and the device will either complete the command
+ * buffer or return an error.
+ *
+ * The device guarantees that any individual command in a command
+ * buffer can be up to SVGA_CB_MAX_COMMAND_SIZE in size which is
+ * enough to fit a 64x64 color-cursor definition.  If the command is
+ * too large the device is allowed to process the command or return an
+ * error.
+ *
+ * The device context is a special SVGACBContext that allows for
+ * synchronous register like accesses with the flexibility of
+ * commands.  There is a different command set defined by
+ * SVGADeviceContextCmdId.  The commands in each command buffer is not
+ * allowed to straddle physical pages.
+ *
+ * The offset field which is available starting with the
+ * SVGA_CAP_CMD_BUFFERS_2 cap bit can be set by the guest to bias the
+ * start of command processing into the buffer.  If an error is
+ * encountered the errorOffset will still be relative to the specific
+ * PA, not biased by the offset.  When the command buffer is finished
+ * the guest should not read the offset field as there is no guarantee

+/*
+ * FIFO Synchronization Registers
+ *
+ *  This explains the relationship between the various FIFO
+ *  sync-related registers in IOSpace and in FIFO space.
+ *
+ *  SVGA_REG_SYNC --
+ *
+ *       The SYNC register can be used in two different ways by the guest:
+ *
+ *         1. If the guest wishes to fully sync (drain) the FIFO,
+ *            it will write once to SYNC then poll on the BUSY
+ *            register. The FIFO is sync'ed once BUSY is zero.
+ *
+ *         2. If the guest wants to asynchronously wake up the host,
+ *            it will write once to SYNC without polling on BUSY.
+ *            Ideally it will do this after some new commands have
+ *            been placed in the FIFO, and after reading a zero
+ *            from SVGA_FIFO_BUSY.
+ *
+ *       (1) is the original behaviour that SYNC was designed to
+ *       support.  Originally, a write to SYNC would implicitly
+ *       trigger a read from BUSY. This causes us to synchronously
+ *       process the FIFO.
+ *
+ *       This behaviour has since been changed so that writing SYNC
+ *       will *not* implicitly cause a read from BUSY. Instead, it
+ *       makes a channel call which asynchronously wakes up the MKS
+ *       thread.
+ *
+ *       New guests can use this new behaviour to implement (2)
+ *       efficiently. This lets guests get the host's attention
+ *       without waiting for the MKS to poll, which gives us much
+ *       better CPU utilization on SMP hosts and on UP hosts while
+ *       we're blocked on the host GPU.
+ *
+ *       Old guests shouldn't notice the behaviour change. SYNC was
+ *       never guaranteed to process the entire FIFO, since it was
+ *       bounded to a particular number of CPU cycles. Old guests will
+ *       still loop on the BUSY register until the FIFO is empty.
+ *
+ *       Writing to SYNC currently has the following side-effects:
+ *
+ *         - Sets SVGA_REG_BUSY to TRUE (in the monitor)
+ *         - Asynchronously wakes up the MKS thread for FIFO processing
+ *         - The value written to SYNC is recorded as a "reason", for
+ *           stats purposes.
+ *
+ *       If SVGA_FIFO_BUSY is available, drivers are advised to only
+ *       write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
+ *       SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
+ *       eventually set SVGA_FIFO_BUSY on its own, but this approach
+ *       lets the driver avoid sending multiple asynchronous wakeup
+ *       messages to the MKS thread.
+ *
+ *  SVGA_REG_BUSY --
+ *
+ *       This register is set to TRUE when SVGA_REG_SYNC is written,
+ *       and it reads as FALSE when the FIFO has been completely
+ *       drained.
+ *
+ *       Every read from this register causes us to synchronously
+ *       process FIFO commands. There is no guarantee as to how many
+ *       commands each read will process.
+ *
+ *       CPU time spent processing FIFO commands will be billed to
+ *       the guest.
+ *
+ *       New drivers should avoid using this register unless they
+ *       need to guarantee that the FIFO is completely drained. It
+ *       is overkill for performing a sync-to-fence. Older drivers
+ *       will use this register for any type of synchronization.
+ *
+ *  SVGA_FIFO_BUSY --
+ *
+ *       This register is a fast way for the guest driver to check
+ *       whether the FIFO is already being processed. It reads and
+ *       writes at normal RAM speeds, with no monitor intervention.
+ *
+ *       If this register reads as TRUE, the host is guaranteeing that
+ *       any new commands written into the FIFO will be noticed before
+ *       the MKS goes back to sleep.
+ *
+ *       If this register reads as FALSE, no such guarantee can be
+ *       made.
+ *
+ *       The guest should use this register to quickly determine
+ *       whether or not it needs to wake up the host. If the guest
+ *       just wrote a command or group of commands that it would like
+ *       the host to begin processing, it should:
+ *
+ *         1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
+ *            action is necessary.
+ *
+ *         2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
+ *            code that we've already sent a SYNC to the host and we
+ *            don't need to send a duplicate.
+ *
+ *         3. Write a reason to SVGA_REG_SYNC. This will send an
+ *            asynchronous wakeup to the MKS thread.

+ *    dynamically create and destroy 'screens', which can represent
+ *    Unity windows or virtual monitors. Screen Object also provides
+ *    strong guarantees that DMA operations happen only when
+ *    guest-initiated. Screen Object deprecates the BAR1 guest
+ *    framebuffer (GFB) and all commands that work only with the GFB.
+ *
+ *    New registers:
+ *       FIFO_CURSOR_SCREEN_ID, VIDEO_DATA_GMRID, VIDEO_DST_SCREEN_ID
+ *
+ *    New 2D commands:

+ *       BLIT_SCREEN_TO_GMRFB, ANNOTATION_FILL, ANNOTATION_COPY
+ *
+ *    New 3D commands:
+ *       BLIT_SURFACE_TO_SCREEN
+ *
+ *    New guarantees:
+ *
+ *       - The host will not read or write guest memory, including the GFB,
+ *         except when explicitly initiated by a DMA command.
+ *
+ *       - All DMA, including legacy DMA like UPDATE and PRESENT_READBACK,
+ *         is guaranteed to complete before any subsequent FENCEs.
+ *
+ *       - All legacy commands which affect a Screen (UPDATE, PRESENT,
+ *         PRESENT_READBACK) as well as new Screen blit commands will
+ *         all behave consistently as blits, and memory will be read
+ *         or written in FIFO order.
+ *
+ *         For example, if you PRESENT from one SVGA3D surface to multiple
+ *         places on the screen, the data copied will always be from the
+ *         SVGA3D surface at the time the PRESENT was issued in the FIFO.
+ *         This was not necessarily true on devices without Screen Object.
+ *
+ *         This means that on devices that support Screen Object, the
+ *         PRESENT_READBACK command should not be necessary unless you
+ *         actually want to read back the results of 3D rendering into
+ *         system memory. (And for that, the BLIT_SCREEN_TO_GMRFB
+ *         command provides a strict superset of functionality.)
+ *
+ *       - When a screen is resized, either using Screen Object commands or
+ *         legacy multimon registers, its contents are preserved.
+ *
+ * SVGA_FIFO_CAP_GMR2 --

+ *    Provides new commands to define and remap guest memory regions (GMR).
+ *
+ *    New 2D commands:

+ *
+ * SVGA_FIFO_CAP_3D_HWVERSION_REVISED --
+ *
+ *    Indicates new register SVGA_FIFO_3D_HWVERSION_REVISED exists.
+ *    This register may replace SVGA_FIFO_3D_HWVERSION on platforms
+ *    that enforce graphics resource limits.  This allows the platform
+ *    to clear SVGA_FIFO_3D_HWVERSION and disable 3D in legacy guest
+ *    drivers that do not limit their resources.
+ *
+ *    Note this is an alias to SVGA_FIFO_CAP_GMR2 because these indicators
+ *    are codependent (and thus we use a single capability bit).
+ *

+ *
+ *    Modifies the DEFINE_SCREEN command to include a guest provided
+ *    backing store in GMR memory and the bytesPerLine for the backing
+ *    store.  This capability requires the use of a backing store when

+ *    is present then backing stores are optional.

+ * SVGA_CMD_DEFINE_GMRFB --
+ *
+ *    This command sets a piece of SVGA device state called the
+ *    Guest Memory Region Framebuffer, or GMRFB. The GMRFB is a
+ *    piece of light-weight state which identifies the location and
+ *    format of an image in guest memory or in BAR1. The GMRFB has
+ *    an arbitrary size, and it doesn't need to match the geometry
+ *    of the GFB or any screen object.
+ *
+ *    The GMRFB can be redefined as often as you like. You could
+ *    always use the same GMRFB, you could redefine it before
+ *    rendering from a different guest screen, or you could even
+ *    redefine it before every blit.
+ *
+ *    There are multiple ways to use this command. The simplest way is
+ *    to use it to move the framebuffer either to elsewhere in the GFB
+ *    (BAR1) memory region, or to a user-defined GMR. This lets a
+ *    driver use a framebuffer allocated entirely out of normal system
+ *    memory, which we encourage.
+ *
+ *    Another way to use this command is to set up a ring buffer of
+ *    updates in GFB memory. If a driver wants to ensure that no
+ *    frames are skipped by the SVGA device, it is important that the
+ *    driver not modify the source data for a blit until the device is
+ *    done processing the command. One efficient way to accomplish
+ *    this is to use a ring of small DMA buffers. Each buffer is used
+ *    for one blit, then we move on to the next buffer in the
+ *    ring. The FENCE mechanism is used to protect each buffer from
+ *    re-use until the device is finished with that buffer's
+ *    corresponding blit.
+ *
+ *    This command does not affect the meaning of SVGA_CMD_UPDATE.
+ *    UPDATEs always occur from the legacy GFB memory area. This
+ *    command has no support for pseudocolor GMRFBs. Currently only
+ *    true-color 15, 16, and 24-bit depths are supported. Future
+ *    devices may expose capabilities for additional framebuffer
+ *    formats.
+ *
+ *    The default GMRFB value is undefined. Drivers must always send
+ *    this command at least once before performing any blit from the
+ *    GMRFB.

- *
- *    This command takes an optional variable-length list of clipping

- *    drawn to. If one or more rectangles are included, they describe

- *    relative to the top-left corner of destRect.
- *
- *    This clipping region serves multiple purposes:
- *
- *      - It can be used to perform an irregularly shaped blit more
- *        efficiently than by issuing many separate blit commands.
- *
- *      - It is equivalent to allowing blits with non-integer

-/*
- * Guest memory regions (GMRs):
- *
- * This is a new memory mapping feature available in SVGA devices
- * which have the SVGA_CAP_GMR bit set. Previously, there were two
- * fixed memory regions available with which to share data between the
- * device and the driver: the FIFO ('MEM') and the framebuffer. GMRs
- * are our name for an extensible way of providing arbitrary DMA
- * buffers for use between the driver and the SVGA device. They are a
- * new alternative to framebuffer memory, usable for both 2D and 3D
- * graphics operations.
- *
- * Since GMR mapping must be done synchronously with guest CPU
- * execution, we use a new pair of SVGA registers:
- *
- *   SVGA_REG_GMR_ID --
- *
- *     Read/write.
- *     This register holds the 32-bit ID (a small positive integer)
- *     of a GMR to create, delete, or redefine. Writing this register
- *     has no side-effects.
- *
- *   SVGA_REG_GMR_DESCRIPTOR --
- *
- *     Write-only.
- *     Writing this register will create, delete, or redefine the GMR
- *     specified by the above ID register. If this register is zero,
- *     the GMR is deleted. Any pointers into this GMR (including those
- *     currently being processed by FIFO commands) will be
- *     synchronously invalidated.
- *
- *     If this register is nonzero, it must be the physical page
- *     number (PPN) of a data structure which describes the physical
- *     layout of the memory region this GMR should describe. The
- *     descriptor structure will be read synchronously by the SVGA
- *     device when this register is written. The descriptor need not
- *     remain allocated for the lifetime of the GMR.
- *
- *     The guest driver should write SVGA_REG_GMR_ID first, then
- *     SVGA_REG_GMR_DESCRIPTOR.
- *
- *   SVGA_REG_GMR_MAX_IDS --
- *
- *     Read-only.
- *     The SVGA device may choose to support a maximum number of
- *     user-defined GMR IDs. This register holds the number of supported
- *     IDs. (The maximum supported ID plus 1)
- *
- *   SVGA_REG_GMR_MAX_DESCRIPTOR_LENGTH --
- *
- *     Read-only.
- *     The SVGA device may choose to put a limit on the total number
- *     of SVGAGuestMemDescriptor structures it will read when defining
- *     a single GMR.
- *
- * The descriptor structure is an array of SVGAGuestMemDescriptor
- * structures. Each structure may do one of three things:
- *
- *   - Terminate the GMR descriptor list.
- *     (ppn==0, numPages==0)
- *
- *   - Add a PPN or range of PPNs to the GMR's virtual address space.
- *     (ppn != 0, numPages != 0)
- *
- *   - Provide the PPN of the next SVGAGuestMemDescriptor, in order to
- *     support multi-page GMR descriptor tables without forcing the
- *     driver to allocate physically contiguous memory.
- *     (ppn != 0, numPages == 0)
- *
- * Note that each physical page of SVGAGuestMemDescriptor structures
- * can describe at least 2MB of guest memory. If the driver needs to
- * use more than one page of descriptor structures, it must use one of
- * its SVGAGuestMemDescriptors to point to an additional page.  The
- * device will never automatically cross a page boundary.
- *
- * Once the driver has described a GMR, it is immediately available
- * for use via any FIFO command that uses an SVGAGuestPtr structure.
- * These pointers include a GMR identifier plus an offset into that
- * GMR.
- *
- * The driver must check the SVGA_CAP_GMR bit before using the GMR
- * registers.
- */
-
-/*
- * Special GMR IDs, allowing SVGAGuestPtrs to point to framebuffer
- * memory as well.  In the future, these IDs could even be used to
- * allow legacy memory regions to be redefined by the guest as GMRs.
- *
- * Using the guest framebuffer (GFB) at BAR1 for general purpose DMA
- * is being phased out. Please try to use user-defined GMRs whenever
- * possible.

-/*
- * FIFO Synchronization Registers
- *
- *  This explains the relationship between the various FIFO
- *  sync-related registers in IOSpace and in FIFO space.
- *
- *  SVGA_REG_SYNC --
- *
- *       The SYNC register can be used in two different ways by the guest:
- *
- *         1. If the guest wishes to fully sync (drain) the FIFO,
- *            it will write once to SYNC then poll on the BUSY
- *            register. The FIFO is sync'ed once BUSY is zero.
- *
- *         2. If the guest wants to asynchronously wake up the host,
- *            it will write once to SYNC without polling on BUSY.
- *            Ideally it will do this after some new commands have
- *            been placed in the FIFO, and after reading a zero
- *            from SVGA_FIFO_BUSY.
- *
- *       (1) is the original behaviour that SYNC was designed to
- *       support.  Originally, a write to SYNC would implicitly
- *       trigger a read from BUSY. This causes us to synchronously
- *       process the FIFO.
- *
- *       This behaviour has since been changed so that writing SYNC
- *       will *not* implicitly cause a read from BUSY. Instead, it
- *       makes a channel call which asynchronously wakes up the MKS
- *       thread.
- *
- *       New guests can use this new behaviour to implement (2)
- *       efficiently. This lets guests get the host's attention
- *       without waiting for the MKS to poll, which gives us much
- *       better CPU utilization on SMP hosts and on UP hosts while
- *       we're blocked on the host GPU.
- *
- *       Old guests shouldn't notice the behaviour change. SYNC was
- *       never guaranteed to process the entire FIFO, since it was
- *       bounded to a particular number of CPU cycles. Old guests will
- *       still loop on the BUSY register until the FIFO is empty.
- *
- *       Writing to SYNC currently has the following side-effects:
- *
- *         - Sets SVGA_REG_BUSY to TRUE (in the monitor)
- *         - Asynchronously wakes up the MKS thread for FIFO processing
- *         - The value written to SYNC is recorded as a "reason", for
- *           stats purposes.
- *
- *       If SVGA_FIFO_BUSY is available, drivers are advised to only
- *       write to SYNC if SVGA_FIFO_BUSY is FALSE. Drivers should set
- *       SVGA_FIFO_BUSY to TRUE after writing to SYNC. The MKS will
- *       eventually set SVGA_FIFO_BUSY on its own, but this approach
- *       lets the driver avoid sending multiple asynchronous wakeup
- *       messages to the MKS thread.
- *
- *  SVGA_REG_BUSY --
- *
- *       This register is set to TRUE when SVGA_REG_SYNC is written,
- *       and it reads as FALSE when the FIFO has been completely
- *       drained.
- *
- *       Every read from this register causes us to synchronously
- *       process FIFO commands. There is no guarantee as to how many
- *       commands each read will process.
- *
- *       CPU time spent processing FIFO commands will be billed to
- *       the guest.
- *
- *       New drivers should avoid using this register unless they
- *       need to guarantee that the FIFO is completely drained. It
- *       is overkill for performing a sync-to-fence. Older drivers
- *       will use this register for any type of synchronization.
- *
- *  SVGA_FIFO_BUSY --
- *
- *       This register is a fast way for the guest driver to check
- *       whether the FIFO is already being processed. It reads and
- *       writes at normal RAM speeds, with no monitor intervention.
- *
- *       If this register reads as TRUE, the host is guaranteeing that
- *       any new commands written into the FIFO will be noticed before
- *       the MKS goes back to sleep.
- *
- *       If this register reads as FALSE, no such guarantee can be
- *       made.
- *
- *       The guest should use this register to quickly determine
- *       whether or not it needs to wake up the host. If the guest
- *       just wrote a command or group of commands that it would like
- *       the host to begin processing, it should:
- *
- *         1. Read SVGA_FIFO_BUSY. If it reads as TRUE, no further
- *            action is necessary.
- *
- *         2. Write TRUE to SVGA_FIFO_BUSY. This informs future guest
- *            code that we've already sent a SYNC to the host and we
- *            don't need to send a duplicate.
- *
- *         3. Write a reason to SVGA_REG_SYNC. This will send an
- *            asynchronous wakeup to the MKS thread.

- *
- * XXX: Add longer descriptions for each capability, including a list
- *      of the new features that each capability provides.
- *
- * SVGA_FIFO_CAP_SCREEN_OBJECT --
- *
- *    Provides dynamic multi-screen rendering, for improved Unity and
- *    multi-monitor modes. With Screen Object, the guest can
- *    dynamically create and destroy 'screens', which can represent
- *    Unity windows or virtual monitors. Screen Object also provides
- *    strong guarantees that DMA operations happen only when
- *    guest-initiated. Screen Object deprecates the BAR1 guest
- *    framebuffer (GFB) and all commands that work only with the GFB.
- *
- *    New registers:
- *       FIFO_CURSOR_SCREEN_ID, VIDEO_DATA_GMRID, VIDEO_DST_SCREEN_ID
- *
- *    New 2D commands:
- *       DEFINE_SCREEN, DESTROY_SCREEN, DEFINE_GMRFB, BLIT_GMRFB_TO_SCREEN,
- *       BLIT_SCREEN_TO_GMRFB, ANNOTATION_FILL, ANNOTATION_COPY
- *
- *    New 3D commands:
- *       BLIT_SURFACE_TO_SCREEN
- *
- *    New guarantees:
- *
- *       - The host will not read or write guest memory, including the GFB,
- *         except when explicitly initiated by a DMA command.
- *
- *       - All DMA, including legacy DMA like UPDATE and PRESENT_READBACK,
- *         is guaranteed to complete before any subsequent FENCEs.
- *
- *       - All legacy commands which affect a Screen (UPDATE, PRESENT,
- *         PRESENT_READBACK) as well as new Screen blit commands will
- *         all behave consistently as blits, and memory will be read
- *         or written in FIFO order.
- *
- *         For example, if you PRESENT from one SVGA3D surface to multiple
- *         places on the screen, the data copied will always be from the
- *         SVGA3D surface at the time the PRESENT was issued in the FIFO.
- *         This was not necessarily true on devices without Screen Object.
- *
- *         This means that on devices that support Screen Object, the
- *         PRESENT_READBACK command should not be necessary unless you
- *         actually want to read back the results of 3D rendering into
- *         system memory. (And for that, the BLIT_SCREEN_TO_GMRFB
- *         command provides a strict superset of functionality.)
- *
- *       - When a screen is resized, either using Screen Object commands or
- *         legacy multimon registers, its contents are preserved.
- *
- * SVGA_FIFO_CAP_GMR2 --
- *
- *    Provides new commands to define and remap guest memory regions (GMR).
- *
- *    New 2D commands:
- *       DEFINE_GMR2, REMAP_GMR2.
- *
- * SVGA_FIFO_CAP_3D_HWVERSION_REVISED --
- *
- *    Indicates new register SVGA_FIFO_3D_HWVERSION_REVISED exists.
- *    This register may replace SVGA_FIFO_3D_HWVERSION on platforms
- *    that enforce graphics resource limits.  This allows the platform
- *    to clear SVGA_FIFO_3D_HWVERSION and disable 3D in legacy guest
- *    drivers that do not limit their resources.
- *
- *    Note this is an alias to SVGA_FIFO_CAP_GMR2 because these indicators
- *    are codependent (and thus we use a single capability bit).
- *
- * SVGA_FIFO_CAP_SCREEN_OBJECT_2 --
- *
- *    Modifies the DEFINE_SCREEN command to include a guest provided
- *    backing store in GMR memory and the bytesPerLine for the backing
- *    store.  This capability requires the use of a backing store when
- *    creating screen objects.  However if SVGA_FIFO_CAP_SCREEN_OBJECT
- *    is present then backing stores are optional.
- *
- * SVGA_FIFO_CAP_DEAD --

- *    Drivers should not use this cap bit.  This cap bit can not be

- * SVGA_CMD_DEFINE_GMRFB --
- *
- *    This command sets a piece of SVGA device state called the
- *    Guest Memory Region Framebuffer, or GMRFB. The GMRFB is a
- *    piece of light-weight state which identifies the location and
- *    format of an image in guest memory or in BAR1. The GMRFB has
- *    an arbitrary size, and it doesn't need to match the geometry
- *    of the GFB or any screen object.
- *
- *    The GMRFB can be redefined as often as you like. You could
- *    always use the same GMRFB, you could redefine it before
- *    rendering from a different guest screen, or you could even
- *    redefine it before every blit.
- *
- *    There are multiple ways to use this command. The simplest way is
- *    to use it to move the framebuffer either to elsewhere in the GFB
- *    (BAR1) memory region, or to a user-defined GMR. This lets a
- *    driver use a framebuffer allocated entirely out of normal system
- *    memory, which we encourage.
- *
- *    Another way to use this command is to set up a ring buffer of
- *    updates in GFB memory. If a driver wants to ensure that no
- *    frames are skipped by the SVGA device, it is important that the
- *    driver not modify the source data for a blit until the device is
- *    done processing the command. One efficient way to accomplish
- *    this is to use a ring of small DMA buffers. Each buffer is used
- *    for one blit, then we move on to the next buffer in the
- *    ring. The FENCE mechanism is used to protect each buffer from
- *    re-use until the device is finished with that buffer's
- *    corresponding blit.
- *
- *    This command does not affect the meaning of SVGA_CMD_UPDATE.
- *    UPDATEs always occur from the legacy GFB memory area. This
- *    command has no support for pseudocolor GMRFBs. Currently only
- *    true-color 15, 16, and 24-bit depths are supported. Future
- *    devices may expose capabilities for additional framebuffer
- *    formats.

- *    The default GMRFB value is undefined. Drivers must always send

+ * This file implements the vmwgfx context binding manager,

+ * backed contexts can be swapped out to their backing mobs by the device
+ * at any time, also swapped in at any time. At swapin time, the device
+ * validates the context bindings to make sure they point to valid resources.
+ * It's this outside-of-drawcall validation (that can happen at any time),
+ * that makes this code necessary.
+ *
+ * We therefore need to kill any context bindings pointing to a resource
+ * when the resource is swapped out. Furthermore, if the vmwgfx driver has
+ * swapped out the context we can't swap it in again to kill bindings because
+ * of backing mob reservation lockdep violations, so as part of
+ * context swapout, also kill all bindings of a context, so that they are
+ * already killed if a resource to which a binding points
+ * needs to be swapped out.
+ *
+ * Note that a resource can be pointed to by bindings from multiple contexts,
+ * Therefore we can't easily protect this data by a per context mutex
+ * (unless we use deadlock-safe WW mutexes). So we use a global binding_mutex
+ * to protect all binding manager data.
+ *
+ * Finally, any association between a context and a global resource
+ * (surface, shader or even DX query) is conceptually a context binding that

-config INFINIBAND_IPATH
-	tristate "QLogic HTX HCA support"
-	depends on 64BIT && NET && HT_IRQ
-	---help---
-	This is a driver for the obsolete QLogic Hyper-Transport
-	IB host channel adapter (model QHT7140),
-	including InfiniBand verbs support.  This driver allows these
-	devices to be used with both kernel upper level protocols such
-	as IP-over-InfiniBand as well as with userspace applications
-	(in conjunction with InfiniBand userspace access).
-	For QLogic PCIe QLE based cards, use the QIB driver instead.
-
-	If you have this hardware you will need to boot with PAT disabled
-	on your x86-64 systems, use the nopat kernel parameter.

+
+	  The driver currently supports C8SECTPFE's TS input block,
+	  memdma engine, and HW PID filtering.
+
+	  Supported DVB front-end cards are:
+	  - STMicroelectronics DVB-T B2100A (STV0367 + TDA18212)
+	  - STMicroelectronics DVB-S/S2 STV0903 + STV6110 + LNBP24 board
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called c8sectpfe.

+	 *    cxl_get_context). If you've attached IRQs or other
+	 *    resources to it, they remains yours to free.
+	 *
+	 * You can call the same functions to release resources as you
+	 * normally would: we make sure that these functions continue
+	 * to work when the hardware is down.
+	 *
+	 * Two examples:
+	 *
+	 * 1) If you normally free all your resources at the end of
+	 *    each request, or if you use anonymous FDs, your
+	 *    error_detected callback can simply set a flag to tell
+	 *    your driver not to start any new calls. You can then
+	 *    clear the flag in the resume callback.
+	 *
+	 * 2) If you normally allocate your resources on startup:
+	 *     * Set a flag in error_detected as above.
+	 *     * Let CXL detach your contexts.

+/*
+ * Power button, Home button, Volume buttons support is supposed to
+ * be covered by drivers/input/misc/soc_button_array.c, which is implemented
+ * according to "Windows ACPI Design Guide for SoC Platforms".
+ * However surface pro3 seems not to obey the specs, instead it uses
+ * device VGBI(MSHW0028) for dispatching the events.
+ * We choose acpi_driver rather than platform_driver/i2c_driver because
+ * although VGBI has an i2c resource connected to i2c controller, it
+ * is not embedded in any i2c controller's scope, thus neither platform_device
+ * will be created, nor i2c_client will be enumerated, we have to use
+ * acpi_driver.

+ * Notes
+ * =====
+ * NXP LPC18xx provides a State Configurable Timer (SCT) which can be configured
+ * as a Pulse Width Modulator.
+ *
+ * SCT supports 16 outputs, 16 events and 16 registers. Each event will be
+ * triggered when its related register matches the SCT counter value, and it
+ * will set or clear a selected output.
+ *
+ * One of the events is preselected to generate the period, thus the maximum
+ * number of simultaneous channels is limited to 15. Notice that period is
+ * global to all the channels, thus PWM driver will refuse setting different
+ * values to it, unless there's only one channel requested.

+ *   and errors
+ */
+
+/**
+ * DOC: sdma PSM/verbs API
+ *
+ * The sdma API is designed to be used by both PSM
+ * and verbs to supply packets to the SDMA ring.
+ *
+ * The usage of the API is as follows:
+ *
+ * Embed a struct iowait in the QP or
+ * PQ.  The iowait should be initialized with a
+ * call to iowait_init().
+ *
+ * The user of the API should create an allocation method
+ * for their version of the txreq. slabs, pre-allocated lists,
+ * and dma pools can be used.  Once the user's overload of
+ * the sdma_txreq has been allocated, the sdma_txreq member
+ * must be initialized with sdma_txinit() or sdma_txinit_ahg().
+ *
+ * The txreq must be declared with the sdma_txreq first.
+ *
+ * The tx request, once initialized,  is manipulated with calls to
+ * sdma_txadd_daddr(), sdma_txadd_page(), or sdma_txadd_kvaddr()
+ * for each disjoint memory location.  It is the user's responsibility
+ * to understand the packet boundaries and page boundaries to do the
+ * appropriate number of sdma_txadd_* calls..  The user
+ * must be prepared to deal with failures from these routines due to
+ * either memory allocation or dma_mapping failures.
+ *
+ * The mapping specifics for each memory location are recorded
+ * in the tx. Memory locations added with sdma_txadd_page()
+ * and sdma_txadd_kvaddr() are automatically mapped when added
+ * to the tx and nmapped as part of the progress processing in the
+ * SDMA interrupt handling.
+ *
+ * sdma_txadd_daddr() is used to add an dma_addr_t memory to the
+ * tx.   An example of a use case would be a pre-allocated
+ * set of headers allocated via dma_pool_alloc() or
+ * dma_alloc_coherent().  For these memory locations, it
+ * is the responsibility of the user to handle that unmapping.
+ * (This would usually be at an unload or job termination.)
+ *
+ * The routine sdma_send_txreq() is used to submit
+ * a tx to the ring after the appropriate number of
+ * sdma_txadd_* have been done.
+ *
+ * If it is desired to send a burst of sdma_txreqs, sdma_send_txlist()
+ * can be used to submit a list of packets.
+ *
+ * The user is free to use the link overhead in the struct sdma_txreq as
+ * long as the tx isn't in flight.
+ *
+ * The extreme degenerate case of the number of descriptors
+ * exceeding the ring size is automatically handled as
+ * memory locations are added.  An overflow of the descriptor
+ * array that is part of the sdma_txreq is also automatically
+ * handled.
+ *
+ */
+
+/**
+ * DOC: Infrastructure calls
+ *
+ * sdma_init() is used to initialize data structures and
+ * CSRs for the desired number of SDMA engines.
+ *
+ * sdma_start() is used to kick the SDMA engines initialized
+ * with sdma_init().   Interrupts must be enabled at this
+ * point since aspects of the state machine are interrupt
+ * driven.
+ *
+ * sdma_engine_error() and sdma_engine_interrupt() are
+ * entrances for interrupts.
+ *
+ * sdma_map_init() is for the management of the mapping
+ * table when the number of vls is changed.

+	including InfiniBand verbs support.  This driver allows these
+	devices to be used with both kernel upper level protocols such

+	(in conjunction with InfiniBand userspace access).
+	For QLogic PCIe QLE based cards, use the QIB driver instead.
+
+	If you have this hardware you will need to boot with PAT disabled
+	on your x86-64 systems, use the nopat kernel parameter.
+
+	Note that this driver will soon be removed entirely from the kernel.

-config EXT3_FS
-	tristate "Ext3 journalling file system support"
-	select JBD
-	help
-	  This is the journalling version of the Second extended file system
-	  (often called ext3), the de facto standard Linux file system
-	  (method to organize files on a storage device) for hard disks.
-
-	  The journalling code included in this driver means you do not have
-	  to run e2fsck (file system checker) on your file systems after a
-	  crash.  The journal keeps track of any changes that were being made
-	  at the time the system crashed, and can ensure that your file system
-	  is consistent without the need for a lengthy check.
-
-	  Other than adding the journal to the file system, the on-disk format
-	  of ext3 is identical to ext2.  It is possible to freely switch
-	  between using the ext3 driver and the ext2 driver, as long as the
-	  file system has been cleanly unmounted, or e2fsck is run on the file
-	  system.
-
-	  To add a journal on an existing ext2 file system or change the
-	  behavior of ext3 file systems, you can use the tune2fs utility ("man
-	  tune2fs").  To modify attributes of files and directories on ext3
-	  file systems, use chattr ("man chattr").  You need to be using
-	  e2fsprogs version 1.20 or later in order to create ext3 journals
-	  (available at <http://sourceforge.net/projects/e2fsprogs/>).
-
-	  To compile this file system support as a module, choose M here: the
-	  module will be called ext3.
-
-config EXT3_DEFAULTS_TO_ORDERED
-	bool "Default to 'data=ordered' in ext3"
-	depends on EXT3_FS
-	default y
-	help
-	  The journal mode options for ext3 have different tradeoffs
-	  between when data is guaranteed to be on disk and
-	  performance.	The use of "data=writeback" can cause
-	  unwritten data to appear in files after an system crash or
-	  power failure, which can be a security issue.	 However,
-	  "data=ordered" mode can also result in major performance
-	  problems, including seconds-long delays before an fsync()
-	  call returns.	 For details, see:
-
-	  http://ext4.wiki.kernel.org/index.php/Ext3_data_mode_tradeoffs
-
-	  If you have been historically happy with ext3's performance,
-	  data=ordered mode will be a safe choice and you should
-	  answer 'y' here.  If you understand the reliability and data
-	  privacy issues of data=writeback and are willing to make
-	  that trade off, answer 'n'.
-
-config EXT3_FS_XATTR
-	bool "Ext3 extended attributes"
-	depends on EXT3_FS
-	default y
-	help
-	  Extended attributes are name:value pairs associated with inodes by
-	  the kernel or by users (see the attr(5) manual page, or visit
-	  <http://acl.bestbits.at/> for details).
-
-	  If unsure, say N.
-
-	  You need this for POSIX ACL support on ext3.
-
-config EXT3_FS_POSIX_ACL
-	bool "Ext3 POSIX Access Control Lists"
-	depends on EXT3_FS_XATTR
-	select FS_POSIX_ACL
-	help
-	  Posix Access Control Lists (ACLs) support permissions for users and
-	  groups beyond the owner/group/world scheme.
-
-	  To learn more about Access Control Lists, visit the Posix ACLs for
-	  Linux website <http://acl.bestbits.at/>.
-
-	  If you don't know what Access Control Lists are, say N
-
-config EXT3_FS_SECURITY
-	bool "Ext3 Security Labels"
-	depends on EXT3_FS_XATTR
-	help
-	  Security labels support alternative access control models
-	  implemented by security modules like SELinux.  This option
-	  enables an extended attribute handler for file security
-	  labels in the ext3 filesystem.
-
-	  If you are not using a security module that requires using
-	  extended attributes for file security labels, say N.

- * Extended attributes are stored directly in inodes (on file systems with
- * inodes bigger than 128 bytes) and on additional disk blocks. The i_file_acl
- * field contains the block number if an inode uses an additional block. All
- * attributes must fit in the inode and one additional block. Blocks that
- * contain the identical set of attributes may be shared among several inodes.
- * Identical blocks are detected by keeping a cache of blocks that have
- * recently been accessed.
- *
- * The attributes in inodes and on blocks have a different header; the entries
- * are stored in the same format:
- *
- *   +------------------+
- *   | header           |
- *   | entry 1          | |
- *   | entry 2          | | growing downwards
- *   | entry 3          | v
- *   | four null bytes  |
- *   | . . .            |
- *   | value 1          | ^
- *   | value 3          | | growing upwards
- *   | value 2          | |
- *   +------------------+
- *
- * The header is followed by multiple entry descriptors. In disk blocks, the
- * entry descriptors are kept sorted. In inodes, they are unsorted. The
- * attribute values are aligned to the end of the block in no specific order.
- *
- * Locking strategy
- * ----------------
- * EXT3_I(inode)->i_file_acl is protected by EXT3_I(inode)->xattr_sem.
- * EA blocks are only changed if they are exclusive to an inode, so
- * holding xattr_sem also means that nothing but the EA block's reference
- * count can change. Multiple writers to the same block are synchronized
- * by the buffer lock.

-	tristate

-	  This is a generic journalling layer for block devices.  It is
-	  currently used by the ext3 file system, but it could also be
-	  used to add journal support to other file systems or block
-	  devices such as RAID or LVM.
-
-	  If you are using the ext3 file system, you need to say Y here.
-	  If you are not using ext3 then you will probably want to say N.
-
-	  To compile this device as a module, choose M here: the module will be
-	  called jbd.  If you are compiling ext3 into the kernel, you
-	  cannot compile this code as a module.
-
-config JBD_DEBUG
-	bool "JBD (ext3) debugging support"
-	depends on JBD && DEBUG_FS
-	help
-	  If you are using the ext3 journaled file system (or potentially any
-	  other file system/device using JBD), this option allows you to
-	  enable debugging output while the system is running, in order to
-	  help track down any problems you are having.  By default the
-	  debugging output will be turned off.
-
-	  If you select Y here, then you will be able to turn on debugging
-	  with "echo N > /sys/kernel/debug/jbd/jbd-debug", where N is a
-	  number between 1 and 5, the higher the number, the more debugging
-	  output is generated.  To turn debugging off again, do
-	  "echo 0 > /sys/kernel/debug/jbd/jbd-debug".

- *
- * Journal revoke routines for the generic filesystem journaling code;
- * part of the ext2fs journaling system.
- *
- * Revoke is the mechanism used to prevent old log records for deleted
- * metadata from being replayed on top of newer data using the same
- * blocks.  The revoke mechanism is used in two separate places:
- *
- * + Commit: during commit we write the entire list of the current
- *   transaction's revoked blocks to the journal
- *
- * + Recovery: during recovery we record the transaction ID of all
- *   revoked blocks.  If there are multiple revoke records in the log
- *   for a single block, only the last one counts, and if there is a log
- *   entry for a block beyond the last revoke, then that log entry still
- *   gets replayed.
- *
- * We can get interactions between revokes and new log data within a
- * single transaction:
- *
- * Block is revoked and then journaled:
- *   The desired end result is the journaling of the new block, so we
- *   cancel the revoke before the transaction commits.
- *
- * Block is journaled and then revoked:
- *   The revoke must take precedence over the write of the block, so we
- *   need either to cancel the journal entry or to write the revoke
- *   later in the log than the log block.  In this case, we choose the
- *   latter: journaling a block cancels any revoke record for that block
- *   in the current transaction, so any revoke for that block in the
- *   transaction must have happened after the block was journaled and so
- *   the revoke must take precedence.
- *
- * Block is revoked and then written as data:
- *   The data write is allowed to succeed, but the revoke is _not_
- *   cancelled.  We still need to prevent old log records from
- *   overwriting the new data.  We don't even need to clear the revoke
- *   bit here.
- *
- * We cache revoke status of a buffer in the current transaction in b_states
- * bits.  As the name says, revokevalid flag indicates that the cached revoke
- * status of a buffer is valid and we can rely on the cached status.
- *
- * Revoke information on buffers is a tri-state value:
- *
- * RevokeValid clear:	no cached revoke status, need to look it up
- * RevokeValid set, Revoked clear:
- *			buffer has not been revoked, and cancel_revoke
- *			need do nothing.
- * RevokeValid set, Revoked set:
- *			buffer has been revoked.
- *
- * Locking rules:
- * We keep two hash tables of revoke records. One hashtable belongs to the
- * running transaction (is pointed to by journal->j_revoke), the other one
- * belongs to the committing transaction. Accesses to the second hash table
- * happen only from the kjournald and no other thread touches this table.  Also
- * journal_switch_revoke_table() which switches which hashtable belongs to the
- * running and which to the committing transaction is called only from
- * kjournald. Therefore we need no locks when accessing the hashtable belonging
- * to the committing transaction.
- *
- * All users operating on the hash table belonging to the running transaction
- * have a handle to the transaction. Therefore they are safe from kjournald
- * switching hash tables under them. For operations on the lists of entries in
- * the hash table j_revoke_lock is used.
- *
- * Finally, also replay code uses the hash tables but at this moment no one else
- * can touch them (filesystem isn't mounted yet) and hence no locking is
- * needed.

  * Jump labels provide an interface to generate dynamic branches using

+ * Similarly, we can define an initially true key via

+ * initially true or false can be using in both static_branch_unlikely()
+ * and static_branch_likely() statements.

- * However at runtime we can change the branch target using
- * static_key_slow_{inc,dec}(). These function as a 'reference' count on the key
- * object, and for as long as there are references all branches referring to
- * that particular key will point to the (out of line) true block.
+ * At runtime we can change the branch target by setting the key
+ * to true via a call to static_branch_enable(), or false using

+ * these calls then we run-time modify the branch target via a
+ * no-op -> jump or jump -> no-op conversion. For example, for an
+ * initially false key that is used in an "if (static_branch_unlikely(&key))"

+ * static_branch_inc() can be thought of as a 'make more true' and
+ * static_branch_dec() as a 'make more false'. The inc()/dec()
+ * interface is meant to be used exclusively from the inc()/dec() for a given
+ * key.
+ *
+ * Since this relies on modifying code, the branch modifying functions

+ * Process number limiting controller for cgroups.
+ *
+ * Used to allow a cgroup hierarchy to stop any new processes from fork()ing
+ * after a certain limit is reached.
+ *
+ * Since it is trivial to hit the task limit without hitting any kmemcg limits
+ * in place, PIDs are a fundamental resource. As such, PID exhaustion must be
+ * preventable in the scope of a cgroup hierarchy by allowing resource limiting
+ * of the number of tasks in a cgroup.
+ *
+ * In order to use the `pids` controller, set the maximum number of tasks in
+ * pids.max (this is not available in the root cgroup for obvious reasons). The
+ * number of processes currently in the cgroup is given by pids.current.
+ * Organisational operations are not blocked by cgroup policies, so it is
+ * possible to have pids.current > pids.max. However, it is not possible to
+ * violate a cgroup policy through fork(). fork() will return -EAGAIN if forking
+ * would cause a cgroup policy to be violated.
+ *
+ * To set a cgroup to have no limit, set pids.max to "max". This is the default
+ * for all new cgroups (N.B. that PID limits are hierarchical, so the most
+ * stringent limit in the hierarchy is followed).
+ *
+ * pids.current tracks all child cgroup hierarchies, so parent/pids.current is
+ * a superset of parent/child/pids.current.

- *
- * In that environment kexec copies the new kernel to its final
- * resting place.  This means I can only support memory whose

- * addresses where (pfn << PAGE_SHIFT) > ULONG_MAX cannot be handled.
- * If the assembly stub has more restrictive requirements
- * KEXEC_SOURCE_MEMORY_LIMIT and KEXEC_DEST_MEMORY_LIMIT can be
- * defined more restrictively in <asm/kexec.h>.
- *
- * The code for the transition from the current kernel to the
- * the new kernel is placed in the control_code_buffer, whose size
- * is given by KEXEC_CONTROL_PAGE_SIZE.  In the best case only a single
- * page of memory is necessary, but some architectures require more.
- * Because this memory must be identity mapped in the transition from
- * virtual to physical addresses it must live in the range
- * 0 - TASK_SIZE, as only the user space mappings are arbitrarily
- * modifiable.
- *
- * The assembly stub in the control code buffer is passed a linked list
- * of descriptor pages detailing the source pages of the new kernel,
- * and the destination addresses of those source pages.  As this data
- * structure is not used in the context of the current OS, it must
- * be self-contained.
- *
- * The code has been made to work with highmem pages and will use a
- * destination page in its final resting place (if it happens
- * to allocate it).  The end product of this is that most of the
- * physical address space, and most of RAM can be used.
- *
- * Future directions include:
- *  - allocating a page table with the control code buffer identity
- *    mapped, to simplify machine_kexec and make kexec_on_panic more

+ * the new kernel is placed in the control_code_buffer, whose size
+ * is given by KEXEC_CONTROL_PAGE_SIZE.  In the best case only a single

+ * Because this memory must be identity mapped in the transition from
+ * virtual to physical addresses it must live in the range
+ * 0 - TASK_SIZE, as only the user space mappings are arbitrarily
+ * modifiable.
+ *
+ * The assembly stub in the control code buffer is passed a linked list
+ * of descriptor pages detailing the source pages of the new kernel,
+ * and the destination addresses of those source pages.  As this data
+ * structure is not used in the context of the current OS, it must
+ * be self-contained.
+ *
+ * The code has been made to work with highmem pages and will use a

+ * to allocate it).  The end product of this is that most of the
+ * physical address space, and most of RAM can be used.

+ * @write:	whether pages will be written to by the caller
+ * @force:	whether to force write access even if user mapping is
+ *		readonly. See description of the same argument of
+		get_user_pages().
+ * @vec:	structure which receives pages / pfns of the addresses mapped.
+ *		It should have space for at least nr_frames entries.
+ *
+ * This function maps virtual addresses from @start and fills @vec structure
+ * with page frame numbers or page pointers to corresponding pages (choice
+ * depends on the type of the vma underlying the virtual address). If @start
+ * belongs to a normal vma, the function grabs reference to each of the pages
+ * to pin them in memory. If @start belongs to VM_IO | VM_PFNMAP vma, we don't
+ * touch page structures and the caller must make sure pfns aren't reused for
+ * anything else while he is using them.
+ *
+ * The function returns number of pages mapped which may be less than
+ * @nr_frames. In particular we stop mapping if there are more vmas of
+ * different type underlying the specified range of virtual addresses.
+ * When the function isn't able to map a single page, it returns error.
+ *

+# When a Kconfig string contains a filename, it is suitable for
+# passing to shell commands. It is surrounded by double-quotes, and
+# any double-quotes or backslashes within it are escaped by
+# backslashes.
+#
+# This is no use for dependencies or $(wildcard). We need to strip the
+# surrounding quotes and the escaping from quotes and backslashes, and
+# we *do* need to escape any spaces in the string. So, for example:
+#
+# Usage: $(eval $(call config_filename,FOO))
+#
+# Defines FOO_FILENAME based on the contents of the CONFIG_FOO option,
+# transformed as described above to be suitable for use within the
+# makefile.
+#
+# Also, if the filename is a relative filename and exists in the source
+# tree but not the build tree, define FOO_SRCPREFIX as $(srctree)/ to
+# be prefixed to *both* command invocation and dependencies.
+#
+# Note: We also print the filenames in the quiet_cmd_foo text, and
+# perhaps ought to have a version specially escaped for that purpose.
+# But it's only cosmetic, and $(patsubst "%",%,$(CONFIG_FOO)) is good
+# enough.  It'll strip the quotes in the common case where there's no
+# space and it's a simple filename, and it'll retain the quotes when
+# there's a space. There are some esoteric cases in which it'll print
+# the wrong thing, but we don't really care. The actual dependencies
+# and commands *do* get it right, with various combinations of single
+# and double quotes, backslashes and spaces in the filenames.

+ *
+ * This test allocates two virtual areas and bounces the physical
+ * memory across the two virtual areas (from area_src to area_dst)
+ * using userfaultfd.
+ *
+ * There are three threads running per CPU:
+ *
+ * 1) one per-CPU thread takes a per-page pthread_mutex in a random
+ *    page of the area_dst (while the physical page may still be in
+ *    area_src), and increments a per-page counter in the same page,
+ *    and checks its value against a verification region.
+ *
+ * 2) another per-CPU thread handles the userfaults generated by
+ *    thread 1 above. userfaultfd blocking reads or poll() modes are
+ *    exercised interleaved.
+ *
+ * 3) one last per-CPU thread transfers the memory in the background
+ *    at maximum bandwidth (if not already transferred by thread
+ *    2). Each cpu thread takes cares of transferring a portion of the
+ *    area.
+ *
+ * When all threads of type 3 completed the transfer, one bounce is
+ * complete. area_src and area_dst are then swapped. All threads are
+ * respawned and so the bounce is immediately restarted in the
+ * opposite direction.
+ *
+ * per-CPU threads 1 by triggering userfaults inside
+ * pthread_mutex_lock will also verify the atomicity of the memory
+ * transfer (UFFDIO_COPY).
+ *
+ * The program takes two parameters: the amounts of physical memory in
+ * megabytes (MiB) of the area and the number of bounces to execute.
+ *
+ * # 100MiB 99999 bounces
+ * ./userfaultfd 100 99999

+zram: Compressed RAM based block devices
+----------------------------------------
+* Introduction
+
+The zram module creates RAM based block devices named /dev/zram<id>
+(<id> = 0, 1, ...). Pages written to these disks are compressed and stored
+in memory itself. These disks allow very fast I/O and compression provides
+good amounts of memory savings. Some of the usecases include /tmp storage,
+use as swap disks, various caches under /var and maybe many more :)
+
+Statistics for individual zram devices are exported through sysfs nodes at
+/sys/block/zram<id>/
+
+Kconfig required:
+CONFIG_ZRAM=y
+CONFIG_ZRAM_LZ4_COMPRESS=y
+CONFIG_ZPOOL=y
+CONFIG_ZSMALLOC=y
+
+ZRAM Testcases
+--------------
+zram_lib.sh: create library with initialization/cleanup functions
+zram.sh: For sanity check of CONFIG_ZRAM and to run zram01 and zram02
+
+Two functional tests: zram01 and zram02:
+zram01.sh: creates general purpose ram disks with ext4 filesystems
+zram02.sh: creates block device for swap
+
+Commands required for testing:
+ - bc
+ - dd
+ - free
+ - awk
+ - mkswap
+ - swapon
+ - swapoff
+ - mkfs/ mkfs.ext4
+
+For more information please refer:
