+in the "bad block list" will fail with EIO ("Input/output error").
+
+Writes of blocks in the "bad block list will result in the following:
+
+1. Remove the block from the "bad block list".
+2. Successfully complete the write.
+
+This emulates the "remapped sector" behavior of a drive with bad
+sectors.
+
+Normally, a drive that is encountering bad sectors will most likely
+encounter more bad sectors, at an unknown time or location.
+With dm-dust, the user can use the "addbadblock" and "removebadblock"
+messages to add arbitrary bad blocks at new locations, and the
+"enable" and "disable" messages to modulate the state of whether the
+configured "bad blocks" will be treated as bad, or bypassed.
+This allows the pre-writing of test data and metadata prior to
+simulating a "failure" event where bad sectors start to appear.
+
+Table parameters
+----------------
+<device_path> <offset> <blksz>
+
+Mandatory parameters:
+ <device_path>:
+ Path to the block device.
+
+ <offset>:
+ Offset to data area from start of device_path
+
+ <blksz>:
+ Block size in bytes
+
+ (minimum 512, maximum 1073741824, must be a power of 2)
+
+Usage instructions
+------------------
+
+First, find the size (in 512-byte sectors) of the device to be used::
+
+ $ sudo blockdev --getsz /dev/vdb1
+ 33552384
+
+Create the dm-dust device:
+(For a device with a block size of 512 bytes)
+
+::
+
+ $ sudo dmsetup create dust1 --table '0 33552384 dust /dev/vdb1 0 512'
+
+(For a device with a block size of 4096 bytes)
+
+::
+
+ $ sudo dmsetup create dust1 --table '0 33552384 dust /dev/vdb1 0 4096'
+
+Check the status of the read behavior ("bypass" indicates that all I/O
+will be passed through to the underlying device)::
+
+ $ sudo dmsetup status dust1
+ 0 33552384 dust 252:17 bypass
+
+ $ sudo dd if=/dev/mapper/dust1 of=/dev/null bs=512 count=128 iflag=direct
+ 128+0 records in
+ 128+0 records out
+
+ $ sudo dd if=/dev/zero of=/dev/mapper/dust1 bs=512 count=128 oflag=direct
+ 128+0 records in
+ 128+0 records out
+
+Adding and removing bad blocks
+------------------------------
+
+At any time (i.e.: whether the device has the "bad block" emulation
+enabled or disabled), bad blocks may be added or removed from the
+device via the "addbadblock" and "removebadblock" messages::
+
+ $ sudo dmsetup message dust1 0 addbadblock 60
+ kernel: device-mapper: dust: badblock added at block 60
+
+ $ sudo dmsetup message dust1 0 addbadblock 67
+ kernel: device-mapper: dust: badblock added at block 67
+
+ $ sudo dmsetup message dust1 0 addbadblock 72
+ kernel: device-mapper: dust: badblock added at block 72
+
+These bad blocks will be stored in the "bad block list".
+While the device is in "bypass" mode, reads and writes will succeed::
+
+ $ sudo dmsetup status dust1
+ 0 33552384 dust 252:17 bypass
+
+Enabling block read failures
+----------------------------
+
+To enable the "fail read on bad block" behavior, send the "enable" message::
+
+ $ sudo dmsetup message dust1 0 enable
+ kernel: device-mapper: dust: enabling read failures on bad sectors
+
+ $ sudo dmsetup status dust1
+ 0 33552384 dust 252:17 fail_read_on_bad_block
+
+With the device in "fail read on bad block" mode, attempting to read a
+block will encounter an "Input/output error"::
+
+ $ sudo dd if=/dev/mapper/dust1 of=/dev/null bs=512 count=1 skip=67 iflag=direct
+ dd: error reading '/dev/mapper/dust1': Input/output error
+ 0+0 records in
+ 0+0 records out
+ 0 bytes copied, 0.00040651 s, 0.0 kB/s
+
+...and writing to the bad blocks will remove the blocks from the list,
+therefore emulating the "remap" behavior of hard disk drives::
+
+ $ sudo dd if=/dev/zero of=/dev/mapper/dust1 bs=512 count=128 oflag=direct
+ 128+0 records in
+ 128+0 records out
+
+ kernel: device-mapper: dust: block 60 removed from badblocklist by write
+ kernel: device-mapper: dust: block 67 removed from badblocklist by write
+ kernel: device-mapper: dust: block 72 removed from badblocklist by write
+ kernel: device-mapper: dust: block 87 removed from badblocklist by write
+
+Bad block add/remove error handling
+-----------------------------------
+
+Attempting to add a bad block that already exists in the list will
+result in an "Invalid argument" error, as well as a helpful message::
+
+ $ sudo dmsetup message dust1 0 addbadblock 88
+ device-mapper: message ioctl on dust1 failed: Invalid argument
+ kernel: device-mapper: dust: block 88 already in badblocklist
+
+Attempting to remove a bad block that doesn't exist in the list will
+result in an "Invalid argument" error, as well as a helpful message::
+
+ $ sudo dmsetup message dust1 0 removebadblock 87
+ device-mapper: message ioctl on dust1 failed: Invalid argument
+ kernel: device-mapper: dust: block 87 not found in badblocklist
+
+Counting the number of bad blocks in the bad block list
+-------------------------------------------------------
+
+To count the number of bad blocks configured in the device, run the
+following message command::
+
+ $ sudo dmsetup message dust1 0 countbadblocks
+
+A message will print with the number of bad blocks currently
+configured on the device::
+
+ kernel: device-mapper: dust: countbadblocks: 895 badblock(s) found
+
+Querying for specific bad blocks
+--------------------------------
+
+To find out if a specific block is in the bad block list, run the
+following message command::
+
+ $ sudo dmsetup message dust1 0 queryblock 72
+
+The following message will print if the block is in the list::
+
+ device-mapper: dust: queryblock: block 72 found in badblocklist
+
+The following message will print if the block is not in the list::
+
+ device-mapper: dust: queryblock: block 72 not found in badblocklist
+
+The "queryblock" message command will work in both the "enabled"
+and "disabled" modes, allowing the verification of whether a block
+will be treated as "bad" without having to issue I/O to the device,
+or having to "enable" the bad block emulation.
+
+Clearing the bad block list
+---------------------------
+
+To clear the bad block list (without needing to individually run
+a "removebadblock" message command for every block), run the
+following message command::
+
+ $ sudo dmsetup message dust1 0 clearbadblocks
+
+After clearing the bad block list, the following message will appear::
+
+ kernel: device-mapper: dust: clearbadblocks: badblocks cleared
+
+If there were no bad blocks to clear, the following message will
+appear::
+
+ kernel: device-mapper: dust: clearbadblocks: no badblocks found
+
+Message commands list
+---------------------
+
+Below is a list of the messages that can be sent to a dust device:
+
+Operations on blocks (requires a <blknum> argument)::
+
+ addbadblock <blknum>
+ queryblock <blknum>
+ removebadblock <blknum>
+
+...where <blknum> is a block number within range of the device
+(corresponding to the block size of the device.)
+
+Single argument message commands::
+
+ countbadblocks
+ clearbadblocks
+ disable
+ enable
+ quiet
+
+Device removal
+--------------
+
+When finished, remove the device via the "dmsetup remove" command::
+
+ $ sudo dmsetup remove dust1
+
+Quiet mode
+----------
+
+On test runs with many bad blocks, it may be desirable to avoid
+excessive logging (from bad blocks added, removed, or "remapped").
+This can be done by enabling "quiet mode" via the following message::
+
+ $ sudo dmsetup message dust1 0 quiet
+
+This will suppress log messages from add / remove / removed by write
+operations. Log messages from "countbadblocks" or "queryblock"
+message commands will still print in quiet mode.
+
+The status of quiet mode can be seen by running "dmsetup status"::
+
+ $ sudo dmsetup status dust1
+ 0 33552384 dust 252:17 fail_read_on_bad_block quiet
+
+To disable quiet mode, send the "quiet" message again::
+
+ $ sudo dmsetup message dust1 0 quiet
+
+ $ sudo dmsetup status dust1
+ 0 33552384 dust 252:17 fail_read_on_bad_block verbose
+
+(The presence of "verbose" indicates normal logging.)
+
+"Why not...?"
+-------------
+
+scsi_debug has a "medium error" mode that can fail reads on one
+specified sector (sector 0x1234, hardcoded in the source code), but
+it uses RAM for the persistent storage, which drastically decreases
+the potential device size.
+
+dm-flakey fails all I/O from all block locations at a specified time
+frequency, and not a given point in time.
+
+When a bad sector occurs on a hard disk drive, reads to that sector
+are failed by the device, usually resulting in an error code of EIO
+("I/O error") or ENODATA ("No data available"). However, a write to
+the sector may succeed, and result in the sector becoming readable
+after the device controller no longer experiences errors reading the
+sector (or after a reallocation of the sector). However, there may
+be bad sectors that occur on the device in the future, in a different,
+unpredictable location.
+
+This target seeks to provide a device that can exhibit the behavior
+of a bad sector at a known sector location, at a known time, based
+on a large storage device (at least tens of gigabytes, not occupying
+system memory).

-at an arbitrary time.
-
-This target behaves similarly to a linear target. At a given time,
-the user can send a message to the target to start failing read
-requests on specific blocks (to emulate the behavior of a hard disk
-drive with bad sectors).
-
-When the failure behavior is enabled (i.e.: when the output of

-in the "bad block list" will fail with EIO ("Input/output error").
-
-Writes of blocks in the "bad block list will result in the following:

A potential expansion of this mode is a hardware tag-based mode, which would
use hardware memory tagging support instead of compiler instrumentation and
manual shadow memory manipulation.
+
+What memory accesses are sanitised by KASAN?
+--------------------------------------------
+
+The kernel maps memory in a number of different parts of the address
+space. This poses something of a problem for KASAN, which requires
+that all addresses accessed by instrumented code have a valid shadow
+region.
+
+The range of kernel virtual addresses is large: there is not enough
+real memory to support a real shadow region for every address that
+could be accessed by the kernel.
+
+By default
+~~~~~~~~~~
+
+By default, architectures only map real memory over the shadow region
+for the linear mapping (and potentially other small areas). For all
+other areas - such as vmalloc and vmemmap space - a single read-only
+page is mapped over the shadow area. This read-only shadow page
+declares all memory accesses as permitted.
+
+This presents a problem for modules: they do not live in the linear
+mapping, but in a dedicated module space. By hooking in to the module
+allocator, KASAN can temporarily map real shadow memory to cover
+them. This allows detection of invalid accesses to module globals, for
+example.
+
+This also creates an incompatibility with ``VMAP_STACK``: if the stack
+lives in vmalloc space, it will be shadowed by the read-only page, and
+the kernel will fault when trying to set up the shadow data for stack
+variables.
+
+CONFIG_KASAN_VMALLOC
+~~~~~~~~~~~~~~~~~~~~
+
+With ``CONFIG_KASAN_VMALLOC``, KASAN can cover vmalloc space at the
+cost of greater memory usage. Currently this is only supported on x86.
+
+This works by hooking into vmalloc and vmap, and dynamically
+allocating real shadow memory to back the mappings.
+
+Most mappings in vmalloc space are small, requiring less than a full
+page of shadow space. Allocating a full shadow page per mapping would
+therefore be wasteful. Furthermore, to ensure that different mappings
+use different shadow pages, mappings would have to be aligned to
+``KASAN_SHADOW_SCALE_SIZE * PAGE_SIZE``.
+
+Instead, we share backing space across multiple mappings. We allocate
+a backing page when a mapping in vmalloc space uses a particular page
+of the shadow region. This page can be shared by other vmalloc
+mappings later on.
+
+We hook in to the vmap infrastructure to lazily clean up unused shadow
+memory.
+
+To avoid the difficulties around swapping mappings around, we expect
+that the part of the shadow region that covers the vmalloc space will
+not be covered by the early shadow page, but will be left
+unmapped. This will require changes in arch-specific code.
+
+This allows ``VMAP_STACK`` support on x86, and can simplify support of
+architectures that do not have a fixed module region.

+
+Remote coverage collection
+--------------------------
+
+With KCOV_ENABLE coverage is collected only for syscalls that are issued
+from the current process. With KCOV_REMOTE_ENABLE it's possible to collect
+coverage for arbitrary parts of the kernel code, provided that those parts
+are annotated with kcov_remote_start()/kcov_remote_stop().
+
+This allows to collect coverage from two types of kernel background
+threads: the global ones, that are spawned during kernel boot in a limited
+number of instances (e.g. one USB hub_event() worker thread is spawned per
+USB HCD); and the local ones, that are spawned when a user interacts with
+some kernel interface (e.g. vhost workers).
+
+To enable collecting coverage from a global background thread, a unique
+global handle must be assigned and passed to the corresponding
+kcov_remote_start() call. Then a userspace process can pass a list of such
+handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field of the
+kcov_remote_arg struct. This will attach the used kcov device to the code
+sections, that are referenced by those handles.
+
+Since there might be many local background threads spawned from different
+userspace processes, we can't use a single global handle per annotation.
+Instead, the userspace process passes a non-zero handle through the
+common_handle field of the kcov_remote_arg struct. This common handle gets
+saved to the kcov_handle field in the current task_struct and needs to be
+passed to the newly spawned threads via custom annotations. Those threads
+should in turn be annotated with kcov_remote_start()/kcov_remote_stop().
+
+Internally kcov stores handles as u64 integers. The top byte of a handle
+is used to denote the id of a subsystem that this handle belongs to, and
+the lower 4 bytes are used to denote the id of a thread instance within
+that subsystem. A reserved value 0 is used as a subsystem id for common
+handles as they don't belong to a particular subsystem. The bytes 4-7 are
+currently reserved and must be zero. In the future the number of bytes
+used for the subsystem or handle ids might be increased.
+
+When a particular userspace proccess collects coverage by via a common
+handle, kcov will collect coverage for each code section that is annotated
+to use the common handle obtained as kcov_handle from the current
+task_struct. However non common handles allow to collect coverage
+selectively from different subsystems.

-LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
-that can be shared by multiple clients. Clients here are different cores in the
-SOC, the idea is to minimize the local caches at the clients and migrate to
-common pool of memory. Cache memory is divided into partitions called slices
-which are assigned to clients. Clients can query the slice details, activate
-and deactivate them.
-
-Properties:
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be "qcom,sdm845-llcc"
-
-- reg:
- Usage: required
- Value Type: <prop-encoded-array>
- Definition: The first element specifies the llcc base start address and
- the size of the register region. The second element specifies
- the llcc broadcast base address and size of the register region.
-
-- reg-names:
- Usage: required
- Value Type: <stringlist>
- Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
-
-- interrupts:
- Usage: required
- Definition: The interrupt is associated with the llcc edac device.
- It's used for llcc cache single and double bit error detection
- and reporting.
-
-Example:
-
- cache-controller@1100000 {
- compatible = "qcom,sdm845-llcc";
- reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;
- reg-names = "llcc_base", "llcc_broadcast_base";
- interrupts = <GIC_SPI 582 IRQ_TYPE_LEVEL_HIGH>;

-SAMSUNG Exynos SoC series PMU Registers
-
-Properties:
- - compatible : should contain two values. First value must be one from following list:
- - "samsung,exynos3250-pmu" - for Exynos3250 SoC,
- - "samsung,exynos4210-pmu" - for Exynos4210 SoC,
- - "samsung,exynos4412-pmu" - for Exynos4412 SoC,
- - "samsung,exynos5250-pmu" - for Exynos5250 SoC,
- - "samsung,exynos5260-pmu" - for Exynos5260 SoC.
- - "samsung,exynos5410-pmu" - for Exynos5410 SoC,
- - "samsung,exynos5420-pmu" - for Exynos5420 SoC.
- - "samsung,exynos5433-pmu" - for Exynos5433 SoC.
- - "samsung,exynos7-pmu" - for Exynos7 SoC.
- second value must be always "syscon".
-
- - reg : offset and length of the register set.
-
- - #clock-cells : must be <1>, since PMU requires once cell as clock specifier.
- The single specifier cell is used as index to list of clocks
- provided by PMU, which is currently:
- 0 : SoC clock output (CLKOUT pin)
-
- - clock-names : list of clock names for particular CLKOUT mux inputs in
- following format:
- "clkoutN", where N is a decimal number corresponding to
- CLKOUT mux control bits value for given input, e.g.
- "clkout0", "clkout7", "clkout15".
-
- - clocks : list of phandles and specifiers to all input clocks listed in
- clock-names property.
-
-Optional properties:
-
-Some PMUs are capable of behaving as an interrupt controller (mostly
-to wake up a suspended PMU). In which case, they can have the
-following properties:
-
-- interrupt-controller: indicate that said PMU is an interrupt controller
-
-- #interrupt-cells: must be identical to the that of the parent interrupt
- controller.
-
-
-Optional nodes:
-
-- nodes defining the restart and poweroff syscon children
-
-
-Example :
-pmu_system_controller: system-controller@10040000 {
- compatible = "samsung,exynos5250-pmu", "syscon";
- reg = <0x10040000 0x5000>;
- interrupt-controller;
- #interrupt-cells = <3>;
- interrupt-parent = <&gic>;
- #clock-cells = <1>;
- clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
- "clkout4", "clkout8", "clkout9";
- clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>,
- <&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>,
- <&clock CLK_OUT_CPU>, <&clock CLK_XXTI>,
- <&clock CLK_XUSBXTI>;
-};
-
-Example of clock consumer :
-
-usb3503: usb3503@8 {
- /* ... */
- clock-names = "refclk";
- clocks = <&pmu_system_controller 0>;
- /* ... */
-};

-Allwinner SRAM for smp bringup:
-------------------------------------------------
-
-Allwinner's A80 SoC uses part of the secure sram for hotplugging of the
-primary core (cpu0). Once the core gets powered up it checks if a magic
-value is set at a specific location. If it is then the BROM will jump
-to the software entry address, instead of executing a standard boot.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Note that this is separate from the Allwinner SRAM controller found in
-../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to
-any device.
-
-Also there are no "secure-only" properties. The implementation should
-check if this SRAM is usable first.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
- "allwinner,sun9i-a80-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
- sram_b: sram@20000 {
- /* 256 KiB secure SRAM at 0x20000 */
- compatible = "mmio-sram";
- reg = <0x00020000 0x40000>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x00020000 0x40000>;
-
- smp-sram@1000 {
- /*
- * This is checked by BROM to determine if
- * cpu0 should jump to SMP entry vector
- */
- compatible = "allwinner,sun9i-a80-smp-sram";
- reg = <0x1000 0x8>;

-Renesas Bus State Controller (BSC)
-==================================
-
-The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
-Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
-It provides an external bus for connecting multiple external devices to the
-SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
-
-While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
-domain, and may have a gateable functional clock.
-Before a device connected to the BSC can be accessed, the PM domain
-containing the BSC must be powered on, and the functional clock
-driving the BSC must be enabled.
-
-The bindings for the BSC extend the bindings for "simple-pm-bus".
-
-
-Required properties
- - compatible: Must contain an SoC-specific value, and "renesas,bsc" and
- "simple-pm-bus" as fallbacks.
- SoC-specific values can be:
- "renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
- "renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
- - #address-cells, #size-cells, ranges: Must describe the mapping between
- parent address and child address spaces.
- - reg: Must contain the base address and length to access the bus controller.
-
-Optional properties:
- - interrupts: Must contain a reference to the BSC interrupt, if available.
- - clocks: Must contain a reference to the functional clock, if available.
- - power-domains: Must contain a reference to the PM domain, if available.
-

-Simple Power-Managed Bus
-========================
-
-A Simple Power-Managed Bus is a transparent bus that doesn't need a real
-driver, as it's typically initialized by the boot loader.
-
-However, its bus controller is part of a PM domain, or under the control of a
-functional clock. Hence, the bus controller's PM domain and/or clock must be
-enabled for child devices connected to the bus (either on-SoC or externally)
-to function.
-
-While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
-in the Devicetree Specification, it is not an extension of "simple-bus".
-
-
-Required properties:
- - compatible: Must contain at least "simple-pm-bus".
- Must not contain "simple-bus".
- It's recommended to let this be preceded by one or more
- vendor-specific compatible values.
- - #address-cells, #size-cells, ranges: Must describe the mapping between
- parent address and child address spaces.
-
-Optional platform-specific properties for clock or PM domain control (at least
-one of them is required):
- - clocks: Must contain a reference to the functional clock(s),
- - power-domains: Must contain a reference to the PM domain.
-Please refer to the binding documentation for the clock and/or PM domain
-providers for more details.
-
-
-Example:
-
- bsc: bus@fec10000 {
- compatible = "renesas,bsc-sh73a0", "renesas,bsc",
- "simple-pm-bus";
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0 0x20000000>;
- reg = <0xfec10000 0x400>;

-* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
-
-The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
-and several fixed ratio dividers.
-The CPG also provides a Clock Domain for SoC devices, in combination with the
-CPG Module Stop (MSTP) Clocks.
-
-Required Properties:
-
- - compatible: Must be one of
- - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- - "renesas,r8a7792-cpg-clocks" for the r8a7792 CPG
- - "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- - "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
- and "renesas,rcar-gen2-cpg-clocks" as a fallback.
-
- - reg: Base address and length of the memory resource used by the CPG
-
- - clocks: References to the parent clocks: first to the EXTAL clock, second
- to the USB_EXTAL clock
- - #clock-cells: Must be 1
- - clock-output-names: The names of the clocks. Supported clocks are "main",
- "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
- "adsp"
- - #power-domain-cells: Must be 0
-
-SoC devices that are part of the CPG/MSTP Clock Domain and can be power-managed
-through an MSTP clock should refer to the CPG device node in their
-"power-domains" property, as documented by the generic PM domain bindings in
-Documentation/devicetree/bindings/power/power_domain.txt.

-STMicroelectronics STM32 Low-Power Timer quadrature encoder and counter
-
-STM32 Low-Power Timer provides several counter modes. It can be used as:
-- quadrature encoder to detect angular position and direction of rotary
- elements, from IN1 and IN2 input signals.
-- simple counter from IN1 input signal.
-
-Must be a sub-node of an STM32 Low-Power Timer device tree node.
-See ../mfd/stm32-lptimer.txt for details about the parent node.
-
-Required properties:
-- compatible: Must be "st,stm32-lptimer-counter".
-- pinctrl-names: Set to "default". An additional "sleep" state can be
- defined to set pins in sleep state.
-- pinctrl-n: List of phandles pointing to pin configuration nodes,
- to set IN1/IN2 pins in mode of operation for Low-Power
- Timer input on external pin.

- with the same <model> and "atmel" as manufacturer.
-
- Example:
- compatible = "microchip,24c128", "atmel,24c128";
-
- Supported manufacturers are:
-
- "catalyst",
- "microchip",
- "nxp",
- "ramtron",
- "renesas",
- "rohm",
- "st",
-
- Some vendors use different model names for chips which are just
- variants of the above. Known such exceptions are listed below:
-
- "nxp,se97b" - the fallback is "atmel,24c02",
- "renesas,r1ex24002" - the fallback is "atmel,24c02"
- "renesas,r1ex24016" - the fallback is "atmel,24c16"
- "renesas,r1ex24128" - the fallback is "atmel,24c128"
- "rohm,br24t01" - the fallback is "atmel,24c01"
-
- - reg: The I2C address of the EEPROM.
-
-Optional properties:
-
- - pagesize: The length of the pagesize for writing. Please consult the
- manual of your device, that value varies a lot. A wrong value
- may result in data loss! If not specified, a safety value of
- '1' is used which will be very slow.
-
- - read-only: This parameterless property disables writes to the eeprom.
-
- - size: Total eeprom size in bytes.
-
- - no-read-rollover: This parameterless property indicates that the
- multi-address eeprom does not automatically roll over
- reads to the next slave address. Please consult the
- manual of your device.
-
- - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
-
- - address-width: number of address bits (one of 8, 16).

-* ARM SMMUv3 Architecture Implementation
-
-The SMMUv3 architecture is a significant departure from previous
-revisions, replacing the MMIO register interface with in-memory command
-and event queues and adding support for the ATS and PRI components of
-the PCIe specification.
-
-** SMMUv3 required properties:
-
-- compatible : Should include:
-
- * "arm,smmu-v3" for any SMMUv3 compliant
- implementation. This entry should be last in the
- compatible list.
-
-- reg : Base address and size of the SMMU.
-
-- interrupts : Non-secure interrupt list describing the wired
- interrupt sources corresponding to entries in
- interrupt-names. If no wired interrupts are
- present then this property may be omitted.
-
-- interrupt-names : When the interrupts property is present, should
- include the following:
- * "eventq" - Event Queue not empty
- * "priq" - PRI Queue not empty
- * "cmdq-sync" - CMD_SYNC complete
- * "gerror" - Global Error activated
- * "combined" - The combined interrupt is optional,
- and should only be provided if the
- hardware supports just a single,
- combined interrupt line.
- If provided, then the combined interrupt
- will be used in preference to any others.
-
-- #iommu-cells : See the generic IOMMU binding described in
- devicetree/bindings/pci/pci-iommu.txt
- for details. For SMMUv3, must be 1, with each cell
- describing a single stream ID. All possible stream
- IDs which a device may emit must be described.
-
-** SMMUv3 optional properties:
-
-- dma-coherent : Present if DMA operations made by the SMMU (page
- table walks, stream table accesses etc) are cache
- coherent with the CPU.
-
- NOTE: this only applies to the SMMU itself, not
- masters connected upstream of the SMMU.
-
-- msi-parent : See the generic MSI binding described in
- devicetree/bindings/interrupt-controller/msi.txt
- for a description of the msi-parent property.
-
-- hisilicon,broken-prefetch-cmd
- : Avoid sending CMD_PREFETCH_* commands to the SMMU.
-
-- cavium,cn9900-broken-page1-regspace
- : Replaces all page 1 offsets used for EVTQ_PROD/CONS,
- PRIQ_PROD/CONS register access with page 0 offsets.
- Set for Cavium ThunderX2 silicon that doesn't support
- SMMU page1 register space.

-* ARM System MMU Architecture Implementation
-
-ARM SoCs may contain an implementation of the ARM System Memory
-Management Unit Architecture, which can be used to provide 1 or 2 stages
-of address translation to bus masters external to the CPU.
-
-The SMMU may also raise interrupts in response to various fault
-conditions.
-
-** System MMU required properties:
-
-- compatible : Should be one of:
-
- "arm,smmu-v1"
- "arm,smmu-v2"
- "arm,mmu-400"
- "arm,mmu-401"
- "arm,mmu-500"
- "cavium,smmu-v2"
- "qcom,smmu-v2"
-
- depending on the particular implementation and/or the
- version of the architecture implemented.
-
- Qcom SoCs must contain, as below, SoC-specific compatibles
- along with "qcom,smmu-v2":
- "qcom,msm8996-smmu-v2", "qcom,smmu-v2",
- "qcom,sdm845-smmu-v2", "qcom,smmu-v2".
-
- Qcom SoCs implementing "arm,mmu-500" must also include,
- as below, SoC-specific compatibles:
- "qcom,sdm845-smmu-500", "arm,mmu-500"
-
-- reg : Base address and size of the SMMU.
-
-- #global-interrupts : The number of global interrupts exposed by the
- device.
-
-- interrupts : Interrupt list, with the first #global-irqs entries
- corresponding to the global interrupts and any
- following entries corresponding to context interrupts,
- specified in order of their indexing by the SMMU.
-
- For SMMUv2 implementations, there must be exactly one
- interrupt per context bank. In the case of a single,
- combined interrupt, it must be listed multiple times.
-
-- #iommu-cells : See Documentation/devicetree/bindings/iommu/iommu.txt
- for details. With a value of 1, each IOMMU specifier
- represents a distinct stream ID emitted by that device
- into the relevant SMMU.
-
- SMMUs with stream matching support and complex masters
- may use a value of 2, where the second cell of the
- IOMMU specifier represents an SMR mask to combine with
- the ID in the first cell. Care must be taken to ensure
- the set of matched IDs does not result in conflicts.
-
-** System MMU optional properties:
-
-- dma-coherent : Present if page table walks made by the SMMU are
- cache coherent with the CPU.
-
- NOTE: this only applies to the SMMU itself, not
- masters connected upstream of the SMMU.
-
-- calxeda,smmu-secure-config-access : Enable proper handling of buggy
- implementations that always use secure access to
- SMMU configuration registers. In this case non-secure
- aliases of secure registers have to be used during
- SMMU configuration.
-
-- stream-match-mask : For SMMUs supporting stream matching and using
- #iommu-cells = <1>, specifies a mask of bits to ignore
- when matching stream IDs (e.g. this may be programmed
- into the SMRn.MASK field of every stream match register
- used). For cases where it is desirable to ignore some
- portion of every Stream ID (e.g. for certain MMU-500
- configurations given globally unique input IDs). This
- property is not valid for SMMUs using stream indexing,
- or using stream matching with #iommu-cells = <2>, and
- may be ignored if present in such cases.
-
-- clock-names: List of the names of clocks input to the device. The
- required list depends on particular implementation and
- is as follows:
- - for "qcom,smmu-v2":
- - "bus": clock required for downstream bus access and
- for the smmu ptw,
- - "iface": clock required to access smmu's registers
- through the TCU's programming interface.
- - unspecified for other implementations.
-
-- clocks: Specifiers for all clocks listed in the clock-names property,
- as per generic clock bindings.
-
-- power-domains: Specifiers for power domains required to be powered on for
- the SMMU to operate, as per generic power domain bindings.
-
-** Deprecated properties:
-
-- mmu-masters (deprecated in favour of the generic "iommus" binding) :
- A list of phandles to device nodes representing bus
- masters for which the SMMU can provide a translation
- and their corresponding Stream IDs. Each device node
- linked from this list must have a "#stream-id-cells"
- property, indicating the number of Stream ID
- arguments associated with its phandle.
-
-** Examples:
-
- /* SMMU with stream matching or stream indexing */

+Crane Merchandising System - EL15203000 LED driver
+--------------------------------------------------
+
+This LED Board (aka RED LEDs board) is widely used in
+coffee vending machines produced by Crane Merchandising Systems.
+The board manages 3 LEDs and supports predefined blinking patterns
+for specific leds.
+
+Vending area LED encoded with symbol 'V' (hex code 0x56).
+Doesn't have any hardware blinking pattern.
+
+Screen light tube LED which surrounds vending machine screen and
+encoded with symbol 'S' (hex code 0x53). Supports blinking breathing pattern.
+
+Water Pipe LED encoded with symbol 'P' (hex code 0x50) and
+actually consists of 5 LEDs that exposed by protocol like one LED.
+Supports next patterns:
+- cascade pattern
+- inversed cascade pattern
+- bounce pattern
+- inversed bounce pattern
+
+Required properties:
+- compatible : "crane,el15203000"
+- #address-cells : must be 1
+- #size-cells : must be 0
+
+Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
+apply. In particular, "reg" and "spi-max-frequency" properties must be given.
+
+Optional LED sub-node properties:
+- function:
+ see Documentation/devicetree/bindings/leds/common.txt
+- color:
+ see Documentation/devicetree/bindings/leds/common.txt
+
+Example

+* Exynos5422 frequency and voltage scaling for Dynamic Memory Controller device
+
+The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the DRAM
+memory chips are connected. The driver is to monitor the controller in runtime
+and switch frequency and voltage. To monitor the usage of the controller in
+runtime, the driver uses the PPMU (Platform Performance Monitoring Unit), which
+is able to measure the current load of the memory.
+When 'userspace' governor is used for the driver, an application is able to
+switch the DMC and memory frequency.
+
+Required properties for DMC device for Exynos5422:
+- compatible: Should be "samsung,exynos5422-dmc".
+- clocks : list of clock specifiers, must contain an entry for each
+ required entry in clock-names for CLK_FOUT_SPLL, CLK_MOUT_SCLK_SPLL,
+ CLK_FF_DOUT_SPLL2, CLK_FOUT_BPLL, CLK_MOUT_BPLL, CLK_SCLK_BPLL,
+ CLK_MOUT_MX_MSPLL_CCORE, CLK_MOUT_MX_MSPLL_CCORE_PHY, CLK_MOUT_MCLK_CDREX,
+- clock-names : should include "fout_spll", "mout_sclk_spll", "ff_dout_spll2",
+ "fout_bpll", "mout_bpll", "sclk_bpll", "mout_mx_mspll_ccore",
+ "mout_mclk_cdrex" entries
+- devfreq-events : phandles for PPMU devices connected to this DMC.
+- vdd-supply : phandle for voltage regulator which is connected.
+- reg : registers of two CDREX controllers.
+- operating-points-v2 : phandle for OPPs described in v2 definition.
+- device-handle : phandle of the connected DRAM memory device. For more
+ information please refer to documentation file:
+ Documentation/devicetree/bindings/ddr/lpddr3.txt
+- devfreq-events : phandles of the PPMU events used by the controller.
+- samsung,syscon-clk : phandle of the clock register set used by the controller,
+ these registers are used for enabling a 'pause' feature and are not
+ exposed by clock framework but they must be used in a safe way.
+ The register offsets are in the driver code and specyfic for this SoC
+ type.
+
+Optional properties for DMC device for Exynos5422:
+- interrupt-parent : The parent interrupt controller.
+- interrupts : Contains the IRQ line numbers for the DMC internal performance
+ event counters in DREX0 and DREX1 channels. Align with specification of the
+ interrupt line(s) in the interrupt-parent controller.
+- interrupt-names : IRQ names "drex_0" and "drex_1", the order should be the
+ same as in the 'interrupts' list above.
+

+description: |
+ Tegra30 Memory Controller architecturally consists of the following parts:
+
+ Arbitration Domains, which can handle a single request or response per
+ clock from a group of clients. Typically, a system has a single Arbitration
+ Domain, but an implementation may divide the client space into multiple
+ Arbitration Domains to increase the effective system bandwidth.
+
+ Protocol Arbiter, which manage a related pool of memory devices. A system
+ may have a single Protocol Arbiter or multiple Protocol Arbiters.
+
+ Memory Crossbar, which routes request and responses between Arbitration
+ Domains and Protocol Arbiters. In the simplest version of the system, the
+ Memory Crossbar is just a pass through between a single Arbitration Domain
+ and a single Protocol Arbiter.
+
+ Global Resources, which include things like configuration registers which
+ are shared across the Memory Subsystem.
+
+ The Tegra30 Memory Controller handles memory requests from internal clients
+ and arbitrates among them to allocate memory bandwidth for DDR3L and LPDDR2
+ SDRAMs.

-* Allwinner sun8i system controller
-
-This file describes the bindings for the system controller present in
-Allwinner SoC H3, A83T and A64.
-The principal function of this syscon is to control EMAC PHY choice and
-config.
-
-Required properties for the system controller:
-- reg: address and length of the register for the device.
-- compatible: should be "syscon" and one of the following string:
- "allwinner,sun8i-h3-system-controller"
- "allwinner,sun8i-v3s-system-controller"
- "allwinner,sun50i-a64-system-controller"
- "allwinner,sun8i-a83t-system-controller"
-
-Example:
-syscon: syscon@1c00000 {
- compatible = "allwinner,sun8i-h3-system-controller", "syscon";
- reg = <0x01c00000 0x1000>;

+description: |+
+ This is a generic reset driver using syscon to map the reset register.
+ The reset is generally performed with a write to the reset register
+ defined by the register map pointed by syscon reference plus the offset
+ with the value and mask defined in the reboot node.
+ Default will be little endian mode, 32 bit access only.

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+ as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+ as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+ as the "CPU domain" voltage regulator.
+
+Example:
+
+ pmic {
+ regulators {
+ core_vdd_reg: core {
+ regulator-name = "vdd_core";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-core-regulator;
+ };
+
+ rtc_vdd_reg: rtc {
+ regulator-name = "vdd_rtc";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&core_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+

-Amlogic Canvas
-================================
-
-A canvas is a collection of metadata that describes a pixel buffer.
-Those metadata include: width, height, phyaddr, wrapping and block mode.
-Starting with GXBB the endianness can also be described.
-
-Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
-rather than use the phy addresses directly. For instance, this is the case for
-the video decoders and the display.
-
-Amlogic SoCs have 256 canvas.

-* QCOM SoC Temperature Sensor (TSENS)
-
-Required properties:
-- compatible:
- Must be one of the following:
- - "qcom,msm8916-tsens" (MSM8916)
- - "qcom,msm8974-tsens" (MSM8974)
- - "qcom,msm8996-tsens" (MSM8996)
- - "qcom,qcs404-tsens", "qcom,tsens-v1" (QCS404)

- - "qcom,sdm845-tsens", "qcom,tsens-v2" (SDM845)
- The generic "qcom,tsens-v2" property must be used as a fallback for any SoC
- with version 2 of the TSENS IP. MSM8996 is the only exception because the
- generic property did not exist when support was added.
- Similarly, the generic "qcom,tsens-v1" property must be used as a fallback for
- any SoC with version 1 of the TSENS IP.
-
-- reg: Address range of the thermal registers.
- New platforms containing v2.x.y of the TSENS IP must specify the SROT and TM
- register spaces separately, with order being TM before SROT.
- See Example 2, below.
-
-- #thermal-sensor-cells : Should be 1. See ./thermal.txt for a description.
-- #qcom,sensors: Number of sensors in tsens block
-- Refer to Documentation/devicetree/bindings/nvmem/nvmem.txt to know how to specify

-Binding for Thermal Sensor for STMicroelectronics STM32 series of SoCs.
-
-On STM32 SoCs, the Digital Temperature Sensor (DTS) is in charge of managing an
-analog block which delivers a frequency depending on the internal SoC's
-temperature. By using a reference frequency, DTS is able to provide a sample
-number which can be translated into a temperature by the user.
-
-DTS provides interrupt notification mechanism by threshold. This mechanism
-offers two temperature trip points: passive and critical. The first is intended
-for passive cooling notification while the second is used for over-temperature
-reset.
-
-Required parameters:
--------------------
-
-compatible: Should be "st,stm32-thermal"
-reg: This should be the physical base address and length of the
- sensor's registers.
-clocks: Phandle of the clock used by the thermal sensor.
- See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-clock-names: Should be "pclk" for register access clock and reference clock.
- See: Documentation/devicetree/bindings/resource-names.txt
-#thermal-sensor-cells: Should be 0. See ./thermal.txt for a description.
-interrupts: Standard way to define interrupt number.
-
-Example:
-
- thermal-zones {
- cpu_thermal: cpu-thermal {
- polling-delay-passive = <0>;
- polling-delay = <0>;

-Samsung's Multi Core Timer (MCT)

-The Samsung's Multi Core Timer (MCT) module includes two main blocks, the

- should be the order of the interrupts specified. The local timer interrupts
- should be specified after the four global timer interrupts have been

-Amlogic Meson G12A DWC3 USB SoC Controller Glue
-
-The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
-in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
-only.
-
-A glue connects the DWC3 core to USB2 PHYs and optionnaly to an USB3 PHY.
-
-One of the USB2 PHY can be re-routed in peripheral mode to a DWC2 USB IP.
-
-The DWC3 Glue controls the PHY routing and power, an interrupt line is
-connected to the Glue to serve as OTG ID change detection.
-
-Required properties:
-- compatible: Should be "amlogic,meson-g12a-usb-ctrl"
-- clocks: a handle for the "USB" clock
-- resets: a handle for the shared "USB" reset line
-- reg: The base address and length of the registers
-- interrupts: the interrupt specifier for the OTG detection
-- phys: handle to used PHYs on the system
- - a <0> phandle can be used if a PHY is not used
-- phy-names: names of the used PHYs on the system :
- - "usb2-phy0" for USB2 PHY0 if USBHOST_A port is used
- - "usb2-phy1" for USB2 PHY1 if USBOTG_B port is used
- - "usb3-phy0" for USB3 PHY if USB3_0 is used
-- dr_mode: should be "host", "peripheral", or "otg" depending on
- the usage and configuration of the OTG Capable port.
- - "host" and "peripheral" means a fixed Host or Device only connection
- - "otg" means the port can be used as both Host or Device and
- be switched automatically using the OTG ID pin.
-
-Optional properties:
-- vbus-supply: should be a phandle to the regulator controlling the VBUS
- power supply when used in OTG switchable mode
-
-Required child nodes:
-
-A child node must exist to represent the core DWC3 IP block. The name of
-the node is not important. The content of the node is defined in dwc3.txt.
-

+
+This framework provides a standard kernel interface for Dynamic Voltage and
+Frequency Switching on arbitrary devices.
+
+It exposes controls for adjusting frequency through sysfs files which are
+similar to the cpufreq subsystem.
+
+Devices for which current usage can be measured can have their frequency
+automatically adjusted by governors.
+
+API

+
+Device drivers need to initialize a :c:type:`devfreq_profile` and call the
+:c:func:`devfreq_add_device` function to create a :c:type:`devfreq` instance.

+Maintainer Entry Profile
+========================
+
+The Maintainer Entry Profile supplements the top-level process documents
+(submitting-patches, submitting drivers...) with
+subsystem/device-driver-local customs as well as details about the patch
+submission life-cycle. A contributor uses this document to level set
+their expectations and avoid common mistakes, maintainers may use these
+profiles to look across subsystems for opportunities to converge on
+common practices.
+
+
+Overview
+--------
+Provide an introduction to how the subsystem operates. While MAINTAINERS
+tells the contributor where to send patches for which files, it does not
+convey other subsystem-local infrastructure and mechanisms that aid
+development.
+
+Example questions to consider:
+
+- Are there notifications when patches are applied to the local tree, or
+ merged upstream?
+- Does the subsystem have a patchwork instance? Are patchwork state
+ changes notified?
+- Any bots or CI infrastructure that watches the list, or automated
+ testing feedback that the subsystem gates acceptance?
+- Git branches that are pulled into -next?
+- What branch should contributors submit against?
+- Links to any other Maintainer Entry Profiles? For example a
+ device-driver may point to an entry for its parent subsystem. This makes
+ the contributor aware of obligations a maintainer may have have for
+ other maintainers in the submission chain.
+
+
+Submit Checklist Addendum
+-------------------------
+List mandatory and advisory criteria, beyond the common "submit-checklist",
+for a patch to be considered healthy enough for maintainer attention.
+For example: "pass checkpatch.pl with no errors, or warning. Pass the
+unit test detailed at $URI".
+
+The Submit Checklist Addendum can also include details about the status
+of related hardware specifications. For example, does the subsystem
+require published specifications at a certain revision before patches
+will be considered.
+
+
+Key Cycle Dates
+---------------
+One of the common misunderstandings of submitters is that patches can be
+sent at any time before the merge window closes and can still be
+considered for the next -rc1. The reality is that most patches need to
+be settled in soaking in linux-next in advance of the merge window
+opening. Clarify for the submitter the key dates (in terms rc release
+week) that patches might considered for merging and when patches need to
+wait for the next -rc. At a minimum:
+
+- Last -rc for new feature submissions:
+ New feature submissions targeting the next merge window should have
+ their first posting for consideration before this point. Patches that
+ are submitted after this point should be clear that they are targeting
+ the NEXT+1 merge window, or should come with sufficient justification
+ why they should be considered on an expedited schedule. A general
+ guideline is to set expectation with contributors that new feature
+ submissions should appear before -rc5.
+
+- Last -rc to merge features: Deadline for merge decisions
+ Indicate to contributors the point at which an as yet un-applied patch
+ set will need to wait for the NEXT+1 merge window. Of course there is no
+ obligation to ever except any given patchset, but if the review has not
+ concluded by this point the expectation the contributor should wait and
+ resubmit for the following merge window.
+
+Optional:
+
+- First -rc at which the development baseline branch, listed in the
+ overview section, should be considered ready for new submissions.
+
+
+Review Cadence
+--------------
+One of the largest sources of contributor angst is how soon to ping
+after a patchset has been posted without receiving any feedback. In
+addition to specifying how long to wait before a resubmission this
+section can also indicate a preferred style of update like, resend the
+full series, or privately send a reminder email. This section might also
+list how review works for this code area and methods to get feedback
+that are not directly from the maintainer.
+
+Existing profiles
+-----------------
+
+For now, existing maintainer profiles are listed here; we will likely want
+to do something different in the near future.

+Xilinx SD-FEC Driver
+====================
+
+Overview
+========
+
+This driver supports SD-FEC Integrated Block for Zynq |Ultrascale+ (TM)| RFSoCs.
+
+.. |Ultrascale+ (TM)| unicode:: Ultrascale+ U+2122
+ .. with trademark sign
+
+For a full description of SD-FEC core features, see the `SD-FEC Product Guide (PG256) <https://www.xilinx.com/cgi-bin/docs/ipdoc?c=sd_fec;v=latest;d=pg256-sdfec-integrated-block.pdf>`_
+
+This driver supports the following features:
+
+ - Retrieval of the Integrated Block configuration and status information
+ - Configuration of LDPC codes
+ - Configuration of Turbo decoding
+ - Monitoring errors
+
+Missing features, known issues, and limitations of the SD-FEC driver are as
+follows:
+
+ - Only allows a single open file handler to any instance of the driver at any time
+ - Reset of the SD-FEC Integrated Block is not controlled by this driver
+ - Does not support shared LDPC code table wraparound
+
+The device tree entry is described in:
+`linux-xlnx/Documentation/devicetree/bindings/misc/xlnx,sd-fec.txt <https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/misc/xlnx%2Csd-fec.txt>`_
+
+
+Modes of Operation
+------------------
+
+The driver works with the SD-FEC core in two modes of operation:
+
+ - Run-time configuration
+ - Programmable Logic (PL) initialization
+
+
+Run-time Configuration
+~~~~~~~~~~~~~~~~~~~~~~
+
+For Run-time configuration the role of driver is to allow the software application to do the following:
+
+ - Load the configuration parameters for either Turbo decode or LDPC encode or decode
+ - Activate the SD-FEC core
+ - Monitor the SD-FEC core for errors
+ - Retrieve the status and configuration of the SD-FEC core
+
+Programmable Logic (PL) Initialization
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For PL initialization, supporting logic loads configuration parameters for either
+the Turbo decode or LDPC encode or decode. The role of the driver is to allow
+the software application to do the following:
+
+ - Activate the SD-FEC core
+ - Monitor the SD-FEC core for errors
+ - Retrieve the status and configuration of the SD-FEC core
+
+
+Driver Structure
+================
+
+The driver provides a platform device where the ``probe`` and ``remove``
+operations are provided.
+
+ - probe: Updates configuration register with device-tree entries plus determines the current activate state of the core, for example, is the core bypassed or has the core been started.
+
+
+The driver defines the following driver file operations to provide user
+application interfaces:
+
+ - open: Implements restriction that only a single file descriptor can be open per SD-FEC instance at any time
+ - release: Allows another file descriptor to be open, that is after current file descriptor is closed
+ - poll: Provides a method to monitor for SD-FEC Error events
+ - unlocked_ioctl: Provides the the following ioctl commands that allows the application configure the SD-FEC core:
+
+ - :c:macro:`XSDFEC_START_DEV`
+ - :c:macro:`XSDFEC_STOP_DEV`
+ - :c:macro:`XSDFEC_GET_STATUS`
+ - :c:macro:`XSDFEC_SET_IRQ`
+ - :c:macro:`XSDFEC_SET_TURBO`
+ - :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+ - :c:macro:`XSDFEC_GET_CONFIG`
+ - :c:macro:`XSDFEC_SET_ORDER`
+ - :c:macro:`XSDFEC_SET_BYPASS`
+ - :c:macro:`XSDFEC_IS_ACTIVE`
+ - :c:macro:`XSDFEC_CLEAR_STATS`
+ - :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`
+
+
+Driver Usage
+============
+
+
+Overview
+--------
+
+After opening the driver, the user should find out what operations need to be
+performed to configure and activate the SD-FEC core and determine the
+configuration of the driver.
+The following outlines the flow the user should perform:
+
+ - Determine Configuration
+ - Set the order, if not already configured as desired
+ - Set Turbo decode, LPDC encode or decode parameters, depending on how the
+ SD-FEC core is configured plus if the SD-FEC has not been configured for PL
+ initialization
+ - Enable interrupts, if not already enabled
+ - Bypass the SD-FEC core, if required
+ - Start the SD-FEC core if not already started
+ - Get the SD-FEC core status
+ - Monitor for interrupts
+ - Stop the SD-FEC core
+
+
+Note: When monitoring for interrupts if a critical error is detected where a reset is required, the driver will be required to load the default configuration.
+
+
+Determine Configuration
+-----------------------
+
+Determine the configuration of the SD-FEC core by using the ioctl
+:c:macro:`XSDFEC_GET_CONFIG`.
+
+Set the Order
+-------------
+
+Setting the order determines how the order of Blocks can change from input to output.
+
+Setting the order is done by using the ioctl :c:macro:`XSDFEC_SET_ORDER`
+
+Setting the order can only be done if the following restrictions are met:
+
+ - The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+
+Add LDPC Codes
+--------------
+
+The following steps indicate how to add LDPC codes to the SD-FEC core:
+
+ - Use the auto-generated parameters to fill the :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>` for the desired LDPC code.
+ - Set the SC, QA, and LA table offsets for the LPDC parameters and the parameters in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+ - Set the desired Code Id value in the structure :c:type:`struct xsdfec_ldpc_params <xsdfec_ldpc_params>`
+ - Add the LPDC Code Parameters using the ioctl :c:macro:`XSDFEC_ADD_LDPC_CODE_PARAMS`
+ - For the applied LPDC Code Parameter use the function :c:func:`xsdfec_calculate_shared_ldpc_table_entry_size` to calculate the size of shared LPDC code tables. This allows the user to determine the shared table usage so when selecting the table offsets for the next LDPC code parameters unused table areas can be selected.
+ - Repeat for each LDPC code parameter.
+
+Adding LDPC codes can only be done if the following restrictions are met:
+
+ - The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as LDPC
+ - The ``code_wr_protect`` of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates that write protection is not enabled
+ - The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not started
+
+Set Turbo Decode
+----------------
+
+Configuring the Turbo decode parameters is done by using the ioctl :c:macro:`XSDFEC_SET_TURBO` using auto-generated parameters to fill the :c:type:`struct xsdfec_turbo <xsdfec_turbo>` for the desired Turbo code.
+
+Adding Turbo decode can only be done if the following restrictions are met:
+
+ - The ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO
+ - The ``state`` member of struct :c:type:`xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Enable Interrupts
+-----------------
+
+Enabling or disabling interrupts is done by using the ioctl :c:macro:`XSDFEC_SET_IRQ`. The members of the parameter passed, :c:type:`struct xsdfec_irq <xsdfec_irq>`, to the ioctl are used to set and clear different categories of interrupts. The category of interrupt is controlled as following:
+
+ - ``enable_isr`` controls the ``tlast`` interrupts
+ - ``enable_ecc_isr`` controls the ECC interrupts
+
+If the ``code`` member of :c:type:`struct xsdfec_config <xsdfec_config>` filled by the ioctl :c:macro:`XSDFEC_GET_CONFIG` indicates the SD-FEC core is configured as TURBO then the enabling ECC errors is not required.
+
+Bypass the SD-FEC
+-----------------
+
+Bypassing the SD-FEC is done by using the ioctl :c:macro:`XSDFEC_SET_BYPASS`
+
+Bypassing the SD-FEC can only be done if the following restrictions are met:
+
+ - The ``state`` member of :c:type:`struct xsdfec_status <xsdfec_status>` filled by the ioctl :c:macro:`XSDFEC_GET_STATUS` indicates the SD-FEC core has not STARTED
+
+Start the SD-FEC core
+---------------------
+
+Start the SD-FEC core by using the ioctl :c:macro:`XSDFEC_START_DEV`
+
+Get SD-FEC Status
+-----------------
+
+Get the SD-FEC status of the device by using the ioctl :c:macro:`XSDFEC_GET_STATUS`, which will fill the :c:type:`struct xsdfec_status <xsdfec_status>`
+
+Monitor for Interrupts
+----------------------
+
+ - Use the poll system call to monitor for an interrupt. The poll system call waits for an interrupt to wake it up or times out if no interrupt occurs.
+ - On return Poll ``revents`` will indicate whether stats and/or state have been updated
+ - ``POLLPRI`` indicates a critical error and the user should use :c:macro:`XSDFEC_GET_STATUS` and :c:macro:`XSDFEC_GET_STATS` to confirm
+ - ``POLLRDNORM`` indicates a non-critical error has occurred and the user should use :c:macro:`XSDFEC_GET_STATS` to confirm
+ - Get stats by using the ioctl :c:macro:`XSDFEC_GET_STATS`
+ - For critical error the ``isr_err_count`` or ``uecc_count`` member of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+ - For non-critical errors the ``cecc_count`` member of :c:type:`struct xsdfec_stats <xsdfec_stats>` is non-zero
+ - Get state by using the ioctl :c:macro:`XSDFEC_GET_STATUS`
+ - For a critical error the ``state`` of :c:type:`xsdfec_status <xsdfec_status>` will indicate a Reset Is Required
+ - Clear stats by using the ioctl :c:macro:`XSDFEC_CLEAR_STATS`
+
+If a critical error is detected where a reset is required. The application is required to call the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG`, after the reset and it is not required to call the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Note: Using poll system call prevents busy looping using :c:macro:`XSDFEC_GET_STATS` and :c:macro:`XSDFEC_GET_STATUS`
+
+Stop the SD-FEC Core
+---------------------
+
+Stop the device by using the ioctl :c:macro:`XSDFEC_STOP_DEV`
+
+Set the Default Configuration
+-----------------------------
+
+Load default configuration by using the ioctl :c:macro:`XSDFEC_SET_DEFAULT_CONFIG` to restore the driver.
+
+Limitations
+-----------
+
+Users should not duplicate SD-FEC device file handlers, for example fork() or dup() a process that has a created an SD-FEC file handler.

+LIBNVDIMM Maintainer Entry Profile
+==================================
+
+Overview
+--------
+The libnvdimm subsystem manages persistent memory across multiple
+architectures. The mailing list, is tracked by patchwork here:
+https://patchwork.kernel.org/project/linux-nvdimm/list/
+...and that instance is configured to give feedback to submitters on
+patch acceptance and upstream merge. Patches are merged to either the
+'libnvdimm-fixes', or 'libnvdimm-for-next' branch. Those branches are
+available here:
+https://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git/
+
+In general patches can be submitted against the latest -rc, however if
+the incoming code change is dependent on other pending changes then the
+patch should be based on the libnvdimm-for-next branch. However, since
+persistent memory sits at the intersection of storage and memory there
+are cases where patches are more suitable to be merged through a
+Filesystem or the Memory Management tree. When in doubt copy the nvdimm
+list and the maintainers will help route.
+
+Submissions will be exposed to the kbuild robot for compile regression
+testing. It helps to get a success notification from that infrastructure
+before submitting, but it is not required.
+
+
+Submit Checklist Addendum
+-------------------------
+There are unit tests for the subsystem via the ndctl utility:
+https://github.com/pmem/ndctl
+Those tests need to be passed before the patches go upstream, but not
+necessarily before initial posting. Contact the list if you need help
+getting the test environment set up.
+
+### ACPI Device Specific Methods (_DSM)
+Before patches enabling for a new _DSM family will be considered it must
+be assigned a format-interface-code from the NVDIMM Sub-team of the ACPI
+Specification Working Group. In general, the stance of the subsystem is
+to push back on the proliferation of NVDIMM command sets, do strongly
+consider implementing support for an existing command set. See
+drivers/acpi/nfit/nfit.h for the set of support command sets.
+
+
+Key Cycle Dates
+---------------
+New submissions can be sent at any time, but if they intend to hit the
+next merge window they should be sent before -rc4, and ideally
+stabilized in the libnvdimm-for-next branch by -rc6. Of course if a
+patch set requires more than 2 weeks of review -rc4 is already too late
+and some patches may require multiple development cycles to review.
+
+
+Review Cadence
+--------------
+In general, please wait up to one week before pinging for feedback. A
+private mail reminder is preferred. Alternatively ask for other
+developers that have Reviewed-by tags for libnvdimm changes to take a
+look and offer their opinion.

+-----------------------------------
+
+When other developers receive your patches and start the review process,
+it is often useful for them to know where in the tree history they
+should place your work. This is particularly useful for automated CI
+processes that attempt to run a series of tests in order to establish
+the quality of your submission before the maintainer starts the review.
+
+If you are using ``git format-patch`` to generate your patches, you can
+automatically include the base tree information in your submission by
+using the ``--base`` flag. The easiest and most convenient way to use
+this option is with topical branches::

+ outgoing/0001-First-Commit.patch
+ outgoing/...
+
+When you open ``outgoing/0000-cover-letter.patch`` for editing, you will
+notice that it will have the ``base-commit:`` trailer at the very

+the ‘TRC’ prefix.
+
+----
+
+:File: ``mode`` (rw)
+:Trace Registers: {CONFIGR + others}
+:Notes:
+ Bit select trace features. See ‘mode’ section below. Bits
+ in this will cause equivalent programming of trace config and
+ other registers to enable the features requested.
+
+:Syntax & eg:
+ ``echo bitfield > mode``
+
+ bitfield up to 32 bits setting trace features.
+
+:Example:

+ / exclude according to the optional parameter, or if omitted
+ uses the current ‘mode’ setting. Select comparator range in
+ control register. Error if index is odd value.
+
+:Depends: ``mode, addr_idx``
+:Syntax:
+ ``echo addr1 addr2 [exclude] > addr_range``

+*Note:* When programming any address comparator the driver will tag the
+comparator with a type used - i.e. RANGE, SINGLE, START, STOP. Once this tag
+is set, then only the values can be changed using the same sysfs file / type
+used to program it.
+
+Thus::
+
+ % echo 0 > addr_idx ; select address comparator 0
+ % echo 0x1000 0x5000 0 > addr_range ; set address range on comparators 0, 1.
+ % echo 0x2000 > addr_start ; error as comparator 0 is a range comparator
+ % echo 2 > addr_idx ; select address comparator 2
+ % echo 0x2000 > addr_start ; this is OK as comparator 2 is unused.
+ % echo 0x3000 > addr_stop ; error as comparator 2 set as start address.
+ % echo 2 > addr_idx ; select address comparator 3
+ % echo 0x3000 > addr_stop ; this is OK
+
+To remove programming on all the comparators (and all the other hardware) use
+the reset parameter::
+
+ % echo 1 > reset
+
+
+
+The ‘mode’ sysfs parameter.
+---------------------------
+
+This is a bitfield selection parameter that sets the overall trace mode for the
+ETM. The table below describes the bits, using the defines from the driver
+source file, along with a description of the feature these represent. Many
+features are optional and therefore dependent on implementation in the
+hardware.
+
+Bit assignments shown below:-
+
+----
+
+**bit (0):**
+ ETM_MODE_EXCLUDE
+
+**description:**
+ This is the default value for the include / exclude function when
+ setting address ranges. Set 1 for exclude range. When the mode
+ parameter is set this value is applied to the currently indexed
+ address range.
+
+
+**bit (4):**
+ ETM_MODE_BB
+
+**description:**
+ Set to enable branch broadcast if supported in hardware [IDR0].
+
+
+**bit (5):**
+ ETMv4_MODE_CYCACC
+
+**description:**
+ Set to enable cycle accurate trace if supported [IDR0].
+
+
+**bit (6):**
+ ETMv4_MODE_CTXID
+
+**description:**
+ Set to enable context ID tracing if supported in hardware [IDR2].
+
+
+**bit (7):**
+ ETM_MODE_VMID
+
+**description:**
+ Set to enable virtual machine ID tracing if supported [IDR2].
+
+
+**bit (11):**
+ ETMv4_MODE_TIMESTAMP
+
+**description:**
+ Set to enable timestamp generation if supported [IDR0].
+
+
+**bit (12):**
+ ETM_MODE_RETURNSTACK
+**description:**
+ Set to enable trace return stack use if supported [IDR0].
+
+
+**bit (13-14):**
+ ETM_MODE_QELEM(val)
+
+**description:**
+ ‘val’ determines level of Q element support enabled if
+ implemented by the ETM [IDR0]
+
+
+**bit (19):**
+ ETM_MODE_ATB_TRIGGER
+
+**description:**
+ Set to enable the ATBTRIGGER bit in the event control register
+ [EVENTCTLR1] if supported [IDR5].
+
+
+**bit (20):**
+ ETM_MODE_LPOVERRIDE
+
+**description:**
+ Set to enable the LPOVERRIDE bit in the event control register
+ [EVENTCTLR1], if supported [IDR5].
+
+
+**bit (21):**
+ ETM_MODE_ISTALL_EN
+
+**description:**
+ Set to enable the ISTALL bit in the stall control register
+ [STALLCTLR]
+
+
+**bit (23):**
+ ETM_MODE_INSTPRIO
+
+**description:**
+ Set to enable the INSTPRIORITY bit in the stall control register
+ [STALLCTLR] , if supported [IDR0].
+
+
+**bit (24):**
+ ETM_MODE_NOOVERFLOW
+
+**description:**
+ Set to enable the NOOVERFLOW bit in the stall control register
+ [STALLCTLR], if supported [IDR3].
+
+
+**bit (25):**
+ ETM_MODE_TRACE_RESET
+
+**description:**
+ Set to enable the TRCRESET bit in the viewinst control register
+ [VICTLR] , if supported [IDR3].
+
+
+**bit (26):**
+ ETM_MODE_TRACE_ERR
+
+**description:**
+ Set to enable the TRCCTRL bit in the viewinst control register
+ [VICTLR].
+
+
+**bit (27):**
+ ETM_MODE_VIEWINST_STARTSTOP
+
+**description:**
+ Set the initial state value of the ViewInst start / stop logic
+ in the viewinst control register [VICTLR]
+
+
+**bit (30):**
+ ETM_MODE_EXCL_KERN
+
+**description:**
+ Set default trace setup to exclude kernel mode trace (see note a)
+
+
+**bit (31):**
+ ETM_MODE_EXCL_USER
+
+**description:**
+ Set default trace setup to exclude user space trace (see note a)
+
+----
+
+*Note a)* On startup the ETM is programmed to trace the complete address space
+using address range comparator 0. ‘mode’ bits 30 / 31 modify this setting to
+set EL exclude bits for NS state in either user space (EL0) or kernel space
+(EL1) in the address range comparator. (the default setting excludes all
+secure EL, and NS EL2)
+
+Once the reset parameter has been used, and/or custom programming has been
+implemented - using these bits will result in the EL bits for address
+comparator 0 being set in the same way.
+
+*Note b)* Bits 2-3, 8-10, 15-16, 18, 22, control features that only work with
+data trace. As A-profile data trace is architecturally prohibited in ETMv4,
+these have been omitted here. Possible uses could be where a kernel has
+support for control of R or M profile infrastructure as part of a heterogeneous
+system.
+
+Bits 17, 28-29 are unused.

커널 I/O 배리어의 효과
======================
-I/O 메모리에 액세스할 때, 드라이버는 적절한 액세스 함수를 사용해야 합니다:
-
- (*) inX(), outX():
-
- 이것들은 메모리 공간보다는 I/O 공간에 이야기를 하려는 의도로
- 만들어졌습니다만, 그건 기본적으로 CPU 마다 다른 컨셉입니다. i386 과
- x86_64 프로세서들은 특별한 I/O 공간 액세스 사이클과 명령어를 실제로 가지고
- 있지만, 다른 많은 CPU 들에는 그런 컨셉이 존재하지 않습니다.
-
- 다른 것들 중에서도 PCI 버스가 I/O 공간 컨셉을 정의하는데, 이는 - i386 과
- x86_64 같은 CPU 에서 - CPU 의 I/O 공간 컨셉으로 쉽게 매치됩니다. 하지만,
- 대체할 I/O 공간이 없는 CPU 에서는 CPU 의 메모리 맵의 가상 I/O 공간으로
- 매핑될 수도 있습니다.
-
- 이 공간으로의 액세스는 (i386 등에서는) 완전하게 동기화 됩니다만, 중간의
- (PCI 호스트 브리지와 같은) 브리지들은 이를 완전히 보장하진 않을수도
- 있습니다.
-
- 이것들의 상호간의 순서는 완전하게 보장됩니다.
-
- 다른 타입의 메모리 오퍼레이션, I/O 오퍼레이션에 대한 순서는 완전하게
- 보장되지는 않습니다.
+I/O 액세스를 통한 주변장치와의 통신은 아키텍쳐와 기기에 매우 종속적입니다.
+따라서, 본질적으로 이식성이 없는 드라이버는 가능한 가장 적은 오버헤드로
+동기화를 하기 위해 각자의 타겟 시스템의 특정 동작에 의존할 겁니다. 다양한
+아키텍쳐와 버스 구현에 이식성을 가지려 하는 드라이버를 위해, 커널은 다양한
+정도의 순서 보장을 제공하는 일련의 액세스 함수를 제공합니다.
(*) readX(), writeX():
- 이것들이 수행 요청되는 CPU 에서 서로에게 완전히 순서가 맞춰지고 독립적으로
- 수행되는지에 대한 보장 여부는 이들이 액세스 하는 메모리 윈도우에 정의된
- 특성에 의해 결정됩니다. 예를 들어, 최신의 i386 아키텍쳐 머신에서는 MTRR
- 레지스터로 이 특성이 조정됩니다.
+ readX() 와 writeX() MMIO 액세스 함수는 접근되는 주변장치로의 포인터를
+ __iomem * 패러미터로 받습니다. 디폴트 I/O 기능으로 매핑되는 포인터
+ (예: ioremap() 으로 반환되는 것) 의 순서 보장은 다음과 같습니다:
- 일반적으로는, 프리페치 (prefetch) 가능한 디바이스를 액세스 하는게
- 아니라면, 이것들은 완전히 순서가 맞춰지고 결합되지 않게 보장될 겁니다.
+ 1. 같은 주변장치로의 모든 readX() 와 writeX() 액세스는 각자에 대해
+ 순서지어집니다. 이는 같은 CPU 쓰레드에 의한 특정 디바이스로의 MMIO
+ 레지스터 액세스가 프로그램 순서대로 도착할 것을 보장합니다.
- 하지만, (PCI 브리지와 같은) 중간의 하드웨어는 자신이 원한다면 집행을
- 연기시킬 수 있습니다; 스토어 명령을 실제로 하드웨어로 내려보내기(flush)
- 위해서는 같은 위치로부터 로드를 하는 방법이 있습니다만[*], PCI 의 경우는
- 같은 디바이스나 환경 구성 영역에서의 로드만으로도 충분할 겁니다.
+ 2. 한 스핀락을 잡은 CPU 쓰레드에 의한 writeX() 는 같은 스핀락을 나중에
+ 잡은 다른 CPU 쓰레드에 의해 같은 주변장치를 향해 호출된 writeX()
+ 앞으로 순서지어집니다. 이는 스핀락을 잡은 채 특정 디바이스를 향해
+ 호출된 MMIO 레지스터 쓰기는 해당 락의 획득에 일관적인 순서로 도달할
+ 것을 보장합니다.
- [*] 주의! 쓰여진 것과 같은 위치로부터의 로드를 시도하는 것은 오동작을
- 일으킬 수도 있습니다 - 예로 16650 Rx/Tx 시리얼 레지스터를 생각해
- 보세요.
+ 3. 특정 주변장치를 향한 특정 CPU 쓰레드의 writeX() 는 먼저 해당
+ 쓰레드로 전파되는, 또는 해당 쓰레드에 의해 요청된 모든 앞선 메모리
+ 쓰기가 완료되기 전까지 먼저 기다립니다. 이는 dma_alloc_coherent()
+ 를 통해 할당된 전송용 DMA 버퍼로의 해당 CPU 의 쓰기가 이 CPU 가 이
+ 전송을 시작시키기 위해 MMIO 컨트롤 레지스터에 쓰기를 할 때 DMA
+ 엔진에 보여질 것을 보장합니다.
- 프리페치 가능한 I/O 메모리가 사용되면, 스토어 명령들이 순서를 지키도록
- 하기 위해 mmiowb() 배리어가 필요할 수 있습니다.
+ 4. 특정 CPU 쓰레드에 의한 주변장치로의 readX() 는 같은 쓰레드에 의한
+ 모든 뒤따르는 메모리 읽기가 시작되기 전에 완료됩니다. 이는
+ dma_alloc_coherent() 를 통해 할당된 수신용 DMA 버퍼로부터의 CPU 의
+ 읽기는 이 DMA 수신의 완료를 표시하는 DMA 엔진의 MMIO 상태 레지스터
+ 읽기 후에는 오염된 데이터를 읽지 않을 것을 보장합니다.
- PCI 트랜잭션 사이의 상호작용에 대해 더 많은 정보를 위해선 PCI 명세서를
- 참고하시기 바랍니다.
+ 5. CPU 에 의한 주변장치로의 readX() 는 모든 뒤따르는 delay() 루프가
+ 수행을 시작하기 전에 완료됩니다. 이는 CPU 의 특정
+ 주변장치로의 두개의 MMIO 레지스터 쓰기가 행해지는데 첫번째 쓰기가
+ readX() 를 통해 곧바로 읽어졌고 이어 두번째 writeX() 전에 udelay(1)
+ 이 호출되었다면 이 두개의 쓰기는 최소 1us 의 간격을 두고 행해질 것을
+ 보장합니다:
+
+ writel(42, DEVICE_REGISTER_0); // 디바이스에 도착함...
+ readl(DEVICE_REGISTER_0);
+ udelay(1);
+ writel(42, DEVICE_REGISTER_1); // ...이것보다 최소 1us 전에.
+
+ 디폴트가 아닌 기능을 통해 얻어지는 __iomem 포인터 (예: ioremap_wc() 를
+ 통해 리턴되는 것) 의 순서 속성은 실제 아키텍쳐에 의존적이어서 이런
+ 종류의 매핑으로의 액세스는 앞서 설명된 보장사항에 의존할 수 없습니다.
(*) readX_relaxed(), writeX_relaxed()
- 이것들은 readX() 와 writeX() 랑 비슷하지만, 더 완화된 메모리 순서 보장을
- 제공합니다. 구체적으로, 이것들은 일반적 메모리 액세스 (예: DMA 버퍼) 에도
- LOCK 이나 UNLOCK 오퍼레이션들에도 순서를 보장하지 않습니다. LOCK 이나
- UNLOCK 오퍼레이션들에 맞춰지는 순서가 필요하다면, mmiowb() 배리어가 사용될
- 수 있습니다. 같은 주변 장치에의 완화된 액세스끼리는 순서가 지켜짐을 알아
- 두시기 바랍니다.
+ 이것들은 readX() 와 writeX() 랑 비슷하지만, 더 완화된 메모리 순서

+ 기능으로 매핑된 __iomem 포인터에 대해 동작할 때, 같은 CPU 쓰레드에 의해
+ 같은 주변장치로의 액세스에는 순서가 맞춰질 것이 보장됩니다.
+
+ (*) readsX(), writesX():
+
+ readsX() 와 writesX() MMIO 액세스 함수는 DMA 를 수행하는데 적절치 않은,
+ 주변장치 내의 메모리 매핑된 레지스터 기반 FIFO 로의 액세스를 위해
+ 설계되었습니다. 따라서, 이 기능들은 앞서 설명된 readX_relaxed() 와
+ writeX_relaxed() 의 순서 보장만을 제공합니다.
+
+ (*) inX(), outX():
+
+ inX() 와 outX() 액세스 함수는 일부 아키텍쳐 (특히 x86) 에서는 특수한
+ 명령어를 필요로 하며 포트에 매핑되는, 과거의 유산인 I/O 주변장치로의
+ 접근을 위해 만들어졌습니다.
+
+ 많은 CPU 아키텍쳐가 결국은 이런 주변장치를 내부의 가상 메모리 매핑을
+ 통해 접근하기 때문에, inX() 와 outX() 가 제공하는 이식성 있는 순서
+ 보장은 디폴트 I/O 기능을 통한 매핑을 접근할 때의 readX() 와 writeX() 에
+ 의해 제공되는 것과 각각 동일합니다.
+
+ 디바이스 드라이버는 outX() 가 리턴하기 전에 해당 I/O 주변장치로부터의
+ 완료 응답을 기다리는 쓰기 트랜잭션을 만들어 낸다고 기대할 수도
+ 있습니다. 이는 모든 아키텍쳐에서 보장되지는 않고, 따라서 이식성 있는
+ 순서 규칙의 일부분이 아닙니다.
+
+ (*) insX(), outsX():
+
+ 앞에서와 같이, insX() 와 outsX() 액세스 함수는 디폴트 I/O 기능을 통한
+ 매핑을 접근할 때 각각 readX() 와 writeX() 와 같은 순서 보장을
+ 제공합니다.
(*) ioreadX(), iowriteX()
- 이것들은 inX()/outX() 나 readX()/writeX() 처럼 실제로 수행하는 액세스의
- 종류에 따라 적절하게 수행될 것입니다.
+ 이것들은 inX()/outX() 나 readX()/writeX() 처럼 실제로 수행하는 액세스의
+ 종류에 따라 적절하게 수행될 것입니다.
+
+String 액세스 함수 (insX(), outsX(), readsX() 그리고 writesX()) 의 예외를
+제외하고는, 앞의 모든 것이 아랫단의 주변장치가 little-endian 이라 가정하며,
+따라서 big-endian 아키텍쳐에서는 byte-swapping 오퍼레이션을 수행합니다.

+ * Notes on locking
+ *
+ * kvm->arch.uvmem_lock is a per-guest lock that prevents concurrent
+ * page-in and page-out requests for the same GPA. Concurrent accesses
+ * can either come via UV (guest vCPUs requesting for same page)
+ * or when HV and guest simultaneously access the same page.
+ * This mutex serializes the migration of page from HV(normal) to
+ * UV(secure) and vice versa. So the serialization points are around
+ * migrate_vma routines and page-in/out routines.
+ *
+ * Per-guest mutex comes with a cost though. Mainly it serializes the
+ * fault path as page-out can occur when HV faults on accessing secure
+ * guest pages. Currently UV issues page-in requests for all the guest
+ * PFNs one at a time during early boot (UV_ESM uvcall), so this is
+ * not a cause for concern. Also currently the number of page-outs caused
+ * by HV touching secure pages is very very low. If an when UV supports
+ * overcommitting, then we might see concurrent guest driven page-outs.

+ * Notes on page size
+ *
+ * Currently UV uses 2MB mappings internally, but will issue H_SVM_PAGE_IN
+ * and H_SVM_PAGE_OUT hcalls in PAGE_SIZE(64K) granularity. HV tracks
+ * secure GPAs at 64K page size and maintains one device PFN for each
+ * 64K secure GPA. UV_PAGE_IN and UV_PAGE_OUT calls by HV are also issued
+ * for 64K page at a time.
+ *
+ * HV faulting on secure pages: When HV touches any secure page, it
+ * faults and issues a UV_PAGE_OUT request with 64K page size. Currently
+ * UV splits and remaps the 2MB page if necessary and copies out the
+ * required 64K page contents.
+ *
+ * Shared pages: Whenever guest shares a secure page, UV will split and
+ * remap the 2MB page if required and issue H_SVM_PAGE_IN with 64K page size.
+ *
+ * HV invalidating a page: When a regular page belonging to secure
+ * guest gets unmapped, HV informs UV with UV_PAGE_INVAL of 64K
+ * page size. Using 64K page size is correct here because any non-secure
+ * page will essentially be of 64K page size. Splitting by UV during sharing
+ * and page-out ensures this.
+ *
+ * Page fault handling: When HV handles page fault of a page belonging
+ * to secure guest, it sends that to UV with a 64K UV_PAGE_IN request.
+ * Using 64K size is correct here too as UV would have split the 2MB page
+ * into 64k mappings and would have done page-outs earlier.
+ *
+ * In summary, the current secure pages handling code in HV assumes
+ * 64K page size and in fact fails any page-in/page-out requests of
+ * non-64K size upfront. If and when UV starts supporting multiple
+ * page-sizes, we need to break this assumption.

+ * freed. Otherwise, outstanding IOASIDs will be lost and orphaned.
+ * 4. When switching between custom allocators sharing the same helper

+ *
+ * When cfg_irq_numa is enabled, the adapter will only allocate vectors for

+ * affinity will be set to the nearest peer cpu within the numa node that is
+ * online. If there are no online cpus within the numa node, affinity is not
+ * assigned and the OS may do as it pleases. Note: cpu vector affinity mapping
+ * is consistent with the way cpu online/offline is handled when cfg_irq_numa is
+ * configured.
+ *
+ * If numa mode is not enabled and there is more than 1 vector allocated, then

+ * used for coverage collection. A userspace process passes this handle to

+ *
+ * The usage of these annotations in the kernel code is different depending on
+ * the type of the kernel thread whose code is being annotated.
+ *
+ * For global kernel threads that are spawned in a limited number of instances
+ * (e.g. one USB hub_event() worker thread is spawned per USB HCD), each
+ * instance must be assigned a unique 4-byte instance id. The instance id is
+ * then combined with a 1-byte subsystem id to get a handle via
+ * kcov_remote_handle(subsystem_id, instance_id).
+ *
+ * For local kernel threads that are spawned from system calls handler when a
+ * user interacts with some kernel interface (e.g. vhost workers), a handle is
+ * passed from a userspace process as the common_handle field of the
+ * kcov_remote_arg struct (note, that the user must generate a handle by using
+ * kcov_remote_handle() with KCOV_SUBSYSTEM_COMMON as the subsystem id and an
+ * arbitrary 4-byte non-zero number as the instance id). This common handle
+ * then gets saved into the task_struct of the process that issued the
+ * KCOV_REMOTE_ENABLE ioctl. When this proccess issues system calls that spawn
+ * kernel threads, the common handle must be retrived via kcov_common_handle()
+ * and passed to the spawned threads via custom annotations. Those kernel
+ * threads must in turn be annotated with kcov_remote_start(common_handle) and
+ * kcov_remote_stop(). All of the threads that are spawned by the same process
+ * obtain the same handle, hence the name "common".

+ * under vmap_area_lock, so it's not safe to interact with the vmalloc/vmap
+ * infrastructure.
+ *
+ * How does this work?
+ * -------------------
+ *
+ * We have a region that is page aligned, labelled as A.
+ * That might not map onto the shadow in a way that is page-aligned:
+ *
+ * start end
+ * v v
+ * |????????|????????|AAAAAAAA|AA....AA|AAAAAAAA|????????| < vmalloc
+ * -------- -------- -------- -------- --------
+ * | | | | |
+ * | | | /-------/ |
+ * \-------\|/------/ |/---------------/
+ * ||| ||
+ * |??AAAAAA|AAAAAAAA|AA??????| < shadow
+ * (1) (2) (3)
+ *
+ * First we align the start upwards and the end downwards, so that the
+ * shadow of the region aligns with shadow page boundaries. In the
+ * example, this gives us the shadow page (2). This is the shadow entirely
+ * covered by this allocation.
+ *
+ * Then we have the tricky bits. We want to know if we can free the
+ * partially covered shadow pages - (1) and (3) in the example. For this,
+ * we are given the start and end of the free region that contains this
+ * allocation. Extending our previous example, we could have:
+ *
+ * free_region_start free_region_end
+ * | start end |
+ * v v v v
+ * |FFFFFFFF|FFFFFFFF|AAAAAAAA|AA....AA|AAAAAAAA|FFFFFFFF| < vmalloc
+ * -------- -------- -------- -------- --------
+ * | | | | |
+ * | | | /-------/ |
+ * \-------\|/------/ |/---------------/
+ * ||| ||
+ * |FFAAAAAA|AAAAAAAA|AAF?????| < shadow
+ * (1) (2) (3)
+ *
+ * Once again, we align the start of the free region up, and the end of
+ * the free region down so that the shadow is page aligned. So we can free
+ * page (1) - we know no allocation currently uses anything in that page,
+ * because all of it is in the vmalloc free region. But we cannot free
+ * page (3), because we can't be sure that the rest of it is unused.
+ *
+ * We only consider pages that contain part of the original region for
+ * freeing: we don't try to free other pages from the free region or we'd
+ * end up trying to free huge chunks of virtual address space.
+ *
+ * Concurrency
+ * -----------
+ *
+ * How do we know that we're not freeing a page that is simultaneously
+ * being used for a fresh allocation in kasan_populate_vmalloc(_pte)?
+ *
+ * We _can_ have kasan_release_vmalloc and kasan_populate_vmalloc running
+ * at the same time. While we run under free_vmap_area_lock, the population
+ * code does not.
+ *
+ * free_vmap_area_lock instead operates to ensure that the larger range
+ * [free_region_start, free_region_end) is safe: because __alloc_vmap_area and
+ * the per-cpu region-finding algorithm both run under free_vmap_area_lock,
+ * no space identified as free will become used while we are running. This
+ * means that so long as we are careful with alignment and only free shadow
+ * pages entirely covered by the free region, we will not run in to any
+ * trouble - any simultaneous allocations will be for disjoint regions.
