Realtek MIPS SoCs (platform name Otto) have a watchdog timer with
pretimeout notifitication support. The WDT can (partially) hard reset,
or soft reset the SoC.
This driver implements all features as described in the devicetree
binding, except the phase2 interrupt, and also functions as a restart
handler. The cpu reset mode is considered to be a "warm" restart, since
this mode does not reset all peripherals. Being an embedded system
though, the "cpu" and "software" modes will still cause the bootloader
to run on restart.
It is not known how a forced system reset can be disabled on the
supported platforms. This means that the phase2 interrupt will only fire
at the same time as reset, so implementing phase2 is of little use.

This driver implements monitoring and control of fans plugged into the
device. Besides typical speed monitoring and PWM duty cycle control,
voltage and current are reported for every fan.
The device also has 2 connectors for RGB LEDs, support for them isn't
implemented (mainly because there is no standardized sysfs interface).
Also, the device has a noise sensor, but the sensor seems to be completely
useless (and very imprecise), so support for it isn't implemented too.
The driver coexists with userspace tools that access the device through
hidraw interface with no known issues.
The driver has been tested on x86_64, built in and as a module.
Some changes/improvements were suggested by Jonas Malaco.

Linux HWMON sensors driver for ASUS motherboards to read
sensors from the embedded controller.
Many ASUS motherboards do not publish all the available
sensors via the Super I/O chip but the missing ones are
available through the embedded controller (EC) registers.
This driver implements reading those sensor data via the
WMI method BREC, which is known to be present in all ASUS
motherboards based on the AMD 500 series chipsets (and
probably is available in other models too). The driver
needs to know exact register addresses for the sensors and
thus support for each motherboard has to be added explicitly.
The EC registers do not provide critical values for the
sensors and as such they are not published to the HWMON.
Supported motherboards:
* PRIME X570-PRO
* Pro WS X570-ACE
* ROG CROSSHAIR VIII HERO
* ROG CROSSHAIR VIII DARK HERO
* ROG CROSSHAIR VIII FORMULA
* ROG STRIX X570-E GAMING
* ROG STRIX B550-I GAMING
* ROG STRIX B550-E GAMING

x86 tablets which ship with Android as (part of) the factory image
typically have various problems with their DSDTs. The factory kernels
shipped on these devices typically have device addresses and GPIOs
hardcoded in the kernel, rather then specified in their DSDT.
With the DSDT containing a random collection of devices which may or
may not actually be present as well as missing devices which are
actually present.
This driver, which loads only on affected models based on DMI matching,
adds DMI based instantiating of kernel devices for devices which are
missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or
accelerometers not working.
Note the Kconfig help text also refers to "various fixes" ATM there are
no such fixes, but there are also known cases where entries are present
in the DSDT but they contain bugs, such as missing/wrong GPIOs. The plan
is to also add fixes for things like this here in the future.
This is the least ugly option to get these devices to fully work and to
do so without adding any extra code to the main kernel image (vmlinuz)
when built as a module.

Intel Platform Monitoring Technology (PMT) support is indicated by presence
of an Intel defined PCIe Designated Vendor Specific Extended Capabilities
(DVSEC) structure with a PMT specific ID. The current MFD implementation
creates child devices for each PMT feature, currently telemetry, watcher,
and crashlog. However DVSEC structures may also be used by Intel to
indicate support for other features. The Out Of Band Management Services
Module (OOBMSM) uses DVSEC to enumerate several features, including PMT.
In order to support them it is necessary to modify the intel_pmt driver to
handle the creation of the child devices more generically. To that end,
modify the driver to create child devices for any VSEC/DVSEC features on
supported devices (indicated by PCI ID). Additionally, move the
implementation from MFD to the Auxiliary bus. VSEC/DVSEC features are
really multifunctional PCI devices, not platform devices as MFD was
designed for. Auxiliary bus gives more flexibility by allowing the
definition of custom structures that can be shared between associated
auxiliary devices and the parent device. Also, rename the driver from
intel_pmt to intel_vsec to better reflect the purpose.
This series also removes the current runtime pm support which was not
complete to begin with. None of the current devices require runtime pm.
However the support will be replaced when a device is added that requires
it.

Includes some fixes that were either late breaking, low priority or
complex enough to not be good to rush in late in the cycle.
Tree rebased today to fix up some trivial issues + pull in a fix that
was previously on the fixes-togreg branch. Vast majority have been
in linux-next for some time now.
New device support
* adi,ad7293
- New driver and bindings for this Power Amplifier drain current
controller. A complex device with various related monitoring functions.
* adi,ad75513R
- New driver and bindings for this combined ADC and DAC device.
- A few follow up fixes.
* adi,admv8818
- New driver (and type) for this 2-18GHz filter device. Includes
bindings and ABI documentation to allow clk_notifier based auto
adjustment of the filters in appropriate applications.
* liteon,ltr501
- Support for the ltr303. ID and chip specific info table.
* xilinx,ams
- New generic firmware function fwnode_iomap() as used in this driver.
- New driver and bindings for this ADC and on-chip sensors as found
in various Xilinx devices.
Core
* Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to
form a 64 bit integer when higher precision needed.
* Allow IIO_ENUM_AVAILABLE to be used with different shared values.
* Fix a long term issue with scheduling whilst atomic when iio_trig_poll()
is called but no trigger consumers are actually enabled and hence the
trigger may be reenabled from the interrupt handler. Seen in the wild
on the tsc2046.
* Mark iio_device_type const.
* buffer: Use a separate index variable to simplify code.
* buffer-dma: Clear out unused struct iio_buffer_block
* buffer-dmaengine: Switch to cheaper round_down() as power of 2 values.
Tests/tools
* format_value
- Check against NULL returns from allocations in tests.
- Add IIO_VAL_INT_64 test case.
* event_monitor
- Flush the output after event to given more consistent latency
when tool output piped to other programs.
Driver Features
* axp20x
- Add support for NTC thermistor channel and document TS pin binding.
* arm,scmi
- Add reading of raw channel values (using IIO_VAL_INT_64)
* liteon,ltr501
- Add proximity-near-level support and dt-binding.
Tree wide cleanup
* Remove no-op trigger ops from multiple drivers.
* Stop using dev_get_drvdata() on the iio_dev->dev in various drivers
and then stop assigning it to allow this to be used for other purposes.
We can always get to the indio_dev using dev_to_iio_dev() which is
a container_of() based approach. Also cleanup up some related unnecessary

1st set of IIO new device support, features and cleanup for 5.17
Includes some fixes that were either late breaking, low priority or
complex enough to not be good to rush in late in the cycle.
Tree rebased today to fix up some trivial issues + pull in a fix that
was previously on the fixes-togreg branch. Vast majority have been
in linux-next for some time now.
New device support
* adi,ad7293
- New driver and bindings for this Power Amplifier drain current
controller. A complex device with various related monitoring functions.
* adi,ad75513R
- New driver and bindings for this combined ADC and DAC device.
- A few follow up fixes.
* adi,admv8818
- New driver (and type) for this 2-18GHz filter device. Includes
bindings and ABI documentation to allow clk_notifier based auto
adjustment of the filters in appropriate applications.
* liteon,ltr501
- Support for the ltr303. ID and chip specific info table.
* xilinx,ams
- New generic firmware function fwnode_iomap() as used in this driver.
- New driver and bindings for this ADC and on-chip sensors as found
in various Xilinx devices.
Core
* Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to
form a 64 bit integer when higher precision needed.
* Allow IIO_ENUM_AVAILABLE to be used with different shared values.
* Fix a long term issue with scheduling whilst atomic when iio_trig_poll()
is called but no trigger consumers are actually enabled and hence the
trigger may be reenabled from the interrupt handler. Seen in the wild
on the tsc2046.
* Mark iio_device_type const.
* buffer: Use a separate index variable to simplify code.
* buffer-dma: Clear out unused struct iio_buffer_block
* buffer-dmaengine: Switch to cheaper round_down() as power of 2 values.
Tests/tools
* format_value
- Check against NULL returns from allocations in tests.
- Add IIO_VAL_INT_64 test case.
* event_monitor
- Flush the output after event to given more consistent latency
when tool output piped to other programs.
Driver Features
* axp20x
- Add support for NTC thermistor channel and document TS pin binding.
* arm,scmi
- Add reading of raw channel values (using IIO_VAL_INT_64)
* liteon,ltr501
- Add proximity-near-level support and dt-binding.
Tree wide cleanup
* Remove no-op trigger ops from multiple drivers.
* Stop using dev_get_drvdata() on the iio_dev->dev in various drivers
and then stop assigning it to allow this to be used for other purposes.
We can always get to the indio_dev using dev_to_iio_dev() which is
a container_of() based approach. Also cleanup up some related unnecessary
convoluted cases.
- atmel,at91-sam5d2
- nxp,imx7d
- meas,ms5611
- st,st_sensors
* Where available (or easy to introduce) use the scan_type.* values
in place of a second copy for read_raw and similar paths.
- adi,ad7266
- bosch,bma220
- fsl,mac3110
- fsl,mma7455
- fsl,mpl3115
- kionix,kcjk-1013
- sensortek,stk8ba50
- sensortek,stk8312
- ti,adc12138
- ti,ads1015
- vti,sca3000
- xilinx,xadc-core
* Switch drives over to generic firmware properties including appropriate
header changes to avoid including of.h
- Various DACs had false CONFIG_OF dependencies.
- dpot-dac
- envelope-detector
- adi,ad5755
- adi,ad5758
- capella,cm3605
- maxim,max9611

1. Exynos ChipID: add Exynos7885 support.
2. Exynos PMU: add Exynos850 support.
3. Minor bindings cleanup.
4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
a shared IP block between I2C, UART/serial and SPI. Basically one has
to choose which feature the USI block will support and later the
regular I2C/serial/SPI driver will bind and work.
This merges also one commit with dt-binding headers from my dts64
pull request.
Together with a future serial driver change, this will break the ABI.
Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards
Why: To properly and efficiently support the USI with new hierarchy
of USI-{serial,SPI,I2C} devicetree nodes.
Rationale:
Recently added serial and USI support was short-sighted and did not
allow to smooth support of other features (SPI and I2C). Adding
support for USI-SPI and USI-I2C would effect in code duplication.
Adding support for different USI versions (currently supported is
USIv2 but support for v1 is planned) would cause even more code
duplication and create a solution difficult to maintain.
Since USI-serial and ExynosAutov9 have been added recently, are
considered fresh development features and there are no supported
products using them, the code/solution is being refactored in
non-backwards compatible way. The compatibility is not broken yet.
It will be when serial driver changes are accepted.
The ABI break was discussed with only known users of ExynosAutov9 and
received their permission.

The MSC313e-compatible SoCs have 3 timer hardware blocks. All of these
are free running 32-bit increasing counters and can generate interrupts.
Based onto a maximum value register, each timer can either count from 0
to max, one time then stop (which generates interrupts) or can count
from 0 to max and then roll. This commit adds basic support for these
timers, the first timer block being used as clocksource/sched_clock
and delay, while the others will be used as clockevents.

This adds support for the StarFive JH7100 RISC-V SoC. The SoC has many
devices that need non-coherent DMA operations to work which isn't
upstream yet[1], so this just adds basic support to boot up, get a
serial console, blink an LED and reboot itself. Unlike the Allwinner D1
this chip doesn't use any extra pagetable bits, but instead the DDR RAM
appears twice in the memory map, with and without the cache.
The JH7100 is a test chip for the upcoming JH7110 and about 300 BeagleV
Starlight Beta boards were sent out with them as part of a now cancelled
BeagleBoard.org project. However StarFive has produced more of the
JH7100s and will be selling VisionFive boards with them soon[2].

Add a combined pinctrl and GPIO driver for the JH7100 RISC-V SoC by
StarFive Ltd. This is a test chip for their upcoming JH7110 SoC, which
is said to feature only minor changes to these pinctrl/GPIO parts.
For each "GPIO" there are two registers for configuring the output and
output enable signals which may come from other peripherals. Among these
are two special signals that are constant 0 and constant 1 respectively.
Controlling the GPIOs from software is done by choosing one of these
signals. In other words the same registers are used for both pin muxing
and controlling the GPIOs, which makes it easier to combine the pinctrl
and GPIO driver in one.
I wrote the pinconf and pinmux parts, but the GPIO part of the code is
based on the GPIO driver in the vendor tree written by Huan Feng with
cleanups and fixes by Drew and me.

PCIe PMU Root Complex Integrated End Point(RCiEP) device is supported
to sample bandwidth, latency, buffer occupation etc.
Each PMU RCiEP device monitors multiple Root Ports, and each RCiEP is
registered as a PMU in /sys/bus/event_source/devices, so users can
select target PMU, and use filter to do further sets.
Filtering options contains:
event - select the event.
port - select target Root Ports. Information of Root Ports are
shown under sysfs.
bdf - select requester_id of target EP device.
trig_len - set trigger condition for starting event statistics.
trig_mode - set trigger mode. 0 means starting to statistic when bigger
than trigger condition, and 1 means smaller.
thr_len - set threshold for statistics.
thr_mode - set threshold mode. 0 means count when bigger than threshold,
and 1 means smaller.

The AD74412R and AD74413R are quad-channel, software configurable,
input/output solutions for building and process control applications.
They contain functionality for analog output, analog input, digital input,
resistance temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.
The devices feature a 16-bit ADC and four configurable 13-bit DACs to
provide four configurable input/output channels and a suite of diagnostic
functions.
The AD74413R differentiates itself from the AD74412R by being
HART-compatible.
When configured with channel 0 as voltage output, channel 1 as current
output, channel 2 as voltage input and channel 3 as current input, the
following structure is created under the corresponding IIO device.

Add a basic test for the mixer control interface. For every control on
every sound card in the system it checks that it can read and write the
default value where the control supports that and for writeable controls
attempts to write all valid values, restoring the default values after
each test to minimise disruption for users.
There are quite a few areas for improvement - currently no coverage of the
generation of notifications, several of the control types don't have any
coverage for the values and we don't have any testing of error handling
when we attempt to write out of range values - but this provides some basic
coverage.
This is added as a kselftest since unlike other ALSA test programs it does
not require either physical setup of the device or interactive monitoring
by users and kselftest is one of the test suites that is frequently run by
people doing general automated testing so should increase coverage. It is
written in terms of alsa-lib since tinyalsa is not generally packaged for
distributions which makes things harder for general users interested in
kselftest as a whole but it will be a barrier to people with Android.

- vgacon fix for reported problem
All of these, except for the 8250_bcm7271 fix have been in linux-next
with no reported problem. The 8250_bcm7271 fix was added to the tree on
Friday so no chance to be linux-next yet. But it should be fine as the

Xilinx event management driver provides an interface to subscribe or
unsubscribe for the event/callback supported by firmware. An agent can use
this driver to register for Error Event, Device Event and Suspend callback.
This driver only allows one agent per event to do registration. Driver will
return an error in case of multiple registration for the same event.
This driver gets notification from firmware through TF-A as SGI. During
initialization, event manager driver register handler for SGI used for
notification. It also provides SGI number info to TF-A by using
IOCTL_REGISTER_SGI call to TF-A.
After receiving notification from firmware, the driver makes an SMC call to
TF-A to get IPI data. From the IPI data provided by TF-A, event manager
identified the cause of event and forward that event/callback notification
to the respective subscribed driver. After this, in case of Error Event,
driver performs unregistration as firmware expecting from agent to do
re-registration if the agent wants to get notified on the second occurrence
of an error event.
Add new IOCTL id IOCTL_REGISTER_SGI = 25 which is used to register SGI on
TF-A.
Older firmware doesn't have all required support for event handling which
is required by the event manager driver. So add check for the register
notifier version in the event manager driver.
Xilinx event management driver provides support to subscribe for multiple
error events with the use of Event Mask in a single call of
xlnx_register_event(). Agent driver can provide 'Event' parameter value as
ORed of multiple event masks to register single callback for multiple
events. For example, to register callback for event=0x1 and event=0x2 for
the given node, agent can provide event=0x3 (0x1 | 0x2). It is not possible
to register multiple events for different nodes in a single registration
call.
Also provide support to receive multiple error events as in single
notification from firmware and then forward it to subscribed drivers via
registered callback one by one.

Most SoC specific clock drivers are picked by respective SoC maintainer
and then sent to the clock maintainers on their way upstream.
This has however not been the case for the Qualcomm clock drivers -
which doesn't actually have a maintainer per MAINTAINERS and where the
framework maintainers have just carried the Qualcomm effort as well,
presumably as a result of Stephen's history.
Move the maintainership of the Qualcomm clock drivers to use the same
model as other SoC vendors and document the ownership by actually
introducing an entry in MAINTAINERS.

The OV5693 is a 5 Mpx CMOS image sensor, connected via MIPI CSI-2. The
chip is capable of a single lane configuration, but currently only two
lanes are supported.
Most of the sensor's features are supported, with the main exception
being the lens correction algorithm.
The driver provides all mandatory, optional and recommended V4L2 controls
for maximum compatibility with libcamera.

Device Tree bindings.
Fixing it with the simples set of docs now:
1. Overview with pointers to other informational resources
2. Autogenerated feature table
Note though it's just the very beginning, there will be more
for sure given time as there're many things worth documenting
and in fact even contents itself is avaialble but just spread
in some other places. Now we'll try to keep all here and
then maintain it looking forward to match the state of development.

The BAM Data Multiplexer provides access to the network data channels of
modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or
MSM8974. It is built using a simple protocol layer on top of a DMA engine
(Qualcomm BAM) and bidirectional interrupts to coordinate power control.
The modem announces a fixed set of channels by sending an OPEN command.
The driver exports each channel as separate network interface so that
a connection can be established via QMI from userspace. The network
interface can work either in Ethernet or Raw-IP mode (configurable via
QMI). However, Ethernet mode seems to be broken with most firmwares
(network packets are actually received as Raw-IP), therefore the driver
only supports Raw-IP mode.
Note that the control channel (QMI/AT) is entirely separate from
BAM-DMUX and is already supported by the RPMSG_WWAN_CTRL driver.
The driver uses runtime PM to coordinate power control with the modem.
TX/RX buffers are put in a kind of "ring queue" and submitted via
the bam_dma driver of the DMAEngine subsystem.
The basic architecture looks roughly like this:
+------------+ +-------+
[IPv4/6] | BAM-DMUX | | |
[Data...] | | | |
---------->|wwan0 | [DMUX chan: x] | |
[IPv4/6] | (chan: 0) | [IPv4/6] | |
[Data...] | | [Data...] | |
---------->|wwan1 |--------------->| Modem |
| (chan: 1) | BAM | |
[IPv4/6] | ... | (DMA Engine) | |
[Data...] | | | |
---------->|wwan7 | | |
| (chan: 7) | | |
+------------+ +-------+
Note that some newer firmware versions support QMAP ("rmnet" driver)
as additional multiplexing layer on top of BAM-DMUX, but this is not
currently supported by this driver.

- Add missing Kconfig option for ftrace direct multi sample, so it can
be compiled again, and also add s390 support for this sample.
- Update Christian Borntraeger's email address.
- Various fixes for memory layout setup. Besides other this makes it
possible to load shared DCSS segments again.
- Fix copy to user space of swapped kdump oldmem.
- Remove -mstack-guard and -mstack-size compile options when building
vdso binaries. This can happen when CONFIG_VMAP_STACK is disabled
and results in broken vdso code which causes more or less random
exceptions. Also remove the not needed -nostdlib option.
- Fix memory leak on cpu hotplug and return code handling in kexec
code.
- Wire up futex_waitv system call.
- Replace snprintf with sysfs_emit where appropriate.

Driver") only adds drivers/crypto/keembay/keembay-ocs-ecc.c, but adds a
file entry drivers/crypto/keembay/ocs-ecc-curve-defs.h in MAINTAINERS.
Hence, ./scripts/get_maintainer.pl --self-test=patterns warns:
warning: no file matches F: drivers/crypto/keembay/ocs-ecc-curve-defs.h
Assuming that this header is obsolete and will not be included in the

IB/hfi1: Properly allocate rdma counter desc memory
RDMA/core: Set send and receive CQ before forwarding to the driver

Currently, I have to use a separate email address and maintain several
filters to monitor changes to Logitech drivers, so that I can have an
opportunity to review them. Since I am very interested in keeping up
with the changes, as I have a lot of the hardware and maintain the main
userspace stacks that depend on these drivers, I would like to mark
myself as a reviewer. I would also be open to be marked as a maintainer
if Benjamin thinks it makes sense.

Replace the old .txt binding with a new schema binding.
At the same time, some of the descriptions are updated to make them
clearer, fix errors, or just make them fit better into the style
of schema binding.
The cirrus,hs-bias-ramp-rate property was missing from the old .txt
binding and has been added to the yaml.

Using these features the driver is able to act as a 1080p @ 30 fps V4L2
video source. Producing either a checkerboard or gradient pattern on the
CSI-2 bus, selectable thru a V4L2 control.
While the driver is useful as-is and have been used to prove the correct
operation of the MAX96712 itself and "downstream" devices using the
MAX96712 as a video source there are a lot of features missing. Most
notably the ability to operate the GMSL bus.

This PR includes 5 commits that update the zstd library version:
1. Adds a new kernel-style wrapper around zstd. This wrapper API
is functionally equivalent to the subset of the current zstd API that is
currently used. The wrapper API changes to be kernel style so that the symbols
don't collide with zstd's symbols. The update to zstd-1.4.10 maintains the same
API and preserves the semantics, so that none of the callers need to be
updated. All callers are updated in the commit, because there are zero
functional changes.
2. Adds an indirection for `lib/decompress_unzstd.c` so it
doesn't depend on the layout of `lib/zstd/` to include every source file.
This allows the next patch to be automatically generated.
3. Imports the zstd-1.4.10 source code. This commit is automatically generated
from upstream zstd (https://github.com/facebook/zstd).
4. Adds me (terrelln@fb.com) as the maintainer of `lib/zstd`.
5. Fixes a newly added build warning for clang.
The discussion around this patchset has been pretty long, so I've included a
FAQ-style summary of the history of the patchset, and why we are taking this
approach.
Why do we need to update?
-------------------------
The zstd version in the kernel is based off of zstd-1.3.1, which is was released
August 20, 2017. Since then zstd has seen many bug fixes and performance
improvements. And, importantly, upstream zstd is continuously fuzzed by OSS-Fuzz,
and bug fixes aren't backported to older versions. So the only way to sanely get
these fixes is to keep up to date with upstream zstd. There are no known security
issues that affect the kernel, but we need to be able to update in case there
are. And while there are no known security issues, there are relevant bug fixes.
For example the problem with large kernel decompression has been fixed upstream
for over 2 years https://lkml.org/lkml/2020/9/29/27.
Additionally the performance improvements for kernel use cases are significant.
Measured for x86_64 on my Intel i9-9900k @ 3.6 GHz:
- BtrFS zstd compression at levels 1 and 3 is 5% faster
- BtrFS zstd decompression+read is 15% faster
- SquashFS zstd decompression+read is 15% faster
- F2FS zstd compression+write at level 3 is 8% faster
- F2FS zstd decompression+read is 20% faster
- ZRAM decompression+read is 30% faster
- Kernel zstd decompression is 35% faster
- Initramfs zstd decompression+build is 5% faster
On top of this, there are significant performance improvements coming down the
line in the next zstd release, and the new automated update patch generation
will allow us to pull them easily.
How is the update patch generated?
----------------------------------
The first two patches are preparation for updating the zstd version. Then the
3rd patch in the series imports upstream zstd into the kernel. This patch is
automatically generated from upstream. A script makes the necessary changes and
imports it into the kernel. The changes are:
- Replace all libc dependencies with kernel replacements and rewrite includes.
- Remove unncessary portability macros like: #if defined(_MSC_VER).
- Use the kernel xxhash instead of bundling it.
This automation gets tested every commit by upstream's continuous integration.
When we cut a new zstd release, we will submit a patch to the kernel to update
the zstd version in the kernel.
The automated process makes it easy to keep the kernel version of zstd up to
date. The current zstd in the kernel shares the guts of the code, but has a lot
of API and minor changes to work in the kernel. This is because at the time
upstream zstd was not ready to be used in the kernel envrionment as-is. But,
since then upstream zstd has evolved to support being used in the kernel as-is.
Why are we updating in one big patch?
-------------------------------------
The 3rd patch in the series is very large. This is because it is restructuring
the code, so it both deletes the existing zstd, and re-adds the new structure.
Future updates will be directly proportional to the changes in upstream zstd
since the last import. They will admittidly be large, as zstd is an actively
developed project, and has hundreds of commits between every release. However,
there is no other great alternative.
One option ruled out is to replay every upstream zstd commit. This is not feasible
for several reasons:
- There are over 3500 upstream commits since the zstd version in the kernel.
- The automation to automatically generate the kernel update was only added recently,
so older commits cannot easily be imported.
- Not every upstream zstd commit builds.
- Only zstd releases are "supported", and individual commits may have bugs that were
fixed before a release.
Another option to reduce the patch size would be to first reorganize to the new
file structure, and then apply the patch. However, the current kernel zstd is formatted
with clang-format to be more "kernel-like". But, the new method imports zstd as-is,
without additional formatting, to allow for closer correlation with upstream, and
easier debugging. So the patch wouldn't be any smaller.
It also doesn't make sense to import upstream zstd commit by commit going
forward. Upstream zstd doesn't support production use cases running of the
development branch. We have a lot of post-commit fuzzing that catches many bugs,
so indiviudal commits may be buggy, but fixed before a release. So going forward,
I intend to import every (important) zstd release into the Kernel.
So, while it isn't ideal, updating in one big patch is the only patch I see forward.
Who is responsible for this code?
---------------------------------
I am. This patchset adds me as the maintainer for zstd. Previously, there was no tree
for zstd patches. Because of that, there were several patches that either got ignored,
or took a long time to merge, since it wasn't clear which tree should pick them up.
I'm officially stepping up as maintainer, and setting up my tree as the path through
which zstd patches get merged. I'll make sure that patches to the kernel zstd get
ported upstream, so they aren't erased when the next version update happens.
How is this code tested?
------------------------
I tested every caller of zstd on x86_64 (BtrFS, ZRAM, SquashFS, F2FS, Kernel,
InitRAMFS). I also tested Kernel & InitRAMFS on i386 and aarch64. I checked both
performance and correctness.
Also, thanks to many people in the community who have tested these patches locally.
If you have tested the patches, please reply with a Tested-By so I can collect them
for the PR I will send to Linus.
Lastly, this code will bake in linux-next before being merged into v5.16.
Why update to zstd-1.4.10 when zstd-1.5.0 has been released?
------------------------------------------------------------
This patchset has been outstanding since 2020, and zstd-1.4.10 was the latest
release when it was created. Since the update patch is automatically generated
from upstream, I could generate it from zstd-1.5.0. However, there were some
large stack usage regressions in zstd-1.5.0, and are only fixed in the latest
development branch. And the latest development branch contains some new code that
needs to bake in the fuzzer before I would feel comfortable releasing to the
kernel.
Once this patchset has been merged, and we've released zstd-1.5.1, we can update
the kernel to zstd-1.5.1, and exercise the update process.
You may notice that zstd-1.4.10 doesn't exist upstream. This release is an
artifical release based off of zstd-1.4.9, with some fixes for the kernel
backported from the development branch. I will tag the zstd-1.4.10 release after
this patchset is merged, so the Linux Kernel is running a known version of zstd
that can be debugged upstream.
Why was a wrapper API added?
----------------------------
The first versions of this patchset migrated the kernel to the upstream zstd
API. It first added a shim API that supported the new upstream API with the old
code, then updated callers to use the new shim API, then transitioned to the
new code and deleted the shim API. However, Cristoph Hellwig suggested that we
transition to a kernel style API, and hide zstd's upstream API behind that.
This is because zstd's upstream API is supports many other use cases, and does
not follow the kernel style guide, while the kernel API is focused on the
kernel's use cases, and follows the kernel style guide.
Where is the previous discussion?
---------------------------------
Links for the discussions of the previous versions of the patch set.
The largest changes in the design of the patchset are driven by the discussions
in V11, V5, and V1. Sorry for the mix of links, I couldn't find most of the the

Pull zstd update from Nick Terrell:
"Update to zstd-1.4.10.
Add myself as the maintainer of zstd and update the zstd version in
the kernel, which is now 4 years out of date, to a much more recent

- Update MAINTAINERS information (mailing list, web page, etc).
- Add a semantic patch from Wen Yang to check for do_div calls that may
cause truncation, motivated by commit b0ab99e773 ("sched: Fix
possible divide by zero in avg_atom() calculation")

coccinelle: semantic patch to check for inappropriate do_div() calls
Some side notes on this. Atm we do want to use gitlab for bug tracking and
merge requests. But due to the nature of the current linux kernel
development, we can only do so for nouveau internal changes.
Everything else still needs to be sent as emails and this is also includes
changes to UAPI etc.
Anyway, if somebody wants to submit patches via gitlab, they are free to
do so and this should just make this more official and documented.
People listed as maintainers are such that have push access to drm-misc
(where changes are pushed to after landing in gitlab) and are known
nouveau developers.
We did this already for some trivial changes and critical bug fixes
already, we just weren't thinking about updating the MAINTAINERS file.

TL;DR: While a tool like liblockdep is useful, it probably doesn't
belong within the kernel tree.
liblockdep attempts to reuse kernel code both directly (by directly
building the kernel's lockdep code) as well as indirectly (by using
sanitized headers). This makes liblockdep an integral part of the
kernel.
It also makes liblockdep quite unique: while other userspace code might
use sanitized headers, it generally doesn't attempt to use kernel code
directly which means that changes on the kernel side of things don't
affect (and break) it directly.
All our workflows and tooling around liblockdep don't support this
uniqueness. Changes that go into the kernel code aren't validated to not
break in-tree userspace code.
liblockdep ended up being very fragile, breaking over and over, to the
point that living in the same tree as the lockdep code lost most of it's
value.
liblockdep should continue living in an external tree, syncing with
the kernel often, in a controllable way.

The Qualcomm modem and TrustZone based remoteproc drivers gains support
for the modem in SC7280 and MSM8996 gains support for a missing

Throughout the Qualcomm drivers, the support for informing the always-on
power coprocessor about the state of each remoteproc is reworked to
avoid complications related to our use of genpd and the system suspend
state.
Lastly a number of small fixes are found throughout the drivers and

Commit 7a6ff4c4cb ("misc: hisi_hikey_usb: Driver to support onboard
USB gpio hub on Hikey960") refers to the non-existing file
Documentation/devicetree/bindings/misc/hisilicon-hikey-usb.yaml, but
this commit's patch series does not add any related devicetree binding
in misc.
So, just drop this file reference in HIKEY960 ONBOARD USB GPIO HUB DRIVER.

Patch series "Rectify file references for dt-bindings in MAINTAINERS", v5.
A patch series that cleans up some file references for dt-bindings in
MAINTAINERS.
This patch (of 4):
Commit 836863a08c ("MAINTAINERS: Add information for Toshiba Visconti
ARM SoCs") refers to the non-existing file toshiba,tmpv7700-pinctrl.yaml
in ./Documentation/devicetree/bindings/pinctrl/. Commit 1825c1fe00
("pinctrl: Add DT bindings for Toshiba Visconti TMPV7700 SoC")
originating from the same patch series however adds the file
toshiba,visconti-pinctrl.yaml in that directory instead.
So, refer to toshiba,visconti-pinctrl.yaml in the ARM/TOSHIBA VISCONTI
ARCHITECTURE section instead.

I'd like more continuity of review for the exec and binfmt (and ELF)
stuff. Eric and I have been the most active lately, so list us as
reviewers.
