Mauro Carvalho Chehab 3b54fc5077 ABI: stable/sysfs-module: better document modules
Instead of placing almost everything there as a text, use
the proper What: for each component of the ABI.

This allows it to be better documented and parsed by
get_abi.pl.

While here, use wildcards for MODULENAME.

Mauro Carvalho Chehab 483f7d699f ABI: evm: place a second what at the next line
Originally, get_abi.pl was using spaces to separate What: parameters,
but there are several references that declare things like:

	/sys/class/powercap/.../<power zone>/enabled

So, the logic was changes in order to properly address it.
That broke the second What added by
Changeset 18e49b3046 ("ABI: security: fix location for evm and ima_policy").

As the only file that defines multiple What: at the same line is
this file, let's move the second What: to a separate line.

Mauro Carvalho Chehab 26d98b9cc0 ABI: sysfs-platform-dell-privacy-wmi: correct ABI entries
As described at Documentation/ABI/README doesn't contain an
Attribute: field.

The way sysfs ABI is supposed to work is that each different
attribute would have a separate file. So, the right way to
map this would be like:

	/sys/.../dell_privacy_supported_type/mic_mute
	/sys/.../dell_privacy_supported_type/camera_shutter

	/sys/.../dell_privacy_current_state/mic_mute
	/sys/.../dell_privacy_current_state/camera_shutter

However, it seems to late to fix that, as this was merged already on
Kernel 5.13, and a change right now would be a regression.

So, instead, let's at least fix the entry to match the expected
format.

While here, fix the format of the contact, which is not a valid
e-mail URL.

This should also fix the current warnings produced when building the
docs:

	Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi:35: WARNING: Unexpected indentation.
	Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi:2: WARNING: Unexpected indentation.

Mauro Carvalho Chehab 24d732a908 ABI: sysfs-bus-pci: use wildcards on What definitions
An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl

While humans may be able to understand that something like:

could actually mean:

This is something that computers can't easily identify. As

Linus Torvalds 6abaa83c73 f2fs-for-5.15-rc1
In this cycle, we've addressed some performance issues such as lock contention,
 misbehaving compress_cache, allowing extent_cache for compressed files, and new
 sysfs to adjust ra_size for fadvise. In order to diagnose the performance issues
 quickly, we also added an iostat which shows the IO latencies periodically. On
 the stability side, we've found two memory leakage cases in the error path in
 compression flow. And, we've also fixed various corner cases in fiemap, quota,
 checkpoint=disable, zstd, and so on.
 
 Enhancement:
  - avoid long checkpoint latency by releasing nat_tree_lock
  - collect and show iostats periodically
  - support extent_cache for compressed files
  - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
  - report f2fs GC status via sysfs
  - add discard_unit=%s in mount option to handle zoned device
 
 Bug fix:
  - fix two memory leakages when an error happens in the compressed IO flow
  - fix commpress_cache to get the right LBA
  - fix fiemap to deal with compressed case correctly
  - fix wrong EIO returns due to SBI_NEED_FSCK
  - fix missing writes when enabling checkpoint back
  - fix quota deadlock
  - fix zstd level mount option
 
 In addition to the above major updates, we've cleaned up several code paths such
 as dio, unnecessary operations, debugfs/f2fs/status, sanity check, and typos.

Huang Ying 20b51af15e mm/migrate: add sysfs interface to enable reclaim migration
Some method is obviously needed to enable reclaim-based migration.

Just like traditional autonuma, there will be some workloads that will
benefit like workloads with more "static" configurations where hot pages
stay hot and cold pages stay cold.  If pages come and go from the hot and
cold sets, the benefits of this approach will be more limited.

The benefits are truly workload-based and *not* hardware-based.  We do not
believe that there is a viable threshold where certain hardware
configurations should have this mechanism enabled while others do not.

To be conservative, earlier work defaulted to disable reclaim- based
migration and did not include a mechanism to enable it.  This proposes add
a new sysfs file

  /sys/kernel/mm/numa/demotion_enabled

as a method to enable it.

We are open to any alternative that allows end users to enable this
mechanism or disable it if workload harm is detected (just like
traditional autonuma).

Once this is enabled page demotion may move data to a NUMA node that does
not fall into the cpuset of the allocating process.  This could be
construed to violate the guarantees of cpusets.  However, since this is an
opt-in mechanism, the assumption is that anyone enabling it is content to
relax the guarantees.

Linus Torvalds a9c9a6f741 SCSI misc on 20210902
This series consists of the usual driver updates (ufs, qla2xxx,
 target, smartpqi, lpfc, mpt3sas).  The core change causing the most
 churn was replacing the command request field request with a macro,
 allowing us to offset map to it and remove the redundant field; the
 same was also done for the tag field.  The most impactful change is
 the final removal of scsi_ioctl, which has been deprecated for over a
 decade.

Linus Torvalds 57c78a234e arm64 updates for 5.15:
- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
   scheduler changes merged via the tip tree).
 
 - More entry.S clean-ups and conversion to C.
 
 - MTE updates: allow a preferred tag checking mode to be set per CPU

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core
   - DP aux bus support

Greg Kroah-Hartman 4cd67adc44 This tag contains habanalabs driver changes for v5.15:
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

Linus Torvalds ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,
  rather than do the mindless fixup to code that isn't actually
  reachable                                               - Linus ]

The most recent dumps shall be accessible via debugfs, under

Robin Murphy 26225bea1d iommu: Expose DMA domain strictness via sysfs
The sysfs interface for default domain types exists primarily so users
can choose the performance/security tradeoff relevant to their own
workload. As such, the choice between the policies for DMA domains fits
perfectly as an additional point on that scale - downgrading a
particular device from a strict default to non-strict may be enough to
let it reach the desired level of performance, while still retaining
more peace of mind than with a wide-open identity domain. Now that we've
abstracted non-strict mode as a distinct type of DMA domain, allow it to
be chosen through the user interface as well.

THOBY Simon 4f2946aa0c IMA: introduce a new policy option func=SETXATTR_CHECK
While users can restrict the accepted hash algorithms for the
security.ima xattr file signature when appraising said file, users
cannot restrict the algorithms that can be set on that attribute:
any algorithm built in the kernel is accepted on a write.

Define a new value for the ima policy option 'func' that restricts
globally the hash algorithms accepted when writing the security.ima
xattr.

When a policy contains a rule of the form
	appraise func=SETXATTR_CHECK appraise_algos=sha256,sha384,sha512
only values corresponding to one of these three digest algorithms
will be accepted for writing the security.ima xattr.  Attempting to
write the attribute using another algorithm (or "free-form" data)
will be denied with an audit log message.  In the absence of such a
policy rule, the default is still to only accept hash algorithms
built in the kernel (with all the limitations that entails).

THOBY Simon 583a80ae86 IMA: add a policy option to restrict xattr hash algorithms on appraisal
The kernel has the ability to restrict the set of hash algorithms it
accepts for the security.ima xattr when it appraises files.

Define a new IMA policy rule option "appraise_algos=", using the
mentioned mechanism to expose a user-toggable policy knob to opt-in
to that restriction and select the desired set of algorithms that
must be accepted.

When a policy rule uses the 'appraise_algos' option, appraisal of a
file referenced by that rule will now fail if the digest algorithm
employed to hash the file was not one of those explicitly listed in
the option.  In its absence, any hash algorithm compiled in the
kernel will be accepted.

For example, on a system where SELinux is properly deployed, the rule
	appraise func=BPRM_CHECK obj_type=iptables_exec_t \
		appraise_algos=sha256,sha384
will block the execution of iptables if the xattr security.ima of its
executables were not hashed with either sha256 or sha384.

Hans de Goede b25d5a1cd1 ACPI: platform-profile: call sysfs_notify() from platform_profile_store()
Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.

This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.

Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.

Also update the documentation to document that POLLPRI polling can be
used to watch for changes.

Greg Kroah-Hartman f805ef1ce5 First set of new IIO and counter device support, cleanups and features for 5.15
Usual mix of cleanups and new device support.
 
 Counter
 ======
 
 Cleanups and refactoring:
 * treewide
   - Ensure attempts to set invalid modes result in -EINVAL return.
   - Rename counter_count_function to counter_function as the middle count
     is redundant.
   - Standardize error returns when limits are exceeded.
 * 104-quad:
   - Document the lock.
   - Return an error if attempt to set the ceiling value in a mode that
     doesn't support it.
 * intel-qep
   - Drop unused bitops.h include
 
 IIO
 ===
 
 New device support
 * bma255
   - Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
     interrupt pin and not INT1. Patch set includes enabling use of INT2.
 * ingenic_adc
   - Add support for JZ4760 and similar and update bindings
   - Add support for JZ4760B and update bindings
 * rockchip_saradc
   - Add support for rk3568 ADC (separate channel array as more channels)
 * sgp40 gas sensor used to measure air quality
   - New driver including binding and ABI documentation.
 
 Bindings
 --------
 
 * Add missing bindings for many DACs where the binding was effectively
   implicit due to fallback probe methods in I2C and SPI.
   adi,ad5064
   adi,ad5360
   adi,ad5380
   adi,ad5421
   adi,ad5449
   adi,ad5504
   adi,ad5624r
   adi,ad5686 / adi,ad5696
   adi,ad5761
   adi,ad5764
   adi,ad5791
   adi,ad8801
   capella,cm3323 (also add explicit of_device_id table)
   microchip,mcp4922
 * bosch,bma255
   - Interrupt type in example was opposite of what the device expects.
     It's possible that a particular board had an inverter, but we
     definitely don't want the example to suggest this would be normal.
   - Add interrupt-names to allow for cases where only INT2 is connected.
   - Sort compatibles
   - Merge in very similar bosch,bma180 binding.
 
 New feature
 -----------
 
 * Devices only allowed to provide either extended_name or a label for given
   channel. If extend_name is used (generally discouraged but can't be
   removed as it would be a userspaece ABI change), then the label sysfs
   attribute will provide the extended_name. This allows some userspace
   parser simplications and hardening.
 * hid-sensors-pres
   - Add a timestamp channel (either from hardware, or locally filled).
 * vcnl3020
   - Add periodic sensor mode used to provide IIO events.
 
 Cleanups / minor fixes
 ----------------------
 
 * core/buffers
   - Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
   - Move a sanity check earlier to simplify error path.
 * Quite a few cases of refactors to use devm_* for all of probe and drop
   remove
   - adjd_s311
   - adxl345
   - bma220
   - da280
   - dmard10
   - ds311
   - max5481
   - max5821
   - rfd77402
   - tcs3414
   - tmp006
 * ad5624r
   - Fix incorrect handling of a regulator that was preventing use of
     internal regulators.
 * adjd_s311
   - Allocate a buffer as part of iio_priv() structure as maximum size
     is small enough, no significant advantage in making it flexible sized.
 * bma220
   - Make handling of suspend and resume closer to the probe() wrt to the
     rather odd interface, that suspend mode is entered by reading a register.
 * ep93xx
   - Prepare clock before using (part of conversion to CCF)
 * fsl-imx25-gcq
   - Use local device pointer.
   - Adjust handling of platform_get_irq() to not check for 0 as an error.
     The function is documented as never returning it.
 * hid-sensors
   - Use devm_kmemdup() consistently across all drivers to simplify channel
     structure allocation management.
 * meson-saradc
   - Drop BL30 integration on G12A and newer SoCs as not used.
   - Whitespace fixes.
 * mpu6050
   - Add per device type startup times. This avoids an issue with having
     to dsicard initial data from gyroscopes when they were still stabilizing.
 * rfd77402
   - Change from passing private data, to passing i2c_client where only
     that is needed, reducing back and forth in pm functions.
 * si1145
   - Drop pointless continue
 * st-sensors
   - Cleanup of includes to remove unused and add missing headers that are used.
   - Use some devm functions to simplify probe() and remove() - gets us part way
     towards a fully device managed driver.
 * sx9310
   - Switch from of to generic properties to enable ACPI bindings.
 * vcnl3020
   - Add DMA safe buffer for bulk transfers.
   - Drop use of iio_claim_direct() in a driver that has no mode changes.
     A local lock is more appropriate.

Merge tag 'iio-for-5.15a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new IIO and counter device support, cleanups and features for 5.15

Usual mix of cleanups and new device support.

Counter
======

Cleanups and refactoring:
* treewide
  - Ensure attempts to set invalid modes result in -EINVAL return.
  - Rename counter_count_function to counter_function as the middle count
    is redundant.
  - Standardize error returns when limits are exceeded.
* 104-quad:
  - Document the lock.
  - Return an error if attempt to set the ceiling value in a mode that
    doesn't support it.
* intel-qep
  - Drop unused bitops.h include

IIO
===

New device support
* bma255
  - Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
    interrupt pin and not INT1. Patch set includes enabling use of INT2.
* ingenic_adc
  - Add support for JZ4760 and similar and update bindings
  - Add support for JZ4760B and update bindings
* rockchip_saradc
  - Add support for rk3568 ADC (separate channel array as more channels)
* sgp40 gas sensor used to measure air quality
  - New driver including binding and ABI documentation.

Bindings
--------

* Add missing bindings for many DACs where the binding was effectively
  implicit due to fallback probe methods in I2C and SPI.
  adi,ad5064
  adi,ad5360
  adi,ad5380
  adi,ad5421
  adi,ad5449
  adi,ad5504
  adi,ad5624r
  adi,ad5686 / adi,ad5696
  adi,ad5761
  adi,ad5764
  adi,ad5791
  adi,ad8801
  capella,cm3323 (also add explicit of_device_id table)
  microchip,mcp4922
* bosch,bma255
  - Interrupt type in example was opposite of what the device expects.
    It's possible that a particular board had an inverter, but we
    definitely don't want the example to suggest this would be normal.
  - Add interrupt-names to allow for cases where only INT2 is connected.
  - Sort compatibles
  - Merge in very similar bosch,bma180 binding.

New feature
-----------

* Devices only allowed to provide either extended_name or a label for given
  channel. If extend_name is used (generally discouraged but can't be
  removed as it would be a userspaece ABI change), then the label sysfs
  attribute will provide the extended_name. This allows some userspace
  parser simplications and hardening.
* hid-sensors-pres
  - Add a timestamp channel (either from hardware, or locally filled).
* vcnl3020
  - Add periodic sensor mode used to provide IIO events.

Cleanups / minor fixes
----------------------

* core/buffers
  - Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
  - Move a sanity check earlier to simplify error path.
* Quite a few cases of refactors to use devm_* for all of probe and drop
  remove
  - adjd_s311
  - adxl345
  - bma220
  - da280
  - dmard10
  - ds311
  - max5481
  - max5821
  - rfd77402
  - tcs3414
  - tmp006
* ad5624r
  - Fix incorrect handling of a regulator that was preventing use of
    internal regulators.
* adjd_s311
  - Allocate a buffer as part of iio_priv() structure as maximum size
    is small enough, no significant advantage in making it flexible sized.
* bma220
  - Make handling of suspend and resume closer to the probe() wrt to the
    rather odd interface, that suspend mode is entered by reading a register.
* ep93xx
  - Prepare clock before using (part of conversion to CCF)
* fsl-imx25-gcq
  - Use local device pointer.
  - Adjust handling of platform_get_irq() to not check for 0 as an error.
    The function is documented as never returning it.
* hid-sensors
  - Use devm_kmemdup() consistently across all drivers to simplify channel
    structure allocation management.
* meson-saradc
  - Drop BL30 integration on G12A and newer SoCs as not used.
  - Whitespace fixes.
* mpu6050
  - Add per device type startup times. This avoids an issue with having
    to dsicard initial data from gyroscopes when they were still stabilizing.
* rfd77402
  - Change from passing private data, to passing i2c_client where only
    that is needed, reducing back and forth in pm functions.
* si1145
  - Drop pointless continue
* st-sensors
  - Cleanup of includes to remove unused and add missing headers that are used.
  - Use some devm functions to simplify probe() and remove() - gets us part way
    towards a fully device managed driver.
* sx9310
  - Switch from of to generic properties to enable ACPI bindings.
* vcnl3020
  - Add DMA safe buffer for bulk transfers.
  - Drop use of iio_claim_direct() in a driver that has no mode changes.
    A local lock is more appropriate.

Andreas Klinger 1081b9d971 iio: chemical: Add driver support for sgp40
sgp40 is a gas sensor used for measuring the air quality.

This driver is reading the raw resistance value which can be passed to
an userspace algorithm for further calculation.

The raw value is also used to calculate an estimated absolute voc index
in the range from 0 to 500. For this purpose the raw_mean value of the
resistance for which the index value is 250 might be set up as a
calibration step. This can be done with in_resistance_calibbias.

Compensation of relative humidity and temperature is supported and can
be used by writing to output values of out_humidityrelative_raw and
out_temp_raw.

There is a predecesor sensor type (sgp30) already existing. This driver
module was not extended because the new sensor is quite different in its
i2c telegrams.

Sebastian Reichel 0f920277dc misc: gehc-achc: new driver
General Electric Healthcare's PPD has a secondary processor from
NXP's Kinetis K20 series. That device has two SPI chip selects:

The main interface's behaviour depends on the loaded firmware
and is currently unused.

The secondary interface can be used to update the firmware using
EzPort protocol. This is implemented by this driver using the
kernel's firmware API. The firmware is being flashed into
non-volatile flash memory, so it is enough to flash it once
and not on every boot. Flashing will wear the flash memory
(it has a life time of at least 10k programming cycles). At
the same time only occasional FW updates are expected (like e.g.
a BIOS update). Thus the firmware update is triggered via sysfs
instead of doing it in the driver's probe routine like many
other drivers.

Daejun Park 41d8a9333c scsi: ufs: ufshpb: Add HPB 2.0 support
Version 2.0 of HBP supports reads of varying sizes from 4KB to 1MB.

A read operation <= 32KB is supported as single HPB read. A read between
36KB and 1MB is supported by a combination of write buffer command and HPB
read command to deliver more PPN. The write buffer commands may not be
issued immediately due to busy tags. To use HPB read more aggressively, the
driver can requeue the write buffer command. The requeue threshold is
implemented as timeout and can be modified with requeue_timeout_ms entry in
sysfs.

Daejun Park f02bc9754a scsi: ufs: ufshpb: Introduce Host Performance Buffer feature
Implement Host Performance Buffer (HPB) initialization and add function
calls to UFS core driver.

NAND flash-based storage devices, including UFS, have mechanisms to
translate logical addresses of I/O requests to the corresponding physical
addresses of the flash storage.  In UFS, logical-to-physical-address (L2P)
map data, which is required to identify the physical address for the
requested I/Os, can only be partially stored in SRAM from NAND flash. Due
to this partial loading, accessing the flash address area, where the L2P
information for that address is not loaded in the SRAM, can result in
serious performance degradation.

The basic concept of HPB is to cache L2P mapping entries in host system
memory so that both physical block address (PBA) and logical block address
(LBA) can be delivered in HPB read command. The HPB read command allows to
read data faster than a regular read command in UFS since it provides the
physical address (HPB Entry) of the desired logical block in addition to
its logical address. The UFS device can access the physical block in NAND
directly without searching and uploading L2P mapping table. This improves
read performance because the NAND read operation for uploading L2P mapping
table is removed.

In HPB initialization, the host checks if the UFS device supports HPB
feature and retrieves related device capabilities. Then, HPB parameters are
configured in the device.

Total start-up time of popular applications was measured and the difference
observed between HPB being enabled and disabled. Popular applications are
12 game apps and 24 non-game apps. Each test cycle consists of running 36
applications in sequence. We repeated the cycle for observing performance
improvement by L2P mapping cache hit in HPB.

The following is the test environment:

 - kernel version: 4.4.0
 - RAM: 8GB
 - UFS 2.1 (64GB)

Results:

   +-------+----------+----------+-------+
   | cycle | baseline | with HPB | diff  |
   +-------+----------+----------+-------+
   | 1     | 272.4    | 264.9    | -7.5  |
   | 2     | 250.4    | 248.2    | -2.2  |
   | 3     | 226.2    | 215.6    | -10.6 |
   | 4     | 230.6    | 214.8    | -15.8 |
   | 5     | 232.0    | 218.1    | -13.9 |
   | 6     | 231.9    | 212.6    | -19.3 |
   +-------+----------+----------+-------+

We also measured HPB performance using iozone:

   $ iozone -r 4k -+n -i2 -ecI -t 16 -l 16 -u 16 -s $IO_RANGE/16 -F \
   mnt/tmp_1 mnt/tmp_2 mnt/tmp_3 mnt/tmp_4 mnt/tmp_5 mnt/tmp_6 mnt/tmp_7 \

Ruslan Bilovol 0356e6283c usb: gadget: f_uac1: add volume and mute support
This adds bi-directional (host->device, device->host)
volume/mute support to the f_uac1 driver by adding
Feature Units and interrupt endpoint.

Currently only master channel is supported.

Volume and mute are configurable through configfs,
by default volume has -100..0 dB range with 1 dB step.

Similar to existing flexible endpoints configuration,
Feature Unit won't be added to the topology if both
mute and volume are not enabled, also interrupt endpoint
isn't added to the device if no feature unit is present

Hridya Valsaraju c715def515 dma-buf: Delete the DMA-BUF attachment sysfs statistics
The DMA-BUF attachment statistics form a subset of the DMA-BUF
sysfs statistics that recently merged to the drm-misc tree. They are not
UABI yet since they have not merged to the upstream Linux kernel.

Since there has been a reported a performance regression due to the
overhead of sysfs directory creation/teardown during
dma_buf_attach()/dma_buf_detach(), this patch deletes the DMA-BUF
attachment statistics from sysfs.

Fixes: bdb8d06dfe ("dmabuf: Add the capability to expose DMA-BUF stats in sysfs")

1) "gc_reclaimed_segments" shows how many segments have been

Linus Torvalds 227c4d507c f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
 such as allowing compression for mmap files, replacing the immutable bit with
 internal bit to prohibits data writes explicitly, and adding a mount option,
 "compress_cache", to improve random reads. And, we added "readonly" feature to
 compact the partition w/ compression enabled, which will be useful for Android
 RO partitions.
 
 Enhancement:
  - support compression for mmap file
  - use an f2fs flag instead of IMMUTABLE bit for compression
  - support RO feature w/ extent_cache
  - fully support swapfile with file pinning
  - improve atgc tunability
  - add nocompress extensions to unselect files for compression
 
 Bug fix:
  - fix false alaram on iget failure during GC
  - fix race condition on global pointers when there are multiple f2fs instances
  - add MODULE_SOFTDEP for initramfs
 
 As usual, we've also cleaned up some places for better code readability.
 (e.g., sysfs/feature, debugging messages, slab cache name, and docs)

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've improved the compression support especially for
  Android such as allowing compression for mmap files, replacing the
  immutable bit with internal bit to prohibits data writes explicitly,
  and adding a mount option, "compress_cache", to improve random reads.
  And, we added "readonly" feature to compact the partition w/
  compression enabled, which will be useful for Android RO partitions.

  Enhancements:
   - support compression for mmap file
   - use an f2fs flag instead of IMMUTABLE bit for compression
   - support RO feature w/ extent_cache
   - fully support swapfile with file pinning
   - improve atgc tunability
   - add nocompress extensions to unselect files for compression

  Bug fixes:
   - fix false alaram on iget failure during GC
   - fix race condition on global pointers when there are multiple f2fs
     instances
   - add MODULE_SOFTDEP for initramfs

  As usual, we've also cleaned up some places for better code
  readability (e.g., sysfs/feature, debugging messages, slab cache
  name, and docs)"

Linus Torvalds a16d8644ba Staging / IIO driver patches for 5.14-rc1
Here is the big set of IIO and staging driver patches for 5.14-rc1.
 
 Loads of IIO driver updates and additions in here, the shortlog has the
 full details.
 
 For the staging side, we moved a few drivers out of staging, and deleted
 the kpc2000 drivers as the original developer asked us to because no one
 was working on them anymore.
 
 Also in here are loads of coding style cleanups due to different intern
 projects focusing on the staging tree to try to get experience doing
 kernel development.
 
 All of these have been in the linux-next tree for a while with no
 reported problems.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

   - Define a device model for an HDM decoder tree

   - Bridge CXL persistent memory capabilities to an NVDIMM bus /
     device-model

   - Switch to fine grained mapping of CXL MMIO registers to allow
     different drivers / system software to own individual register
     blocks

   - Enable media provisioning commands, and publish the label storage
     area size in sysfs

   - Miscellaneous cleanups and fixes"

Kan Liang 8053f2d752 perf/x86/intel/uncore: Add alias PMU name
A perf PMU may have two PMU names. For example, Intel Sapphire Rapids
server supports the discovery mechanism. Without the platform-specific
support, an uncore PMU is named by a type ID plus a box ID, e.g.,
uncore_type_0_0, because the real name of the uncore PMU cannot be
retrieved from the discovery table. With the platform-specific support
later, perf has the mapping information from a type ID to a specific
uncore unit. Just like the previous platforms, the uncore PMU is named
by the real PMU name, e.g., uncore_cha_0. The user scripts which work
well with the old numeric name may not work anymore.

Add a new attribute "alias" to indicate the old numeric name. The
following userspace perf tool patch will handle both names. The user
scripts should work properly with the updated perf tool.

Yangbo Lu 73f37068d5 ptp: support ptp physical/virtual clocks conversion
Support ptp physical/virtual clocks conversion via sysfs.
There will be a new attribute n_vclocks under ptp physical
clock sysfs.

- In default, the value is 0 meaning only ptp physical clock
  is in use.
- Setting the value can create corresponding number of ptp
  virtual clocks to use. But current physical clock is guaranteed
  to stay free running.
- Setting the value back to 0 can delete virtual clocks and back
  use physical clock again.

Another new attribute max_vclocks control the maximum number of
ptp vclocks.

Vaibhav Jain ed78f56e12 powerpc/papr_scm: Make 'perf_stats' invisible if perf-stats unavailable
In case performance stats for an nvdimm are not available, reading the
'perf_stats' sysfs file returns an -ENOENT error. A better approach is
to make the 'perf_stats' file entirely invisible to indicate that
performance stats for an nvdimm are unavailable.

So this patch updates 'papr_nd_attribute_group' to add a 'is_visible'
callback implemented as newly introduced 'papr_nd_attribute_visible()'
that returns an appropriate mode in case performance stats aren't
supported in a given nvdimm.

Also the initialization of 'papr_scm_priv.stat_buffer_len' is moved
from papr_scm_nvdimm_init() to papr_scm_probe() so that it value is
available when 'papr_nd_attribute_visible()' is called during nvdimm
initialization.

Even though 'perf_stats' attribute is available since v5.9, there are
no known user-space tools/scripts that are dependent on presence of its
sysfs file. Hence I dont expect any user-space breakage with this
patch.

Let's create /sys/fs/f2fs/<disk>/feature_list/ to meet sysfs rule.

Note that there are three feature list entries:
1) /sys/fs/f2fs/features
  : shows runtime features supported by in-kernel f2fs along with Kconfig.
    - ref. F2FS_FEATURE_RO_ATTR()

2) /sys/fs/f2fs/$s_id/features <deprecated>
  : shows on-disk features enabled by mkfs.f2fs, used for old kernels. This
    won't add new feature anymore, and thus, users should check entries in 3)
    instead of this 2).

3) /sys/fs/f2fs/$s_id/feature_list
  : shows on-disk features enabled by mkfs.f2fs per instance, which follows
    sysfs entry rule where each entry should expose single value.
    This list covers old feature list provided by 2) and beyond. Therefore,
    please add new on-disk feature in this list only.

Perry Yuan 8af9fa37b8 platform/x86: dell-privacy: Add support for Dell hardware privacy
add support for Dell privacy driver for the Dell units equipped
hardware privacy design, which protect users privacy of audio and
camera from hardware level. Once the audio or camera privacy mode
activated, any applications will not get any audio or video stream
when user pressed ctrl+F4 hotkey, audio privacy mode will be
enabled, micmute led will be also changed accordingly
The micmute led is fully controlled by hardware & EC(embedded controller)
and camera mute hotkey is Ctrl+F9. Currently design only emits
SW_CAMERA_LENS_COVER event while the camera lens shutter will be
changed by EC & HW(hardware) control

*The flow is like this:
1) User presses key. HW does stuff with this key (timeout timer is started)
2) WMI event is emitted from BIOS to kernel
3) WMI event is received by dell-privacy
4) KEY_MICMUTE emitted from dell-privacy
5) Userland picks up key and modifies kcontrol for SW mute
6) Codec kernel driver catches and calls ledtrig_audio_set
7) dell-privacy notifies EC, the timeout is cancelled and the HW mute
   is activated. If the EC is not notified then the HW mic mute will
   activate when the timeout triggers, just a bit later than with the
   active ack.

Matthias Kaehlcke b4e326165e USB: misc: Add onboard_usb_hub driver
The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.

Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.

Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

Note: the current series only supports hubs connected directly to
a root hub (through xhci-plat), support for other configurations
could be added if needed.

Hridya Valsaraju bdb8d06dfe dmabuf: Add the capability to expose DMA-BUF stats in sysfs
Overview
========
The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It
allows statistics to be enabled for each DMA-BUF in sysfs by enabling
the config CONFIG_DMABUF_SYSFS_STATS.

The following stats will be exposed by the interface:

/sys/kernel/dmabuf/buffers/<inode_number>/exporter_name
/sys/kernel/dmabuf/buffers/<inode_number>/size
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter

The inode_number is unique for each DMA-BUF and was added earlier [1]
in order to allow userspace to track DMA-BUF usage across different
processes.

Use Cases
=========
The interface provides a way to gather DMA-BUF per-buffer statistics
from production devices. These statistics will be used to derive DMA-BUF
per-exporter stats and per-device usage stats for Android Bug reports.
The corresponding userspace changes can be found at [2].
Telemetry tools will also capture this information(along with other
memory metrics) periodically as well as on important events like a
foreground app kill (which might have been triggered by Low Memory
Killer). It will also contribute to provide a snapshot of the system
memory usage on other events such as OOM kills and Application Not
Responding events.

Background
==========
Currently, there are two existing interfaces that provide information
about DMA-BUFs.
1) /sys/kernel/debug/dma_buf/bufinfo
debugfs is however unsuitable to be mounted in production systems and
cannot be considered as an alternative to the sysfs interface being
proposed.
2) proc/<pid>/fdinfo/<fd>
The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds.
However, the existing procfs interfaces can only provide information
about the buffers for which processes hold fds or have the buffers
mmapped into their address space. Since the procfs interfaces alone
cannot provide a full picture of all DMA-BUFs in the system, there is
the need for an alternate interface to provide this information on
production systems.

The patch contains the following major improvements over v1:
1) Each attachment is represented by its own directory to allow creating
a symlink to the importing device and to also provide room for future
expansion.
2) The number of distinct mappings of each attachment is exposed in a
separate file.
3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers
inorder to make the interface expandable in future.

All of the improvements above are based on suggestions/feedback from
Daniel Vetter and Christian König.

A shell script that can be run on a classic Linux environment to read
out the DMA-BUF statistics can be found at [3](suggested by John
Stultz).

Dan Williams 40ba17afdf cxl/acpi: Introduce cxl_decoder objects
A cxl_decoder is a child of a cxl_port. It represents a hardware decoder
configuration of an upstream port to one or more of its downstream
ports. The decoder is either represented in CXL standard HDM decoder
registers (see CXL 2.0 section 8.2.5.12 CXL HDM Decoder Capability
Structure), or it is a static decode configuration communicated by
platform firmware (see the CXL Early Discovery Table: Fixed Memory
Window Structure).

The firmware described and hardware described decoders differ slightly
leading to 2 different sub-types of decoders, cxl_decoder_root and
cxl_decoder_switch. At the root level the decode capabilities restrict
what can be mapped beneath them. Mid-level switch decoders are
configured for either acclerator (type-2) or memory-expander (type-3)
operation, but they are otherwise agnostic to the type of memory
(volatile vs persistent) being mapped.

Here is an example topology from a single-ported host-bridge environment
without CFMWS decodes enumerated.

Dan Williams 7d4b5ca2e2 cxl/acpi: Add downstream port data to cxl_port instances
In preparation for infrastructure that enumerates and configures the CXL
decode mechanism of an upstream port to its downstream ports, add a
representation of a CXL downstream port.

On ACPI systems the top-most logical downstream ports in the hierarchy
are the host bridges (ACPI0016 devices) that decode the memory windows
described by the CXL Early Discovery Table Fixed Memory Window
Structures (CEDT.CFMWS).

Dan Williams 4812be97c0 cxl/acpi: Introduce the root of a cxl_port topology
While CXL builds upon the PCI software model for enumeration and
endpoint control, a static platform component is required to bootstrap
the CXL memory layout. Similar to how ACPI identifies root-level PCI
memory resources, ACPI data enumerates the address space and interleave
configuration for CXL Memory.

In addition to identifying host bridges, ACPI is responsible for
enumerating the CXL memory space that can be addressed by downstream
decoders. This is similar to the requirement for ACPI to publish
resources via the _CRS method for PCI host bridges. Specifically, ACPI
publishes a table, CXL Early Discovery Table (CEDT), which includes a
list of CXL Memory resources, CXL Fixed Memory Window Structures
(CFMWS).

For now, introduce the core infrastructure for a cxl_port hierarchy
starting with a root level anchor represented by the ACPI0017 device.

Follow on changes model support for the configurable decode capabilities
of cxl_port instances, i.e. CXL switch support.

Ruslan Bilovol e89bb42883 usb: gadget: u_audio: add real feedback implementation
This adds interface between userspace and feedback endpoint to report real
feedback frequency to the Host.

Current implementation adds new userspace interface ALSA mixer control
"Capture Pitch 1000000" (similar to aloop driver's "PCM Rate Shift 100000"
mixer control)

Value in PPM is chosen to have correction value agnostic of the actual HW
rate, which the application is not necessarily dealing with, while still
retaining a good enough precision to allow smooth clock correction on the
playback side, if necessary.

Similar to sound/usb/endpoint.c, a slow down is allowed up to 25%. This
has no impact on the required bandwidth. Speedup correction has an impact
on the bandwidth reserved for the isochronous endpoint. The default
allowed speedup is 500ppm. This seems to be more than enough but, if
necessary, this is configurable through a module parameter. The reserved
bandwidth is rounded up to the next packet size.

Usage of this new control is easy to implement in existing userspace tools
like alsaloop from alsa-utils.

new NVM operation (AUHENTICATE_ONLY) that just triggers the authentication
procedure over whatever was written to the NVM storage.

This is not supported with Thunderbolt 1-3 devices, though.
