ABI: sysfs-class-devfreq-event: use the right wildcards on What
On most ABI files, the wildcards are used as <x>, instead of (x). Replace it to make it using a more standard wildcard. That helps get_abi.pl to convert it into a regex.

ABI: sysfs-class-cxl: place "not in a guest" at description
The What: field should have just the location of the ABI. Anything else should be inside the description. This fixes its parsing by get_abi.pl script.

ABI: sysfs-bus-rapidio: use wildcards on What definitions
While humans may be able to understand that something like: /sys/bus/rapidio/devices/nn:d:iiii could actually mean: /sys/bus/rapidio/devices/00:e:0000 This is something that computers can't easily identify. As get_abi.pl needs to convert it into a regex, change What: lines to: /sys/bus/rapidio/devices/<nn>:<d>:<iiii> Which is the commonly-used pattern on ABI files for wildcards.

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.

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.

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. Signed-off-by: James E.J.

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. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE7TEboABC71LctBLFZR1NuKta54AFAmEvnt8ACgkQZR1NuKta 54B6GwgAgDZE/watviT5VzS/Cb5wXitOjLfq9eEOVqwD7+sT0c6PDSpIMiFnz4BV yCPttVAWJPgcQFde/6WXHz8kAsG1dMDQ6ClXHWwNyhxdjVuRAeoHjChlkoW3E0SW ZiSoWcQy6bCPmy0mfy6reZsJzO1IOokW0QpYVbQKbxaxS9TdVKhBIMWkALUPqQCz JfA2LEn4ZMbQIGdcm7gb5NI2xlBok94IKv3D5i9Isy3IyT1+yIYoncHZHDwBK6oV uhVvQK4it8i+wfEbxE1CHavPmXQXlvziIZNQ0TqlAOzncN4tc6a3mSdnJKcpinmS Gy93ceWgXxJDZbpTIXHB18lMg4z5yg== =I/ND -----END PGP SIGNATURE----- Merge tag 'misc-habanalabs-next-2021-09-01' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: 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.

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.

habanalabs: expose state dump
To improve the user's ability to debug the case where a workload that is part of executing training/inference of a topology is getting stuck, we need to add a 'core dump' each time a CS times-out. The 'core dump' shall contain all relevant Sync Manager information and corresponding fence values. The most recent dumps shall be accessible via debugfs, under 'state_dump' node. Reading from the node will provide the oldest dump available. Writing an integer value X will discard X dumps, starting with the oldest one, i.e. subsequent read will now return newer dumps.

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.

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).

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.

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. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.

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,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.

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,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

- adxl345

- 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.

platform/x86: Update Mario Limonciello's email address in the docs
Various pdx86 docs under Documentation/ABI/testing still use Mario's old, now defunct, <mario.limonciello@dell.com> address. Update the docs to point to either the new Dell.Client.Kernel@dell.com email alias for Dell specific drivers, or to Mario's new @outlook.com address for other drivers.

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.

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.

ACPI: DPTF: Add new PCH FIVR methods
Some additional information is required for updating PCH FIVR values upon WiFi channel changes. New attributes added to the existing sysfs: fivr_switching_freq_mhz : Get the FIVR switching control frequency. Uses ACPI method GFCS. fivr_switching_fault_status: Read the FIVR switching frequency control fault status. Uses ACPI method GFFS. ssc_clock_info : Presents SSC (spread spectrum clock) information for EMI (Electro magnetic interference) control. Use ACPI method GEMI (refer to the description of GEMI method below). GFFS This ACPI method is used to read the FIVR switching frequency control fault status. Bits Description [0:0] Fault status when set to 1 [31:1] Reserved GFCS This ACPI method is used to read the FIVR switching control frequency. Bits Description [11:0] Actual Frequency = value * XTAL_FREQ / 128 [31:12] Reserved GEMI This ACPI method is used to read the programmed register value for EMI (Electro magnetic interference) control. Bits Description [7:0] Sets clock spectrum spread percentage: 0x00=0.2% , 0x3F=10% 1 LSB = 0.1% increase in spread (for settings 0x01 thru 0x1C) 1 LSB = 0.2% increase in spread (for settings 0x1E thru 0x3F) [8] When set to 1, enables spread spectrum clock [9] 0: Triangle mode. FFC frequency walks around the Fcenter in a linear fashion 1: Random walk mode. FFC frequency changes randomly within the SSC (Spread spectrum clock) range [10] 0: No white noise. 1: Add white noise to spread waveform [11] When 1, future writes are ignored.
