power: supply: document current direction
Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit of a mess. There are basically 3 different ways battery fuel gauges report the current: 1. uses negative values for discharging and positive values for charging 2. uses positive values for discharging and negative values for discharging (opposit of 1) 3. only uses positive values As a result userspace currently cannot use the sign at all in a generic way. Let's solve the issue by documenting a canonical way for reporting the data and ensure new drivers follow this way. Then existing drivers can be fixed on a case-by-case basis. The 'negative value = battery discharging' has been choosen, since there are only very few drivers doing it the other way around. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com> |

w1: w1_therm: Add support for GXCAS GX20MH01 device.
GX20MH01 device shares family number 0x28 with DS18B20. The device is generally compatible with DS18B20. Added are the lowest 2^-5, 2^-6 temperature bits in Config register; R2 bit in Config register enabling 13 and 14 bit resolutions. It is powered up in 14 bit mode.

w1: w1_therm: Add sysfs entries to control conversion time and driver features
The conversion time of common DS18B20 clones deviates from
datasheet specs. Allow adjustment and automatic measure of the
conversion time.
Add 'conv_time' sysfs attribute:
*read*: Current conversion time in milliseconds.
*write*:
'0': Set default conversion time.
'1': Measure and set the conversion time. Make a
single temperature conversion, poll and measure
an actual value. Measured value is increased
by 20% for temperature drift. A new conversion
time is returned by reading the same attribute.
other positive value:
Set the conversion time in milliseconds.
The setting is active until a resolution change. Then it is reset to
default conversion time for a new resolution.
Add 'features' sysfs attribute to control optional driver settings
per device. Bit masks to read/write (logical OR):
1: Enable check for conversion success. If byte 6 of
scratchpad memory is 0xC after conversion, and
temperature reads 85.00 (powerup value) or 127.94
(insufficient power) - return a conversion error.
2: Enable poll for conversion completion. Generate read cycles
after the conversion start and wait for 1's. In parasite
power mode this feature is not available.
There are some clones of DS18B20 with fixed 12 bit resolution. Make the
driver verify the resolution by reading back the device after resolution
change.

mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC
This patch implements the basic functions of the BMC chip for some Intel FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the Intel MAX 10 CPLD. This BMC chip is connected to the FPGA by a SPI bus. To provide direct register access from the FPGA, the "SPI slave to Avalon Master Bridge" (spi-avmm) IP is integrated in the chip. It converts encoded streams of bytes from the host to the internal register read/write on the Avalon bus. So This driver uses the regmap-spi-avmm for register accessing.

soundwire: sysfs: add slave status and device number before probe
The MIPI DisCo device properties that are read by the driver from platform firmware, or hard-coded in the driver, should only be provided as sysfs entries when a driver probes successfully. However the device status and device number is updated even when there is no driver present, and hence can be updated when a Slave device is detected on the bus without being described in platform firmware and without any driver registered/probed. As suggested by GregKH, the attribute group for Slave status and device number is is added by default upon device registration. Credits to Vinod Koul for the status_show() function, shared in a separate patch and used as is here. The status table was modified to remove an unnecessary enum and status_show() is handled in a different group attribute than what was suggested by Vinod.

habanalabs: replace armcp with the generic cpucp
ArmCP mandates that the device CPU is always an ARM processor, which might be wrong in the future. Most of this change is an internal renaming of variables, functions and defines but there are two entries in sysfs which have armcp in their names. Add identical cpucp entries but don't remove yet the armcp entries. Those will be deprecated next year. Add the documentation about it in sysfs documentation.

ACPI: DPTF: Add PCH FIVR participant driver
This driver adds support for Dynamic Platform and Thermal Framework (DPTF) PCH (Platform Controller Hub) FIVR (Fully Integrated Voltage Regulator) participant support. This participant is responsible for exposing platform telemetry and control for: freq_mhz_high_clock freq_mhz_low_clock These attributes are used to get and set PCH FIVR switching frequency for thermal and radio frequency interference mitigation.

iio: temperature: mlx90632: Interface to change object ambient temperature
Since object temperature might be different than the sensor temperature the infrared sensors should provide an interface to inject ambient temperature. This was in past done via write to ambient temperature interface (in_temp_ambient_raw), but I think most people did not know about it. This solution introduces a new iio type of the CALIBAMBIENT which is hopefully more descriptive and more explicit about the purpose and capabilities of the sensors.

f2fs: support age threshold based garbage collection
There are several issues in current background GC algorithm: - valid blocks is one of key factors during cost overhead calculation, so if segment has less valid block, however even its age is young or it locates hot segment, CB algorithm will still choose the segment as victim, it's not appropriate. - GCed data/node will go to existing logs, no matter in-there datas' update frequency is the same or not, it may mix hot and cold data again. - GC alloctor mainly use LFS type segment, it will cost free segment more quickly. This patch introduces a new algorithm named age threshold based garbage collection to solve above issues, there are three steps mainly: 1. select a source victim: - set an age threshold, and select candidates beased threshold: e.g. 0 means youngest, 100 means oldest, if we set age threshold to 80 then select dirty segments which has age in range of [80, 100] as candiddates; - set candidate_ratio threshold, and select candidates based the ratio, so that we can shrink candidates to those oldest segments; - select target segment with fewest valid blocks in order to migrate blocks with minimum cost; 2. select a target victim: - select candidates beased age threshold; - set candidate_radius threshold, search candidates whose age is around source victims, searching radius should less than the radius threshold. - select target segment with most valid blocks in order to avoid migrating current target segment. 3. merge valid blocks from source victim into target victim with SSR alloctor. Test steps: - create 160 dirty segments: * half of them have 128 valid blocks per segment * left of them have 384 valid blocks per segment - run background GC Benefit: GC count and block movement count both decrease obviously: - Before: - Valid: 86 - Dirty: 1 - Prefree: 11 - Free: 6001 (6001) GC calls: 162 (BG: 220) - data segments : 160 (160) - node segments : 2 (2) Try to move 41454 blocks (BG: 41454) - data blocks : 40960 (40960) - node blocks : 494 (494) IPU: 0 blocks SSR: 0 blocks in 0 segments LFS: 41364 blocks in 81 segments - After: - Valid: 87 - Dirty: 0 - Prefree: 4 - Free: 6008 (6008) GC calls: 75 (BG: 76) - data segments : 74 (74) - node segments : 1 (1) Try to move 12813 blocks (BG: 12813) - data blocks : 12544 (12544) - node blocks : 269 (269) IPU: 0 blocks SSR: 12032 blocks in 77 segments LFS: 855 blocks in 2 segments Signed-off-by: Chao Yu <yuchao0@huawei.com> [Jaegeuk Kim: fix a bug along with pinfile in-mem segment & clean up] Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

fpga: dfl: create a dfl bus type to support DFL devices
A new bus type "dfl" is introduced for private features which are not initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these private features could be handled by separate driver modules. DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on enumeration. DFL drivers could be registered on this bus to match these DFL devices. They are matched by dfl type & feature_id.

fsi: aspeed: Support CFAM reset GPIO
Systems have a line for restting the remote CFAM. This is not part of the FSI master, but is associated with it, so it makes sense to include it in the master driver. This exposes a sysfs interface to reset the cfam, abstracting away the direction and polarity of the GPIO, as well as the timing of the reset pulse. Userspace will be blocked until the reset pulse is finished. The reset is hard coded to be in the range of (900, 1000) us. It was observed with a scope to regularly be just over 1ms. If the device tree property is not preset the driver will silently continue.

f2fs-for-5.9-rc1
In this round, we've added two small interfaces, 1) GC_URGENT_LOW mode for performance, and 2) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC mode allows Android to run some lower priority GCs in background, while new ioctl discards user information without race condition when the account is removed. In addition, some patches were merged to address latency-related issues. We've fixed some compression-related bug fixes as well as edge race conditions. Enhancement: - add GC_URGENT_LOW mode in gc_urgent - introduce F2FS_IOC_SEC_TRIM_FILE ioctl - bypass racy readahead to improve read latencies - shrink node_write lock coverage to avoid long latency Bug fix: - fix missing compression flag control, i_size, and mount option - fix deadlock between quota writes and checkpoint - remove inode eviction path in synchronous path to avoid deadlock - fix to wait GCed compressed page writeback - fix a kernel panic in f2fs_is_compressed_page - check page dirty status before writeback - wait page writeback before update in node page write flow - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry We've added some minor sanity checks and refactored trivial code blocks for better readability and debugging information. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl8xhqMACgkQQBSofoJI UNLYgA//WMoOqBACDuOWwYmgQ8oq4vrH2LOwssZF9/77vEfaHKc+TSq1il54lcUl MPEx7FK54CnfT8VLLR5ByobZFyH9FFeAw4FN4LBhcfE8jh8ysAGjeoZjwfcmJF6R cVKtn8ltUpgH3IEUuPjTiKkVNHfVJxuuL3zHbg1CEl+AkR6NJ/U9kNLwf7ZgPWq2 I0qwyXRlUIEChhyPZB+Y6RsdGjkeievKld56DMCgG73f4yHRO/yBcrfsN875sGdM ALL+mYiunMT6aXcfoiQiAjeImoNajuflI6Zso2Sk8Vl6sBj0QwAuEBF5x1Z5e1mt YVYNuC4ucqsDBKpOqtsPP0MFTC2T5Rr9wWXjqv+9TjN7zvJ8xx+zDWtQxvI2bpqB 4ZRxaJP45aThLYh/SEYDmj+ppyPtfLDeG0HzUkwMmuopf9eg+kxGPjBsZewgkCKg kmMKU0P7deGlkrWLUcz2vm0Lso+ieGm0IeLOQl9/rOLu3IQQFia0Vla7dLDgqF0P sz+udIiBztC3JPEmEZhfayA6P6e1TyWQUdquL08jp+DZD17gPqcaZDhHr62U5rmK 7zoiZqkR03SbNaFhBhhoVOaAVcAnF0pSIgqzkCa3dVXxp1QV+JfD9CGR9NFyiIqB HK5RPFskIUCg0K2LSaAKbyoFWa/fJ8ZD8/CbFWcnXfWzoaaSkmc= =PjaF -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two small interfaces: (a) GC_URGENT_LOW mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for security.

powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks.
- Support for a new faster system call ABI using the scv instruction on Power9
or later.
- Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
Power10 and future processors, leaving us with no way to implement the
functionality it requests. This risks breaking userspace, though we believe
it is unused in practice.
- A bug fix for, and then the removal of, our custom stack expansion checking.
We now allow stack expansion up to the rlimit, like other architectures.
- Remove the remnants of our (previously disabled) topology update code, which
tried to react to NUMA layout changes on virtualised systems, but was prone
to crashes and other problems.
- Add PMU support for Power10 CPUs.
- A change to our signal trampoline so that we don't unbalance the link stack
(branch return predictor) in the signal delivery path.
- Lots of other cleanups, refactorings, smaller features and so on as usual.

Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.
"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.
Other stuff in here that is interesting is:
- device probe log helper so that drivers can report problems in
a unified way easier.
- devres functions added
- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
incorrect sysfs file permissions
- documentation cleanups
- ability for debugfs to be present in the kernel, yet not
exposed to userspace. Needed for systems that want it
enabled, but do not trust users, so they can still use some
kernel functions that were otherwise disabled.
- other minor fixes and cleanups
The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.
All of these have been in linux-next with no reported issues.

It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again for a
while. Unless we decide to switch to asciidoc or something...:)
- Lots of typo fixes, warning fixes, and more.

Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq

ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory
subsystem and its drivers, starting out with a set of cleanup
patches.
A larger driver for the Tegra memory controller that was accidentally
missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware blobs
The tegra firmware driver gets extended to export some debug information
Various updates to i.MX firmware drivers, mostly cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space.
A new firmware based trusted platform module (fTPM) driver is added
based on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for identifying
a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device code.
There are also a number of updates to SoC specific drivers,
the main ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver

Merge tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC driver updates from Arnd Bergmann:
"A couple of subsystems have their own subsystem maintainers but choose
to have the code merged through the soc tree as upstream, as the code
tends to be used across multiple SoCs or has SoC specific drivers
itself:
- memory controllers:
Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
and its drivers, starting out with a set of cleanup patches.
A larger driver for the Tegra memory controller that was
accidentally missed for v5.8 is now added.
- reset controllers:
Only minor updates to drivers/reset this time
- firmware:
The "turris mox" firmware driver gains support for signed firmware
blobs The tegra firmware driver gets extended to export some debug
information Various updates to i.MX firmware drivers, mostly
cosmetic
- ARM SCMI/SCPI:
A new mechanism for platform notifications is added, among a number
of minor changes.
- optee:
Probing of the TEE bus is rewritten to better support detection of
devices that depend on the tee-supplicant user space. A new
firmware based trusted platform module (fTPM) driver is added based
on OP-TEE
- SoC attributes:
A new driver is added to provide a generic soc_device for
identifying a machine through the SMCCC ARCH_SOC_ID firmware
interface rather than by probing SoC family specific registers.
The series also contains some cleanups to the common soc_device
code.
There are also a number of updates to SoC specific drivers, the main
ones are:
- Mediatek cmdq driver gains a few in-kernel interfaces
- Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
support for additional SoC variants
- The Qualcomm GENI core code gains interconnect path voting and
performance level support, and integrating this into a number of
device drivers.
- A new driver for Samsung Exynos5800 voltage coupler for
- Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
specific device drivers
- Updates to the TI K3 Ring Accelerator driver"

powerpc/papr_scm: Fetch nvdimm performance stats from PHYP
Update papr_scm.c to query dimm performance statistics from PHYP via H_SCM_PERFORMANCE_STATS hcall and export them to user-space as PAPR specific NVDIMM attribute 'perf_stats' in sysfs. The patch also provide a sysfs ABI documentation for the stats being reported and their meanings. During NVDIMM probe time in papr_scm_nvdimm_init() a special variant of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of performance statistics is supported or not. If successful then a PHYP returns a maximum possible buffer length needed to read all performance stats. This returned value is stored in a per-nvdimm attribute 'stat_buffer_len'. The layout of request buffer for reading NVDIMM performance stats from PHYP is defined in 'struct papr_scm_perf_stats' and 'struct papr_scm_perf_stat'. These structs are used in newly introduced drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall. The sysfs access function perf_stats_show() uses value 'stat_buffer_len' to allocate a buffer large enough to hold all possible NVDIMM performance stats and passes it to drc_pmem_query_stats() to populate. Finally statistics reported in the buffer are formatted into the sysfs access function output buffer.

PM / devfreq: Add support delayed timer for polling mode
Until now, the devfreq driver using polling mode like simple_ondemand governor have used only deferrable timer for reducing the redundant power consumption. It reduces the CPU wake-up from idle due to polling mode which check the status of Non-CPU device. But, it has a problem for Non-CPU device like DMC device with DMA operation. Some Non-CPU device need to do monitor continuously regardless of CPU state in order to decide the proper next status of Non-CPU device. So, add support the delayed timer for polling mode to support the repetitive monitoring. The devfreq driver and user can select the kind of timer on either deferrable and delayed timer. For example, change the timer type of DMC device based on Exynos5422-based Odroid-XU3 as following: - If want to use deferrable timer as following: echo deferrable > /sys/class/devfreq/10c20000.memory-controller/timer - If want to use delayed timer as following: echo delayed > /sys/class/devfreq/10c20000.memory-controller/timer Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Reviewed-by: Lukasz Luba <lukasz.luba@arm.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> |

mei: add device kind to sysfs
Some of the mei device heads are not generic and have a specific purpose, we need to announce it to the user space so it is possible to detect the correct device node via matching attributes. Generic heads are marked as 'mei' while special purpose heads have their own names. Currently we are adding 'itouch' string for Intel IPTS 1.0, 2.0 devices. This is done via new sysfs attribute 'kind'.

ACPI: NFIT: Add runtime firmware activate support
Plumb the platform specific backend for the generic libnvdimm firmware activate interface. Register dimm level operations to arm/disarm activation, and register bus level operations to report the dynamic platform-quiesce time relative to the number of dimms armed for firmware activation. A new nfit-specific bus attribute "firmware_activate_noidle" is added to allow the activation to switch between platform enforced, and OS opportunistic device quiesce. In other words, let the hibernate cycle handle in-flight device-dma rather than the platform attempting to increase PCI-E timeouts and the like.

PM, libnvdimm: Add runtime firmware activation support
Abstract platform specific mechanics for nvdimm firmware activation behind a handful of generic ops. At the bus level ->activate_state() indicates the unified state (idle, busy, armed) of all DIMMs on the bus, and ->capability() indicates the system state expectations for activate. At the DIMM level ->activate_state() indicates the per-DIMM state, ->activate_result() indicates the outcome of the last activation attempt, and ->arm() attempts to transition the DIMM from 'idle' to 'armed'. A new hibernate_quiet_exec() facility is added to support firmware activation in an OS defined system quiesce state. It leverages the fact that the hibernate-freeze state wants to assert that a memory hibernation snapshot can be taken. This is in contrast to a platform firmware defined quiesce state that may forcefully quiet the memory controller independent of whether an individual device-driver properly supports hibernate-freeze. The libnvdimm sysfs interface is extended to support detection of a firmware activate capability. The mechanism supports enumeration and triggering of firmware activate, optionally in the hibernate_quiet_exec() context.

First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.

Merge tag 'iio-for-5.9a-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.
Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.
New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.
Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.
DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.
Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!
Cleanups and minor fixes.

powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show cpumask
Patch here adds a cpumask attr to hv_24x7 pmu along with ABI documentation. Primary use to expose the cpumask is for the perf tool which has the capability to parse the driver sysfs folder and understand the cpumask file. Having cpumask file will reduce the number of perf command line parameters (will avoid "-C" option in the perf tool command line). It can also notify the user which is the current cpu used to retrieve the counter data. command:# cat /sys/devices/hv_24x7/interface/cpumask 0 Signed-off-by: Kajol Jain <kjain@linux.ibm.com> Reviewed-by: Madhavan Srinivasan <maddy@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200709051836.723765-3-kjain@linux.ibm.com |

Export max_active_zones according to this new definition for NVMe Zoned Namespace devices, ZAC ATA devices (which are treated as SCSI devices by the kernel), and ZBC SCSI devices. Add the new max_active_zones member to struct request_queue, rather than as a queue limit, since this property cannot be split across stacking drivers.

driver core: Add waiting_for_supplier sysfs file for devices
This would be useful to check if a device is not probing because it's waiting for a supplier to be added and then linked to before it can probe. To reduce sysfs clutter, this file is added only if it can ever be 1. So, if fw_devlink is disabled or set to permissive, this file is not added. Also, this file is removed once the device probes as it's no longer relevant.

firmware: smccc: Add ARCH_SOC_ID support
SMCCC v1.2 adds a new optional function SMCCC_ARCH_SOC_ID to obtain a SiP defined SoC identification value. Add support for the same. Also using the SoC bus infrastructure, let us expose the platform specific SoC atrributes under sysfs. There are various ways in which it can be represented in shortened form for efficiency and ease of parsing for userspace. The chosen form is described in the ABI document.

thunderbolt: Add support for on-board retimers
USB4 spec specifies standard access to retimers (both on-board and cable) through USB4 port sideband access. This makes it possible to upgrade their firmware in the same way than we already do with the routers. This enumerates on-board retimers under each USB4 port when the link comes up and adds them to the bus under the router the retimer belongs to. Retimers are exposed in sysfs with name like <device>:<port>.<index> where device is the router the retimer belongs to, port is the USB4 port the retimer is connected to and index is the retimer index under that port (starting from 1). This applies to the upstream USB4 port as well so if there is on-board retimer between the port and the router it is also added accordingly. At this time we do not add cable retimers but there is no techincal restriction to do so in the future if needed. It is not clear whether it makes sense to upgrade their firmwares and at least Thunderbolt 3 cables it has not been done outside of lab environments. The sysfs interface is made to follow the router NVM upgrade to make it easy to extend the existing userspace (fwupd) to handle these as well.

powerpc/papr_scm: Fetch nvdimm health information from PHYP
Implement support for fetching nvdimm health information via
H_SCM_HEALTH hcall as documented in Ref[1]. The hcall returns a pair
of 64-bit bitmap, bitwise-and of which is then stored in
'struct papr_scm_priv' and subsequently partially exposed to
user-space via newly introduced dimm specific attribute
'papr/flags'. Since the hcall is costly, the health information is
cached and only re-queried, 60s after the previous successful hcall.
The patch also adds a documentation text describing flags reported by
the the new sysfs attribute 'papr/flags' is also introduced at
Documentation/ABI/testing/sysfs-bus-papr-pmem.

Pull x86 srbds fixes from Thomas Gleixner:
"The 9th episode of the dime novel "The performance killer" with the
subtitle "Slow Randomizing Boosts Denial of Service".
SRBDS is an MDS-like speculative side channel that can leak bits from
the random number generator (RNG) across cores and threads. New
microcode serializes the processor access during the execution of
RDRAND and RDSEED. This ensures that the shared buffer is overwritten
before it is released for reuse. This is equivalent to a full bus
lock, which means that many threads running the RNG instructions in
parallel have the same effect as the same amount of threads issuing a
locked instruction targeting an address which requires locking of two
cachelines at once.
The mitigation support comes with the usual pile of unpleasant
ingredients:
- command line options
- sysfs file
- microcode checks
- a list of vulnerable CPUs identified by model and stepping this
time which requires stepping match support for the cpu match logic.
- the inevitable slowdown of affected CPUs"

RDMA 5.8 merge window pull request
A few large, long discussed works this time. The RNBD block driver has
been posted for nearly two years now, and the removal of FMR has been a
recurring discussion theme for a long time. The usual smattering of
features and bug fixes.
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and a
mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block RDMA
device specific to ionos's cloud environment. It brings strong multipath
and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs and
drivers. FRWR should be preferred for at least a decade now.

Wenhu).
- Update cpufreq drivers:
* Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
* Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).

ACPI: DPTF: Add battery participant driver
This driver adds support for Dynamic Platform and Thermal Framework battery participant device support. These attributes are presented via sysfs interface under the platform device for the battery participant: $ls /sys/bus/platform/devices/INT3532:00/dptf_battery current_discharge_capbility_ma max_platform_power_mw no_load_voltage_mv high_freq_impedance_mohm max_steady_state_power_mw Refer to the documentation at Documentation/ABI/testing/sysfs-platform-dptf for details. Here the implementation reuses existing dptf-power.c as the motivation and processing is same. It also shares one ACPI method. Here this change is using participant type, "PTYP" method to identify and do different processing. By using participant type, create/delete either "dptf_power" or "dptf_battery" attribute group and send notifications. The particpant type for for the battery participant is 0x0C. ACPI methods description: PMAX (Intel(R) Dynamic Tuning Platform Max Power Supplied by Battery): This object evaluates to the maximum platform power that can be supported by the battery in milli watts. PBSS (Intel(R) Dynamic Tuning Power Battery Steady State): This object returns the max sustained power for battery in milli watts.

ACPI: DPTF: Additional sysfs attributes for power participant driver
Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.
prochot_confirm: (WO) Confirm EC about a prochot notification.
Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.
The ACPI methods used in this patch are as follows:
PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.
PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30 Reserved
31 0 – Not OK to de-assert PROCHOT
1 – OK to de-assert PROCHOT
PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0
Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

kernel/printk: add kmsg SEEK_CUR handling
Userspace libraries, e.g. glibc's dprintf(), perform a SEEK_CUR operation
over any file descriptor requested to make sure the current position isn't
pointing to junk due to previous manipulation of that same fd. And whenever
that fd doesn't have support for such operation, the userspace code expects
-ESPIPE to be returned.
However, when the fd in question references the /dev/kmsg interface, the
current kernel code state returns -EINVAL instead, causing an unexpected
behavior in userspace: in the case of glibc, when -ESPIPE is returned it
gets ignored and the call completes successfully, while returning -EINVAL
forces dprintf to fail without performing any action over that fd:
if (_IO_SEEKOFF (fp, (off64_t)0, _IO_seek_cur, _IOS_INPUT|_IOS_OUTPUT) ==
_IO_pos_BAD && errno != ESPIPE)
return NULL;
With this patch we make sure to return the correct value when SEEK_CUR is
requested over kmsg and also add some kernel doc information to formalize
this behavior.

soundwire: add Slave sysfs support
Expose MIPI DisCo Slave properties in sysfs. For Slave properties and Data Port 0, the attributes are managed with simple devm_ support. A Slave Device may have more than one Data Port (DPN), and each Data Port can be sink or source. The attributes are created dynamically using pre-canned macros, but still use devm_ with a name attribute group to avoid creating kobjects - as requested by GregKH. In the _show function, we use container_of() to retrieve port number and direction required to extract the information. Audio modes are not supported for now.

habanalabs: support clock gating enable/disable
In Gaudi there is a feature of clock gating certain engines. Therefore, add this property to the device structure. In addition, due to a limitation of this feature, the driver needs to dynamically enable or disable this feature during run-time. Therefore, add ASIC interface functions to enable/disable this function from the common code. Moreover, this feature must be turned off when the user wishes to debug the ASIC by reading/writing registers and/or memory through the driver's debugfs. Therefore, add an option to enable/disable clock gating via the debugfs interface. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> |

w1_therm: adding bulk read support to trigger multiple conversion on bus
Adding bulk read support:
Sending a 'trigger' command in the dedicated sysfs entry of bus master
device send a conversion command for all the slaves on the bus. The sysfs
entry is added as soon as at least one device supporting this feature
is detected on the bus.
The behavior of the sysfs reading temperature on the device is as follow:
* If no bulk read pending, trigger a conversion on the device, wait for
the conversion to be done, read the temperature in device RAM
* If a bulk read has been trigger, access directly the device RAM
This behavior is the same on the 2 sysfs entries ('temperature' and
'w1_slave').
Reading the therm_bulk_read sysfs give the status of bulk operations:
* '-1': conversion in progress on at least 1 sensor
* '1': conversion complete but at least one sensor has not been read yet
* '0': no bulk operation. Reading temperature on ecah device will trigger
a conversion
As not all devices support bulk read feature, it has been added in device
family structure.
The attribute is set at master level as soon as a supporting device is
discover. It is removed when the last supported device leave the bus.
The count of supported device is kept with the static counter
bulk_read_device_counter.
A strong pull up is apply on the line if at least one device required it.
The duration of the pull up is the max time required by a device on the

w1_therm: adding alarm sysfs entry
Adding device alarms settings by a dedicated sysfs entry alarms (RW): read or write TH and TL in the device RAM. Checking devices in alarm state could be performed using the master search command. As alarms temperature level are store in a 8 bit register on the device and are signed values, a safe cast shall be performed using the min and max temperature that device are able to measure. This is done by int_to_short inline function. A 'write_data' field is added in the device structure, to bind the correct writing function, as some devices may have 2 or 3 bytes RAM. Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: optimizing temperature read timings
Optimizing temperature reading by reducing waiting conversion time according to device resolution settings, as per device specification. This is device dependent as not all the devices supports resolution setting, so it has been added in device family structures. The process to read the temperature on the device has been adapted in a new function 'convert_t()', which replace the former 'read_therm()', is introduce to deal with this timing. Strong pull up is also applied during the required time, according to device power status needs and 'strong_pullup' module parameter. 'temperature_from_RAM()' function is introduced to get the correct temperature computation (device dependent) from device RAM data. An new sysfs entry has been added to ouptut only temperature. The old entry w1_slave has been kept for compatibility, without changing its output format. Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: adding eeprom sysfs entry
The driver implement 2 hardware functions to access device RAM: * copy_scratchpad * recall_scratchpad They act according to device specifications.

w1_therm: adding resolution sysfs entry
Adding resolution sysfs entry (RW) to get or set the device resolution Write values are managed as follow: * '9..12': resolution to set in bit * Anything else: do nothing Read values are : * '9..12': device resolution in bit * '-xx': xx is kernel error when reading the resolution Only supported devices will show the sysfs entry. A new family has been created for DS18S20 devices as they do not implement resolution feature. The resolution of each device is check when the device is discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'. The status is stored in the device structure w1_therm_family_data so that the driver always knows the resolution of each device, which could be used later to determine the required conversion duration (resolution dependent). The resolution is re evaluate each time a user read or write the sysfs entry. To avoid looping through the w1_therm_families at run time, the pointer 'specific_functions' is set up to the correct 'w1_therm_family_converter' when the slave is added (which mean when it is discovered by the master). This initialization is done by a helper function 'device_family(struct w1_slave *sl)', and a dedicated macro 'SLAVE_SPECIFIC_FUNC(sl)' allow the access to the specific function of the slave device. 'read_scratchpad' and 'write_scratchpad' are the hardware functions to access the device RAM, as per protocol specification. It cancel the former 'precision' functions, which was only set and never read (so not stored in the device struct). Updating Documentation/ABI/testing/sysfs-driver-w1_therm accordingly.

w1_therm: adding ext_power sysfs entry
Adding ext_power sysfs entry (RO). Return the power status of the device: - 0: device parasite powered - 1: device externally powered - xx: xx is kernel error The power status of each device is check when the device is discover by the bus master, in 'w1_therm_add_slave(struct w1_slave *)'. The status is stored in the device structure w1_therm_family_data so that the driver always knows the power state of each device, which could be used later to determine the required strong pull up to apply on the line. The power status is re evaluate each time the sysfs ext_power read by a user. The hardware function 'read_powermode(struct w1_slave *sl)' act just as per device specifications, sending W1_READ_PSUPPLY command on the bus, and issue a read time slot, reading only one bit.

platform/x86: Add Slim Bootloader firmware update signaling driver
Slim Bootloader(SBL) is a small open-source boot firmware, designed for running on certain Intel platforms. SBL can be thought-of as fulfilling the role of a minimal BIOS implementation, i.e initializing the hardware and booting Operating System. Since SBL is not UEFI compliant, firmware update cannot be triggered using standard UEFI runtime services. Further considering performance impact, SBL doesn't look for a firmware update image on every reset and does so only when firmware update signal is asserted. SBL exposes an ACPI-WMI device which comes up in sysfs as /sys/bus/wmi/44FADEB1xxx and this driver adds a "firmware_update_request" device attribute. This attribute normally has a value of 0 and userspace can signal SBL to update firmware, on next reboot, by writing a value of 1 like: echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request This driver only implements a signaling mechanism, the actual firmware update process and various details like firmware update image format, firmware image location etc are defined by SBL and are not in the scope of this driver.

fpga: dfl: fme: add performance reporting support
This patch adds support for performance reporting private feature
for FPGA Management Engine (FME). Now it supports several different
performance counters, including 'basic', 'cache', 'fabric', 'vtd'
and 'vtd_sip'. It allows user to use standard linux tools to access
these performance counters.
e.g. List all events by "perf list"
perf list | grep fme
dfl_fme0/cache_read_hit/ [Kernel PMU event]
dfl_fme0/cache_read_miss/ [Kernel PMU event]
...
dfl_fme0/fab_mmio_read/ [Kernel PMU event]
dfl_fme0/fab_mmio_write/ [Kernel PMU event]
...
dfl_fme0/fab_port_mmio_read,portid=?/ [Kernel PMU event]
dfl_fme0/fab_port_mmio_write,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_port_devtlb_1g_fill,portid=?/ [Kernel PMU event]
dfl_fme0/vtd_port_devtlb_2m_fill,portid=?/ [Kernel PMU event]
...
dfl_fme0/vtd_sip_iotlb_1g_hit/ [Kernel PMU event]
dfl_fme0/vtd_sip_iotlb_1g_miss/ [Kernel PMU event]
...
dfl_fme0/clock [Kernel PMU event]
...
e.g. check increased counter value after run one application using
"perf stat" command.
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_mmio_write/ ./test
Performance counter stats for './test':
1 dfl_fme0/fab_mmio_read/
2 dfl_fme0/fab_mmio_write/
1.009496520 seconds time elapsed
Please note that fabric counters support both fab_* and fab_port_*, but
actually they are sharing one set of performance counters in hardware.
If user wants to monitor overall data events on fab_* then fab_port_*
can't be supported at the same time, see example below:
perf stat -e dfl_fme0/fab_mmio_read/,dfl_fme0/fab_port_mmio_write,portid=0/
Performance counter stats for 'system wide':
0 dfl_fme0/fab_mmio_read/
<not supported> dfl_fme0/fab_port_mmio_write,portid=0/

New microcode serializes the processor access during the execution of RDRAND and RDSEED. This ensures that the shared buffer is overwritten before it is released for reuse. While it is present on all affected CPU models, the microcode mitigation is not needed on models that enumerate ARCH_CAPABILITIES[MDS_NO] in the cases where TSX is not supported or has been disabled with TSX_CTRL. The mitigation is activated by default on affected processors and it increases latency for RDRAND and RDSEED instructions. Among other effects this will reduce throughput from /dev/urandom. * Enable administrator to configure the mitigation off when desired using either mitigations=off or srbds=off. * Export vulnerability status via sysfs * Rename file-scoped macros to apply for non-whitelist table initializations. [ bp: Massage, - s/VULNBL_INTEL_STEPPING/VULNBL_INTEL_STEPPINGS/g, - do not read arch cap MSR a second time in tsx_fused_off() - just pass it in, - flip check in cpu_set_bug_bits() to save an indentation level, - reflow comments. jpoimboe: s/Mitigated/Mitigation/ in user-visible strings tglx: Dropped the fused off magic for now ] Signed-off-by: Mark Gross <mgross@linux.intel.com> Signed-off-by: Borislav Petkov <bp@suse.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Tony Luck <tony.luck@intel.com> Reviewed-by: Pawan Gupta <pawan.kumar.gupta@linux.intel.com> Reviewed-by: Josh Poimboeuf <jpoimboe@redhat.com> Tested-by: Neelima Krishnan <neelima.krishnan@intel.com> |

f2fs-for-5.7-rc1
In this round, we've mainly focused on fixing bugs and addressing issues in
recently introduced compression support.
Enhancement:
- add zstd support, and set LZ4 by default
- add ioctl() to show # of compressed blocks
- show mount time in debugfs
- replace rwsem with spinlock
- avoid lock contention in DIO reads
Some major bug fixes wrt compression:
- compressed block count
- memory access and leak
- remove obsolete fields
- flag controls
Other bug fixes and clean ups:
- fix overflow when handling .flags in inode_info
- fix SPO issue during resize FS flow
- fix compression with fsverity enabled
- potential deadlock when writing compressed pages
- show missing mount options

powerpc updates for 5.7
- A large series from Nick for 64-bit to further rework our exception vectors,
and rewrite portions of the syscall entry/exit and interrupt return in C. The
result is much easier to follow code that is also faster in general.
- Cleanup of our ptrace code to split various parts out that had become badly
intertwined with #ifdefs over the years.
- Changes to our NUMA setup under the PowerVM hypervisor which should
hopefully avoid non-sensical topologies which can lead to warnings from the
workqueue code and other problems.
- MAINTAINERS updates to remove some of our old orphan entries and update the
status of others.
- Quite a few other small changes and fixes all over the map.

intel_th: msu: Make stopping the trace optional
Some use cases prefer to keep collecting the trace data into the last available window while the other windows are being offloaded instead of stopping the trace.

serial: core: Allow detach and attach serial device for console
In the future we would like to disable power management on the serial devices used as kernel consoles to avoid weird behaviour in some cases. However, disabling PM may prevent system to go to deep sleep states, which in its turn leads to the higher power consumption. Tony Lindgren proposed a work around, i.e. allow user to detach such consoles to make PM working again. In case user wants to see what's going on, it also provides a mechanism to attach console back.

uacce: add uacce driver
Uacce (Unified/User-space-access-intended Accelerator Framework) targets to
provide Shared Virtual Addressing (SVA) between accelerators and processes.
So accelerator can access any data structure of the main cpu.
This differs from the data sharing between cpu and io device, which share
only data content rather than address.
Since unified address, hardware and user space of process can share the
same virtual address in the communication.
Uacce create a chrdev for every registration, the queue is allocated to
the process when the chrdev is opened. Then the process can access the
hardware resource by interact with the queue file. By mmap the queue
file space to user space, the process can directly put requests to the
hardware without syscall to the kernel space.
The IOMMU core only tracks mm<->device bonds at the moment, because it
only needs to handle IOTLB invalidation and PASID table entries. However
uacce needs a finer granularity since multiple queues from the same
device can be bound to an mm. When the mm exits, all bound queues must
be stopped so that the IOMMU can safely clear the PASID table entry and
reallocate the PASID.
An intermediate struct uacce_mm links uacce devices and queues.
Note that an mm may be bound to multiple devices but an uacce_mm
structure only ever belongs to a single device, because we don't need
anything more complex (if multiple devices are bound to one mm, then
we'll create one uacce_mm for each bond).

powerpc/fadump: Reorganize /sys/kernel/fadump_* sysfs files
As the number of FADump sysfs files increases it is hard to manage all of them inside /sys/kernel directory. It's better to have all the FADump related sysfs files in a dedicated directory /sys/kernel/fadump. But in order to maintain backward compatibility a symlink has been added for every sysfs that has moved to new location. As the FADump sysfs files are now part of a dedicated directory there is no need to prefix their name with fadump_, hence sysfs file names are also updated. For example fadump_enabled sysfs file is now referred as enabled. Also consolidate ABI documentation for all the FADump sysfs files in a single file Documentation/ABI/testing/sysfs-kernel-fadump.

usb: typec: Allow power role swapping even without USB PD
Even though originally the USB Type-C Specification did not describe the steps for power role swapping without USB PD contract in place, it did not actually mean power role swap without USB PD was not allowed. The USB Type-C Specification did not clearly separate the data and power roles until in the release 1.2 which is why there also were no clear steps for the scenario where only the power role was swapped without USB PD contract before that. Since in the latest version of the specification the power role swap without USB PD is now clearly mentioned as allowed operation, removing the check that prevented power role swap without USB PD support.

f2fs-for-5.6
In this series, we've implemented transparent compression experimentally. It supports LZO and LZ4, but will add more later as we investigate in the field more. At this point, the feature doesn't expose compressed space to user directly in order to guarantee potential data updates later to the space. Instead, the main goal is to reduce data writes to flash disk as much as possible, resulting in extending disk life time as well as relaxing IO congestion. Alternatively, we're also considering to add ioctl() to reclaim compressed space and show it to user after putting the immutable bit. Enhancement: - add compression support - avoid unnecessary locks in quota ops - harden power-cut scenario for zoned block devices - use private bio_set to avoid IO congestion - replace GC mutex with rwsem to serialize callers Bug fix: - fix dentry consistency and memory corruption in rename()'s error case - fix wrong swap extent reports - fix casefolding bugs - change lock coverage to avoid deadlock - avoid GFP_KERNEL under f2fs_lock_op And, we've cleaned up sysfs entries to prepare no debugfs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl4zInwACgkQQBSofoJI UNL4Tg/+JBbVEFa3IUBGMdbjfgd/g0Jye++iMAYYGRWT6Ll/IGcHRV9NunITjgWU mBZqdhI28kXeiGCcewB1ZvivjLx22X4n6yevHk2B5A6PNe9IDCHi0HOAhJJHkjPH ecv2L+vX3Oj4y0+H7JNz9Fo3OIPJvMPtCQWlg1z+VQyhB85zNP7fZlvvIY4tG8yw ERo0YNotLqwcF1BxCwNbAhV3aJGDxar+MI//yNzpiwDX7IptVpqestfcoIYc9kKL 4kSWRyEIGwcuIeyoM6aofGS9t4Z/Oe/gdqcxNr6l5n0Q/tMTpb4b/fJFGNr6RRx9 X9NQo8flkQb2DEIOP0DVpO2aPebzsVtzg3LZUOLA83+wCHfwINtHai2Dy2zDJ2my BrVdou8fe2oxoaYihJg/Tz9cd0nA/6mZArtpYvDImAmX/xuGOvVk9zZkXNwc9nVX EyVzy0vW4lA6gAIJ95aG6DDhJcAtVoy0MhBRWG92Pufxhn9aW24AV63ChWUf9DRx /3RqpMAuQ3UC2gOxXKKnr54lsdhUIMn/y9sjROkVvQ1BvgRVxO8I4GFvMHMKv9pR 9KXiVRdzyYERyoL4+MF7A2zTnw+RHL4RVILa85p2ALGy2jQ1UuNUQi0BN9x2u1v8 S1ifNNX8SwOP+83ImFJhhn3HybpFQ45aLO3F7ZjKBQAnufJu+xw= =zeoY -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this series, we've implemented transparent compression experimentally.

xen/blkback: Squeeze page pools if a memory pressure is detected
Each `blkif` has a free pages pool for the grant mapping. The size of
the pool starts from zero and is increased on demand while processing
the I/O requests. If current I/O requests handling is finished or 100
milliseconds has passed since last I/O requests handling, it checks and
shrinks the pool to not exceed the size limit, `max_buffer_pages`.
Therefore, host administrators can cause memory pressure in blkback by
attaching a large number of block devices and inducing I/O. Such
problematic situations can be avoided by limiting the maximum number of
devices that can be attached, but finding the optimal limit is not so
easy. Improper set of the limit can results in memory pressure or a
resource underutilization. This commit avoids such problematic
situations by squeezing the pools (returns every free page in the pool
to the system) for a while (users can set this duration via a module
parameter) if memory pressure is detected.
Discussions
===========
The `blkback`'s original shrinking mechanism returns only pages in the
pool which are not currently be used by `blkback` to the system. In
other words, the pages that are not mapped with granted pages. Because
this commit is changing only the shrink limit but still uses the same
freeing mechanism it does not touch pages which are currently mapping
grants.
Once memory pressure is detected, this commit keeps the squeezing limit
for a user-specified time duration. The duration should be neither too
long nor too short. If it is too long, the squeezing incurring overhead
can reduce the I/O performance. If it is too short, `blkback` will not
free enough pages to reduce the memory pressure. This commit sets the
value as `10 milliseconds` by default because it is a short time in
terms of I/O while it is a long time in terms of memory operations.
Also, as the original shrinking mechanism works for at least every 100
milliseconds, this could be a somewhat reasonable choice. I also tested
other durations (refer to the below section for more details) and
confirmed that 10 milliseconds is the one that works best with the test.
That said, the proper duration depends on actual configurations and
workloads. That's why this commit allows users to set the duration as a
module parameter.
Memory Pressure Test
====================
To show how this commit fixes the memory pressure situation well, I
configured a test environment on a xen-running virtualization system.
On the `blkfront` running guest instances, I attach a large number of
network-backed volume devices and induce I/O to those. Meanwhile, I
measure the number of pages that swapped in (pswpin) and out (pswpout)
on the `blkback` running guest. The test ran twice, once for the
`blkback` before this commit and once for that after this commit. As
shown below, this commit has dramatically reduced the memory pressure:
pswpin pswpout
before 76,672 185,799
after 867 3,967
Optimal Aggressive Shrinking Duration
-------------------------------------
To find a best squeezing duration, I repeated the test with three
different durations (1ms, 10ms, and 100ms). The results are as below:
duration pswpin pswpout
1 707 5,095
10 867 3,967
100 362 3,348
As expected, the memory pressure decreases as the duration increases,
but the reduction become slow from the `10ms`. Based on this results, I
chose the default duration as 10ms.
Performance Overhead Test
=========================
This commit could incur I/O performance degradation under severe memory
pressure because the squeezing will require more page allocations per
I/O. To show the overhead, I artificially made a worst-case squeezing
situation and measured the I/O performance of a `blkfront` running
guest.
For the artificial squeezing, I set the `blkback.max_buffer_pages` using
the `/sys/module/xen_blkback/parameters/max_buffer_pages` file. In this
test, I set the value to `1024` and `0`. The `1024` is the default
value. Setting the value as `0` is same to a situation doing the
squeezing always (worst-case).
If the underlying block device is slow enough, the squeezing overhead
could be hidden. For the reason, I use a fast block device, namely the
rbd[1]:
# xl block-attach guest phy:/dev/ram0 xvdb w
For the I/O performance measurement, I run a simple `dd` command 5 times
directly to the device as below and collect the 'MB/s' results.
$ for i in {1..5}; do dd if=/dev/zero of=/dev/xvdb \
bs=4k count=$((256*512)); sync; done
The results are as below. 'max_pgs' represents the value of the
`blkback.max_buffer_pages` parameter.
max_pgs Min Max Median Avg Stddev
0 417 423 420 419.4 2.5099801
1024 414 425 416 417.8 4.4384682
No difference proven at 95.0% confidence
In short, even worst case squeezing on ramdisk based fast block device
makes no visible performance degradation. Please note that this is just
a very simple and minimal test. On systems using super-fast block
devices and a special I/O workload, the results might be different. If
you have any doubt, test on your machine with your workload to find the
optimal squeezing duration for you.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull IMA updates from Mimi Zohar:
"Two new features - measuring certificates and querying IMA for a file
hash - and three bug fixes:
- Measuring certificates is like the rest of IMA, based on policy,
but requires loading a custom policy. Certificates loaded onto a
keyring, for example during early boot, before a custom policy has
been loaded, are queued and only processed after loading the custom
policy.
- IMA calculates and caches files hashes. Other kernel subsystems,
and possibly kernel modules, are interested in accessing these
cached file hashes.
The bug fixes prevent classifying a file short read (e.g. shutdown) as
an invalid file signature, add a missing blank when displaying the
securityfs policy rules containing LSM labels, and, lastly, fix the
handling of the IMA policy information for unknown LSM labels"

net: phy: Maintain MDIO device and bus statistics
We maintain global statistics for an entire MDIO bus, as well as broken down, per MDIO bus address statistics. Given that it is possible for MDIO devices such as switches to access MDIO bus addresses for which there is not a mdio_device instance created (therefore not a a corresponding device directory in sysfs either), we also maintain per-address statistics under the statistics folder. The layout looks like this: /sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_<addr> errors_<addr> writes_<addr> reads_<addr> When a mdio_device instance is registered, a statistics/ folder is created with the tranfers, errors, writes and reads attributes which point to the appropriate MDIO bus statistics structure. Statistics are 64-bit unsigned quantities and maintained through the u64_stats_sync.h helper functions.

PM: suspend: Add sysfs attribute to control the "sync on suspend" behavior
The sysfs attribute `/sys/power/sync_on_suspend` controls, whether or not filesystems are synced by the kernel before system suspend. Congruously, the behaviour of build-time switch CONFIG_SUSPEND_SKIP_SYNC is slightly changed: It now defines the run-tim default for the new sysfs attribute `/sys/power/sync_on_suspend`. The run-time attribute is added because the existing corresponding build-time Kconfig flag for (`CONFIG_SUSPEND_SKIP_SYNC`) is not flexible enough. E.g. Linux distributions that provide pre-compiled kernels usually want to stick with the default (sync filesystems before suspend) but under special conditions this needs to be changed. One example for such a special condition is user-space handling of suspending block devices (e.g. using `cryptsetup luksSuspend` or `dmsetup suspend`) before system suspend. The Kernel trying to sync filesystems after the underlying block device already got suspended obviously leads to dead-locks. Be aware that you have to take care of the filesystem sync yourself before suspending the system in those scenarios. Signed-off-by: Jonas Meurer <jonas@freesources.org> Signed-off-by: Rafael J.

xen-pciback: optionally allow interrupt enable flag writes
QEMU running in a stubdom needs to be able to set INTX_DISABLE, and the
MSI(-X) enable flags in the PCI config space. This adds an attribute
'allow_interrupt_control' which when set for a PCI device allows writes
to this flag(s). The toolstack will need to set this for stubdoms.
When enabled, guest (stubdomain) will be allowed to set relevant enable
flags, but only one at a time - i.e. it refuses to enable more than one
of INTx, MSI, MSI-X at a time.
This functionality is needed only for config space access done by device
model (stubdomain) serving a HVM with the actual PCI device. It is not
necessary and unsafe to enable direct access to those bits for PV domain
with the device attached. For PV domains, there are separate protocol
messages (XEN_PCI_OP_{enable,disable}_{msi,msix}) for this purpose.
Those ops in addition to setting enable bits, also configure MSI(-X) in
dom0 kernel - which is undesirable for PCI passthrough to HVM guests.
This should not introduce any new security issues since a malicious
guest (or stubdom) can already generate MSIs through other ways, see
[1] page 8. Additionally, when qemu runs in dom0, it already have direct
access to those bits.
This is the second iteration of this feature. First was proposed as a
direct Xen interface through a new hypercall, but ultimately it was
rejected by the maintainer, because of mixing pciback and hypercalls for
PCI config space access isn't a good design. Full discussion at [2].

iio: buffer-dmaengine: Report buffer length requirements
The dmaengine buffer has some length alignment requirements that can differ from platform to platform. If the length alignment requirements are not met unexpected behavior like dropping of samples can occur. Currently these requirements are not reported and applications need to know the requirements of the platform by some out-of-band means. Add a new buffer attribute that reports the length alignment requirements called `length_align_bytes`. The reported length alignment is in bytes that means the buffer length alignment in sample sets depends on the number of enabled channels and the bytes per channel. Applications using this attribute to determine the buffer size requirements need to consider this.

cpuidle: Allow idle states to be disabled by default
In certain situations it may be useful to prevent some idle states
from being used by default while allowing user space to enable them
later on.
For this purpose, introduce a new state flag, CPUIDLE_FLAG_OFF, to
mark idle states that should be disabled by default, make the core
set CPUIDLE_STATE_DISABLED_BY_USER for those states at the
initialization time and add a new state attribute in sysfs,
"default_status", to inform user space of the initial status of
the given idle state ("disabled" if CPUIDLE_FLAG_OFF is set for it,
"enabled" otherwise).

platform/mellanox: fix the mlx-bootctl sysfs
This is a follow-up commit for the sysfs attributes to change
from DRIVER_ATTR to DEVICE_ATTR according to some initial comments.
In such case, it's better to point the sysfs path to the device
itself instead of the driver. The ABI document is also updated.
Fixes:

IMA: Add support to limit measuring keys
Limit measuring keys to those keys being loaded onto a given set of keyrings only and when the user id (uid) matches if uid is specified in the policy. This patch defines a new IMA policy option namely "keyrings=" that can be used to specify a set of keyrings. If this option is specified in the policy for "measure func=KEY_CHECK" then only the keys loaded onto a keyring given in the "keyrings=" option are measured. If uid is specified in the policy then the key is measured only if the current user id matches the one specified in the policy. Added a new parameter namely "keyring" (name of the keyring) to process_buffer_measurement(). The keyring name is passed to ima_get_action() to determine the required action. ima_match_rules() is updated to check keyring in the policy, if specified, for KEY_CHECK function.

Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
- More RST conversions; those are slowing down as we run out of things to
convert, but we're a ways from done still.
- Dan's "maintainer profile entry" work landed at last. Now we just need
to get maintainers to fill in the profiles...
- A reworking of the parallel build setup to work better with a variety of
systems (and to not take over huge systems entirely in particular).
- The MAINTAINERS file is now converted to RST during the build.
Hopefully nobody ever tries to print this thing, or they will need to
load a lot of paper.
- A script and documentation making it easy for maintainers to add Link:
tags at commit time.
Also included is the removal of a bunch of spurious CR characters.

powerpc updates for 5.5
Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines. The
firmware support is still in development, so the code here won't actually
activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict it to
read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop
into xmon and modify kernel data, such as the lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work
with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management) driver to
make it behave more like other balloon drivers and enable some cleanups of
generic mm code.
- A series of fixes to our hardware breakpoint support to properly handle
unaligned watchpoint addresses.
Plus a bunch of other smaller improvements, fixes and cleanups.

f2fs: expose main_blkaddr in sysfs
Expose in /sys/fs/f2fs/<blockdev>/main_blkaddr the block address where the main area starts. This allows user mode programs to determine: - That pinned files that are made exclusively of fully allocated 2MB segments will never be unpinned by the file system. - Where the main area starts. This is required by programs that want to verify if a file is made exclusively of 2MB f2fs segments, the alignment boundary for segments starts at this address. Testing for 2MB alignment relative to the start of the device is incorrect, because for some filesystems main_blkaddr is not at a 2MB boundary relative to the start of the device. The entry will be used when validating reliable pinning file feature proposed by "f2fs: support aligned pinned file".

PCI/ASPM: Add sysfs attributes for controlling ASPM link states
Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM, Clock PM, and L1 PM Substates. The new attributes are: /sys/devices/pci*/.../link/clkpm /sys/devices/pci*/.../link/l0s_aspm /sys/devices/pci*/.../link/l1_aspm /sys/devices/pci*/.../link/l1_1_aspm /sys/devices/pci*/.../link/l1_2_aspm /sys/devices/pci*/.../link/l1_1_pcipm /sys/devices/pci*/.../link/l1_2_pcipm An attribute is only visible if both ends of the Link leading to the device support the state. Writing y/1/on to the file enables the state; n/0/off disables it. These attributes can be used to tune the power/performance tradeoff for individual devices.

block: add iostat counters for flush requests
Requests that triggers flushing volatile writeback cache to disk (barriers) have significant effect to overall performance. Block layer has sophisticated engine for combining several flush requests into one. But there is no statistics for actual flushes executed by disk. Requests which trigger flushes usually are barriers - zero-size writes. This patch adds two iostat counters into /sys/class/block/$dev/stat and /proc/diskstats - count of completed flush requests and their total time.

watchdog: make nowayout sysfs file writable
It can be useful to delay setting the nowayout feature for a watchdog device. Moreover, not every driver (notably gpio_wdt) implements a nowayout module parameter/otherwise respects CONFIG_WATCHDOG_NOWAYOUT, and modifying those drivers carries a risk of causing a regression for someone who has two watchdog devices, sets CONFIG_WATCHDOG_NOWAYOUT and somehow relies on the gpio_wdt driver being ignorant of that (i.e., allowing one to gracefully close a gpio_wdt but not the other watchdog in the system). So instead, simply make the nowayout sysfs file writable. Obviously, setting nowayout is a one-way street.

ima: Check against blacklisted hashes for files with modsig
Asymmetric private keys are used to sign multiple files. The kernel currently supports checking against blacklisted keys. However, if the public key is blacklisted, any file signed by the blacklisted key will automatically fail signature verification. Blacklisting the public key is not fine enough granularity, as we might want to only blacklist a particular file. This patch adds support for checking against the blacklisted hash of the file, without the appended signature, based on the IMA policy. It defines a new policy option "appraise_flag=check_blacklist". In addition to the blacklisted binary hashes stored in the firmware "dbx" variable, the Linux kernel may be configured to load blacklisted binary hashes onto the .blacklist keyring as well. The following example shows how to blacklist a specific kernel module hash. $ sha256sum kernel/kheaders.ko 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 kernel/kheaders.ko $ grep BLACKLIST .config CONFIG_SYSTEM_BLACKLIST_KEYRING=y CONFIG_SYSTEM_BLACKLIST_HASH_LIST="blacklist-hash-list" $ cat certs/blacklist-hash-list "bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3" Update the IMA custom measurement and appraisal policy rules (/etc/ima-policy): measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig After building, installing, and rebooting the kernel: 545660333 ---lswrv 0 0 \_ blacklist: bin:77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 measure func=MODULE_CHECK template=ima-modsig appraise func=MODULE_CHECK appraise_flag=check_blacklist appraise_type=imasig|modsig modprobe: ERROR: could not insert 'kheaders': Permission denied 10 0c9834db5a0182c1fb0cdc5d3adcf11a11fd83dd ima-sig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0-rc3+/kernel/kernel/kheaders.ko 10 82aad2bcc3fa8ed94762356b5c14838f3bcfa6a0 ima-modsig sha256:3bc6ed4f0b4d6e31bc1dbc9ef844605abc7afdc6d81a57d77a1ec9407997c40 2 /usr/lib/modules/5.4.0rc3+/kernel/kernel/kheaders.ko sha256:77fa889b3 5a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 3082029a06092a864886f70d010702a082028b30820287020101310d300b0609608648 016503040201300b06092a864886f70d01070131820264.... 10 25b72217cc1152b44b134ce2cd68f12dfb71acb3 ima-buf sha256:8b58427fedcf8f4b20bc8dc007f2e232bf7285d7b93a66476321f9c2a3aa132 b blacklisted-hash 77fa889b35a05338ec52e51591c1b89d4c8d1c99a21251d7c22b1a8642a6bad3 Signed-off-by: Nayna Jain <nayna@linux.ibm.com> [zohar@linux.ibm.com: updated patch description] Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/1572492694-6520-8-git-send-email-zohar@linux.ibm.com |

thunderbolt: Changes for v5.5 merge window
This adds Thunderbolt 3 support for the software connection manager. It is currently only used in Apple systems. Previously the driver started the firmware connection manager on those but it is not necessary anymore with these patches (we still leave user an option to start the firmware in case there are problems with the software connection manager). This includes: - Expose 'generation' attribute under each device in sysfs - Converting register names to follow the USB4 spec. - Lane bonding support - Expose link speed and width in sysfs - Display Port handshake needed for Titan Ridge devices - Display Port pairing and resource management - Display Port bandwidth management -----BEGIN PGP SIGNATURE----- iQJUBAABCgA+FiEEVTdhRGBbNzLrSUBaAP2fSd+ZWKAFAl3ED00gHG1pa2Eud2Vz dGVyYmVyZ0BsaW51eC5pbnRlbC5jb20ACgkQAP2fSd+ZWKChGw//UJdZcc1uJWhw nXoCzJzgseBXCigwE/B44q6P//aqh3Ku9gexApeQC4KMuRWHx2OGzhI8Xji/wBV0 z9miqRNYseUMwAkiYIvHmZFICJZfBkawenItaoI8sDzRD7vKz39puHDx1icfa4jL INAe0GiMtaJtqbVIq4FPz77kuGhmMhEdJcbPbLqTm58gqtXW66K2L1XwDHi5bQSa rnw/uUPr9jdek2KfT0nbGwIgP+7+26Igm/JuZcTTFpG9kymy6faukdMHQXiKThM0 E5azC9BDz80HKiFcCqBjCH165iTxmhrvwOPi9SnTBBi59Xd6P4/NewsT84mtAVCA p4SgXzbfCLdojhiBbGTQYan91kBSaBPkjsnhy5hthWtPFKj2ELTqv+WX32kUSHyc LFgrC4eu4028Iv8xngMAOzle3+0prc6Gr5248te4yUx3OXPxMiN8AbDw41aUt5dK JnKeedNw+ZhvUzN0nOs29gBURSmr4qRpj7T/ZmZRPpe0qx+pSVMa17rBTo3Qk45/ lZCLVmVwC42DXUmWOZdYvAijWwF/z0L3Rsk38xGs+7DjbFepN1XaUi5cuoMmaqZp PJ9ogn19GtazS8Anwawy99ry/2EjqeGiSrW42Zzk2w8hktW6IiSrWQppMcZGmhvW c6Lz04I42ZtW3UjnmSe4WIXZtLvMz/8= =LiDm -----END PGP SIGNATURE----- Merge tag 'thunderbolt-for-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt into char-misc-next Mika writes: thunderbolt: Changes for v5.5 merge window This adds Thunderbolt 3 support for the software connection manager.

mei: add trc detection register to sysfs
The glitch detection HW (TRC) save it status information into TRC status register. Make it available to user-space via read-only sysfs file. The TRC register is availab for PCH15 gen and newer, for older platforms reading the sysfs file will fail with EOPNOTSUPP.

x86/bugs: Add ITLB_MULTIHIT bug infrastructure
Some processors may incur a machine check error possibly resulting in an unrecoverable CPU lockup when an instruction fetch encounters a TLB multi-hit in the instruction TLB. This can occur when the page size is changed along with either the physical address or cache type. The relevant erratum can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=205195 There are other processors affected for which the erratum does not fully disclose the impact. This issue affects both bare-metal x86 page tables and EPT. It can be mitigated by either eliminating the use of large pages or by using careful TLB invalidations when changing the page size in the page tables. Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which are mitigated against this issue.
