In a core, the SBAF test engine is shared between sibling CPUs.
An SBAF test image contains multiple bundles. Each bundle is further
composed of subunits called programs. When a SBAF test (for a particular
core) is triggered by the user, each SBAF bundle from the loaded test
image is executed sequentially on all the threads on the core using
the stop_core_cpuslocked mechanism. Each bundle execution is initiated by
writing to MSR_ACTIVATE_SBAF.
SBAF test bundle execution may be aborted when an interrupt occurs or
if the CPU does not have enough power budget for the test. In these
cases the kernel restarts the test from the aborted bundle. SBAF
execution is not retried if the test fails or if the test makes no
forward progress after 5 retries.

Structural Based Functional Test at Field (SBAF) is a new type of
testing that provides comprehensive core test coverage complementing
existing IFS tests like Scan at Field (SAF) or ArrayBist.
SBAF device will appear as a new device instance (intel_ifs_2) under
/sys/devices/virtual/misc. The user interaction necessary to load the
test image and test a particular core is the same as the existing scan
test (intel_ifs_0).
During the loading stage, the driver will look for a file named
ff-mm-ss-<batch02x>.sbft in the /lib/firmware/intel/ifs_2 directory.
The hardware interaction needed for loading the image is similar to
SAF, with the only difference being the MSR addresses used. Reuse the
SAF image loading code, passing the SBAF-specific MSR addresses via
struct ifs_test_msrs in the driver device data.
Unlike SAF, the SBAF test image chunks are further divided into smaller
logical entities called bundles. Since the SBAF test is initiated per
bundle, cache the maximum number of bundles in the current image, which
is used for iterating through bundles during SBAF test execution.

IFS tests such as Scan at Field (SAF) or Structural Based Functional
Test at Field (SBAF), require the user to load a test image. The image
loading process is similar across these tests, with the only difference
being MSR addresses used. To reuse the code between these tests, remove
the hard coding of MSR addresses and allow the driver to pass the MSR
addresses per IFS test (via driver device data).
Add a new structure named "struct ifs_test_msrs" to specify the
test-specific MSR addresses. Each IFS test will provide this structure,
enabling them to reuse the common code.
This is a preliminary patch in preparation for the addition of SBAF
support.

If the Ambient Light Sensor (ALS) is disabled, the current code in the PMF
driver does not query for Human Presence Detection (HPD) data in

to evaluate policy conditions, leading to unexpected behavior in the policy
output actions.
To resolve this issue, modify the PMF driver to query HPD data
independently of ALS.
Since user_present is a boolean, modify the current code to return true if
the user is present and false if the user is away or if the sensor is not
detected, and report this status to the PMF TA firmware accordingly.
With this change, amd_pmf_get_sensor_info() now returns void instead of

Since commit e2ffcda162 ("ACPI: OSL: Allow Notify () handlers to run on
all CPUs") ACPI notify handlers like the intel-vbtn notify_handler() may
run on multiple CPU cores racing with themselves.
This race gets hit on Dell Venue 7140 tablets when undocking from
the keyboard, causing the handler to try and register priv->switches_dev
twice, as can be seen from the dev_info() message getting logged twice:
[ 83.861800] intel-vbtn INT33D6:00: Registering Intel Virtual Switches input-dev after receiving a switch event
[ 83.861858] input: Intel Virtual Switches as /devices/pci0000:00/0000:00:1f.0/PNP0C09:00/INT33D6:00/input/input17
[ 83.861865] intel-vbtn INT33D6:00: Registering Intel Virtual Switches input-dev after receiving a switch event
After which things go seriously wrong:
[ 83.861872] sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1f.0/PNP0C09:00/INT33D6:00/input/input17'
...
[ 83.861967] kobject: kobject_add_internal failed for input17 with -EEXIST, don't try to register things with the same name in the same directory.
[ 83.877338] BUG: kernel NULL pointer dereference, address: 0000000000000018
...
Protect intel-vbtn notify_handler() from racing with itself with a mutex
to fix this.

Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Here is the "big" set of char/misc and other driver subsystem changes
for 6.11-rc1. Nothing major in here, just loads of new drivers and
updates. Included in here are:
- IIO api updates and new drivers added
- wait_interruptable_timeout() api cleanups for some drivers
- MODULE_DESCRIPTION() additions for loads of drivers
- parport out-of-bounds fix
- interconnect driver updates and additions
- mhi driver updates and additions
- w1 driver fixes
- binder speedups and fixes
- eeprom driver updates
- coresight driver updates
- counter driver update
- new misc driver additions
- other minor api updates
All of these, EXCEPT for the final Kconfig build fix for 32bit systems,
have been in linux-next for a while with no reported issues. The
Kconfig fixup went in 29 hours ago, so might have missed the latest
linux-next, but was acked by everyone involved.

The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
samsung, imx, zynq and amlogic platoforms are farily small maintenance
changes, either addressing minor mistakes or enabling additional hardware.
The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and a
"shared memory bridge" driver.
The cznic "turris omnia" router based on Marvell Armada gets a platform
driver that talks to the board specific microcontroller.
The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some
code refactoring and new features.

Smatch complains that 'str' can be used without being initialized:
drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
error: uninitialized symbol 'str'.
In this loop, we iterate over all the set bits and print the name of the
bit. The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements. If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements. If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".
The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.
