3573fee87f platform/x86: lg-laptop: Add operation region support
The LEGX0820 ACPI device is expected to provide a custom operation
region:

	OperationRegion (XIN1, 0x8F, Zero, 0x04B0)
        Field (XIN1, AnyAcc, Lock, Preserve)
        {
            DMSG,   8,
            HDAP,   8,
            Offset (0x03),
            AFNM,   8,
            Offset (0x10),
            P80B,   8,
            P81B,   8,
            P82B,   8,
            P83B,   8,
            P84B,   8,
            P85B,   8,
            P86B,   8,
            P87B,   8,
            Offset (0x20),
            DTTM,   8,
            TMP1,   8,
            LTP1,   8,
            HTP1,   8,
            TMP2,   8,
            LTP2,   8,
            HTP2,   8,
            Offset (0x3E8),
            PMSG,   1600
        }

The PMSG field is used by AML code to log debug messages when DMSG is
true. Since those debug messages are already logged using the standard
ACPI Debug object, we set DMSG unconditionally to 0x00 and ignore any
writes to PMSG.

The TMPx, LTPx, HTPx and AFNM fields are used to inform the driver when
the temperature/(presumably) trip points/fan mode changes. This only
happens when the DTTM flag is set.

Unfortunately we have to implement support for this operation region
because the AML codes uses code constructs like this one:

	If (((\_SB.XINI.PLAV != Zero) && (\_SB.XINI.DTTM != Zero)))

The PLAV field gets set to 1 when the driver registers its address space
handler, so by default XIN1 should not be accessed.

However ACPI does not use short-circuit evaluation when evaluating
logical conditions. This causes the DTTM field to be accessed even
when PLAV is 0, which results in an ACPI error.
Since this check happens inside various thermal-related ACPI control
methods, various thermal zone become unusable since any attempt to
read their temperature results in an ACPI error.

Fix this by providing support for this operation region. I suspect
that the problem does not happen under Windows (which seemingly does
not use short-circuit evaluation either) because the necessary driver
comes preinstalled with the machine.

3c4d06bd6e platform/x86/intel/ifs: Add SBAF test support
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.

0a3e4e94d1 platform/x86/intel/ifs: Add SBAF test image loading support
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.

7e597d496d platform/x86/intel/ifs: Refactor MSR usage in IFS test code
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.

and module_exit() respectively, there is no contention while calling
misc_register()/misc_deregister or isst_if_cpu_info_init()/
isst_if_cpu_info_exit().

Hence remove mutex and reference counting.

platform/x86: ideapad-laptop: add a mutex to synchronize VPC commands
Calling VPC commands consists of several VPCW and VPCR ACPI calls.
These calls and their results can get mixed up if they are called
simultaneously from different threads, like acpi notify handler,
sysfs, debugfs, notification chain.

The commit e2ffcda162 ("ACPI: OSL: Allow Notify () handlers to run on
all CPUs") made the race issues much worse than before it but some
races were possible even before that commit.

Add a mutex to synchronize VPC commands.

platform/x86: ideapad-laptop: move ymc_trigger_ec from lenovo-ymc
Some models need to trigger the EC after each YMC event for the yoga
mode control to work properly. EC triggering consist of a VPC call from
the lenovo-ymc module. Except for this, all VPC calls are in the
ideapad-laptop module.

Since ideapad-laptop has a notification chain, a new YMC_EVENT action
can be added and triggered from the lenovo-ymc module. Then the
ideapad-laptop can trigger the EC.

If the triggering is in the ideapad-laptop module, then the ec_trigger
module parameter should be there as well.

Move the ymc_trigger_ec functionality and the ec_trigger module
parameter to the ideapad-laptop module.

platform/x86/amd/pmf: Fix to Update HPD Data When ALS is Disabled
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
amd_pmf_get_sensor_info(). As a result, stale HPD data is used by PMF-TA
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
int.

017fa3e891 minmax: simplify and clarify min_t()/max_t() implementation
This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.

That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

4477b39c32 minmax: add a few more MIN_T/MAX_T users
Commit 3a7e02c040 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.

The complexity of those macros stems from two issues:

 (a) trying to use them in situations that require a C constant
     expression (in static initializers and for array sizes)

 (b) the type sanity checking

and MIN_T/MAX_T avoids both of these issues.

Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.

But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.

However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.

This does exactly that.

Which in turn will then allow for much simpler implementations of
min_t()/max_t().  All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.

We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:

  $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
  clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]

This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.

'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.

All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

 - Refactor to a common struct for DRAM and general media CXL events
 - Add abstract distance calculation support for CXL
 - Add CXL maturity map documentation to detail current state of CXL enabling
 - Add warning on mixed CXL VH and RCH/RCD hierachy to inform unsupported config
 - Replace ENXIO with EBUSY for inject poison limit reached via debugfs
 - Replace ENXIO with EBUSY for inject poison cxl-test support
 - XOR math fixup for DPA to SPA translation. Current math works for MODULO arithmetic
   where HPA==SPA, however not for XOR decode.
 - Move pci config read in cxl_dvsec_rr_decode() to avoid unnecessary acess
 
 Fixes:
 - Add a fix to address race condition in CXL memory hotplug notifier
 - Add missing MODULE_DESCRIPTION() for CXL modules
 - Fix incorrect vendor debug UUID define

Merge tag 'cxl-for-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL updates from Dave Jiang:
 "Core:

   - A CXL maturity map has been added to the documentation to detail
     the current state of CXL enabling.

     It provides the status of the current state of various CXL features
     to inform current and future contributors of where things are and
     which areas need contribution.

   - A notifier handler has been added in order for a newly created CXL
     memory region to trigger the abstract distance metrics calculation.

     This should bring parity for CXL memory to the same level vs
     hotplugged DRAM for NUMA abstract distance calculation. The
     abstract distance reflects relative performance used for memory
     tiering handling.

   - An addition for XOR math has been added to address the CXL DPA to
     SPA translation.

     CXL address translation did not support address interleave math
     with XOR prior to this change.

  Fixes:

   - Fix to address race condition in the CXL memory hotplug notifier

   - Add missing MODULE_DESCRIPTION() for CXL modules

   - Fix incorrect vendor debug UUID define

  Misc:

   - A warning has been added to inform users of an unsupported
     configuration when mixing CXL VH and RCH/RCD hierarchies

   - The ENXIO error code has been replaced with EBUSY for inject poison
     limit reached via debugfs and cxl-test support

   - Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
     unnecessary PCI config reads

   - A refactor to a common struct for DRAM and general media CXL
     events"
