b2b6fa6f5c platform/x86/amd/pmf: Fix a suspend hang on Framework 13
The buffer is cleared in the suspend handler but used in
the delayed work for amd_pmf_get_metrics().

dbcbfd662a platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI names
On some devices the ACPI name of the touchscreen is e.g. either
MSSL1680:00 or MSSL1680:01 depending on the BIOS version.

This happens for example on the "Chuwi Hi8 Air" tablet where the initial
commit's ts_data uses "MSSL1680:00" but the tablets from the github issue
and linux-hardware.org probe linked below both use "MSSL1680:01".

Replace the strcmp() match on ts_data->acpi_name with a strstarts()
check to allow using a partial match on just the ACPI HID of "MSSL1680"
and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly
to fix the touchscreen not working on models where it is "MSSL1680:01".

Note this drops the length check for I2C_NAME_SIZE. This never was
necessary since the ACPI names used are never more then 11 chars and
I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long
before reaching I2C_NAME_SIZE.

Since commit 7a36b901a6 ("ACPI: OSL: Use a threaded interrupt handler
for SCI") the ACPI OSL code passes IRQF_ONESHOT when requesting the SCI.

Since the INT0002 GPIO is typically shared with the ACPI SCI the INT0002
driver must pass the same flags.

This fixes the INT0002 driver failing to probe due to following error +
as well as removing the backtrace that follows this error:

5b559e8ab0 platform/x86: wmi: Make input buffer mandatory when evaluating methods
The ACPI-WMI specification declares in the section "ACPI Control Method
Naming Conventions and Functionality for Windows 2000 Instrumentation"
that a WMxx control method takes 3 arguments: instance, method id and
argument buffer. This is also the case even when the underlying WMI
method does not have any input arguments.

So if a WMI driver evaluates a WMI method without passing an input
buffer, ACPICA will log a warning complaining that the third argument
is missing.

Prevent this by checking that a input buffer was passed, and return
an error if this was not the case.

Tested on a Asus PRIME B650-Plus.

3a057bf30e platform/x86: hp-wmi: Add thermal profile support for 8BAD boards
Add 8BAD to the list of boards which have thermal profile selection
available. This allows the CPU to draw more power than the default TDP
barrier defined by the 'balanced' thermal profile (around 50W), hence
allowing it to perform better without being throttled by the embedded
controller (around 130W).

We first need to set the HP_OMEN_EC_THERMAL_PROFILE_TIMER_OFFSET to zero.
This prevents the timer countdown from reaching zero, making the embedded
controller "force-switch" the system's thermal profile back to 'balanced'
automatically.

We also need to put a number of specific flags in
HP_OMEN_EC_THERMAL_PROFILE_FLAGS_OFFSET when we're switching to another
thermal profile:

   - for 'performance', we need to set both HP_OMEN_EC_FLAGS_TURBO and
     HP_OMEN_EC_FLAGS_NOTIMER;

   - for 'balanced' and 'powersave', we clear out the register to notify
     the system that we want to lower the TDP barrier as soon as possible.

The third flag defined in the hp_thermal_profile_omen_flags enum,
HP_OMEN_EC_FLAGS_JUSTSET, is present for completeness.

To prevent potential behaviour breakage with other Omen models, a
separate omen_timed_thermal_profile_boards array has been added to list
which boards expose this behaviour.

Performance benchmarking was done with the help of silver.urih.com and
Google Chrome 120.0.6099.129, on Gnome 45.2, with the 'performance'
thermal profile set:

|                  | Performance |     Stress |   TDP |
|------------------|-------------|------------|-------|
|    with my patch |      P84549 |    S0.1891 |  131W |
| without my patch |      P44084 |    S0.1359 |   47W |

The TDP measurements were done with the help of the s-tui utility,
during the load.

There is still work to be done:

   - tune the CPU and GPU fans to better cool down and enhance
     performance at the right time; right now, it seems that the fans are
     not properly reacting to thermal/performance events, which in turn
     either causes thermal throttling OR makes the fans spin way too long,
     even though the temperatures have lowered down

   - expose the CPU and GPU fan curves to user-land so that they can be
     controlled just like what the Omen Gaming Hub utility proposes to
     its users;

24b10e5f8e platform/x86: hp-wmi: Tidy up module source code
This commit performs four things:

   - fix up the GUID string inconsistency (lower case 'e') from the

   - separate GUID macros from the embedded controller offset macros

   - rename the description of the module to better represent what it
     actually achieves as a whole

   - add a space right before the '*' pointer qualifier to match the
     other array declarations

This also prepares the terrain for integrating support work for boards
identified as '8BAD', which corresponds to HP's Omen 17 ck2xxx models.

The activation for Scan at Field (SAF) includes a parameter to make
microcode wait for both threads to join. It's preferable to perform an
entry rendezvous before the activation to ensure that they start the
`wrmsr` close enough to each other. In some cases it has been observed
that one of the threads might be just a bit late to arrive. An entry
rendezvous reduces the likelihood of these cases occurring.

Add an entry rendezvous to ensure the activation on both threads happen

ea15f34d5f platform/x86/intel/ifs: Replace the exit rendezvous with an entry rendezvous for ARRAY_BIST
ARRAY_BIST requires the test to be invoked only from one of the HT
siblings of a core.  If the other sibling was in mwait(), that didn't
permit the test to complete and resulted in several retries before the
test could finish.

The exit rendezvous was introduced to keep the HT sibling busy until
the primary CPU completed the test to avoid those retries. What is
actually needed is to ensure that both the threads rendezvous *before*
the wrmsr to trigger the test to give good chance to complete the test.

The `stop_machine()` function returns only after all the CPUs complete
running the function, and provides an exit rendezvous implicitly.

In kernel/stop_machine.c::multi_cpu_stop(), every CPU in the mask
needs to complete reaching MULTI_STOP_RUN. When all CPUs complete, the
state machine moves to next state, i.e MULTI_STOP_EXIT. Thus the
underlying API stop_core_cpuslocked() already provides an exit
rendezvous.

Add the rendezvous earlier in order to ensure the wrmsr is triggered
after all CPUs reach the do_array_test(). Remove the exit rendezvous
since stop_core_cpuslocked() already guarantees that.

fed99212ac treewide, serdev: change receive_buf() return type to size_t
receive_buf() is called from ttyport_receive_buf() that expects values
">= 0" from serdev_controller_receive_buf(), change its return type from
ssize_t to size_t.

The need for this clean-up was noticed while fixing a warning, see
commit 94d0539425 ("Bluetooth: btnxpuart: fix recv_buf() return value").
Changing the callback prototype to return an unsigned seems the best way
to document the API and ensure that is properly used.

GNSS drivers implementation of serdev receive_buf() callback return
directly the return value of gnss_insert_raw(). gnss_insert_raw()
returns a signed int, however this is not an issue since the value
returned is always positive, because of the kfifo_in() implementation.
gnss_insert_raw() could be changed to return also an unsigned, however
this is not implemented here as request by the GNSS maintainer Johan
Hovold.
