Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Since all the size checking has already happened, use input.pointer
(void *) so memcpy() doesn't get confused about how much is being
written.
Avoids this false-positive warning when run-time memcpy() strict
bounds checking is enabled:
memcpy: detected field-spanning write (size 4096) of single field (size 36)

Alder Lake has 14 status registers that are memory mapped. These
registers show the status of the low power mode requirements. The
registers are latched on every C10 entry or exit and on every s0ix.y
entry/exit. Accessing these registers is useful for debugging any low
power related activities.
Thus, add debugfs entry to access low power mode status registers.

Add initial support for platform_profile where the support is
based on availability of ASUS_THROTTLE_THERMAL_POLICY.
Because throttle_thermal_policy is used by platform_profile and is
writeable separately to platform_profile any userspace changes to
throttle_thermal_policy need to notify platform_profile.
In future throttle_thermal_policy sysfs should be removed so that
only one method controls the laptop power profile.

Dynamic BIOS SAR driver exposing dynamic SAR information from BIOS
The Dynamic SAR (Specific Absorption Rate) driver uses ACPI DSM
(Device Specific Method) to communicate with BIOS and retrieve
dynamic SAR information and change notifications. The driver uses
sysfs to expose this data to userspace via read and notify.
Sysfs interface is documented in detail under:

Althrough the Fn lock (Fn + Esc) works on Legion 5 (R7000P), its LED

Substate priority levels are encoded in 4 bits in the LPM_PRI register.
This value was used as an index to an array whose element size was less
than 16, leading to the possibility of overflow should we read a larger
than expected priority. In addition to the overflow, bad values could lead
to incorrect state reporting. So rework the priority code to prevent the
overflow and perform some validation of the register. Use the priority
register values if they give an ordering of unique numbers between 0 and
the maximum number of states. Otherwise, use a default ordering instead.

The Acer Predator Helios series (usually denoted by PHxxx-yy) features
a particular key above the keyboard named "TURBO".
The turbo key does 3 things:
1. Set all fan's speeds to TURBO mode
2. Overclocks the CPU and GPU in the safe range
3. Turn on an LED just below the turbo button
All the above actions are operating using WMI function calls,
and there is no custom OC level for turbo. It acts as a flag
for enabling turbo mode instead of telling processors to use
a specific multiply of power (e.g. 1.3x of power).
I've run some benchmark tests and it worked fine:
GpuTest 0.7.0
http://www.geeks3d.com
Module: FurMark
Normal mode Score: 7289 points (FPS: 121)
Turbo mode Score: 7675 points (FPS: 127)
Settings:
- 1920x1080 fullscreen
- antialiasing: Off
- duration: 60000 ms
Renderer:
- GeForce RTX 2060/PCIe/SSE2
- OpenGL: 4.6.0 NVIDIA 460.32.03
This feature is presented by Acer officially and should not harm
hardware in any case.
A challenging part of implementing this feature is that calling
overclock function requires knowing the exact count of fans
for CPU and GPU of each model, which to the best of my
knowledge is not available in the kernel.
So after checking the official PredatorSense application methods, it
turned out they have provided the software the list of fans in each model.
I have access to the mentioned list, and all similar PH-iii-jj can be
added easily by matching "DMI_PRODUCT_NAME".
Creating a specific file for the Acer gaming features is not possible
because the current in use WMI event GUID is required for the turbo button
and it's not possible to register multiple listeners on a single WMI event.
