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:

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.

In Windows the ASUS Armory Crate program can enable or disable the
dGPU via a WMI call. This functions much the same as various Linux
methods in software where the dGPU is removed from the device tree.
However the WMI call saves the state of dGPU (enabled or not) and
this then changes the dGPU visibility in Linux with no way for
Linux users to re-enable it. We expose the WMI method so users can
see and change the dGPU ACPI state.

dell-smbios is depended on by dell-laptop and that has this same table +
some extra entries for chassis-type 30, 31 and 32.
Since dell-laptop will already auto-load based on the DMI table in there
(which also is more complete) and since dell-laptop will then bring in
the dell-smbios module, the only scenario I can think of where this DMI
table inside dell-smbios-smm.c is useful is if users have the dell-laptop
module disabled and they want to use the sysfs interface offered by
dell-smbios-smm.c. But that is such a corner case, even requiring a custom
kernel build, that it does not weigh up against having this duplicate
table, which as the current state already shows can only grow stale.

Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers
to allow the OS to determine the angle between the display and the base of
the device.
On Windows these are read by a special HingeAngleService process which
calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is
in tablet- or laptop-mode. The firmware may use this to disable the kbd and
touchpad to avoid spurious input in tablet-mode as well as to report
SW_TABLET_MODE info to the OS.
Since Linux does not call these undocumented methods, the SW_TABLET_MODE
info reported by various pdx86 drivers is incorrect on these devices.
Before this commit the intel-hid and thinkpad_acpi code already had 2
hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid
reporting broken info.
And now we also have a bug-report about the same problem in the intel-vbtn
code. Since there are at least 3 different ACPI hardware-ids in play, add
a new dual_accel_detect() helper which checks for all 3, rather then
adding different hardware-ids to the drivers as bug-reports trickle in.
Having shared code which checks all known hardware-ids is esp. important
for the intel-hid and intel-vbtn drivers as these are generic drivers
which are used on a lot of devices.
The BOSC0200 hardware-id requires special handling, because often it is
used for a single-accelerometer setup. Only in a few cases it refers to
a dual-accel setup, in which case there will be 2 I2cSerialBus resources
in the device's resource-list, so the helper checks for this.
