[PATCH v2 0/8] platform/x86: asus-wmi:

From: Luke D. Jones
Date: Fri Jun 30 2023 - 01:36:09 EST


This patch series adds or exposes more features that are available in the ROG
laptop series.

- expose dGPU and CPU tunables for ROG
- These are things like GPU boost, CPU Pl1 and PL2, package power limits
- support setting mini-LED mode
- Some newer laptops have a screen that can toggle between regular style
backlight and using mini-LED backlight
- add WMI method to show if egpu connected
- This WMI method can be monitored/queried to see if it is possible to begin
the change-over to eGPU
- support middle fan custom curves
- Some newer laptops have a center/middle fan which blows across the CPU and GPU
- add support for showing middle fan RPM
- add support for showing charger mode (AC, USB-C, both plugged)
- add additional checks to GPU switching code
- These try to prevent a sceanrio such as the user disabling the dGPU while it
is driving the internal panel via MUX, resulting in no output at all.
There are no checks in the ACPI code for this, but on some newer models ASUS
did finally add a switch in the BIOS menu. It is best to try and prevent this
at the kernel level rather than userland level.

All patches pass ./scripts/checkpatch.pl

Changelog:
- v2-0008-platform-x86-asus-wmi-expose-dGPU-and-CPU-tunable.patch
- Rename the WMI defs to match what ASUS supplied as names
- Remove EDC and TDC exposure (unsafe)
- Slight change to formatting
- Add better notes to documentation
