This patch improves the platform profile handling for laptops using the
Acer Predator interface by making the following changes -
1) Using WMI calls to fetch the current platform profile instead of
directly accessing it from the EC.
2) Using an ACPI bitmap to dynamically set platform_profile_choices.
3) Simplifying the cycling of platform profiles by making use of
platform_profile_cycle()
v1->v2:
[1]
- Fixed enum member alignment and reordered them
[2]
- Made use of test_bit to check bitmap values
- Replaced magic numbers with proper variables

For consistency, I > think it should be refactored to use WMID_gaming_set_misc_setting() > instead of WMID_gaming_set_u64(). Yeah I agree. Actually, now that we have this function, this particular case in WMID_gaming_set_u64() is redundant, so can I remove it?

Please do the conversion of the OC settings in a separate patch so that it is easier to review. Keep in mind that you emulate the behavior of WMID_gaming_set_u64() and check if the interface has ACER_CAP_TURBO_OC before calling WMID_gaming_set_misc_settings() to change the OC settings.

I thought that the purpose of last_non_turbo_profile was for acer_thermal_profile_change() to store the profile just before toggling turbo so that the system can return to it later on (as mentioned in the comments). I don't see a valid use case for this variable outside of that specific context, which is why I decided to remove its update during manual profile changes.

Without this, when users change profiles and set turbo mode using applications or scripts (like predator sense GUI on windows) then use the mode button to return from turbo mode, it returns to default or the last value by the button, not the actual last profile.
