platform/x86/amd: pmf: Add quirk for ROG Zephyrus G14

2024-04-16T12:17:32Z

ROG Zephyrus G14 advertises support for SPS notifications to the BIOS but doesn't actually use them. Instead the asus-nb-wmi driver utilizes such events. Add a quirk to prevent the system from registering for ACPI platform profile when this system is found to avoid conflicts.

2024-04-16T12:17:27Z

ASUS ROG Zephyrus G14 doesn't have _CRS in AMDI0102 device and so there are no resources to walk. This is expected behavior because it doesn't support Smart PC. Decrease error message to debug.

platform/x86/amd/pmf: Add support to get sps default APTS index values

2024-03-12T10:48:32Z

During the driver probe, the default cache values for the static slider would be obtained by evaluating the APTS method. Add support to use these values as the thermal settings to be updated on the system based on the changing platform-profiles.

platform/x86/amd/pmf: Add support to notify sbios heart beat event

2024-03-12T10:48:28Z

Add support for newer revision of the heart beat notify events. This event is used to notify to the OEM BIOS on driver load/unload/suspend/resume scenarios. If OEM BIOS does not receive the heart beat event from PMF driver, OEM BIOS shall conclude that PMF driver is no more active and BIOS will update to the legacy system power thermals.
