Bug description:
[Impact]
It is for basic AMD HPT/STX/KRK function. Current PMF driver missing two
features:
1. For the thermal policy input, the AMD Fusion Sensor Hub could not pass the
data to PMF driver.
2. PMF driver could not parse the thermal policy binary which is stored in
the BIOS.
[Fix]
Need this series of patches which is included in linux-next
https://lore.kernel.org/platform-driver-x86/[email protected]/T/#t
2ab7713d6e94 platform/x86/amd/pmf: Add debug logs for pending requests and
custom BIOS inputs
62214d942d2b platform/x86/amd/pmf: Call enact function sooner to process
early pending requests
b21ec88340b7 platform/x86/amd/pmf: Preserve custom BIOS inputs for evaluating
the policies
04199ef48ac2 platform/x86/amd/pmf: Add custom BIOS input support for
AMD_CPU_ID_PS
4389d38080d7 platform/x86/amd/pmf: Add helper to verify BIOS input
notifications are enable/disable
37336ecb06a8 platform/x86/amd/pmf: Update ta_pmf_action structure member
ebc68a3451ce platform/x86/amd/pmf: Extend custom BIOS inputs for more policies
d82e3d2dd0ba platform/x86/amd/pmf: Fix the custom bios input handling
mechanism
f10ea2df9e4d platform/x86/amd/pmf: Add support for adjusting PMF PPT and PPT
APU thresholds
[Test]
PMF driver is loaded and function works properly on AMD platforms.
[Where problems could occur]
It's hard to evaluate the problems those patches may occur. Most of them are
withing amd/pmf, so it only impact the amd pmf functionailties.
