[PATCH 1/1] acpi-cpufreq: Honor _PSD table setting in CPU frequency control

2020-10-07 Thread Wei Huang
acpi-cpufreq has a old quirk that overrides the _PSD table supplied by BIOS on AMD CPUs. However the _PSD table of new AMD CPUs (Family 19h+) now accurately reports the P-state dependency of CPU cores. Hence this quirk needs to be fixed in order to support new CPUs' frequency control. Fixes: acd31
