Subject: [PATCH 0/2] amd-pstate: amd_pstate related fixes
Date: Mon, 22 May 2023 06:33:23 +0000 [thread overview]
Message-ID: <20230522063325.80193-1-wyes.karny@amd.com> (raw)
This 2 patch series has the following 2 fixes for amd_pstate:
- Currently, amd_pstate sets CPPC enable MSR for a single CPU. But ACPI
specification recommends driver to set CPPC enable register per-core.
Align amd_pstate driver with the spec.
- Remove some extra checks for active mode which are not required.
Wyes Karny (2):
cpufreq/amd-pstate: Write CPPC enable bit for each core
cpufreq/amd-pstate: Remove unnecessary active state checks
