Wyes Karny
May 22, 2023, 6:33 a.m. UTC
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 drivers/cpufreq/amd-pstate.c | 64 ++++++++++++++++-------------------- 1 file changed, 28 insertions(+), 36 deletions(-)
