[PATCH v2 00/17] amd-pstate cleanups
From: Mario Limonciello
Date: Fri Feb 14 2025 - 19:54:30 EST
From: Mario Limonciello <mario.limonciello@xxxxxxx>
This series overhauls locking and drops many unnecessarily cached
variables.
Debugging messages are also dropped in favor of more ftracing.
This series is based off superm1/linux.git bleeding-edge branch.
Mario Limonciello (17):
cpufreq/amd-pstate: Show a warning when a CPU fails to setup
cpufreq/amd-pstate: Drop min and max cached frequencies
cpufreq/amd-pstate: Move perf values into a union
cpufreq/amd-pstate: Overhaul locking
cpufreq/amd-pstate: Drop `cppc_cap1_cached`
cpufreq/amd-pstate-ut: Use _free macro to free put policy
cpufreq/amd-pstate-ut: Allow lowest nonlinear and lowest to be the
same
cpufreq/amd-pstate-ut: Drop SUCCESS and FAIL enums
cpufreq/amd-pstate-ut: Continue on missing policies
cpufreq/amd-pstate-ut: Adjust variable scope for
amd_pstate_ut_check_freq()
cpufreq/amd-pstate: Replace all AMD_CPPC_* macros with masks
cpufreq/amd-pstate: Cache CPPC request in shared mem case too
cpufreq/amd-pstate: Move all EPP tracing into *_update_perf and
*_set_epp functions
cpufreq/amd-pstate: Update cppc_req_cached for shared mem EPP writes
cpufreq/amd-pstate: Drop debug statements for policy setting
cpufreq/amd-pstate: Rework CPPC enabling
