From: Mario Limonciello <mario.limonciello@amd.com> 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. v3->v4: * Cleanups from v3 feedback * One new patch to drop unnecessary extra call for setting perf on cpu offline Mario Limonciello (19): cpufreq/amd-pstate: Invalidate cppc_req_cached during suspend 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: Run on all of the correct CPUs 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 cpufreq/amd-pstate: Stop caching EPP cpufreq/amd-pstate: Drop amd_pstate_epp_cpu_offline() arch/x86/include/asm/msr-index.h | 20 +- arch/x86/kernel/acpi/cppc.c | 4 +- drivers/cpufreq/amd-pstate-trace.h | 13 +- drivers/cpufreq/amd-pstate-ut.c | 209 +++++------ drivers/cpufreq/amd-pstate.c | 580 +++++++++++++---------------- drivers/cpufreq/amd-pstate.h | 61 +-- 6 files changed, 410 insertions(+), 477 deletions(-)
