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. Mario Limonciello (14): 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: 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: Cache a pointer to policy in cpudata cpufreq/amd-pstate: Rework CPPC enabling cpufreq/amd-pstate: Stop caching EPP arch/x86/include/asm/msr-index.h | 18 +- arch/x86/kernel/acpi/cppc.c | 2 +- drivers/cpufreq/amd-pstate-trace.h | 13 +- drivers/cpufreq/amd-pstate-ut.c | 72 ++-- drivers/cpufreq/amd-pstate.c | 632 ++++++++++++++--------------- drivers/cpufreq/amd-pstate.h | 64 +-- 6 files changed, 398 insertions(+), 403 deletions(-)
