The following changes since commit d082ecbc71e9e0bf49883ee4afd435a77a5101b6: Linux 6.14-rc4 (2025-02-23 12:32:57 -0800) are available in the Git repository at: ssh://git@gitolite.kernel.org/pub/scm/linux/kernel/git/superm1/linux.git tags/amd-pstate-v6.15-2025-03-06 for you to fetch changes up to efb758c8c803217e58248f03db372c5e23827dae: cpufreq/amd-pstate: Drop actions in amd_pstate_epp_cpu_offline() (2025-03-06 13:01:26 -0600) ---------------------------------------------------------------- amd-pstate content for 6.15 (3/6/25) A lot of code optimization to avoid cases where call paths will end up calling the same writes multiple times and needlessly caching variables. To accomplish this some of the writes are now made into an atomically written "perf" variable. Locking has been overhauled to ensure it only applies to the necessary functions. Tracing has been adjusted to ensure trace events only are used right before writing out to the hardware. NOTE: This is a redo of amd-pstate-v6.15-2025-03-03 with a fixed Fixes tag. ---------------------------------------------------------------- Dhananjay Ugwekar (10): cpufreq/amd-pstate: Modify the min_perf calculation in adjust_perf callback cpufreq/amd-pstate: Remove the redundant des_perf clamping in adjust_perf cpufreq/amd-pstate: Pass min/max_limit_perf as min/max_perf to amd_pstate_update cpufreq/amd-pstate: Convert all perf values to u8 cpufreq/amd-pstate: Modularize perf<->freq conversion cpufreq/amd-pstate: Remove the unnecessary cpufreq_update_policy call cpufreq/amd-pstate: Add missing NULL ptr check in amd_pstate_update cpufreq/amd-pstate: Use scope based cleanup for cpufreq_policy refs cpufreq/amd-pstate: Remove the unncecessary driver_lock in amd_pstate_update_limits cpufreq/amd-pstate: Fix the clamping of perf values 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 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 actions in 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 | 57 +++++++++++---------- drivers/cpufreq/amd-pstate-ut.c | 211 ++++++++++++++++++++++++++++++++------------------------------------------- drivers/cpufreq/amd-pstate.c | 666 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-------------------------------------------------------------------------------------------------------------------------------------- drivers/cpufreq/amd-pstate.h | 65 +++++++++++++----------- include/linux/cpufreq.h | 3 ++ 7 files changed, 461 insertions(+), 565 deletions(-)
