drm/amdgpu/smu13: update powersave optimizations

2025-01-10T18:30:58Z

Only apply when compute profile is selected. This is the only supported configuration. Selecting other profiles can lead to performane degradations.

drm/amd/pm: Set SMU v13.0.7 default workload type

2024-12-05T19:31:54Z

Set the default workload type to bootup type on smu v13.0.7. This is because of the constraint on smu v13.0.7. Gfx activity has an even higher set point on 3D fullscreen mode than the one on bootup mode. This causes the 3D fullscreen mode's performance is worse than the bootup mode's performance for the lightweighted/medium workload. For the high workload, the performance is the same between 3D fullscreen mode and bootup mode. v2: set the default workload in ASIC specific file Signed-off-by: Kenneth Feng Reviewed-by: Yang Wang Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org # 6.11.x

drm/amd/pm: Initialize power profile mode

2024-12-05T19:31:14Z

Refactor such that individual SMU IP versions can choose the startup power profile mode. If no preference, then use the generic default power profile selection logic. Signed-off-by: Lijo Lazar Reviewed-by: Yang Wang Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org # 6.11.x

drm/amd/pm: fix and simplify workload handling

2024-12-02T23:36:15Z

smu->workload_mask is IP specific and should not be messed with in the common code. The mask bits vary across SMU versions. Move all handling of smu->workload_mask in to the backends and simplify the code. Store the user's preference in smu->power_profile_mode which will be reflected in sysfs. For internal driver profile switches for KFD or VCN, just update the workload mask so that the user's preference is retained. Remove all of the extra now unused workload related elements in the smu structure. v2: use refcounts for workload profiles v3: rework based on feedback from Lijo v4: fix the refcount on failure, drop backend mask v5: rework custom handling v6: handle failure cleanup with custom profile v7: Update documentation Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher Cc: Kenneth Feng Cc: Lijo Lazar Cc: stable@vger.kernel.org # 6.11.x

Revert "drm/amd/pm: correct the workload setting"

2024-12-02T23:35:57Z

This reverts commit 74e1006430a5377228e49310f6d915628609929e. This causes a regression in the workload selection. A more extensive fix is being worked on. For now, revert. This came back after a merge in 6.13-rc1, so revert again.
