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.

drm/amd/pm: Remove arcturus min power limit

2024-11-21T20:56:06Z

As per power team, there is no need to impose a lower bound on arcturus power limit. Any unreasonable limit set will result in frequent throttling. Signed-off-by: Lijo Lazar Reviewed-by: Kenneth Feng Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amd/pm: remove redundant tools_size check

2024-11-20T14:38:12Z

The check for tools_size being non-zero is redundant as tools_size is explicitly set to a non-zero value (0x19000). Removing the if condition simplifies the code without altering functionality. Signed-off-by: Bhavin Sharma Signed-off-by: Alex Deucher
