AMDGPU SOCs supports dynamic workload based power profiles, which can provide fine-tuned performance for a particular type of workload. This patch series adds an interface to set/reset these power profiles based on the submitted job. The driver can dynamically switch the power profiles based on submitted job. This can optimize the power performance when the particular workload is on.
v2: - Splitting workload_profile_set and workload_profile_put into two separate patches. - Addressed review comment. - Added new suspend function. - Added patch to switches the GPU workload mode for KFD. Arvind Yadav (7): drm/amdgpu: Added init/fini functions for workload drm/amdgpu: Add new function to set GPU power profile drm/amdgpu: Add new function to put GPU power profile drm/amdgpu: Add suspend function to clear the GPU power profile. drm/amdgpu: Switch on/off GPU workload profile drm/amdgpu: switch workload context to/from compute Revert "drm/amd/amdgpu: switch on/off vcn power profile mode" drivers/gpu/drm/amd/amdgpu/Makefile | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 3 + drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c | 8 +- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 6 + drivers/gpu/drm/amd/amdgpu/amdgpu_job.c | 5 + drivers/gpu/drm/amd/amdgpu/amdgpu_vcn.c | 14 +- drivers/gpu/drm/amd/amdgpu/amdgpu_workload.c | 220 ++++++++++++++++++ drivers/gpu/drm/amd/include/amdgpu_workload.h | 61 +++++ 8 files changed, 303 insertions(+), 16 deletions(-) create mode 100644 drivers/gpu/drm/amd/amdgpu/amdgpu_workload.c create mode 100644 drivers/gpu/drm/amd/include/amdgpu_workload.h -- 2.34.1
