Subject: [PATCH v3 0/7] GPU workload hints for better performance

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. 

v3:
- Addressed all review comment.
- Changed the function name from *_set() to *_get().
- Now clearing all the profile in work handler.
- Added *_clear_all function to clear all the power profile.

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: Set/Reset GPU workload profile
  drm/amdgpu: switch workload context to/from compute
  Revert "drm/amd/amdgpu: switch on/off vcn power profile mode"
