Subject: [PATCH 0/3] 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.

Arvind Yadav (3):
  drm/amdgpu: Add new api to switch on/off power profile mode
  drm/amdgpu: Switch on/off GPU workload profile
  Revert "drm/amd/amdgpu: switch on/off vcn power profile mode"
