Ah, Thanks for pointing that out Alex.
@Arvind, please refer to the patch
(https://patchwork.freedesktop.org/patch/504854/?series=109060&rev=4) in
previous series of SMU workload hints with UAPI (here:
https://patchwork.freedesktop.org/series/109060/)

KFD also changes the profile when queues are active. Please make sure

This reverts commit 5ce71f59bb9bd3d8a09b96afdbc92975cb6dc303.
Reason for revert: New amdgpu_smu* api is added to switch
on/off profile mode. These new api will allow to change the
GPU power profile based on a submitted job.
