Subject: [PATCH] drm/amdgpu/pm: properly handle sclk for profiling modes on vangogh
Git-commit: 68e3871dcd6e547f6c47454492bc452356cb9eac
Patch-mainline: v5.16-rc1
References: stable-5.14.19
[ Upstream commit 68e3871dcd6e547f6c47454492bc452356cb9eac ]
When selecting between levels in the force performance levels interface
sclk (gfxclk) was not set correctly for all levels. Select the proper
sclk settings for all levels.
