From 0d172de4060e4fa7de0ce4794d893a9f13ae37a6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5459/5725] drm/amdgpu:Use register UVD_SCRATCH9 for VCN
ring/ib test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Use register UVD_SCRATCH9 for VCN ring/ib test. Since those registers
can't be directly accessed under DPG(Dynamic Power Gate) mode.
