From 5fe0e3fc256e398fd1de01345ee3783801e2fef8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0282/1110] drm/amdgpu: send VCE IB tests directly to the ring
 again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We need the IB test for GPU resets as well and
the scheduler should be stoped then.
