Subject: [PATCH 1/2] drm/amdgpu/gmc9: print client id string for gfxhub
Date: Tue, 1 Sep 2020 17:51:24 -0400 [thread overview]
Message-ID: <20200901215125.1402033-1-alexander.deucher@amd.com> (raw)
Print the name of the client rather than the number. This
makes it easier to debug what block is causing the fault.
