| Subject: drm/amd/amdgpu: add raven1 part to the gfxoff quirk list |
| |
| From: Tom St Denis <tom.stdenis@amd.com> |
| |
| commit 975f543e7522e17b8a4bf34d7daeac44819aee5a upstream. |
| |
| On my raven1 system (rev c6) with VBIOS 113-RAVEN-114 GFXOFF is |
| not stable (resulting in large block tiling noise in some applications). |
| |
| Disabling GFXOFF via the quirk list fixes the problems for me. |
