From 975f543e7522e17b8a4bf34d7daeac44819aee5a Mon Sep 17 00:00:00 2001 From: Tom St Denis Date: Thu, 7 May 2020 08:35:40 -0400 Subject: [PATCH] drm/amd/amdgpu: add raven1 part to the gfxoff quirk list 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.
