    Subject[PATCH 5.6 152/194] drm/amd/amdgpu: add raven1 part to the gfxoff quirk list
    Date
    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.
