Subject: [PATCH AUTOSEL 5.6 036/606] drm/amd/amdgpu: add raven1 part to the gfxoff quirk list
Date: Mon, 8 Jun 2020 19:02:41 -0400 [thread overview]
Message-ID: <20200608231211.3363633-36-sashal@kernel.org> (raw)
In-Reply-To: <20200608231211.3363633-1-sashal@kernel.org>
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.
