Date: Mon, 10 Aug 2020 15:11:32 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Christian König <christian.koenig@....com>, Alex Deucher <alexander.deucher@....com>, Sasha Levin <sashal@...nel.org>, amd-gfx@...ts.freedesktop.org, dri-devel@...ts.freedesktop.org Subject: [PATCH AUTOSEL 5.4 24/45] drm/radeon: disable AGP by default From: Christian König <christian.koenig@....com> [ Upstream commit ba806f98f868ce107aa9c453fef751de9980e4af ] Always use the PCI GART instead. We just have to many cases where AGP still causes problems. This means a performance regression for some GPUs, but also a bug fix for some others.
