[PATCH AUTOSEL 5.7 28/60] drm/radeon: disable AGP by default

From: Sasha Levin <sashal@kernel.org>
Date: 2020-08-10 19:11:23
Also in: amd-gfx, dri-devel, lkml
Subsystem: drm drivers, radeon and amdgpu drm drivers, the rest · Maintainers: David Airlie, Simona Vetter, Alex Deucher, Christian König, Linus Torvalds

From: Christian König <christian.koenig@amd.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.
