    Subject[PATCH 5.7 090/393] drm/radeon: disable AGP by default
    Date
    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.
