    Subject[PATCH 5.17 200/219] drm/amdgpu: Enable gfxoff quirk on MacBook Pro
    Date
    From: Tomasz Moń <desowin@gmail.com>

    commit 4593c1b6d159f1e5c35c07a7f125e79e5a864302 upstream.

    Enabling gfxoff quirk results in perfectly usable graphical user
    interface on MacBook Pro (15-inch, 2019) with Radeon Pro Vega 20 4 GB.

    Without the quirk, X server is completely unusable as every few seconds
    there is gpu reset due to ring gfx timeout.
