Subject: [Intel-gfx] [PATCH 0/2] drm/i915/fbc: Avoid GLK+ FBC corruption
Date: Thu, 22 Apr 2021 21:29:55 +0300 [thread overview]
Message-ID: <20210422182957.10022-1-ville.syrjala@linux.intel.com> (raw)
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Remove redundant manual FBC nukes to avoid the GLK+ FBC
nuke+disable+plane update fail and causing the top of the screen
to become corrupted. A 100% workaround likely needs yet another
vblank wait, but that's not entirely trivial to do without
hurting interactivity, so for now at least try to avoid the
issue for purely page flipped workloads.
