Subject: [Intel-gfx] [PATCH 7/7] drm/i915: Enable GGTT updates with binder in MTL
Date: Mon, 18 Sep 2023 19:02:57 +0200	[thread overview]
Message-ID: <20230918170257.8586-8-nirmoy.das@intel.com> (raw)
In-Reply-To: <20230918170257.8586-1-nirmoy.das@intel.com>

MTL can hang because of a HW bug while parallel reading/writing
from/to LMEM/GTTMMADR BAR so try to reduce GGTT update
related pci transactions with blitter command as recommended
for Wa_13010847436 and Wa_14019519902.
