Subject: [Intel-gfx] [PATCH v4 2/4] drm/i915/mtl: Add Wa_14015846243 to fix OA vs CS timestamp mismatch
Date: Mon, 12 Dec 2022 14:09:00 -0800 [thread overview]
Message-ID: <20221212220902.1819159-3-umesh.nerlige.ramappa@intel.com> (raw)
In-Reply-To: <20221212220902.1819159-1-umesh.nerlige.ramappa@intel.com>
Similar to ACM, OA timestamp that is part of the OA report is shifted
when compared to the CS timestamp. Add MTL to the WA.
