Subject: [PATCH] drm/i915/mtl: Update workaround 14018778641
Date: Thu, 22 Feb 2024 19:27:15 +0530 [thread overview]
Message-ID: <20240222135715.1552235-1-tejas.upadhyay@intel.com> (raw)
Applying WA 14018778641 only on Compute engine has impact on
some apps like chrome. Updating this WA to apply on Render
engine as well as it is helping with performance on Chrome.
Note: There is no concern from media team thus not applying
WA on media engines. We will revisit if any issues reported
from media team.
Fixes: 668f37e1ee11 ("drm/i915/mtl: Update workaround 14018778641")
