Subject: [Intel-gfx] [PATCH v6 2/7] drm/i915: Add support for async flips in I915
Date: Fri, 7 Aug 2020 15:05:46 +0530 [thread overview]
Message-ID: <20200807093551.10673-3-karthik.b.s@intel.com> (raw)
In-Reply-To: <20200807093551.10673-1-karthik.b.s@intel.com>
Set the Async Address Update Enable bit in plane ctl
when async flip is requested.
v2: -Move the Async flip enablement to individual patch (Paulo)
v3: -Rebased.
v4: -Add separate plane hook for async flip case (Ville)
v5: -Rebased.
v6: -Move the plane hook to separate patch. (Paulo)
-Remove the early return in skl_plane_ctl. (Paulo)
