Subject: [Intel-gfx] [PATCH v10 2/8] drm/i915: Add support for async flips in I915
Date: Mon, 21 Sep 2020 16:32:04 +0530	[thread overview]
Message-ID: <20200921110210.21182-3-karthik.b.s@intel.com> (raw)
In-Reply-To: <20200921110210.21182-1-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)

v7: -Move async address update enable to skl_plane_ctl_crtc() (Ville)

v8: -Rebased.

v9: -Rebased.
