Subject: [PATCH 3/4] drm: virtio-gpu: transfer dumb buffers to host on plane update
Date: Wed, 13 Jan 2016 15:52:09 -0600	[thread overview]
Message-ID: <1452721930-14714-4-git-send-email-robh@kernel.org> (raw)
In-Reply-To: <1452721930-14714-1-git-send-email-robh@kernel.org>

For dumb buffers, we need to transfer them to the host when updating a
plane.
