Subject: [PATCH v4 3/6] drm/virtio: batch plane updates (pageflip)
Date: Fri, 14 Feb 2020 13:55:32 +0100	[thread overview]
Message-ID: <20200214125535.26349-4-kraxel@redhat.com> (raw)
In-Reply-To: <20200214125535.26349-1-kraxel@redhat.com>

Move virtio_gpu_notify() to higher-level functions for
virtio_gpu_cmd_resource_flush(), virtio_gpu_cmd_set_scanout() and
virtio_gpu_cmd_transfer_to_host_{2d,3d}().

virtio_gpu_primary_plane_update() will notify only once for a series
of commands (restores plane update command batching).
