Message-Id: <20180920062924.6514-1-kraxel@redhat.com>
Date: Thu, 20 Sep 2018 08:29:23 +0200
From: Gerd Hoffmann <kraxel@...hat.com>

Subject: [PATCH] drm/virtio: pass virtio_gpu_object to virtio_gpu_cmd_transfer_to_host_{2d,3d}
Pass virtio_gpu_object down to virtio_gpu_cmd_transfer_to_host_2d and
virtio_gpu_cmd_transfer_to_host_3d functions, instead of passing just
the virtio resource handle.
This is needed to lookup the scatter list of the object, for dma sync.
