In other words, with this option enabled, it should be possible to stream the content associated with the dmabuf to a remote client. Here is the flow of things from the Qemu side: - Call gl_scanout (to update the fd) and gl_draw_async just like in the local display case. - Additionally, create an update with the cmd set to QXL_CMD_DRAW to trigger the creation of a new drawable (associated with the fd) by the Spice server. - Wait (or block) until the Encoder is done encoding the content. - Unblock the pipeline once the async completion cookie is received. v2: - Use the existing gl_scanout and gl_draw_async APIs instead of adding new ones.
