Add new virtio-gpu devices with a "vhost-user" property. The associated vhost-user backend is used to handle the virtio rings and provide rendering results thanks to the vhost-user-gpu protocol. Example usage: -object vhost-user-backend,id=vug,cmd="./vhost-user-gpu" -device vhost-user-vga,vhost-user=vug Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-id: 20190524130946.31736-10-marcandre.lureau@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
