DRM context is enabled using a new virtio-gpu-gl device option "drm_native_context=3Don". Unlike Virgl and Venus contexts that operate on application API level, DRM native contexts work on a kernel UAPI level. This lower level results in a lightweight context implementations that yield better performance. Reviewed-by: Akihiko Odaki Acked-by: Michael S.
