Should I add marco in kernel include/uapi/linux/virtio_gpu.h?
They are used at VIRGL_RENDERER_UNSTABLE_APIS in virglrender.
enum virgl_renderer_capset {
VIRGL_RENDERER_CAPSET_VIRGL = 1,
VIRGL_RENDERER_CAPSET_VIRGL2 = 2,
/* 3 is reserved for gfxstream */
VIRGL_RENDERER_CAPSET_VENUS = 4,
/* 5 is reserved for cross-domain */
VIRGL_RENDERER_CAPSET_DRM = 6,
};
