DRM uses arrays of handles and offsets (see struct drm_framebuffer). A handle references a gem object (roughly the same as a resource), and the offset specifies the start of the plane within the gem object. That allows both a single gem object with planes stored at different offsets and one gem object per plane. virtio-video could do the same, or pick one of the two approaches and support only that. cheers, Gerd _______________________________________________ Spice-devel mailing list Spice-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/spice-devel
