Exactly, thats why anything modesetting-related must be disabled for
renderD#. Looking at the virtio-gpu device-specific ioctls I don't
think there is anything doing modesetting (which we would have to leave
out), so we can apply DRM_RENDER_ALLOW everythere I think. Or maybe
there is a global switch to flip DRM_RENDER_ALLOW for the whole list ...
cheers,
Gerd
