That's precisely what, where and why we want to clarify, correct the
spec or add a new one.
James, Daniel, can we hear your input on the following ?
The way I read the spec(s) EGL_EXT_device_drm can effectively be
either the card/primary or render node, while EGL_EXT_output_drm must
be the card one.
Can/should we restrict the former to render only, do you see any
implications that will bring ?
Or should we just roll out another spec for the "render only" case ?
Thanks
Emil
