Yeah, this should all work without ring and status pages ...

If this is cpu edp, you might want to try the giant modeset-rework branch
of mine at:
http://cgit.freedesktop.org/~danvet/drm/log/?h=modeset-rework
This fixes (among tons of prep work) and ordering issue with our cpu edp
code, which at least on ivb results in stuck pipes (and black screens).
Yours, Daniel
