I think we're getting there. Found some issues with patch 3 still. Besides that I think we need: - r-b/ack from Sean Paul, as an ack that he's happy with what this means for drm_hwcomposer (and that the hwc patches look ok, too). - acks/t-b from everyone who's run this, the more the better. This is a big uabi extension, making the effort by everyone explicit is important. - ack from Brian that he can use the out-fence stuff for his writeback support. Probably need to add a for_each_connector loop to prepare/complete_signalling (and drop the crtc_ in there, but Brian can do that).
