Thank you Alex, it is under works. But could you offer a git tree? Can't find them in drm-next-4.1-wip. I couldn't apply patches to my old former drm-next-3.19 and now moved (during system change) to drm-next-4.1-wip tree any longer?! - Any hints? Maybe I have to work with a new checked out one. Or could it be, that I only have forgotten to add me to the git 'system'? Have to investigate. -Dieter
