Hi guys,
i did sent a patch to add GM206 to the ddx also but looks like it got missed you can find it here.

http://lists.freedesktop.org/archives/nouveau/2015-February/020144.html

But as said no acceleration yet.

I'll ping in that older mail-thread as probably mail was overlooked (probably i should have mentioned ddx in my subject)
