R6xx and r7xx are really all you need to worry about in this case. R1xx-r5xx UMS uses a different kernel interface for command submission and evergreen and later don't have UMS drm support. UMS r6xx/r7xx support used the same kernel interface for command submission but the kernel side was much simpler. Additionally, UMS requires the old non-gallium 3D drivers. It sounds like some other change in the ddx broke UMS support for r6xx/r7xx. UMS support was dropped for xf86-video-ati 7.0.0, so we mostly want to try and avoid breaking things for users with ancient userspace stacks and a new kernel. That said, I'm not sure there are that many UMS users left. Alex
Wouldn't it be a good idea to finally get ride of the old UMS stuff inside the kernel driver?
Maybe making it a config option with default N as first step and then wait for a year or two and see if anybody starts complaining?
