    Yep all Git.

          How does this compare to the existing 1d tiling which is on by default in most radeons lately?

          I noticed the comparison was no tiling v. 2d tiling. 1d tiling was already a substantial improvement over linear mode.

            1d wasn't a substantial improvement (despite maybe some degenerative case), 2d tiling is a way bigger improvement than 1d.

              When will this hit Fedora?

              Right now, in Fedora 17 it says "ColorTiling2D is not a valid option".

                Btw. what about OpenVG/OpenGL ES benchmarks? Are they possible?
                (g-truc.net called MESA best desktop OpenGL ES implementation , so it's good excuse for some benchmark right? )
                I'm not sure what he'd use for benchmarking since I can't think of any desktop software that uses OVG.

                  Tried this with git-mesa/ddx/libdrm an 3.2.12 kernel with the kernel patches from the mailing list
                  message on earlyer article. Didn't work after opengl app opens screen freezes (mouse moves)
                  and dmesg starts to sprout the invalid command stream errors...

                    Well you obviously have something wrong on your side, probably not using the correct kernel, or not using correct mesa ... I extensively tested all this on GPU from HD2xxx to HD6xxx so i know it works with many GL applications for a fact, if you can't even get gears or nexuiz going there is something wrong on your side.

                      Jerome, you're probably right, but I'm having the same thing here (Linux 3.3 vanilla, libdrm, mesa and xf86-video-ati all from git yesterday, HD 4550). I'm running the vanilla 3.3 kernel and don't remember now whether that has tiling patches in it, so it COULD be a different bug (see also http://phoronix.com/forums/showthrea...356#post254356).

                      Any suggestions for where to start looking for problems?
