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.
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...
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?
