Curious if your work has any effect on the big endian + r600 issue [1]. I believe Christian Zigotzky (Cc'ed) was very passionate about getting his r600 working - perhaps he can give your patches a test ? ... just to make sure that things don't go even worse :) Cheers, Emil [1] https://bugs.freedesktop.org/show_bug.cgi?id=72877 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
