Time for heuristics and testing! :) How about (last_size + base_size) / 2? You could lose days trying to polish the corner case ;) If it weren't for cmdparser you would just do batch chaining - worth it for !gen7? -Chris _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
