I need to find out how the quant mode affects the range of > values. My guess is that QUANT_MODE determines the position of fixed point for internal calculations in hw. Quantization precision 1/4096 means 12 bits, and it looks like we have 11 bits before the point in that case, with 23 bits total. So if we need to increase the range, we have to move the point lowering the precision. I've tried 1/256 and other values on evergreen for initial implementation of that patch in hope that it'll be enough, but IIRC 1/4096 fixed more tests (though possibly some test results were simply random). If some tests are really failing due to lower precision, I guess we might want to adjust QUANT_MODE dynamically. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
