I think this might need rebasing on top of I'm glad there are tests, but the internal accuracy of the CAIRO_FORMAT_RGB24 is only 8 bits, so it wouldn't test this properly. Fortunately we will start using CAIRO_FORMAT_RGB96F and RGBA128F soon. :) See https://patchwork.freedesktop.org/patch/284507/ We should be able to convert native float to half float with an intrinsic. ~Maarten _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
