If I didn't put the DRM_INFO there, everything would have continued to work and nobody would have complained. I personally prefer keeping the size as the compressed size like you did here: https://bugs.freedesktop.org/show_bug.cgi?id=88975#c1 but Chris already reviewed this so nuts to me. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
