Hmm, s64 not u64 as I > presumed. So better to check <= 0. by division by 0 I guess you mean here: div64_u64(mul_u32_u32(4 * size, 1000 * 1000 * 1000), t[1] + 2 * t[2] + t[3]) >> 20); why are you testing t[0]? Did I miss anything else? Andi _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
