Ahh I thought swr already used that. But if not it's probably not necessary for stable. Roland Am 19.07.2017 um 22:15 schrieb Rowley, Timothy O: > There weren’t any direct users of the avx512 features yet, but probably worth > proposing for stable pickup. > > Thanks. > > -Tim > >> On Jul 19,

There weren’t any direct users of the avx512 features yet, but probably worth proposing for stable pickup. Thanks. -Tim > On Jul 19, 2017, at 2:40 PM, Roland Scheidegger wrote: > > Makes sense to me. > Probably should go into stable? > > Reviewed-by: Roland Scheidegger

Makes sense to me. Probably should go into stable? Reviewed-by: Roland Scheidegger Am 19.07.2017 um 21:29 schrieb Tim Rowley: > cpuid.7 requires cx=0 to select the extended feature leaf. > > avx512 detection was using the non-indexed cpuid resulting > in random

[Mesa-dev] [PATCH] gallium/util: fix nondeterministic avx512 detection

cpuid.7 requires cx=0 to select the extended feature leaf. avx512 detection was using the non-indexed cpuid resulting in random non-detection of avx512. --- src/gallium/auxiliary/util/u_cpu_detect.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git
