glibc uses the cache size information returned by cpuid to perform optimizations. For instance, copy operations which would pollute too much of the cache because they are large will use non-temporal instructions. There are real performance benefits. Even the synthetic CPU provided by qemu should have a more realistic value. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEARECAAYFAkxWzPsACgkQ2ijCOnn/RHQ2JwCeJsgXHxkWG/PYS8JQRiGM1UFF m78Ani9kmnKJyru/wh764NSgHSQx+WjU =6qet -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
