I spotted an error in github actions for linux clang test 3.16 scan, however it looks unrelated. I re-ran the patch through github and it passes fine so pls ignore the patchwork result for this patch. Passing test below. https://github.com/istokes/ovs/actions/runs/1035072585 Thanks Ian > --- > NEWS | 1 + > lib/dpdk.c | 2 ++ > 2 files changed, 3 insertions(+) > > diff --git a/NEWS b/NEWS > index 225eb445c..99baca706 100644 > --- a/NEWS > +++ b/NEWS > @@ -40,6 +40,7 @@ Post-v2.15.0 > traffic. > * Add build time configure command to enable auto-validatior as default > miniflow implementation at build time. > + * Cache results for CPU ISA checks, reduces overhead on repeated > lookups. > - ovs-ctl: > * New option '--no-record-hostname' to disable hostname configuration > in ovsdb on startup. > diff --git a/lib/dpdk.c b/lib/dpdk.c > index 9de2af58e..1b8f8e55b 100644 > --- a/lib/dpdk.c > +++ b/lib/dpdk.c > @@ -706,6 +706,8 @@ dpdk_get_cpu_has_isa(const char *arch, const char > *feature) > #if __x86_64__ > /* CPU flags only defined for the architecture that support it. */ > CHECK_CPU_FEATURE(feature, "avx512f", RTE_CPUFLAG_AVX512F); > + CHECK_CPU_FEATURE(feature, "avx512bw", RTE_CPUFLAG_AVX512BW); > + CHECK_CPU_FEATURE(feature, "avx512vbmi", RTE_CPUFLAG_AVX512VBMI); > CHECK_CPU_FEATURE(feature, "avx512vpopcntdq", > RTE_CPUFLAG_AVX512VPOPCNTDQ); > CHECK_CPU_FEATURE(feature, "bmi2", RTE_CPUFLAG_BMI2); > #endif > -- > 2.25.1 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
