[dpdk-dev] [PATCH] mk: disable SCHED_VECTOR in the default config

[Christian Ehrhardt]

Hi Thomas,
no it is not fixed by that commit.
Even with it applied the remaining include subsequently at
rte_vect.h:67 pulls in x86intrin.h which still ends up including
smmintrin.h.
Long story short is that the mentioned issues like the following still occur:

/usr/lib/gcc/x86_64-linux-gnu/5/include/smmintrin.h:67:1: error:
inlining failed in call to always_inline ‘_mm_testz_si128’: target
specific option mismatch
 _mm_testz_si128 (__m128i __M, __m128i __V)

So I'd ask to still disable CONFIG_RTE_SCHED_VECTOR in the default
config via my patch.
Kind Regards,
Christian
