Enumeration Type Documentation enum rte_vect_max_simd The max SIMD bitwidth value to limit vector path selection. Enumerator RTE_VECT_SIMD_DISABLED Limits path selection to scalar, disables all vector paths. RTE_VECT_SIMD_128 Limits path selection to SSE/NEON/Altivec or below. RTE_VECT_SIMD_256 Limits path selection to AVX2 or below. RTE_VECT_SIMD_512 Limits path selection to AVX512 or below. RTE_VECT_SIMD_MAX Disables limiting by max SIMD bitwidth, allows all suitable paths. This value is used as it is a large number and a power of 2. Definition at line 198 of file rte_vect.h. Function Documentation uint16_t rte_vect_get_max_simd_bitwidth (void) Get the supported SIMD bitwidth. Returns uint16_t bitwidth. int rte_vect_set_max_simd_bitwidth (uint16_t bitwidth) Set the supported SIMD bitwidth. This API should only be called once at initialization, before EAL init. Parameters bitwidth uint16_t bitwidth. Returns * 0 on success. * -EINVAL on invalid bitwidth parameter. * -EPERM if bitwidth is forced.
