2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang1-0/+6
This patch aims to improve decap performance by reducing expensive hash_get callings as less as possible using AVX512 on XEON. e.g. vxlan, vxlan_gpe, geneve, gtpu. For the existing code, if vtep4 of the current packet match the last vtep4_key_t well, expensive hash computation can be avoided and the code returns directly. This patch improves tunnel decap multiple flows case greatly by leveraging 512bit vector register on XEON accommodating 8 vtep4_keys. It enhances the possiblity of avoiding unnecessary hash computing once hash key of the current packet hits any one of 8 in the 512bit cache. The oldest element in vtep4_cache_t is updated in round-robin order. vlib_get_buffers is also leveraged in the meanwhile.

2020-02-13vppinfra: add 128-bit and 512-bit a ^ b ^ c shortcutDamjan Marion1-0/+7
This allows us to combine 2 XOR operations into signle instruction which makes difference in crypto op: - in x86, by using ternary logic instruction - on ARM, by using EOR3 instruction (available with sha3 feature) Type: refactor Change-Id: Ibdf9001840399d2f838d491ca81b57cbd8430433 Signed-off-by: Damjan Marion <damjan.marion@gmail.com>
