I would like to propose an enhancement for vpp to work with dpdk multicore-crypto scheduler ( http://doc.dpdk.org/guides-18.02/cryptodevs/scheduler.html ).
For the software crypto pmd to be scheduled on multiple cores the following dpdk configuration is required: vdev crypto_scheduler,slave=aesni_mb_1,slave=aesni_mb_2,mode=multi-core,corelist=3-4,ordering=enable This does not work directly with base VPP code, the following enhancements are required 1. VPP Changes: - Recognize slave-lcore corelist assigned for multi-core crypto and pass the configuration during dpdk plugin device init(startup.conf) - Start the multi-core crypto scheduler for the correct device_id. 2. DPDK Patch - Enable RTE_LIBRTE_PMD_CRYPTO_SCHEDULER - Enable PER_SLAVE_BUFF_SIZE to be configurable from start parameters(slave_buff_size=8192) - Ordering Fix for Multi Producer Queue A patch was performance tested off VPP 17.10 (DPDK 17.08) release with 2,3,4 crypto cores. If everyone thinks this merits going into 18.07.1, i'll initiate a review (there have been a couple of posts on this already)
