From: Pablo de Lara Date: Wed, 13 Dec 2017 13:14:08 +0000 (+0000) Subject: app/crypto-perf: support IMIX X-Git-Tag: spdx-start~114 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=27c2e74719614df32e5358b9adfbed013ac7991c;p=dpdk.git app/crypto-perf: support IMIX Add support for IMIX performance tests, where a distribution of various packet sizes can be submitted to a crypto device, testing a closer to a real world scenario. A sequence of packet sizes, selected randomly from a list of packet sizes (with "buffer-sz" parameter) with a list of the weights per packet size (using "imix" parameter), is generated (the length of this sequence is the same length as the pool, set with "pool-sz" parameter). This sequence is used repeteadly for all the crypto operations submitted to the crypto device (with "--total-ops" parameter).
