Subject: [dpdk-dev] [PATCH v6 2/3] app/test: run-time dispatch over memcpy perf test
Date: Thu, 5 Oct 2017 06:58:30 +0800 [thread overview]
Message-ID: <1507157911-8702-3-git-send-email-xiaoyun.li@intel.com> (raw)
In-Reply-To: <1507157911-8702-1-git-send-email-xiaoyun.li@intel.com>
This patch modifies assignment of alignment unit from build-time
to run-time based on CPU flags that machine supports.
