Subject: [dpdk-dev] [PATCH 0/4] DPDK memcpy optimization
Date: Mon, 19 Jan 2015 09:53:30 +0800 [thread overview]
Message-ID: <1421632414-10027-1-git-send-email-zhihong.wang@intel.com> (raw)
This patch set optimizes memcpy for DPDK for both SSE and AVX platforms.
It also extends memcpy test coverage with unaligned cases and more test points.
Optimization techniques are summarized below:
1. Utilize full cache bandwidth
2. Enforce aligned stores
3. Apply load address alignment based on architecture features
4. Make load/store address available as early as possible
5. General optimization techniques like inlining, branch reducing, prefetch pattern access
Zhihong Wang (4):
Disabled VTA for memcpy test in app/test/Makefile
Removed unnecessary test cases in test_memcpy.c
Extended test coverage in test_memcpy_perf.c
Optimized memcpy in arch/x86/rte_memcpy.h for both SSE and AVX
platforms
