Subject: [dpdk-dev] [PATCH v2 0/3] improve i40e vpmd
Date: Thu, 14 Apr 2016 17:02:34 +0100 [thread overview]
Message-ID: <1460649757-11862-1-git-send-email-bruce.richardson@intel.com> (raw)
In-Reply-To: <1460628921-25635-1-git-send-email-bruce.richardson@intel.com>
This patchset improves the performance of the i40e SSE pmd by removing
operations that triggered CPU stalls. It also shortens the code and
cleans it up a little.
The base requirement for using the SSE code path has been pushed up to
SSE4.1 from SSE3, due to the use of the blend instruction. The instruction
set level is now checked at runtime as part of the driver selection process
Bruce Richardson (3):
i40e: require SSE4.1 support for vector driver
i40e: improve performance of vector PMD
i40e: simplify SSE packet length extraction code
drivers/net/i40e/Makefile | 6 ++++
drivers/net/i40e/i40e_rxtx_vec.c | 59 ++++++++++++++--------------------------
