Subject: [dpdk-dev] [RFC v2 0/7] PMD driver for AF_XDP
Date: Thu, 8 Mar 2018 21:52:42 +0800 [thread overview]
Message-ID: <20180308135249.28187-1-qi.z.zhang@intel.com> (raw)
v2:
- fix lisence header
- clean up bpf dependency, bpf program is embedded, no "xdpsock_kern.o" required
- clean up make file, only linux_header is required
- fix all the compile warning.
- fix packet number return in Tx.
The RFC patches add a new PMD driver for AF_XDP which is a proposed
faster version of AF_PACKET interface in Linux, see below link for
detail AF_XDP introduction:
https://fosdem.org/2018/schedule/event/af_xdp/
https://lwn.net/Articles/745934/
This patchset is base on v18.02.
It also require a linux kernel that have below AF_XDP RFC patches be
applied.

There is no clean upstream target yet since kernel patch is still in
RFC stage, The purpose of the patchset is just for anyone that want to
eveluate af_xdp with DPDK application and get feedback for further
improvement.
To try with the new PMD
1. compile and install the kernel with above patches applied.
(commit 91e6dd8284256e should work)
2. configure $LINUX_HEADER_DIR (dir of "make headers_install")
at driver/net/af_xdp/Makefile
3. make sure libelf and libbpf is installed.
4. testpmd cmdline example:
./testpmd -c 0x3 -n 4 --vdev 'eth_af_xdp,iface=eth0' -- -i --mbuf-size=1856 --mp-flags=65
BTW, performance test shows our PMD can reach 94%~98% of the orignal
benchmark when share memory is enabled.
