编译

http://core.dpdk.org/doc/quick-start/

安装python3

安装ninja

yum install ninja-build

安装meson

pip3 install meson

开始编译

  tar xf dpdk.tar.gz
  cd dpdk
  meson build
  ninja -C build

确定配置好大页内存

  mkdir -p /dev/hugepages
  mountpoint -q /dev/hugepages || mount -t hugetlbfs nodev /dev/hugepages
  echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

运行测试程序

iface需要对应机器上支持的网卡名称

  build/app/dpdk-testpmd -c7 --vdev=net_pcap0,iface=eth0 --vdev=net_pcap1,iface=eth1 -- -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048

  testpmd> show port stats all

遇到的错误

ERROR: Problem encountered: missing python module: elftools

pip3 install pyelftools

error while loading shared libraries: libatomic.so.1: cannot open shared object file

yum install libatomic

DPDK is running on a NUMA system, but is compiled without NUMA support.

这个不算问题，如果需要dpdk自己支持NUMA，需要在编译前安装对应的开发库

dnf install numactl-devel
