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
