配置DPDK (初学者适用)

陈新 2016/4/29

1. dpdk-1.8.0 文件夹中找到tools文件夹, 其中找到 setup.sh, 进入特权模式下运行.

[root@localhost tools]# ./setup.sh 2. 应该输入9，选择x86_64-native-linuxapp-gcc进行编译

3. 载入IGB组件, 输入11.

4. 设置页大小, 输入14, 先设置位1024，即1024*2MB的页大小

5. 选择[22] List hugepage info from /proc/meminfo, 可以查看页大小，以及多少页是空闲的.

6. 查看当前网卡状态, 选择[16] Display current Ethernet device settings.

7. 绑定网卡

选择[17] Bind Ethernet device to IGB UIO module. 输入网卡前面的数字序号，即可绑定该网卡. 针对网卡绑定, 我绑定了所有非active状态的网卡归DPDK使用.

8. dpdk的配置都已经结束了，下面可以运行一下dpdk自带的示例程序，比如说testpmd： 选择[21] Run testpmd application in interactive mode ($RTE_TARGET/app/testpmd) 输入f, 回车: testpmd> start testpmd> stop
