• dpdk编译


    1、下载:http://core.dpdk.org/download/

    2、编译:http://core.dpdk.org/doc/quick-start/

     Extract sources

      tar xf dpdk.tar.gz
      cd dpdk
    

    Enable pcap (libpcap headers are required).

      make config T=x86_64-native-linuxapp-gcc
      sed -ri 's,(PMD_PCAP=).*,1y,' build/.config
    

    Build libraries and test application (Linux headers may be needed with default config).

      make
    

    Reserve huge pages memory.

      mkdir -p /mnt/huge
      mount -t hugetlbfs nodev /mnt/huge
      echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
    

    Run poll-mode driver test (with a cable between ports).

      build/app/testpmd -c1 -n3 --vdev=net_pcap0,iface=eth0  --vdev=net_pcap1,iface=eth1 -- -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048

    Some sample applications can be tested after building them.

      make -C examples RTE_SDK=$(pwd) RTE_TARGET=build O=$(pwd)/build/examples

    3、问题:

    1)pcap.h not found! 解决办法:sudo apt-get install libpcap-de

    2)hugepage设置失败

    修改/etc/default/grub 中的 GRUB_CMDLINE_LINUX,然后运行 grub 更新并重启系统: //根据系统实际情况设置
    default_hugepagesz=1G hugepagesz=1G hugepages=16 hugepagesz=2M hugepages=2048 iommu=pt intel_iommu=on isolcpus=1-13,15-27
    grub2-mkconfig -o /boot/grub2/grub.cfg
