dpdk編譯

一、下載：http://core.dpdk.org/download/

 

二、編譯：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

 

三、問題：

1）pcap.h not found! 解決辦法：sudo apt-get install libpcap-de

 

2）hugepage設置失敗

修改/etc/default/grub 中的 GRUB_CMDLINE_LINUX，而後運行 grub 更新並重啓系統： //根據系統實際狀況設置default_hugepagesz=1G hugepagesz=1G hugepages=16 hugepagesz=2M hugepages=2048 iommu=pt intel_iommu=on isolcpus=1-13,15-27grub2-mkconfig -o /boot/grub2/grub.cfg
