exprt RTE_SDK=/home/dpdk-stable-19.11.10
export RTE_TARGET=arm64-armv8a-linuxapp-gcc
5.编译dpdk
make
make install
6.加载 uio、igb_uio
modprobe uio
cd /home/dpdk-stable-19.11.10/arm64-armv8a-linuxapp-gcc/kmod/
insmod igb_uio.ko

7.dpdk绑定网卡
cd /home/dpdk-stable-19.11.10/usertools
dpdk-devbind.py -s 可查看当前有哪些网卡

8.绑定大页内存
echo 52428 >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
cat /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

挂载大页内存
mkdir /mnt/huge
mount -t hugetlbfs nodev /mnt/huge/
9. 运行dpdk
/cd /home/dpdk-stable-19.11.10/build/app
./testpmd -l 1-3 -n 2 – -i --txd=1024 --rxd=1024 --txq=1 --rxq=1

出现 testpmd>
