2、对大页内存进行设置，直接在cmdline 里进行设置；
vim /etc/default/grub
GRUB_CMDLINE_LINUX="default_hugepagesz=1G hugepagesz=1G hugepages=64"
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ sudo grub-mkconfig -o /boot/grub/grub.cfg

Found memtest86+ image: /boot/memtest86+.elf
Found memtest86+ image: /boot/memtest86+.bin
done
设置完成后重新启动机器；
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ sudo reboot
查看设置的是否生效；
noc@noc-NF5270M4:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.3.0-28-generic root=/dev/mapper/ubuntu--vg-root ro default_hugepagesz=1G hugepagesz=1G hugepages=64 quiet splash vt.handoff=1
查看大页内存是否正常的进行了挂载；
noc@noc-NF5270M4:~$ mount | grep huge
cgroup on /sys/fs/cgroup/hugetlb type cgroup (rw,nosuid,nodev,noexec,relatime,hugetlb)
hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime,pagesize=1024M)
3、查看是否加载了uio模块
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ lsmod | grep uio
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ lsmod | grep igb
igb 221184 0
i2c_algo_bit 16384 2 igb,ast
dca 16384 3 igb,ioatdma,ixgbe
加载uio 模块，加载编译好的igb_uio.ko 内核文件；
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ sudo modprobe uio
[sudo] password for noc:
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ sudo insmod kmod/igb_uio.ko
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ lsmod | grep igb
igb_uio 20480 0
uio 20480 1 igb_uio
igb 221184 0
i2c_algo_bit 16384 2 igb,ast
dca 16384 3 igb,ioatdma,ixgbe
4、尝试启动testpmd 管理工具；
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ ./app/testpmd -- i
EAL: Detected 16 lcore(s)
EAL: Detected 2 NUMA nodes

Aborted (core dumped)
启动失败，查看错误为未找到合适的物理设备，所以导致失败；
5、绑定物理设备到uio 模块上使用；
5、1 查找需要的设备ID信息；
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ lspci | grep Eth
02:00.0 Ethernet controller: Mellanox Technologies MT27500 Family [ConnectX-3]
04:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
04:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
84:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
84:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
5、2查找设备的厂商ID与产品ID；
noc@noc-NF5270M4:~/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc$ lspci -vmn
Device: 84:00.0
Class: 0200
Vendor: 8086
Device: 10fb
SVendor: 8086
SDevice: 000c
PhySlot: 0-8
Rev: 01
NUMANode: 1
Device: 84:00.1
Class: 0200
Vendor: 8086
Device: 10fb
SVendor: 8086
SDevice: 000c
PhySlot: 0-8
Rev: 01
NUMANode: 1
5、3 将设备绑定到uio 模块里进行加载；
root@noc-NF5270M4:/home/noc/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc# echo "8086 10fb" > /sys/bus/pci/drivers/igb_uio/new_id

root@noc-NF5270M4:/home/noc/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc# echo 0000:84:00.1 > /sys/bus/pci/drivers/ixgbe/unbind
root@noc-NF5270M4:/home/noc/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc# echo 0000:84:00.1 > /sys/bus/pci/drivers/igb_uio/bind

查看是否绑定进来；
root@noc-NF5270M4:/home/noc/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc# ll /sys/bus/pci/drivers/igb_uio/

6、再次用交互式启动，查看启动情况；
root@noc-NF5270M4:/home/noc/dpdk-stable-18.11.8/x86_64-native-linuxapp-gcc# ./app/testpmd -- -i
