1.概述

此文档介绍DPDK在ubuntu上的安装步骤和FAQ

1.1 介绍

待补充

1.2 简介

待补充

2.DPDK安装

2.1 软件版本

DPDK：dpdk-19.08.2

ubuntu版本：18.04

linux内核：5.4.0-150-generic

2.2 系统环境准备

依赖工具安装

sudo apt install build-essential

#编译程序必须的软件包，如果想在Ubuntu中编译c/c++程序，只需要安装该软件包

sudo apt-get install libnuma-dev

配置大页内存，开启immon功能

sudo vim /etc/default/grub

在GRUB_CMDLINE_LINUX末尾追加：

GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg auto noprompt priority=critical locale=en_US hugepages=512 intel_iommu=on iommu=pt"

重新生成引导配置

sudo grub-mkconfig -o /boot/grub/grub.cfg

重启并验证

cat /proc/meminfo |grep -i HugePages

dmesg | grep DMAR

2.3 编译安装DPDK

设置环境变量

cd dpdk-stable-19.08.2

export RTE_SDK=`pwd`

export RTE_TARGET=x86_64-native-linuxapp-gcc

===============================================================================

运行dpdk-setup.sh 编译

sunny@ubuntu:~/dpdk-stable-19.08.2$ cd usertools/

sunny@ubuntu:~/dpdk-stable-19.08.2/usertools$ ./dpdk-setup.sh

===============================================================================

Option: 编译选项选择36

[36] x86_64-native-linuxapp-gcc

Option: 36

回显：

===============================================================================

加载驱动，选择43

[43] Insert IGB UIO module

Option: 43

回显：

#Unloading any existing DPDK UIO module

#Loading uio module

#Loading DPDK UIO module

===============================================================================

配置大页内存46

[46] Setup hugepage mappings for non-NUMA systems

Option: 46

回显：

#Removing currently reserved hugepages

#Unmounting /mnt/huge and removing directory

Number of pages: 512

#Reserving hugepages

#Creating /mnt/huge and mounting as hugetlbfs

===============================================================================

查看网卡状态48，“0000:03:00.0”即网卡PCI地址，后续配置用”03:00.0”就可以

[48] Display current Ethernet/Baseband/Crypto device settings

Option: 48

回显：

#Network devices using DPDK-compatible driver

============================================

#0000:03:00.0 'VMXNET3 Ethernet Controller 07b0' drv=igb_uio unused=vmxnet3,vfio-pci

#Network devices using kernel driver

===================================

#0000:02:01.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' if=ens33 drv=e1000 unused=igb_uio,vfio-pci *Active*

#No 'Baseband' devices detected

===============================================================================

绑定网卡49

需要先将网卡down:

---------------------------------sunny@ubuntu:~/dpdk-stable-19.08.2/usertools$ ifconfig ens160 down

[49] Bind Ethernet/Baseband/Crypto device to IGB UIO module

Option: 49

回显：

Enter PCI address of device to bind to IGB UIO driver: 03:00.0

===============================================================================

运行测试程序53

[53] Run testpmd application in interactive mode ($RTE_TARGET/app/testpmd)

Option: 53

# Enter hex bitmask of cores to execute testpmd app on

# Example: to execute app on cores 0 to 7, enter 0xff

bitmask: 7

#Launching app

#EAL: Detected 4 lcore(s)

#EAL: Detected 1 NUMA nodes

。。。。。。。。。。。。。。。

#Configuring Port 0 (socket 0)

#Port 0: 00:0C:29:71:E5:57

#Checking link statuses...

#Done

在命令行启动网卡

3.FAQ

1、如果编译安装过程中，绑定网卡可能会遇到python执行不了

解决方法：可能的原因是你本地安装的是python3，但是绑定网卡的执行程序调用的是python，可以去usertools目录下，修改dpdk-devbind.py文件，把第一行的python修改为python3

2、参考连接如下：但是要注意第三步的环境变量配置需要修改为 export RTE_TARGET=x86_64-native-linuxapp-gcc

3、查看网卡的总线信息，先安装工具apt install ethtool

ethtool -i eth0

driver: vmxnet3
