安装 DPDK

下述使用 dpdk-setup.py tool 来进行安装。

sudo cd /opt
sudo wget http://fast.dpdk.org/rel/dpdk-18.08.tar.gz
sudo tar -zxvf dpdk-18.08.tar.gz
sudo cd /opt/dpdk-18.08/usertools

$ sudo ./dpdk-setup.py

[15] x86_64-native-linuxapp-gcc
[16] x86_64-native-linuxapp-icc
[17] x86_x32-native-linuxapp-gcc

----------------------------------------------------------
Step 2: Setup linuxapp environment
----------------------------------------------------------
[18] Insert IGB UIO module
[19] Insert VFIO module
[20] Insert KNI module
[21] Setup hugepage mappings for non-NUMA systems
[22] Setup hugepage mappings for NUMA systems
[23] Display current Ethernet/Crypto device settings
[24] Bind Ethernet/Crypto device to IGB UIO module
[25] Bind Ethernet/Crypto device to VFIO module
[26] Setup VFIO permissions

----------------------------------------------------------
Step 3: Run test application for linuxapp environment
----------------------------------------------------------
[27] Run test application ($RTE_TARGET/app/test)
[28] Run testpmd application in interactive mode ($RTE_TARGET/app/testpmd)

----------------------------------------------------------
Step 4: Other tools
----------------------------------------------------------
[29] List hugepage info from /proc/meminfo

----------------------------------------------------------
Step 5: Uninstall and system cleanup
----------------------------------------------------------
[30] Unbind devices from IGB UIO or VFIO driver
[31] Remove IGB UIO module
[32] Remove VFIO module
[33] Remove KNI module
[34] Remove hugepage mappings
