参考:
DPDK 网卡绑定和解绑
注意: 建议不要使用本文的eth0网卡绑定dpdk驱动.
1.进入DPDK目录:
$ cd dpdk/tools/
2.查看网卡信息:
$ ./dpdk-devbind.py --status
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
0000:00:1f.6 'Ethernet Connection (2) I219-LM' if=eth0 drv=e1000e unused=igb_uio
Other network devices
=====================
<none>
Crypto devices using DPDK-compatible driver
===========================================
<none>
Crypto devices using kernel driver
==================================
<none>
Other crypto devices
====================
<none>
3.绑定eth0网卡到dpdk到驱动:
$ ./dpdk-devbind.py --bind=igb_uio 00:1f.6
4.再次查看网卡状态, 发现该网卡已经绑定到dpdk驱动:
Network devices using DPDK-compatible driver
============================================
0000:00:1f.6 'Ethernet Connection (2) I219-LM' drv=igb_uio unused=
Network devices using kernel driver
===================================
<none>
Other network devices
=====================
<none>
Crypto devices using DPDK-compatible driver
===========================================
<none>
Crypto devices using kernel driver
==================================
<none>
Other crypto devices
====================
<none>
5.解绑eth0:
$ ./dpdk-devbind.py -u 00:1f.6
查看驱动信息, 此时网卡已经与dpdk驱动解绑:
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
<none>
Other network devices
=====================
0000:00:1f.6 'Ethernet Connection (2) I219-LM' unused=igb_uio
Crypto devices using DPDK-compatible driver
===========================================
<none>
Crypto devices using kernel driver
==================================
<none>
Other crypto devices
====================
<none>
如果需要重新将eth0绑定回kernel driver, 执行reboot即可:
$ reboot
