文章
所有示例，都放置在了
github.com/zartbot/learn_dpdk
配置SRIOV
改到root登录
su root
[root@netdev test]查看device-id
[root@netdev test]此步主要是获取
/dev/mst/mt4121_pciconf0然后检查相关的配置
[root@netdev test]需要将NUM_OF_VFS设置为4个、然后Enable
SRIOV_EN和UCTX_EN[root@netdev test]配置完成后重启整机
root创建VF
查看接口
[zartbot@netdev ~]$ sudo ibdev2netdev
mlx5_0 port 1 ==> ens17f0 (Up)
mlx5_1 port 1 ==> ens17f1 (Up)查看最多能够支持的VF数量
[zartbot@netdev ~]$ cat /sys/class/net/ens17f0/device/sriov_totalvfs
4
[zartbot@netdev ~]$ cat /sys/class/net/ens17f1/device/sriov_totalvfs
4启用VF
echo 4 | sudo tee /sys/class/net/ens17f1/device/sriov_numvfs
echo 4 | sudo tee /sys/class/net/ens17f0/device/sriov_numvfs然后lspci就可以看到网卡了
[zartbot@netdev ~]$ lspci | grep Mellanox
