[dpdk-users] Unable to bind intel NIC X710

[Hezy Abudy]

Hi All,

I am trying to bind this nic I40E:

Ethernet Controller X710 for 10GbE backplane 1581


my OS is ubuntu 18.04
kernel: 4.15.0-74-generic


I used dpdk-setup.sh to Insert VFIO module.
i also add iommu=on to grub file.


running devbind command:

sudo ./dpdk-devbind.py -b vfio-pci 02:00.1

i Got this erros:

Error: bind failed for 0000:02:00.1 - Cannot bind to driver vfio-pci


dmesg output:

[ 5091.393436] vfio-pci*: probe of 0000:02:00.1 failed with error -22*


Thanks,

Hezy.
