[dpdk-dev] vfio error

[hamidreza Kheirabadi]

Hi,
I have a dpdk application which binds nic with igb_uio. My problem is
whenever the kernel updates, I must recompile igb_uio.ko as well.
I want to use vfio instead but I got an error:

Error: bind failed for 0000:06:00.0 - Cannot bind to driver vfio-pci
Error: unbind failed for 0000:06:00.0 - Cannot open
/sys/bus/pci/drivers//unbind

I used ubuntu 20.04 and dpdk-18.05 and use dpdk-setup.py helper script

Regards,
hamid
