I am trying to bind an interface eth0 to vfio driver. I have made sure
iommu is enabled in grub and kernel. I have loaded the module vfio-pci. Ran
following commands
#modprobe vfio-pci
#chmod a+x /dev/vfio
#chmod 0666 /dev/vfio/*
#export DPDK_DIR=/usr/src/dpdk-stable-17.11.4
#sudo $DPDK_DIR/usertools/dpdk-devbind.py --bind=vfio-pci 02:01.0
I got following error:
Error: bind failed for 0000:02:01.0 - Cannot bind to driver vfio-pci
I checked the error in dmesg:
Got :
[ 1815.793823] vfio-pci: probe of 0000:02:01.0 failed with error -22
let me know the reason.
Best Regards,
Ramzah Rehman
