I have been trying to bind to vfio-pci using usertools/dpdk-devbind.py but am unable to do so. The reason behind this is that I am unable to write in /sys/bus/pci/drivers/vfio-pci/bind. Upon searching solutions I tried a couple of things such as setting iommu=pt and intel_iommu=on and ensured vt-d is enabled. Along with this I have made sure that the vfio-pci module is correctly loaded. I have also tried
chmod 666 /sys/bus/pci/drivers/vfio-pci/bind So that I have permissions to write in this file. The error I get when I use usertools/dpdk-devbind.py to bind is this: Error: bind failed for 0000:b7:00.1 - Cannot bind to driver vfio-pci The details of 0000:b7:00.1 are as follows: Ethernet Connection X722 for 10GBASE-T 37d2' if=eno6 drv=i40e I have also unbinded The pci bridge to which 0000:b7:00.1 was connected. What more can be done to resolve this? Regards, Sarosh Arif
