Hello,
I'm trying to set up PF using DPDK in addition to SR-IOV connection to the VMs. Currently (before enabling SR-IOV VFs ) all interfaces is using DPDK VFIO-PCI driver. I've enabled below patch to the VFIO driver in order to create VF on the Physical port: https://patchwork.kernel.org/patch/10103353/ The problem is that once I bind VFIO driver to the created VF I expect to see new device node /dev/vfio/X with the relevant IOMMU group. In my setup this device note isn't created therefore I can't connect the VF to VM using Libvirt which is looking for this file. The sequence I did is: #Create 4 VF on the PF echo '4' > /sys/bus/pci/devices/0000\:06\:00.0/sriov_numvfs #Unbind the 4 VF from the default driver echo "0000:06:10.0" > /sys/bus/pci/drivers/ixgbevf/unbind echo "0000:06:10.2" > /sys/bus/pci/drivers/ixgbevf/unbind echo "0000:06:10.4" > /sys/bus/pci/drivers/ixgbevf/unbind echo "0000:06:10.6" > /sys/bus/pci/drivers/ixgbevf/unbind #Bind the VF to VFIO-PCI driver echo "8086 15c5" > /sys/bus/pci/drivers/vfio-pci/new_id #After this command I expect to see new /dev/vfio/X file for each VF. I can see that each VF is in different IOMMU group. What I'm missing here ? Is there any other option to connect VM with SR-IOV once using DPDK driver on the PF ? Regards, Amir.
