Hi, Martin, How do you bind the device ? is it with igb_uio/vfio ? In case this is what you do - can you please try with uio_pci_generic and tell if you get the same error ? The uio_pci_generic should be included in your distro as one of the kernel modules, you need just to do modprobe uio_pci_generic before binding to DPDK.

I did some debugging and it turned out that i40e drivers were not linked when building the dpdk. I fixed this, but I have encountered another problem... Although the cards are discovered, I get this error: > EAL: pci_map_resource(): cannot mmap(102, 0x7fffc0000000, 0x1000000, > 0x0): Operation not permitted (0xffffffffffffffff) I've seen some information about his mmap-related behavior and some hints about setting iomem=relaxed in grub. As making changes to grub means completely reinstalling my machine, I would like to ask, if you think that this could be the way to go. Thanks, Martin
