Hi all,

>VFIO is a much better solution.

Stephen is right; moreover, DPDK documentation says explicitly that
...
"If UEFI secure boot is enabled, the Linux kernel may disallow the use of UIO on the system. Therefore, devices for use by DPDK should be bound to the vfio-pci kernel module rather than igb_uio or uio_pci_generic. For more details see Binding and Unbinding Network Ports to/from the Kernel Modules below."
...
See section 4.1, "UIO", in:
https://doc.dpdk.org/guides/linux_gsg/linux_drivers.html

Regards,
Rami Rosen
