I bound a couple of ports using the i40e driver to DPDK using vfio-pci kernel driver, and then did a chmod on the /dev/vfio/ nodes for them to give the user access. I also gave the user rw access to the hugepage mount point I had created. Thereafter testpmd ran fine as a non-root user and I was able to put traffic through it. Regards, /Bruce
