Hi, I need some help getting DPDK working. I am running Ubuntu 20.04 with a modified Linux 5.4 kernel, but I have also tried the stock Ubuntu 5.15 kernel with the same results.
Here is my NIC info from lspci: 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (3) I219-LM (rev 09) I built and installed DPDK from source, and applied the following boot flags: "intel_iommu=on iommu=pt" After booting I did the following as root: echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages ifconfig enp0s31f6 down dpdk-devbind.py --bind=vfio-pci 0000:00:1f.6 All of this appeared to work. I tried running the "skeleton" example program and got the following output: sudo ./build/basicfwd EAL: Detected CPU lcores: 16 EAL: Detected NUMA nodes: 1 EAL: Detected shared linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized EAL: 0000:00:1f.6 VFIO group is not viable! Not all devices in IOMMU group bound to VFIO or unbound EAL: Requested device 0000:00:1f.6 cannot be used TELEMETRY: No legacy callbacks, legacy socket not created EAL: Error - exiting with code: 1 Cause: Error: number of ports must be even I'm not at all familiar with DPDK or VFIO. What might the problem be? -Alan
