Hi All I am not able to bind 82599 to either uio_pci_generic or vfio-pci successfully. Any help greatly appreciated, I am completely stuck at this initial step.
*1) uio_pci_generic* : tools/dpdk-devbind.py script reports success but it is not detected by EAL on initialisation, still ixgbe driver is detected. here is relevant console output [root@unassigned dpdk-16.11]# tools/dpdk-devbind.py --status Network devices using DPDK-compatible driver ============================================ 0000:01:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=uio_pci_generic unused=ixgbe,vfio-pci 0000:01:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=uio_pci_generic unused=ixgbe,vfio-pci [root@unassigned dpdk-16.11]# examples/l2fwd/build/l2fwd -c f -n 2 p ffff EAL: Detected 8 lcore(s) EAL: No free hugepages reported in hugepages-1048576kB EAL: Probing VFIO support...
