Among all three DPDK drivers: (1) uio_pci_generic is not supported on X710 (http://dpdk.org/dev/patchwork/patch/19820/), and driver bind failed; (2) igb_uio will work perfectly, but does not come with RHEL 7.3 kernel directly. Have to build from source to have it; (3) vfio-pci, which is the only option left. According to https://wiki.fd.io/view/VPP/Command-line_Arguments#.22dpdk.22_parameters, vfio-pci should be supported. However, when I bring it up, VPP is complaining: EAL: Detected 72 lcore(s) EAL: No free hugepages reported in hugepages-1048576kB EAL: Probing VFIO support...

However I do have those interfaces bound to vfio-pci already, here is the output from dpdk-devbind.py: [root@sjc04-pod6-compute-4 tools]# ./dpdk-devbind.py --status Network devices using DPDK-compatible driver ============================================ 0000:16:00.1 'Ethernet Controller X710 for 10GbE SFP+' drv=vfio-pci unused=i40e 0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+' drv=vfio-pci unused=i40e Do we ever tested vfio-pci on X710 before, or did I miss anything? Appreciate your helps! Thanks very much! Regards, Yichen Have you specified: dpdk { uio-driver vfio-pci } in startup.conf?
