I have several 10G X710 cards on a host, mapped into a kvm-based guest via = PCI-passthrough. DPDK sees these cards (the 6 in "Other Network Devices"): # dpdk-devbind --status Network devices using kernel driver =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 0000:00:03.0 '82540EM Gigabit Ethernet Controller 100e' if=3Deth0 drv=3De10= 00 unused=3Duio_pci_generic 0000:00:04.0 'Virtio network device 1000' if=3Deth1 drv=3Dvirtio-pci unused= =3Duio_pci_generic Other Network devices =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 0000:00:09.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic 0000:00:0a.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic 0000:00:0b.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic 0000:00:0c.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic 0000:00:0d.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic 0000:00:0e.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=3Duio_pc= i_generic No 'Crypto' devices detected =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D No 'Eventdev' devices detected =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D No 'Mempool' devices detected =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D No 'Compress' devices detected =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D But it wont bind them to the i40e driver: root@10.129.182.229:~# dpdk-devbind -b i40e "0000:00:09.0" Error: bind failed for 0000:00:09.0 - Cannot bind to driver i40e I'm wondering what I can do to debug this?
