Hello, I have a CentOS 7 system with two 2-port X710 cards:
> [root@dhcp13-55 pain]# lspci -nn | grep X710 > 04:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller > X710 for 10GbE SFP+ [8086:1572] (rev 01) > 04:00.1 Ethernet controller [0200]: Intel Corporation Ethernet Controller > X710 for 10GbE SFP+ [8086:1572] (rev 01) > 05:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller > X710 for 10GbE SFP+ [8086:1572] (rev 01) > 05:00.1 Ethernet controller [0200]: Intel Corporation Ethernet Controller > X710 for 10GbE SFP+ [8086:1572] (rev 01) > [root@dhcp13-55 pain]# lib/dpdk/dpdk-17.05.1/usertools/dpdk-devbind.py > --status > > Network devices using DPDK-compatible driver > ============================================ > 0000:04:00.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=igb_uio > unused= > 0000:04:00.1 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=igb_uio > unused= > 0000:05:00.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=igb_uio > unused= > 0000:05:00.1 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=igb_uio > unused= According to tth 17.05 release notes, the cards should work. However, when I run the dpdk_init(), cards are not identified, and rte_eth_dev_count() returns 0. Do you have any idea, what may be the cause or how should I proceed to debug it? Thank you, Martin
