Hi, I'm very new to dpdk and I'm trying to set it up on a cluster with the following configuration: DPDK - 16.07 Intel X710 2x10G Nics Ubuntu 15.04
I could compile it, but when running sample applications such as skeleton/basicfwd and testpmd, it fails saying the ports aren't detected. I have done the following: enabled 1G huge pages and mounted them under /dev/hugepages ran dpdk-devbind.py on the interfaces after which the status shows: Network devices using DPDK-compatible driver ============================================ 0000:04:00.0 'Ethernet Controller X710 for 10GbE SFP+' drv=igb_uio unused= 0000:04:00.1 'Ethernet Controller X710 for 10GbE SFP+' drv=igb_uio unused= While running gdb over the basicfwd application (run as sudo as it seemed like a requirement), it seems like rte_eth_dev_count is returning 0. Even the testpmd application is reporting no ports available. I have tried the portmask option and tried to pass the interfaces as -w arguments too. When I looked at rte_eth_dev_count, it's returning an unsigned static int that is only updated by rte_eth_dev_allocate. Following the breadcrumbs, it seemed like someone needed to invoke rte_eth_dev_register. I didn't see that being called in the basicfwd example's codepath. Can anyone tell me what usually causes rte_eth_dev_register to run and update the port number? Or is there anything I might have missed in the configuration that's causing the device to not show up when the library is looking for it.
