Hello DPDK community, I met errors when running ip_pipeline and test_ip_pipeline sample application. I'm using dpdk-2.1.0 on ubuntu 14.04 host with kernel 3.16. My host machine has two 10G ports and they are working for l2fwd sample application but not for ip_pipeline, so I'm wondering is there any specific requirement for NIC to run this app? The command I use is: sudo ./build/ip_pipeline -p 0x11.
The error message is as follows: EAL: Ask a virtual area of 0x200000 bytes EAL: Virtual area found at 0x7fb9d8200000 (size = 0x200000) EAL: Requesting 256 pages of size 2MB from socket 0 EAL: Requesting 768 pages of size 2MB from socket 1 EAL: TSC frequency is ~2666753 KHz EAL: Master lcore 0 is ready (tid=74659900;cpuset=[0]) EAL: lcore 1 is ready (tid=d81ff700;cpuset=[1]) EAL: PCI device 0000:05:00.0 on NUMA socket -1 EAL: probe driver: 8086:10c9 rte_igb_pmd EAL: Not managed by a supported kernel driver, skipped EAL: PCI device 0000:05:00.1 on NUMA socket -1 EAL: probe driver: 8086:10c9 rte_igb_pmd EAL: Not managed by a supported kernel driver, skipped EAL: PCI device 0000:07:00.0 on NUMA socket -1 EAL: probe driver: 8086:1572 rte_i40e_pmd EAL: PCI memory mapped at 0x7fb9d71ff000 EAL: PCI memory mapped at 0x7fba7465d000 PMD: eth_i40e_dev_init(): FW 4.22 API 1.2 NVM 04.02.05 eetrack 8000143f PMD: eth_i40e_dev_init(): Failed to stop lldp PMD: i40e_pf_parameter_init(): Max supported VSIs:66 PMD: i40e_pf_parameter_init(): PF queue pairs:64 PMD: i40e_pf_parameter_init(): Max VMDQ VSI num:63 PMD: i40e_pf_parameter_init(): VMDQ queue pairs:4 EAL: PCI device 0000:07:00.1 on NUMA socket -1 EAL: probe driver: 8086:1572 rte_i40e_pmd EAL: PCI memory mapped at 0x7fb9d69ff000 EAL: PCI memory mapped at 0x7fba7461e000 PMD: eth_i40e_dev_init(): FW 4.22 API 1.2 NVM 04.02.05 eetrack 8000143f PMD: eth_i40e_dev_init(): Failed to stop lldp PMD: i40e_pf_parameter_init(): Max supported VSIs:66 PMD: i40e_pf_parameter_init(): PF queue pairs:64 PMD: i40e_pf_parameter_init(): Max VMDQ VSI num:63 PMD: i40e_pf_parameter_init(): VMDQ queue pairs:4 [APP] Initializing MEMPOOL0 ...
