Hi, Below is my configuration:
AOC: Mellanox MT27500 Family [ConnectX-3] OS: Ubuntu 16.04 DPDK version: 17.05.1 Pktgen: 3.3.8 Memory: 16G CPU: Intel(R) Xeon(R) CPU D-1557 (12C) I've enabled the configuration in dpdk (CONFIG_RTE_LIBRTE_MLX4_PMD=y) and installed Mellanox OFED <http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers> driver and recompiled DPDK. It all worked. Below is my pci network class information: pci@0000:03:00.0 eno3 network Ethernet Connection X552/X557-AT 10GBAS pci@0000:03:00.1 eno4 network Ethernet Connection X552/X557-AT 10GBAS pci@0000:04:00.0 ib0 network MT27500 Family [ConnectX-3] pci@0000:05:00.0 eno1 network I350 Gigabit Network Connection pci@0000:05:00.1 eno2 network I350 Gigabit Network Connection pci@0000:04:00.0 ens2d1 network Ethernet interface And my step to run pktgen is shown in the following: $test: modprobe -a ib_uverbs mlx4_en mlx4_core mlx4_ib $test: /etc/init.d/openibd restart $test: sudo ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-6 -n 1 --proc-type auto --file-prefix pg -b 03:00.0 -b 03:00.1 -b 05:00.0 -b 05:00.1 -- -P -m "[1-5.0]" Looks like in order to use mlx4, i need to blacklist other ports so that i -b other ports. However, when i run the command above to execute pktgen, i got the following error: >>> Packet Burst 32, RX Desc 512, TX Desc 1024, mbufs/port 8192, mbuf cache 1024 !PANIC!: *** Did not find any ports to use *** PANIC in pktgen_config_ports(): *** Did not find any ports to use ***6: [./app/x86_64-native-linuxapp-gcc/pktgen(_start+0x29) [0x447239]] 5: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7f0ec0931830]] 4: [./app/x86_64-native-linuxapp-gcc/pktgen(main+0x580) [0x444710]] 3: [./app/x86_64-native-linuxapp-gcc/pktgen(pktgen_config_ports+0x1614) [0x46e324]] 2: [./app/x86_64-native-linuxapp-gcc/pktgen(__rte_panic+0xc3) [0x43ead4]] 1: [./app/x86_64-native-linuxapp-gcc/pktgen(rte_dump_stack+0x2b) [0x4b7ecb]] Aborted (core dumped) Anyone might have related experience please provide advise.
