In Pktgen I just use the normal rte_eth_device_count() (whatever it is call= ed) to find the ports in the system. This means something in that configura= tion is not setup and DPDK is not finding the ports in the system. Has noth= ing to do with Pktgen that I know of, but I have not tried vfio-pci driver = and can not as I am out of town. >=20 > Does anyone have any ideas whats going on here? What is "failed to > select IOMMU type" telling me? For the hard lockup problem try using testpmd application and see if that t= he same problem if not then it will be next week before I can look at. Let me know if testpmd works or not. >=20 > CentOS 7 / Kernel 4.13 / DPDK 17.08 / Pktgen 3.4.2. >=20 > Cheers, > James. >=20 >=20 > $ sudo ./app/x86_64-native-linuxapp-gcc/pktgen -l 2-6 -n 1 -w 09:00.0 > -w 09:00.1 -v -- -P -m [3-4].0 [5-6].1 >=20 > Copyright (c) <2010-2017>, Intel Corporation.
