Hi All, I have some HPE DL boxes that use "HP" NICs (OEM Intel X710s). I have compiled DPDK & Pktgen but when I try to run Pktgen the box hard crashes (it locks up and I have bounce it using IPMI).
The main output is below although a full transcript of my attempt is here: https://null.53bits.co.uk/uploads/linux/applications/dpdk/CentOS-DL120-DPDK-NIC-Bind.txt Essentially I can bind the NICs to DPDK using the igb_uio driver, which leads to the hard crash, or I can bind the NICs to DPDK using the vfio-pci driver but then Pktgen reports that there are no NICs available to use and exits. Does anyone have any ideas whats going on here? What is "failed to select IOMMU type" telling me? CentOS 7 / Kernel 4.13 / DPDK 17.08 / Pktgen 3.4.2. Cheers, James. $ 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 Copyright (c) <2010-2017>, Intel Corporation. All rights reserved.
