I am surprised to see you are using a 16.04 version. I recommend using the latest LTS, i.e. 20.11. For this version, the quick start guide is https://doc.dpdk.org/guides-20.11/linux_gsg/index.html > refer to nonexistent SETUP.SH, i walking over the docs an do steps to > unsure that DPDK is working at all after installation. > > So: > > > [root@sysman ~]# sudo modprobe uio_pci_generic > [ 1084.673269] Generic UIO driver for PCI 2.3 devices version: 0.01.0 > > [root@sysman ~]# sudo modprobe vfio-pci > [ 1118.429157] VFIO - User Level meta-driver version: 0.3 > > [root@sysman ~]# dpdk-devbind.py -s > > Network devices using kernel driver > =================================== > 0000:02:01.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' > if=ens33 drv=e1000 unused=vfio-pci,uio_pci_generic *Active* > 0000:02:05.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' > if=ens37 drv=e1000 unused=vfio-pci,uio_pci_generic > 0000:02:06.0 '82545EM Gigabit Ethernet Controller (Copper) 100f' > if=ens38 drv=e1000 unused=vfio-pci,uio_pci_generic > > [root@sysman ~]# dpdk-devbind.py --bind=vfio-pci ens37 > Error: bind failed for 0000:02:05.0 - Cannot bind to driver vfio-pci > Error: unbind failed for 0000:02:05.0 - Cannot open > /sys/bus/pci/drivers//unbind > > [ 1215.157980] vfio-pci: probe of 0000:02:05.0 failed with error -22 > [ 1215.164317] vfio-pci: probe of 0000:02:05.0 failed with error -22 If your server has a iommu, you probably did not configure it. If you don't have such hw, you need no-iommu support. https://doc.dpdk.org/guides-20.11/linux_gsg/linux_drivers.html#troubleshooting-vfio -- David Marchand
