[dpdk-users] [SRIOV][TestPMD][OpenStack] No probed ethernet devices

[Rosen, Rami]

Chris,

>(not igb_uio - which I read was deprecated).
Interesting, can you please give a link to where you read it ? 

Do you have "iommu=pt intel_iommu=on" in the kernel command line ? does "cat /proc/cmdline" show it ? 

What does "dmesg | grep -e DMAR -e IOMMU" show ? 

Regards,
Rami Rosen

Hello. I am trying to get testpmd up and running in a RHEL 7.4 guest (DPDK 17.08), however, I am unable to get my interface to bind to a dpdk compatible driver.

[root at localhost ~]# dpdk-devbind --status

Network devices using DPDK-compatible driver ============================================
<none>

Network devices using kernel driver
===================================
0000:00:03.0 'Virtio network device' if=eth0 drv=virtio-pci unused=virtio_pci,vfio-pci *Active*
0000:00:05.0 '82599 Ethernet Controller Virtual Function' if=eth1 drv=ixgbevf unused=vfio-pci *Active*

I am trying to bind the vfio-pci driver (not igb_uio - which I read was deprecated).

I am running into the following error.

[root at testpmd-vm ~]# dpdk_nic_bind --bind=vfio-pci 0000:00:05.0
Error: bind failed for 0000:00:05.0 - Cannot bind to driver vfio-pci

Has anyone seen this before? Can someone confirm that I am attempting to bind correctly?
