Seeking help to configure DPDK 22 on Ubuntu 22.04.1 - "No probed ethernet devices"

Seeking help to configure DPDK 22 on Ubuntu 22.04.1 - "No probed ethernet devices"

Hi Everyone,

I'm trying to configure DPDK 22 on Ubuntu 22.04.3 LTS and I'm facing an
issue when running the testpmd application.

Whenever I execute:

    sudo ./dpdk-testpmd

I get the following error:

    testpmd: No probed ethernet devices

I've followed the setup steps from the DPDK documentation, including
hugepages allocation and binding NICs with vfio-pci, but still encountering
the same issue.

Could someone please help point out what might be missing or guide me on
how to properly configure DPDK on this version of Ubuntu?

I have tried on both these NICs:
0000:00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection
(17) I219-LM (rev 11)
0000:01:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network
Connection (rev 03)

Thanks in advance for your help!

Best regards,
Aniket Singh

You have to rebind the NIC's to vfio-pci to allow use by DPDK.
Did you look at dpdk-devbind.py script?

Also, some of the on board Ethernet controllers are not yet supported
by DPDK. They fall under the igb driver, but the PCI id's are not listed.
Needs backport from BSD or Linux driver for that.

Hi  Stephen,

I did rebind the NIC's to vfio-pci using the
dpdk-devbind.py script.

Does that mean both the NICs (I219-LM and I1210) are not supported by DPDK?

Thanks,

If your NIC is not part of this, then yes it's NOT SUPPORTED officially.

https://core.dpdk.org/supported/

Use lspci to find the PCI id vendor then look at the source is the
definitive answer.
$ sudo ethtool -i enp87s0
...
bus-info: 0000:57:00.0

$ lspci -s 0000:57:00 -n
57:00.0 0200: 8086:125c (rev 04)

drivers/net $ git grep 125C
intel/e1000/base/e1000_hw.h:#define E1000_DEV_ID_I226_V                 0x125C
 $ git grep ID_I226_V
intel/e1000/base/e1000_api.c:   case E1000_DEV_ID_I226_V:
