Hi all,
I'm setting DPDK on our hardware to do some experiment, but suffering from .

I was trying to use DPDK on Ubuntu 18.04 with Intel XL710 Ethernet Adapter
with igb_uio driver. I've compiled DPDK from source, and bound the driver
to NIC.
But when I run `testpmd` application, it returns an error like this.

```
$ sudo ./build/app/testpmd

```
I tried to find what return code -66 from adminq means, but I couldn't find
it.
Some say this might have to do with Intel IOMMU pass-through, but I'm not
sure that's the case.

Has anyone had this issue before? Maybe some tip on this issue would be
very helpful.

Thank you,
Sunghyuk

Hi,
Thanks for the solution.

Actually, I was trying with igb_uio driver, rather than vfio-pci.
Would that make a difference?

Thank you,
Sunghyuk

Hi,

If you want to use igb_uio instead of vfio-pci, then you have to make the
following changes in the GRUB
GRUB_CMDLINE_LINUX="iommu=pt, intel_iommu=on"

update grub settings and reboot the machine.

When we are running DPDK on virtual functions, then it is recommended to
use vfio-pci instead of igb_uio.
You can refer this link
http://mails.dpdk.org/archives/dev/2014-August/004610.html for more details.

Dheeraj Dang

Hi, sorry for the late reply.

I had done more digging on the message, and I guess the issue was because
of NIC's low firmware version.
(I found IO_PAGE_FAULT on dmesg)

Since I didn't want to screw up with the current environment (including
firmware), I managed to run DPDK on other hardware with your advice on GRUB
settings, so I might be able to see what my real problem was later in the
future :)

Thanks for the kind response.

Regards,
Sunghyuk
