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.

In Pktgen I just use the normal rte_eth_device_count() (whatever it is called) to find the ports in the system. This means something in that configuration is not setup and DPDK is not finding the ports in the system. Has nothing to do with Pktgen that I know of, but I have not tried vfio-pci driver and can not as I am out of town.

For the hard lockup problem try using testpmd application and see if that the same problem if not then it will be next week before I can look at.
Let me know if testpmd works or not.

Hi, James,
First I agree with Keith about that this means something in that configuration is not setup correctly
and DPDK is not finding the ports in the system, and has nothing to do with Pktgen.
It seems to me that if you will try to run any application (like testpmd) on this setup you will get the same problem.
Can you please check and confirm ?
Second, I think the root cause for not finding the ports is around this message ("failed to select IOMMU type") in:
...
> EAL: probe driver: 8086:1572 net_i40e
> EAL: 0000:09:00.0 failed to select IOMMU type
> EAL: Requested device 0000:09:00.0 cannot be used
> EAL: PCI device 0000:09:00.1 on NUMA socket 0
> EAL: probe driver: 8086:1572 net_i40e
> EAL: 0000:09:00.1 failed to select IOMMU type
> EAL: Requested device 0000:09:00.1 cannot be used
...
What does " find /sys/kernel/iommu_groups/ -type l"
give ?
Could it be that 0000:09:00.0 and 0000:09:00.1 belongs to an IOMMU group in which there are other devices ?

Rami Rosen

Hi guys,
Thank you all for your responses!
I initially thought this was unlikely to be a Pktgen specific issue
however I thought it worth mentioning I am using Pktgen just in case.

Do you mean upper case "-P"? Lower case “p” isn’t an option in “Pktgen
–-help” output.

Thanks for taking the time to reply whilst traveling Keith!
Sadly I’m getting the same behaviour with testpmd:

To me (a layman) this looks correct, do you agree?

Do you have Intel VT-d enabled in the BIOS and intel_iommu=on iommu=pt in grub?
I have had some issues with enabling this where other devices such as RAID controllers cause the OS to no boot after applying these settings. Removing the grub line and upgrading the RAID firmware fixed the issue.
IOMMU<https://dpdk-guide.gitlab.io/dpdk-guide/setup/iommu.html#iommu>
An input-output memory management unit (IOMMU) is required for safely driving DMA-capable hardware from userspace and because of that it is a prerequisite for using VFIO. Not all systems have one though, so you’ll need to check that the hardware supports it and that it is enabled in the BIOS settings (VT-d or Virtualization Technology for Directed I/Oon Intel systems)
Finally, IOMMU needs to be excplitly enabled in the kernel as well. To do so, pass either intel_iommu=on (for Intel systems) or amd_iommu=on (for AMD systems) added to the kernel command line. In addition it is recommended to use iommu=pt option which improves IO performance for devices in the host.
Once the system boots up, check the contents of /sys/kernel/iommu_groups/ directory. If it is non-empty, you have successfully set up IOMMU.
To permanently add this to the kernel commandline, append it to GRUB_CMDLINE_LINUX in /etc/default/grub and then execute:
# grub2-mkconfig -o /boot/grub2/grub.cfg

Hi All,
I have Pktgen working on this box now.
So for the sake of this list archives:
In addition to the 2x10G Intel X710 NIC there is a 2x1G Intel I350 NIC
in this box. Trying with the igb_uio or vfio-pci driver for the 1G NIC
had the same results as with the 10G NIC; hard lock-up when using
igb_uio and DPDK is reporting no free ports available when using
vfio-pci.
However with vfio-pci the following syslog message was logged:
"Device is ineligible for IOMMU domain attach due to platform RMRR
requirement. Contact your platform vendor."
After some searching this seems to be an issue with Kernels newer than
3.16 on HPE boxes (e.g.
https://forums.lime-technology.com/topic/53049-solved-device-is-ineligible-for-iommu-domain-attach-due-to-platform-rmrr/).
Looks like a BIOS setting can solve this issue
(https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c04781229&sp4ts.oid=5249566).
I have multiple Kernels compiled on this box. I was using 4.13 for
some other testing, so I booted into 3.10, recompiled DPDK+Pktgen and
both the 10G and 1G NICs are working using the igb_uio driver.
I'd like to be a 4.10 kernel as I was testing some features in there
separate to DPDK so I will try disabling that BIOS setting and see if
this works with the newer Kernel version. The box is remote so I can't
do that right away!
Many thanks all for your time and help it is greatly appreciated.
Cheers,
James.
