Thanks Mary,

Hi, All - Regarding 2] igb_uio

I found the igb_uio kernel module at the below location which doesn’t seem to be loaded by default.

controller-0:/lib/modules# find . -name *.ko |grep igb

./4.18.0-147.3.1.rt24.96.el8_1.tis.8.x86_64/extra/igb_uio/igb_uio.ko

Is there any other reason why it isn’t loaded by default?. Is this the target module to be loaded to work with igb_uio ?

Regards,

Venkata Veldanda

Hi Venkata,

Regarding 1]

The StarlingX docs team is upstreaming content at the moment. There is more N3000 FPGA info in the Node Management guide: https://docs.starlingx.io/node_management/index.html

Please see these specific sections:

https://docs.starlingx.io/node_management/starlingx-kubernetes/hardware_acceleration_devices/n3000-overview.html

https://docs.starlingx.io/node_management/starlingx-kubernetes/hardware_acceleration_devices/updating-an-intel-n3000-fpga-image.html

I hope this is helpful.

thanks,

Mary Camp

Subject: [Starlingx-discuss] Intel N3000 FPGA & support for igb_uio module

Hi Team,

1]

I am using StarlingX 4.0 and trying to use the below guide to setup N3000 Vista Creek FPGA card.

https://docs.starlingx.io/configuration/intel_n3000_fpga.html

~(keystone_admin)$ system device-image-upload imagefile root-key pci_vendor

pci_device --key-signature key_signature --name imagename --description

description --image-version version

As part of my N3000 package I see some set of installer images, NVM package updates, iavf driver packages etc. However I am looking for the specific parameters that are highlighted above but I don’t find. Anyone has an idea what does the file name look like for the root-key or the key_signature?

On my baremetal (CentOS vanilla) installation I was following the standard procedure defined “https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-ias-n3000.pdf” but there I didn’t have to use any such key etc. Any help would be appreciated.

2]

Secondly, in StarlingX 4.0 I don’t find igb_uio module present on the host. Is it currently supported as part of stx 4.0?

controller-0:~$ lsmod |grep igb_uio

controller-0:~$

Per documentation I see the below

The supported VF driver(s) are currently:

- igb_uio

- vfio
