Intel Aria 10 PCIe SRIOV design

agula · ‎10-20-2020

Hello All,

I am trying to develop a network acceleration application that needs to support 128 VFs. I'm using an Aria 10 board and have a working PCIe SRIOV design at the hardware level. I can use drivers to enable SRIOV Virtual Functions and can see them by using lpsci -d '1172:'. I would like to connect these Virtual Functions to network interfaces such as eth2 , eth3, eth4 etc. Do I need to manually add these interfaces somehow or should they automatically be recognized ?

Thank you!

Hi Sir,

The VFs will be auto recognized by the system if you set it accordingly in the “SR-IOV System Setting” of the IP GUI.

Hi,
Thanks for your response. Are you referring to platform designer system settings in Quartus, when building the IP system ? Currently the virtual functions are recognized using lspci. What I am interesting in knowing is do we need to develop the network stack drivers ourselves to integrate it into a network application?

Hi Sir,

Yes, it is platform designer system in Quartus.

The host able to recognize the VFs because the FPGA PCIe IP already create the VFs. For sure, you need to develop the custom drivers based on your application needs. You may find the PCIe SR-IOV UG from this links.

Hope this helps.
