PCIe configuration/capability list

Hi Victor thanks for the reply, I'll add the info you asked for.

What’s exactly this custom hardware card?

It's an FPGA readout card called FELIX used to buffer data for data acquisition for the DUNE experiment.

Are you the developer of this card?

No, I'm not the developer. If you'd like more info you can look up ATLAS FELIX. There's a user manual here for example: https://twiki.nevis.columbia.edu/twiki/pub/ATLAS/SliceTestboard/felix-user-manual.pdf

What is the exact model of the CPUs that you test this card with?

Intel Xeon Gold 6348. It was tested successfully with Intel WolfPass C628 chipset and Xeon Gold 6242 previously I believe.

Is the motherboard used with this card an Intel server board? If yes, please provide the model

Dell poweredge R750 motherboard.

Are contacting Intel on behalf of a company? If yes, please provide as many details as possible about the company that your work for.

This isn't on behalf of a company, I'm a researcher for the experiment.

Have you tested a similar piece of hardware card from any other third-party brand? If yes, did it work?

I'm not sure about this.
