Config request TLPs

Postby Guest » Tue Mar 03, 2020 12:15 am

Hi Eli,

Thanks a lot for your post on TLP. I think I get most of the information you shared, I have an FPGA and I am able to craft TLP for memory transactions (DMA) that actually work. I tried to do he same for IO and Config (ID routing) and I keep getting unsupported command on the completion. Do you have a practical example of Config TLP sent by a PCIe device?

I am trying to check if a device is capable of sending Config request to another device, just for curiosity.

Thanks a lot!

Unfortunately, no, I never had any need to deal with config or I/O.
