Is there a way to view the link status or other information that would give information on the overall status of the connection of a Linux host in endpoint mode?
To clarify, I have a Jetson set to be the endpoint, this is confirmed to be working by using lspci in another Jetson as root port and am able to transfer data. The next step is to connect an FPGA in root port mode to the endpoint Jetson. I need a way, from the Linux endpoint side, to check that a link and/or communication has been established to the FPGA.
I have looked in dmesg and kern.log and all the various entries in /sys and couldn't find anything that gives the info I'm looking for. Something like lspci but for the endpoint side would be ideal.
