For now, you have to look at PCI ids. NVIDIA GPUs have "10de:xxxx"
as vendor/device ids, that's what is shown in your boxes on the
We should have better GPU support in the future. Right now, we only
use what Linux knows, and it knows pretty much nothing about NVIDIA
GPUs because of the closed-source driver :/

Dear hwloc user,
I'm using hwloc 1.5. I would to see how GPUs are connected
with the processor socket using lstopo command.
I attach the figure. The system has two GPUs, but I don't
understand how to find that information from PCI boxes.
Thanks in advance.
