Man page for lspci.

This is useful to get a quick mental image of your PCI buses and devices. Physical machine view will be different from virtual machine view.

       -t     Show a tree-like diagram containing all buses, bridges, devices and connections between them.

$ lspci -t
-[0000:00]-+-00.0
           +-01.0
           +-01.1
           +-01.3
           +-02.0
           \-03.0

Particularly use in combination with the -v option.
