How do i display tree like diagram of my pci devices?

  • 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

    Particularly use in combination with the -v option.

    $ lspci -tv
