Linux – lspci command to list and find out more information about all PCI devices

Posted on in Categories Howto, Linux, Troubleshooting last updated August 17, 2007

lspci is a command for displaying information about all PCI buses in the system and all devices connected to them.

lspci is useful when you want to diagnose problems or when you want to report bugs related to pci devices.

Report PCI devices bugs

$ lspci -vvx

See how PCI devices connected to PCI bus

With -t option you can see PCI layout in a tree format. You can see exactly all buses, bridges, devices and connections between them on your server/PC PCI bus.
$ lspci -t
Output:

-[00]-+-00.0
      +-02.0
      +-1d.0
      +-1d.1
      +-1d.2
      +-1d.7
      +-1e.0-[01]--+-02.0
      |            +-02.1
      |            \-05.0
      +-1f.0
      +-1f.1
      +-1f.3
      \-1f.5

Please note that your master PCI bus is 00. It is better to use -v option with -t to get detailed information:

$ lspci -tv

  1. Will there be any damage caused to the prod or non production system if we execute lspci -s 0:18.1 -xxx from root user ?

  2. Hi there,
    I want to congratulate you for publishing your work free of charge over the internet, to help biginners like myself.
    I will be grateful to have links to sites or whole notes on sticky bits, and VNC.
    Thank you in advance.
    Felix.

  3. You probably need to edit /etc/udev/rules.d/70-persistent-net.rules so that the ethernet card you want to use is assigned to the ethX device you want it on.
