How to list PCI devices in Linux - lspci

As FreeBSD, Linux also has an utility to list the pci devices. This is lspci.

NAME
lspci - list all PCI devices

SYNOPSIS
lspci [options]

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

By default, it shows a brief list of devices. Use the options described below to request either a more verbose output or output intended for parsing by other proâ€
grams.

If you are going to report bugs in PCI device drivers or in lspci itself, please include output of "lspci -vvx" or even better "lspci -vvxxx" (however, see below for
possible caveats).

Some parts of the output, especially in the highly verbose modes, are probably intelligible only to experienced PCI hackers. For exact definitions of the fields,
please consult either the PCI specifications or the header.h and /usr/include/linux/pci.h include files.

Access to some parts of the PCI configuration space is restricted to root on many operating systems, so the features of lspci available to normal users are limited.
However, lspci tries its best to display as much as available and mark all other information with <access denied> text.
...
-t Show a tree-like diagram containing all buses, bridges, devices and connections between them.
...
-v Be verbose and display detailed information about all devices.

the "lspci -tv" command lists a linux system's PCI devices in such a way that you can see if, for example, if there are any Network Cards with multple ports and the chipsets they have (as above)
