 .IX lspci
 .SH NAME
 lspci \- list all PCI devices
 .SH SYNOPSIS
 .B lspci
 .RB [ options ]
 .SH DESCRIPTION
 .B lspci
 is a utility for displaying information about all PCI buses in the system and
 all 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 programs.

 If you are going to report bugs in PCI device drivers or in
 .I 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, is probably
 intelligible only to experienced PCI hackers. For the exact definitions of
 the fields, please consult either the PCI specifications or the
 .B header.h
 and
 .B /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
 .I lspci
 available to normal users are limited. However,
 .I lspci
 tries its best to display as much as available and mark all other
 information with
 .I <access denied>
 text.

 .SH OPTIONS
 .TP
 .B -v
 Be verbose and display detailed information about all devices.
 .TP
 .B -vv
 Be very verbose and display more details. This level includes everything deemed
 useful.
 .TP
 .B -vvv
 Be even more verbose and display everything we are able to parse,
 even if it doesn't look interesting at all (e.g., undefined memory regions).
 .TP
 .B -n
 Show PCI vendor and device codes as numbers instead of looking them up in the
 PCI ID list.
 .TP
 .B -x
 Show hexadecimal dump of the standard part of the configuration space (the first
 64 bytes or 128 bytes for CardBus bridges).
 .TP
 .B -xxx
 Show hexadecimal dump of the whole PCI configuration space. It is available only to root
 as several PCI devices
 .B crash
 when you try to read some parts of the config space (this behavior probably
 doesn't violate the PCI standard, but it's at least very stupid). However, such
 devices are rare, so you needn't worry much.
 .TP
 .B -xxxx
 Show hexadecimal dump of the extended (4096-byte) PCI configuration space available
 on PCI-X 2.0 and PCI Express buses.
 .TP
 .B -b
 Bus-centric view. Show all IRQ numbers and addresses as seen by the cards on the
 PCI bus instead of as seen by the kernel.
 .TP
 .B -t
 Show a tree-like diagram containing all buses, bridges, devices and connections
 between them.
 .TP
 .B -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]
 Show only devices in the specified domain (in case your machine has several host bridges,
 they can either share a common bus number space or each of them can address a PCI domain
 of its own; domains are numbered from 0 to ffff), bus (0 to ff), slot (0 to 1f) and function (0 to 7).
 Each component of the device address can be omitted or set to "*", both meaning "any value". All numbers are
 hexadecimal.  E.g., "0:" means all devices on bus 0, "0" means all functions of device 0
 on any bus, "0.3" selects third function of device 0 on all buses and ".4" shows only
 the fourth function of each device.
 .TP
 .B -d [<vendor>]:[<device>]
 Show only devices with specified vendor and device ID. Both ID's are given in
 hexadecimal and may be omitted or given as "*", both meaning "any value".
 .TP
 .B -i <file>
 Use
 .B
 <file>
 as the PCI ID list instead of @IDSDIR@/pci.ids.
 .TP
 .B -m
 Dump PCI device data in machine readable form (both normal and verbose format supported)
 for easy parsing by scripts.
 .TP
 .B -M
 Invoke bus mapping mode which performs a thorough scan of all PCI devices, including
 those behind misconfigured bridges etc. This option is available only to root and it
 gives meaningful results only if combined with direct hardware access mode (otherwise
 the results are identical to normal listing modes, modulo bugs in lspci). Please note
 that the bus mapper doesn't support PCI domains and scans only domain 0.
 .TP
 .B --version
 Shows
 .I lspci
 version. This option should be used stand-alone.

 .SH PCILIB AND ITS OPTIONS
 The PCI utilities use PCILIB (a portable library providing platform-independent
 functions for PCI configuration space access) to talk to the PCI cards. It supports
 the following access methods:

 .TP
 .B linux_sysfs
 The
 .B /sys
 filesystem on Linux 2.6 and newer. The standard header of the config space is available
 to all users, the rest only to root. Supports extended configuration space and PCI domains.
 .TP
 .B linux_proc
 The
 .B /proc/bus/pci
 interface supported by Linux 2.1 and newer. The standard header of the config space is available
 to all users, the rest only to root.
 .TP
 .B intel_conf1
 Direct hardware access via Intel configuration mechanism 1. Available on i386 and compatibles
 on Linux, Solaris/x86, GNU Hurd and Windows. Requires root privileges.
 .TP
 .B intel_conf2
 Direct hardware access via Intel configuration mechanism 2. Available on i386 and compatibles
 on Linux, Solaris/x86 and GNU Hurd. Requires root privileges. Warning: This method
 is able to address only first 16 devices on any bus and it seems to be very
 unreliable in many cases.
 .TP
 .B fbsd_device
 The
 .B /dev/pci
 device on FreeBSD. Requires root privileges.
 .TP
 .B aix_device
 Access method used on AIX. Requires root privileges.
 .TP
 .B nbsd_libpci
 The
 .B /dev/pci0
 device on NetBSD accessed using the local libpci library.

 .P
 By default, PCILIB uses the first available access method and displays no debugging
 messages, but you can use the following switches to control its behavior:

 .TP
 .B -P <dir>
 Force use of the linux_proc access method, using
 .B <dir>
 instead of /proc/bus/pci.
 .TP
 .B -H1
 Use direct hardware access via Intel configuration mechanism 1.
 .TP
 .B -H2
 Use direct hardware access via Intel configuration mechanism 2.
 .TP
 .B -F <file>
 Extract all information from given file containing output of lspci -x. This is very
 useful for analysis of user-supplied bug reports, because you can display the
 hardware configuration in any way you want without disturbing the user with
 requests for more dumps.
 .TP
 .B -G
 Increase debug level of the library.

 .SH FILES
 .TP
 .B @IDSDIR@/pci.ids
 A list of all known PCI ID's (vendors, devices, classes and subclasses). Maintained
 at http://pciids.sourceforge.net/, use the
 .B update-pciids
 utility to download the most recent version.
 .TP
 .B /proc/bus/pci
 An interface to PCI bus configuration space provided by the post-2.1.82 Linux
 kernels. Contains per-bus subdirectories with per-card config space files and a
 .I devices
 file containing a list of all PCI devices.
