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
itself, please include output of "lspci -vvx" or even better "lspci -vvxxx"
(however, see below for possible caveats).

.TP
.B -v
Be verbose and display detailed information about all devices.
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 -k
+Show kernel drivers handling each device and also kernel modules capable of handling it.

+.B -v
+is given in the normal mode of output.
+(Currently works only on Linux with kernel 2.6 or newer.)
+.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 -n
Show PCI vendor and device codes as numbers instead of looking them up in the
PCI ID list.
.B -Q
Query the central database even for entries which are recognized locally.
Use this if you suspect that the displayed entry is wrong.

.TP
.B -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]
Show only devices in the specified domain (in case your machine has several host bridges,
.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
.RI /lib/modules/ kernel_version /modules.pcimap.
Applies only to Linux systems with recent enough module tools.

.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

-the results are identical to normal listing modes, modulo bugs in lspci). Please note

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:

+.SS PCI access options
+.PP
+The PCI utilities use the PCI library to talk to PCI devices (see
+\fBpcilib\fP(7) for details). You can use the following options to
+influence its behavior:
.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, PCI domains
-and information on attached kernel drivers.
-.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 obsd_device
-The
-.B /dev/pci
-device on OpenBSD. Requires root privileges.
-.TP
-.B nbsd_libpci
-The
-.B /dev/pci0
-device on NetBSD accessed using the local libpci library.
-.TP
-.B aix_device
-Access method used on AIX. Requires root privileges.
-
-.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:
-
+.B -A <method>
+The library supports a variety of methods to access the PCI hardware.
+By default, it uses the first access method available, but you can use
+this option to override this decision. See \fB-A help\fP for a list of
+available methods and their descriptions.
.TP
-.B -P <dir>
-Force use of the linux_proc access method, using
-.B <dir>
-instead of /proc/bus/pci.
+.B -O <param>=<value>
+The behavior of the library is controlled by several named parameters.
+This option allows to set the value of any of the parameters. Use \fB-O help\fP
+for a list of known parameters and their default values.
.TP
.B -H1
Use direct hardware access via Intel configuration mechanism 1.
+(This is a shorthand for \fB-A intel-conf1\fP.)
.TP
.B -H2
Use direct hardware access via Intel configuration mechanism 2.
+(This is a shorthand for \fB-A intel-conf2\fP.)
.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
+Instead of accessing real hardware, read the list of devices and values of their
+configuration registers from the given file produced by an earlier run of lspci -x.

.B Rev

.B ~/.pciids-cache
All ID's found in the DNS query mode are cached in this file.
-.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
