.SH NAME
lspci \- list all PCI devices
.SH SYNOPSIS
.B -D
Always show PCI domain numbers. By default, lspci suppresses them on machines which
have only domain 0.
+.TP
+.B -P
+Identify PCI devices by path through each bridge, instead of by bus number.
+.TP
+.B -PP
+Identify PCI devices by path through each bridge, showing the bus number as
+well as the device number.

-.B -s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]
+.B -s [[[[<domain>]:]<bus>]:][<device>][.[<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).
+of its own; domains are numbered from 0 to ffff), bus (0 to ff), device (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".
+.B -d [<vendor>]:[<device>][:<class>[:<prog-if>]]
+Show only devices with specified vendor, device, class ID, and programming interface.
+The ID's are given in hexadecimal and may be omitted or given as "*", both meaning
+"any value". The class ID can contain "x" characters which stand for "any digit".
.SS Other options
.TP
.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.
+those behind misconfigured bridges, etc. This option gives meaningful results only
+with a direct hardware access mode, which usually requires root privileges.
+By default, the bus mapper scans domain. You can use the
+.B -s
+option to select a different domain.
