   3 .SH NAME
   4 lspci \- list all PCI devices
   5 .SH SYNOPSIS
   6 .B lspci
   7 .RB [ options ]
   8 .SH DESCRIPTION
   9 .B lspci
  10 is a utility for displaying information about all PCI busses in the system and
  11 all devices connected to them. It requires Linux kernel 2.1.82 or newer and
  12 supersedes the original /proc/pci interface found in earlier kernels.
  13
  14 If you are going to report bugs in PCI device drivers or in
  15 .I lspci
  16 itself, please include output of "lspci -vvx".
  17
  18 .SH OPTIONS
  19 .TP
  20 .B -v
  21 Tells
  22 .I lspci
  23 to be verbose and display detailed information about all devices.
  24 .TP
  25 .B -vv
  26 Tells
  27 .I lspci
  28 to be very verbose and display even more information (actually everything the
  29 PCI device is able to tell). The exact meaning of these data is not explained
  30 in this manual page, if you want to know more, consult
  31 .B /usr/include/linux/pci.h
  32 or the PCI specs.
  33 .TP
  34 .B -n
  35 Show PCI vendor and device codes as numbers instead of looking them up in the
  36 PCI ID database.
  37 .TP
  38 .B -x
  39 Show hexadecimal dump of first 64 bytes of the PCI configuration space (the standard
  40 header). Useful for debugging of drivers and
  41 .I lspci
  42 itself.
  43 .TP
  44 .B -xx
  45 Show hexadecimal dump of whole PCI configuration space. Available only for root
  46 as several PCI devices crash when you try to read undefined portions of the config
  47 space (although this directly violates the PCI standard).
  48 .TP
  49 .B -b
  50 Bus-centric view. Show all IRQ numbers and addresses as seen by the cards on the
  51 PCI bus instead of as seen by the kernel.
  52 .TP
  53 .B -t
  54 Show a tree-like diagram containing all busses, bridges, devices and connections
  55 between them.
  56 .TP
  57 .B -B <bus>
  58 Show only devices on specified bus.
  59 .TP
  60 .B -S <slot>
  61 Show only devices in specified slot number.
  62 .TP
  63 .B -F <func>
  64 Show only specified function number of all devices (you can mix it with
  65 .B -B
  66 and
  67 .B -S
  68 to select single device).
  69 .TP
  70 .B -V <vendor>
  71 Show only devices having specified vendor ID.
  72 .TP
  73 .B -D <devid>
  74 Show only devices having specified device ID.
  75 .TP
  76 .B -i <file>
  77 Use
  78 .B
  79 <file>
  80 as PCI ID database instead of /etc/pci.ids.
  81 .TP
  82 .B -p <dir>
  83 Use
  84 .B <dir>
  85 as directory containing PCI bus information instead of /proc/bus/pci.
  86
  87 .SH FILES
  88 .TP
  89 .B /etc/pci.ids
  90 A list of all known PCI ID's (vendors, devices, classes and subclasses).
  91 .TP
  92 .B /proc/bus/pci
  93 An interface to PCI bus configuration space provided by the kernel. Contains
  94 per-bus subdirectories with per-card config space files and a
  95 .I
  96 devices
  97 file containing a list of all PCI devices.
