   2 .SH NAME
   3 pcilib \- a library for accessing PCI devices
   4
   5 .SH DESCRIPTION
   6
   7 The PCI library (also known as \fIpcilib\fP and \fIlibpci\fP) is a portable library
   8 for accessing PCI devices and their configuration space.
   9
  10 .SH ACCESS METHODS
  11
  12 .PP
  13 The library supports a variety of methods to access the configuration space
  14 on different operating systems. By default, the first matching method in this
  15 list is used, but you can specify override the decision (see the \fB-A\fP switch
  16 of \fIlspci\fP).
  17
  18 .TP
  19 .B linux-sysfs
  20 The
  21 .B /sys
  22 filesystem on Linux 2.6 and newer. The standard header of the config space is available
  23 to all users, the rest only to root. Supports extended configuration space, PCI domains,
  24 VPD (from Linux 2.6.26), physical slots (also since Linux 2.6.26) and information on attached
  25 kernel drivers.
  26 .TP
  27 .B linux-proc
  28 The
  29 .B /proc/bus/pci
  30 interface supported by Linux 2.1 and newer. The standard header of the config space is available
  31 to all users, the rest only to root.
  32 .TP
  33 .B intel-conf1
  34 Direct hardware access via Intel configuration mechanism 1. Available on i386 and compatibles
  35 on Linux, Solaris/x86, GNU Hurd, Windows, BeOS and Haiku. Requires root privileges.
  36 .TP
  37 .B intel-conf2
  38 Direct hardware access via Intel configuration mechanism 2. Available on i386 and compatibles
  39 on Linux, Solaris/x86, GNU Hurd, Windows, BeOS and Haiku. Requires root privileges. Warning: This method
  40 is able to address only the first 16 devices on any bus and it seems to be very
  41 unreliable in many cases.
  42 .TP
  43 .B fbsd-device
  44 The
  45 .B /dev/pci
  46 device on FreeBSD. Requires root privileges.
  47 .TP
  48 .B aix-device
  49 Access method used on AIX. Requires root privileges.
  50 .TP
  51 .B nbsd-libpci
  52 The
  53 .B /dev/pci0
  54 device on NetBSD accessed using the local libpci library.
  55 .TP
  56 .B obsd-device
  57 The
  58 .B /dev/pci
  59 device on OpenBSD. Requires root privileges.
  60 .TP
  61 .B dump
  62 Read the contents of configuration registers from a file specified in the
  63 .B dump.name
  64 parameter. The format corresponds to the output of \fIlspci\fP \fB-x\fP.
  65 .TP
  66 .B darwin
  67 Access method used on Mac OS X / Darwin. Must be run as root and the system
  68 must have been booted with debug=0x144.
  69
  70 .SH PARAMETERS
  71
  72 .PP
  73 The library is controlled by several parameters. They should have sensible default
  74 values, but in case you want to do something unusual (or even something weird),
  75 you can override them (see the \fB-O\fP switch of \fIlspci\fP).
  76
  77 .SS Parameters of specific access methods
  78
  79 .TP
  80 .B dump.name
  81 Name of the bus dump file to read from.
  82 .TP
  83 .B fbsd.path
  84 Path to the FreeBSD PCI device.
  85 .TP
  86 .B nbsd.path
  87 Path to the NetBSD PCI device.
  88 .TP
  89 .B obsd.path
  90 Path to the OpenBSD PCI device.
  91 .TP
  92 .B proc.path
  93 Path to the procfs bus tree.
  94 .TP
  95 .B sysfs.path
  96 Path to the sysfs device tree.
  97
  98 .SS Parameters for resolving of ID's via DNS
  99 .TP
 100 .B net.domain
 101 DNS domain containing the ID database.
 102 .TP
 103 .B net.cache_name
 104 Name of the file used for caching of resolved ID's.
 105
 106 .SS Parameters for resolving of ID's via UDEV's HWDB
 107 .TP
 108 .B hwdb.disable
 109 Disable use of HWDB if set to a non-zero value.
