NAME

       pcilib - a library for accessing PCI devices

DESCRIPTION

       The  PCI library (also known as pcilib and libpci) is a portable library for accessing PCI
       devices and their configuration space.

ACCESS METHODS

       The library supports a variety of methods to access the configuration space  on  different
       operating systems. By default, the first matching method in this list is used, but you can
       specify override the decision (see the -A switch of lspci).

       linux-sysfs
              The /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, VPD (from Linux  2.6.26),  physical  slots  (also  since  Linux
              2.6.26) and information on attached kernel drivers.

       linux-proc
              The  /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.

       intel-conf1
              Direct hardware access via Intel configuration mechanism 1. Available on  i386  and
              compatibles on Linux, Solaris/x86, GNU Hurd, Windows, BeOS and Haiku. Requires root
              privileges.

       intel-conf2
              Direct hardware access via Intel configuration mechanism 2. Available on  i386  and
              compatibles on Linux, Solaris/x86, GNU Hurd, Windows, BeOS and Haiku. Requires root
              privileges. Warning: This method is able to address only the first  16  devices  on
              any bus and it seems to be very unreliable in many cases.

       fbsd-device
              The /dev/pci device on FreeBSD. Requires root privileges.

       aix-device
              Access method used on AIX. Requires root privileges.

       nbsd-libpci
              The /dev/pci0 device on NetBSD accessed using the local libpci library.

       obsd-device
              The /dev/pci device on OpenBSD. Requires root privileges.

       dump   Read the contents of configuration registers from a file specified in the dump.name
              parameter. The format corresponds to the output of lspci -x.

       darwin Access method used on Mac OS X / Darwin. Must be run as root and  the  system  must
              have been booted with debug=0x144.

PARAMETERS

       The library is controlled by several parameters. They should have sensible default values,
       but in case you want to do something unusual (or even something weird), you  can  override
       them (see the -O switch of lspci).

   Parameters of specific access methods
       dump.name
              Name of the bus dump file to read from.

       fbsd.path
              Path to the FreeBSD PCI device.

       nbsd.path
              Path to the NetBSD PCI device.

       obsd.path
              Path to the OpenBSD PCI device.

       proc.path
              Path to the procfs bus tree.

       sysfs.path
              Path to the sysfs device tree.

   Parameters for resolving of ID's via DNS
       net.domain
              DNS domain containing the ID database.

       net.cache_name
              Name of the file used for caching of resolved ID's.

   Parameters for resolving of ID's via UDEV's HWDB
       hwdb.disable
              Disable use of HWDB if set to a non-zero value.
