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 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 and Windows. Requires root privileges.

       intel-conf2
              Direct hardware access  via  Intel  configuration  mechanism  2.
              Available  on  i386  and  compatibles on Linux, Solaris/x86, GNU
              Hurd and Windows. 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.

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 IDs via DNS
       net.domain
              DNS domain containing the ID database.

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