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 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 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.
