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