++.TH pcimodules 8 "@TODAY@" "@VERSION@" "Linux PCI Utilities"
++.IX pcimodules
++.SH NAME
++pcimodules \- List kernel driver modules available for all currently plugged
++in PCI devices
++.SH SYNOPSIS
++.B pcimodules
++.RB [ --class class_id ]
++.RB [ --classmask mask ]
++.RB [ --help ]
++.SH DESCRIPTION
++.B pcimodules
++lists all driver modules for all currently plugged in PCI devices.
++.B pcimodules
++should be run at boot time, and whenever a PCI device is "hot plugged"
++into the system. This can be done by the following Bourne shell syntax:
++.IP
++ for module in $(pcimodules) ; do
++.IP
++ modprobe -s -k "$module"
++.IP
++ done
++.PP
++When a PCI device is removed from the system, the Linux kernel will
++decrement a usage count on PCI driver module. If this count drops
++to zero (i.e., there are no PCI drivers), then the
++.B modprobe -r
++process that is normally configured to run from cron every few minutes
++will eventually remove the unneeded module.
++.PP
++The --class and --classmask arguments can be used to limit the search
++to certain classes of PCI devices. This is useful, for example, to
++generate a list of ethernet card drivers to be loaded when the kernel
++has indicated that it is trying to resolve an unknown network interface.
++.PP
++Modules are listed in the order in which the PCI devices are physically
++arranged so that the computer owner can arrange things like having scsi
++device 0 be on a controller that is not alphabetically the first scsi
++controller.
++.SH OPTIONS
++.TP
++.B --class class --classmask mask
++.PP
++--class and --classmask limit the search to PCI
++cards in particular classes. These arguments are always used together.
++The arguments to --class and --classmask
++can be given as hexadecimal numbers by prefixing a leading "0x".
++Note that the classes used by pcimodules are in "Linux" format,
++meaning the class value that you see with lspci would be shifted
++left eight bits, with the new low eight bits programming interface ID.
++An examples of how to use class and classmask is provided below.
++.B --help, -h
++Print a help message and exit.
++.SH EXAMPLES
++.TP
++pcimodules
++lists all modules corresponding to currently plugged in PCI devices.
++.TP
++pcimodules --class 0x200000 --classmask 0xffff00
++lists all modules corresponding to currently plugged in ethernet PCI devices.
++.SH FILES
++.TP
++.B /lib/modules/<kernel-version>/modules.pcimap
++This file is automatically generated by
++.B depmod,
++and used by
++.B pcimodules
++to determine which modules correspond to which PCI ID's.
++.TP
++.B /proc/bus/pci
++An interface to PCI bus configuration space provided by the post-2.1.82 Linux
++kernels. Contains per-bus subdirectories with per-card config space files and a
++.I devices
++file containing a list of all PCI devices.
