+.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.
