NAME

       pcimodules - List kernel driver modules available for all currently plugged in PCI devices

SYNOPSIS

       pcimodules [--classclass_id] [--classmaskmask] [--help]

DESCRIPTION

       pcimodules  lists  all driver modules for all currently plugged in PCI devices.  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:

                   for module in $(pcimodules) ; do

                        modprobe -s "$module"

                   done

       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 modprobe -r process  that
       is normally configured to run from cron every few minutes will eventually remove the unneeded module.

       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.

       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.

OPTIONS

       --class class --classmask mask

       --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.  --help, -h Print a help
       message and exit.

EXAMPLES

       pcimodules
              lists all modules corresponding to currently plugged in PCI devices.

       pcimodules --class 0x20000 --classmask 0xffff00
              lists all modules corresponding to currently plugged in ethernet PCI devices.

FILES

       /lib/modules/<kernel-version>/modules.pcimap
              This file is automatically generated by depmod, and used by pcimodules to determine which  modules
              correspond to which PCI ID's.

       /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 devices file containing  a  list  of
              all PCI devices.
