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

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

       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 -k "$module"


       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 min-
       utes 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

       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.

       --class class --classmask mask

       --class	and --classmask limit the search to PCI cards in particular classes.  These argu-
       ments 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.

	      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.

	      This file is automatically generated by depmod, and used by pcimodules to determine
	      which modules correspond to which PCI ID's.

	      An  interface to PCI bus configuration space provided by the post-2.1.82 Linux ker-
	      nels. Contains per-bus subdirectories  with  per-card  config  space  files  and	a
	      devices file containing a list of all PCI devices.
