       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  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

       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


       --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.

       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

              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.
