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
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
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.
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 --classmask mask
--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,

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.
