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//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.
