Simplified modutils.
|
|
|
|
With this option modprobe does not require modules.dep file
|
|
and does not use /etc/modules.conf file.
|
|
It scans module files in /lib/modules/`uname -r` and
|
|
determines dependencies and module alias names on the fly.
|
|
This may make module loading slower, most notably
|
|
when one needs to load module by alias (this requires
|
|
scanning through module _bodies_).
|
|
|
|
At the first attempt to load a module by alias modprobe
|
|
will try to generate modules.dep.bb file in order to speed up
|
|
future loads by alias. Failure to do so (read-only /lib/modules,
|
|
etc) is not reported, and future modprobes will be slow too.
|
|
|
|
NB: modules.dep.bb file format is not compatible
|
|
with modules.dep file as created/used by standard module tools.
|
|
|
|
Additional module parameters can be stored in
|
|
/etc/modules/$module_name files.
|
|
|
|
Apart from modprobe, other utilities are also provided:
|
|
- insmod is an alias to modprobe
|
|
- rmmod is an alias to modprobe -r
|
|
- depmod generates modules.dep.bb

As of 2008-07, this code is experimental. It is 14kb smaller
|

Say 'y' here to enable support for the 'blacklist' command in

modprobe.conf. This prevents the alias resolver to resolve
