- modprobe can indirectly benefit from FEATURE_2_4_MODULES and FEATURE_INSMOD_TRY_MAP options. - The position of config FEATURE_INSMOD_TRY_MMAP prevented some other config options from indenting under FEATURE_2_4_MODULES. Reorder to fix this. - FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED is now moved to Config.src under "Common options" section. (I wished to edit this config so that it also work with "big" modutils, but it's not done at the moment. Sorry.)

config MODPROBE_SMALL

help
|
|
Build smaller (~1.5 kbytes), simplified module tools.
|
|
|
|
This option by itself does not enable any applets -
|
|
you need to select applets individually below.
|
|
|
|
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.

By adding module symbols to the kernel symbol table, Oops messages

occuring within kernel modules can be properly debugged. By enabling

this feature, module symbols will always be added to the kernel symbol

help
|

This is a special uClinux only memory optimization that lets insmod
|

load the specified kernel module directly into kernel space, reducing

memory usage by preventing the need for two copies of the module

being loaded into memory.

Enabling this, one would be able to get a load map

Support checking for tainted modules. These are usually binary

bool "Try to load module from a mmap'ed area"

default n

depends on (INSMOD || MODPROBE) && !MODPROBE_SMALL
|
|
help
|
|
This option causes module loading code to try to mmap
|
|
module first. If it does not work (for example,
|
|
it does not work for compressed modules), module will be read
|
|
(and unpacked if needed) into a memory block allocated by malloc.
|
|
|
|
The only case when mmap works but malloc does not is when
|
|
you are trying to load a big module on a very memory-constrained
|
|
machine. Malloc will momentarily need 2x as much memory as mmap.
|
|
|
|
Choosing N saves about 250 bytes of code (on 32-bit x86).

"modules.dep.bb.bb" or such.
