10config BUSYBOX_CONFIG_MODINFO
11        bool "modinfo"
12        default n
13        help

16config BUSYBOX_CONFIG_MODPROBE_SMALL

20          Simplified modutils.
21
22          With this option modprobe does not require modules.dep file
23          and does not use /etc/modules.conf file.
24          It scans module files in /lib/modules/`uname -r` and
25          determines dependencies and module alias names on the fly.
26          This may make module loading slower, most notably
27          when one needs to load module by alias (this requires
28          scanning through module _bodies_).
29
30          At the first attempt to load a module by alias modprobe
31          will try to generate modules.dep.bb file in order to speed up
32          future loads by alias. Failure to do so (read-only /lib/modules,
33          etc) is not reported, and future modprobes will be slow too.
34
35          NB: modules.dep.bb file format is not compatible
36          with modules.dep file as created/used by standard module tools.
37
38          Additional module parameters can be stored in
39          /etc/modules/$module_name files.
40
41          Apart from modprobe, other utilities are also provided:
42          - insmod is an alias to modprobe
43          - rmmod is an alias to modprobe -r
44          - depmod generates modules.dep.bb
45
46          As of 2008-07, this code is experimental. It is 14kb smaller
47          than "non-small" modutils.

105        help
106          Say 'y' here to enable support for the 'blacklist' command in
107          modprobe.conf. This prevents the alias resolver to resolve
108          blacklisted modules. This is useful if you want to prevent your
109          hardware autodetection scripts to load modules like evdev, frame
110          buffer drivers etc.

135        depends on BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_MODPROBE_SMALL
136        help
137          This option causes module loading code to try to mmap
138          module first. If it does not work (for example,
139          it does not work for compressed modules), module will be read
140          (and unpacked if needed) into a memory block allocated by malloc.
141
142          The only case when mmap works but malloc does not is when
143          you are trying to load a big module on a very memory-constrained
144          machine. Malloc will momentarily need 2x as much memory as mmap.
145
146          Choosing N saves about 250 bytes of code (on 32-bit x86).

160        help
161          By adding module symbols to the kernel symbol table, Oops messages
162          occuring within kernel modules can be properly debugged. By enabling
163          this feature, module symbols will always be added to the kernel symbol
164          table for proper debugging support. If you are not interested in
165          Oops messages from kernel modules, say N.

171        help
172          This is a special uClinux only memory optimization that lets insmod
173          load the specified kernel module directly into kernel space, reducing
174          memory usage by preventing the need for two copies of the module

182          Enabling this, one would be able to get a load map
183          output on stdout. This makes kernel module debugging
184          easier.
185          If you don't plan to debug kernel modules, you
186          don't need this option.
