| 12 | help |
| 13 | Build smaller (~1.5 kbytes), simplified module tools. |
| 14 | |
| 15 | This option by itself does not enable any applets - |
| 16 | you need to select applets individually below. |
| 17 | |
| 18 | With this option modprobe does not require modules.dep file |
| 19 | and does not use /etc/modules.conf file. |
| 20 | It scans module files in /lib/modules/`uname -r` and |
| 21 | determines dependencies and module alias names on the fly. |
| 22 | This may make module loading slower, most notably |
| 23 | when one needs to load module by alias (this requires |
| 24 | scanning through module _bodies_). |
| 25 | |
| 26 | At the first attempt to load a module by alias modprobe |
| 27 | will try to generate modules.dep.bb file in order to speed up |
| 28 | future loads by alias. Failure to do so (read-only /lib/modules, |
| 29 | etc) is not reported, and future modprobes will be slow too. |
| 30 | |
| 31 | NB: modules.dep.bb file format is not compatible |
| 32 | with modules.dep file as created/used by standard module tools. |
| 33 | |
| 34 | Additional module parameters can be stored in |
| 35 | /etc/modules/$module_name files. |

| 80 | Say 'y' here to enable support for the 'blacklist' command in |
| 81 | modprobe.conf. This prevents the alias resolver to resolve |
| 82 | blacklisted modules. This is useful if you want to prevent your |

| 181 | This option causes module loading code to try to mmap |
| 182 | module first. If it does not work (for example, |
| 183 | it does not work for compressed modules), module will be read |
| 184 | (and unpacked if needed) into a memory block allocated by malloc. |
| 185 | |
| 186 | The only case when mmap works but malloc does not is when |
| 187 | you are trying to load a big module on a very memory-constrained |
| 188 | machine. Malloc will momentarily need 2x as much memory as mmap. |
