| bool "Simplified modutils" |
| default n |
| help |
| 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 |
| than "non-small" modutils. |

| config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE |
| bool "Accept module options on modprobe command line" |
| default n |
| depends on MODPROBE_SMALL |
| help |
| Allow insmod and modprobe take module options from command line. |
| N.B. Very bloaty. |
| |
| config FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED |
| bool "Skip loading of already loaded modules" |
| default n |
| depends on MODPROBE_SMALL |
| help |
| Check if the module is already loaded. |
| N.B. It's racy. |
| |
| config FEATURE_MODPROBE_SMALL_ZIPPED |
| bool "Handle gzipped or bzipped modules" |
| default n |
| depends on MODPROBE_SMALL |

| Handle compressed modules. Bloaty. Sloooow. |

| config DEPMOD |

| depmod generates modules.dep (FIXME: elaborate) |
| |
| config FEATURE_DEPMOD_PRUNE_FANCY |
| bool "Fancy dependency pruning" |
| default n |
| depends on DEPMOD |
| help |
| By default modules.dep contains all dependencies as listed by |
| the modules. |
| If you enable this option then we remove implied modules from |
| the dependencies. |
| This makes depmod somewhat bigger but generates a smaller |
| modules.dep file. |
| |
| If unsure, say N. |
| |
| config FEATURE_DEPMOD_ALIAS |
| bool "Alias support" |
| default n |
| depends on DEPMOD |
| help |
| By default modules.dep does not contain alias information. |
| Enable this to emit aliases of the form: |
| |
| alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs |
| |
| config INSMOD |

| config FEATURE_INSMOD_VERSION_CHECKING |
| bool "Module version checking" |
| default n |
| depends on INSMOD && FEATURE_2_4_MODULES |
| help |
| Support checking of versions for modules. This is used to |
| ensure that the kernel and module are made for each other. |
| |
| config FEATURE_INSMOD_KSYMOOPS_SYMBOLS |
| bool "Add module symbols to kernel symbol table" |
| default n |
| depends on INSMOD && FEATURE_2_4_MODULES |
| help |
| 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 |
| table for properly debugging support. If you are not interested in |
| Oops messages from kernel modules, say N. |
| |
| config FEATURE_INSMOD_LOADINKMEM |
| bool "In kernel memory optimization (uClinux only)" |
| default n |
| depends on INSMOD && FEATURE_2_4_MODULES |
| 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. |
| |
| config FEATURE_INSMOD_LOAD_MAP |
| bool "Enable load map (-m) option" |
| default n |
| depends on INSMOD && ( FEATURE_2_4_MODULES || FEATURE_2_6_MODULES ) |
| help |
| Enabling this, one would be able to get a load map |
| output on stdout. This makes kernel module debugging |
| easier. |
| If you don't plan to debug kernel modules, you |
| don't need this option. |
| |
| config FEATURE_INSMOD_LOAD_MAP_FULL |
| bool "Symbols in load map" |
| default y |
| depends on FEATURE_INSMOD_LOAD_MAP |
| help |
| Without this option, -m will only output section |
| load map. With this option, -m will also output |
| symbols load map. |
| |
| config RMMOD |
| bool "rmmod" |
| default n |
| depends on !MODPROBE_SMALL |
| help |
| rmmod is used to unload specified modules from the kernel. |

| config LSMOD |
| bool "lsmod" |

| lsmod is used to display a list of loaded modules. |
| |
| config FEATURE_LSMOD_PRETTY_2_6_OUTPUT |
| bool "Pretty output for 2.6.x Linux kernels" |
| default n |
| depends on LSMOD |
| help |
| This option makes output format of lsmod adjusted to |
| the format of module-init-tools for Linux kernel 2.6. |
| |
| config MODPROBE |
| bool "modprobe" |
| default n |
| depends on !MODPROBE_SMALL |
| help |
| Handle the loading of modules, and their dependencies on a high |
| level. |
| |
| Note that in the state, modprobe does not understand multiple |
| module options from the configuration file. See option below. |
| |
| config FEATURE_MODPROBE_MULTIPLE_OPTIONS |
| bool |
| prompt "Multiple options parsing" |
| default y |
| depends on MODPROBE |
| help |
| Allow modprobe to understand more than one option to pass to |
| modules. |
| |
| This is a WIP, while waiting for a common argument parsing |
| common amongst all BB applets (shell, modprobe, etc...) and |
| adds around 600 bytes on x86, 700 bytes on ARM. The code is |
| biggish and uggly, but just works. |
| |
| Saying Y here is not a bad idea if you're not that short |
| on storage capacity. |
| |
| config FEATURE_MODPROBE_FANCY_ALIAS |
| bool |
| prompt "Fancy alias parsing" |
| default y |
| depends on MODPROBE && FEATURE_2_6_MODULES |
| help |
| Say 'y' here to enable parsing of aliases with underscore/dash |
| mismatch between module name and file name, along with bus-specific |
| aliases (such as pci:... or usb:... aliases). |
| |
| config FEATURE_MODPROBE_BLACKLIST |
| bool |
| prompt "Blacklist support" |
| default n |
| depends on MODPROBE && FEATURE_2_6_MODULES |
| help |
| Say 'y' here to enable support for the 'blacklist' command in |
| modprobe.conf. This prevents the alias resolver to resolve |
| blacklisted modules. This is useful if you want to prevent your |
| hardware autodetection scripts to load modules like evdev, frame |
| buffer drivers etc. |
