| 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_BLACKLIST |
| bool "Blacklist support" |
| default n |
| depends on MODPROBE |
| select PLATFORM_LINUX |
| 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. |
| |
| config DEPMOD |
| bool "depmod" |

| config FEATURE_2_4_MODULES |
| bool "Support version 2.2/2.4 Linux kernels" |
| default n |
| depends on INSMOD || RMMOD || LSMOD |
| select PLATFORM_LINUX |
| help |
| Support module loading for 2.2.x and 2.4.x Linux kernels. |
| This increases size considerably. Say N unless you plan |
| to run ancient kernels. |
| |
| config FEATURE_INSMOD_TRY_MMAP |
| bool "Try to load module from a mmap'ed area" |
| default n |
| depends on INSMOD || MODPROBE_SMALL |
| select PLATFORM_LINUX |
| 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). |
| |
| config FEATURE_INSMOD_VERSION_CHECKING |
| bool "Enable module version checking" |
| default n |
| depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| 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 FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| 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 proper 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 FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| 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 insmod load map (-m) option" |
| default n |
| depends on FEATURE_2_4_MODULES && INSMOD |
| select PLATFORM_LINUX |
| 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. |

| symbols load map. |

| Support checking for tainted modules. These are usually binary |
| only modules that will make the linux-kernel list ignore your |
| support request. |
| This option is required to support GPLONLY modules. |

| config FEATURE_MODUTILS_ALIAS |
| bool "Support for module.aliases file" |
