# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Linux Module Utilities" config DEPMOD bool "depmod" default n help 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 bool "insmod" default n help insmod is used to load specified modules in the running kernel. 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 help rmmod is used to unload specified modules from the kernel. config LSMOD bool "lsmod" default n help 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 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. comment "Options common to multiple modutils" depends on INSMOD || RMMOD || MODPROBE || LSMOD || DEPMOD config FEATURE_CHECK_TAINTED_MODULE # Simulate indentation bool "Support tainted module checking with new kernels" default y depends on INSMOD || LSMOD help 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_2_4_MODULES # Simulate indentation bool "Support version 2.2.x to 2.4.x Linux kernels" default y depends on INSMOD || RMMOD || MODPROBE help Support module loading for 2.2.x and 2.4.x Linux kernels. Note: This is automatically enabled if 2.6 modules are not enabled. config FEATURE_2_6_MODULES # Simulate indentation bool "Support version 2.6.x Linux kernels" default y depends on INSMOD || RMMOD || MODPROBE help Support module loading for newer 2.6.x Linux kernels. config DEFAULT_MODULES_DIR # Simulate indentation string "Default directory containing modules" default "/lib/modules" depends on INSMOD || RMMOD || MODPROBE || DEPMOD help Directory that contains kernel modules. Defaults to "/lib/modules" config DEFAULT_DEPMOD_FILE # Simulate indentation string "Default name of modules.dep" default "modules.dep" depends on INSMOD || RMMOD || MODPROBE || DEPMOD help Filename that contains kernel modules dependencies.
