- config BUSYBOX_MODPROBE_SMALL
- bool "Simplified modutils"
- default y
- help
- Build smaller (~1.5 kbytes), simplified module tools.
- This option by itself does not enable any applets -
- you need to select applets individually below.
- 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.
- config BUSYBOX_DEPMOD
- bool "depmod (27 kb)"
- default y
- help
- depmod generates modules.dep (and potentially modules.alias
- and modules.symbols) that contain dependency information
- for modprobe.
- config BUSYBOX_INSMOD
- bool "insmod (22 kb)"
- default y
- help
- insmod is used to load specified modules in the running kernel.
- config BUSYBOX_LSMOD
- bool "lsmod (1.9 kb)"
- default y
- help
- lsmod is used to display a list of loaded modules.
- config BUSYBOX_FEATURE_LSMOD_PRETTY_2_6_OUTPUT
- bool "Pretty output"
- default y
- depends on BUSYBOX_LSMOD && !BUSYBOX_MODPROBE_SMALL
- help
- This option makes output format of lsmod adjusted to
- the format of module-init-tools for Linux kernel 2.6.
- Increases size somewhat.
- config BUSYBOX_MODINFO
- bool "modinfo (24 kb)"
- default y
- help
- Show information about a Linux Kernel module
- config BUSYBOX_MODPROBE
- bool "modprobe (28 kb)"
- default y
- help
- Handle the loading of modules, and their dependencies on a high
- level.
- config BUSYBOX_FEATURE_MODPROBE_BLACKLIST
- bool "Blacklist support"
- default y
- depends on BUSYBOX_MODPROBE && !BUSYBOX_MODPROBE_SMALL
- 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 BUSYBOX_RMMOD
- bool "rmmod (3.3 kb)"
- default y
- help
- rmmod is used to unload specified modules from the kernel.
- comment "Options common to multiple modutils"
- config BUSYBOX_FEATURE_CMDLINE_MODULE_OPTIONS
- bool "Accept module options on modprobe command line"
- default y
- depends on BUSYBOX_INSMOD || BUSYBOX_MODPROBE
- help
- Allow insmod and modprobe take module options from the applets'
- command line.
- config BUSYBOX_FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED
- bool "Skip loading of already loaded modules"
- default y
- depends on BUSYBOX_MODPROBE_SMALL && (BUSYBOX_DEPMOD || BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
- help
- Check if the module is already loaded.
- config BUSYBOX_FEATURE_2_4_MODULES
- bool "Support version 2.2/2.4 Linux kernels"
- default n
- depends on (BUSYBOX_INSMOD || BUSYBOX_LSMOD || BUSYBOX_MODPROBE || BUSYBOX_RMMOD) && !BUSYBOX_MODPROBE_SMALL
- 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 BUSYBOX_FEATURE_INSMOD_VERSION_CHECKING
- bool "Enable module version checking"
- default n
- depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
- help
- Support checking of versions for modules. This is used to
- ensure that the kernel and module are made for each other.
- config BUSYBOX_FEATURE_INSMOD_KSYMOOPS_SYMBOLS
- bool "Add module symbols to kernel symbol table"
- default n
- depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
- help
- By adding module symbols to the kernel symbol table, Oops messages
- occurring 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 BUSYBOX_FEATURE_INSMOD_LOADINKMEM
- bool "In kernel memory optimization (uClinux only)"
- default n
- depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
- 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 BUSYBOX_FEATURE_INSMOD_LOAD_MAP
- bool "Enable insmod load map (-m) option"
- default n
- depends on BUSYBOX_FEATURE_2_4_MODULES && BUSYBOX_INSMOD
- 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 BUSYBOX_FEATURE_INSMOD_LOAD_MAP_FULL
- bool "Symbols in load map"
- default y
- depends on BUSYBOX_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 BUSYBOX_FEATURE_CHECK_TAINTED_MODULE
- bool "Support tainted module checking with new kernels"
- default y
- depends on (BUSYBOX_LSMOD || BUSYBOX_FEATURE_2_4_MODULES) && !BUSYBOX_MODPROBE_SMALL
- 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 BUSYBOX_FEATURE_INSMOD_TRY_MMAP
- bool "Try to load module from a mmap'ed area"
- default n
- depends on (BUSYBOX_INSMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL
- 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 BUSYBOX_FEATURE_MODUTILS_ALIAS
- bool "Support module.aliases file"
- default y
- depends on (BUSYBOX_DEPMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL
- help
- Generate and parse modules.alias containing aliases for bus
- identifiers:
- alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs
- and aliases for logical modules names e.g.:
- alias padlock_aes aes
- alias aes_i586 aes
- alias aes_generic aes
- Say Y if unsure.
- config BUSYBOX_FEATURE_MODUTILS_SYMBOLS
- bool "Support module.symbols file"
- default y
- depends on (BUSYBOX_DEPMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL
- help
- Generate and parse modules.symbols containing aliases for
- symbol_request() kernel calls, such as:
- alias symbol:usb_sg_init usbcore
- Say Y if unsure.
- config BUSYBOX_DEFAULT_MODULES_DIR
- string "Default directory containing modules"
- default "/lib/modules"
- depends on BUSYBOX_DEPMOD || BUSYBOX_MODPROBE || BUSYBOX_MODINFO
- help
- Directory that contains kernel modules.
- Defaults to "/lib/modules"
- config BUSYBOX_DEFAULT_DEPMOD_FILE
- string "Default name of modules.dep"
- default "modules.dep"
- depends on BUSYBOX_DEPMOD || BUSYBOX_MODPROBE || BUSYBOX_MODINFO
- help
- Filename that contains kernel modules dependencies.
- Defaults to "modules.dep".
- If you configured the "simplified modutils" (BUSYBOX_MODPROBE_SMALL), a
- ".bb" suffix will be added after this name. Do not specify ".bb"
- here unless you intend your depmod or modprobe to work on
- "modules.dep.bb.bb" or such.
