config BUSYBOX_CONFIG_MODPROBE_SMALL
bool "Simplified modutils"
default BUSYBOX_DEFAULT_MODPROBE_SMALL
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_CONFIG_DEPMOD
bool "depmod (27 kb)"
default BUSYBOX_DEFAULT_DEPMOD
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
depmod generates modules.dep (and potentially modules.alias
and modules.symbols) that contain dependency information
for modprobe.
config BUSYBOX_CONFIG_INSMOD
bool "insmod (22 kb)"
default BUSYBOX_DEFAULT_INSMOD
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
insmod is used to load specified modules in the running kernel.
config BUSYBOX_CONFIG_LSMOD
bool "lsmod (1.9 kb)"
default BUSYBOX_DEFAULT_LSMOD
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
lsmod is used to display a list of loaded modules.
config BUSYBOX_CONFIG_FEATURE_LSMOD_PRETTY_2_6_OUTPUT
bool "Pretty output"
default BUSYBOX_DEFAULT_FEATURE_LSMOD_PRETTY_2_6_OUTPUT
depends on BUSYBOX_CONFIG_LSMOD && !BUSYBOX_CONFIG_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_CONFIG_MODINFO
bool "modinfo (24 kb)"
default BUSYBOX_DEFAULT_MODINFO
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
Show information about a Linux Kernel module
config BUSYBOX_CONFIG_MODPROBE
bool "modprobe (28 kb)"
default BUSYBOX_DEFAULT_MODPROBE
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
Handle the loading of modules, and their dependencies on a high
level.
config BUSYBOX_CONFIG_FEATURE_MODPROBE_BLACKLIST
bool "Blacklist support"
default BUSYBOX_DEFAULT_FEATURE_MODPROBE_BLACKLIST
depends on BUSYBOX_CONFIG_MODPROBE && !BUSYBOX_CONFIG_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_CONFIG_RMMOD
bool "rmmod (3.3 kb)"
default BUSYBOX_DEFAULT_RMMOD
select BUSYBOX_CONFIG_PLATFORM_LINUX
help
rmmod is used to unload specified modules from the kernel.
comment "Options common to multiple modutils"
config BUSYBOX_CONFIG_FEATURE_CMDLINE_MODULE_OPTIONS
bool "Accept module options on modprobe command line"
default BUSYBOX_DEFAULT_FEATURE_CMDLINE_MODULE_OPTIONS
depends on BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_MODPROBE
help
Allow insmod and modprobe take module options from the applets'
command line.
config BUSYBOX_CONFIG_FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED
bool "Skip loading of already loaded modules"
default BUSYBOX_DEFAULT_FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED
depends on BUSYBOX_CONFIG_MODPROBE_SMALL && (BUSYBOX_CONFIG_DEPMOD || BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_MODPROBE)
help
Check if the module is already loaded.
config BUSYBOX_CONFIG_FEATURE_2_4_MODULES
bool "Support version 2.2/2.4 Linux kernels"
default BUSYBOX_DEFAULT_FEATURE_2_4_MODULES
depends on (BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_LSMOD || BUSYBOX_CONFIG_MODPROBE || BUSYBOX_CONFIG_RMMOD) && !BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_VERSION_CHECKING
bool "Enable module version checking"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_VERSION_CHECKING
depends on BUSYBOX_CONFIG_FEATURE_2_4_MODULES && (BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_KSYMOOPS_SYMBOLS
bool "Add module symbols to kernel symbol table"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_KSYMOOPS_SYMBOLS
depends on BUSYBOX_CONFIG_FEATURE_2_4_MODULES && (BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_LOADINKMEM
bool "In kernel memory optimization (uClinux only)"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_LOADINKMEM
depends on BUSYBOX_CONFIG_FEATURE_2_4_MODULES && (BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_LOAD_MAP
bool "Enable insmod load map (-m) option"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_LOAD_MAP
depends on BUSYBOX_CONFIG_FEATURE_2_4_MODULES && BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_LOAD_MAP_FULL
bool "Symbols in load map"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_LOAD_MAP_FULL
depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_CHECK_TAINTED_MODULE
bool "Support tainted module checking with new kernels"
default BUSYBOX_DEFAULT_FEATURE_CHECK_TAINTED_MODULE
depends on (BUSYBOX_CONFIG_LSMOD || BUSYBOX_CONFIG_FEATURE_2_4_MODULES) && !BUSYBOX_CONFIG_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_CONFIG_FEATURE_INSMOD_TRY_MMAP
bool "Try to load module from a mmap'ed area"
default BUSYBOX_DEFAULT_FEATURE_INSMOD_TRY_MMAP
depends on (BUSYBOX_CONFIG_INSMOD || BUSYBOX_CONFIG_MODPROBE) && !BUSYBOX_CONFIG_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_CONFIG_FEATURE_MODUTILS_ALIAS
bool "Support module.aliases file"
default BUSYBOX_DEFAULT_FEATURE_MODUTILS_ALIAS
depends on (BUSYBOX_CONFIG_DEPMOD || BUSYBOX_CONFIG_MODPROBE) && !BUSYBOX_CONFIG_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_CONFIG_FEATURE_MODUTILS_SYMBOLS
bool "Support module.symbols file"
default BUSYBOX_DEFAULT_FEATURE_MODUTILS_SYMBOLS
depends on (BUSYBOX_CONFIG_DEPMOD || BUSYBOX_CONFIG_MODPROBE) && !BUSYBOX_CONFIG_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_CONFIG_DEFAULT_MODULES_DIR
string "Default directory containing modules"
default BUSYBOX_DEFAULT_DEFAULT_MODULES_DIR
depends on BUSYBOX_CONFIG_DEPMOD || BUSYBOX_CONFIG_MODPROBE || BUSYBOX_CONFIG_MODINFO
help
Directory that contains kernel modules.
Defaults to "/lib/modules"
config BUSYBOX_CONFIG_DEFAULT_DEPMOD_FILE
string "Default name of modules.dep"
default BUSYBOX_DEFAULT_DEFAULT_DEPMOD_FILE
depends on BUSYBOX_CONFIG_DEPMOD || BUSYBOX_CONFIG_MODPROBE || BUSYBOX_CONFIG_MODINFO
help
Filename that contains kernel modules dependencies.
Defaults to "modules.dep".
If you configured the "simplified modutils" (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.
