12 insmod is used to load specified modules in the running kernel.
14 config FEATURE_INSMOD_VERSION_CHECKING
15 bool "Module version checking"
17 depends on INSMOD && FEATURE_2_4_MODULES
19 Support checking of versions for modules. This is used to
20 ensure that the kernel and module are made for each other.
22 config FEATURE_INSMOD_KSYMOOPS_SYMBOLS
23 bool "Add module symbols to kernel symbol table"
25 depends on INSMOD && FEATURE_2_4_MODULES
27 By adding module symbols to the kernel symbol table, Oops messages
28 occuring within kernel modules can be properly debugged. By enabling
29 this feature, module symbols will always be added to the kernel symbol
30 table for properly debugging support. If you are not interested in
31 Oops messages from kernel modules, say N.
33 config FEATURE_INSMOD_LOADINKMEM
34 bool "In kernel memory optimization (uClinux only)"
36 depends on INSMOD && FEATURE_2_4_MODULES
38 This is a special uClinux only memory optimization that lets insmod
39 load the specified kernel module directly into kernel space, reducing
40 memory usage by preventing the need for two copies of the module
41 being loaded into memory.
43 config FEATURE_INSMOD_LOAD_MAP
44 bool "Enable load map (-m) option"
46 depends on INSMOD && ( FEATURE_2_4_MODULES || FEATURE_2_6_MODULES )
48 Enabling this, one would be able to get a load map
49 output on stdout. This makes kernel module debugging
51 If you don't plan to debug kernel modules, you
52 don't need this option.
54 config FEATURE_INSMOD_LOAD_MAP_FULL
55 bool "Symbols in load map"
57 depends on FEATURE_INSMOD_LOAD_MAP
59 Without this option, -m will only output section
60 load map. With this option, -m will also output
67 rmmod is used to unload specified modules from the kernel.
73 lsmod is used to display a list of loaded modules.
75 config FEATURE_LSMOD_PRETTY_2_6_OUTPUT
76 bool "lsmod pretty output for 2.6.x Linux kernels "
80 This option makes output format of lsmod adjusted to
81 the format of module-init-tools for Linux kernel 2.6.
87 Handle the loading of modules, and their dependencies on a high
90 Note that in the state, modprobe does not understand multiple
91 module options from the configuration file. See option below.
93 config FEATURE_MODPROBE_MULTIPLE_OPTIONS
94 bool "Multiple options parsing" if NITPICK
98 Allow modprobe to understand more than one option to pass to
101 This is a WIP, while waiting for a common argument parsing
102 common amongst all BB applets (shell, modprobe, etc...) and
103 adds around 600 bytes on x86, 700 bytes on ARM. The code is
104 biggish and uggly, but just works.
106 Saying Y here is not a bad idea if you're not that short
109 config FEATURE_MODPROBE_FANCY_ALIAS
110 bool "Fancy alias parsing" if NITPICK
112 depends on MODPROBE && FEATURE_2_6_MODULES
114 Say 'y' here to enable parsing of aliases with underscore/dash
115 mismatch between module name and file name, along with bus-specific
116 aliases (such as pci:... or usb:... aliases).

121 config FEATURE_CHECK_TAINTED_MODULE
122 # Simulate indentation
123 bool "Support tainted module checking with new kernels"
125 depends on INSMOD || LSMOD
127 Support checking for tainted modules. These are usually binary
128 only modules that will make the linux-kernel list ignore your
130 This option is required to support GPLONLY modules.
132 config FEATURE_2_4_MODULES
133 # Simulate indentation
134 bool "Support version 2.2.x to 2.4.x Linux kernels"
136 depends on INSMOD || RMMOD || MODPROBE
138 Support module loading for 2.2.x and 2.4.x Linux kernels.
140 config FEATURE_2_6_MODULES
141 # Simulate indentation
142 bool "Support version 2.6.x Linux kernels"
144 depends on INSMOD || RMMOD || MODPROBE
146 Support module loading for newer 2.6.x Linux kernels.
