6 menu "Linux Module Utilities"
8 config DEFAULT_MODULES_DIR
9 string "Default directory containing modules"
10 default "/lib/modules"
12 Directory that contains kernel modules.
13 Defaults to "/lib/modules"
15 config DEFAULT_DEPMOD_FILE
16 string "Default name of modules.dep"
19 Filename that contains kernel modules dependencies.
20 Defaults to "modules.dep"
23 bool "Simplified modutils"
28 With this option modprobe does not require modules.dep file
29 and does not use /etc/modules.conf file.
30 It scans module files in /lib/modules/`uname -r` and
31 determines dependencies and module alias names on the fly.
32 This may make module loading slower, most notably
33 when one needs to load module by alias (this requires
34 scanning through module _bodies_).
36 At the first attempt to load a module by alias modprobe
37 will try to generate modules.dep.bb file in order to speed up
38 future loads by alias. Failure to do so (read-only /lib/modules,
39 etc) is not reported, and future modprobes will be slow too.
41 NB: modules.dep.bb file format is not compatible
42 with modules.dep file as created/used by standard module tools.
44 Additional module parameters can be stored in
45 /etc/modules/$module_name files.
47 Apart from modprobe, other utilities are also provided:
48 - insmod is an alias to modprobe
49 - rmmod is an alias to modprobe -r
50 - depmod generates modules.dep.bb
52 As of 2008-07, this code is experimental. It is 14kb smaller
53 than "non-small" modutils.
55 config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE
56 bool "Accept module options on modprobe command line"
58 depends on MODPROBE_SMALL
60 Allow insmod and modprobe take module options from command line.
63 config FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED
64 bool "Skip loading of already loaded modules"
66 depends on MODPROBE_SMALL
68 Check if the module is already loaded.
74 depends on !MODPROBE_SMALL
76 insmod is used to load specified modules in the running kernel.
81 depends on !MODPROBE_SMALL
83 rmmod is used to unload specified modules from the kernel.
88 depends on !MODPROBE_SMALL
90 lsmod is used to display a list of loaded modules.
92 config FEATURE_LSMOD_PRETTY_2_6_OUTPUT
97 This option makes output format of lsmod adjusted to
98 the format of module-init-tools for Linux kernel 2.6.
99 Increases size somewhat.
104 depends on !MODPROBE_SMALL
106 Handle the loading of modules, and their dependencies on a high
109 Note that in the state, modprobe does not understand multiple
110 module options from the configuration file. See option below.
112 config FEATURE_MODPROBE_BLACKLIST
114 prompt "Blacklist support"
118 Say 'y' here to enable support for the 'blacklist' command in
119 modprobe.conf. This prevents the alias resolver to resolve
120 blacklisted modules. This is useful if you want to prevent your
121 hardware autodetection scripts to load modules like evdev, frame
127 depends on !MODPROBE_SMALL
129 depmod generates modules.dep (and potentially modules.alias
130 and modules.symbols) that contain dependency information
133 comment "Options common to multiple modutils"
135 config FEATURE_2_4_MODULES
136 bool "Support version 2.2/2.4 Linux kernels"
138 depends on INSMOD || RMMOD || LSMOD
140 Support module loading for 2.2.x and 2.4.x Linux kernels.
141 This increases size considerably. Say N unless you plan
142 to run ancient kernels.
144 config FEATURE_INSMOD_VERSION_CHECKING
145 bool "Enable module version checking"
147 depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
149 Support checking of versions for modules. This is used to
150 ensure that the kernel and module are made for each other.
152 config FEATURE_INSMOD_KSYMOOPS_SYMBOLS
153 bool "Add module symbols to kernel symbol table"
155 depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
157 By adding module symbols to the kernel symbol table, Oops messages
158 occuring within kernel modules can be properly debugged. By enabling
159 this feature, module symbols will always be added to the kernel symbol
160 table for properly debugging support. If you are not interested in
161 Oops messages from kernel modules, say N.
163 config FEATURE_INSMOD_LOADINKMEM
164 bool "In kernel memory optimization (uClinux only)"
166 depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE)
168 This is a special uClinux only memory optimization that lets insmod
169 load the specified kernel module directly into kernel space, reducing
170 memory usage by preventing the need for two copies of the module
171 being loaded into memory.
173 config FEATURE_INSMOD_LOAD_MAP
174 bool "Enable insmod load map (-m) option"
176 depends on FEATURE_2_4_MODULES && INSMOD
178 Enabling this, one would be able to get a load map
179 output on stdout. This makes kernel module debugging
181 If you don't plan to debug kernel modules, you
182 don't need this option.
184 config FEATURE_INSMOD_LOAD_MAP_FULL
185 bool "Symbols in load map"
187 depends on FEATURE_INSMOD_LOAD_MAP && !MODPROBE_SMALL
189 Without this option, -m will only output section
190 load map. With this option, -m will also output
193 config FEATURE_CHECK_TAINTED_MODULE
194 bool "Support tainted module checking with new kernels"
196 depends on !MODPROBE_SMALL
198 Support checking for tainted modules. These are usually binary
199 only modules that will make the linux-kernel list ignore your
201 This option is required to support GPLONLY modules.
203 config FEATURE_MODUTILS_ALIAS
204 bool "Support for module.aliases file"
206 depends on DEPMOD || MODPROBE
208 Generate and parse modules.alias containing aliases for bus
210 alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs
212 and aliases for logical modules names e.g.:
213 alias padlock_aes aes
215 alias aes_generic aes
219 config FEATURE_MODUTILS_SYMBOLS
220 bool "Support for module.symbols file"
222 depends on DEPMOD || MODPROBE
224 Generate and parse modules.symbols containing aliases for
225 symbol_request() kernel calls, such as:
226 alias symbol:usb_sg_init usbcore
