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