8 | config DEFAULT_MODULES_DIR |
9 | string "Default directory containing modules" |
10 | default "/lib/modules" |
11 | help |
12 | Directory that contains kernel modules. |
13 | Defaults to "/lib/modules" |
14 | |
15 | config DEFAULT_DEPMOD_FILE |
16 | string "Default name of modules.dep" |
17 | default "modules.dep" |
18 | help |
19 | Filename that contains kernel modules dependencies. |
20 | Defaults to "modules.dep" |
21 | |
22 | config MODPROBE_SMALL |
23 | bool "Simplified modutils" |
24 | default n |
25 | help |
26 | Simplified modutils. |
27 | |
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_). |
35 | |
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. |
40 | |
41 | NB: modules.dep.bb file format is not compatible |
42 | with modules.dep file as created/used by standard module tools. |
43 | |
44 | Additional module parameters can be stored in |
45 | /etc/modules/$module_name files. |
46 | |
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 |
51 | |
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" |
57 | default n |
58 | depends on MODPROBE_SMALL |
59 | help |
60 | Allow insmod and modprobe take module options from command line. |
61 | N.B. Very bloaty. |
62 | |
63 | config FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED |
64 | bool "Skip loading of already loaded modules" |
65 | default n |
66 | depends on MODPROBE_SMALL |
67 | help |
68 | Check if the module is already loaded. |
69 | N.B. It's racy. |
70 | |
71 | config INSMOD |
72 | bool "insmod" |
73 | default n |
74 | depends on !MODPROBE_SMALL |
75 | help |
76 | insmod is used to load specified modules in the running kernel. |
77 | |
78 | config RMMOD |
79 | bool "rmmod" |
80 | default n |
81 | depends on !MODPROBE_SMALL |
82 | help |
83 | rmmod is used to unload specified modules from the kernel. |
84 | |
85 | config LSMOD |
86 | bool "lsmod" |
87 | default n |
88 | depends on !MODPROBE_SMALL |
89 | help |
90 | lsmod is used to display a list of loaded modules. |
91 | |
92 | config FEATURE_LSMOD_PRETTY_2_6_OUTPUT |
93 | bool "Pretty output" |
94 | default n |
95 | depends on LSMOD |
96 | help |
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. |
100 | |
101 | config MODPROBE |
102 | bool "modprobe" |
103 | default n |
104 | depends on !MODPROBE_SMALL |
105 | help |
106 | Handle the loading of modules, and their dependencies on a high |
107 | level. |
108 | |
109 | Note that in the state, modprobe does not understand multiple |
110 | module options from the configuration file. See option below. |
111 | |
112 | config FEATURE_MODPROBE_BLACKLIST |
113 | bool |
114 | prompt "Blacklist support" |
115 | default n |
116 | depends on MODPROBE |
117 | help |
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 |
122 | buffer drivers etc. |
123 | |
124 | config DEPMOD |
125 | bool "depmod" |
126 | default n |
127 | depends on !MODPROBE_SMALL |
128 | help |
129 | depmod generates modules.dep (and potentially modules.alias |
130 | and modules.symbols) that contain dependency information |
131 | for modprobe. |

135 | config FEATURE_2_4_MODULES |
136 | bool "Support version 2.2/2.4 Linux kernels" |
137 | default n |
138 | depends on INSMOD || RMMOD || LSMOD |
139 | help |
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. |
143 | |
144 | config FEATURE_INSMOD_VERSION_CHECKING |
145 | bool "Enable module version checking" |
146 | default n |
147 | depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
148 | help |
149 | Support checking of versions for modules. This is used to |
150 | ensure that the kernel and module are made for each other. |
151 | |
152 | config FEATURE_INSMOD_KSYMOOPS_SYMBOLS |
153 | bool "Add module symbols to kernel symbol table" |
154 | default n |
155 | depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
156 | help |
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. |
162 | |
163 | config FEATURE_INSMOD_LOADINKMEM |
164 | bool "In kernel memory optimization (uClinux only)" |
165 | default n |
166 | depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
167 | help |
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. |
172 | |
173 | config FEATURE_INSMOD_LOAD_MAP |
174 | bool "Enable insmod load map (-m) option" |
175 | default n |
176 | depends on FEATURE_2_4_MODULES && INSMOD |
177 | help |
178 | Enabling this, one would be able to get a load map |
179 | output on stdout. This makes kernel module debugging |
180 | easier. |
181 | If you don't plan to debug kernel modules, you |
182 | don't need this option. |
183 | |
184 | config FEATURE_INSMOD_LOAD_MAP_FULL |
185 | bool "Symbols in load map" |
186 | default y |
187 | depends on FEATURE_INSMOD_LOAD_MAP && !MODPROBE_SMALL |
188 | help |
189 | Without this option, -m will only output section |
190 | load map. With this option, -m will also output |
191 | symbols load map. |
192 | |
193 | config FEATURE_CHECK_TAINTED_MODULE |
194 | bool "Support tainted module checking with new kernels" |
195 | default y |
196 | depends on !MODPROBE_SMALL |
197 | help |
198 | Support checking for tainted modules. These are usually binary |
199 | only modules that will make the linux-kernel list ignore your |
200 | support request. |
201 | This option is required to support GPLONLY modules. |
202 | |
203 | config FEATURE_MODUTILS_ALIAS |
204 | bool "Support for module.aliases file" |
205 | default y |
206 | depends on DEPMOD || MODPROBE |
207 | help |
208 | Generate and parse modules.alias containing aliases for bus |
209 | identifiers: |
210 | alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs |
211 | |
212 | and aliases for logical modules names e.g.: |
213 | alias padlock_aes aes |
214 | alias aes_i586 aes |
215 | alias aes_generic aes |
216 | |
217 | Say Y if unsure. |
218 | |
219 | config FEATURE_MODUTILS_SYMBOLS |
220 | bool "Support for module.symbols file" |
221 | default y |
222 | depends on DEPMOD || MODPROBE |
223 | help |
224 | Generate and parse modules.symbols containing aliases for |
225 | symbol_request() kernel calls, such as: |
226 | alias symbol:usb_sg_init usbcore |
227 | |
228 | Say Y if unsure. |
