  7. config BUSYBOX_MODPROBE_SMALL
  8. bool "Simplified modutils"
  9. default y
  10. help
  11. Build smaller (~1.5 kbytes), simplified module tools.
  12. This option by itself does not enable any applets -
  13. you need to select applets individually below.
  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_).
  21. At the first attempt to load a module by alias modprobe
  22. will try to generate modules.dep.bb file in order to speed up
  23. future loads by alias. Failure to do so (read-only /lib/modules,
  24. etc) is not reported, and future modprobes will be slow too.
  25. NB: modules.dep.bb file format is not compatible
  26. with modules.dep file as created/used by standard module tools.
  27. Additional module parameters can be stored in
  28. /etc/modules/$module_name files.
  29. config BUSYBOX_DEPMOD
  30. bool "depmod (27 kb)"
  31. default y
  32. help
  33. depmod generates modules.dep (and potentially modules.alias
  34. and modules.symbols) that contain dependency information
  35. for modprobe.
  36. config BUSYBOX_INSMOD
  37. bool "insmod (22 kb)"
  38. default y
  39. help
  40. insmod is used to load specified modules in the running kernel.
  41. config BUSYBOX_LSMOD
  42. bool "lsmod (1.9 kb)"
  43. default y
  44. help
  45. lsmod is used to display a list of loaded modules.
  46. config BUSYBOX_FEATURE_LSMOD_PRETTY_2_6_OUTPUT
  47. bool "Pretty output"
  48. default y
  49. depends on BUSYBOX_LSMOD && !BUSYBOX_MODPROBE_SMALL
  50. help
  51. This option makes output format of lsmod adjusted to
  52. the format of module-init-tools for Linux kernel 2.6.
  53. Increases size somewhat.
  54. config BUSYBOX_MODINFO
  55. bool "modinfo (24 kb)"
  56. default y
  57. help
  58. Show information about a Linux Kernel module
  59. config BUSYBOX_MODPROBE
  60. bool "modprobe (28 kb)"
  61. default y
  62. help
  63. Handle the loading of modules, and their dependencies on a high
  64. level.
  65. config BUSYBOX_FEATURE_MODPROBE_BLACKLIST
  66. bool "Blacklist support"
  67. default y
  68. depends on BUSYBOX_MODPROBE && !BUSYBOX_MODPROBE_SMALL
  69. help
  70. Say 'y' here to enable support for the 'blacklist' command in
  71. modprobe.conf. This prevents the alias resolver to resolve
  72. blacklisted modules. This is useful if you want to prevent your
  73. hardware autodetection scripts to load modules like evdev, frame
  74. buffer drivers etc.
  75. config BUSYBOX_RMMOD
  76. bool "rmmod (3.3 kb)"
  77. default y
  78. help
  79. rmmod is used to unload specified modules from the kernel.
  80. comment "Options common to multiple modutils"
  81. config BUSYBOX_FEATURE_CMDLINE_MODULE_OPTIONS
  82. bool "Accept module options on modprobe command line"
  83. default y
  84. depends on BUSYBOX_INSMOD || BUSYBOX_MODPROBE
  85. help
  86. Allow insmod and modprobe take module options from the applets'
  87. command line.
  88. config BUSYBOX_FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED
  89. bool "Skip loading of already loaded modules"
  90. default y
  91. depends on BUSYBOX_MODPROBE_SMALL && (BUSYBOX_DEPMOD || BUSYBOX_INSMOD || BUSYBOX_MODPROBE)

  96. default n
  97. depends on (BUSYBOX_INSMOD || BUSYBOX_LSMOD || BUSYBOX_MODPROBE || BUSYBOX_RMMOD) && !BUSYBOX_MODPROBE_SMALL
  98. help
  99. Support module loading for 2.2.x and 2.4.x Linux kernels.
  100. This increases size considerably. Say N unless you plan
  101. to run ancient kernels.
  102. config BUSYBOX_FEATURE_INSMOD_VERSION_CHECKING
  103. bool "Enable module version checking"
  104. default n
  105. depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
  106. help
  107. Support checking of versions for modules. This is used to
  108. ensure that the kernel and module are made for each other.
  109. config BUSYBOX_FEATURE_INSMOD_KSYMOOPS_SYMBOLS
  110. bool "Add module symbols to kernel symbol table"
  111. default n
  112. depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
  113. help
  114. By adding module symbols to the kernel symbol table, Oops messages
  115. occurring within kernel modules can be properly debugged. By enabling
  116. this feature, module symbols will always be added to the kernel symbol
  117. table for proper debugging support. If you are not interested in
  118. Oops messages from kernel modules, say N.
  119. config BUSYBOX_FEATURE_INSMOD_LOADINKMEM
  120. bool "In kernel memory optimization (uClinux only)"
  121. default n
  122. depends on BUSYBOX_FEATURE_2_4_MODULES && (BUSYBOX_INSMOD || BUSYBOX_MODPROBE)
  123. help
  124. This is a special uClinux only memory optimization that lets insmod
  125. load the specified kernel module directly into kernel space, reducing
  126. memory usage by preventing the need for two copies of the module
  127. being loaded into memory.
  128. config BUSYBOX_FEATURE_INSMOD_LOAD_MAP
  129. bool "Enable insmod load map (-m) option"
  130. default n
  131. depends on BUSYBOX_FEATURE_2_4_MODULES && BUSYBOX_INSMOD
  132. help
  133. Enabling this, one would be able to get a load map
  134. output on stdout. This makes kernel module debugging
  135. easier.
  136. If you don't plan to debug kernel modules, you
  137. don't need this option.
  138. config BUSYBOX_FEATURE_INSMOD_LOAD_MAP_FULL
  139. bool "Symbols in load map"
  140. default y
  141. depends on BUSYBOX_FEATURE_INSMOD_LOAD_MAP
  142. help
  143. Without this option, -m will only output section
  144. load map. With this option, -m will also output
  145. symbols load map.
  146. config BUSYBOX_FEATURE_CHECK_TAINTED_MODULE
  147. bool "Support tainted module checking with new kernels"
  148. default y
  149. depends on (BUSYBOX_LSMOD || BUSYBOX_FEATURE_2_4_MODULES) && !BUSYBOX_MODPROBE_SMALL
  150. help
  151. Support checking for tainted modules. These are usually binary
  152. only modules that will make the linux-kernel list ignore your
  153. support request.
  154. This option is required to support GPLONLY modules.
  155. config BUSYBOX_FEATURE_INSMOD_TRY_MMAP
  156. bool "Try to load module from a mmap'ed area"
  157. default n
  158. depends on (BUSYBOX_INSMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL
  159. help
  160. This option causes module loading code to try to mmap
  161. module first. If it does not work (for example,
  162. it does not work for compressed modules), module will be read
  163. (and unpacked if needed) into a memory block allocated by malloc.
  164. The only case when mmap works but malloc does not is when
  165. you are trying to load a big module on a very memory-constrained
  166. machine. Malloc will momentarily need 2x as much memory as mmap.
  167. Choosing N saves about 250 bytes of code (on 32-bit x86).
  168. config BUSYBOX_FEATURE_MODUTILS_ALIAS
  169. bool "Support module.aliases file"
  170. default y
  171. depends on (BUSYBOX_DEPMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL

  174. identifiers:
  175. alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs
  176. and aliases for logical modules names e.g.:
  177. alias padlock_aes aes
  178. alias aes_i586 aes
  179. alias aes_generic aes
  180. Say Y if unsure.
  181. config BUSYBOX_FEATURE_MODUTILS_SYMBOLS
  182. bool "Support module.symbols file"
  183. default y
  184. depends on (BUSYBOX_DEPMOD || BUSYBOX_MODPROBE) && !BUSYBOX_MODPROBE_SMALL
  185. help
  186. Generate and parse modules.symbols containing aliases for
  187. symbol_request() kernel calls, such as:
  188. alias symbol:usb_sg_init usbcore
  189. Say Y if unsure.
  190. config BUSYBOX_DEFAULT_MODULES_DIR

  201. help
  202. Filename that contains kernel modules dependencies.
  203. Defaults to "modules.dep".
  204. If you configured the "simplified modutils" (BUSYBOX_MODPROBE_SMALL), a
  205. ".bb" suffix will be added after this name. Do not specify ".bb"
  206. here unless you intend your depmod or modprobe to work on
  207. "modules.dep.bb.bb" or such.
