| config FEATURE_2_4_MODULES |
| bool "Support version 2.2/2.4 Linux kernels" |
| default n |
| depends on INSMOD || RMMOD || LSMOD |
| select PLATFORM_LINUX |
| help |
| Support module loading for 2.2.x and 2.4.x Linux kernels. |
| This increases size considerably. Say N unless you plan |
| to run ancient kernels. |
| |
| config FEATURE_INSMOD_TRY_MMAP |
| bool "Try to load module from a mmap'ed area" |
| default n |
| depends on INSMOD || MODPROBE_SMALL |
| select PLATFORM_LINUX |
| help |
| This option causes module loading code to try to mmap |
| module first. If it does not work (for example, |
| it does not work for compressed modules), module will be read |
| (and unpacked if needed) into a memory block allocated by malloc. |
| |
| The only case when mmap works but malloc does not is when |
| you are trying to load a big module on a very memory-constrained |
| machine. Malloc will momentarily need 2x as much memory as mmap. |
| |
| Choosing N saves about 250 bytes of code (on 32-bit x86). |
| |
| config FEATURE_INSMOD_VERSION_CHECKING |
| bool "Enable module version checking" |
| default n |
| depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| help |
| Support checking of versions for modules. This is used to |
| ensure that the kernel and module are made for each other. |
| |
| config FEATURE_INSMOD_KSYMOOPS_SYMBOLS |
| bool "Add module symbols to kernel symbol table" |
| default n |
| depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| help |
| By adding module symbols to the kernel symbol table, Oops messages |
| occuring within kernel modules can be properly debugged. By enabling |
| this feature, module symbols will always be added to the kernel symbol |
| table for proper debugging support. If you are not interested in |
| Oops messages from kernel modules, say N. |
| |
| config FEATURE_INSMOD_LOADINKMEM |
| bool "In kernel memory optimization (uClinux only)" |
| default n |
| depends on FEATURE_2_4_MODULES && (INSMOD || MODPROBE) |
| select PLATFORM_LINUX |
| help |
| This is a special uClinux only memory optimization that lets insmod |
| load the specified kernel module directly into kernel space, reducing |
| memory usage by preventing the need for two copies of the module |
| being loaded into memory. |
| |
| config FEATURE_INSMOD_LOAD_MAP |
| bool "Enable insmod load map (-m) option" |
| default n |
| depends on FEATURE_2_4_MODULES && INSMOD |
| select PLATFORM_LINUX |
| help |
| Enabling this, one would be able to get a load map |
| output on stdout. This makes kernel module debugging |
| easier. |
| If you don't plan to debug kernel modules, you |
| don't need this option. |
| |
| config FEATURE_INSMOD_LOAD_MAP_FULL |
| bool "Symbols in load map" |
| default y |
| depends on FEATURE_INSMOD_LOAD_MAP && !MODPROBE_SMALL |
| select PLATFORM_LINUX |
| help |
| Without this option, -m will only output section |
| load map. With this option, -m will also output |
| symbols load map. |
| |
| config FEATURE_CHECK_TAINTED_MODULE |
| bool "Support tainted module checking with new kernels" |
| default y |
| depends on (LSMOD || FEATURE_2_4_MODULES) && !MODPROBE_SMALL |
| select PLATFORM_LINUX |
| help |
| Support checking for tainted modules. These are usually binary |
| only modules that will make the linux-kernel list ignore your |
| support request. |
| This option is required to support GPLONLY modules. |
| |
| config FEATURE_MODUTILS_ALIAS |
| bool "Support for module.aliases file" |
| default y |
| depends on DEPMOD || MODPROBE |
| select PLATFORM_LINUX |
| help |
| Generate and parse modules.alias containing aliases for bus |
| identifiers: |
| alias pcmcia:m*c*f03fn*pfn*pa*pb*pc*pd* parport_cs |
| |
| and aliases for logical modules names e.g.: |
| alias padlock_aes aes |
| alias aes_i586 aes |
| alias aes_generic aes |
| |
| Say Y if unsure. |
| |
| config FEATURE_MODUTILS_SYMBOLS |
| bool "Support for module.symbols file" |
| default y |
| depends on DEPMOD || MODPROBE |
| select PLATFORM_LINUX |
| help |
| Generate and parse modules.symbols containing aliases for |
| symbol_request() kernel calls, such as: |
| alias symbol:usb_sg_init usbcore |
| |
| Say Y if unsure. |
| |
| config DEFAULT_MODULES_DIR |
| string "Default directory containing modules" |
| default "/lib/modules" |
| depends on DEPMOD || MODPROBE || MODPROBE_SMALL || MODINFO |
| help |
| Directory that contains kernel modules. |
| Defaults to "/lib/modules" |
| |
| config DEFAULT_DEPMOD_FILE |
| string "Default name of modules.dep" |
| default "modules.dep" |
| depends on DEPMOD || MODPROBE || MODPROBE_SMALL || MODINFO |
| help |
| Filename that contains kernel modules dependencies. |
| Defaults to "modules.dep" |
