bool "Enable loadable module support"
help
- Kernel modules are small pieces of compiled code which can
- be inserted in the running kernel, rather than being
- permanently built into the kernel. You use the "modprobe"
- tool to add (and sometimes remove) them. If you say Y here,
- many parts of the kernel can be built as modules (by
- answering M instead of Y where indicated): this is most
- useful for infrequently used options which are not required
- for booting. For more information, see the man pages for
- modprobe, lsmod, modinfo, insmod and rmmod.
-
- If you say Y here, you will need to run "make
- modules_install" to put the modules under /lib/modules/
- where modprobe can find them (you may need to be root to do
- this).
+ This option allows the kernel to load Kernel modules
+ at runtime to increase functionality, support new
+ devices and so on.
+
+ Kernel modules are compiled code such as device drivers
+ and filesystems. You can use the "lsmod" command to see
+ what modules are currently loaded, and "modprobe" to
+ add (and sometimes remove) them.
+
+ If you say Y here, many parts of the kernel can be built as
+ modules (by answering M instead of Y where indicated). This
+ reduces the size of the compiled kernel and allows you to
+ choose at runtime which modules will be loaded. With some
+ other options enabled, module loading and unloading can be
+ performed automatically by the kernel upon demand.
+
+ If you say Y here, you will need to run "make modules_install"
+ after building the kernel to put the modules under /lib/modules/
+ where "modprobe" can find them. You probably need to be root to
+ install the modules.
If unsure, say Y.
