69 - input prompt: "prompt" <prompt> ["if" <expr>]
73 with "if". If a prompt is not present, the config option is a non-visible

121 - dependencies: "depends on" <expr>
137 - reverse dependencies: "select" <symbol> ["if" <expr>]
148 select should be used with care. select will force
150 By abusing select you are able to select a symbol FOO even
152 In general use select only for non-visible symbols
157 If "select" <symbol> is followed by "if" <expr>, <symbol> will be
163 - weak reverse dependencies: "imply" <symbol> ["if" <expr>]
165 This is similar to "select" as it enforces a lower limit on another
209 - limiting menu display: "visible if" <expr>
217 - numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
224 - help text: "help"

264 (4) If value of <symbol1> is respectively lower, greater, lower-or-equal,
265 or greater-or-equal than value of <symbol2>, it returns 'y',
268 (6) Returns the result of (2-/expr/).
276 There are two types of symbols: constant and non-constant symbols.
277 Non-constant symbols are the most common ones and are defined with the
278 'config' statement. Non-constant symbols consist entirely of alphanumeric

303 The other way to generate the menu structure is done by analyzing the
309 - the child entry must become invisible, if the parent is set to 'n'
310 - the child entry must only be visible, if the parent is visible::

470 The recommended way to do so is to use a config variable named HAVE_*
485 obj-$(CONFIG_GENERIC_IOMAP) += iomap.o
490 select ...
491 select HAVE_GENERIC_IOMAP
492 select ...
495 config variable to select HAVE_GENERIC_IOMAP.
498 introduced to overcome the limitation of select which will force a
501 situation where select forces a symbol equals to 'y'.
506 There are several features that need compiler support. The recommended way
512 depends on $(cc-option,-fstack-protector)
519 def_bool $(success,$(srctree)/scripts/cc-check-foo.sh $(CC))
523 To restrict a component build to module-only, qualify its config symbol
531 Compile-testing
537 it allows continuous-integration systems to compile-test the code on a more
538 common system, and detect bugs that way.
539 Note that compile-tested code should avoid crashing when run on a system where
547 architectures and platforms. This is especially true for on-SoC IP cores,
559 Such a dependency can be relaxed by combining it with the compile-testing rule
571 when trying to use that loadable module from a built-in driver.
573 The most common way to express this optional dependency in Kconfig logic
594 Much less favorable way to express optional dependency is IS_REACHABLE() within
606 discarded, when CONFIG_BAR=m and this code is built-in. This is not what users
