Introduction
|
||||
------------
|
||||
|
||||
The configuration database is a collection of configuration options
|
||||
organized in a tree structure:
|
||||
|
||||
+- Code maturity level options
|
||||
| +- Prompt for development and/or incomplete code/drivers
|
||||
+- General setup
|
||||
| +- Networking support
|
||||
| +- System V IPC
|
||||
| +- BSD Process Accounting
|
||||
| +- Sysctl support
|
||||
+- Loadable module support
|
||||
| +- Enable loadable module support
|
||||
| +- Set version information on all module symbols
|
||||
| +- Kernel module loader
|
||||
+- ...
|
||||
|
||||
Every entry has its own dependencies. These dependencies are used
|
||||
to determine the visibility of an entry. Any child entry is only
|
||||
visible if its parent entry is also visible.
|
||||
|
||||
Menu entries
|
||||
------------
|
||||
|
||||
Most entries define a config option; all other entries help to organize
|
||||
them. A single configuration option is defined like this:
|
||||
|
||||
config MODVERSIONS
|
||||
bool "Set version information on all module symbols"
|
||||
depends on MODULES
|
||||
help
|
||||
Usually, modules have to be recompiled whenever you switch to a new
|
||||
kernel. ...
|
||||
|
||||
Every line starts with a key word and can be followed by multiple
|
||||
arguments. "config" starts a new config entry. The following lines
|
||||
define attributes for this config option. Attributes can be the type of
|
||||
the config option, input prompt, dependencies, help text and default
|
||||
values. A config option can be defined multiple times with the same
|
||||
name, but every definition can have only a single input prompt and the
|
||||
type must not conflict.
|
||||
|
||||
Menu attributes
|
||||
---------------
|
||||
|
||||
A menu entry can have a number of attributes. Not all of them are
|
||||
applicable everywhere (see syntax).
|
||||
|
||||
- type definition: "bool"/"tristate"/"string"/"hex"/"int"
|
||||
Every config option must have a type. There are only two basic types:
|
||||
tristate and string; the other types are based on these two. The type
|
||||
definition optionally accepts an input prompt, so these two examples
|
||||
are equivalent:
|
||||
|
||||
bool "Networking support"
|
||||
and
|
||||
bool
|
||||
prompt "Networking support"
|
||||
|
||||
- input prompt: "prompt" <prompt> ["if" <expr>]
|
||||
Every menu entry can have at most one prompt, which is used to display
|
||||
to the user. Optionally dependencies only for this prompt can be added
|
||||
with "if".
|
||||
|
||||
- default value: "default" <expr> ["if" <expr>]
|
||||
A config option can have any number of default values. If multiple
|
||||
default values are visible, only the first defined one is active.
|
||||
Default values are not limited to the menu entry where they are
|
||||
defined. This means the default can be defined somewhere else or be
|
||||
overridden by an earlier definition.
|
||||
The default value is only assigned to the config symbol if no other
|
||||
value was set by the user (via the input prompt above). If an input
|
||||
prompt is visible the default value is presented to the user and can
|
||||
be overridden by him.
|
||||
Optionally, dependencies only for this default value can be added with
|
||||
"if".
|
||||
|
||||
- type definition + default value:
|
||||
"def_bool"/"def_tristate" <expr> ["if" <expr>]
|
||||
This is a shorthand notation for a type definition plus a value.
|
||||
Optionally dependencies for this default value can be added with "if".
|
||||
|
||||
- dependencies: "depends on" <expr>
|
||||
This defines a dependency for this menu entry. If multiple
|
||||
dependencies are defined, they are connected with '&&'. Dependencies
|
||||
are applied to all other options within this menu entry (which also
|
||||
accept an "if" expression), so these two examples are equivalent:
|
||||
|
||||
bool "foo" if BAR
|
||||
default y if BAR
|
||||
and
|
||||
depends on BAR
|
||||
bool "foo"
|
||||
default y
|
||||
|
||||
- reverse dependencies: "select" <symbol> ["if" <expr>]
|
||||
While normal dependencies reduce the upper limit of a symbol (see
|
||||
below), reverse dependencies can be used to force a lower limit of
|
||||
another symbol. The value of the current menu symbol is used as the
|
||||
minimal value <symbol> can be set to. If <symbol> is selected multiple
|
||||
times, the limit is set to the largest selection.
|
||||
Reverse dependencies can only be used with boolean or tristate
|
||||
symbols.
|
||||
Note:
|
||||
select should be used with care. select will force
|
||||
a symbol to a value without visiting the dependencies.
|
||||
By abusing select you are able to select a symbol FOO even
|
||||
if FOO depends on BAR that is not set.
|
||||
In general use select only for non-visible symbols
|
||||
(no prompts anywhere) and for symbols with no dependencies.
|
||||
That will limit the usefulness but on the other hand avoid
|
||||
the illegal configurations all over.
|
||||
|
||||
- limiting menu display: "visible if" <expr>
|
||||
This attribute is only applicable to menu blocks, if the condition is
|
||||
false, the menu block is not displayed to the user (the symbols
|
||||
contained there can still be selected by other symbols, though). It is
|
||||
similar to a conditional "prompt" attribute for individual menu
|
||||
entries. Default value of "visible" is true.
|
||||
|
||||
- numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
|
||||
This allows to limit the range of possible input values for int
|
||||
and hex symbols. The user can only input a value which is larger than
|
||||
or equal to the first symbol and smaller than or equal to the second
|
||||
symbol.
|
||||
|
||||
- help text: "help" or "---help---"
|
||||
This defines a help text. The end of the help text is determined by
|
||||
the indentation level, this means it ends at the first line which has
|
||||
a smaller indentation than the first line of the help text.
|
||||
"---help---" and "help" do not differ in behaviour, "---help---" is
|
||||
used to help visually separate configuration logic from help within
|
||||
the file as an aid to developers.
|
||||
|
||||
- misc options: "option" <symbol>[=<value>]
|
||||
Various less common options can be defined via this option syntax,
|
||||
which can modify the behaviour of the menu entry and its config
|
||||
symbol. These options are currently possible:
|
||||
|
||||
- "defconfig_list"
|
||||
This declares a list of default entries which can be used when
|
||||
looking for the default configuration (which is used when the main
|
||||
.config doesn't exists yet.)
|
||||
|
||||
- "modules"
|
||||
This declares the symbol to be used as the MODULES symbol, which
|
||||
enables the third modular state for all config symbols.
|
||||
|
||||
- "env"=<value>
|
||||
This imports the environment variable into Kconfig. It behaves like
|
||||
a default, except that the value comes from the environment, this
|
||||
also means that the behaviour when mixing it with normal defaults is
|
||||
undefined at this point. The symbol is currently not exported back
|
||||
to the build environment (if this is desired, it can be done via
|
||||
another symbol).
|
||||
|
||||
Menu dependencies
|
||||
-----------------
|
||||
|
||||
Dependencies define the visibility of a menu entry and can also reduce
|
||||
the input range of tristate symbols. The tristate logic used in the
|
||||
expressions uses one more state than normal boolean logic to express the
|
||||
module state. Dependency expressions have the following syntax:
|
||||
|
||||
<expr> ::= <symbol> (1)
|
||||
<symbol> '=' <symbol> (2)
|
||||
<symbol> '!=' <symbol> (3)
|
||||
'(' <expr> ')' (4)
|
||||
'!' <expr> (5)
|
||||
<expr> '&&' <expr> (6)
|
||||
<expr> '||' <expr> (7)
|
||||
|
||||
Expressions are listed in decreasing order of precedence.
|
||||
|
||||
(1) Convert the symbol into an expression. Boolean and tristate symbols
|
||||
are simply converted into the respective expression values. All
|
||||
other symbol types result in 'n'.
|
||||
(2) If the values of both symbols are equal, it returns 'y',
|
||||
otherwise 'n'.
|
||||
(3) If the values of both symbols are equal, it returns 'n',
|
||||
otherwise 'y'.
|
||||
(4) Returns the value of the expression. Used to override precedence.
|
||||
(5) Returns the result of (2-/expr/).
|
||||
(6) Returns the result of min(/expr/, /expr/).
|
||||
(7) Returns the result of max(/expr/, /expr/).
|
||||
|
||||
An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
|
||||
respectively for calculations). A menu entry becomes visible when its
|
||||
expression evaluates to 'm' or 'y'.
|
||||
|
||||
There are two types of symbols: constant and non-constant symbols.
|
||||
Non-constant symbols are the most common ones and are defined with the
|
||||
'config' statement. Non-constant symbols consist entirely of alphanumeric
|
||||
characters or underscores.
|
||||
Constant symbols are only part of expressions. Constant symbols are
|
||||
always surrounded by single or double quotes. Within the quote, any
|
||||
other character is allowed and the quotes can be escaped using '\'.
|
||||
|
||||
Menu structure
|
||||
--------------
|
||||
|
||||
The position of a menu entry in the tree is determined in two ways. First
|
||||
it can be specified explicitly:
|
||||
|
||||
menu "Network device support"
|
||||
depends on NET
|
||||
|
||||
config NETDEVICES
|
||||
...
|
||||
|
||||
endmenu
|
||||
|
||||
All entries within the "menu" ... "endmenu" block become a submenu of
|
||||
"Network device support". All subentries inherit the dependencies from
|
||||
the menu entry, e.g. this means the dependency "NET" is added to the
|
||||
dependency list of the config option NETDEVICES.
|
||||
|
||||
The other way to generate the menu structure is done by analyzing the
|
||||
dependencies. If a menu entry somehow depends on the previous entry, it
|
||||
can be made a submenu of it. First, the previous (parent) symbol must
|
||||
be part of the dependency list and then one of these two conditions
|
||||
must be true:
|
||||
- the child entry must become invisible, if the parent is set to 'n'
|
||||
- the child entry must only be visible, if the parent is visible
|
||||
|
||||
config MODULES
|
||||
bool "Enable loadable module support"
|
||||
|
||||
config MODVERSIONS
|
||||
bool "Set version information on all module symbols"
|
||||
depends on MODULES
|
||||
|
||||
comment "module support disabled"
|
||||
depends on !MODULES
|
||||
|
||||
MODVERSIONS directly depends on MODULES, this means it's only visible if
|
||||
MODULES is different from 'n'. The comment on the other hand is always
|
||||
visible when MODULES is visible (the (empty) dependency of MODULES is
|
||||
also part of the comment dependencies).
|
||||
|
||||
|
||||
Kconfig syntax
|
||||
--------------
|
||||
|
||||
The configuration file describes a series of menu entries, where every
|
||||
line starts with a keyword (except help texts). The following keywords
|
||||
end a menu entry:
|
||||
- config
|
||||
- menuconfig
|
||||
- choice/endchoice
|
||||
- comment
|
||||
- menu/endmenu
|
||||
- if/endif
|
||||
- source
|
||||
The first five also start the definition of a menu entry.
|
||||
|
||||
config:
|
||||
|
||||
"config" <symbol>
|
||||
<config options>
|
||||
|
||||
This defines a config symbol <symbol> and accepts any of above
|
||||
attributes as options.
|
||||
|
||||
menuconfig:
|
||||
"menuconfig" <symbol>
|
||||
<config options>
|
||||
|
||||
This is similar to the simple config entry above, but it also gives a
|
||||
hint to front ends, that all suboptions should be displayed as a
|
||||
separate list of options.
|
||||
|
||||
choices:
|
||||
|
||||
"choice" [symbol]
|
||||
<choice options>
|
||||
<choice block>
|
||||
"endchoice"
|
||||
|
||||
This defines a choice group and accepts any of the above attributes as
|
||||
options. A choice can only be of type bool or tristate, while a boolean
|
||||
choice only allows a single config entry to be selected, a tristate
|
||||
choice also allows any number of config entries to be set to 'm'. This
|
||||
can be used if multiple drivers for a single hardware exists and only a
|
||||
single driver can be compiled/loaded into the kernel, but all drivers
|
||||
can be compiled as modules.
|
||||
A choice accepts another option "optional", which allows to set the
|
||||
choice to 'n' and no entry needs to be selected.
|
||||
If no [symbol] is associated with a choice, then you can not have multiple
|
||||
definitions of that choice. If a [symbol] is associated to the choice,
|
||||
then you may define the same choice (ie. with the same entries) in another
|
||||
place.
|
||||
|
||||
comment:
|
||||
|
||||
"comment" <prompt>
|
||||
<comment options>
|
||||
|
||||
This defines a comment which is displayed to the user during the
|
||||
configuration process and is also echoed to the output files. The only
|
||||
possible options are dependencies.
|
||||
|
||||
menu:
|
||||
|
||||
"menu" <prompt>
|
||||
<menu options>
|
||||
<menu block>
|
||||
"endmenu"
|
||||
|
||||
This defines a menu block, see "Menu structure" above for more
|
||||
information. The only possible options are dependencies and "visible"
|
||||
attributes.
|
||||
|
||||
if:
|
||||
|
||||
"if" <expr>
|
||||
<if block>
|
||||
"endif"
|
||||
|
||||
This defines an if block. The dependency expression <expr> is appended
|
||||
to all enclosed menu entries.
|
||||
|
||||
source:
|
||||
|
||||
"source" <prompt>
|
||||
|
||||
This reads the specified configuration file. This file is always parsed.
|
||||
|
||||
mainmenu:
|
||||
|
||||
"mainmenu" <prompt>
|
||||
|
||||
This sets the config program's title bar if the config program chooses
|
||||
to use it. It should be placed at the top of the configuration, before any
|
||||
other statement.
|
||||
|
||||
|
||||
Kconfig hints
|
||||
-------------
|
||||
This is a collection of Kconfig tips, most of which aren't obvious at
|
||||
first glance and most of which have become idioms in several Kconfig
|
||||
files.
|
||||
|
||||
Adding common features and make the usage configurable
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
It is a common idiom to implement a feature/functionality that are
|
||||
relevant for some architectures but not all.
|
||||
The recommended way to do so is to use a config variable named HAVE_*
|
||||
that is defined in a common Kconfig file and selected by the relevant
|
||||
architectures.
|
||||
An example is the generic IOMAP functionality.
|
||||
|
||||
We would in lib/Kconfig see:
|
||||
|
||||
# Generic IOMAP is used to ...
|
||||
config HAVE_GENERIC_IOMAP
|
||||
|
||||
config GENERIC_IOMAP
|
||||
depends on HAVE_GENERIC_IOMAP && FOO
|
||||
|
||||
And in lib/Makefile we would see:
|
||||
obj-$(CONFIG_GENERIC_IOMAP) += iomap.o
|
||||
|
||||
For each architecture using the generic IOMAP functionality we would see:
|
||||
|
||||
config X86
|
||||
select ...
|
||||
select HAVE_GENERIC_IOMAP
|
||||
select ...
|
||||
|
||||
Note: we use the existing config option and avoid creating a new
|
||||
config variable to select HAVE_GENERIC_IOMAP.
|
||||
|
||||
Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is
|
||||
introduced to overcome the limitation of select which will force a
|
||||
config option to 'y' no matter the dependencies.
|
||||
The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the
|
||||
situation where select forces a symbol equals to 'y'.
|
||||
|
||||
Build as module only
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
To restrict a component build to module-only, qualify its config symbol
|
||||
with "depends on m". E.g.:
|
||||
|
||||
config FOO
|
||||
depends on BAR && m
|
||||
|
||||
limits FOO to module (=m) or disabled (=n).
|
||||
|
||||
Kconfig symbol existence
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
The following two methods produce the same kconfig symbol dependencies
|
||||
but differ greatly in kconfig symbol existence (production) in the
|
||||
generated config file.
|
||||
|
||||
case 1:
|
||||
|
||||
config FOO
|
||||
tristate "about foo"
|
||||
depends on BAR
|
||||
|
||||
vs. case 2:
|
||||
|
||||
if BAR
|
||||
config FOO
|
||||
tristate "about foo"
|
||||
endif
|
||||
|
||||
In case 1, the symbol FOO will always exist in the config file (given
|
||||
no other dependencies). In case 2, the symbol FOO will only exist in
|
||||
the config file if BAR is enabled.

|
||||
General
|
||||
--------------------------------------------------
|
||||
|
||||
New kernel releases often introduce new config symbols. Often more
|
||||
important, new kernel releases may rename config symbols. When
|
||||
this happens, using a previously working .config file and running
|
||||
"make oldconfig" won't necessarily produce a working new kernel
|
||||
for you, so you may find that you need to see what NEW kernel
|
||||
symbols have been introduced.
|
||||
|
||||
To see a list of new config symbols when using "make oldconfig", use
|
||||
|
||||
cp user/some/old.config .config
|
||||
yes "" | make oldconfig >conf.new
|
||||
|
||||
and the config program will list as (NEW) any new symbols that have
|
||||
unknown values. Of course, the .config file is also updated with
|
||||
new (default) values, so you can use:
|
||||
|
||||
grep "(NEW)" conf.new
|
||||
|
||||
to see the new config symbols or you can use diffconfig to see the
|
||||
differences between the previous and new .config files:
|
||||
|
||||
scripts/diffconfig .config.old .config | less

Environment variables for '*config'
|
||||
|
||||
KCONFIG_CONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be used to specify a default kernel config
|
||||
file name to override the default name of ".config".
|
||||
|
||||
KCONFIG_OVERWRITECONFIG
|
||||
--------------------------------------------------
|
||||
If you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not
|
||||
break symlinks when .config is a symlink to somewhere else.
|
||||

Environment variables for '{allyes/allmod/allno/rand}config'
|
||||
|
||||
KCONFIG_ALLCONFIG
|
||||
--------------------------------------------------
|
||||
(partially based on lkml email from/by Rob Landley, re: miniconfig)
|
||||
--------------------------------------------------
|
||||
The allyesconfig/allmodconfig/allnoconfig/randconfig variants can also
|
||||
use the environment variable KCONFIG_ALLCONFIG as a flag or a filename
|
||||
that contains config symbols that the user requires to be set to a
|
||||
specific value. If KCONFIG_ALLCONFIG is used without a filename where
|
||||
KCONFIG_ALLCONFIG == "" or KCONFIG_ALLCONFIG == "1", "make *config"
|
||||
checks for a file named "all{yes/mod/no/def/random}.config"
|
||||
(corresponding to the *config command that was used) for symbol values
|
||||
that are to be forced. If this file is not found, it checks for a
|
||||
file named "all.config" to contain forced values.
|
||||
|
||||
This enables you to create "miniature" config (miniconfig) or custom
|
||||
config files containing just the config symbols that you are interested
|
||||
in. Then the kernel config system generates the full .config file,
|
||||
including symbols of your miniconfig file.
|
||||
|
||||
This 'KCONFIG_ALLCONFIG' file is a config file which contains
|
||||
(usually a subset of all) preset config symbols. These variable
|
||||
settings are still subject to normal dependency checks.
|
||||
|
||||
Examples:
|
||||
KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig
|
||||
or
|
||||
KCONFIG_ALLCONFIG=mini.config make allnoconfig
|
||||
or
|
||||
make KCONFIG_ALLCONFIG=mini.config allnoconfig
|
||||
|
||||
These examples will disable most options (allnoconfig) but enable or
|
||||
disable the options that are explicitly listed in the specified
|
||||
mini-config files.

Environment variables for 'silentoldconfig'
|
||||
|
||||
KCONFIG_NOSILENTUPDATE
|
||||
--------------------------------------------------
|
||||
If this variable has a non-blank value, it prevents silent kernel
|
||||
config updates (requires explicit updates).
|
||||
|
||||
KCONFIG_AUTOCONFIG
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"auto.conf" file. Its default value is "include/config/auto.conf".
|
||||
|
||||
KCONFIG_TRISTATE
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the
|
||||
"tristate.conf" file. Its default value is "include/config/tristate.conf".
|
||||
|
||||
KCONFIG_AUTOHEADER
|
||||
--------------------------------------------------
|
||||
This environment variable can be set to specify the path & name of the

|
||||
|
||||
SEARCHING for CONFIG symbols
|
||||
|
||||
Searching in menuconfig:
|
||||
|
||||
The Search function searches for kernel configuration symbol
|
||||
names, so you have to know something close to what you are
|
||||
looking for.
|
||||
|
||||
Example:
|
||||
/hotplug
|
||||
This lists all config symbols that contain "hotplug",
|
||||
e.g., HOTPLUG, HOTPLUG_CPU, MEMORY_HOTPLUG.
|
||||
|
||||
For search help, enter / followed TAB-TAB-TAB (to highlight
|
||||
<Help>) and Enter. This will tell you that you can also use
|
||||
regular expressions (regexes) in the search string, so if you
|
||||
are not interested in MEMORY_HOTPLUG, you could try
|
||||
|
||||
/^hotplug
|
||||
|
||||

xconfig
|
||||
--------------------------------------------------
|
||||
|
||||
Searching in xconfig:
|
||||
|
||||
The Search function searches for kernel configuration symbol
|
||||
names, so you have to know something close to what you are
|
||||
looking for.
|
||||
|
||||
Example:
|
||||
Ctrl-F hotplug
|
||||
or
|
||||
Menu: File, Search, hotplug
|
||||
|
||||
lists all config symbol entries that contain "hotplug" in
|
||||
the symbol name. In this Search dialog, you may change the

None (gconfig isn't maintained as well as xconfig or menuconfig);
|
||||
however, gconfig does have a few more viewing choices than
|
||||
xconfig does.
