- 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).

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).
Build limited by a third config symbol which may be =y or =m
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A common idiom that we see (and sometimes have problems with) is this:
When option C in B (module or subsystem) uses interfaces from A (module
or subsystem), and both A and B are tristate (could be =y or =m if they
were independent of each other, but they aren't), then we need to limit
C such that it cannot be built statically if A is built as a loadable
module. (C already depends on B, so there is no dependency issue to
take care of here.)
If A is linked statically into the kernel image, C can be built
statically or as loadable module(s). However, if A is built as loadable
module(s), then C must be restricted to loadable module(s) also. This
can be expressed in kconfig language as:
config C
depends on A = y || A = B
or for real examples, use this command in a kernel tree:
$ find . -name Kconfig\* | xargs grep -ns "depends on.*=.*||.*=" | grep -v orig

help
The section mismatch analysis checks if there are illegal
references from one section to another section.
Linux will during link or during runtime drop some sections
and any use of code/data previously in these sections will
most likely result in an oops.
In the code functions and variables are annotated with
__init, __devinit etc. (see full list in include/linux/init.h)
which result in the code/data being placed in specific sections.
The section mismatch anaylsis are always done after a full
kernel build but enabling this options will in addition
do the following:
- Add the option -fno-inline-functions-called-once to gcc
When inlining a function annotated __init in a non-init
function we would loose the section information and thus
the analysis would not catch the illegal reference.
This options tell gcc to inline less but will also
result in a larger kernel.
- Run the section mismatch analysis for each module/built-in.o
When we run the section mismatch analysis on vmlinux.o we
looses valueable information about where the mismatch was
introduced.
Running the analysis for each module/built-in.o file
will tell where the mismatch happens much closer to the
source. The drawback is that we will report the same
mismatch at least twice.
- Enable verbose reporting from modpost to help solving
the section mismatches reported.
