Kernel specific |
|
||||
----------------+
|
||||
|
||||
A kernel is defined by:
|
||||
|
||||
- a human-readable name, in lower case letters, with numbers as appropriate.
|
||||
The underscore is allowed; space and special characters are not (although
|
||||
they are internally replaced with underscores.
|
||||
Eg.: linux, bare-metal
|
||||
- a file in "config/kernel/", named after the kernel name, and suffixed with
|
||||
".in".
|
||||
Eg.: config/kernel/linux.in, config/kernel/bare-metal.in
|
||||
|
||||
The kernel's ".in" file must contain:
|
||||
> an optional lines containing exactly "# EXPERIMENTAL", starting on the
|
||||
first column, and without any following space or other character.
|
||||
If this line is present, then this kernel is considered EXPERIMENTAL,
|
||||
and correct dependency on EXPERIMENTAL will be set.
|
||||
> the config option "KERNEL_%kernel_name%" (where %kernel_name% is to be
|
||||
replaced with the actual kernel name, with all special characters and
|
||||
spaces replaced by underscores).
|
||||
That config option must have *neither* a type, *nor* a prompt! Also, it can
|
||||
*not* depends on EXPERIMENTAL.
|
||||
Eg.: KERNEL_linux, KERNEL_bare_metal
|
||||
+ mandatory:
|
||||
defines a (terse) help entry for this kernel.
|
||||
Eg.:
|
||||
config KERNEL_bare_metal
|
||||
help
|
||||
Build a compiler for use without any kernel.
|
||||
+ optional:
|
||||
selects adequate associated config options.
|
||||
Eg.:
|
||||
config KERNEL_bare_metal
|
||||
select BARE_METAL
|
||||
help
|
||||
Build a compiler for use without any kernel.
|
||||
|
||||
> other kernel specific options, at your discretion. Note however that, to
|
||||
avoid name-clashing, such options should be prefixed with
|
||||
"KERNEL_%kernel_name%", where %kernel_name% is again tp be replaced with
|
||||
the actual kernel name.
|
||||
(Note: due to historical reasons, and lack of time to clean up the code,
|
||||
I may have left some config options that do not completely conform to
|
||||
this, as the kernel name was written all upper case. However, the prefix
|
||||
is unique among kernels, and does not cause harm).
