|
Move config options from headers to defconfig files.
|
|
|
|
Since Kconfig was introduced to U-Boot, we have worked on moving
|
|
config options from headers to Kconfig (defconfig).
|
|
|
|
This tool intends to help this tremendous work.
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
This tool takes one input file. (let's say 'recipe' file here.)
|
|
The recipe describes the list of config options you want to move.
|
|
Each line takes the form:
|
|
<config_name> <type> <default>
|
|
(the fields must be separated with whitespaces.)
|
|
|
|
<config_name> is the name of config option.
|
|
|
|
<type> is the type of the option. It must be one of bool, tristate,
|
|
string, int, and hex.
|
|
|
|
<default> is the default value of the option. It must be appropriate
|
|
value corresponding to the option type. It must be either y or n for
|
|
the bool type. Tristate options can also take m (although U-Boot has
|
|
not supported the module feature).
|
|
|
|
You can add two or more lines in the recipe file, so you can move
|
|
multiple options at once.
|
|
|
|
Let's say, for example, you want to move CONFIG_CMD_USB and
|
|
CONFIG_SYS_TEXT_BASE.
|
|
|
|
The type should be bool, hex, respectively. So, the recipe file
|
|
should look like this:
|
|
|
|
$ cat recipe
|
|
CONFIG_CMD_USB bool n
|
|
CONFIG_SYS_TEXT_BASE hex 0x00000000
|
|
|
|
Next you must edit the Kconfig to add the menu entries for the configs
|
|
you are moving.
|
|
|
|
And then run this tool giving the file name of the recipe
|
|
|
|
$ tools/moveconfig.py recipe
|
|
|
|
The tool walks through all the defconfig files to move the config
|
|
options specified by the recipe file.
|
|
|
|
The log is also displayed on the terminal.
|
|
|
|
Each line is printed in the format
|
|
<defconfig_name> : <action>
|
|
|
|
<defconfig_name> is the name of the defconfig
|
|
(without the suffix _defconfig).
|
|
|
|
<action> shows what the tool did for that defconfig.
|
|
It looks like one of the followings:
|
|
|
|
- Move 'CONFIG_... '
|
|
This config option was moved to the defconfig
|
|
|
|
- Default value 'CONFIG_...'. Do nothing.
|
|
The value of this option is the same as default.
|
|
We do not have to add it to the defconfig.
|
|
|
|
- 'CONFIG_...' already exists in Kconfig. Do nothing.
|
|
This config option is already defined in Kconfig.
|
|
We do not need/want to touch it.
|
|
|
|
- Undefined. Do nothing.
|
|
This config option was not found in the config header.
|
|
Nothing to do.
|
|
|
|
- Failed to process. Skip.
|
|
An error occurred during processing this defconfig. Skipped.
|
|
(If -e option is passed, the tool exits immediately on error.)
|
|
|
|
Finally, you will be asked, Clean up headers? [y/n]:
|
|
|
|
If you say 'y' here, the unnecessary config defines are removed
|
|
from the config headers (include/configs/*.h).
|
|
It just uses the regex method, so you should not rely on it.
|
|
Just in case, please do 'git diff' to see what happened.
|
|
|
|
|
|
How does it works?
|
|
------------------
|
|
|
|
This tool runs configuration and builds include/autoconf.mk for every
|
|
defconfig. The config options defined in Kconfig appear in the .config
|
|
file (unless they are hidden because of unmet dependency.)
|
|
On the other hand, the config options defined by board headers are seen
|
|
in include/autoconf.mk. The tool looks for the specified options in both
|
|
of them to decide the appropriate action for the options. If the option
|
|
is found in the .config or the value is the same as the specified default,
|
|
the option does not need to be touched. If the option is found in
|
|
include/autoconf.mk, but not in the .config, and the value is different
|
|
from the default, the tools adds the option to the defconfig.
|
|
|
|
For faster processing, this tool handles multi-threading. It creates
|
|
separate build directories where the out-of-tree build is run. The
|
|
temporary build directories are automatically created and deleted as
|
|
needed. The number of threads are chosen based on the number of the CPU
|
|
cores of your system although you can change it via -j (--jobs) option.
|
|
|
|
|
|
Toolchains
|
|
----------
|
|
|
|
Appropriate toolchain are necessary to generate include/autoconf.mk
|
|
for all the architectures supported by U-Boot. Most of them are available
|
|
at the kernel.org site, some are not provided by kernel.org.
|
|
|
|
The default per-arch CROSS_COMPILE used by this tool is specified by
|
|
the list below, CROSS_COMPILE. You may wish to update the list to
|
|
use your own. Instead of modifying the list directly, you can give
|
|
them via environments.
|
|
|
|
|
|
Available options
|
|
-----------------
|
|
|
|
-c, --color
|
|
Surround each portion of the log with escape sequences to display it
|
|
in color on the terminal.
|
|
|
|
-d, --defconfigs
|
|
Specify a file containing a list of defconfigs to move
|
|
|
|
-n, --dry-run
|
|
Peform a trial run that does not make any changes. It is useful to
|
|
see what is going to happen before one actually runs it.
|
|
|
|
-e, --exit-on-error
|
|
Exit immediately if Make exits with a non-zero status while processing
|
|
a defconfig file.
|
|
|
|
-H, --headers-only
|
|
Only cleanup the headers; skip the defconfig processing
|
|
|
|
-j, --jobs
|
|
Specify the number of threads to run simultaneously. If not specified,
|
|
the number of threads is the same as the number of CPU cores.
|
|
|
|
-v, --verbose
|
|
Show any build errors as boards are built
|
|
|
|
To see the complete list of supported options, run
|
|
|
|
$ tools/moveconfig.py -h
