Now that we are using absolute paths we can remove some of the sys.path mangling that appears in the tools. We only need to add the path to 'tools/' so that everything can find modules relative to that directory. The special paths for finding pylibfdt remain. Signed-off-by: Simon Glass <sjg@chromium.org>

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
|
|
-----
|
|
|
|
First, you must edit the Kconfig to add the menu entries for the configs
|
|
you are moving.
|
|
|
|
And then run this tool giving CONFIG names you want to move.
|
|
For example, if you want to move CONFIG_CMD_USB and CONFIG_SYS_TEXT_BASE,
|
|
simply type as follows:
|
|
|
|
$ tools/moveconfig.py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE
|
|
|
|
The tool walks through all the defconfig files and move the given CONFIGs.
|
|
|
|
The log is also displayed on the terminal.
|
|
|
|
The log is printed for each defconfig as follows:
|
|
|
|
<defconfig_name>
|
|
<action1>
|
|
<action2>
|
|
<action3>
|
|
...
|
|
|
|
<defconfig_name> is the name of the defconfig.
|
|
|
|
<action*> shows what the tool did for that defconfig.
|
|
It looks like one of the following:
|
|
|
|
- Move 'CONFIG_... '
|
|
This config option was moved to the defconfig
|
|
|
|
- CONFIG_... is not defined in Kconfig. Do nothing.
|
|
The entry for this CONFIG was not found in Kconfig. The option is not
|
|
defined in the config header, either. So, this case can be just skipped.
|
|
|
|
- CONFIG_... is not defined in Kconfig (suspicious). Do nothing.
|
|
This option is defined in the config header, but its entry was not found
|
|
in Kconfig.
|
|
There are two common cases:
|
|
- You forgot to create an entry for the CONFIG before running
|
|
this tool, or made a typo in a CONFIG passed to this tool.
|
|
- The entry was hidden due to unmet 'depends on'.
|
|
The tool does not know if the result is reasonable, so please check it
|
|
manually.
|
|
|
|
- 'CONFIG_...' is the same as the define in Kconfig. Do nothing.
|
|
The define in the config header matched the one in Kconfig.
|
|
We do not need to touch it.
|
|
|
|
- Compiler is missing. Do nothing.
|
|
The compiler specified for this architecture was not found
|
|
in your PATH environment.
|
|
(If -e option is passed, the tool exits immediately.)
|
|
|
|
- Failed to process.
|
|
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 work?
|
|
-----------------
|
|
|
|
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 given
|
|
config option is found in the .config, but its value does not match the
|
|
one from the board header, the config option in the .config is replaced
|
|
with the define in the board header. Then, the .config is synced by
|
|
"make savedefconfig" and the defconfig is updated with it.
|
|
|
|
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. This tool uses
|
|
the same tools as buildman, so see that tool for setup (e.g. --fetch-arch).
|
|
|
|
|
|
Tips and trips
|
|
--------------
|
|
|
|
To sync only X86 defconfigs:
|
|
|
|
./tools/moveconfig.py -s -d <(grep -l X86 configs/*)
|
|
|
|
or:
|
|
|
|
grep -l X86 configs/* | ./tools/moveconfig.py -s -d -
|
|
|
|
To process CONFIG_CMD_FPGAD only for a subset of configs based on path match:
|
|
|
|
ls configs/{hrcon*,iocon*,strider*} | \
|
|
./tools/moveconfig.py -Cy CONFIG_CMD_FPGAD -d -
|
|
|
|
|
|
Finding implied CONFIGs
|
|
-----------------------
|
|
|
|
Some CONFIG options can be implied by others and this can help to reduce
|
|
the size of the defconfig files. For example, CONFIG_X86 implies
|
|
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
|
|
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
|
|
each of the x86 defconfig files.
|
|
|
|
This tool can help find such configs. To use it, first build a database:
|
|
|
|
./tools/moveconfig.py -b
|
|
|
|
Then try to query it:
|
|
|
|
./tools/moveconfig.py -i CONFIG_CMD_IRQ
|
|
CONFIG_CMD_IRQ found in 311/2384 defconfigs
|
|
44 : CONFIG_SYS_FSL_ERRATUM_IFC_A002769
|
|
41 : CONFIG_SYS_FSL_ERRATUM_A007075
|
|
31 : CONFIG_SYS_FSL_DDR_VER_44
|
|
28 : CONFIG_ARCH_P1010
|
|
28 : CONFIG_SYS_FSL_ERRATUM_P1010_A003549
|
|
28 : CONFIG_SYS_FSL_ERRATUM_SEC_A003571
|
|
28 : CONFIG_SYS_FSL_ERRATUM_IFC_A003399
|
|
25 : CONFIG_SYS_FSL_ERRATUM_A008044
|
|
22 : CONFIG_ARCH_P1020
|
|
21 : CONFIG_SYS_FSL_DDR_VER_46
|
|
20 : CONFIG_MAX_PIRQ_LINKS
|
|
20 : CONFIG_HPET_ADDRESS
|
|
20 : CONFIG_X86
|
|
20 : CONFIG_PCIE_ECAM_SIZE
|
|
20 : CONFIG_IRQ_SLOT_COUNT
|
|
20 : CONFIG_I8259_PIC
|
|
20 : CONFIG_CPU_ADDR_BITS
|
|
20 : CONFIG_RAMBASE
|
|
20 : CONFIG_SYS_FSL_ERRATUM_A005871
|
|
20 : CONFIG_PCIE_ECAM_BASE
|
|
20 : CONFIG_X86_TSC_TIMER
|
|
20 : CONFIG_I8254_TIMER
|
|
20 : CONFIG_CMD_GETTIME
|
|
19 : CONFIG_SYS_FSL_ERRATUM_A005812
|
|
18 : CONFIG_X86_RUN_32BIT
|
|
17 : CONFIG_CMD_CHIP_CONFIG
|
|
...
|
|
|
|
This shows a list of config options which might imply CONFIG_CMD_EEPROM along
|
|
with how many defconfigs they cover. From this you can see that CONFIG_X86
|
|
implies CONFIG_CMD_EEPROM. Therefore, instead of adding CONFIG_CMD_EEPROM to
|
|
the defconfig of every x86 board, you could add a single imply line to the
|
|
Kconfig file:
|
|
|
|
config X86
|
|
bool "x86 architecture"
|
|
...
|
|
imply CMD_EEPROM
|
|
|
|
That will cover 20 defconfigs. Many of the options listed are not suitable as
|
|
they are not related. E.g. it would be odd for CONFIG_CMD_GETTIME to imply
|
|
CMD_EEPROM.
|
|
|
|
Using this search you can reduce the size of moveconfig patches.
|
|
|
|
You can automatically add 'imply' statements in the Kconfig with the -a
|
|
option:
|
|
|
|
./tools/moveconfig.py -s -i CONFIG_SCSI \
|
|
-a CONFIG_ARCH_LS1021A,CONFIG_ARCH_LS1043A
|
|
|
|
This will add 'imply SCSI' to the two CONFIG options mentioned, assuming that
|
|
the database indicates that they do actually imply CONFIG_SCSI and do not
|
|
already have an 'imply SCSI'.
|
|
|
|
The output shows where the imply is added:
|
|
|
|
18 : CONFIG_ARCH_LS1021A arch/arm/cpu/armv7/ls102xa/Kconfig:1
|
|
13 : CONFIG_ARCH_LS1043A arch/arm/cpu/armv8/fsl-layerscape/Kconfig:11
|
|
12 : CONFIG_ARCH_LS1046A arch/arm/cpu/armv8/fsl-layerscape/Kconfig:31
|
|
|
|
The first number is the number of boards which can avoid having a special
|
|
CONFIG_SCSI option in their defconfig file if this 'imply' is added.
|
|
The location at the right is the Kconfig file and line number where the config
|
|
appears. For example, adding 'imply CONFIG_SCSI' to the 'config ARCH_LS1021A'
|
|
in arch/arm/cpu/armv7/ls102xa/Kconfig at line 1 will help 18 boards to reduce
|
|
the size of their defconfig files.
|
|
|
|
If you want to add an 'imply' to every imply config in the list, you can use
|
|
|
|
./tools/moveconfig.py -s -i CONFIG_SCSI -a all
|
|
|
|
To control which ones are displayed, use -I <list> where list is a list of
|
|
options (use '-I help' to see possible options and their meaning).
|
|
|
|
To skip showing you options that already have an 'imply' attached, use -A.
|
|
|
|
When you have finished adding 'imply' options you can regenerate the
|
|
defconfig files for affected boards with something like:
|
|
|
|
git show --stat | ./tools/moveconfig.py -s -d -
|
|
|
|
This will regenerate only those defconfigs changed in the current commit.
|
|
If you start with (say) 100 defconfigs being changed in the commit, and add
|
|
a few 'imply' options as above, then regenerate, hopefully you can reduce the
|
|
number of defconfigs changed in the commit.
|
|
|
|
|
|
Available options
|
|
-----------------
|
|
|
|
-c, --color
|
|
Surround each portion of the log with escape sequences to display it
|
|
in color on the terminal.
|
|
|
|
-C, --commit
|
|
Create a git commit with the changes when the operation is complete. A
|
|
standard commit message is used which may need to be edited.
|
|
|
|
-d, --defconfigs
|
|
Specify a file containing a list of defconfigs to move. The defconfig
|
|
files can be given with shell-style wildcards. Use '-' to read from stdin.
|
|
|
|
-n, --dry-run
|
|
Perform 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.
|
|
|
|
-s, --force-sync
|
|
Do "make savedefconfig" forcibly for all the defconfig files.
|
|
If not specified, "make savedefconfig" only occurs for cases
|
|
where at least one CONFIG was moved.
|
|
|
|
-S, --spl
|
|
Look for moved config options in spl/include/autoconf.mk instead of
|
|
include/autoconf.mk. This is useful for moving options for SPL build
|
|
because SPL related options (mostly prefixed with CONFIG_SPL_) are
|
|
sometimes blocked by CONFIG_SPL_BUILD ifdef conditionals.
|
|
|
|
-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.
|
|
|
|
-r, --git-ref
|
|
Specify the git ref to clone for building the autoconf.mk. If unspecified
|
|
use the CWD. This is useful for when changes to the Kconfig affect the
|
|
default values and you want to capture the state of the defconfig from
|
|
before that change was in effect. If in doubt, specify a ref pre-Kconfig
|
|
changes (use HEAD if Kconfig changes are not committed). Worst case it will
|
|
take a bit longer to run, but will always do the right thing.
|
|
|
|
-v, --verbose
|
|
Show any build errors as boards are built
|
|
|
|
-y, --yes
|
|
Instead of prompting, automatically go ahead with all operations. This
|
|
includes cleaning up headers, CONFIG_SYS_EXTRA_OPTIONS, the config whitelist
|
|
and the README.
|
|
|
|
To see the complete list of supported options, run
|
|
|
|
$ tools/moveconfig.py -h

"""Find CONFIG options which imply those in the list
|
|
|
|
Some CONFIG options can be implied by others and this can help to reduce
|
|
the size of the defconfig files. For example, CONFIG_X86 implies
|
|
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
|
|
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
|
|
each of the x86 defconfig files.
|
|
|
|
This function uses the moveconfig database to find such options. It
|
|
displays a list of things that could possibly imply those in the list.
|
|
The algorithm ignores any that start with CONFIG_TARGET since these
|
|
typically refer to only a few defconfigs (often one). It also does not
|
|
display a config with less than 5 defconfigs.
|
|
|
|
The algorithm works using sets. For each target config in config_list:
|
|
- Get the set 'defconfigs' which use that target config
|
|
- For each config (from a list of all configs):
|
|
- Get the set 'imply_defconfig' of defconfigs which use that config
|
|
-
|
|
- If imply_defconfigs contains anything not in defconfigs then
|
|
this config does not imply the target config
|
|
|
|
Params:
|
|
config_list: List of CONFIG options to check (each a string)
|
|
add_imply: Automatically add an 'imply' for each config.
|
|
imply_flags: Flags which control which implying configs are allowed
|
|
(IMPLY_...)
|
|
skip_added: Don't show options which already have an imply added.
|
|
check_kconfig: Check if implied symbols already have an 'imply' or
|
|
'select' for the target config, and show this information if so.
|
|
find_superset: True to look for configs which are a superset of those
|
|
already found. So for example if CONFIG_EXYNOS5 implies an option,
|
|
but CONFIG_EXYNOS covers a larger set of defconfigs and also
|
|
implies that option, this will drop the former in favour of the
|
|
latter. In practice this option has not proved very used.
|
|
|
|
Note the terminoloy:
|
|
config - a CONFIG_XXX options (a string, e.g. 'CONFIG_CMD_EEPROM')
|
|
defconfig - a defconfig file (a string, e.g. 'configs/snow_defconfig')
