2013-06-24kconfig: loop as long as we changed some symbols in randconfigYann E. MORIN
Because of choice-in-a-choice constructs, it can happen that not all symbols are assigned a value during randconfig, leading in rare cases to this situation: ---8<--- choice-in-choice.in choice bool "A/B/C" config A bool "A" config B bool "B" if B choice bool "E/F" config E bool "E" config F bool "F" endchoice endif # B config C bool "C" endchoice ---8<--- $ ./scripts/kconfig/conf --randconfig choice-in-choice.in [--SNIP--] $ ./scripts/kconfig/conf --silentoldconfig choice-in-choice.in </dev/null [--SNIP--] A/B/C 1. A (A) > 2. B (B) 3. C (C) choice[1-3]: 2 E/F > 1. E (E) (NEW) 2. F (F) (NEW) choice[1-2]: aborted! Console input/output is redirected. Run 'make oldconfig' to update configuration. Fix this by looping in randconfig for as long as some symbol gets assigned a value. Note: this was spotted with the USB EHCI Debug Device Gadget (USB_G_DBGP), which uses this choice-in-a-choice construct, and exhibits this problem. The example above is just a stripped-down minimalist test-case. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

2012-11-20kconfig: get CONFIG_ prefix from the environmentYann E. MORIN
Currently, the CONFIG_ prefix is hard-coded in the kconfig frontends executables. This means that two projects that use kconfig with different prefixes can not share the same kconfig frontends. Instead of hard-coding the prefix in the frontends, get it from the environment, and revert back to hard-coded value if not found. Signed-off-by: "Yann E.

2012-11-20kconfig: add a function to get the CONFIG_ prefixYann E. MORIN
Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means the CONFIG_ prefix is hard-coded at compile time. This goes against having a run-time defined CONFIG_ prefix. Add a function that returns the CONFIG_ prefix to use (but keep the current hard-coded behavior, to be changed in a later patch). To avoid touching all the code that uses the CONFIG_ macro, we just undef it, and define it to be a call to the function. Signed-off-by: "Yann E.

2012-01-15kbuild: Fix compiler warning with assertion when calling 'fwrite'Arnaud Lacombe
Reinhard Tartler discovered a corner case of calling xfwrite() where the length of the string is zero. Arnaud Lacombe suggested to use assertion for the corner case, as fwrite(3) is currently used: 1) in comment printers. Empty comment are not allowed. 2) in a callback passed to expr_print(), where the string printed is either NULL OR non-empty. 3) in the lexer, auto-generated, and unused. I feel using assertion is a good solution: 1) It cleanly takes care of the above-mentioned corner case. 2) It can be easily disabled by defining NDEBUG. 3) It asserts xfwrite() is simply a wrapper for fwrite().

2010-08-03kconfig: add savedefconfigSam Ravnborg
savedefconfig will save a minimal config to a file named "defconfig". The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.

2010-02-02menuconfig: wrap long help linesVadim Bendebury (вб)
Help text for certain config options is very extensive (the text includes the names of all other options the option in question depends on). Long lines are not wrapped, making it impossible to see the list without scrolling horizontally. This patch adds some logic which wraps help screen lines at word boundaries to prevent truncating. Tested by running ARCH=powerpc make menuconfig O=/tmp/build which shows that the long lines are now wrapped, and ARCH=powerpc make xconfig O=/tmp/build to demonstrate that it still compiles and operates as expected.

2005-05-05[PATCH] Kconfig i18n supportArnaldo Carvalho de Melo
This patch adds i18n support for make *config, allowing users to have the config process in their own language. No printk was harmed in the process, don't worry, so all the bug reports, kernel messages, etc, remain in english, just the user tools to configure the kernel are internationalized. Users not interested in translations can just unset the related LANG, LC_ALL, etc env variables and have the config process in plain english, something like: LANG= make menuconfig is enough for having the whole config process in english. Or just don't install any translation file. Translations for brazilian portuguese are being done by a team of volunteers at: http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes To start the translation process: make update-po-config This will generate the pot template named scripts/kconfig/linux.pot, copy it to, say, ~/es.po, to start the translation for spanish. To test your translation, as root issue this command: msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po Replace "es" with your language code. Then execute, for instance: make menuconfig The current patch doesn't use any optimization to reduce the size of the generated .mo file, it is possible to use the config option as a key, but this doesn't prevent the current patch from being used or the translations done under the current scheme to be in any way lost if we chose to do any kind of keying. Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese) translation effort, Thiago Maciera for helping me with the gconf.cc (QT frontent) i18n coding and to all the volunteers that are already working on the first translation, to pt_BR.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
