2009-03-15kconfig: fix randconfig for choice blocksSam Ravnborg
Ingo Molnar reported that 'make randconfig' was not covering choice blocks properly, resulting in certain config options being left out of randconfig testing altogether. With the following patch we: - properly randomize choice value for normal choice blocks - properly randomize for multi choice blocks - added several comments to explain what is going on The root cause of the bug was that SYMBOL_VALID was set on the symbol representing the choice block so clearing this did the trick initially. But testign revealed a few more issues that is now fixed.

2008-10-26fix allmodconfig breakageAl Viro
If you use KCONFIG_ALLCONFIG (even with empty file) you get broken allmodconfig/allyesconfig; CONFIG_MODULES gets turned off, with obvious massive fallout. Breakage had been introduced when conf_set_all_new_symbols() got used for allmodconfig et.al. What happens is that sym_calc_value(modules_sym) done in conf_read_simple() sets SYMBOL_VALID on both modules_sym and MODULES. When we get to conf_set_all_new_symbols(), we set sym->def[S_DEF_USER] on everything, but it has no effect on sym->curr for the symbols that already have SYMBOL_VALID - these are stuck. Solution: use sym_clear_all_valid() in there. Note that it makes reevaluation of modules_sym redundant - sym_clear_all_valid() will do that itself.

Commit f072181e6403b0fe2e2aa800a005497b748fd284 ("kconfig: drop the ""trying to assign nonexistent symbol" warning") simply dropped the warnings, but it does a little more than that, it also marks the current .config as needed saving, so add this back.

2008-01-28kconfig: allow overriding symbolsJan Engelhardt
Allow config variables in .config to override earlier ones in the same file. In other words, # CONFIG_SECURITY is not defined CONFIG_SECURITY=y will activate it.

2007-11-17x86: simplify "make ARCH=x86" and fix kconfig all.configSam Ravnborg
Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in all.config. For a fix the diffstat is nice: 6 files changed, 3 insertions(+), 36 deletions(-) The patch reverts these commits: - 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set config symbol from environment variable") - 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to set 64BIT with all*config targets") Roman Zippel pointed out that kconfig supported string compares so the additional complexity introduced by the above two patches were not needed. With this patch we have following behaviour: # make {allno,allyes,allmod,rand}config [ARCH=...] option \ host arch | 32bit | 64bit ===================================================== ./. | 32bit | 64bit ARCH=x86 | 32bit | 32bit ARCH=i386 | 32bit | 32bit ARCH=x86_64 | 64bit | 64bit The general rule are that ARCH= and native architecture takes precedence over the configuration. So make ARCH=i386 [whatever] will always build a 32-bit kernel no matter what the configuration says. The configuration will be updated to 32-bit if it was configured to 64-bit and the other way around. This behaviour is consistent with previous behaviour so no suprises here. make ARCH=x86 will per default result in a 32-bit kernel but as the only ARCH= value x86 allow the user to select between 32-bit and 64-bit using menuconfig.

2007-07-17kconfig: reset generated values only if Kconfig and .config agree.Roman Zippel
Normally generated values (Kconfig entries without a prompt) are cleared as they are regenerated anyway and so they appear as new should they become visible and defaults work as expected (once a value is set defaults aren't used anymore). The detection whether a value is generated or not is only based on its visibility status, which can quickly change for a lot of symbols by just removing a single line from .config or adding a dependency to Kconfig as you noticed. The patch now suppresses this logic when .config and Kconfig aren't in sync and .config needs to be updated, so that you can remove now a random value from .config and oldconfig won't reask for many other values.

2006-12-13[PATCH] kconfig: new function "bool conf_get_changed(void)"Karsten Wiese
Run "make xconfig" on a freshly untarred kernel-tree. Look at the floppy disk icon of the qt application, that has just started: Its in a normal, active state. Mouse click on it: .config is being saved. This patch series changes things so taht after the mouse click on the floppy disk icon, the icon is greyed out. If you mouse click on it now, nothing happens. If you change some CONFIG_*, the floppy disk icon returns to "active state", that is, if you mouse click it now, .config is written. This patch: Returns sym_change_count to reflect the .config's change state. All read only accesses of sym_change_count are replaced by calls to conf_get_changed() . mconfig.c is manipulated to ask for saving only when conf_get_changed() returned true.

Kconfig doesn't currently handle config files with DOS line endings. While these are, of course, an abomination, etc, etc, it can be handy to not have to convert them first.

2006-06-09kconfig: integrate split config into silentoldconfigRoman Zippel
Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

2006-06-09kconfig: fix .config dependenciesRoman Zippel
This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

Allow to force setting of config variables during all{no,mod,yes,random}config to a specific value. For that conf first checks the KCONFIG_ALLCONFIG environment variable for a file name, otherwise it checks for all{no,mod,yes,random}.config and all.config. The file is a normal config file, which presets the config variables, but they are still subject to normal dependency checks.

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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
