functions only Those two functions are void sym_set_change_count(int count) and void sym_add_change_count(int count) All write accesses to sym_change_count are replaced by calls to above functions. Variable and changer-functions are moved to confdata.c. IMO thats ok, as sym_change_count is an attribute of the .config's change state.

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.

2006-10-01kconfig: fix saving alternate kconfig file in parent dirSam Ravnborg
This fixes bugzilla entry: 7182 http://bugzilla.kernel.org/show_bug.cgi?id=7182 With this patch we no longer append the directory part twice before saving the config file. This patch has been sent to Roman Zippel for review with no feedback. It is so obviously simple that this should be OK to apply it anyway. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kconfig/menuconfig: do not let ncurses clutter screen on exitSam Ravnborg
Do not initialize ncurses twice - it causes unpredicable results. My display was sometimes weird after running make menuconfig and I had to execute 'reset' to properly restore my display. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kconfig/lxdialog: clear long menu linesSam Ravnborg
Menulines that were wider than the available line width is now properly null terminated. While at it renamed the variable choice => line_y so it better reflect the usage in do_print_item(). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kbuild: do not build mconf & lxdialog unless neededSam Ravnborg
Due to a limitation in kbuild all objects referred by xxx-y or xxx-objs will be build when one of the targets needs to e build. This caused lxdialog to be build pulling in ncurses that is not always available. So avoid building mconf & lxdialog unless really needed. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2006-09-30kconfig/lxdialog: support resizeSam Ravnborg
In all dialogs now properly catch KEY_RESIZE and take proper action. In mconf try to behave sensibly when a dialog routine returns -ERRDISPLAYTOOSMALL. The original check for a screnn size of 80x19 is kept for now. It may make sense to remove it later, but thats anyway what much text is adjusted for. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kconfig/lxdialog: let <ESC><ESC> behave as expectedSam Ravnborg
<ESC><ESC> is used to step one back in the dialogs. When lxdialog became built-in pressing <ESC> once would cause one step back and pressing <ESC><ESC> would cause two steps back. This patch - based on concept from Roman Zippel <zippel@linux-m68k.org> - makes one <ESC> a noop and pressing <ESC><ESC> will cause one step backward. In addition the final yes/no dialog now has the option to go back to the the kernel configuration. So if you get too far out you can now go back to configuring the kernel without saving and starting all over again. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kconfig/menuconfig: lxdialog is now built-inSam Ravnborg
lxdialog was previously called as an external program causing screen to flicker when used. With this patch lxdialog is now built-in. It is loosly based om previous work by: Petr Baudis <pasky@ucw.cz> Following is a list of changes: o Moved build of dialog routings to kconfig Makefile o menubox + checklist uses a new item list to hold all menu items o in util.c implmented helper function to deal with item list o menubox now uses parameters to save scroll state (avoids temp file) o textbox now get text to be displayed as parameter and not a file o make sure to properly delete subwin's before main windows o killed unused files: lxdialog.c msgbox.c o modified return value for ESC to match direct calling o in a few places the code has been adjusted to 80 char wide o in textbox a small refactoring was made to make code remotely readable o in mconf removed all unused stuff (functions/variables) Following is a list of know short comings: a) pressing ESC twice will be interpreted as two ESC presses b) resize does not work. menuconfig needs to be restarted to be adjusted Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2006-09-30kconfig/lxdialog: add a new theme bluetitle which is now defaultSam Ravnborg
The bluetitle theme is a slightly modified version of the colorscheme that -mm users has been used to. The bluetitle is more readable especially on some LCD screens so it is now default. Anyone that really wants the old color selection can get it by selecting the classic color theme: make MENUCONFIG_COLOR=classic menuconfig The bluetitle theme was modified by Roman Zippel <zippel@linux-m68k.org> to further improve readability on LCD screens.

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.

2006-03-06kbuild: change kbuild to not rely on incorrect GNU make behaviorPaul Smith
The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

2006-02-27kbuild: small update of allnoconfig descriptionJesper Juhl
'allnoconfig' is described by 'make help' as a "minimal config", that's not strictly correct. To be pedantic, a minimal config would be one where EMBEDDED was set to Y and most things therein disabled etc. Simply answering 'no' to all options does not give a minimal config. A better description of allnoconfig is that it answers all options with 'no'. This patch updates the description.
