kconfig: oldconfig shall not set symbols if it does not need to

2007-09-26T17:54:37+00:00

commit f82f3f9422d4da1eeec6f6cf3e64c6c34c4fe19b in mainline. Avoid setting the value if the symbol doesn't need to be changed or can't be changed. Later choices may change the dependencies and thus the possible input range. make oldconfig from a 2.6.22 .config with CONFIG_HOTPLUG_CPU not set was in some configurations setting CONFIG_HOTPLUG_CPU=y without asking, even when there was no actual requirement for CONFIG_HOTPLUG_CPU. This was triggered by SUSPEND_SMP that does a select HOTPLUG_CPU. Signed-off-by: Roman Zippel Tested-by: Hugh Dickins Signed-off-by: Sam Ravnborg Signed-off-by: Greg Kroah-Hartman

kbuild: be more explicit on missing .config file

2007-05-02T18:58:11+00:00

Somewhat in reponse to kernel bugzilla #8197, be more explicit about why 'make all' fails when there is no .config file. Signed-off-by: Randy Dunlap Signed-off-by: Sam Ravnborg

[PATCH] kconfig: new function "bool conf_get_changed(void)"

2006-12-13T17:05:48+00:00

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: exit if no beginning filename

2006-06-09T14:28:07+00:00

If the beginning Kconfig file is missing, config segfaults so it might as well exit after the error message. Signed-off-by: Randy Dunlap Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: fix .config dependencies

2006-06-09T05:31:30+00:00

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.
