kconfig: correct oldconfig for unset choice options

2006-08-01T09:32:47Z

oldconfig currently ignores unset choice options and doesn't ask for them. Correct the SYMBOL_DEF_USER flag of the choice symbol to be only set if it's set for all values. Signed-off-by: Roman Zippel Signed-off-by: Sam Ravnborg

kconfig: KCONFIG_OVERWRITECONFIG

2006-06-09T14:28:07Z

If you set KCONFIG_OVERWRITECONFIG in environment, Kconfig will not break symlinks when .config is a symlink to somewhere else. Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: add defconfig_list/module option

2006-06-09T05:31:30Z

This makes it possible to change two options which were hardcoded sofar. 1. Any symbol can now take the role of CONFIG_MODULES 2. The more useful option is to change the list of default file names, which kconfig uses to load the base configuration if .config isn't available.

kconfig: integrate split config into silentoldconfig

2006-06-09T05:31:30Z

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).

kconfig: allow loading multiple configurations

2006-06-09T05:31:30Z

Extend conf_read_simple() so it can load multiple configurations. Signed-off-by: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: allow multiple default values per symbol

2006-06-09T05:31:30Z

Extend struct symbol to allow storing multiple default values, which can be used to hold multiple configurations. Signed-off-by: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: fix .config dependencies

2006-06-09T05:31:30Z

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.

kconfig: improve config load/save output

2006-06-09T05:31:30Z

During loading special case the first common case (.config), be silent about it and otherwise mark it as a change that requires saving. Instead output that the file has been changed. IOW if conf does nothing (special), it's silent. Signed-off-by: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: fix typo in change count initialization

2006-04-11T11:41:06Z

Configuration needs saving when either of these conditions is true. Signed-off-by: Roman Zippel Signed-off-by: Sam Ravnborg

kconfig: fix time ordering of writes to .kconfig.d and include/linux/autoconf.h

2006-03-12T22:38:20Z

Since .kconfig.d is used as a make dependency of include/linux/autoconf.h, it should be written earlier than the header file, to avoid a subsequent rebuild to consider the header outdated. Signed-Off-By: Jan Beulich Signed-off-by: Sam Ravnborg
