[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.

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.

[PATCH] kconfig: preset config during all*config

2005-11-09T15:55:53+00:00

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.

[PATCH] kconfig: fix restart for choice symbols

2005-11-09T15:55:53+00:00

The restart check whether new symbols became visible, didn't always work for
choice symbols.  Even if a choice symbol itself isn't changable, the childs
are.  This also requires to update the new status of all choice values, once
one of them is set.
