x86: simplify "make ARCH=x86" and fix kconfig all.config

2007-11-17T16:35:43Z

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.

kconfig: add helper to set config symbol from environment variable

2007-11-12T20:02:20Z

Add conf_set_env_sym() that can set an already defined symbol based on the value of an environment variable. Unknown symbols are silently ignored. A warning is printed if the value of the environment variable is unexpected. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: reset generated values only if Kconfig and .config agree.

2007-07-17T12:24:55Z

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.

[PATCH] kconfig: add "void conf_set_changed_callback(void (*fn)(void))", use it in qconf.cc

2006-12-13T17:05:48Z

Added function sets "void (*conf_changed_callback)(void)". Call it, if .config's changed state changes. Use above in qconf.cc to set gui's save-widget's sensitvity.

[PATCH] kconfig: make sym_change_count static, let it be altered by 2 functions only

2006-12-13T17:05:48Z

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.

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

2006-12-13T17:05:48Z

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: fix saving alternate kconfig file in parent dir

2006-10-01T09:48:53Z

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

kconfig: support DOS line endings

2006-09-25T07:00:00Z

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. It's also a tiny patch and even adds support for lines ending in just \r or even \n\r. Signed-off-by: Matthew Wilcox Signed-off-by: Sam Ravnborg

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
