* kconfig: environment symbol supportRoman Zippel2008-01-28
| | | | | | | | | | Add the possibility to import a value from the environment into kconfig via the option syntax. Beside flexibility this has the advantage providing proper dependencies. Documented the options syntax. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: explicitly introduce expression listRoman Zippel2008-01-28
| | | | | | | | | Rename E_CHOICE to E_LIST to explicitly add support for expression lists. Add a helper macro expr_list_for_each_sym to more easily iterate over the list. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: delete unused FILE_ and SYMBOL_ flagsSam Ravnborg2008-01-28
| | | | | | | | The *_PRINTED flags were never used - so delete them. Do we need them later then we can re-add them. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
* kconfig: rename E_OR & friends to avoid name clashSam Ravnborg2008-01-28
| | | | | | | | | We had macros named the same as a set of enumeration values. It is legal code but very confusing to read - so rename the macros from E_* to EXPR_* Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

| | | | | | | dep and dep2 in struct symbol was unused - remove them. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

This patch does this and at the same time introduce a few API funtions used to access the help text. The relevant api functions are introduced in the various frontends.

* kconfig: add defconfig_list/module optionRoman Zippel2006-06-09
| | | | | | | | | | | | 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 silentoldconfigRoman Zippel2006-06-09
| | | | | | | | | | | | | 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: remove SYMBOL_{YES,MOD,NO}Roman Zippel2006-06-09
| | | | | | | | | The SYMBOL_{YES,MOD,NO} are not really used anymore (they were more used be the cml1 converter), so just remove them. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* [PATCH] kconfig: Fix Kconfig performance bugDavid Gibson2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | When doing its recursive dependency check, scripts/kconfig/conf uses the flag SYMBOL_CHECK_DONE to avoid rechecking a symbol it has already checked. However, that flag is only set at the top level, so if a symbol is first encountered as a dependency of another symbol it will be rechecked every time it is encountered until it's encountered at the top level. This patch adjusts the flag setting so that each symbol will only be checked once, regardless of whether it is first encountered at the top level, or while recursing down from another symbol. On complex configurations, this vastly speeds up scripts/kconfig/conf. The config in the powerpc merge tree is particularly bad: this patch reduces the time for 'scripts/kconfig/conf -o arch/powerpc/Kconfig' by a factor of 40 on a G5. That's even including the time to print the config, so the speedup in the actual checking is more likely 2 or 3 orders of magnitude.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
