2008-02-13kconfig: fix select in combination with defaultRoman Zippel1-13/+21
> The attached .config (with current -git) results in a compile > error since it contains: > > CONFIG_X86=y > # CONFIG_EMBEDDED is not set > CONFIG_SERIO=m > CONFIG_SERIO_I8042=y > > Looking at drivers/input/serio/Kconfig I simply don't get how this > can happen. You've hit the rather subtle rules of select vs default. What happened is that SERIO is selected to m, but SERIO_I8042 isn't selected so the default of y is used instead. We already had the problem in the past that select and default don't work well together, so this patch cleans this up and makes the rule hopefully more straightforward. Basically now the value is calculated like this: (value && dependency) || select where the value is the user choice (if available and the symbol is visible) or default. In this case it means SERIO and SERIO_I8042 are both set to y due to their default and if SERIO didn't had the default, then the SERIO_I8042 value would be limited to m due to the dependency. I tested this patch with more 10000 random configs and above case is the only the difference that showed up, so I hope there is nothing that depended on the old more complex and subtle rules.

2008-02-03kconfig: ignore select of unknown symbolSam Ravnborg1-6/+3
We have had warnings for a long time about select of unknow symbol but the warnings does not really makes sense since we may select a symbol that is relevant and defined in one arch but not in another arch. And as long as we do not use a common set of Kconfig files for all archs lets just ignore this case. Previously we have used this to find bad uses of select but we need a more relaible method to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>

Change kconfig behavior so that mixing bool and tristate config settings in a choice is possible and has the desired effect of offering just the tristate options individually if the choice gets set to M, and a normal boolean selection if the choice gets set to Y. Also fix scripts/kconfig/conf's handling of children of choice values - there may be more than one immediate child, and all of them need to be processed.

2008-01-28kconfig: make kconfig MinGW friendlyLadislav Michl3-66/+32
Kconfig is powerfull tool. So powerfull that more and more software projects are using it for configuration. So instead of fixing some of them one by one, lets fix it in kernel and wait for sync. This work was originaly done for PTXdist - GPL licensed build system for userlands and cross-compilers, but it will not hurt kernel kconfig either. PTXdist menuconfig now works on Windows linked with PDCurses and compiled using MinGW - there is no termios and signals. * Do not include <sys/wait.h> and <signal.h> (comes from times when lxdialog was separate process) * Do not mess with termios directly and let curses tell screen size. Comment to commit c8dc68ad0fbd934e78e913b8a8d7b45945db4930 says check for screen size could be removed later, but because it didn't happen for more than year I left it here as well. * Save cursor position added by Sam Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
2008-01-28kconfig: use getopt() in conf.c for handling command line argumentsAndres Salomon1-13/+11
Switch from doing our own parsing of command line arguments to using getopt(3) to do it. Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no compatibility checking amongst arguments; the last option will simply override earlier options. For example, 'conf -n -y foo' is perfectly valid now (input_mode will be set_yes). Previously, that would have been an error ("can't find file -y").

2007-11-17x86: simplify "make ARCH=x86" and fix kconfig all.configSam Ravnborg3-29/+0
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.

This is for example useful for powerpc to generate allmodconfig for both bit sizes - like this: make ARCH=powerpc K64BIT=y make ARCH=powerpc K64BIT=n To use this the Kconfig file must use "64BIT" as the config value to select between 32 and 64 bit.

2007-10-19Revert "kconfig: tristate choices with mixed tristate and boolean values"Linus Torvalds1-26/+9
This reverts commit a5bf3d891a6a0fb5aa122792d965e3774108b923. David Brownell notes that this causes a regression visible in the drivers/usb/gadget Kconfig file: "That Kconfig hasn't changed (other than adding new drivers), and it's worked that way for several years now ... so the issue seems to be changes in menuconfig/kconfig/etc semantics. The issue is that when USB_GADGET=m, it's no longer possible to configure peripheral controller drivers as modules ... the controller drivers can now only be configured for static linkage. It should be making a choice of one of the controller drivers which could work on the target system, and allow that driver to be linked either as a module (ok iff USB_GADGET=m) or statically." Reverting this commit resolves the problem, and also fixes a second problem that David noticed: various dependent options couldn't be enabled.

2007-10-12kconfig/menuconfig: distinguish between selected-by-another options and commentsMatej Laitl1-8/+15
menuconfig currently represents options implied by another option ('select' directive in Kconfig) by prefixing them with '---'. Unfortunately the same notation is used for comments. If the implied option is module capable, user can still switch between Y and M, all without any feedback until she visits option's help. (try saying M to MAC80211 and then toggling CFG80211) This patch changes notation of selected-by-another items by introducing 2 new representations for implied options: {*} or {M} for options selected by another modularized one, thus builtin or module capable, -*- or -M- for options that cannot be at the moment changed by user. The idea is to represent actual capability of the option by braces (dashes) around and to always report actual state by * or M inside.

2007-07-17kconfig: reset generated values only if Kconfig and .config agree.Roman Zippel1-11/+26
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.

2007-07-17kconfig: strip 'CONFIG_' automatically in kernel configuration searchBernhard Walle1-2/+9
Modify the ncurses configuration tool ('make menuconfig') in a way that the user can enter the search string (/) both with or without the leading 'CONFIG_'. This simplifies using copy & paste from .config files because you can select the whole word.
