2011-06-06kconfig: nuke LKC_DIRECT_LINK cruftArnaud Lacombe
This interface is not (and has never been ?) used by any frontend, just get rid of it. Signed-off-by: Arnaud Lacombe <lacombar@gmail.com>
2010-12-21kconfig: Make expr_copy() take a const argumentMichal Marek
Fixes scripts/kconfig/expr.c: In function ‘expr_get_leftmost_symbol’: scripts/kconfig/expr.c:1026:2: warning: passing argument 1 of ‘expr_copy’ discards qualifiers from pointer target type scripts/kconfig/expr.c:67:14: note: expected ‘struct expr *’ but argument is of type ‘const struct expr *’ Signed-off-by: Michal Marek <mmarek@suse.cz>
2010-12-21kconfig: simplify select-with-unmet-direct-dependency warningArnaud Lacombe
This is an attempt to simplify the expressing printed by kconfig when a symbol is selected but still has direct unmet dependency. First, the symbol reverse dependency is split in sub-expression. Then, each sub-expression is checked to ensure that it does not contains the unmet dependency. This removes the false-positive symbols and fixed symbol which already have the correct dependency. Finally, only the symbol responsible of the "select" is printed, instead of its full dependency tree.

2010-08-13kconfig: Fix warning: ignoring return value of 'fwrite'Jean Sacren
This fix facilitates fwrite() in both confdata.c and expr.c, either it succeeds in writing, or an error occurs, or the end of file is reached. Signed-off-by: Jean Sacren <sakiwit@gmail.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
2010-06-02kconfig: print the range of integer/hex symbol in help textLi Zefan
Without this patch, one has to refer to the Kconfig file to find out the range of an integer/hex symbol. │ Symbol: NR_CPUS [=4] │ Type : integer │ Range : [2 8] │ Prompt: Maximum number of CPUs │ Defined at arch/x86/Kconfig:761 │ Depends on: SMP [=y] && !MAXSMP [=n] │ Location: │ -> Processor type and features Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
2010-02-02menuconfig: wrap long help linesVadim Bendebury (вб)
Help text for certain config options is very extensive (the text includes the names of all other options the option in question depends on). Long lines are not wrapped, making it impossible to see the list without scrolling horizontally. This patch adds some logic which wraps help screen lines at word boundaries to prevent truncating. Tested by running ARCH=powerpc make menuconfig O=/tmp/build which shows that the long lines are now wrapped, and ARCH=powerpc make xconfig O=/tmp/build to demonstrate that it still compiles and operates as expected.

2009-09-20kconfig: add symbol value to help find the real dependCheng Renquan
Sometimes when configuring need to disable some unused item, but the item is selected by many other items, it's hard to find the real dependency which selected it, This patch add every symbol's value accompanied to make it possible to find the real dependency easily. An example is CONFIG_RFKILL, ---------------------- RF switch subsystem support ---------------------- | CONFIG_RFKILL: | | | | Say Y here if you want to have control over RF switches | | found on many WiFi and Bluetooth cards. | | | | To compile this driver as a module, choose M here: the | | module will be called rfkill. | | | | Symbol: RFKILL [=m] | | Prompt: RF switch subsystem support | | Defined at net/rfkill/Kconfig:4 | | Depends on: NET [=y] | | Location: | | -> Networking support (NET [=y]) | | Selected by: IWLCORE [=n] && NETDEVICES [=y] && !S390 [=S390] && PC | | | ----------------------------------------------------------------( 99%)--- Signed-off-by: Cheng Renquan <crquan@gmail.com> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-01-28kconfig: tristate choices with mixed tristate and boolean valuesJan Beulich
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: explicitly introduce expression listRoman Zippel
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>
2008-01-28kconfig: rename E_OR & friends to avoid name clashSam Ravnborg
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>

2006-06-09kconfig: remove SYMBOL_{YES,MOD,NO}Roman Zippel

2005-01-05kconfig: Redo and improve search supportSam Ravnborg
Based on patch from: Roman Zippel <zippel@linux-m68k.org> The search functionality has been improved: - Restructured printout with more info - Include value of relevant symbols - Improved handling of corner cases - Generic search support moved to backend - ready to be utilised by xconfig and gconfig - Search functionality moved to fronend - not hardcoded in menubox.c Sample search (^$ used to limit search): Search for "^USB_STORAGE$": Symbol: USB_STORAGE [=y] Prompt: USB Mass Storage support Defined at drivers/usb/storage/Kconfig:7 Depends on: USB Location: -> Device Drivers -> USB Support Selects: SCSI Some symbols has loong "Depends on:" lines - for example FW_LOADER.

2004-03-18[PATCH] config: disable debug printsAndrew Morton
From: Roman Zippel <zippel@linux-m68k.org> This disables some debug prints, which are more confusing than helpful for normal users.
2003-06-02[PATCH] support for 'range'Roman Zippel
The 'range' keyword allows to define a lower and upper limit for integer and hex symbols.
2003-06-02[PATCH] reverse dependency supportRoman Zippel
The 'select' keyword defines a lower limit for symbols and allows to select other symbols when a symbol is selected, e.g.: config JOLIET bool "Microsoft Joliet CDROM extensions" select NLS This means when JOLIET is selected, NLS will be selected as well.
2003-06-02[PATCH] Remove old code and macrosRoman Zippel
Remove old code and debugging macros which were used by the cml1->kconfig converter.
2002-10-29[PATCH] new kernel configuration 2/7Roman Zippel
This adds the new kernel config core (library + the three front ends).
