xconfig: Fix the filename for GUI settings

2013-10-08T21:52:16Z

Currently the qconf program invoked by 'make xconfig' stores GUI settings in the file ~/.config/Unknown\ Organization.conf. This name is apparently generated by the QSettings class when no organisation or application name are specified. This is obviously not a sensible filename (nor does it seem sensible that these QSettings parameters are optional!). Pass the names 'kernel.org' and 'qconf', resuling in the filename ~/.config/kernel.org/qconf.conf. Signed-off-by: Ben Hutchings Reviewed-by: "Yann E. MORIN" Tested-by: "Yann E.

kconfig: fix bug in search results string: use strlen(gstr->s), not gstr->len

2013-10-08T21:52:16Z

The struct gstr has a capacity that may differ from the actual string length. However, a string manipulation in the function search_conf made the assumption that it is the same, which led to messing up some search results, especially when the content of the gstr in use had not yet reached at least 63 chars.

kconfig: remove unused definition from scanner

2013-10-08T21:52:15Z

The definition ws [ \n\t] is not used anywhere. Drop it to avoid confusion. As it is a dead definition, any changes in the resulting code generated by flex would be surprising (actually testing this showed that there are really no changes). So, there is no need to touch the existing zconf.lex.c_shipped. Signed-off-by: Martin Walch Reviewed-by: "Yann E. MORIN" Signed-off-by: "Yann E. MORIN:

kconfig: adjust warning message for conflicting types

2013-10-08T21:52:15Z

Each symbol must have exactly one type assigned. However, if a symbol happens to have two different types assigned at runtime, a warning is printed and the first type is preserved while the second type is being ignored. The warning message says type of redefined from to which may be misleading as it may create the impression that the second type replaces the first type.

kconfig: fix trivial typos and update mconf documentation

2013-10-08T21:52:14Z

This fixes lots of typos in comments and strings. It also updates the documentation strings in mconf to reflect the changes in the user interface from the two commits 6364fd0cb1e4c7f72b974613e0cf5744ae4d2cb2 menuconfig: Add Save/Load buttons 1bdbac478a858d2aa73a6784c7c2e09de0f6d06b menuconfig: Get rid of the top-level entries for "Load an Alternate/Save an Alternate" And it updates the layout of the example search result, i. e. moves down the "Defined at" and "Depends on" lines and adds a symbol state ([=n]) to the symbol in the "Selected by" line. Furthermore, the help texts now should fit in 80 columns again when viewed in mconf. Signed-off-by: Martin Walch Reviewed-by: Jean Delvare Reviewed-by: Wang YanQing Signed-off-by: "Yann E. MORIN"

kconfig: do not allow more than one symbol to have 'option modules'

2013-09-05T09:10:08Z

Previously, it was possible to have more than one symbol with the 'option modules' attached to them, although only the last one would in fact control tristates. Since this does not make much sense, only allow at most one symbol to control tristates. Note: it is still possible to have more than one symbol that control tristates, but indirectly: config MOD1 bool "mod1" select MODULES config MOD2 bool "mod2" select MODULES config MODULES bool option modules Signed-off-by: "Yann E.

kconfig: do not special-case 'MODULES' symbol

2013-09-05T09:09:17Z

Currently, the 'MODULES' symbol is hard-coded to be the default symbol that enables/disables tristates, if no other symbol was declared with 'option modules'. While this used to be needed for the Linux kernel, we now have an explicit 'option modules' attached to the 'MODULES' symbol (since cset 11097a036), so we no longer need to special-case it in the kconfig code. Furthermore, kconfig is extensively used out of the Linux kernel, and other projects may have another meaning for a symbol named 'MODULES'. This patch changes the way we enable/disable tristates: if a symbol was found with 'option modules' attached to it, then that symbol controls enabling tristates. Otherwise, tristates are disabled, even if a symbol named 'MODULES' exists. Signed-off-by: "Yann E. MORIN" Cc: Sam Ravnborg Signed-off-by: Michal Marek

kconfig: silence warning when parsing auto.conf when a symbol has changed type

2013-08-15T20:48:08Z

When a symbol changes type from tristate to bool, and was previously set to 'm', a subsequent silentoldconfig would warn about inconsistency, such as: include/config/auto.conf:3014:warning: symbol value 'm' invalid for HOTPLUG_PCI_PCIE Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal): git checkout 1fe0135 make mrproper make allmodconfig make silentoldconfig git checkout aa8032b make allmodconfig make silentoldconfig Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig, but then was set to 'y' by the second allmodconfig. Then the second silentoldconfig prints the warning. The warning in this case is a spurious warning, which happens at the time kconfig tries to detect symbols that have changed, to touch the empty header files in include/config used for dependency-tracking by make. Silence the warning when we read the old auto.conf file, since it is perfectly legit that a symbol changed type since the previous call.
