kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT

2014-04-07T23:36:09Z

"make allnoconfig" exists to ease testing of minimal configurations. Documentation/SubmitChecklist includes a note to test with allnoconfig. This helps catch missing dependencies on common-but-not-required functionality, which might otherwise go unnoticed. However, allnoconfig still leaves many symbols enabled, because they're hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't typically get build-tested with those disabled. To address this, introduce a new Kconfig option "allnoconfig_y", used on symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED (which then selects CONFIG_EXPERT). allnoconfig will then disable all the symbols hidden behind those. Signed-off-by: Josh Triplett Tested-by: Paul E.

localmodconfig: Add config depends by default settings

2013-12-20T22:02:44Z

Currently localmodconfig will miss dependencies from the default option. For example: config FOO default y if BAR || ZOO If FOO is needed for a module and is set to '=m', and so are BAR or ZOO, localmodconfig will not see that BOO or ZOO are also needed for the foo module, and will incorrectly disable them.

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.
