kconfig: do not use OR-assignment for zero-cleared structure

2020-05-12T04:28:30+00:00

The simple assignment is enough because memset() three lines above has zero-cleared the structure. Signed-off-by: Masahiro Yamada

kconfig: make 'imply' obey the direct dependency

2020-03-13T01:05:34+00:00

The 'imply' statement may create unmet direct dependency when the implied symbol depends on m. [Test Code] config FOO tristate "foo" imply BAZ config BAZ tristate "baz" depends on BAR config BAR def_tristate m config MODULES def_bool y option modules If you set FOO=y, BAZ is also promoted to y, which results in the following .config file: CONFIG_FOO=y CONFIG_BAZ=y CONFIG_BAR=m CONFIG_MODULES=y This does not meet the dependency 'BAZ depends on BAR'. Unlike 'select', what is worse, Kconfig never shows the 'WARNING: unmet direct dependencies detected for ...' for this case. Because 'imply' is considered to be weaker than 'depends on', Kconfig should take the direct dependency into account. For clarification, describe this case in kconfig-language.rst too.

kconfig: allow symbols implied by y to become m

2020-03-13T01:05:34+00:00

The 'imply' keyword restricts a symbol to y or n, excluding m when it is implied by y. This is the original behavior since commit 237e3ad0f195 ("Kconfig: Introduce the "imply" keyword"). However, the author of this feature, Nicolas Pitre, stated that the 'imply' keyword should not impose any restrictions. (https://lkml.org/lkml/2020/2/19/714) I agree, and want to get rid of this tricky behavior. Suggested-by: Nicolas Pitre Signed-off-by: Masahiro Yamada Acked-by: Nicolas Pitre

kconfig: squash prop_alloc() into menu_add_prop()

prop_alloc() is only called from menu_add_prop(). Squash it. Signed-off-by: Masahiro Yamada

kconfig: remove sym from struct property

2020-01-06T17:18:44+00:00

struct property can reference to the symbol that it is associated with by prop->menu->sym. Fix up the one usage of prop->sym, and remove sym from struct property. Signed-off-by: Masahiro Yamada

docs: kbuild: convert docs to ReST and rename to *.rst

2019-06-14T20:21:21+00:00

The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Corbet

kconfig: split some C files out of zconf.y

2018-12-28T13:22:38+00:00

I want to compile each C file independently instead of including all of them from zconf.y. Split out confdata.c, expr.c, symbol.c, and preprocess.c . These are low-hanging fruits. Signed-off-by: Masahiro Yamada

kconfig: convert to SPDX License Identifier

2018-12-28T13:22:28+00:00

All files in lxdialog/ are licensed under GPL-2.0+, and the rest are under GPL-2.0. I added GPL-2.0 tags to test scripts in tests/. Documentation/process/license-rules.rst does not suggest anything about the flex/bison files. Because flex does not accept the C++ comment style at the very top of a file, I used the C style for zconf.l, and so for zconf.y for consistency. Signed-off-by: Masahiro Yamada
