kconfig: remove trailing whitespaces

2019-05-09T13:37:17+00:00

There are still some trailing whitespaces under scripts/kconfig/tests/, but they must be kept. Otherwise, "make testconfig" would break. Signed-off-by: Masahiro Yamada

kconfig: surround dbg_sym_flags with #ifdef DEBUG to fix gconf warning

2018-12-28T13:22:39+00:00

Fix the following warning: no previous prototype for ‘dbg_sym_flags’ [-Wmissing-prototypes] Signed-off-by: Masahiro Yamada

kconfig: split images.c out of qconf.cc/gconf.c to fix gconf warnings

2018-12-28T13:22:39+00:00

Currently, images.c is included by qconf.cc and gconf.c. qconf.cc uses all of xpm_* arrays, but gconf.c only some of them. Hence, lots of "... defined but not used" warnings are displayed while compiling gconf.c Splitting out images.c fixes the warnings. Signed-off-by: Masahiro Yamada

kconfig: add static qualifiers to fix gconf warnings

2018-12-28T13:22:39+00:00

Add "static" to functions that are locally used in gconf.c This fixes some "no previous prototype for ..." warnings. 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

kconfig: allow all config targets to write auto.conf if missing

2018-07-25T14:25:30+00:00

Currently, only syncconfig creates or updates include/config/auto.conf and some other files. Other config targets create or update only the .config file. When you configure and build the kernel from a pristine source tree, any config target is followed by syncconfig in the build stage since include/config/auto.conf is missing. We are moving compiler tests from Makefile to Kconfig. It means that parsing Kconfig files will be more costly since Kconfig invokes the compiler commands internally. Thus, we want to avoid invoking Kconfig twice (one for *config to create the .config, and one for syncconfig to synchronize the auto.conf). If auto.conf does not exist, we can generate all configuration files in the first configuration stage, which will save the syncconfig in the build stage. Please note this should be done only when auto.conf is missing. If *config blindly did this, time stamp files under include/config/ would be unnecessarily touched, triggering unneeded rebuild of objects. I assume a scenario like this: 1. You have a source tree that has already been built with CONFIG_FOO disabled 2. Run "make menuconfig" to enable CONFIG_FOO 3. CONFIG_FOO turns out to be unnecessary. Run "make menuconfig" again to disable CONFIG_FOO 4. Run "make" In this case, include/config/foo.h should not be touched since there is no change in CONFIG_FOO. The sync process should be delayed until the user really attempts to build the kernel. This commit has another motivation; I want to suppress the 'No such file or directory' warning from the 'include' directive. The top-level Makefile includes auto.conf with '-include' directive, like this: ifeq ($(dot-config),1) -include include/config/auto.conf endif This looks strange because auto.conf is mandatory when dot-config is 1. I guess only the reason of using '-include' is to suppress the warning 'include/config/auto.conf: No such file or directory' when building from a clean tree. However, this has a side-effect; Make considers the files included by '-include' are optional. Hence, Make continues to build even if it fails to generate include/config/auto.conf. I will change this in the next commit, but the warning message is annoying. (At least, kbuild test robot reports it as a regression.) With this commit, Kconfig will generate all configuration files together with the .config and I guess it is a solution good enough to suppress the warning. Note: GNU Make 4.2 or later does not display the warning from the 'include' directive if include files are successfully generated. See GNU Make commit 87a5f98d248f ("[SV 102] Don't show unnecessary include file errors.") However, older GNU Make versions are still widely used. Signed-off-by: Masahiro Yamada

kconfig: rename SYMBOL_AUTO to SYMBOL_NO_WRITE

2018-07-17T16:18:09+00:00

Over time, the use of the flag SYMBOL_AUTO changed from initially marking three automatically generated symbols ARCH, KERNELRELEASE and UNAME_RELEASE to today's effect of protecting symbols from being written out. Currently, only symbols of type CHOICE and those with option defconf_list set have that flag set. Reflect that change in semantics in the flag's name.

kconfig: drop localization support

2018-05-28T09:25:21+00:00

The localization support is broken and appears unused. There is no google hits on the update-po-config target. And there is no recent (5 years) activity related to the localization. So lets just drop this as it is no longer used. Suggested-by: Ulf Magnusson Suggested-by: Masahiro Yamada Signed-off-by: Sam Ravnborg Signed-off-by: Masahiro Yamada

gconfig: remove misleading parentheses around a condition

2017-03-21T17:56:33+00:00

When building the kernel with clang, the compiler complains about the presence of a condition inside two pairs of parentheses: scripts/kconfig/gconf.c:917:19: error: equality comparison with extraneous parentheses [-Werror,-Wparentheses-equality] } else if ((col == COL_OPTION)) { ~~~~^~~~~~~~~~~~~ scripts/kconfig/gconf.c:917:19: note: remove extraneous parentheses around the comparison to silence this warning } else if ((col == COL_OPTION)) { ~ ^ ~ scripts/kconfig/gconf.c:917:19: note: use '=' to turn this equality comparison into an assignment } else if ((col == COL_OPTION)) { ^~ = Silence this warning by removing a level of parentheses.

kconfig: Do not print status messages in make -s mode

2015-04-09T15:44:34+00:00

Add an -s option to the various frontends and pass it when make -s is used. Also, use $(kecho) instead of @echo in the Makefile. Signed-off-by: Michal Marek
