kconfig: Add yes2modconfig and mod2yesconfig targets.

2020-01-06T17:18:45+00:00

Since kernel configs provided by syzbot are close to "make allyesconfig", it takes long time to rebuild. This is especially waste of time when we need to rebuild for many times (e.g. doing manual printk() inspection, bisect operations). We can save time if we can exclude modules which are irrelevant to each problem. But "make localmodconfig" cannot exclude modules which are built into vmlinux because /sbin/lsmod output is used as the source of modules. Therefore, this patch adds "make yes2modconfig" which converts from =y to =m if possible. After confirming that the interested problem is still reproducible, we can try "make localmodconfig" (and/or manually tune based on "Modules linked in:" line) in order to exclude modules which are irrelevant to the interested problem. While we are at it, this patch also adds "make mod2yesconfig" which converts from =m to =y in case someone wants to convert from =m to =y after "make localmodconfig".

kconfig: squash prop_alloc() into menu_add_prop()

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

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

kconfig: require the argument of --defconfig

2019-06-09T06:08:18+00:00

Currently, the argument for --defconfig is optional. If the argument is not passed, the hard-coded default arch/$(ARCH)/defconfig is used. It no longer happens in Linux since the last users of the default are gone by the following commits: - Commit f3e20ad67b4c ("s390: move arch/s390/defconfig to arch/s390/configs/defconfig") - Commit 986a13769c4b ("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig") I want to kill the Linux-specific directory path embedded in the Kconfig binary. The --savedefconfig (reverse operation of --defconfig) requires an argument, so it should not hurt to do likewise for --defconfig. Signed-off-by: Masahiro Yamada

kconfig: make conf_get_autoconfig_name() static

2019-05-14T14:23:25+00:00

This is only used in confdata.c Signed-off-by: Masahiro Yamada

kconfig: rename zconf.l to lexer.l

2019-02-13T14:25:49+00:00

Use a more logical name. Signed-off-by: Masahiro Yamada

kconfig: split the lexer out of zconf.y

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

Compile zconf.lex.c independently of the other files. Signed-off-by: Masahiro Yamada

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

kconfig: remove keyword lookup table entirely

2018-12-28T11:44:38+00:00

Commit 7a88488bbc23 ("[PATCH] kconfig: use gperf for kconfig keywords") introduced gperf for the keyword lookup. Then, commit bb3290d91695 ("Remove gperf usage from toolchain") killed the gperf use. As a result, the linear keyword search was left behind. If we do not use gperf, there is no reason to have the separate table of the keywords. Move all keywords back to the lexer. I also refactored the lexer to remove the COMMAND and PARAM states. Signed-off-by: Masahiro Yamada

kconfig: refactor scanning and parsing "option" properties

2018-12-21T15:25:52+00:00

For the keywords "modules", "defconfig_list", and "allnoconfig_y", the lexer should pass specific tokens instead of generic T_WORD. This simplifies both the lexer and the parser. Signed-off-by: Masahiro Yamada
