kconfig: remove unneeded menu_is_visible() call in conf_write_defconfig()

2024-03-18T17:30:51+00:00

When the condition 'sym == NULL' is met, the code will reach the 'next_menu' label regardless of the return value from menu_is_visible(). menu_is_visible() calculates some symbol values as a side-effect, for instance by calling expr_calc_value(menu->visibility), but all the symbol values will be calculated eventually.

kconfig: use generic macros to implement symbol hashtable

2024-02-20T11:47:45+00:00

Use helper macros in hashtable.h for generic hashtable implementation. We can git rid of the hash head index of for_all_symbols(). Signed-off-by: Masahiro Yamada

kconfig: call env_write_dep() right after yyparse()

2024-02-19T09:20:40+00:00

This allows preprocess.c to free up all of its resources when the parse stage is finished. It also ensures conf_write_autoconf_cmd() produces consistent results even if called multiple times for any reason. Signed-off-by: Masahiro Yamada

kconfig: write Kconfig files to autoconf.cmd in order

2024-02-19T09:20:40+00:00

Currently, include/config/autoconf.cmd saves included Kconfig files in reverse order. While this is not a big deal, it is inconsistent with other *.cmd files generated by fixdep. Output the included Kconfig files in the included order. Signed-off-by: Masahiro Yamada

kconfig: remove compat_getline()

2024-02-19T09:20:40+00:00

Commit 1a7a8c6fd8ca ("kconfig: allow long lines in config file") added a self-implemented getline() for better portability. However, getline() is standardized [1] and already used in other programs such as scripts/kallsyms.c. Use getline() provided by libc.

kconfig: WERROR unmet symbol dependency

2023-12-29T13:25:20+00:00

When KCONFIG_WERROR env variable is set treat unmet direct symbol dependency as a terminal condition (error). Suggested-by: Stefan Reinauer Signed-off-by: Sergey Senozhatsky Signed-off-by: Masahiro Yamada

kconfig: remove redundant NULL pointer check before free()

2023-12-28T07:22:47+00:00

Passing NULL to free() is allowed and is a no-op. Remove redundant NULL pointer checks. Signed-off-by: Masahiro Yamada

kconfig: massage the loop in conf_read_simple()

2023-11-28T02:22:51+00:00

Make the while-loop code a little more readable. The gain is that "CONFIG_FOO" without '=' is warned as unexpected data. Signed-off-by: Masahiro Yamada

kconfig: require an exact match for "is not set" to disable CONFIG option

2023-11-28T02:22:51+00:00

Currently, any string starting "is not set" disables a CONFIG option. For example, "# CONFIG_FOO is not settled down" is accepted as valid input, functioning the same as "# CONFIG_FOO is not set". It is a long-standing oddity. Check the line against the exact pattern "is not set". Signed-off-by: Masahiro Yamada

kconfig: introduce getline_stripped() helper

2023-11-28T02:22:51+00:00

Currently, newline characters are stripped away in multiple places on the caller. Doing that in the callee is helpful for further cleanups. Signed-off-by: Masahiro Yamada
