kconfig: Update config changed flag before calling callback

2023-03-13T18:46:09Z

Prior to commit 5ee546594025 ("kconfig: change sym_change_count to a boolean flag"), the conf_updated flag was set to the new value *before* calling the callback. xconfig's save action depends on this behaviour, because xconfig calls conf_get_changed() directly from the callback and now sees the old value, thus never enabling the save button or the shortcut. Restore the previous behaviour.

Kbuild: add Rust support

2022-09-28T07:02:20Z

Having most of the new files in place, we now enable Rust support in the build system, including `Kconfig` entries related to Rust, the Rust configuration printer and a few other bits.

kconfig: fix missing '# end of' for empty menu

2022-02-18T02:36:17Z

Currently, "# end of ..." is inserted when the menu goes back to its parent. Hence, an empty menu: menu "Foo" endmenu ... ends up with unbalanced menu comments, like this: # # Foo # Let's close the menu comments properly: # # Foo # # end of Foo Signed-off-by: Masahiro Yamada

kconfig: add fflush() before ferror() check

As David Laight pointed out, there is not much point in calling ferror() unless you call fflush() first. Reported-by: David Laight Signed-off-by: Masahiro Yamada

kconfig: fix failing to generate auto.conf

2022-02-12T14:24:19Z

When the KCONFIG_AUTOCONFIG is specified (e.g. export \ KCONFIG_AUTOCONFIG=output/config/auto.conf), the directory of include/config/ will not be created, so kconfig can't create deps files in it and auto.conf can't be generated. Signed-off-by: Jing Leng Signed-off-by: Masahiro Yamada

kbuild: do not quote string values in include/config/auto.conf

2022-01-08T09:03:57Z

The previous commit fixed up all shell scripts to not include include/config/auto.conf. Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf. These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAME I checked them one by one, and fixed up the code where necessary.

kconfig: refactor conf_touch_dep()

2021-10-11T14:13:23Z

If this function fails to touch a dummy header due to missing parent directory, then it creates it and touches the file again. This was needed because CONFIG_FOO_BAR was previously tracked by include/config/foo/bar.h. (include/config/foo/ may not exist here) This is no longer the case since commit 0e0345b77ac4 ("kbuild: redo fake deps at include/config/*.h"); now all the fake headers are placed right under include/config/, like include/config/FOO_BAR. Do not try to create parent directory, include/config/, which already exists. Signed-off-by: Masahiro Yamada

kconfig: refactor conf_write_dep()

2021-10-11T14:13:23Z

The if ... else inside the for-loop is unneeded because one empty line is placed after printing the last element of deps_config. Currently, all errors in conf_write_dep() are ignored. Add proper error checks. Rename it to conf_write_autoconf_cmd(), which is more intuitive. Signed-off-by: Masahiro Yamada
