kconfig: Use KCONFIG_CONFIG instead of .config

2023-12-28T07:22:47Z

When using a custom location for kernel config files this merge config command fails as it doesn't use the configuration set with KCONFIG_CONFIG. Signed-off-by: Markus Schneider-Pargmann Signed-off-by: Masahiro Yamada

kconfig: factor out common code shared by mconf and nconf

kbuild: support W=c and W=e shorthands for Kconfig

2023-12-03T09:50:48Z

KCONFIG_WARN_UNKNOWN_SYMBOLS=1 and KCONFIG_WERROR=1 are descriptive and suitable in scripting, but typing them from the command line can be tedious. Associate them with KBUILD_EXTRA_WARN (and the W= shorthand). Support a new letter 'c' to enable extra checks in Kconfig. You can still manage compiler warnings (W=1) and Kconfig warnings (W=c) independently. Reuse the letter 'e' to turn Kconfig warnings into errors. As usual, you can combine multiple letters in KCONFIG_EXTRA_WARN. $ KCONFIG_WARN_UNKNOWN_SYMBOLS=1 KCONFIG_WERROR=1 make defconfig can be shortened to: $ KBUILD_EXTRA_WARN=ce make defconfig or, even shorter: $ make W=ce defconfig Signed-off-by: Masahiro Yamada Reviewed-by: Nathan Chancellor

kbuild: Show marked Kconfig fragments in "help"

2023-09-03T17:04:20Z

Currently the Kconfig fragments in kernel/configs and arch/*/configs that aren't used internally aren't discoverable through "make help", which consists of hard-coded lists of config fragments. Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment. Add comments to fragments that are intended to be direct targets.

kconfig: Update all declared targets

2023-01-13T07:29:52Z

Currently qconf-cfg.sh is the only script that touches the "-bin" target, even though all of the conf_cfg rules declare that they do. Make the recipe unconditionally touch all declared targets to avoid incompatibilities with upcoming versions of GNU make: https://lists.gnu.org/archive/html/info-gnu/2022-10/msg00008.html e.g. scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/nconf-bin'. scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/mconf-bin'. scripts/kconfig/Makefile:215: warning: pattern recipe did not update peer target 'scripts/kconfig/gconf-bin'.

kconfig: refactor Makefile to reduce process forks

Refactor Makefile and use read-file macro. For Make >= 4.2, it can read out a file by using the built-in function. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

kconfig: Add `make mod2noconfig` to disable module options

2021-12-02T08:02:36Z

When converting a modular kernel to a monolithic kernel, once the kernel works without loading any modules, this helps to quickly disable all the modules before turning off module support entirely. Refactor conf_rewrite_mod_or_yes to a more general conf_rewrite_tristates that accepts an old and new state. Signed-off-by: Josh Triplett Tested-by: Björn Töpel Signed-off-by: Masahiro Yamada

kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native build

2021-04-14T06:22:49Z

When the .config file is missing, 'make config', 'make menuconfig', etc. uses a file listed in DEFCONFIG_LIST, if found, as base configuration. Ususally, /boot/config-$(uname -r) exists, and is used as default. However, when you are cross-compiling the kernel, it does not make sense to use /boot/config-* on the build host. It should default to arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). UML previously did not use DEFCONFIG_LIST at all, but it should be able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file. Signed-off-by: Masahiro Yamada

kconfig: do not use allnoconfig_y option

2021-04-14T06:22:49Z

allnoconfig_y is an ugly hack that sets a symbol to 'y' by allnoconfig. allnoconfig does not mean a minimal set of CONFIG options because a bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do not like to hack Kconfig this way. Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one liner config fragment. CONFIG_EMBEDDED=y is still forced when allnoconfig is invoked as a part of tinyconfig. No change in the .config file produced by 'make tinyconfig'. The output of 'make allnoconfig' will be changed; we will get CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.
