[PATCH v4 04/11] kconfig: create directories needed for syncconfig by itself

'make syncconfig' creates some files such as include/config/auto.conf, include/generate/autoconf.h, etc. but the necessary directory creation relies on scripts/kconfig/Makefile. To make Kconfig self-contained, create directories as needed in conf_write_autoconf(). This change allows

[PATCH v4 01/11] kconfig: rename file_write_dep and move it to confdata.c

file_write_dep() is called only from conf_write_autoconf(). Move it from util.c to confdata.c to make it static. Also, rename it to conf_write_dep() since it should belong to the group of conf_write* functions. Signed-off-by: Masahiro Yamada --- Changes in v4: None scripts/kconfig/confdata.c

[PATCH v4 05/11] kconfig: make syncconfig update .config regardless of sym_change_count

syncconfig updates the .config only when sym_change_count > 0, i.e. any change in config symbols has been detected. Not only symbols but also comments are contained in the .config file. If only comments are updated, they are not fed back to the .config, then the stale comments are left-over. Of

[PATCH v4 09/11] kbuild: do not update config when running install targets

"make syncconfig" is automatically invoked when any of the following happens: - .config is updated - any of Kconfig files is updated - any of environment variables referenced in Kconfig is changed Then, it updates configuration files such as include/config/auto.conf

[PATCH v4 00/11] kbuild/kconfig: do not update config during installation

The main motivation of this patch series is to suppress the syncconfig during running installation targets. V1 consisted of only two patches: https://patchwork.kernel.org/patch/10468105/ https://patchwork.kernel.org/patch/10468103/ I noticed that installation targets would continue running

[PATCH v2] checkpatch: kbuild: if_changed: check for multiple calls in targets

The kbuild function if_changed should not be called more than once for a target. Because that function writes the command line to a .cmd file for later tests, multiple calls of it within a target would result in overwrites of previous values and effectively render the command line test

[PATCH v4 11/11] kbuild: remove auto.conf from prerequisite of phony targets

[PATCH v4 10/11] kbuild: do not update config for 'make kernelrelease'

'make kernelrelease' depends on CONFIG_LOCALVERSION(_AUTO), but for the same reason as install targets, we do not want to update the configuration just for printing the kernelrelease string. This is likely to happen when you compiled the kernel with CROSS_COMPILE, but forget to pass it to 'make

[PATCH v4 06/11] kconfig: allow all config targets to write auto.conf if missing

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

[PATCH v4 08/11] kbuild: add .DELETE_ON_ERROR special target

If Make gets a fatal signal while a shell is executing, it may delete the target file that the recipe was supposed to update. This is needed to make sure that it is remade from scratch when Make is next run; if Make is interrupted after the recipe has begun to write the target file, it results in
