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 even if the source tree is not configured at all because the inclusion of include/config/auto.conf was optional. So, I added one more patch in V2: https://patchwork.kernel.org/patch/10483637/ However, kbuild test robot reported a new warning message was displayed: Makefile:592: include/config/auto.conf: No such file or directory This warning is displayed only for Make 4.1 or older. To fix this annoying warning, I changed Kconfig too, which leaded to more clean-up, improvements in Kconfig. So, V3 became a big patch series. Only a few changes for V4. - I dropped the last patch in v3. - I am keeping include/config/auto.conf as the prerequisite of modules.builtin (11/11) Masahiro Yamada (11): kconfig: rename file_write_dep and move it to confdata.c kconfig: split out useful helpers in confdata.c kconfig: remove unneeded directory generation from local*config kconfig: create directories needed for syncconfig by itself kconfig: make syncconfig update .config regardless of sym_change_count kconfig: allow all config targets to write auto.conf if missing kbuild: use 'include' directive to load auto.conf from top Makefile kbuild: add .DELETE_ON_ERROR special target kbuild: do not update config when running install targets kbuild: do not update config for 'make kernelrelease' kbuild: remove auto.conf from prerequisite of phony targets Makefile | 44 +++++++++------ scripts/Kbuild.include | 3 + scripts/kconfig/Makefile | 16 ++---- scripts/kconfig/conf.c | 39 +++++++------ scripts/kconfig/confdata.c | 135 +++++++++++++++++++++++++++++++++++++------- scripts/kconfig/gconf.c | 1 + scripts/kconfig/lkc.h | 1 - scripts/kconfig/lkc_proto.h | 2 +- scripts/kconfig/mconf.c | 1 + scripts/kconfig/nconf.c | 1 + scripts/kconfig/qconf.cc | 2 + scripts/kconfig/util.c | 30 ---------- 12 files changed, 177 insertions(+), 98 deletions(-) -- 2.7.4
