This occurs even if the content of the .config has not changed at all. This issue was mitigated by commit 67424f61f813 ("kconfig: do not write .config if the content is the same"); Kconfig does not update the .config when it ends up with the identical configuration. The issue is remaining when the .config is created by *_defconfig with some config fragment(s) applied on top. This is typical for powerpc and mips, where several *_defconfig targets are constructed by using merge_config.sh. One workaround is to have the copy of the .config. The filechk rule updates the copy, kernel/config_data, by checking the content instead of the timestamp. With this commit, the second run with the same configuration avoids the needless rebuilds. $ make ARCH=mips defconfig all [ snip ] $ make ARCH=mips defconfig all *** Default configuration is based on target '32r2el_defconfig' Using ./arch/mips/configs/generic_defconfig as base Merging arch/mips/configs/generic/32r2.config Merging arch/mips/configs/generic/el.config Merging ./arch/mips/configs/generic/board-boston.config Merging ./arch/mips/configs/generic/board-ni169445.config Merging ./arch/mips/configs/generic/board-ocelot.config Merging ./arch/mips/configs/generic/board-ranchu.config Merging ./arch/mips/configs/generic/board-sead-3.config Merging ./arch/mips/configs/generic/board-xilfpga.config # # configuration written to .config # SYNC include/config/auto.conf CALL scripts/checksyscalls.sh CALL scripts/atomic/check-atomics.sh CHK include/generated/compile.h CHK include/generated/autoksyms.h Reported-by: Elliot Berman Signed-off-by: Masahiro Yamada --- kernel/.gitignore | 1 + kernel/Makefile | 9 +++++++-- 2 files changed, 8 insertions(+), 2 deletions(-) (limited to 'kernel') diff --git a/kernel/.gitignore b/kernel/.gitignore index 4abc4e033ed8..dafdce3d18c5 100644 --- a/kernel/.gitignore +++ b/kernel/.gitignore @@ -1,2 +1,3 @@ # SPDX-License-Identifier: GPL-2.0-only +/config_data kheaders.md5 diff --git a/kernel/Makefile b/kernel/Makefile index e8a6715f38dc..4df609be42d0 100644 --- a/kernel/Makefile +++ b/kernel/Makefile @@ -142,10 +142,15 @@ obj-$(CONFIG_SCF_TORTURE_TEST) += scftorture.o $(obj)/configs.o: $(obj)/config_data.gz -targets += config_data.gz -$(obj)/config_data.gz: $(KCONFIG_CONFIG) FORCE +targets += config_data config_data.gz +$(obj)/config_data.gz: $(obj)/config_data FORCE $(call if_changed,gzip) +filechk_cat = cat $< + +$(obj)/config_data: $(KCONFIG_CONFIG) FORCE + $(call filechk,cat) + $(obj)/kheaders.o: $(obj)/kheaders_data.tar.xz quiet_cmd_genikh = CHK $(obj)/kheaders_data.tar.xz -- cgit v1.2.3-70-g09d2 From 9009b455811b0fa1f6b0adfa94db136984db5a38 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 30 Apr 2021 11:03:08 +0900 Subject: .gitignore: prefix local generated files with a slash The pattern prefixed with '/' matches files in the same directory, but not ones in sub-directories.
