* [PATCH] kbuild: use KBUILD_DEFCONFIG as the fallback for DEFCONFIG_LIST @ 2020-02-16 15:45 ` Masahiro Yamada 2020-02-21 8:50 ` Marek Szyprowski 0 siblings, 1 reply; 4+ messages in thread From: Masahiro Yamada @ 2020-02-16 15:45 UTC (permalink / raw) To: linux-kbuild Cc: x86, sparclinux, linux-sh, linux-um, linux-kernel, Masahiro Yamada, Albert Ou, Anton Ivanov, Borislav Petkov, David S. Miller, Greentime Hu, Guo Ren, H. Peter Anvin, Ingo Molnar, Jeff Dike, Nick Hu, Palmer Dabbelt, Paul Walmsley, Rich Felker, Richard Weinberger, Thomas Gleixner, Vincent Chen, Yoshinori Sato, linux-riscv Most of the Kconfig commands (except defconfig and all*config) read the .config file as a base set of CONFIG options. When it does not exist, the files in DEFCONFIG_LIST are searched in this order and loaded if found. I do not see much sense in the last two entries in DEFCONFIG_LIST. [1] ARCH_DEFCONFIG The entry for DEFCONFIG_LIST is guarded by 'depends on !UML'. So, the ARCH_DEFCONFIG definition in arch/x86/um/Kconfig is meaningless. arch/{sh,sparc,x86}/Kconfig define ARCH_DEFCONFIG depending on 32 or 64 bit variant symbols. This is a little bit strange; ARCH_DEFCONFIG should be a fixed string because the base config file is loaded before the symbol evaluation stage. Using KBUILD_DEFCONFIG is saner because it is fixed before Kconfig is invoked. Fortunately, arch/{sh,sparc,x86}/Makefile define it in the same way, and it works as expected. Hence, replace ARCH_DEFCONFIG with "arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG)". [2] arch/$(ARCH)/defconfig This file path is no longer valid. The defconfig files are always located in the arch configs/ directories. $ find arch -name defconfig | sort arch/alpha/configs/defconfig arch/arm64/configs/defconfig arch/csky/configs/defconfig arch/nds32/configs/defconfig arch/riscv/configs/defconfig arch/s390/configs/defconfig arch/unicore32/configs/defconfig The path arch/*/configs/defconfig is already covered by "arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG)". So, this file path is not necessary.
