![]() 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 lines 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 makes more sense 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 [2] arch/$(ARCH)/defconfig This file path is no longer valid.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. I moved the default KBUILD_DEFCONFIG to the top Makefile. Otherwise, the 7 architectures listed above would end up with endless loop of syncconfig.
