Hi,
When "make KCONFIG_ALLCONFIG= mytmp.config alldefconfig", I find sym_calc_value() under scripts/kconfig/symbol.c is called many times. But I don't understand what does sym_calc_value() do. make KCONFIG_ALLCONFIG= mytmp.config alldefconfig -> scripts/kconfig/conf.c main() -> switch case alldefconfig -> conf_write() -> sym_calc_value() sym_calc_value() is also called in many other place. Can you tell me the function of sym_calc_value() ? main(): https://github.com/torvalds/linux/blob/9e8312f5e160ade069e131d54ab8652cf0e86e1a/scripts/kconfig/conf.c#L486 sym_calc_value(): https://github.com/torvalds/linux/blob/9e8312f5e160ade069e131d54ab8652cf0e86e1a/scripts/kconfig/symbol.c#L319 BestRegard, -- Csqshz
