try to read a kconfig file. OK, now that we have an understanding of these keywords, let's take a look at the formation of this menu list. After running make menuconfig, the system's configuration tool first analyzes the/arch/arch/kconfig corresponding to the architectureThe file (the Arch argument that appears here is at the end of this article). It actually refers to the second, another important role------introduction of Kbuild Makefile The Kconfig file helps the user complete the confi
