make menuconfig , with a menu-driven user interface, allows the user to choose the features of Linux (and other options) that will be compiled. … It is normally invoked using the command make menuconfig ; menuconfig is a target in Linux Makefile.
What is kernel configuration in Linux?
Kernel Options. There is a wide range of kernel configuration items that can be selected prior to the build phase. The build system is controlled by the contents of a . config file in the root directory of the kernel tree. The configuration file itself can be generated by issuing the make menuconfig command.
What does M mean in kernel config?
In Linux kernel config file, y,n and m stands for yes, no and module respectively. Most functionality in the Linux kernel can either be compiled in (y) or left out (n), and most of it can also be compiled as a loadable module(m). This makes sense when you don’t know exactly if you will need some feature in the future.

What is GKI Android?
The Generic Kernel Image (GKI) project addresses kernel fragmentation by unifying the core kernel and moving SoC and board support out of the core kernel into loadable modules. The GKI kernel presents a stable Kernel Module Interface (KMI) for kernel modules, so modules and kernel can be updated independently.
What is Android kernel?
What Is a Kernel? A kernel in an operating system—in this case Android—is the component responsible for helping your applications communicate with your hardware. It manages the system resources, communicates with external devices when needed, and so on. Android uses a variation of the Linux kernel.
