Some questions about the operating system-General Linux technology-Linux technology and application information. The following is a detailed description. Linux and Windows can both run on my laptop. how does Liunx and Windows access my laptop hardware resources? In Linux, what API functions are called to operate my laptop hardware? in windows, what API functions are called to operate my laptop hardware resources?

Why can Linux run on both ARM and notebook? Does ARM Development Board and notebook provide the same hardware interface for Linux?

I personally think: Linux and windows and hardware board interfaces are standardized. you only need to fill in the hardware interface function to provide hardware operation methods for Linux and Windows. Because both Linux and Windows use standard hardware interface functions to operate hardware resources, the operating system itself does not care about the hardware interface function body, but only the name of the hardware interface function. Hardware interface functions need to be prepared by the transplant according to the situation of the circuit board.
