Hal is a set of libraries built on Linux drivers. This library is not part of the Linux kernel, but rather belongs to the application layer on top of the Linux kernel layer. One of the main purposes of HAL is to protect "private property" and the other is to try to avoid direct access to the Linux driver by the application.Linux drivers in traditional Linux systems typically have two types of code, access to hardware registers and business logic code.
