The Linux kernel is highly customizable and can be customized by configuring the compilation options.When configuring the kernel compilation option, there are generally three compiler options for the driver, not compiling, compiling kernel-driven, and compiling to module-driven. So Linux drivers are generally divided into two categories, kernel-driven and module-driven, of course, there is no absolute difference between the two; when compiled into ker
