我的理解是两者是包含关系,kernel (内核)是核心,是控制管理系统资源的,而OS 是接口,是kernel的延伸

When the hardware wants to interface with the application and broader system, an interrupt is issued across the processor and kernel to manage resources efficiently. The kernel, existing inside a hard OS shell, controls all primary functions of the respective hardware, independent of the device, ...

linux 内核启动过程中,start_kernel()函数是分析Linux内核的切入点。 C语言阶段的start_kernel函数位于内核源码/init/main.c文件,主要完成以下内容: (1)打印一些输出信息。 (2)初始化内核工作所需的模块(比如内存管理、调度系统、异常处理等)。 start_kernel函数 ...
