Recall that kernel mode represents the privileged mode for code execution, while user mode represents the non-privileged mode ( for programs running outside the kernel). 回想一下内核模式表示代码执行的特权模式,而用户模式则表示非特权模式(用于那些运行在内核之外的程序)。
The Linux kernel is what's known as a monolithic kernel, which means that the majority of the operating system functionality is called the kernel and runs in a privileged mode. Linux就是通常所说的单内核(monolithickernel),即操作系统的大部分功能都被称为内核,并在特权模式下运行。
Another issue mentioned by the authors is that the device drivers run in privileged mode inside the OS, but they have become increasingly complicated. 作者提到的另一个问题是,设备驱动在操作系统中是运行在特权模式中的,但是它们变得越来越复杂。
Since driver code executes in the most privileged mode possible for the processor, there's almost no protection from wild stores. 对于处理器,既然驱动代码执行在最特别的模式中,哪里几乎没有来自野外存储的保护。
Switch configuration mode is entered from Privileged EXEC mode. 交换器组态模式是经由特权执行模式进入的。
