71 * @brief
72@verbatim
73什么情况下会发生从用户态向内核态切换。这里细分为3种情况:
74
751、发生系统调用时
76
77这是处于用户态的进程主动请求切换到内核态的一种方式。用户态的进程通过系统调用
78申请使用操作系统提供的系统调用服务例程来处理任务。而系统调用的机制，其核心仍
79是使用了操作系统为用户特别开发的一个中断机制来实现的，即软中断。
80
812、产生异常时
82
83当CPU执行运行在用户态下的程序时，发生了某些事先不可知的异常，这时会触发由当前
84运行的进程切换到处理此异常的内核相关的程序中，也就是转到了内核态，如缺页异常。
85
863、外设产生中断时
87
88当外围设备完成用户请求的操作后，会向CPU发出相应的中断信号，这时CPU会暂停执行下
89一条即将要执行的指令转而去执行与中断信号对应的处理程序，如果先前执行的指令是
90用户态下的程序，那么这个转换的过程自然也就发生了由用户态到内核态的切换。
91比如硬盘读写操作的完成，系统会切换到硬盘读写的中断处理程序中执行后续操作等。
92可以看到上述三种由用户态切换到内核态的情况中，只有系统调用是进程主动请求发生切换的，
93中断和异常都是被动的。
