A new ioctl command should be added to the device driver to control the interrupt simulation from the test application.
ioctl命令应该添加到设备驱动程序中，这样就可以从测试应用程序中控制对中断的模拟了。
A separate ioctl command should be introduced to have control over interrupt simulation (see the section on the ioctl interface).

On top of these register #define macros, you should also define another macro that dictates whether the ISR will run in simulation mode or in the original interrupt context. For example
在这些寄存器的 #define宏前面，还应该定义另外一个宏，它用来说明 ISR 是在模拟模式中运行还是在原来的中断上下文中运行的。
