The only real change is that we now request an interrupt for the camera deviceinterrupt line.
唯一的实质性变化就是我们为摄像头设备中断行请求一个中断。

This article helps device driver developers test the interrupt service routine as much as possible by simulating the various interrupts.
本文通过模拟各种中断,尽可能地帮助设备驱动程序开发人员测试中断服务例程。

And finally, the driver is tightly coupled with various APIs and applications, and you may have to debug a device driver where interrupt losses and out-of-sequence interrupts happen.
