kernel会往input设备中注册一些handler。一个设备可以有多个串行的handler goldfish_events将设置一个输入事件中断函数events_interrupt,当有事件来时候,该函数会将信息投递给input框架处理(调用input_event函数) input_event函数将调用各个handler处理之。对于goldfish来说,最重要的handler就是evdev,它把信息整理并上报给Event...

The BSP interrupt handler in the BSP_PCA100XX example is called bsp_evt_handler(). This event handler is set when calling bsp_init() inside main. This interrupt handler is called when a set of events are flagged, these events are described in the SDK....
