XDMA 中断的问题

如图，我将3个信号作为中断信号同时给了PS和XDMA，我在PS中用SDK检测3个中断信号

GicConfig = XScuGic_LookupConfig(XPAR_PS7_SCUGIC_0_DEVICE_ID);
    XScuGic_CfgInitialize(&InterruptController, GicConfig,GicConfig->CpuBaseAddress);
    Xil_ExceptionRegisterHandler(XIL_EXCEPTION_ID_INT,
                (Xil_ExceptionHandler) XScuGic_InterruptHandler,
                &InterruptController);
    Xil_ExceptionEnable();
    XScuGic_Connect(&InterruptController, PULSE_EVENT,
                   (Xil_ExceptionHandler)PULSE_EVENT_Handler,
                   (void *)&InterruptController);
    XScuGic_Connect(&InterruptController, IRQ_EVENT,
                   (Xil_ExceptionHandler)IRQ_EVENT_Handler,
                   (void *)&InterruptController);
    XScuGic_Connect(&InterruptController, OVERFLOW_EVENT,
                   (Xil_ExceptionHandler)OVERFLOW_EVENT_Handler,
                   (void *)&InterruptController);
    XScuGic_SetPriorityTriggerType(&InterruptController, PULSE_EVENT,40,0b11);
    XScuGic_SetPriorityTriggerType(&InterruptController, IRQ_EVENT,40,0b11);
    XScuGic_SetPriorityTriggerType(&InterruptController, OVERFLOW_EVENT,40,0b11);
    XScuGic_Enable(&InterruptController, PULSE_EVENT);
    XScuGic_Enable(&InterruptController, IRQ_EVENT);
    XScuGic_Enable(&InterruptController, OVERFLOW_EVENT);


显示中断信号识别正常，采用的是上升沿触发模式
但是我在Linux QT中， 根据汤老板的代码

event1_fd = open("/dev/xdma0_events_1",O_RDWR | O_SYNC);
    if(event1_fd < 0)
        return -3;
event0_fd = open("/dev/xdma0_events_0",O_RDWR | O_SYNC);
    if(event0_fd < 0)
        return -4;
event2_fd = open("/dev/xdma0_events_2",O_RDWR | O_SYNC);
    if(event2_fd < 0)
        return -5;

int read_event(int fd)
{
    int val;
    read(fd,&val,4);
    return val;
}

void pulseeventthread::run()
{
    while(1)
    {
        read_event(event0_fd);
        emit sig_pulse_event_emit();
    }
}


connect(&pulse_event_thread,SIGNAL(sig_pulse_event_emit()),this,SLOT(pulse_event_occurs()));

void MainWindow::pulse_event_occurs()
{
    ui->lb_pulse_event->setText("get event");
}

发现read_event得不到这3个中断信号，请问下汤老板有遇到这样的情况吗，
驱动测试读写h2c c2h和 user 都可以正常工作了
