目前正在调试SRIO doorbell中断程序，slave断已经能够正常接收到doorbell信息，并且相应的标志位也已经有了响应。但是slave端就是不进中断程序，接下来也不知道怎么去调试。
程序是触发INTDST0中断。接收到信号之后INTDST0_DECODE中的最后一位也被置为了1。大神指点一下该怎么去调试吧。不知道接下去怎么去做了。还有就是INTDST0_RATE_CNTL这个寄存器到底是什么意思啊。看半天文档都看不明白。
中断设置程序如下：
void initInt()
{
CSL_IntcContext intcContext;
CSL_IntcGlobalEnableState state;
CSL_IntcEventHandlerRecord EventRecord;
CSL_IntcParam vectId;
CSL_Status status;
CSL_IntcObj SrioIntcObj;
CSL_IntcHandle SrioIntcHandle;
CSL_IntcEventHandlerRecord record[11];
RIO_DOORBELL0_ICCR = 0xffffffff;
RIO_DOORBELL1_ICCR = 0xffffffff;
RIO_DOORBELL2_ICCR = 0xffffffff;
RIO_DOORBELL3_ICCR = 0xffffffff;
DSP_EVTCLR0 = 0xffffffff;
DSP_EVTCLR1 = 0xffffffff;
DSP_EVTCLR2 = 0xffffffff;
DSP_EVTCLR3 = 0xffffffff;
intcContext.eventhandlerRecord = record;
intcContext.numEvtEntries = 11;
status = CSL_intcInit(&intcContext);
if (status != CSL_SOK) {
printf("Intc initialization failed\n");
return;
}
/* Enable NMIs */
status = CSL_intcGlobalNmiEnable();
if (status != CSL_SOK) {
printf("Intc global NMI enable failed\n");
return;
}
/* Enable global interrupts */
status = CSL_intcGlobalEnable(&state);
if (status != CSL_SOK) {
printf ("Intc global enable failed\n");
return;
}
/* Opening intc module */
vectId = CSL_INTC_VECTID_8;
SrioIntcHandle = CSL_intcOpen (&SrioIntcObj, CSL_INTC_EVENTID_RIOINT0, \
&vectId , NULL);
if (SrioIntcHandle == NULL) {
printf("Intc open failed\n");
return;
}
EventRecord.handler = (CSL_IntcEventHandler)&eventSrioHandler;
EventRecord.arg = (void*)(SrioIntcHandle);
status = CSL_intcPlugEventHandler(SrioIntcHandle,&EventRecord);
if (status != CSL_SOK) {
printf("Intc plug event handler failed\n");
return;
}
CSL_intcHwControl(SrioIntcHandle, CSL_INTC_CMD_EVTCLEAR, NULL);
CSL_intcHwControl(SrioIntcHandle, CSL_INTC_CMD_EVTENABLE, NULL);
}
