2008-08-01 03:50:18     Assigning PFA and PFB channels to different pheripherals

Hi,

 

In My custom baord BF533, two pheripherals are interfaced with the PF Pins.

 

for assigning the interrupt i am using the request_irq function.

 

request_irq(IRQ_PF8(void *)IR_IRQ, SA_INTERRUPT, "IR_IRQ",NULL);

 

request_irq(IRQ_PF9(void *)SD_IRQ, SA_INTERRUPT, "SD_IRQ",NULL);

 

But i could see that both the interrupts are mapped to the same PFA channel, I want  one pheripheral to PFA and another to the PFB channel.

 

can anyone suggest me how i can do this.

 

Best Regards,Sreedhar

currently you cannot.  everything goes to interrupt "A".  i dont think there'd be any performance gain of separating the two today as you'd still have to go through demuxing the source to find out what is actually signaling.
