A question about AMBA_NR_IRQS

unifoxz · 12-29-2011, 07:22 AM

From include/linux/amba/bus.h,

Code:

 20 #define AMBA_NR_IRQS    2
 21 
 22 struct amba_device {
 23         struct device           dev;
 24         struct resource         res;
 25         u64                     dma_mask;
 26         unsigned int            periphid;
 27         unsigned int            irq[AMBA_NR_IRQS];
 28 };

Does anyone know what is AMBA_NR_IRQS and why it is set as 2?

Thank you.

I am sorry I have post to the wrong section, I suppose to post this to Linux - Kernel.
What can I do to delete this post or move it to its right position?

Thank you.
