Hi, I'm in the process of porting Linux to one of our boards based on an 8641D. Some of the interrupts of on-board devices are dealt with by a custom interrupt controller in one of the onboard FPGAs, which cascades into the 8641D's mpic. I'm trying to write a driver for it.
Looking at examples of cascaded interrupt handlers I've managed to get to the point where the kernel is trying to register interrupts from the DTB file I provide it. The problem is I don't know what virqs are being assigned to the interrupts or how virqs are/should be assigned to a cascaded interrupt controller. Can anyone point me towards any documentation that my naïve googling is missing or explain how this should work?
