[ECOS] Interrupt vectors

[David Brennan]

I am currently trying to implement a device driver for the Tundra 
Universe chip. I have everything working, except I want to be able to 
have the user program install interrupts off the chip. The main hardware 
interrupt function would be the same for all. But the chip can generate 
7 interrupts, each with 256 vectors. Is there a good way within the eCos 
infra structure to handle this? I am porting this from VxWorks. On that 
platform, the "device driver" provided a mechanism to translate the 
interrupt/vector combination into a unique interrupt number that the 
user routine attached to. Then I assume the hardware interrupt decodes 
the interrupt data and does a software interrupt call to the user 
routine. For my actual application, I will not need nearly that many 
interrupts. I'm just not sure what the best way to handle this type of 
situation is.

Thanks
David Brennan
