We have created a custom EBSA285-based board, which is running
NetBSD/EBSA285 fine, as the memory mappings are very similar. We have an
extra device on our board, and it uses the XCS0 line into the 21285 as
an interrupt, which is permissible to the 21285. (Interrupt source bit
12). However, we now need to write the device driver and Interrupt
Service Routine, but this is not a conventional interrupt. Does NetBSD
have access to this interrupts source?
if so - how do I set up my interrupt handler in my device driver?
if not - what files do I need to look at changing to include this
interrupt source?
Thanks
Bruce
