I'm writing a disk controller driver for a (Sun-3) VMEbus device that nominally wants two (2) interrupt vectors: Vector V is for DMA completion interrupts, and vector V+1 is for status pending interrupts. My question is: How do I cause the interrupt vector table to be set correctly when the device probe routine is called, especially when the interrupt that I force the board to generate is the one at vector V+1? In 4.2BSD, I believe this is done by mucking with 'cvec' and 'uba_hd[numuba].uh_lastiv' in the probe routine. Please reply directly to me, as I am not yet on the sun-spots mailing list.
