XBUS documentation is not available, but we fully know how to program the SBUS interrupt controller and whatnot. It's all there in the sun4d interrupt and SMP support and it did work just fine at one point. Amusingly the SBUS interrupt stuff on sun4d is a very close sibling to the IMAP/ICLR scheme used on sun4u.
