Yeah, I think that's called DIG64. They had a reasonably nice HW timer setup,
but not so nice for NUMA synchronization as the one we built into the
[[Deleted by IP Police]] chipset. That had snapshot and delta adjust logic,
to synchronize nodes to one interconnect bus clock cycle. Too bad that
project was canned....
