Right, the chipset register is mainly used to program the contents of SMM.There is a single access pin that has effectively the same semantics as setting the chipset register.It's not a per-CPU setting--that's the point. You can't have one CPU reading SMM memory at the exactly same time as accessing VGA.But I guess you can never have two simultaneous accesses anyway so perhaps it's splitting hairs :-)
Exactly - it just works.btw, a way to implement it would be to have two memory maps, one for SMM and one for non-SMM, and select between them based on the CPU mode.
