Well, in theory both AMD and ARM use MOESI so it's not as crazy as it would be with Intel's MESIF. But that's a really scary rabbit hole to be going down and I'd be terrified of memory permissions attacks striking at the boundary there. So probably not worth the risk unless each processor gets its own pool of RAM. https://en.wikipedia.org/wiki/MOESI_protocol https://en.wikipedia.org/wiki/MOESI_protocol
