Re: 64-bit virtual adresses and registers

[Fortes Marcelo]

A Single address space for a multi server Operating on
top of a microkernel don looks like a good idea, how
can i  protect each process server from each other in
a single adress space ?

In fact my question was more related to if any kind of
cpu registers virtualizations can reduce impact over
performance due context change between servers.

In time,(pardon me by my ignorance)Is Eros/CoyotOS IPC
message passing sychronous like L4 or Assyinchronous
like Mach ?

There is any performance comparison between CoyotOS
and Modern L4 Implementations,(FIASCO, L4KA)?

Best wishes
