So to rephrase your question.... What defines an architecture, and what defines a platform?

That is for deletion all data structures and state associated with the processor are thrown away (the CPU is unconfigured from the system). But yea, i'm sort of guessing you don't need to do that.
Well, even without a simulation, I think we shouldn't unconfigure the cpu. Since the processors will be turned back on again when they are needed, I think we should rather keep all the associated structures in order to save some time when turning them on. So this means we shouldn't use DR and stick to cpu_offline and the like, right? Thanks, thomas -Eric
