not being an expert on the powerpc platform, can someone clarify the differences between the above? the current situation is somewhat confusing since there are only two subdirectories under arch/ -- powerpc and ppc -- yet i see constant references to the "ppc64" architecture.
There was some effort a few releases ago to consolidate the two architectures ppc and ppc64 under powerpc. ppc refers, generally, I believe to 32-bit power and ppc64 to 64-bit power. powerpc is the common bits of both (which is all of ppc64, I guess). I think the references you see are just people used to the old nomenclature, or they might mean explicitly the 64-bit powerpc world. It would depend on the context, I presume.
what is the current preferred usage? thanks.
Depends on the context :) I think any of the above terms will get the point across. ppc32 = 32-bit powerpc, ppc64 = 64-bit powerpc, powerpc = powerpc architecture?
