Ditto. I was under the impression it was modeled after the KA10 scheme. I
don't remember who told me that, probably somebody from CSS, but I have no
idea whom. As I think you remember when you asked about it a while ago, I
sent some probes to a few of folks from the 11 group but all of them
disavowed any knowledge of it.
One of the questions I always had was since M[TF]P[IDS] instructions were
not created until the 40 and 45 class processors, how did Ken get the
information to/fr the other address space. I >>think<< the KT has a funky
memory window (that I never really looked into in any detail), I assume
the KS must have done something similar.
