I only saw that in "A Comparison Study of Intel SGX and AMD Memory Encryption", which per my grandparent comment, is not a trustworthy source (they reference the whitepaper, and the whitepaper doesn't say anything about it).

Is that documented in an actual AMD source, or even talk?

As far as I know, the whitepaper is all you will find publicly. It does mention the tweak (on page 4), only if you want the details and don't trust the third-party papers, you will have to reverse-engineer that yourself =]

Fair enough. That's what I assumed, but the HN crowd is pretty resourceful too.
