Do governments know which AMD processors are spychips (read: have a PSP)? If yes, can an open data request force disclosure? (lemmy.sdf.org)

I set out to determine which AMD processors do not contain the PSP (which actually compromises your security). Started down this rabbit hole. It’s turned into a shitshow of non-determinism.

So, wouldn’t nation states research which processors are spychips and which are not -- in the interest of national security? If yes, is it just a matter of requesting the info?

It's a security processor built into the main CPU. The AMD and Intel concepts are going to be similar enough that this talk will do:

MINIX is likely the most used OS on earth because it's running inside the x86 processor. tl;dr the processor presented to your operating system isn't the real core of the computer; it's just a virtual machine.

EDIT: I knew there was more, but it's been so long I'd forgotten: https://www.youtube.com/watch?v=jmTwlEh8L7g
