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 based on ARM TrustZone tech, and is (probably amongst other things) a tpm2 implementation within the SoC that also gates silicon initialisation (the x86 cores will not spin up without it).

I'm not sure it could be thought of as equivalent to Intel Management Engine in terms of it's overall capability, however.
