@david_chisnall@infosec.exchange @mjg59@nondeterministic.computer That's good to hear (and of course you're right, Sphere took the Pluton IP from xbox peripherals but afaik Sphere was the first product release for IOT device OEMs before it was then licensed to AMD and offered to PC OEMs) I worked on some fTPM ARM stuff before Sphere and it's a strange rollback given that pluton is its own hardware IP and fTPM is just a piece of software running in yet another CPU mode. So maybe the LTSC cycle alignment is just a coincidence.

@cubeos@hachyderm.io @mjg59@nondeterministic.computer I don’t know why they’d do this. For another project I had to review a bunch of hardware roots of trust available commercially and Pluton was so far ahead of them it was hilarious.

@cubeos@hachyderm.io @david_chisnall@infosec.exchange @mjg59@nondeterministic.computer only a "hardware IP" with intel, right? on qcom it's an SPU applet. on amd it's also some PSP thing i think?
