What I'm hearing here is that Dell, HP, etc. are designing their firmware to keyfuse any unfused CPU it sees to their firmware automatically, silently, and without any prompting whatsoever. And that AMD apparently has no problem with this.
In no way, shape or form is this a reasonable design. A boot prompt before basically quasi-destroying (for many purposes) a CPU would be the only reasonable thing to do. "This operation is irreversible and will render the CPU unusable in other machines", etc.
I'm wondering if Dell etc. could be sued for this.
>Outside of x86, IBM POWER10 is making a push for enhanced security, so the will need to have a silicon root of trust to enable their security feature set.
If this were true, this would make POWER10 dead-on-arrival in terms of being something Raptor is willing to ship. Comments made by Raptor don't suggest this and suggest they will be able to ship POWER10 eventually, so it doesn't seem likely.
Keyfusing is an excessively brittle technology, can't support key rollover (you're stuck with one key forever, or at best can change it only a couple of times, depending on the size of OTP), and is basically unusable for owner controlled (not vendor controlled) secure boot.
