> What happened to Project X (supposedly coreboot++ for latest AMD CPUs)?
I don't recall what you're referring to specifically, maybe this was a thing before I started at Oxide. I do know that we deliberately decided to not go with coreboot. I believe the equivalent component would be phbl[1]. It boots illumos directly. Bryan gave a talk about how we boot[1][2] with more reasoning and context.
> Does Oxide attempt to sandbox, completely remove or 'verify as benign' aspects like the PSP?
The general attitude is still "remove or work around every binary blob possible," but the PSP is unfortunately not able to be worked around.

We fully intend to do this, by the way. Just haven't yet. It'll come.
