Hubris is a part of booting on our systems in that it executes on both our root of trust and on our service processor -- but both of these execute long before the host CPU. To understand how we boot our host CPU (AMD Milan) on an Oxide compute sled, see my OSFC 2022 talk[0][1], as well as the episode of our Oxide and Friends podcast on holistic boot.[2]

Thanks a lot for sharing! I ended up watching the referenced "It's Time for Operating Systems to Rediscover Hardware" talk as well. Fascinating stuff.
