Modern x86 systems often block #coreboot support due to the silicon Root of Trust (#RoT) mechanisms like Intel #BootGuard or AMD PSB. While Intel platforms have long had public tooling for status checks, AMD users were left without a reliable method.
Michał Kopeć's presentation introduces psb_status, a lightweight script that fills this gap by verifying AMD PSB configuration directly on target hardware.

The talk includes a live demo, outlines future development directions, and opens discussion on how silicon RoT technologies shape the viability of bringing coreboot to new platforms. It is a valuable resource for anyone assessing firmware openness, platform constraints, or coreboot porting potential.

But can it run coreboot? Checking your AMD platform for Platform Secure Boot Developers vPub 0xD

How do you check if your computer can run coreboot? If you have a modern x86 mcchine, the biggest roadblock you may encounter is silicon RoT technology like Intel Boot Guard or AMD PSB. There are tools for checking Intel Boot Guard, but for a long time there hadn't been a publicly available tool for checking AMD PSB. That's why I wrote psb_status, a small script to do just that,.
