There’s a project which collects ACPI tables from Microsoft Surface devices. It appears to be a Linux distro for Surface, unclear how they’re being used.

I wish OEMs had hashes for the ACPI tables they ship. I wish FWTS or CHIPSEC or someone else had some security-centric test tool that’d examine these ACPI tables for malware. There is this tool:

And there’s also a collection of ACPI tables on:
