Phoronix: AMD To Expose More PSP Security Information Under Linux, Including State Of CPU Fuses

Right now under Linux it isn't quick and easy to figure out if the likes of (Transparent) Secure Memory Encryption are enabled and working but a new patch series will more easily expose the security attributes of the AMD Platform Security Processor (PSP) to users on Linux.

Yeah, there's "100% open-source coreboot" on these platforms, but only because most of what coreboot does has been stripped out and replaced by firmware.
