AMD Has No Plans To Release PSP Code (twitch.tv)

AMD has faced calls from Edward Snowden, Libreboot and the Reddit community to release the source code to the AMD Secure Processor (PSP), a network-capable co-processor which some believe has the capacity to act as a backdoor. But despite some signs earlier that it might consider opening the PSP code at some point, the chip-maker has now confirmed that there hasn't been a change of heart yet. "We have no plans on releasing it to the public," the company executives said in a tech talk (video).

PSP stands for Platform Security Processor, a secure enclave in the processor and AMD's version of the Intel Management Engine.

Quoting from Libreboot:

As such, it has the ability to hide its own program code, scratch RAM, and any data it may have taken and stored from the lesser-privileged x86 system RAM (kernel encryption keys, login data, browsing history, keystrokes, who knows!). To make matters worse, the PSP theoretically has access to the entire system memory space (AMD either will not or cannot deny this, and it would seem to be required to allow the DRM “features” to work as intended), which means that it has at minimum MMIO-based access to the network controllers and any other PCI/PCIe peripherals installed on the system.

AMD is no doubt being bitten on the sack for using third parts code and we again see why everything should be open sources.

Except that's conspiracy-theory reasoning.

If we've learned anything in the last five years or so, it's that's yesterday's wacko conspiracy theory is today's jaw-dropping, fact-checked revelation.
