For those who like myself don't know what PSP might be, from the article:
> In short, it’s a coprocessor that has access to just about every part of the computers to which it’s inside. This makes it a prime target for attacks. Introduced around 2013, it’s also entirely closed source, existing as an unknown black box within modern AMD CPUs, which makes the security-conscious highly wary. Operating at a low-level, entirely outside the purview of the main CPU and operating system, the PSP, like the IME, is often considered a potential backdoor into a machine.
- LinuxBender 5y agoI found a few articles that suggest the PSP [0] can be disabled in the BIOS. [1][2] Can anyone here verify this?

- usr1106 5y agoYes I have read the same. My AMD build machine is sold by MSI for gaming. I don't remember having seen such option, there are options for overclocking... Cannot double check now, the machine is in the office and I won't be there before it crashes (knocking on wood) or there is some high priority kernel update.
