For everybody wondering: 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.
- dmead 9y agothanks, i was thinking about handheld games and getting pretty confused.
- Sharlin 9y agoI wondered when AMD had acquired the source code for Paint Shop Pro.

- growt 9y agoAnd I was thinking about Payment Service Providers. I guess every domain has their PSP :)
- leeoniya 9y agobasically same thing for any baseband processor - they have full DMA and there's nothing you can do about it.
- wolfgke 9y ago> they have full DMA and there's nothing you can do about it. At least the Neo900 developers tried to isolate the baseband processor as far as possible: > http://neo900.org/faq#privacy http://neo900.org/faq#privacy
- robin_reala 9y agoWell, that’s not true. Sure, connect it over PCIE and all bets are off, but connect it over USB and you should be fine. If you’re being super careful buy a Bluetooth 3G module.
