The PS5 has many kernel devices that can be accessed through [[IOCTL]]. Some of them have usermode module equivalents, some like "sbl" consist in [[Secure Modules]] and some like "camera" make use of a dedicated firmware stored in kernel memory.

MP3 consists of the Trusted Execution Environment (TEE) running on the AMD Platform Security Processor (PSP/SP). Its primary function is Digital Rights Management (DRM) via [https://www.microsoft.com/playready/features/EnhancedContentProtection.aspx PlayReady SL3000]. In userspace, the libSceTEEClient library is used for interfacing with it, which internally uses /dev/mp3 to load secure binaries (sbins) and establish sessions. Below are known commands.
