AMD "Trusted Memory Zone" Encrypted vRAM Support Coming To Their Linux GPU Driver

Filed under

AMD Trusted Memory Zone support is a new feature being worked on for their open-source graphics driver that works in conjunction with the graphics hardware for being able to encrypt portions of the video memory.

Trusted Memory Zone (TMZ) support appears to be present going back to the original Vega graphics processors but this is the first time we're seeing it implemented on the Linux side. Trusted Memory Zone protects the contents of TMZ'ed pages from being read by the CPU (non-GPU) clients and fend off writes to the protected pages. AMD TMZ support is being used to offer secure buffer object support on Linux.
