AMDGPU TMZ + HDCP Should Allow Widevine DRM To Behave Nicely With AMD Linux Systems

Phoronix | Sept. 19, 2020, 3:15 p.m. | Original

Coming together this year for the mainline Linux kernel was the AMDGPU Trusted Memory Zone (TMZ) capability for encrypted video memory support with Radeon GPUs. This topic was talked about at this week's XDC2020 conference.

AMDGPU TMZ prevents unauthorized applications from accessing the encrypted/trusted memory of an application. TMZ protects both reads and writes while leveraging an AES cipher. But while discrete Radeon GPUs can also support TMZ, for now the AMD Linux developers have just been focused on the capability for their APU platforms

After working on getting the Zink OpenGL-over-Vulkan driver up to OpenGL 4.6 with still pending patches, former Samsung OSG engineer Mike Blumenkrantz has been making remarkable progress on the performance aspect as well.

This generic Mesa OpenGL implementation that works atop Vulkan drivers is about to see much better performance. Blumenkrantz recently commented the performance was turning out better than expected but that was for micro-benchmarks. But now with more optimizations he is achieving even better results.
