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.

This is great news for DRM content (video and in the future games) that Linux is finally getting the development required to support DRM.
