DRM
Digital Rights Management (DRM) is a copyright protection mechanism that restricts the use of digital content through techniques such as encryption and license verification. It is widely applied across digital content platforms including game consoles, streaming services, and e-book distribution systems.

The amdgpu driver interacts with hardware through the DRM subsystem, device trees, and standardized bus interfaces.
The modern DRM framework is jointly composed of the kernel-mode KMS (Kernel Mode Setting) and the user-mode libdrm library.
Sony employs a hardware-bound encryption scheme in which game content is stored in encrypted form, and decryption keys are dynamically delivered via online verification with Sony's servers and stored in a secure enclave.
The Asahi team needed to implement an entirely new memory management backend within the DRM subsystem to accommodate the cache coherency protocol and address space layout unique to Apple hardware.
Technical heritage in the digital age faces unique preservation challenges, including software dependency on specific hardware and operating systems, the transience of data formats, proprietary file formats, DRM encryption, and cloud service dependency.
