Internal helper code inside AMD's DRM display stack that implements HDCP (High-bandwidth Digital Content Protection) handshakes for protected video output over HDMI and DisplayPort on AMD GPUs. It is a support library used by the AMD display driver, not a piece of hardware support in its own right.
This is not actually a driver directory; it is a sub-module of the AMD GPU display stack that handles the HDCP content-protection protocol on behalf of the main amdgpu driver. It only exists as part of the larger AMD display code and has no independent lifecycle of its own.

codex reasoning notes (technical)
Not a driver directory: contains AMD DRM display HDCP support module code, an internal helper library within the display stack rather than a standalone kernel-bound hardware driver.
