AMDGPU DCN 2.1 Display Interrupt Support Code

Internal helper code inside the AMD Display Core (DC) component of the amdgpu graphics driver that handles interrupt routing for the DCN 2.1 display engine, found in Renoir and Lucienne APUs (Ryzen 4000/5000 mobile, roughly 2020 era).

recommendation

This is not a standalone driver but a small subcomponent of the larger AMD GPU display stack, providing the interrupt plumbing for the DCN 2.1 display hardware block. It lives and dies with the amdgpu driver as a whole and shouldn't be evaluated in isolation.

codex reasoning notes (technical)

Not a driver directory: DCN2.1 display IRQ support subcomponent inside AMDGPU/DC display code, not a standalone kernel-bound hardware driver.
