AMD DCN 3.0 Display Interrupt Support Code

Internal helper code for the third-generation AMD Display Core Next (DCN 3.0) display engine, which routes hardware interrupts (vblank, page-flip, hotplug, and similar events) for the display controllers built into RDNA 2 GPUs such as the Radeon RX 6000 series and the integrated graphics in newer Ryzen APUs.

recommendation

This is not actually a standalone driver directory; it is a small slice of interrupt-handling source code that lives inside AMD's larger Display Core (DC) stack, supporting the DCN 3.0 display hardware found in RDNA 2 era GPUs like the Radeon RX 6000 series. It only makes sense as part of the broader amdgpu driver and cannot be evaluated for keep-or-remove on its own.

codex reasoning notes (technical)

Not a driver directory: DCN3.0 display IRQ support code nested inside the AMD DC display stack, with no standalone kernel-bound hardware driver entry point in this directory.
