AMD DCN 2.0 Display Interrupt Handling Component

An internal piece of AMD's Display Core Next (DCN) 2.0 code inside the amdgpu graphics stack, responsible for routing interrupts (such as vblank and hotplug events) from the display hardware found on Navi-generation Radeon GPUs and Ryzen APUs from around 2019 onward.

recommendation

This is not actually a standalone driver directory; it is a sub-component of the larger AMD display driver that handles interrupt plumbing for DCN 2.0 hardware. It lives or dies with the rest of the amdgpu display code and is not a meaningful candidate for independent removal review.

codex reasoning notes (technical)

Not a driver directory: this is a DCN2.0 IRQ handling subcomponent inside the AMD DRM display stack, not a standalone kernel-bound hardware driver.
