AMD DCN 2.0 HUBP display hardware block

Code for the Hub Pipe (HUBP) hardware block in AMD's second-generation Display Core Next (DCN 2.0) display engine, which is the part of Navi-era Radeon GPUs and APUs that fetches pixel data from memory into the display pipeline. It is one building block of the larger AMD display stack rather than a device anyone binds to directly.

recommendation

This is not a standalone driver but an internal component of AMD's Display Core (DC) inside the amdgpu graphics driver. It implements the Hub Pipe (HUBP) block for the DCN 2.0 display engine used in Navi-generation GPUs (Radeon RX 5000 series and related APUs), and only ships as part of the larger amdgpu module.

codex reasoning notes (technical)

Not a driver directory: internal AMD display DCN2.0 HUBP hardware-block implementation within amdgpu/DC, not a standalone kernel-bound device driver.
