AMD has released the latest set of patches for its RDNA 5 GPU IP, initiating the enablement of the Display Core Next (DCN6) display engine. Although the launch of AMD's next‑generation RDNA 5 graphics cards is still a few months away, Linux support is already being developed to ensure every part of the stack is operational before the official release. According to the latest patch noted by Phoronix, the DCN6 display engine is associated with the AMD GFX13, which corresponds to the RDNA 5 GPU family.

AMD's DCN display engine handles a variety of functions, including display output, image scaling, monitor ratio output, pixel manipulation, and much more. This engine is a highly complex component crucial for graphics output in AMD RDNA graphics cards. For this DCN6 version, AMD has introduced new scaling integrity and costing surfaces, a UPSP pre‑scaler to sample 4:2:0 and 4:2:2 content before scaling, and new pixel formats within the display logic.

For the final GPU, this means that modern high‑refresh and high‑resolution gaming will be possible across a range of aspect ratios and configurations, with content being delivered smoothly. However, the final implementation will ultimately depend on what AMD includes in its actual GPU silicon. This marks the first appearance of the new DCN6 display engine, indicating that AMD is getting closer to shipping these RDNA 5 GPUs.

The first wave of shipments will be to its add‑in board partners, who will collaborate with AMD to deliver custom designs, though the timeline for this is still unknown. Interestingly, AMD has provided little public documentation on the DCN versions between DCN 4.2.1 and DCN 6.0.0. There is a single mention of the DCN5 display engine, but it is unclear if AMD decided to skip the DCN5 generation entirely, as the company might be planning interesting developments with DCN6 and chose to move directly to that version.
