AMD Van Gogh DCN 3.0.1 display pipeline

Hardware-specific display pipeline code for AMD's Van Gogh APU generation, which uses the Display Core Next 3.0.1 block to drive monitors and internal panels. Van Gogh is best known as the chip powering Valve's Steam Deck handheld, and it also appears in a handful of other small AMD-based devices from the early 2020s onward.

recommendation

It should stay because this is the display engine code for AMD's Van Gogh APU, most famously the chip inside Valve's Steam Deck, which is still being sold new in 2025. Upstream patches were still landing in mid-2025 and into 2026, so the hardware is actively maintained and has no replacement driver outside the amdgpu stack itself.

DCN301 was still receiving upstream patch traffic in July 2025 for a functional display bug fix ('Allow DCN301 to clear update flags').

DCN301-family code was included in a March 10, 2026 amd/display patch series, indicating ongoing upstream maintenance rather than removal.
steamdeck.com
Valve's official Steam Deck tech-specs page showed the device shipping with an AMD APU in 2026, supporting continued new-device deployment in the Steam Deck family.
techpowerup.com
Steam Deck's GPU is identified as Van Gogh and explicitly lists Display Core Next 3.0.1, matching DCN301.
kernel.org
Kernel documentation describes DCN as the active AMD display pipeline architecture family used by amdgpu/display, confirming this directory is a live hardware-generation implementation rather than dead compatibility glue.

codex reasoning notes (technical)

Local shell inspection mapped DCN_VERSION_3_01 to FAMILY_VGH in dc_resource.c, so this hwss directory is the Van Gogh display path. Web search found active DCN301-related amd-gfx traffic on 2025-07-22 and 2026-03-10, and no removal-thread hits in lore-style searches. Valve tech-specs page (web search) shows Steam Deck still shipping, and TechPowerUp (web search) ties Steam Deck to Van Gogh/DCN 3.0.1. Result: niche but current deployed hardware, no natural replacement outside the same amdgpu stack, so keep.
