AMD DCN 2.0 Display Pipe and Plane block (Navi 10/14 Radeon RX 5000)
Hardware programming for the Display Pipe and Plane block inside AMD's second-generation Display Core Next, the on-chip display engine used by Navi 10 and Navi 14 GPUs. These are the Radeon RX 5000 series and Radeon Pro W5000 workstation cards that AMD shipped from 2019 through 2020 and still supports today.
recommendation
It should stay because this code drives the display pipeline on AMD's Navi 10 and Navi 14 GPUs (the Radeon RX 5000 and Radeon Pro W5000 families from 2019-2020), which are still in widespread use and still receiving AMD driver updates. Upstream activity is healthy: the amd/display tree was still landing changes in early 2025, and there is no sign of a removal effort.

Kernel AMD hardware list maps DCN 2.0.0 to NAVI10 and NAVI14 products such as Radeon RX 5000 / Radeon Pro W5000-family GPUs.

AMD display code is part of the amdgpu Display Core, and DPP is a real display-pipeline hardware block within that driver stack.
- lists.openwall.net
The March 28, 2025 DRM pull for Linux 6.15-rc1 still carried multiple drm/amd/display changes, including Samson Tam's 'Move SPL to a new path', consistent with ongoing upstream maintenance rather than retirement.
- amd.com
AMD still publishes current RX 5500 XT driver downloads, indicating the DCN 2.0-era hardware remains actively deployed and supported.
codex reasoning notes (technical)
Not an early-exit case: this directory contains ASIC-specific DPP hardware programming code inside amdgpu DC. `sed` on dcn20_dpp.h identified it as the DCN20 DPP block; `git -c safe.directory=... log` on the path showed substantive touches through 2025-01-23 and no local sign of abandonment. URLs were obtained via `web.search_query` (kernel docs, AMD support, openwall archive). I did not find a removal-thread hit in the available web searches; absence-of-removal is an inference from recent upstream amd/display traffic plus the lack of removal results, so I kept confidence below 0.8. 'Still sold new in 2025' is assessed false because the cited product evidence is ongoing driver support rather than active current-product marketing; DCN 2.0 parts are older 2019-2020 Navi-era GPUs, but deployments remain medium due to continuing support.
