Loongson LS7A and LS2K integrated display controllers

The display and 2D graphics blocks built into Loongson's LS7A1000 and LS7A2000 bridge chips and the LS2K1000 and LS2K2000 SoCs, which are paired with Loongson 3-series MIPS and LoongArch CPUs in Chinese-market desktops, servers, and industrial systems sold from the late 2010s through today.

recommendation

It should stay because the underlying hardware is still actively sold by Loongson in 2025 across desktop, server, and industrial product lines, and the upstream driver is comparatively young with steady maintenance commits landing through 2024 and 2025. There are no signs of removal or deprecation, and it is the canonical way to get accelerated display output on LoongArch and MIPS Loongson systems running mainline Linux.

sources

  1. loongson.cn

    Official Loongson product page says LS7A2000 is targeted at server and personal computer markets and integrates display/GPU functions; evidence it remained a current product in 2025.

  2. loongson.cn

    Official Loongson product page lists an industrial-grade LS7A2000 variant, indicating continuing embedded/industrial deployment rather than legacy-only status.

  3. loongson.cn

    Official Loongson product page lists LS7A1000 as a Loongson 3-family chipset with display capability, matching the older chipset covered by the driver.

  4. loongson.cn

    Official Loongson product page shows the newer LS3A6000 platform was still being marketed recently; this aligns with continued use of companion LS7A-series graphics chipsets in new Loongson systems.

  5. git.kernel.org

    Kernel source Kconfig identifies this as the DRM driver for Loongson Graphics and names LS7A2000, LS7A1000, LS2K2000, and LS2K1000 as covered hardware.

  6. git.kernel.org

    Kernel source pci ID table shows explicit support for Loongson devices 0x7a06 and 0x7a36, i.e. LS7A1000 and LS7A2000 family hardware.

  7. git.kernel.org

    Kernel git history for the directory shows continuing upstream maintenance in 2024-2025, including functional drm/loongson updates rather than only removal/deprecation churn.

codex reasoning notes (technical)

Real driver directory: local exec_command inspection found DRM Kconfig/help text and a PCI driver with Loongson device IDs. Active-upstream signal came from local exec_command git log over this directory (recent functional drm/loongson commits in 2024-2025, no visible removal/deprecation trend); kernel.org tree/log URLs are canonical recall anchors for those inspected files. Deployment evidence came from web search results opening official loongson.cn product pages for LS7A1000/LS7A2000 and industrial LS7A2000, which indicates the hardware family was still sold into desktop/server and embedded niches in 2025. Because the hardware is still marketed and the upstream driver is young and maintained, this should be kept, not deprecated.
