Fujitsu MB862xx Carmine, Coral, and Lime embedded graphics controllers

A family of Fujitsu graphics display controllers (MB86293/4/5/6/7, marketed as Carmine, Coral-P/PA, and Lime) sold from the early 2000s for embedded uses like in-car navigation, instrument clusters, infotainment, and game consoles. The chips attach over PCI or via device tree on embedded boards and provide framebuffer output.

recommendation

Worth keeping but flagging as niche. The MB86297 is now marked obsolete by distributors and the hardware only really lives on in older automotive and industrial deployments, but the upstream code still saw real maintenance activity in 2025, including a correctness fix from a Vivo engineer and a patch making CONFIG_FB_DEVICE optional. That ongoing care argues for retention with a clear note about the legacy embedded scope rather than deprecation.

sources

  1. lore.kernel.org

    The driver still receives upstream attention in 2025; a v3 patch touched mb862xxfbdrv.c to make CONFIG_FB_DEVICE optional rather than proposing removal.

  2. lore.kernel.org

    Recent 2025 traffic also includes a correctness fix in mb862xxfb, indicating maintenance rather than abandonment.

  3. cateee.net

    LKDDb shows CONFIG_FB_MB862XX is still present upstream and covers Fujitsu MB86295S/MB86296S/MB86297A plus OF compatibles MB86276/MB86277/MB86293/MB86294.

  4. pr.fujitsu.com

    Fujitsu positioned MB86293 as an embedded graphics controller for vehicle navigation systems and video game consoles, indicating an early-2000s embedded market.

  5. digikey.com

    A DigiKey-hosted Fujitsu document describes MB86297/MB86276 as graphics display controllers for automotive applications such as navigation, instrument panels, and infotainment, plus other embedded uses.

  6. digikey.com

    A current distributor listing for MB86297 shows the part status as Obsolete and no longer manufactured, supporting that this family is not in new mainstream sales.

codex reasoning notes (technical)

Real driver, not an early-exit case. Local source inspection via shell identified Fujitsu Carmine/Coral-P(A)/Lime support and OF/PCI bindings. lore_file_timeline on mb862xxfbdrv.c showed substantial recent activity through 2025, and the cited lore URLs came from that MCP result; this argues against deprecate/remove. Web search found LKDDb coverage, an official Fujitsu 2002 launch page, a DigiKey-hosted Fujitsu family document for embedded automotive/industrial use, and a current DigiKey product page marking MB86297 obsolete. Conclusion: hardware is legacy and niche today, likely only in old embedded/industrial/automotive deployments, but upstream still sees enough fixup/build/API traffic that the right posture is keep-annotate rather than deprecate.
