HiSilicon HiBMC iBMC DisplayPort output
The DisplayPort output portion of Huawei's HiBMC/iBMC baseboard management controller, the small management chip on Huawei server motherboards that provides a basic console video signal and remote KVM-over-IP for administrators. It drives the DP connector (or a virtual sink when no monitor is plugged in) on iBMC-equipped servers such as the TaiShan 200 line, which Huawei still sells today.
recommendation
It should stay in the kernel because the DisplayPort block of Huawei's iBMC server-management chip is still seeing active bug-fix patches in 2025 and 2026, including link-detection and link-capability fixes flowing through drm-misc-fixes. The hardware ships in current Huawei TaiShan-class servers, so even though deployment volume is modest, this is current, maintained code rather than a legacy artifact.

August 13, 2025 hibmc patch states the chip supports KVM over IP and must handle cases with no physical connector, evidencing real BMC/KVM deployment use.

Huawei TaiShan 200 server documentation updated in 2025 describes iBMC as the remote server-management subsystem with virtual KVM/media, supporting ongoing shipment/deployment of iBMC-equipped servers.
codex reasoning notes (technical)
Local tree inspection via exec_command showed this directory is compiled into `hibmc-drm` from `drivers/gpu/drm/hisilicon/hibmc/Makefile`, so it is real driver code, not a helper-only subtree. All cited URLs were obtained via web search_query snippets. The lore/spinics results show fresh 2025-2026 DP bug-fix traffic and no removal/deprecation series, so deprecation is not justified. Deployment appears niche but current: HiBMC/iBMC is tied to Huawei server remote-management/KVM use rather than mainstream client GPUs, so keep the driver but treat it as low-volume, vendor-specific hardware.
