Digiteq Automotive FrameGrabber 4 PCIe video capture cards
A PCIe frame-grabber card from Czech vendor Digiteq Automotive that captures video from automotive camera links such as FPD-Link III and GMSL1/2/3, used by car-industry engineers to record and analyse feeds from in-vehicle cameras during development and testing. FrameGrabber 4 is the current generation, succeeding Digiteq's older Modular Frame Grabber (MGB) line.
recommendation
It should stay in the kernel because the hardware is actively sold by Digiteq Automotive in 2025 and the driver is under steady upstream maintenance, with feature work as recent as early 2026 adding support for new GMSL1 and GMSL3 coaxial interface modules. Deployments are niche — automotive camera testing and infotainment lab rigs — but there is no in-tree replacement and no sign of deprecation.

codex reasoning notes (technical)
Shell `rg` on local sources (`Kconfig`, `mgb4_core.c`) identified Digiteq Automotive, PCI IDs T100/T200, and the FG4/MGB4 family. Local `git -c safe.directory=... log -- drivers/media/pci/mgb4` showed active 2024-2026 maintenance with recent feature work (for example GMSL1 and GMSL3 coaxial support in January 2026); I cite the canonical kernel.org log URL for that history (canonical recall). `web.search_query` found the kernel doc and Digiteq product pages; `web.open`/`find` confirmed the hardware is still marketed in 2026 and that MGB was superseded by FG4 hardware, not by another in-tree Linux driver. This is niche automotive infotainment/test equipment, so deployments are low, but the driver is active and should be kept.
