Philips SAA7146 PCI video capture cards (Hexium Orion and Siemens-Nixdorf MXB)
Early-2000s PCI video-capture and frame-grabber cards built around the Philips (later NXP) SAA7146 multimedia bridge chip, including the Hexium Orion/HV-PCI6 industrial frame grabbers and the Siemens-Nixdorf Multimedia eXtension Board. They were used for desktop video capture and industrial machine-vision setups, and have not been sold as new hardware since roughly 2008.
recommendation
Worth keeping but flagging as legacy because the underlying hardware is a roughly 20-year-old PCI capture chip that mostly survives in old industrial and video-capture rigs. Upstream maintainers were still touching the code in 2024 and 2025 (stable backports and a media API adaptation reaching mxb.c), so it is not abandoned, but realistic deployment is small and shrinking. An obsolescence note in the Kconfig would help future cleanup decisions without disrupting the few remaining users.

The directory still receives upstream attention in 2025 via media API adaptation touching mxb.c, so it is not abandoned in-tree.

saa7146-based media PCI code was still being carried in stable backports in 2024, indicating ongoing compatibility maintenance.

LKDDb ties this directory to Hexium HV-PCI6/Orion frame grabber cards and records an earlier temporary move through a deprecated staging location, but the driver remains present in current kernels.

LKDDb ties the same directory to the Siemens-Nixdorf Multimedia eXtension Board and shows it still exists in current kernel Kconfig.

The SAA7146AH is an old Philips/NXP PCI multimedia bridge for desktop-video applications; the surfaced datasheet is from the early-2000s era, consistent with legacy PCI capture hardware rather than new 2025 products.
codex reasoning notes (technical)
Local source inspection via shell showed only legacy PCI V4L2 boards in this directory (Hexium Orion/HV-PCI6 and Siemens-Nixdorf MXB). lore_file_timeline on mxb.c showed non-removal upstream activity through 2025; cited lore URLs came from that MCP result. A broader lore_regex removal search timed out twice, and a web search for lore removal discussion found no hits, so I found no concrete active removal thread. LKDDb URLs were obtained by web search and establish exact board coverage plus the prior deprecated-staging episode. The datasheet URL was obtained by web search and supports that SAA7146 is an early-2000s PCI multimedia bridge. Overall: hardware is legacy and likely only in old industrial/video-capture deployments, but upstream still keeps it building, so keep it with an obsolescence note rather than deprecating for removal now.
