Annotated Snippet
What: video1394 (a.k.a. "OHCI-1394 Video support" for FireWire)
Date: May 2010 (scheduled), finally removed in kernel v2.6.37
Contact: linux1394-devel@lists.sourceforge.net
Description:
/dev/video1394/* were character device files, one for each FireWire
controller, which were used for isochronous I/O. It was added as an
alternative to raw1394's isochronous I/O functionality which had
performance issues in its first generation. Any video1394 user had
to use raw1394 + libraw1394 too because video1394 did not provide
asynchronous I/O for device discovery and configuration.
Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
firewire-core.

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
