Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/device.h
• linux/videodev2.h
• media/media-entity.h
• media/v4l2-subdev.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#include <linux/device.h>
#include <linux/videodev2.h>
#include <media/media-entity.h>
#include <media/v4l2-subdev.h>

struct v4l2_subdev *fimc_find_remote_sensor(struct media_entity *entity);
void __fimc_vidioc_querycap(struct device *dev, struct v4l2_capability *cap);

Annotation

• Immediate include surface: `linux/device.h`, `linux/videodev2.h`, `media/media-entity.h`, `media/v4l2-subdev.h`.
• Atlas domain: Driver Families / drivers/media.
• Implementation status: source implementation candidate.

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.
