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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.

Dependency Surface

• linux/fb.h
• linux/init.h
• video/cmdline.h

Detected Declarations

• function line
• function __video_get_options
• function video_get_options
• export video_get_options
• export __video_get_options

Annotated Snippet

if (!video_options[i]) {
				video_options[i] = options;
				break;
			}
		}
	} else {
		/* global */
		video_option = options;
	}

out:
	return 1;
}
__setup("video=", video_setup);

Annotation

• Immediate include surface: `linux/fb.h`, `linux/init.h`, `video/cmdline.h`.
• Detected declarations: `function line`, `function __video_get_options`, `function video_get_options`, `export video_get_options`, `export __video_get_options`.
• Atlas domain: Driver Families / drivers/video.
• Implementation status: integration 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.
