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

• No C-style include directives detected by the generator.

Detected Declarations

• struct sata_gemini
• enum gemini_muxmode

Annotated Snippet

#ifndef SATA_GEMINI_H
#define SATA_GEMINI_H

struct sata_gemini;

enum gemini_muxmode {
	GEMINI_MUXMODE_0 = 0,
	GEMINI_MUXMODE_1,
	GEMINI_MUXMODE_2,
	GEMINI_MUXMODE_3,
};

bool gemini_sata_bridge_enabled(struct sata_gemini *sg, bool is_ata1);
enum gemini_muxmode gemini_sata_get_muxmode(struct sata_gemini *sg);

Annotation

• Detected declarations: `struct sata_gemini`, `enum gemini_muxmode`.
• Atlas domain: Driver Families / drivers/ata.
• 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.
