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

• dc_types.h

Detected Declarations

• struct dc_context
• struct dio
• struct dio_funcs
• struct dio

Annotated Snippet

struct dio_funcs {
	void (*mem_pwr_ctrl)(struct dio *dio, bool enable_i2c_light_sleep);
};

struct dio {
	const struct dio_funcs *funcs;
	struct dc_context *ctx;
};

Annotation

• Immediate include surface: `dc_types.h`.
• Detected declarations: `struct dc_context`, `struct dio`, `struct dio_funcs`, `struct dio`.
• Atlas domain: Driver Families / drivers/gpu.
• 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.
