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 acpm_xfer
• struct acpm_handle

Annotated Snippet

	const u32 *txd __counted_by_ptr(txcnt);
	u32 *rxd __counted_by_ptr(rxcnt);
	size_t txcnt;
	size_t rxcnt;
	unsigned int acpm_chan_id;
};

void acpm_set_xfer(struct acpm_xfer *xfer, u32 *cmd, size_t cmdcnt,
		   unsigned int acpm_chan_id, bool response);
int acpm_do_xfer(struct acpm_handle *handle,
		 const struct acpm_xfer *xfer);

Annotation

• Detected declarations: `struct acpm_xfer`, `struct acpm_handle`.
• Atlas domain: Driver Families / drivers/firmware.
• 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.
