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/dma-mapping.h
• linux/firewire.h

Detected Declarations

• struct iso_packets_buffer

Annotated Snippet

struct iso_packets_buffer {
	struct fw_iso_buffer iso_buffer;
	struct {
		void *buffer;
		unsigned int offset;
	} *packets;
};

int iso_packets_buffer_init(struct iso_packets_buffer *b, struct fw_unit *unit,
			    unsigned int count, unsigned int packet_size,
			    enum dma_data_direction direction);
void iso_packets_buffer_destroy(struct iso_packets_buffer *b,
				struct fw_unit *unit);

Annotation

• Immediate include surface: `linux/dma-mapping.h`, `linux/firewire.h`.
• Detected declarations: `struct iso_packets_buffer`.
• Atlas domain: Driver Families / sound/firewire.
• 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.
