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 s_mbuf

Annotated Snippet

struct s_mbuf {
	struct s_mbuf	*sm_next ;		/* low level linked list */
	short		sm_off ;			/* offset in m_data */
	u_int		sm_len ;			/* len of data */
#ifdef	PCI
	int		sm_use_count ;
#endif
	char		sm_data[M_SIZE] ;
} ;

typedef struct s_mbuf SMbuf ;

/* mbuf head, to typed data */

#define	smtodoff(x,t,o)	((t)((x)->sm_data + (o)))

Annotation

• Detected declarations: `struct s_mbuf`.
• Atlas domain: Driver Families / drivers/net.
• 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.
