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/types.h
• linux/bits.h

Detected Declarations

• struct brcmf_xtlv
• enum brcmf_xtlv_option

Annotated Snippet

struct brcmf_xtlv {
	u16 id;
	u16 len;
	u8 data[];
};

enum brcmf_xtlv_option {
	BRCMF_XTLV_OPTION_ALIGN32 = BIT(0),
	BRCMF_XTLV_OPTION_IDU8 = BIT(1),
	BRCMF_XTLV_OPTION_LENU8 = BIT(2),
};

int brcmf_xtlv_data_size(int dlen, u16 opts);
void brcmf_xtlv_pack_header(struct brcmf_xtlv *xtlv, u16 id, u16 len,
			    const u8 *data, u16 opts);

#endif /* __BRCMF_XTLV_H */

Annotation

• Immediate include surface: `linux/types.h`, `linux/bits.h`.
• Detected declarations: `struct brcmf_xtlv`, `enum brcmf_xtlv_option`.
• 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.
