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 btcx_riscmem
• struct btcx_skiplist

Annotated Snippet

struct btcx_riscmem {
	unsigned int   size;
	__le32         *cpu;
	__le32         *jmp;
	dma_addr_t     dma;
};

struct btcx_skiplist {
	int start;
	int end;
};

int  btcx_riscmem_alloc(struct pci_dev *pci,
			struct btcx_riscmem *risc,
			unsigned int size);
void btcx_riscmem_free(struct pci_dev *pci,
		       struct btcx_riscmem *risc);

Annotation

• Detected declarations: `struct btcx_riscmem`, `struct btcx_skiplist`.
• Atlas domain: Driver Families / drivers/media.
• 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.
