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 hva_buffer

Annotated Snippet

struct hva_buffer {
	const char		*name;
	dma_addr_t		paddr;
	void			*vaddr;
	u32			size;
};

int hva_mem_alloc(struct hva_ctx *ctx,
		  __u32 size,
		  const char *name,
		  struct hva_buffer **buf);

void hva_mem_free(struct hva_ctx *ctx,
		  struct hva_buffer *buf);

#endif /* HVA_MEM_H */

Annotation

• Detected declarations: `struct hva_buffer`.
• 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.
