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/usb.h
• sound/core.h

Detected Declarations

• struct pcm_runtime
• struct hiface_chip

Annotated Snippet

struct hiface_chip {
	struct usb_device *dev;
	struct snd_card *card;
	struct pcm_runtime *pcm;
};
#endif /* HIFACE_CHIP_H */

Annotation

• Immediate include surface: `linux/usb.h`, `sound/core.h`.
• Detected declarations: `struct pcm_runtime`, `struct hiface_chip`.
• Atlas domain: Driver Families / sound/usb.
• 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.
