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

• nvif/object.h

Detected Declarations

• struct nvif_device
• struct nvif_user
• struct nvif_user_func

Annotated Snippet

struct nvif_user {
	const struct nvif_user_func *func;
	struct nvif_object object;
};

struct nvif_user_func {
	void (*doorbell)(struct nvif_user *, u32 token);
	u64 (*time)(struct nvif_user *);
};

int nvif_user_ctor(struct nvif_device *, const char *name);
void nvif_user_dtor(struct nvif_device *);

extern const struct nvif_user_func nvif_userc361;
#endif

Annotation

• Immediate include surface: `nvif/object.h`.
• Detected declarations: `struct nvif_device`, `struct nvif_user`, `struct nvif_user_func`.
• Atlas domain: Driver Families / drivers/gpu.
• 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.
