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

• priv.h

Detected Declarations

• struct nv50_fb
• struct nv50_fb_func

Annotated Snippet

struct nv50_fb {
	const struct nv50_fb_func *func;
	struct nvkm_fb base;
};

struct nv50_fb_func {
	int (*ram_new)(struct nvkm_fb *, struct nvkm_ram **);
	u32 (*tags)(struct nvkm_fb *);
	u32 trap;
};

int nv50_fb_new_(const struct nv50_fb_func *, struct nvkm_device *, enum nvkm_subdev_type, int,
		 struct nvkm_fb **pfb);
#endif

Annotation

• Immediate include surface: `priv.h`.
• Detected declarations: `struct nv50_fb`, `struct nv50_fb_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.
