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/mem.h

Detected Declarations

• struct drm_property_blob
• struct drm_color_lut
• struct nv50_disp
• struct nv50_lut

Annotated Snippet

struct nv50_lut {
	struct nvif_mem mem[2];
};

int nv50_lut_init(struct nv50_disp *, struct nvif_mmu *, struct nv50_lut *);
void nv50_lut_fini(struct nv50_lut *);
u32 nv50_lut_load(struct nv50_lut *, int buffer, struct drm_property_blob *,
		  void (*)(struct drm_color_lut *, int size, void __iomem *));
#endif

Annotation

• Immediate include surface: `nvif/mem.h`.
• Detected declarations: `struct drm_property_blob`, `struct drm_color_lut`, `struct nv50_disp`, `struct nv50_lut`.
• 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.
