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.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• nvif/mem.h
• nvif/client.h
• nvif/if000a.h

Detected Declarations

• function files
• function nvif_mem_dtor
• function nvif_mem_ctor_type
• function nvif_mem_ctor

Annotated Snippet

if ((mmu->type[i].type & type) == type) {
			ret = nvif_mem_ctor_type(mmu, name, oclass, i, page,
						 size, argv, argc, mem);
		}
	}

	return ret;
}

Annotation

• Immediate include surface: `nvif/mem.h`, `nvif/client.h`, `nvif/if000a.h`.
• Detected declarations: `function files`, `function nvif_mem_dtor`, `function nvif_mem_ctor_type`, `function nvif_mem_ctor`.
• 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.
