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

• engine/bsp.h
• nvif/class.h

Detected Declarations

• function g84_bsp_new

Annotated Snippet

#include <nvif/class.h>

	.fifo_val = 0x1111,
	.unkd28 = 0x90044,

		{}
	}
};

	    struct nvkm_engine **pengine)

}

Annotation

• Immediate include surface: `engine/bsp.h`, `nvif/class.h`.
• Detected declarations: `function g84_bsp_new`.
• 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.
