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
• subdev/gsp.h

Detected Declarations

• function files
• function gm107_fuse_new

Annotated Snippet

#include "priv.h"

#include <subdev/gsp.h>

static u32
gm107_fuse_read(struct nvkm_fuse *fuse, u32 addr)
{
	struct nvkm_device *device = fuse->subdev.device;
	return nvkm_rd32(device, 0x021100 + addr);
}

static const struct nvkm_fuse_func
gm107_fuse = {
	.read = gm107_fuse_read,
};

int
gm107_fuse_new(struct nvkm_device *device, enum nvkm_subdev_type type, int inst,
	       struct nvkm_fuse **pfuse)
{
	if (nvkm_gsp_rm(device->gsp))
		return -ENODEV;

	return nvkm_fuse_new_(&gm107_fuse, device, type, inst, pfuse);
}

Annotation

• Immediate include surface: `priv.h`, `subdev/gsp.h`.
• Detected declarations: `function files`, `function gm107_fuse_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.
