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

• nv50.h
• ram.h

Detected Declarations

• function gt215_fb_new

Annotated Snippet

#include "nv50.h"
#include "ram.h"

static const struct nv50_fb_func
gt215_fb = {
	.ram_new = gt215_ram_new,
	.tags = nv20_fb_tags,
	.trap = 0x000d0fff,
};

int
gt215_fb_new(struct nvkm_device *device, enum nvkm_subdev_type type, int inst, struct nvkm_fb **pfb)
{
	return nv50_fb_new_(&gt215_fb, device, type, inst, pfb);
}

Annotation

• Immediate include surface: `nv50.h`, `ram.h`.
• Detected declarations: `function gt215_fb_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.
