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

Detected Declarations

• function gk20a_mc_new

Annotated Snippet

#include "priv.h"

static const struct nvkm_mc_func
gk20a_mc = {
	.init = nv50_mc_init,
	.intr = &gt215_mc_intr,
	.intrs = gk104_mc_intrs,
	.intr_nonstall = true,
	.device = &nv04_mc_device,
	.reset = gk104_mc_reset,
};

int
gk20a_mc_new(struct nvkm_device *device, enum nvkm_subdev_type type, int inst, struct nvkm_mc **pmc)
{
	return nvkm_mc_new_(&gk20a_mc, device, type, inst, pmc);
}

Annotation

• Immediate include surface: `priv.h`.
• Detected declarations: `function gk20a_mc_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.
