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

• umc_v6_0.h
• amdgpu.h

Detected Declarations

• function files

Annotated Snippet

#include "umc_v6_0.h"
#include "amdgpu.h"

static void umc_v6_0_init_registers(struct amdgpu_device *adev)
{
	unsigned i, j;

	for (i = 0; i < 4; i++)
		for (j = 0; j < 4; j++)
			WREG32((i*0x100000 + 0x5010c + j*0x2000)/4, 0x1002);
}

const struct amdgpu_umc_funcs umc_v6_0_funcs = {
	.init_registers = umc_v6_0_init_registers,
};

Annotation

• Immediate include surface: `umc_v6_0.h`, `amdgpu.h`.
• Detected declarations: `function files`.
• 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.
