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

• amdgpu.h
• df_v4_6_2.h

Detected Declarations

• function files

Annotated Snippet

#include "amdgpu.h"
#include "df_v4_6_2.h"

static bool df_v4_6_2_query_ras_poison_mode(struct amdgpu_device *adev)
{
	/* return true since related regs are inaccessible */
	return true;
}

const struct amdgpu_df_funcs df_v4_6_2_funcs = {
	.query_ras_poison_mode = df_v4_6_2_query_ras_poison_mode,
};

Annotation

• Immediate include surface: `amdgpu.h`, `df_v4_6_2.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.
