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

• linux/lockdep.h

Detected Declarations

• struct amdgpu_device
• function amdgpu_lockdep_init
• function amdgpu_lockdep_set_class

Annotated Snippet

static inline int amdgpu_lockdep_init(void) { return 0; }
static inline void amdgpu_lockdep_set_class(struct amdgpu_device *adev) {}

#endif /* CONFIG_LOCKDEP */

#endif /* __AMDGPU_LOCKDEP_H__ */

Annotation

• Immediate include surface: `linux/lockdep.h`.
• Detected declarations: `struct amdgpu_device`, `function amdgpu_lockdep_init`, `function amdgpu_lockdep_set_class`.
• 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.
