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

• drm/drm_suballoc.h

Detected Declarations

• struct xe_bo
• struct xe_sa_manager

Annotated Snippet

struct xe_sa_manager {
	struct drm_suballoc_manager base;
	struct xe_bo *bo;
	struct xe_bo *shadow;
	/** @swap_guard: Timeline guard updating @bo and @shadow */
	struct mutex swap_guard;
	void *cpu_ptr;
	bool is_iomem;
};

Annotation

• Immediate include surface: `drm/drm_suballoc.h`.
• Detected declarations: `struct xe_bo`, `struct xe_sa_manager`.
• 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.
