Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• asm/openprom.h

Detected Declarations

• struct device_node
• struct platform_device
• struct dev_archdata
• struct pdev_archdata

Annotated Snippet

	void			*iommu;
	void			*stc;
	void			*host_controller;
	struct platform_device	*op;
	int			numa_node;
};

void of_propagate_archdata(struct platform_device *bus);

	struct resource		resource[PROMREG_MAX];
	unsigned int		irqs[PROMINTR_MAX];
	int			num_irqs;

Annotation

• Immediate include surface: `asm/openprom.h`.
• Detected declarations: `struct device_node`, `struct platform_device`, `struct dev_archdata`, `struct pdev_archdata`.
• Atlas domain: Architecture Layer / arch/sparc.
• 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.
