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

• linux/mm_types.h
• vdso/datapage.h
• asm/barrier.h

Detected Declarations

• struct mips_vdso_image

	void *data;
	unsigned long size;

	unsigned long off_sigreturn;
	unsigned long off_rt_sigreturn;

Annotation

• Immediate include surface: `linux/mm_types.h`, `vdso/datapage.h`, `asm/barrier.h`.
• Detected declarations: `struct mips_vdso_image`.
• Atlas domain: Architecture Layer / arch/mips.
• 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.
