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

• No C-style include directives detected by the generator.

Detected Declarations

• struct thread_struct

Annotated Snippet

#ifndef _ASM_SWITCH_TO_H
#define _ASM_SWITCH_TO_H

struct thread_struct;

extern struct task_struct *__switch_to(struct task_struct *,
	struct task_struct *,
	struct task_struct *);

#define switch_to(p, n, r) do {\
	r = __switch_to((p), (n), (r));\
} while (0)

#endif /* _ASM_SWITCH_TO_H */

Annotation

• Detected declarations: `struct thread_struct`.
• Atlas domain: Architecture Layer / arch/hexagon.
• 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.
