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/kdebug.h

Detected Declarations

• struct pt_regs
• struct machine_ops

Annotated Snippet

struct machine_ops {
	void (*restart)(char *cmd);
	void (*halt)(void);
	void (*power_off)(void);
	void (*shutdown)(void);
	void (*crash_shutdown)(struct pt_regs *);
};

extern struct machine_ops machine_ops;

/* arch/sh/kernel/machine_kexec.c */
void native_machine_crash_shutdown(struct pt_regs *regs);

#endif /* __ASM_SH_REBOOT_H */

Annotation

• Immediate include surface: `linux/kdebug.h`.
• Detected declarations: `struct pt_regs`, `struct machine_ops`.
• Atlas domain: Architecture Layer / arch/sh.
• 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.
