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 sibling_subcore_state
• struct pt_regs
• function wait_for_subcore_guest_exit

Annotated Snippet

struct sibling_subcore_state {
	unsigned long	flags;
	u8		in_guest[MAX_SUBCORE_PER_CORE];
};

extern void wait_for_subcore_guest_exit(void);
extern void wait_for_tb_resync(void);
#else
static inline void wait_for_subcore_guest_exit(void) { }
static inline void wait_for_tb_resync(void) { }
#endif

struct pt_regs;
extern long hmi_handle_debugtrig(struct pt_regs *regs);

#endif /* __ASM_PPC64_HMI_H__ */

Annotation

• Detected declarations: `struct sibling_subcore_state`, `struct pt_regs`, `function wait_for_subcore_guest_exit`.
• Atlas domain: Architecture Layer / arch/powerpc.
• 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.
