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.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/irqreturn.h

Detected Declarations

• struct pt_regs
• function xmon_setup

Annotated Snippet

static inline void xmon_setup(void) { }
#endif

#if defined(CONFIG_XMON) && defined(CONFIG_SMP)
extern int cpus_are_in_xmon(void);
#endif

extern __printf(1, 2) void xmon_printf(const char *format, ...);

#endif /* __KERNEL __ */
#endif /* __ASM_POWERPC_XMON_H */

Annotation

• Immediate include surface: `linux/irqreturn.h`.
• Detected declarations: `struct pt_regs`, `function xmon_setup`.
• Atlas domain: Architecture Layer / arch/powerpc.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
