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/bitops.h
• linux/threads.h
• linux/cpumask.h

Detected Declarations

• function smp_send_all_nop

Annotated Snippet

static inline void smp_send_all_nop(void) { return; }

#endif

#define NO_PROC_ID		0xFF		/* No processor magic marker */
#define ANY_PROC_ID		0xFF		/* Any processor magic marker */
int __cpu_disable(void);
void __cpu_die(unsigned int cpu);

#endif /*  __ASM_SMP_H */

Annotation

• Immediate include surface: `linux/bitops.h`, `linux/threads.h`, `linux/cpumask.h`.
• Detected declarations: `function smp_send_all_nop`.
• Atlas domain: Architecture Layer / arch/parisc.
• 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.
