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

• asm/ptrace.h
• asm/lppaca.h
• asm/firmware.h

Detected Declarations

• function ppc_set_pmu_inuse
• function ppc_get_pmu_inuse
• function ppc_set_pmu_inuse

Annotated Snippet

static inline void ppc_set_pmu_inuse(int inuse) { }

#endif /* __KERNEL__ */
#endif /* _POWERPC_PMC_H */

Annotation

• Immediate include surface: `asm/ptrace.h`, `asm/lppaca.h`, `asm/firmware.h`.
• Detected declarations: `function ppc_set_pmu_inuse`, `function ppc_get_pmu_inuse`, `function ppc_set_pmu_inuse`.
• 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.
