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/smp.h
• asm/numa.h
• asm-generic/topology.h

Detected Declarations

• struct pci_bus
• function arch_fix_phys_package_id

Annotated Snippet

static inline void arch_fix_phys_package_id(int num, u32 slot) { }
#endif /* __ASM_TOPOLOGY_H */

Annotation

• Immediate include surface: `linux/smp.h`, `asm/numa.h`, `asm-generic/topology.h`.
• Detected declarations: `struct pci_bus`, `function arch_fix_phys_package_id`.
• Atlas domain: Architecture Layer / arch/loongarch.
• 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.
