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/hw_breakpoint.h

Detected Declarations

• struct pt_regs
• function debugger
• function debugger_ipi
• function debugger_bpt
• function debugger_sstep
• function debugger_iabr_match
• function debugger_break_match
• function debugger_fault_handler

Annotation

• Immediate include surface: `asm/hw_breakpoint.h`.
• Detected declarations: `struct pt_regs`, `function debugger`, `function debugger_ipi`, `function debugger_bpt`, `function debugger_sstep`, `function debugger_iabr_match`, `function debugger_break_match`, `function debugger_fault_handler`.
• 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.
