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-generic/kprobes.h
• asm/inst.h
• asm/cacheflush.h

Detected Declarations

• struct arch_specific_insn
• struct prev_kprobe
• struct kprobe_ctlblk
• function kprobe_breakpoint_handler
• function kprobe_singlestep_handler

Annotation

• Immediate include surface: `asm-generic/kprobes.h`, `asm/inst.h`, `asm/cacheflush.h`.
• Detected declarations: `struct arch_specific_insn`, `struct prev_kprobe`, `struct kprobe_ctlblk`, `function kprobe_breakpoint_handler`, `function kprobe_singlestep_handler`.
• 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.
