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

• No C-style include directives detected by the generator.

Detected Declarations

• struct frame_record
• struct frame_record_meta

Annotated Snippet

struct frame_record {
	u64 fp;
	u64 lr;
};

/*
 * A metadata frame record indicating a special unwind.
 * The record::{fp,lr} fields must be zero to indicate the presence of
 * metadata.
 */
struct frame_record_meta {
	struct frame_record record;
	u64 type;
};
#endif /* __ASSEMBLER__ */

#endif /* __ASM_STACKTRACE_FRAME_H */

Annotation

• Detected declarations: `struct frame_record`, `struct frame_record_meta`.
• Atlas domain: Architecture Layer / arch/arm64.
• 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.
