Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• regex.h
• stdbool.h
• hist.h

Detected Declarations

• struct option
• struct perf_env
• struct sort_entry
• struct evlist
• struct tep_handle
• enum sort_mode
• enum sort_type

Annotation

• Immediate include surface: `regex.h`, `stdbool.h`, `hist.h`.
• Detected declarations: `struct option`, `struct perf_env`, `struct sort_entry`, `struct evlist`, `struct tep_handle`, `enum sort_mode`, `enum sort_type`.
• Atlas domain: Support Tooling And Documentation / tools.
• 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.
