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

• stdbool.h

Detected Declarations

• struct evsel
• struct list_head

Annotated Snippet

#ifndef _TOPDOWN_H
#define _TOPDOWN_H 1

#include <stdbool.h>

struct evsel;
struct list_head;

bool topdown_sys_has_perf_metrics(void);
bool arch_is_topdown_slots(const struct evsel *evsel);
bool arch_is_topdown_metrics(const struct evsel *evsel);
int topdown_insert_slots_event(struct list_head *list, int idx, struct evsel *metric_event);

#endif

Annotation

• Immediate include surface: `stdbool.h`.
• Detected declarations: `struct evsel`, `struct list_head`.
• 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.
