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

• stdio.h
• linux/types.h

Detected Declarations

• struct evsel
• struct perf_read_values

Annotated Snippet

	int threads;
	int threads_max;
	u32 *pid, *tid;
	int num_counters;
	int counters_max;
	struct evsel **counters;
	u64 **value;
};

int perf_read_values_init(struct perf_read_values *values);
void perf_read_values_destroy(struct perf_read_values *values);

int perf_read_values_add_value(struct perf_read_values *values,
				u32 pid, u32 tid,
				struct evsel *evsel, u64 value);

void perf_read_values_display(FILE *fp, struct perf_read_values *values,
			      int raw);

Annotation

• Immediate include surface: `stdio.h`, `linux/types.h`.
• Detected declarations: `struct evsel`, `struct perf_read_values`.
• 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.
