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

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

Detected Declarations

• struct perf_bpf_filter_entry
• struct idx_hash_key
• enum perf_bpf_filter_op
• enum perf_bpf_filter_term

Annotated Snippet

struct perf_bpf_filter_entry {
	enum perf_bpf_filter_op op;
	__u32 part; /* sub-sample type info when it has multiple values */
	enum perf_bpf_filter_term term;
	__u64 value;
};

struct idx_hash_key {
	__u64 evt_id;
	__u32 tgid;
	__u32 reserved;
};

Annotation

• Detected declarations: `struct perf_bpf_filter_entry`, `struct idx_hash_key`, `enum perf_bpf_filter_op`, `enum perf_bpf_filter_term`.
• 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.
