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.

Dependency Surface

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

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#ifndef __BPERF_CGROUP_H
#define __BPERF_CGROUP_H

// These constants impact code size of bperf_cgroup.bpf.c that may result in BPF
// verifier issues. They are exposed to control the size and also to disable BPF
// counters when the number of user events is too large.

// max cgroup hierarchy level: arbitrary
#define BPERF_CGROUP__MAX_LEVELS  10
// max events per cgroup: arbitrary
#define BPERF_CGROUP__MAX_EVENTS  128

#endif /* __BPERF_CGROUP_H */

Annotation

• 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.
