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.

Annotation

• Immediate include surface: `../../lib/cpupower_intern.h`, `../../lib/acpi_cppc.h`, `../../lib/cpufreq.h`, `../../lib/cpuidle.h`, `../../lib/cpupower.h`, `../../lib/powercap.h`.
• Detected declarations: `struct cpufreq_policy`, `struct cpufreq_available_governors`, `struct cpufreq_available_frequencies`, `struct cpufreq_affected_cpus`, `struct cpufreq_stats`, `struct cpupower_topology`, `struct cpuid_core_info`, `struct powercap_zone`, `enum acpi_cppc_value`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: atlas-only.

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.
