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

• errno.h
• stdio.h
• string.h
• dirent.h
• sys/types.h
• sys/stat.h
• unistd.h
• stdlib.h
• utils.h

Detected Declarations

• enum energy_freq_attrs
• enum type
• function value_type
• function verify_energy_info
• function main

Annotated Snippet

			sprintf(file_name, "%s/%d/value_desc", path, id);
			f = fopen(file_name, "r");
			FAIL_IF(!f);
			FAIL_IF(fgetc(f) == EOF);
		}
	}

Annotation

• Immediate include surface: `errno.h`, `stdio.h`, `string.h`, `dirent.h`, `sys/types.h`, `sys/stat.h`, `unistd.h`, `stdlib.h`.
• Detected declarations: `enum energy_freq_attrs`, `enum type`, `function value_type`, `function verify_energy_info`, `function main`.
• 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.
