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

• string.h
• linux/compiler.h
• ../debug.h
• ../disasm.h
• ../map.h
• ../maps.h
• ../symbol.h
• ../thread.h
• ../annotate.h
• ../annotate-data.h

Detected Declarations

• function s390_call__parse
• function s390_mov__parse
• function s390__cpuid_parse

Annotated Snippet

if (s390__cpuid_parse(arch, cpuid)) {
			errno = SYMBOL_ANNOTATE_ERRNO__ARCH_INIT_CPUID_PARSING;
			return NULL;
		}
	}
	arch->objdump.comment_char = '#';
	return arch;
}

Annotation

• Immediate include surface: `string.h`, `linux/compiler.h`, `../debug.h`, `../disasm.h`, `../map.h`, `../maps.h`, `../symbol.h`, `../thread.h`.
• Detected declarations: `function s390_call__parse`, `function s390_mov__parse`, `function s390__cpuid_parse`.
• 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.
