Why This File Exists

Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.

• Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.

Dependency Surface

• linux/cpufeature.h
• asm/simd.h
• linux/minmax.h
• linux/sizes.h

Detected Declarations

• function crc64_nvme_arch

Annotated Snippet

likely(may_use_simd())) {
		size_t chunk = len & ~15;

		scoped_ksimd()
			crc = crc64_nvme_neon(crc, p, chunk);

		p += chunk;
		len &= 15;
	}
	return crc64_nvme_generic(crc, p, len);
}

Annotation

• Immediate include surface: `linux/cpufeature.h`, `asm/simd.h`, `linux/minmax.h`, `linux/sizes.h`.
• Detected declarations: `function crc64_nvme_arch`.
• Atlas domain: Kernel Services / lib.
• 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.
