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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• asm/special_insns.h

Detected Declarations

• function arch_xor_init

Annotated Snippet

#include <asm/special_insns.h>

extern struct xor_block_template xor_block_alpha;
extern struct xor_block_template xor_block_alpha_prefetch;

/*
 * Force the use of alpha_prefetch if EV6, as it is significantly faster in the
 * cold cache case.
 */
static __always_inline void __init arch_xor_init(void)
{
	if (implver() == IMPLVER_EV6) {
		xor_force(&xor_block_alpha_prefetch);
	} else {
		xor_register(&xor_block_8regs);
		xor_register(&xor_block_32regs);
		xor_register(&xor_block_alpha);
		xor_register(&xor_block_alpha_prefetch);
	}
}

Annotation

• Immediate include surface: `asm/special_insns.h`.

• 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.
