Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• xen/swiotlb-xen.h
• xen/xen-ops.h

Detected Declarations

• function xen_setup_dma_ops

Annotated Snippet

#ifndef _ASM_ARM_XEN_OPS_H
#define _ASM_ARM_XEN_OPS_H

#include <xen/swiotlb-xen.h>
#include <xen/xen-ops.h>

static inline void xen_setup_dma_ops(struct device *dev)
{
#ifdef CONFIG_XEN
	if (xen_swiotlb_detect())
		dev->dma_ops = &xen_swiotlb_dma_ops;
#endif
}

#endif /* _ASM_ARM_XEN_OPS_H */

Annotation

• Immediate include surface: `xen/swiotlb-xen.h`, `xen/xen-ops.h`.
• Detected declarations: `function xen_setup_dma_ops`.
• Atlas domain: Repository Root And Misc / include.
• 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.
