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

• media/videobuf2-v4l2.h
• linux/dma-mapping.h

Detected Declarations

• function vb2_dma_contig_plane_dma_addr
• function vb2_dma_contig_clear_max_seg_size

Annotated Snippet

static inline void vb2_dma_contig_clear_max_seg_size(struct device *dev) { }

extern const struct vb2_mem_ops vb2_dma_contig_memops;

#endif

Annotation

• Immediate include surface: `media/videobuf2-v4l2.h`, `linux/dma-mapping.h`.
• Detected declarations: `function vb2_dma_contig_plane_dma_addr`, `function vb2_dma_contig_clear_max_seg_size`.
• 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.
