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

• No C-style include directives detected by the generator.

Detected Declarations

• struct vrfb
• function omap_vrfb_supported
• function omap_vrfb_request_ctx
• function omap_vrfb_release_ctx
• function omap_vrfb_max_height
• function omap_vrfb_setup
• function omap_vrfb_restore_context

Annotation

• Detected declarations: `struct vrfb`, `function omap_vrfb_supported`, `function omap_vrfb_request_ctx`, `function omap_vrfb_release_ctx`, `function omap_vrfb_max_height`, `function omap_vrfb_setup`, `function omap_vrfb_restore_context`.
• 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.
