Touches IRQ or DMA behavior; this matters for the representative real-device path.

Dependency Surface

No C-style include directives detected by the generator.

Detected Declarations

Annotation

Atlas domain: Support Tooling And Documentation / tools.
Implementation status: atlas-only.
IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
