Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
Touches IRQ or DMA behavior; this matters for the representative real-device path.
Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

Immediate include surface: `linux/kernel.h`, `linux/types.h`.
Detected declarations: `struct netxen_legacy_intr_set`.
Atlas domain: Driver Families / drivers/net.
Implementation status: source implementation candidate.
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.
