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.
• Defines an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/module.h
• linux/interrupt.h
• linux/comedi/comedi_pci.h
• amplc_dio200.h

Detected Declarations

• enum dio200_pci_model
• function dio200_pcie_board_setup
• function dio200_pci_auto_attach
• function dio200_pci_probe

Annotation

• Immediate include surface: `linux/module.h`, `linux/interrupt.h`, `linux/comedi/comedi_pci.h`, `amplc_dio200.h`.
• Detected declarations: `enum dio200_pci_model`, `function dio200_pcie_board_setup`, `function dio200_pci_auto_attach`, `function dio200_pci_probe`.
• Atlas domain: Driver Families / drivers/comedi.
• Implementation status: pattern 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.
