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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• 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.

• Immediate include surface: `asm/io.h`, `linux/blkdev.h`, `linux/module.h`, `scsi/scsi_host.h`, `linux/init.h`, `linux/ioport.h`, `linux/isa.h`, `linux/pnp.h`.
• Detected declarations: `function g_NCR5380_trigger_irq`, `function g_NCR5380_probe_irq`, `function magic_configure`, `function legacy_empty_irq_handler`, `function legacy_find_free_irq`, `function generic_NCR5380_init_one`, `function generic_NCR5380_release_resources`, `function wait_for_53c80_access`, `function generic_NCR5380_precv`, `function generic_NCR5380_psend`.
• Atlas domain: Driver Families / drivers/scsi.
• Implementation status: integration 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.
