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.

Annotation

• Immediate include surface: `linux/module.h`, `linux/kernel.h`, `linux/string.h`, `linux/signal.h`, `linux/errno.h`, `linux/proc_fs.h`, `linux/ioport.h`, `linux/blkdev.h`.
• Detected declarations: `enum res_abort`, `function cating`, `function sbic_arm_write`, `function sbic_arm_read`, `function dmac_address`, `function acornscsi_dumpdma`, `function acornscsi_sbic_xfcount`, `function acornscsi_sbic_wait`, `function acornscsi_sbic_issuecmd`, `function acornscsi_csdelay`.
• 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.
