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.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/cdrom.h`, `linux/highmem.h`, `linux/module.h`, `linux/slab.h`, `scsi/scsi.h`, `scsi/scsi_cmnd.h`, `scsi/scsi_dbg.h`, `scsi/scsi_device.h`.
• Detected declarations: `struct ps3rom_private`, `struct lv1_atapi_cmnd_block`, `enum lv1_atapi_proto`, `enum lv1_atapi_in_out`, `function ps3rom_sdev_configure`, `function ps3rom_atapi_request`, `function srb10_lba`, `function srb10_len`, `function ps3rom_read_request`, `function ps3rom_write_request`.
• 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.
