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/cleanup.h`, `linux/delay.h`, `linux/device.h`, `linux/errno.h`, `linux/init.h`, `linux/interrupt.h`, `linux/io.h`, `linux/iopoll.h`.
• Detected declarations: `struct intel_scu_ipc_dev`, `struct intel_scu_ipc_devres`, `function intel_scu_ipc_dev_get`, `function intel_scu_ipc_dev_put`, `function devm_intel_scu_ipc_dev_release`, `function devm_intel_scu_ipc_dev_get`, `function Register`, `function Buffer`, `function Register`, `function ipc_data_readl`.
• Atlas domain: Driver Families / drivers/platform.
• 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.
