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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/dmi.h`, `linux/kernel.h`, `linux/module.h`, `linux/platform_data/x86/simatic-ipc.h`, `linux/platform_device.h`.
• Detected declarations: `function register_platform_devices`, `function request_additional_modules`, `function simatic_ipc_init_module`, `function simatic_ipc_exit_module`, `module init simatic_ipc_init_module`.
• Atlas domain: Driver Families / drivers/platform.
• Implementation status: integration 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.
