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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `acpi/ghes.h`, `linux/edac.h`, `linux/dmi.h`, `edac_module.h`, `ras/ras_event.h`, `linux/notifier.h`, `linux/string.h`.
• Detected declarations: `struct ghes_pvt`, `struct memdev_dmi_entry`, `function mci_for_each_dimm`, `function dimm_setup_label`, `function assign_dmi_dimm_info`, `function enumerate_dimms`, `function ghes_scan_system`, `function print_mem_error_other_detail`, `function ghes_edac_report_mem_error`, `function ghes_edac_register`.
• Atlas domain: Driver Families / drivers/edac.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
