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.
• Defines an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• 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/cleanup.h`, `linux/device.h`, `linux/dma-mapping.h`, `linux/err.h`, `linux/errno.h`, `linux/interrupt.h`, `linux/module.h`, `linux/mutex.h`.
• Detected declarations: `function Copyright`, `function mei_csc_probe`, `function mei_csc_shutdown`, `function mei_csc_remove`, `function mei_csc_pci_prepare`, `function mei_csc_pci_suspend`, `function mei_csc_pci_resume`, `function mei_csc_pci_complete`, `function mei_csc_pm_runtime_idle`, `function mei_csc_pm_runtime_suspend`.
• Atlas domain: Driver Families / drivers/misc.
• Implementation status: pattern 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.
