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

Dependency Surface

• linux/module.h
• ocxl_internal.h

Detected Declarations

• function ocxl_probe
• function list_for_each_entry_safe
• function ocxl_remove
• function list_for_each_entry

Annotated Snippet

struct pci_driver ocxl_pci_driver = {
	.name = "ocxl",
	.id_table = ocxl_pci_tbl,
	.probe = ocxl_probe,
	.remove = ocxl_remove,
	.shutdown = ocxl_remove,
};

Annotation

• Immediate include surface: `linux/module.h`, `ocxl_internal.h`.
• Detected declarations: `function ocxl_probe`, `function list_for_each_entry_safe`, `function ocxl_remove`, `function list_for_each_entry`.
• Atlas domain: Driver Families / drivers/misc.
• Implementation status: pattern 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.
