Why This File Exists

Part of the selected hardware vertical slice: PCI discovery, driver binding, NVMe queues, block requests, DMA, interrupts, and completion.

• Part of the selected hardware vertical slice: PCI discovery, driver binding, NVMe queues, block requests, DMA, interrupts, and completion.
• 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
• linux/pci.h

Detected Declarations

• function pci_pf_stub_probe

Annotated Snippet

	.name			= "pci-pf-stub",
	.id_table		= pci_pf_stub_whitelist,
	.probe			= pci_pf_stub_probe,
	.sriov_configure	= pci_sriov_configure_simple,
};

Annotation

• Immediate include surface: `linux/module.h`, `linux/pci.h`.
• Detected declarations: `function pci_pf_stub_probe`.
• Atlas domain: Representative Device Path / PCIe NVMe Storage Path.
• 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.
