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.

Annotated Snippet

	.name       = "ath9k",
	.id_table   = ath_pci_id_table,
	.probe      = ath_pci_probe,
	.remove     = ath_pci_remove,
	.driver.pm  = ATH9K_PM_OPS,
};

int ath_pci_init(void)
{
	return pci_register_driver(&ath_pci_driver);
}

void ath_pci_exit(void)
{
	pci_unregister_driver(&ath_pci_driver);
}

Annotation

• Immediate include surface: `linux/nl80211.h`, `linux/pci.h`, `linux/module.h`, `ath9k.h`.
• Detected declarations: `function ath_pci_read_cachesize`, `function ath_pci_eeprom_read`, `function ath_pci_aspm_init`, `function ath_pci_probe`, `function ath_pci_remove`, `function ath_pci_suspend`, `function ath_pci_resume`, `function ath_pci_init`, `function ath_pci_exit`.
• Atlas domain: Driver Families / drivers/net.
• 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.
