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.

Dependency Surface

• linux/pci.h
• video/nomodeset.h
• loongson_module.h

Detected Declarations

• function loongson_module_init
• function loongson_module_exit
• module init loongson_module_init

Annotated Snippet

module_init(loongson_module_init);

static void __exit loongson_module_exit(void)
{
	pci_unregister_driver(&lsdc_pci_driver);
}
module_exit(loongson_module_exit);

Annotation

• Immediate include surface: `linux/pci.h`, `video/nomodeset.h`, `loongson_module.h`.
• Detected declarations: `function loongson_module_init`, `function loongson_module_exit`, `module init loongson_module_init`.
• Atlas domain: Driver Families / drivers/gpu.
• Implementation status: integration 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.
