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/delay.h
• linux/module.h
• linux/pci.h
• linux/slab.h
• sound/core.h
• sound/sb.h
• sound/initval.h

Detected Declarations

• struct snd_cs5530
• function snd_cs5530_mixer_read
• function snd_cs5530_create
• function snd_cs5530_probe

Annotated Snippet

static struct pci_driver cs5530_driver = {
	.name = KBUILD_MODNAME,
	.id_table = snd_cs5530_ids,
	.probe = snd_cs5530_probe,
};

module_pci_driver(cs5530_driver);

Annotation

• Immediate include surface: `linux/delay.h`, `linux/module.h`, `linux/pci.h`, `linux/slab.h`, `sound/core.h`, `sound/sb.h`, `sound/initval.h`.
• Detected declarations: `struct snd_cs5530`, `function snd_cs5530_mixer_read`, `function snd_cs5530_create`, `function snd_cs5530_probe`.
• Atlas domain: Driver Families / sound/pci.
• 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.
