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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• 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.

• Immediate include surface: `linux/delay.h`, `linux/interrupt.h`, `linux/init.h`, `linux/pci.h`, `linux/slab.h`, `linux/module.h`, `linux/mutex.h`, `sound/core.h`.
• Detected declarations: `struct vt1724_pcm_reg`, `function stdclock_is_spdif_master`, `function is_pro_rate_locked`, `function snd_vt1724_ac97_ready`, `function snd_vt1724_ac97_wait_bit`, `function snd_vt1724_ac97_write`, `function snd_vt1724_ac97_read`, `function snd_vt1724_set_gpio_dir`, `function snd_vt1724_get_gpio_dir`, `function snd_vt1724_set_gpio_mask`.
• Atlas domain: Driver Families / sound/pci.
• Implementation status: pattern implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
• 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.
