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.
- 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/module.h`, `linux/init.h`, `linux/parport.h`, `linux/interrupt.h`, `asm/setup.h`, `asm/atarihw.h`, `asm/irq.h`, `asm/atariints.h`.
- Detected declarations: `function parport_atari_read_data`, `function parport_atari_write_data`, `function parport_atari_read_control`, `function parport_atari_write_control`, `function parport_atari_frob_control`, `function parport_atari_read_status`, `function parport_atari_init_state`, `function parport_atari_disable_irq`, `function parport_atari_data_forward`, `function parport_atari_data_reverse`.
- Atlas domain: Driver Families / drivers/parport.
- Implementation status: integration 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.
