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: `saa7134.h`, `saa7134-reg.h`, `linux/init.h`, `linux/list.h`, `linux/module.h`, `linux/kernel.h`, `linux/delay.h`, `linux/kthread.h`.
• Detected declarations: `function pinnacle_antenna_pwr`, `function mt352_pinnacle_init`, `function mt352_aver777_init`, `function mt352_avermedia_xc3028_init`, `function mt352_pinnacle_tuner_set_params`, `function kworld_sbtvd_gate_ctrl`, `function philips_tda1004x_request_firmware`, `function philips_tda6651_pll_set`, `function philips_tu1216_init`, `function philips_td1316_tuner_init`.
• Atlas domain: Driver Families / drivers/media.
• 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.
