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.

Annotation

• Immediate include surface: `linux/kernel.h`, `linux/module.h`, `linux/platform_device.h`, `linux/pci.h`, `mt7615.h`, `regs.h`, `mac.h`, `../trace.h`.
• Detected declarations: `function mt7615_rx_poll_complete`, `function mt7615_irq_handler`, `function mt7615_irq_tasklet`, `function __mt7615_reg_addr`, `function mt7615_rr`, `function mt7615_wr`, `function mt7615_rmw`, `function mt7615_mmio_probe`, `function mt7615_init`, `function mt7615_exit`.
• Atlas domain: Driver Families / drivers/net.
• 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.
