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.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `smipcie.h`, `m88ds3103.h`, `ts2020.h`, `m88rs6000t.h`, `si2168.h`, `si2157.h`.
• Detected declarations: `function smi_hw_init`, `function smi_i2c_cfg`, `function smi_i2c_setsda`, `function smi_i2c_setscl`, `function smi_i2c_getsda`, `function smi_i2c_getscl`, `function smi_i2c0_setsda`, `function smi_i2c0_setscl`, `function smi_i2c0_getsda`, `function smi_i2c0_getscl`.
• Atlas domain: Driver Families / drivers/media.
• Implementation status: pattern 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.
