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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

• Immediate include surface: `linux/module.h`, `linux/printk.h`, `linux/pci.h`, `linux/irq.h`, `net/addrconf.h`, `rdma/ib_addr.h`, `rdma/ib_mad.h`, `ionic_ibdev.h`.
• Detected declarations: `function ionic_query_device`, `function ionic_query_port`, `function ionic_get_link_layer`, `function ionic_query_pkey`, `function ionic_modify_device`, `function ionic_get_port_immutable`, `function ionic_get_dev_fw_str`, `function hw_rev_show`, `function hca_type_show`, `function ionic_disassociate_ucontext`.
• Atlas domain: Driver Families / drivers/infiniband.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
