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.
• 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: `linux/module.h`, `rtrs-srv.h`, `rtrs-log.h`, `rdma/ib_cm.h`, `rdma/ib_verbs.h`, `rtrs-srv-trace.h`.
• Detected declarations: `function rtrs_srv_change_state`, `function free_id`, `function rtrs_srv_free_ops_ids`, `function rtrs_srv_inflight_ref_release`, `function rtrs_srv_alloc_ops_ids`, `function rtrs_srv_get_ops_ids`, `function rtrs_srv_put_ops_ids`, `function rtrs_srv_reg_mr_done`, `function rdma_write_sg`, `function send_io_resp_imm`.
• 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.
• 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.
