Module manager_actor 

Ibverbs Manager

Contains ibverbs-specific RDMA logic.

Manages ibverbs resources including:

• Memory registration (CPU and CUDA via dmabuf or segment scanning)
• Queue pair creation and connection establishment
• RDMA domain and protection domain management
• Device selection and PCI-to-RDMA device mapping

Structs

IbvBackend

Wrapper around ActorHandle<IbvManagerActor<I>> that moves the RDMA data-plane (post send/recv, poll CQ) off the actor loop while keeping state-mutating operations (MR registration/deregistration, QP management) serialized through actor messages.

IbvManagerActor

Manages all ibverbs-specific RDMA resources and operations.

IbvRemoteBackendContext

Serializable per-buffer context for an ibverbs backend: the manager to route ops through and the wire description of the registered MR.

RawQueuePair

Local-only message: create a fresh, unconnected legacy legacy::IbvQueuePair on self_device and return it. The caller drives the connection itself — exchange IbvQpInfo with the other endpoint’s QP and call connect on each side. Lets doorbell tests and the cuda_ping_pong example poke a real QP without going through [QueuePairActor]; both want the legacy queue pair for its direct device-doorbell data path, independent of the backend’s production [IbvDomainImpl::QueuePair].
