doca-verbs

separate

Raw verbs inside DOCA Core (doca-verbs): direct control of QP, CQ, PD, SRQ and address-handle objects through doca_verbs_context and doca_verbs_qp_create / doca_verbs_qp_modify / doca_verbs_cq_create, porting libibverbs code into DOCA Core, or a QP attribute, opcode or WR flag the doca-rdma task API does not expose. Trigger on "raw QP attribute the task API does not expose", "porting libibverbs code", "IO_FAILED on WR submit", "QP state transition rejected", or "attach a congestion-control group", even without naming doca-verbs. Refuse and route elsewhere for ordinary doca-rdma / doca-eth / doca-rmax workloads, DOCA install, Core internals, and general libibverbs theory.

When to use

• raw QP attribute the task API does not expose
• porting libibverbs code
• IO_FAILED on WR submit
• QP state transition rejected
• attach a congestion-control group
• custom CQ handling beyond the progress engine
• explicit SRQ control
• Address-Handle tuning

When not to use

• ordinary doca-rdma workloads
• doca-eth workloads
• doca-rmax workloads
• DOCA install
• Core internals
• general libibverbs theory
• general RDMA data movement
