This alternative is relevant to MIG GPU and compute instance partition profiles but does not directly resolve the current DOCA and BlueField host driver interoperability issue: Choose supported MIG GPU-instance profiles and create matching compute instances with validated resource assignments. Observed scenario: A system uses a DOCA user-space library newer than the supported BlueField firmware while sample applications fail. The governing mechanism is: BlueField-based services depend on a compatible host and embedded software stack; NIC link state alone is inadequate.
