- hierarchical state model which comprises of top level states and sub states - top level states include OPEN, CLOSE, ERROR, INPUT_STREAMING, OUTPUT_STREAMING, STREAMING. - sub states include DRAIN, DRC, DRAIN_LAST_BUFFER, DRC_LAST_BUFFER, INPUT_PAUSE, OUTPUT_PAUSE. - follows deterministic approach for key sequences like DRC, DRAIN and last flag handling i.e none of these events are ignored or discarded. - removal of auto start of firmware input port as part of ipsc handling. - introduction of hfi commands for host controlled PAUSE and RESUME of firmware ports. - introduction of information last flag packets for DRC and DRAIN when FW has insufficient output buffers.
