Kamenee Arumugam 0719007663 IB/hfi1: Convert PortXmitWait/PortVLXmitWait counters to flit times ... HFI's counters SendWaitCnt and SendWaitVlCnt are in units of TXE cycle time (at 805MHz). OPA counters PortXmitWait and PortVLXmtWait are in units of flit times. Convert the counter values to flit units using following conversion formula: PortXmitWait = SendWaitCnt * 2 * (4 /link_width) * (25 Gbps /link_speed) PortVLXmitWait = SendWaitVLCnt * 2 * (4 /link_width) * (25 Gbps /link_speed) At link up or downgrade events, the link width can change. To ensure accurate counter calculations, sample the counters after the events, during counter requests, and then aggregate the OPA counters. Reviewed-by: Michael J.
