I'm using SocWatch for analyzing the performance of a Wireless NIC. According to the PCIe LPM Report, the device spends its time in L0 (73%), L1(22%) and Retrain (5%). I'm trying to understand if the high Retrain part indicates a problem or maybe the L0/L1 transitions are being counted as retrain. I did not manage to find any documentation regarding the definition of the PCIe link state counters. Any help would be appreciated.
