Oscillator vary in frequency. In order to accurately convert to NS the drift due to temperature etc needs to be taken into consideration. The "ns" value there is pretty rough as well. Accurate time may need time software to continually monitor the *actual* frequency of the oscillator. I thknk the raw cycles and the rought oscillator speed are fine. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
