答案 0 :(得分：0)
您是否使用m5 exit call或相应的m5op exit instruction正确退出了模拟？
默认情况下，由于以下这一行，gem5在正确退出时会转储统计信息：https://github.com/gem5/gem5/blob/7a6183aa6162419912daa5647d13f030ab0904e2/src/python/m5/simulate.py#L165原因：https://www.mail-archive.com/gem5-dev@gem5.org/msg27603.html
或者，您也可以使用m5 dumpstats调用或相应的m5op显式转储统计信息：这是最常见的用例（与m5 resetstats一起使用），因为它使您可以更好地控制哪些统计信息将被丢弃。
