您是否使用m5 exit调用或相应的 m5op 退出指令正确退出模拟？
默认情况下，gem5 在正确退出时会转储统计信息，原因如下： 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 来显式转储统计信息：这是最常见的用例(与m5 resetstats一起(，因为它可以让您更好地控制要转储的统计信息。
