我在较新版本的香山上未能复现这个问题。香山近期在解决大量缺陷，您这个版本的香山有些旧了，您可以更新一下香山和ready-to-run的版本再尝试。

I have tried an new version of XianShan and the bug didn't occur. XiangShan team are solving a lot of bugs thesedays and the version of XiangShan you used is too old. You could try again after updating XiangShan and ready-to-run.

我执行了source update-submodule.sh仍然不行，香山怎样更新呢？需要重新git环境吗？

在 xs-env 里执行 source update-submodule.sh 应该能更新香山和各个子模块。在更新香山之后，需要重新编译香山。

麻烦您提供一下：

  • 更新后香山、ready-to-run 的 commit id
  • 您编译所用的命令

这个很难判断。我不太清楚您使用的机器是什么配置，但这个可能在较低配置的机器上可能确实需要很长时间。

ready-to-run 的 linux 大约需要运行 6,000,000 个周期。您可先运行 ready-to-run 下的 microbench 或 coremark，根据它们的周期数（microbench 约 234,000 个周期，coremark 约 300,000 个周期）和实际运行时间来大致估算您运行 linux 所需的时间。

作为参考，在 AMD EPYC 9684X 96-Core Processor 上使用 16 线程的 emu，运行 ready-to-run 里的 linux 大约需要半个小时的时间。更低的 CPU 性能、更少的线程数、虚拟机带来的性能损失都有可能让运行时间变得很长。

同祝您国庆节快乐。
