基于GEM5全系统仿真的X86致命错误:无内核加载

Question

我需要为Gem5架构运行FS模式的X86。按照所有现有指示：

1. 我使用以下方法设置环境变量：

M5_PATH="/home/vikas/full_system_images/" >> ./.bashrc

1. 当我尝试运行Gem5时，如下所示：

./build/X86/gem5.opt configs/example/fs.py --disk-image=/home/mysys/full-system-images/disks/linux-x86.img

我知道错误：

warn: Enum already exists in allParams. This may be caused by the Python 2.7 compatibility layer.
warn: ScopedEnum already exists in allParams. This may be caused by the Python 2.7 compatibility layer.

我真的需要帮助才能找到解决这个问题的办法。

Answer 1

不再需要M5_PATH了，如：Gem 5 IOError:找不到系统文件的路径。全系统X86仿真装置只是使用--kernel显式地指向内核映像，这样就不太可能出错了。

如果它仍然不能工作，尝试调试一个但更远，或与这种完全自动化的设置只起作用不同。
