构建gem5和nvmain时的ModuleNotFoundError AbstractMemory

Question

在SEAL-UCSB/NVmain上执行完构建步骤后，当我运行

scons EXTRAS=../NVmain build/X86/gem5.opt

我得到以下错误。

ModuleNotFoundError: No module named 'AbstractMemory':
  File "/project/gem5/SConstruct", line 1243:
    SConscript('src/SConscript', variant_dir=variant_path,
  File "/usr/lib/scons/SCons/Script/SConscript.py", line 660:

  File "/usr/lib/scons/SCons/Script/SConscript.py", line 597:
    return _SConscript(self.fs, *files, **subst_kw)
  File "/usr/lib/scons/SCons/Script/SConscript.py", line 286:

  File "<string>", line 1:
    
  File "/project/hsieh123/gem5/build/X86/SConscript", line 763:
    exec(compiled, mod.__dict__)
  File "/project/hsieh123/NVmain/Simulators/gem5/NVMainMemory.py", line 34:
    from AbstractMemory import *

Answer 1

这是因为gem5版本更新了，nvmain与gem5的集成已经过时了。我的解决方案是在Ln: 34-35处替换NVmain/Simulators/gem5/NVMainMemory.py中的两行

从…

from AbstractMemory import *
from ClockDomain import *

至

from m5.objects.AbstractMemory import *
from m5.objects.ClockDomain import *
