Bug 1

$ import m5
error: import-im6.q16: attempt to perform an operation not allowed by the security policy `PS' @ error/constitute.c/IsCoderAuthorized/408.

Solution

sudo vi /etc/ImageMagick-6/policy.xml

change the rights='none' to rights='read|write' in the lines below:

 <!-- <policy domain="module" rights="read|write" pattern="{PS,PDF,XPS}" /> -->

  <policy domain="coder" rights="read|write" pattern="PS" />
  <policy domain="coder" rights="none" pattern="PS2" />
  <policy domain="coder" rights="none" pattern="PS3" />
  <policy domain="coder" rights="none" pattern="EPS" />
  <policy domain="coder" rights="none" pattern="PDF" />
  <policy domain="coder" rights="none" pattern="XPS" />

Bug 2

when running the example scripts two_level.py, error occurs:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "build/X86/python/m5/main.py", line 457, in main
    exec(filecode, scope)
  File "configs/tutorial/two_level.py", line 53, in <module>
    from caches import *
  File "configs/tutorial/caches.py", line 44, in <module>
    from common import SimpleOpts
ModuleNotFoundError: No module named 'common'

then I opened the two_level.py, modified the following sentence:

m5.util.addToPath('../../')  -->  m5.util.addToPath('../')

I deleted one of the '../', this sentence means to add the common scripts(under gem5/configs/) to our path. 

there is only one '../' switch from gem5/configs/tutorials/ to gem5/configs/

Bug 3

panic: panic condition fd < 0 occurred: Failed to open file /home/zhengyi/gem5_X86/configs/tutorial/../../../tests/test-progs/hello/bin/x86/linux/hell

same as above, one of the '../' in two_level.py should be deleted:

binary = os.path.join(thispath, '../../../',
                      'tests/test-progs/hello/bin/', isa, 'linux/hello')
