Hi all:
I have a problem with the python script. I want to add an L1cache and an
L2cache to the O3CPU using the python script fs_l2cache.py. The M5 edition
is 2.0.1. My operation system is FC6. The fs_l2cache.py is as follows(I
just changed a little from the fs.py ):

However, I get the following error message:

Could somebody tell me what is wrong with my configure script? How can I
change it? Thank you very much.
