Hi,
Really Great Thanks for this support.
Before trying these steps,i have a question about step No.8
This step can be done also through modifying the file "Syspaths.py"
except KeyError:
path = [ '/dist/m5/system',
'/home/wael/gem5/linux-2.6..28.4' ]
instead of
except KeyError:
path = [ '/dist/m5/system', '/n/poolfs/z/dist/m5/system' ]
So is this right or wrong ?
Thanks again
Best Regards
Wael AMR
