The .py files that are outside configs are compiled into the gem5 binary, so if you change any of them you have to re-run scons to see the effect.
At one time we had an environment variable that you could set that would force gem5 to ignore the compiled-in python files and use the ones in the filesystem instead, which is handy for when you're debugging/developing in the python code, but I can't find it now... I vaguely recall that that feature may have been removed in some rewrite. (Nate?) You can also pass --pdb to gem5 to fire up pdb before any config files are processed. You can probably set breakpoints from the command line at that point, though it's unclear to me what file path you would need to use for pdb to find the right files. I updated the wiki with some of this information; please add more if you have other suggestions or find out further details: http://gem5.org/Debugging#Debugging_Python_with_PDB Steve On Sat, Mar 24, 2012 at 2:13 PM, Tony Feng <[email protected]> wrote: > Hi, > > I find PDB very handy when debugging configuration files.
