Good to know. Then I suppose the correct accounting is:
<stat name="total_cycles" value="{{ core.numCycles }}"/>
<stat name="idle_cycles" value="{{ core.idleCycles }}"/>
<stat name="busy_cycles" value="{{ core.numCycles - core.idleCycles }}"/>
If so, I'll commit a fix for that. I started writing this code using a very old
gem5 version, thus the "oldstable" templates.
BTW, are there any plans for dumping stats in JSON format? That would greatly
simplify post-processing of results, and its very simple to write a script that
dumps JSON stats in the current text format. Another issue I've found is that
conditional stats dumping complicates post-processing (e.g., some stats are not
dumped if their value is zero).
Thanks,
Lluis
