Hi Stephen,
Thanks for the reply. I have put my own debugging statements in the
components/Common/TraceTracker.cpp file. However, it seems that I need to
enable the trace-tracking option in order to get the extra information. The
components/TraceTrackerComponent.hpp has a parameter called "enable" which
is set to 'false' by default. How can I enable this option? Should I include
the command { flexus.set "trace-tracker:enable" "true" } in the
config/flexpoint/start.simics ?
Also, in general where can I get the complete list of component names and
corresponding parameters which can be used for the 'flexus.set' statements.
Currently, I am just looking at the *.hpp files in the components directory,
but I am unsure of the names of the components to use.
regards,
Abhishek

Dear Abhishek,
Probably the easiest way to accomplish this in Flexus is through the
TraceTracker. Each cache makes a call into TraceTracker on every access,
which should provide the information you require. The default
TraceTracker functions perform no actions, but it is simple to add
whatever code you need (components/Common/TraceTracker.cpp). To get the
current cycle, call "theFlexus->cycleCount()".
Cheers,
Stephen
