Hi,
Thanks Ali. I am using a patched kernel now with the modifications
you suggested. Running specweb in FS mode. What I want to do is
differentiate memory access of the m5-spec thread from all others (like OS
ones). I get the following output:
***

--------
So, if the OS thread swapper began at tick "487306156500", and the m5-spec
begins at "487306811000" does it mean than all the memory accesses between
these time points are that of "swapper"?. And all accesses after
487306811000 are of m5-spec, till a new thread is executed? Or am I wrong
here? If this is right, all I will have to do is right a script which parses
this output inline and picks accesses which start when "m5-spec" is started
and end at the next thread execution.
Thanks,
Sujay
