I am doing a multicore simulation and I only want to measure cache misses
during the guest application's parallel phase
I added two systemcalls which tells m5 to start measure and stop messure, the
system calls will be called by the guest application when it reaches its
parallel phase.
I can get around it by using my own variables. But I LOVE m5 and I would
prefer to use its stats if possible.
It's a pity that the functionality is turned off. Is there a patch for it?
Thanks!
