Maybe it is something very simple but we still don't
understand what means to profile misses. What is this
action doing?

We refer to the different events defined in the L2
such as L1_GETX and Fwd_GETX. We see that they can
come from an L1 or an L2. It's suposed that only local
L1 ask the L2 (L1_GETX) and other L1s need to go
through their L2 (Fwd_GETX) to get the block?
Because for Fwd_GETX it says "GetX from another
processor", does this mean another chip?

Thanks again for your help
