Thanks Byong Wu and Greg.
 
I don't have muh experience with GEMS,
so I was wondering how hard it would be to add more cache layers beyond L2.
It's good to hear that it is manageable. :)
Thanks.

You'll have to implement these using SLICC.  It's not trivial, as you
say, but it shouldn't be too hard to do what you're suggesting.  There
are plenty of examples to start from.
