Hi Tushar,
I am currently building gem5 binary with MOESI_hammer. I will try to invoke
garnet with that binary as you suggested after it is done. As per the
patch, can I subscribe to the gem5-dev list to receive the emails regarding
it or do those emails appear on gem5-users list too?
Thanks,
Pavan
