Hello,
I am trying to create a linux kernel linux for Big Tsunami core with 64 cores.
I tried the steps suggested in the gem5 site for kernel creation. While
executing in OOO processor mode, it failed boot up with 32 cores. Please find
the output that i received on the console and m5term shell below:
