Hi, I'm using the full system config explained in this page: http://learning.gem5.org/book/part5/fs_config.html#running-a-full-system-simulation
I have modified the cache hierarchy to have a unified L2 cache. This config works as long as I use AtomicSimpleCPU or TimingSimpleCPU. When I switch to DerivO3CPU, it gives run time assertion error in the Packet::getPtr() method of mem/packet.hh file. I have added the error to the end of this mail. I have tried with gem5.debug and also with varing sizes for cache. However, the assertion is always failing. Any help would be appreciated. *Error*: Global frequency set at 1000000000000 ticks per second warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) info: kernel located at: /home/sethu/workspace/_x86/configs/full_system/binaries/x86_64-vmlinux-2.6.22.9 system.pc.com_1.device: Listening for connections on port 3456 0: rtc: Real-time clock set to Sun Jan 1 00:00:00 2012 0: system.remote_gdb: listening for remote gdb on port 7000 warn: Reading current count from inactive timer.
