Hello Everyone, I am trying to run the gem5 full system with X86 ISA and DerivO3CPU
I have built image and kernel following Jason's Website (ref: http://www.lowepower.com/jason/setting-up-gem5-full-system.html) My image is* Ubuntu 16.04.5 LTS* My kernel is *Linux-4.8.13* Gem5 version: Latest as of 6th March 2019 The image and kernel work fine with Atomic and Timing CPU for x86. But for O3CPU, it gives an error as shown below: """"""""" command line: *./build/X86/gem5.opt configs/example/fs.py --script=./script.rcS --disk-image=/home/abs218/image_kernel/ubuntu-test.img --kernel=/home/abs218/new_fs/gem5/linux-4.8.13/vmlinux --caches --l2cache --cpu-type=DerivO3CPU* 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/abs218/new_fs/gem5/linux-4.8.13/vmlinux 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. **** REAL SIMULATION **** info: Entering event queue @ 0.

I can run parsec v2.1 using their image " http://www.cs.utexas.edu/~cart/parsec_m5/"; and gem5's old kernel using x86 03CPU and Fast forwarding.

to this problem. Also, I think its high time we have to share a startup latest image(Ubuntu) and kernel for x86. Best regards, Abhishek
