Re: [gem5-users] gem5 X86 Full System fails with DerivO3CPU
Abhishek, I’ve submitted a change (merged today) which should fix the issue you reported. However, you may still have some issues booting the kernel with the O3 CPU depending on the kernel (compilation configs) and boot process you choose. I suggest using the kvm cpu for bootup, take a checkpoint right after the boot, and then restore using the CPU model you want to use (O3 I assume).

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. I want to run some benchmarks which require FS mode of x86, so I developed new image and kernel and it works correctly for AtomicSimpleCPU and TimingSimpleCPU. I also used gdb tool with O3CPU to see wh
