Everyone,
I am new to gem5 and I am having a problem getting x86 Full System to
finishing booting when running with smp turned on. I have replicated
this problem with the kernels provided on the gem5 download site and
with a kernel I built.
I am unsure how to proceed here since I am new. Any help on this
would be appreciated.
The command I am using is:
~/Downloads/gem5/gem5$ build/X86/gem5.opt configs/example/fs.py -n 2
--kernel=/home/jlclemon/Downloads/gem5/SystemFiles/x86-system/binaries/x86_64-vmlinux-2.6.28.4.smp
And the output from Gem5 is:
warning: add_child('terminal'): child 'terminal' already has parent
Global frequency set at 1000000000000 ticks per second
0: rtc: Real-time clock set to Sun Jan 1 00:00:00 2012
