Respected,
Steve,
I am using the simple commands described on the gem5 website with the linux
kernel also downloaded from gem5 website. I am doing it for ARM.
build/ARM/gem5.opt configs/example/fs.py --disk-image=/home/junaid/
gem5/disks/arm-ubuntu-natty-headless.img
Is there any detailed CPU model in this?
Ruslan,
Are you also building the system for ARM?

Hi,
I was trying to find out boot time of different gem5 (opt, fast) build
options. The gem5.opt boots in 90 minuts on my dual core machine. while
gem5.fast takes 60 minutes. Why is this time so long as compared to other
emulators such as Qemu. Qemu boots in 40 seconds on my system.

gem5 is a simulator, not an emulator. Nevertheless, those times seem very
long, unless you are using the detailed CPU model or something.
