Hi Sahar,
If I remember correctly, booting the aarch64 ubuntu image you are using in
atomic takes around 10-12 min. Until we have got KVM working for aarch64 I’m
afraid that is as fast as it will go. Rather than interacting with the
simulation, try and script what you want to do, boot, take a checkpoint, and
the iterate around what ever region of interest it is you want to capture. If
you’re not using KVM, then interacting directly with the simulator can be
rather painful.

Subject: [gem5-users] Full simulation take a long time
Hi all,
when I use this command for full simulation
./build/ARM/gem5.opt configs/example/fs.py --kernel=vmlinux.aarch64.20140821
--disk-image=/home/sahar/gem5/full_system_images/arch1/disks/aarch64-ubuntu-trusty-headless.img
--mem-size=512MB
after sahar@ubuntu:~/gem5$ m5term localhost 3456 in a new terminal , it does
not proceed any more and it remains in:
sahar@ubuntu:~/gem5$ ./build/ARM/gem5.opt configs/example/fs.py
--kernel=vmlinux.aarch64.20140821
--disk-image=/home/sahar/gem5/full_system_images/arch1/disks/aarch64-ubuntu-trusty-headless.img

Does anybody have suggestion about this problem?
Thank you,
