Hello Everyone,
I am doing a Full System simulation on ARM , I edited my image on qemu and
installed all necessary files
After that, I started the Gem5 FS using the following command,
./build/ARM/gem5.opt configs/example/arm/fs_power.py
--kernel=/home/saras/gem5-resources/src/arm-ubuntu/gem5/full_system_images/binaries/vmlinux.arm64
--disk=/home/saras/gem5-resources/src/arm-ubuntu/gem5/full_system_images/disks/arm64-ubuntu-server.img
--caches
The image gets booted up but takes a very long time to complete the process
and I haven't reached the login part yet, but the whole thing takes about
7-8 hours to run halfway through.
The m5term output is as follows.

I have also checked the size of my image using the command qemu-img info
arm64-ubuntu-server.img
image: arm64-ubuntu-server.img
file format: raw
virtual size: 142 GiB (152685248512 bytes)
disk size: 12.4 GiB
Is this difficulty due to the size of the image ?
Kindly let me know the reason
Thank you in advance
