Hi Giacomo ,
Thank you for your email
I am writing a brief description of my problem once again , I have done ARM
Full system simulation by passing a disk image with required packages and
benchmarks installed using qemu.I am trying use the script fs_power.py ,to
simulate or obtain power numbers while running my benchmarks on gem5 for
ARM architecture.
I am attaching the full log of m5 term below :

The command I passed is as follows :
./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/ubuntu-18.04-server-cloudimg-arm64.img
--caches
I have also tried this hack of changing this part of the code in
fs_bigLITTLE.py as fs_power.py uses it :
parser.add_argument(
"--root",
type=str,
default="/dev/vda1",
help="Specify the kernel CLI root= argument",
)
I changed default = "/dev/vda1" to /dev/vad2 and /dev/vda but none of this
helped and keeps causing the kernel panic error ,
Kindly let me know what needs to be done.
Thank you in advance
Regards
Saras
