Hi
I am totally new at linux and gem5. I
am using ubuntu 13.04 and I want to use gem5 x86 full system
simulation . In order to do that, I installed gem5 x86 with using
these commands.
hg clone http://repo.gem5.org/gem5
cd gem5
scons build/X86/gem5.opt (I could not
install gem5.fast it gives an error at checking part at very early like 3rd min
of installation)
Now I am able to see hello world with
using
~/Desktop/gem5$ build/X86/gem5.opt
configs/example/se.py -c tests/test-progs/hello/bin/x86/linux/hello
(I installed gem5 to my Desktop)
Then I created folder which name is
full_system_images and I downloaded 2 files under the
full-system-stuff on gem5 website. X86 Full System Files and config
files. I extracted them after that I put them under my
full_system_images folder.I also found that i need
big-swap2.img (i saw in forums) and I downloaded alpha Full System Files. I
extracted
it and I put the files in the my full_system_images folder. I did not
change the previous folders and files. I just copied files and copied
and pasted them near previous files according to their folder names.
(for example now I have
linux-bigswap2.img , linux-latest.img and linux-x86.img in the same
disks folder ---> /home/ali/Desktop/full_system_images/disks)
Then I run ~/Desktop/gem5$
build/X86/gem5.opt configs/example/fs.py
–disk-image=/home/ali/Desktop/full_system_images/disks/linux-x86.img

When I was looking the forums I saw
that people use kernel (I do not know why. I previously installed ARM
to my laptop and I was able to build it with simply using
build/ARM/gem5.opt
configs/example/fs.py
--disk-image=/home/ali/full_system_images/disks/arm-ubuntu-natty-headless.img
--mem-size=256MB --l2cache --l2_size=2MB)
I tried with kernel
ali@ali:~/Desktop/gem5$
build/X86/gem5.opt configs/example/fs.py
--disk-image=/home/ali/Desktop/full_system_images/disks/linux-x86.img
--kernel=/home/ali/Desktop/full_system_images/binaries/x86_64-vmlinux-2.6.22.9
(later I tried some solutions that I
found from mail lists which also includes changing the .img to
x86root.img but the result is same.)

What should i need to do build X86 and also why i cant build gem5.fast (and
also gem5.prof) with usingali@ali:~/Desktop/gem5$ cd
