I am trying to simulate ffmpeg with fs mode. I downloaded x86 image and
binaries, set the paths towards them ( this fixed can't find system path
problem ).
I followed tutorial:
/work/gem5] mount –o loop,offset=32256 linux-x86.img /mnt
[/work/gem5] ls /mnt
bin boot dev etc home lib lost+found media mnt proc root sbin
sys tmp usr var writable
[/work/gem5] cp queens /mnt
[/work/gem5] cp queens-w-chkpt /mnt // this step didn't work but I am
guessing that this is important only for use of checkpoints.
Now, I need a help with the script. My ffmpeg is in gem5 root, so how to
create that script, what exactly that script does?
After that my simulation command should be ./build/X86/gem5.opt
./configs/example/fs.py --script=./ffmpeg.rcS // also I would like to
pass AVIDemo.avi as an argument so should I specify that in the script?
I tried different one and got this:
command line: ./build/X86/gem5.opt configs/example/fs.py
--script=./configs/boot/queens.rcS
