thanks,
But, it does not work.

I have tried "ext2 " , the same thing.

I set up loopdevice

/home/normal/m5_2.0b4/dist/m5/system/disks/linux-latest.img
And then, I
mke2fs -c /dev/loop2 1000
And then,
[root@ m5_2.0b4]# mount -t ext2 /dev/loop2
/home/normal/m5_2.0b4/m5root2
but, when I go to /home/normal/m5_2.0b4/m5root2.
[EMAIL PROTECTED] ls -l

Only, this directory.
I can not see the linux-latest.img .

linux-latest.img is the root image. if you mount it, you will see the
directories as you saw them when running m5.

I installed "M5 2.0b3 Full System Files" in m5/dist/m5/system.
In the directory , I have

And, I should mount linux-bigswap2.img or linux-latest.img ?
and where to mount them ?
I do not have root directory in m5.

Hi,
I am using m5.opt and m5.debug to run FS simulation.
./build/ALPHA_FS/m5.opt configs/example/fs.py -b NetperfMaerts
build/ALPHA_FS/m5.debug -d /tmp/output configs/example/fs.py
build/ALPHA_FS/m5.opt --trace-flags="Cache" configs/example/fs.py
And, I connect to the simulated console interface by
m5term localhost 3456
But, the console responds my typing very slowly.
And, I use ls and got :
benchmarks etc lib mnt sbin usr
bin floppy lost+found modules sys var
dev home man proc tmp z
My question is :
Where are these directories located ?
In the root directory of the disk image you've mounted in m5.
And, where is the linux kernel located ?
That's loaded separately; it's not on the disk image.
If I want to implement a linux scheduling algorithm in a linux kernel.
And, I plan to use linux-dist to Create Disk Images and Kernels for M5
with compiled benchmarks.
And then, I install the disk in the directory:
/dist/m5/system
And, when I run the benchmarks .
How can I make sure that the threads generated from the benchmarks
are scheduled by th new linux kernel ?
It's pretty much the same as if you were doing it on a real system... if you
want to be sure it's working, you just have to observe that it's having some
effect.

thanks,
