1) Correct
2) I believe the default is 2 seconds on the version for gem5. You can
always mount the image and browse/modify the bbench source.
3) By default the system runs with 1 cpu. -n 1 and not specifying -n are
the same.
4) No. You can modify the branch predictor by changing the params in

Hi,
I have some naive questions about the stats obtaining by running bbench.
1. stats.txt shows two sets of statistics. I presume one set is till boot
up and another is while running bbench. Is that right?
2. Bbench run on the desktop by default assumes 0 millisecond wait-time
before scrolling. Is
Hi Michael,
0. What are you looking when you say more documentation?
1. How long did you wait? The bbench simulation takes 8 hours to complete
for me when you dont specify the cpu type (default is AtomicSimple). Of
this, I suppose ~2 hours should be boot up. If the cpu is arm_detailed, it
takes a d
Thanks. I was able to build and run the simulation. I also was able to use
m5term to connect to the machine.
My question now is if there is any more documentation on running bbench on
Android? I have followed the steps from:
http://www.gem5.org/Bbench-gem5
Is there anyway to get a gui? Or is it
scons build/ARM/m5.fast should suffice. (I am on the older version, where
FS/SE was separate, dunno if the change has also changed the build
command).
I would recommend adding a "-j n" at the end of the command where n is the
number of cores you can spare for the build.

Tony,
What exactly should the scons command look like?
scons /path_to_gem5_root/build/ARM/m5.fast
?

Did you build GEM5 for ARM ?. Downloading M5 from the site alone is
not enough. Look at the instructions here :

Thank you for the quick response, but I still am having trouble finding this
ARM directory.
Here is what I have:
michael@ubuntu:~/Desktop/gem5-c739a3a829f5/build$ ls
gzstream scons_config.log variables
libelfsconsign.dblite variables.global

Oh, sorry. That is an artifact of the way the system used to be built. Now,
the binaries for FS/SE are combined into a single binary. So to run you
would do something like the follow:
./path_to_gem5_root/build/ARM/m5.fast configs/example/fs.py -b bbench
--kernel=/path_to_gem5_system/binaries/vmlin
Hi,
I am an engineering graduate student and I am currently trying to run an
android image using gem5. I am following these instructions:
http://www.m5sim.org/Bbench-gem5
However, I reach a snag when I get to this part:
Run /path_to_gem5_root/build/ARM_FS/m5.fast configs/example/fs.py -b bbench

Hi Zheng,
If you link your program with the m5 ops in util/m5 you
should be able to put
m5_dumpreset_stats(0,0);
__kernel();
m5_dumpreset_stats(0,0);
and that should accomplish what you want.

Hi Zheng,
You can insert "m5.stats.reset()" immediately before the __kernel()
function to restart the statistics and then call "m5.stats.dump()"
following the __kernel() function to see the effect.

Hi Tushar,
Thanks for the clarification. I had thought this earllier on, but when
reading the tutorial (slides 13-136) and gem5 wiki
(MOESI_CMP_directory), where there are references to multiple chips,
and simulationg SMP/SCMPs, I was trying to convince myself otherwise.

Hi,
I wonder how I can dump simulation statistics before and after calling a
function in the SE mode (ARM cpu).
For example, I want to collect simulation stats for executing the
__kernel() function in the following code:
int main()
{
..
__kernel();
…
}
Using m5.stats.dump() seems to only g
