Does anyone have experience compiling/running any of the MiBench
programs on the ARM simulator? I tried cross-compiling the qsort
example, but it seg faults. I'm not sure if I'm missing a param to gcc
or what... I am compiling with:
arm-none-linux-gnueabi-gcc -static qsort_small.c -O3 -o qsort_sma

Is there a reason the following stats are not reset after dumpresetstats ?
* final_tick
* host_inst_rate
* host_op_rate
* sim_inst
* sim_ops

Since I can't see the terminal output, my assumption is that everything is
running fine. The warnings and such are all expected/known. On my setup, using
the Bbench images for Android Gingerbread and ICS, gem5.opt boots in about 30
minutes - 1 hour, your mileage may vary. You aren't running a be
At the beginning of my sim, I run m5 dumpresetstats, then every so
often I call m5 dumpresetstatus again. The first call produces:

system.realview.nvmem.bw_inst_read 2

I've completed a few benchmark runs, and in looking at the stats I'm a
little confused. Specifically regarding the translation buffers... The
dtb is the "data", and the "itb" is the instruction, correct? Why then
do the comments on many of the "itb" lines says "DTB"? Is this a
copy/past mistake or
this on the list once I have an image with BBench on it.

I am trying to create and port some benchmarks over to gem5 Android.
I've been basing my efforts on BBench, but I have a few questions
about its implementation.
In init.rc, "m5 readfile" is called to read "start_apk.sh". This is
actually the benchmark script (.rcS) that is passed in from
Benchmark

.
The end goal is to use the same kernel/disk images on qemu and gem5,
and use qemu to "fastforward" gem5.

I am attempting to duplicate the android kernel provided with gem5.
Following the instructions here:
http://www.linux-arm.org/LinuxKernel/LinuxAndroidPlatform
I cloned the repo: git clone git://linux-arm.org/linux-2.6-armdroid.git
and checkout'd 2.6.38-armdroid with: git checkout -b 2.6.38-armdr

I'm wondering if anyone has built a kernel/disk image for ICS? The
site documentation is missing the steps to building a kernel and disk
image, but if anyone has tried or knows of reasons why it won't work,
please share.

I ran the BBench benchmark as described online for about 8 hours. The
only output I got was "Warn xyz instruction not implemented", is this
normal? How long does this benchmark take to run? I know it is
dependent on the host machine, but I'm just looking for a ball-park?
Is 8 hours enough, did I do
There are some provided images for Android and BBench using
Gingerbread. Does anyone have any later/newer images, or can anyone
direct me on how to build my own images?

I am trying to get gem5 up and running on Mac OSX 10.6.8. I'm reasonably
certain I have the required materials. I've installed the scons-local
package within the gem5 directory. The following output is from my
attempt to build. I'm unfamiliar with the system, so any help would be
