How to extract files from images can be found easily by Googling.
But I would instead recommend that you actually build/install the app
yourself to know what you are actually getting. And in that case, yes,
QEMU is possibly your best option in that case, as it can alter the disk
image.

Thanks Ciro for your email. I can build new image and new kernel but the
problem is how to get the benchmarks from the old image? Is there anyway
to get the image working on qemu to take copy of the benchmarks ? Best

I'm afraid I don't have a super automated setup that just works for
Android, and haven't done this myself specifically, but here are some
thoughts:
- those instructions are like large part of the wiki old and may have
stopped working --machine-type=VExpress_EMM is not recommended anymore,
the default and recommended and often tested platform is VExpress_GEM5_V1
- try one of the newer kernels
- is it really representative to run experiments on 32-bit arm now that
all Android phones are 64-bit?

*Subject:* [gem5-users] Asim benchmarks on gem5
I have followed the instructions provided in the gem5.org website to run
the Moby benchmarks on gem5 as follows:
1. Downloaded the Asimbench from
https://bitbucket.org/yongbing_huang/asimbench/downloads/ which contains
the following folders and files:
1. asimbench_android_arm_kernel :
vmlinux.smp.ics.arm.asimbench.2.6.35
2. asimbench_boot_scripts : contains the rcs scripts for
different benchmarks
3. asimbench_disk_image :
ARMv7a-ICS-Android.SMP.Asimbench-v3.img; sdcard-1g-mxplayer.img
2. I have used the "armv7_gem5_v1_1cpu.dtb" and "boot_emm.arm" binaries
downloaded from http://www.gem5.org/dist/current/arm/
aarch-system-20180409.tar.xz.
<http://www.gem5.org/dist/current/arm/aarch-system-20180409.tar.xz>
3. Made the following changes in the config/common/FSConfig.py :
def makeArmSystem(..)
.....................................
self.cf0 = CowIdeDisk(driveID='master')
self.cf2 = CowIdeDisk(driveID='master')
self.cf0.childImage(mdesc.disk())
self.cf2.childImage(disk("sdcard-1g-mxplayer.img"))
# Old platforms have a built-in IDE or CF controller. Default to
# the IDE controller if both exist. New platforms expect the
# storage controller to be added from the config script.
if hasattr(self.realview, "ide"):
#self.realview.ide.disks = [self.cf0]
self.realview.ide.disks = [self.cf0, self.cf2]
elif hasattr(self.realview, "cf_ctrl"):
#self.realview.cf_ctrl.disks = [self.cf0]
self.realview.cf_ctrl.disks = [self.cf0, self.cf2]
else:
self.pci_ide = IdeController(disks=[self.cf0])
pci_devices.append(self.pci_ide)
...........................................
4. Used the following command:
build/ARM/gem5.opt configs/example/fs.py --machine-type=VExpress_EMM
--os-type=android-ics --cpu-type=MinorCPU --caches
--kernel=/home/abdkhail/gem5/full_system_images/binaries/vmlinux.smp.ics.arm.asimbench.2.6.35
--disk-image=/home/abdkhail/gem5/full_system_images/disks/ARMv7a-ICS-Android.SMP.Asimbench-v3.img
--script=/home/abdkhail/gem5/full_system_images/asimbench_boot_scripts/adobe.rcS
--mem-size=256MB
5. The above commands throw the following error:

Any help would be appreciated.
