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.
