This page describes all the necessary files and modifications to run Android and AsimBench on gem5 using the ARM ISA. BBench-gem5 introduces more detailed information about how to set Android running on gem5, and how to build Android File System and Kernel.

Android Full-System Files

These files contain everything you need to get Android, and AsimBench, up and running on gem5.

All these files can be downloaded from here.

• vmlinux.smp.ics.arm.asimbench.2.6.35 -- Pre-compiled Android kernel. Compared to the 2.6.35 version Android kernel, this kernel only modifies the screen size of simulated mobile device, which is specified to 800 x 480.

• ARMv7a-ICS-Android.SMP.Asimbench.tar.gz -- Disk image with a pre-compiled ICS file-system. This disk image contains all the files for all the applications included in AsimBench. The related files are mainly stored in the directories data/app, data/data of the image.

• sdcard-1g.tar.gz -- Disk image with applications' data. This disk image simulates the SDcard partition of mobile devices.

• {k9mail, adobe, sinaweibo, ...}.rcS -- Execution scripts for each application in gem5.

Running AsimBench on Android with gem5

• Both the disk image and the SDcard image should be loaded by gem5, and the SDcard image is automatically mounted under the directory /mnt/sdcard of Android file system by default.

 Here is an example of loading two disk images in gem5. In the file config/common/FSConfig.py
   def make ArmSystem(...)
       ...
       self.cf0 = CowIdeDisk(driveID='master')
       self.cf2 = CowIdeDisk(driveID='master')
       self.cf0.childImage(mdesc.disk())
       self.cf2.childImage(disk("sdcard-1g.img"))
       # default to an IDE controller rather than a CF one
       # assuming we've got one
       try:
           self.realview.ide.disks = [self.cf0, self.cf2]
       except:
           self.realview.cf_ctrl.disks = [self.cf0, self.cf2]
       ...
