Running BBench on Android with Gem5
Everything required to run BBench on gem5 is provided in the next section. You will need the kernel, the disk image (containing BBench), and the rcS script.
- Place the kernel in the path_to_gem5_system/binaries directory
- Place the disk image in the path_to_gem5_system/disks directory
- You will also need to build the ARM bootloader and place it in the same directory as the kernel. The code for the bootloader is typically in path_to_gem5_root/system/arm/simple_bootloader. Simply type make in this directory and the bootloader will be compiled. Copy the resulting boot.arm file to the same directory where you kernel is located.
- The default gem5 scripts look for a kernel called vmlinux.arm.smp.fb.2.6.38.8 and a disk image called android-mbr.img. You will have to either rename the files or create softlinks to them once you have downloaded and untarred them.
- The bbench.rcS file should be placed wherever you keep your rcS scripts. This is typically path_to_gem5_root/configs/boot.
You will also need to modify your Benchmarks.py file to include bbench, i.e. include a line like the following:
'bbench': [SysConfig('bbench.rcS', '256', 'android-mbr.img')]
Note: Android only runs on the ARM ISA.
Android Full-System Files
These files contain everything you need to get Android, and BBench, up and running on gem5.
- Kernel -- Pre-compiled Android kernel and config file.
- Disk Image -- Disk image with a pre-compiled Android Gingerbread file system. This disk image contains all of the files generated during initial boot, as well as a self-terminating version of BBench and BusyBox.
- Clean Disk Image -- Disk image containing only the pre-compiled Android Gingerbread file system. This disk image contains no benchmarks and has never been booted.
- rcS Script -- Script for automating a BBench run on gem5.
