| − | == 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
| |
| − | # The kernel and disk image should be placed in ''path_to_gem5_system/binaries'' and ''path_to_gem5_system/disks'' respectively. 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. 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 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')]

| − | == Android Full-System Files ==
| |
| − | These files contain everything you need to get Android, and BBench, up and running on gem5.
