| − | == 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.
| |
| − | | |
| − | # Create a directory where you will place your gem5 full-system files, call this directory ''system''. Inside this directory create two separate directories, one called ''binaries'' and the other called ''disks''.
| |
| − | # Point the ''M5_PATH'' environment variable to this location. E.g, type ''export M5_PATH=path_to_gem5_system/system/''
| |
| − | # Place the kernel in the ''path_to_gem5_system/system/binaries/'' directory
| |
| − | # Place the disk image in the ''path_to_gem5_system/system/disks/'' directory
| |
| − | # 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. E.g., ''path_to_gem5_system/system/binaries/''
| |
| − | # 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')]'' | |
| − | # Assuming you have followed the steps above, and built a full-system version of gem5 for ARM, you should be able to type ''/path_to_gem5_root/build/ARM_FS/m5.fast -b bbench'' to run Android on ARM.

| − | == Android Full-System Files ==

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