DaCapo benchmarks

This page describes how to get the Oracle-Sun JRE version 7 working on a disk image for use with ARM gem5. This will allow you to use the DaCapo benchmarks, which are on the Ubuntu image for gem5 ARM.

• Get the ARM full-system files and untar them.
• Get the headless version of the JRE for ARMv6/7 from Oracle. Once you have this, untar it.
• Create a mount point and mount the Ubuntu image:
  • sudo mkdir /mnt/ubuntu-gem5
  • sudo mount -o loop,offset=32256 arm-ubuntu-natty-headless.img /mnt/ubuntu-gem5
• Make the Java install directory and copy the Java directory over:
  • cd /mnt/ubuntu-gem5/usr/lib
  • sudo mkdir jvm
  • sudo cp -a /path_to_jre/jre_folder /mnt/ubuntu-gem5/usr/lib/jvm
