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 in the /benchmarks/dacapo directory.
Installing Oracle-Sun Java on an Ubuntu Image for ARM gem5
Download the standard edition(SE) of Java 7; the SE version is the free version of Java available from Oracle. Make sure to get the headless, SoftFP version of the JRE for ARMv6/7 from here. You may need to register with Oracle before being allowed to download. Once you have this, untar it.
Setup the Java Directory
//mount the image sudo mkdir /mnt/ubuntu-gem5 sudo mount -o loop,offset=32256 arm-ubuntu-natty-headless-java.img /mnt/ubuntu-gem5 //setup the Java install directory and copy the Java directory over to your image cd /mnt/ubuntu-gem5/usr/lib sudo mkdir jvm cd ./jvm sudo cp -a /path_to_jre/jre_dir . sudo ln -s ./jre_dir java-7-sun
Install Java
cd /mnt/ubuntu-gem5 sudo mount -o bind /proc ./proc sudo mount -o bind /dev ./dev sudo mount -o bind /sys ./sys sudo chroot . exec ./bin/bash //now install Java cd /usr/lib/jvm update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-7-sun/bin/java 1 update-alternatives --install /usr/bin/keytool keytool /usr/lib/jvm/java-7-sun/bin/keytool 1 //setup .jinfo file echo "name=java-7-sun" > .java-7-sun.jinfo echo "alias=java-7-sun" >> .java-7-sun.jinfo echo "priority=1" >> .java-7-sun.jinfo echo "section=non-free" >> .java-7-sun.jinfo echo "jre java /usr/lib/jvm/java-7-sun/bin/java" >> .java-7-sun.jinfo echo "jre keytool /usr/lib/jvm/java-7-sun/bin/keytool" >> .java-7-sun.jinfo //update java alternatives update-java-alternatives -s java-7-sun
Once you have unmounted the image, you should be able to run Java with this disk image. Boot this image on gem5 and, from the terminal, type java -version to verify the Java version on your image. E.g., the version tested on gem5 is:
root@gem5sim:~# java -version java version "1.7.0_04-ea" Java(TM) SE Runtime Environment for Embedded (build 1.7.0_04-ea-b20, headless) Java HotSpot(TM) Embedded Client VM (build 23.0-b21, mixed mode)
