We are pleased to announce the release of Linaro 12.04.

The Linaro 12.04 release highlights the precision, expertise and talent
which all of the Linaro Teams – Working Groups, Landing Teams and
Platform Teams – use to deliver influential updates and stimulating new
features that are integrated on top of Android and Ubuntu. We, together
with our members, partners and community continue to build upon the
future of Linux on ARM and the 12.04 release is one more step in the
excellent execution of those plans.

"This release integrates the ARM Fast Models. Using Fast Models enables
us to engineer and test architectural features well before production
silicon chips are available from our members. The most recent major
project that is seeing the benefit of this is our work with big.LITTLE
integrated kernel switching and KVM (using the Cortex-A15's
virtualization mode)" said Linaro CTO David A Rusling, "these
cycle-accurate architectural models are essential in our mission to
avoid fragmentation and accelerate our member's time to market."

During the Linaro 12.04 release cycle the Developer Platform Team
migrated the Linaro Evaluation Builds (LEB) to the Ubuntu 12.04 LTS
(Precise Pangolin) based images. These new images are built for the ARM
hard float (armhf) images and Linaro U-Boot is now based on the latest
upstream release – v2012.04.1. Additionally, the Developer Platform
images now provide support for the big.LITTLE integrated switcher and
A15 Fast Models with KVM kernel, as well as testing coverage of
the big.LITTLE project for both the reference and integrated switcher.

The Linaro Android team delivered the multimedia enablement for the
Snowball and have updated all builds to AOSP ICS 4.0.4_r1.1. Also
included as of this cycle are updated base toolchain components – MPFR
and GMP. The Linaro Android Team ported stressapptest to Android for
big.LITTLE testing and like the Developer Platform team implemented and
ran weekly big.LITTLE tests.

The Infrastructure, Graphics, Kernel, Multimedia, Toolchain, and
Validation teams all had updates and new features added into this
release which are covered in more detail on the release wiki.

We encourage everybody to use the 12.04 release. The download links for
all images and components are available on our downloads page:


See the detailed highlights of this release to get an overview of what
has been accomplished by the Working Groups, Landing Teams and Platform
Teams. The release details are linked from the “Details” column for
each released artifact on the release information:


Using the Android-based images

The Android-based images come in three parts: system, userdata and boot.
These need to be combined to form a complete Android install. For an
explanation of how to do this please see:


If you are interested in getting the source and building these images
yourself please see the following pages:


Using the Ubuntu-based images

The Ubuntu-based images consist of two parts. The first part is a hardware
pack, which can be found under the hwpacks directory and contains hardware
specific packages (such as the kernel and bootloader). The second part is
the rootfs, which is combined with the hardware pack to create a complete
image. For more information on how to create an image please see:
