The Linaro 12.08 release is now available!
The Linaro 12.08 release highlights the combined work of all the Linaro
Teams – Working Groups, Landing Teams and Platform Teams – who have
provided all the updates and new features that are integrated on top of
Android and Ubuntu during this development cycle. The 12.08 release is
another example of how Linaro succesfully--together with its members,
partners and community--continue to build the future of Linux on ARM.
12.08 was a very busy cycle for the Linaro Android platform team,
"During the cycle our number one goal was to create stable Jelly Bean
builds from AOSP for all of the platforms we support," said Zach
Pfeffer, Tech Lead for the Linaro Android Team. "Not only did the team
achieve this goal, but also continued to create a world class Android
benchmarking platform, made it easier for people to connect their Jelly
Bean based builds to the network by integrating the Ethernet
Configuration Manager and automated many of the tests in the AOSP
codebase," added Pfeffer. The Linaro Android team is already looking
toward the Linaro 12.09 development cycle and according to Pfeffer,
"We’re planning on getting each baseline working with Linaro’s
linux-linaro upstream tracking kernel, continuing to improve our
benchmarking infrastructure and maybe, just maybe having a very
preliminary 64-bit Android build (fingers crossed)".
The Developer Platform Team announced USB Host enablement is now
available in LAVA and that all packaged linux-linaro kernels are now
cross-compiled and boot tested via LAVA before they are uploaded to
Linaro Overlay PPA. Additionally, U-Boot-Linaro is now based on
the latest upstream release--v2012.07.
We encourage everybody to use the 12.08 release. The download links for
all images and components are available on our downloads page:
http://www.linaro.org/downloads/

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:
http://wiki.linaro.org/Platform/Android/ImageInstallation
If you are interested in getting the source and building these images
yourself please see the following pages:
http://wiki.linaro.org/Platform/Android/GetSourcehttp://wiki.linaro.org/Platform/Android/BuildSource
Note: tilt-tracking build (LEB) doesn't contain accelerated SGX support
(only framebuffer video). For a full enablement support (graphics and
multimedia), please use OMAPZoom build from our Developers and Community
Builds section. In addition to those builds, a tilt-stable and an AOSP
based builds are provided.
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:

The Linaro 12.07 release is now available!
The Linaro 12.07 release highlights the quality, effort and work of all
the Linaro Teams – Working Groups, Landing Teams and Platform Teams – who
have provided all the updates and new features that are integrated on top
of Android and Ubuntu during this release cycle. The 12.07 release is
another example of how Linaro, together with its members, partners and
community continue to build upon the future of Linux on ARM one release
and line of code at a time.
The LAVA team (http://www.linaro.org/about/meet-the-team/lava) added new
test views for its daily testing processes as well as updates to the way
its deployment tool works by implementing a new method which uses
zc.buildout which works consistently and in a repeatably fashion.
(http://www.linaro.org/linaro-blog/2012/07/24/lava-deployment-improvements/)
Linaro continues to make progress in big.LITTLE development as the ARM
Landing Team (http://www.linaro.org/about/meet-the-team/arm-landing-team)
delivers support for ARM TC2 (TestChip2) tile for the vexpress board.
(TC2 is a big.LITTLE core with 2 Cortex A15 and 3 Cortex a7 processors).
The Linaro Power Management group delivers its first submissions of
big.LITTLE MP functionality (git://git.linaro.org/arm/big.LITTLE/mp.git)
during the 12.07 release cycle as well.
The LAVA team was able to release the first boot log
(https://plus.google.com/u/0/118153619948280443975/posts/V2dzB1PnP4r )
from the new big.LITTLE Versatile Express which is currently located in
its LAVA lab. Additionally, the Developer Platform team reports that the
Linaro ALIP is now using LXDE as the default enviroment, with a reduced
image for better performance at ARM targets, such as Vexpress and
FastModels. Linux Linaro updated on top of the latest upstream
release (3.5), which reflects the latest changes and development available
at Linaro, such as big.LITTLE MP.
The Linaro Android team added experimental baselines for the Galaxy Nexus
(https://android-build.linaro.org/builds/~linaro-android/galaxynexus-jb-gcc4…)
and Pandaboard (https://android-build.linaro.org/builds/~linaro-android/panda-jb-gcc47-tilt…)
as part of our ongoing Jelly Bean transition efforts. Also, deployed this
month in LAVA were the Android benchmarking apps for Pandaboard, Snowball
and Origen which included vellamo, quadrant, nbench, linpack, glbenchmark,
geekbench, caffeinemark, antutu, and AndEBench.
In addition to these improvements the Developer Platform team notes that
Kernel packages are updated to reflect the latest development trees from
Linux Linaro (lct/ll-3.5 and llt-3.4) and the Landing Teams. CI jobs for
the Ubuntu Kernel Packages are now cross compiled at Jenkings, then pushed
directly to the Kernel PPA which reflects the reduction the time it takes
for the kernel package to respin.
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.

"Perseverance is not a long race; it is many short races one after another."
~Walter Elliott
We are pleased to announce the release of Linaro 12.05.
Updates, new feature implementations, new ways to use the member boards
are all the short races in which we persevere in our efforts to support,
design, and build the future of Linux on ARM.
Linaro release 12.05 comes on the cusp of Linaro Connect in Hong Kong
where over 200 ARM developers, engineers, and more have descended on
the Gold Coast hotel to present, discuss and develop features,
infrastructure and optimizations for the Linux kernel, Android, Ubuntu.
During this Q2.12 Linaro Connect the spotlight is on the following
technologies:
* ARM big.LITTLE implementation
* Multicore power management and scheduling
* SoC BSP maintainance, cost reduction and upstreaming
* A15 Virtualization
* SoC Unified Memory Management
* ARM for the Enterprise: Servers and Beyond
Linaro engineers will "show off" demos which touch on the sessions and
support developed not only during this and past cycles, but refined as
part of the Q2.12 Linaro Connect and will highlight this work as part
of the Demo Friday event:
http://connect.linaro.org/events/linaro-connect-q2-12-demo-friday/
As part of the Linaro Connect Q2.12 event Linaro also took risks with
new free technologies now being offered as part of the Google+--Hangouts
on Air. All public sessions were live streamed to remote participants.
Our Android team even has this technology running on Samsung's Origen
board. The amazing story is that less than 6 months ago using
Google+ Hangouts wasn't possible on an ARM platform with an open source
distribution.
We encourage everybody to use the 12.05 release. The download links for

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:

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:
http://wiki.linaro.org/Platform/Android/ImageInstallation
If you are interested in getting the source and building these images
yourself please see the following pages:
http://wiki.linaro.org/Platform/Android/GetSourcehttp://wiki.linaro.org/Platform/Android/BuildSource
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:

Hi all,
The graphics working group is pleased to announce the 2012.04 release
for the following components:
- Unity 3D desktop shell
* All OpenGL|ES changes for the unity plugin itself as well as the nux
library are in their respective launchpad trunk branches.
* compiz-core and compiz-plugins-main have updated release tarballs which
reflect rebasing on the latest launchpad trunk branches.
* The distro patch based upon the Linaro compiz branches has been applied to
the Precise packages, so support for the Unity 3D desktop shell on ARM is
available directly from the Precise archives.
- glcompbench
* 'blur' test has been updated to handle windows that are added to the canvas
after the test is initialized.
* Fix for bug 984058 (glcompbench exits when closing a window tracked by the
canvas).
- glproxy
* Fully document the API, and integrate the generation of the documentation
with the build; enabled at build time by configuring with --build-docs.
These are all available for download from their respective project
pages, conveniently linked from the project group page at:
https://launchpad.net/linaro-graphics-wg
The release for the linaro-mm-sig project is being rolled up into the
linux-linaro-core-tracking branch of
git://git.linaro.org/kernel/linux-linaro-tracking.git for this cycle,
and should see updates between cycles, as well moving forward.
Enjoy!
cheers,
Jesse
