"Vision is not enough, it must be combined with venture. It is not
enough to stare up the steps, we must step up the stairs."
~Vaclav Havel
The Linaro 13.03 release is now available for download!
The 13.03 Linaro release highlights the focused efforts 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, Ubuntu and OpenEmbedded during this release cycle.
The vision of the future of Linux on ARM is brought into focus through
the collaborative efforts of those dedicated to making the vision a
reality one step and one release at a time. The 13.03 cycle
contributions are numerous and continues to venture into new areas of
the ARM ecosystem with each release.
13.03 was a exceptional cycle for the Linaro Android Team. There was a
lot of planning done during the most recent Linaro Connect event in
Hong Kong and some of those plans have already been put into action
during this cycle. The initial bring up of Android for Arndale as an
engineering platform is now complete and we now have a Tiny Android
build for Arndale. Engineers should see an Android with GUI released
for the 13.04 Linaro release cycle. The Origen-Quad build is now
updated with the new bootloaders and the needed changes for
linaro-image-tools have been completed. Bernhard Rosenkränzer,
Android Engineer at Linaro did an exceptional job in making the current
toolchain available natively inside Linaro Android builds. The builds
now include gcc, g++, vim, make, a terminal emulator and a vi-friendly
keyboard; however, compiling the kernel on the board itself has yet to
be tried. The team encourages interested individuals to give a try and
report any bugs. Axel Fagerstedt, Android Engineer at Linaro, did also
excellent job in unifying all the different manifests with the groups
feature. The team started with 17 manifests and have now come to
1 manifest supporting 8 different builds and one additional manifest
for a member build. The released toolchains are now being checked into
a prebuilts/ git repository and pulled in by the manifest as opposed to
being downloaded as separate tarballs. This is the approach used by
AOSP to distribute the toolchain. The Linaro Android Team have also
enabled CTS in LAVA for 4.2. The support for CTS in lava-android-test
was reworked for stability during the upgrade and as a result more than
99% of CTS tests are now passing for Galaxy Nexus with linaro-android
build when tested manually with lava-android-test. CTS was enabled for
the engineering builds; however, more investigation need to be done on
CTS tests that are not getting executed in LAVA for these engineering
builds.
The Linaro Kernel Working Group work for the 13.03 cycle includes
depopulate the Exynos <mach-exynos/include-mach> directory, convert
UX500 to common clk, refactor EHCI controller code, depopulate the UX500
and plat-nomadik <mach/*> and <plat/*>, Android alarm-dev compat_ioctl
support updates, improvements to eMMC Power Management support.
On the Automation and Validation front, LAVA now supports Arndale
booting with UEFI and the bootloader configuration is being done
"on the fly".
The Linaro Graphics Team posted the following patches for acceptance
upstream during the 13.03 release cycle. Version 10 of CMA-ION patches
were posted by Benjamin Gaignard. Tom Gall updated and posted
the Android piglit enablement patches for OpenGL ES 2 as well as
Version 1 of variable-index-* shader-tests extended for Android and
Linux. Version 1 of debugfs support for dma-buf was posted by
Sumit Semwal and Version 9 of DRM FIMD DT support for Exynos4 DT
machine was posted by Vikas Sajjan.
The Linaro Power Management Working Group has upstreamed the dynamic
timer irq affinity--set up the timer irq affinity to the CPU concerned
by the first timer expiration. The cpufreq driver for IKS is now
optimized and analysis of HMP scheduler optimizations using bbench and
their applicability to A15 SMP systems is now complete. Updates to sched
include a modified timer and workqueue framework to allow migration to
non-idle CPUs. Powerdebug was ported and now available on the Android
platform.
The Linaro Toolchain Working Group had a busy 13.03 release cycle as well.
Changes to the Toolchain binaries release include Linaro GCC being
updated to GCC 4.7.2+svn196272, includes arm/aarch64-4.7-branch up to
svn revision 196225. Linaro QEMU 2013.03 was also released earlier this
cycle and is based off upstream (trunk) QEMU --1.4.0 release-- and
includes a number of ARM-focused bug fixes and enhancements. Updates
for this release include ARM KVM support patches which are in sync with
the ABI as committed to the upstream Linux kernel for 3.9--note:
this feature is still under development, but will no longer be subject
to kernel-vs-userspace ABI breaks.
The Linaro Enterprise Group (LEG) announced that the initial GRUB port
on ARM UEFI is now available and the tree can be found on
https://code.launchpad.net/~leif-lindholm/linaro-grub/arm-uefi
We encourage everybody to use the 13.03 release. The download links for

This is to let you know that the migration of lists.linaro.org has been
successfully completed.
As per the email I sent on Wednesday, it may take some time for the new
address of the server to be seen by your computer. You can check this by
trying to connect to the web site:
http://lists.linaro.org/
If you are able to connect and you do not get an error, this means you are
connecting to the new server and you can send email to the lists.
If you experience any problems after the weekend and you find that you
still cannot connect to the server, please reply to this email to let us
know.

Hello
You are receiving this email because you are subscribed to one or more
mailing lists provided by the lists.linaro.org server.
IT Services are announcing planned maintenance for this server scheduled
for *Friday 15th March 2013, starting at 2pm GMT*. The purpose of the work
is to move the service to another server. There will be some disruption
during this maintenance.
In order to ensure that you do not accidentally try to use the service
while it is being moved, the current server will be shut down at 2pm.
A further email will be sent on Friday afternoon to confirm that the
migration of the service is completed. However, due to the way servers are
found, it may take a while before your computer is able to connect to the
relocated service.
After the old server has been shut down, email sent to any of the lists
will be queued, but it is possible that the sending server will still
trying to deliver the email to the old server rather than the new one when
it is started.
It is therefore *strongly* recommended that you do not send any email to an
@lists.linaro.org email address until you can connect to the new service,
which you will be able to test by trying to use a web browser to connect to
http://lists.linaro.org after you receive the email confirming that the
migration has been completed. Since the old service will be shut down, if
you are able to connect, you can be sure you have connected to the new
service.
If by Monday you are still unable to connect to the service or you are not
able to send email to an @lists.linaro.org email address, please send an
email to its(a)linaro.org.
Thank you.

"If you can dream it, you can do it." ~Walt Disney
The Linaro 13.02 release is now available!
The Linaro 13.02 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, OpenEmbedded and Ubuntu during this release cycle.
The 13.02 cycle shows the reality of a dream and desire to unify,
improve and build a better more effective future for Linux on ARM.
Linux on ARM is not a dream, but together --Linaro, its Members, Groups,
and community--continue to make the visons of Linux on ARM a reality.
The Linaro Engineering Group (LEG) released Linaro UEFI 2013.02 which
fixed several bugs targeting the Arndale boards. LEG also added ARM
support to libhugetlbfs, merged into next branch --package is available
from Linaro's Overlay PPA.
During this release cycle the LAVA Team converted the Linaro CI jobs to
lava-test-shell, a black box style testing approach, and the Galaxy
Nexus device is now deployed into the LAVA lab. The Linaro Android Team
has setup the AOSP master build for the Galxay Nexus.
The Linaro Developer Platform team completed the CI bring up for
the Arndale board: Arndale image reports have been added to the LAVA
dashboard and daily tests are run on the board. The team has also
enabled UEFI support in the Arndale hardware pack. The Linux Linaro
kernel 2013.02 was released and is based on the 3.8 upstream Linux
kernel with highlights that include: new kvm topics and big-LITTLE-MP
version master-v15. The Developer Platform Team merged the OpenEmbedded
based SDK with LAMP and is able to build the FaceBook HipHop Virtual
Machine v8 (64bit). In addition, the OpenEmbedded baseline has been
updated to the latest gcc-linaro and linux-linaro releases. Several new
packages such as acpica-unix, acpi-abat, fwts, libhugetlbfs and numactl
are available from Linaro's Overlay PPA to help LEG engineering effort.
Finally, the arm64 Debian/Ubuntu port image is available:
http://lists.linaro.org/pipermail/linaro-dev/2013-February/015534.html.
A call to 'the distros' has been made to take this work forward from here.
People interested in Debian and Ubuntu on 64-bit arm hardware need to
step up and help out.
The Linaro Kernel team was able to update the AB8500 driver with
pinctrl patches and update the Snowball platform to now use sparse IRQs.
As part of the single zImage work, the team started to depopulate
the Exynos and Ux500 <include/mach> and <include/plat> directories.
Also as part of this, with much work from the community, final removal
of <mach/id.h> subdirectory has landed in Linus's tree. The team also
started to work on refactoring of the USB EHCI controller code so that
we can build multiple USB host types into a single binary kernel.
As part of the storage work in Kernel Working Group, work has begun on
improvements to the eMMC Power Management support and the team is
digging into how to use the enchanced area of eMMC devices for EXT4
journaling metadata. Additionally, as part of the team's Android
upstreaming efforts, the Android keyreset driver has been accepted into
the 3.9 kernel and Android alarm-dev compat_ioctl support has been added.
The Linaro Toolchain Team released Linaro GCC 4.7-2013.02-01 based off
GCC 4.7.2+svn195745 and includes arm/aarch64-4.7-branch up to svn
revision 195716, support for Cortex-A7 backported from trunk.
The 2013.02 Linaro Toolchain Binaries release were updated to latest
Linaro GCC 4.7 2013.02-01 which included upgrades for binutils to
v2.23.1, eglibc to v2.17 and the kernel header to v3.7.
We encourage everybody to use the 13.02 release. The download links for
all images and components are available on our downloads page:

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:

blue print of the desired result." ~Stephen Covey
We are pleased to announce the release of Linaro 13.01.
With the first release of the calendar year, Linaro is happy to highlight
the ingredients that make up the deliverables, again produced by Linaro
Teams – Working Groups, Enterprise Group, Landing Teams and Platform Teams –.
Linaro anticipates another great year of Linux on ARM development
celebrating new members and producing some cutting edge advances.
The Developer Platform Team has enabled 64bit HipHop VM development in
OpenEmbedded, continued to merge ARMv8 support into the OpenEmbedded
platform and upstream, engaged initial support for the Arndale board
and released Linux Linaro 3.8-rc4 2013.01.
For the Android team, it was a busy cycle. The initial changes to
android-build page for the new build program have been done. They are
finally moving towards consolidation of manifests: Origen and Versatile
Express can now be synced and built from the same manifest. The Team is
happy to announce linaro-android-tools which is directed towards kernel
developers. The tool can be used to update kernel and initrd in Android
without having to remove the SDcard. They have also updated the third
party benchmarks to use the uiatomator testing framework introduced in
Jelly Bean. Android hardware pack support has been added.
The Linaro Enterprise Group (LEG) has released Linaro UEFI 2013.01.
The highlights include fixes for native building of UEFI on ARM
platforms and improvements to flashing images on Arndale board and
enable native building for PandaBoard.
The Power Management Group hosted a big.LITTLE sprint in Cambridge led
by Amit Kucheria. A meeting of minds between ARM, Linaro and the
community succeeded in achieving enhanced focus and a more defined
roadmap for the big.LITTLE story. Topics included clearly defined
benchmarking to determine the effectiveness of the platform, enhanced
verification to augment the traditional kernel power/performance testing,
and a well defined roadmap for big.LITTLE on Android. In related
big.LITTLE MP development, version 14 of the big.LITTLE MP tree has
been released.
We encourage everybody to use the 13.01 release. The download links for
all images and components are available on our downloads page:
http://www.linaro.org/downloads/

"Identify your problems but give your power and energy to solutions."
~Tony Robbins
We are pleased to announce the release of Linaro 12.12.
The Linaro 12.12 release highlights energy 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 12.12 release rounds
out a great year of successes that prove how the collaborative efforts
of Linaro, together with its members, partners and community continue
to build upon the future of Linux on ARM.
"Just look at the engineering that Linaro has been involved with.
big.LITTLE, kernel consolidation, UMM, ARMv8 and the list goes on.
It’s not just hacking code though, Linaro is thinking carefully about
itself, re-engineering itself for the next phase in its evolution.
“Start up” was 2010, “Establishment” was 2011 and 2012 has been “Growth”.
What’s 2013 going to be all about? Just wait and see," said David
Rusling, Linaro CTO in his 2012 year end summary.
The 12.12 release highlights include the Linaro Android team has
upgraded its builds to to 4.2.1, enabled WiFi on PandaBoard for 4.2.1
and audio on the Origen 4210. Additionally the team released its 12.12
toolchain this cycle. Earlier this month, the 3.7 Linux Kernel was
released and the Linaro Android team rebased the perf patches.
As we look at the achievements of the Linaro Developer Platform,
we note that the Linaro baseline images for Ubuntu are now based on
Quantal Quetzal otherwise known as Ubuntu 12.10 and initiate the
transition from Evaluation Builds to Engineering Builds. The Linaro
U-Boot 2012.12 which is based on U-Boot v2013.01-rc1 was released and
includes support for Origen quad (4412) and Arndale (5250) boards.
The Linaro Power Management team had a very busy cycle: optimizing
big.LITTLE IKS (In Kernel Switcher) for release to members, integrating
the big.LITTLE MP via the Intergration tree, adding improvements to
help solve tasking packing around the power-aware scheduler, IKS and MP
benchmarking for power and performance, adding thermal framework
enhancements for non-ACPI platforms, updating Powertop for ARM
platforms and adding cpuidle support for multi-cluster SoCs.
The Linaro Toolchain Team announced updates: Linaro GCC 4.7 2012.12 was
released and is based off GCC 4.7.2+svn194184 which gives better 64 bit
shifts in NEON, updates the arm/aarch64-4.7-branch up to svn revision
194154. Linaro Toolchain Binaries for 2012.12 was released and updated
to latest Linaro GCC 4.7 2012.12 and Linaro GDB 7.5 2012.12.
LAVA has seen updates and improvements this cycle as well as support
for the 4.2.1 Linaro Android images were added, Other improvements on
the LAVA front include increases IP address space from 255 to 65k in
the lab, image reports for the automated testing of OpenEmbedded
builds is now available, a new server was added tothe validation lab
for audio, power measurement, and SD-mux capable devices. LAVA can now
execute Versatile Express jobs using the test images DTB and
VExpress-tc2 boards have been converted to use IKS. A 64-bit virtual
machine was added to lava-cloud for the Linaro Toolchain team's use as
well. The user interface for finding, viewing and downloading
attachments in the LAVA dashboard was improved and signal handlers can
be written in shell and bundled with the tests themselves.
We encourage everybody to use the 12.12 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:

The Linaro 12.11 release is now available!
The Linaro 12.11 release cycle highlights the determination and hard
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 12.11 release is another example of how Linaro
works together with its members, partners and community to continue to
build the future of Linux on ARM.
Looking over the higlights from the 12.11 release cycle, it's easy to
see how the momemtum and energy from LCE12-Copenhagen carries over and
our teams consistantly meet and exceed the goals set in the Linaro
Connect sessions. Our Android team has updated the platform to AOSP 4.2
on all our supported boards, and Android evdev is now upstreamed and
used in AOSP 4.2.
As we look over improvements to the Linaro toolchain, it is notable
that Linaro GCC now includes the arm/aarch64-4.7-branch (ARMv8).
The Developer Platform team reports that the initial GRUB support for
ARM is now available, provided by our Linaro Enterprise Group and
marking its first component.
The Power Management Working Group continues its progress on big.LITTLE
MP by delivering the v11 and v12 branches, as the Graphics Working Group
notes that there is a new GLMark2 release which demonstrates shadow
mapping. Additionally our LAVA team reports that the NI Battery
Simulator is now available in the lab and can now be accessed remotely.
We encourage everybody to use the 12.11 release. The download links for
all images and components are available on our downloads page:

“A dream doesn't become reality through magic; it takes sweat,
determination and hard work.“ ~ Colin Powell
The Linaro 12.10 release is now available!
The Linaro 12.10 release cycle highlights the determination and hard
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 12.10 release is another example of how Linaro
works together with its members, partners and community to continue to
build the future of Linux on ARM.
On the ARMv8 front, Linaro is now making early ARMv8 images available
to interested developers. For a primer on the ARMv8 architecture,
the AArch64 execution state and the A64 instruction set, please visit
the ARM portal:
http://www.arm.com/products/processors/instruction-set-architectures/armv8-…
While there is currently no ARMv8 hardware available, ARM and Linaro
have developed support for AArch64/A64 against virtual platforms and
started sending the resulting patches to various open source projects.
With the Linaro provided downloads and with ARM’s Fast Models virtual
platform, you may boot a virtual ARMv8 system and run 64-bit binaries.
These downloads are currently in beta, but they should just work and
we are looking towards including them as part of our monthly releases.
For more information on these ARMv8 images, please take a look at
the Linaro Engineer pages on the Linaro website:
http://www.linaro.org/engineering/armv8
Work on big.LITTLE continues as the Linaro Kernel Working Group
highlights its completion of TC2 support; noting that TC2 now boots
with the latest IKS tree. Five new test cases have been added to handle
simultaneous thread switching, important bugs such as Switcher Thumb-2
bug and Switcher deadlock issue when working on the memblock_steal(),
vlock remaining locked under certain conditions were fixed along with
and updated focus to run benchmarks with the latest IKS on TC2 to find
optimization opportunities.
While some wondered if the idea of a consolidated kernel in the ARM
ecosystem would remain a dream and something developers only longed for,
the Linaro Kernel Working Group continues to work toward making that
dream a reality and during the 12.10 Linaro development cycle announced
that they will demo their work on their continued efforts on the single
zImage kernel. Mark Orvek, Director for the Kernel Working Group at
Linaro in a Google+ Hangout on Air discussion hinted to what attendees
could expect to see at the LCE 12 -Copenhagen Demo Friday event. Orvek
indicated that Deepak Saxena would be demo'ing a single kernel across
several member boards. The full recorded Hangout is available on:
http://youtu.be/t71JNNO6IDo
We encourage everybody to use the 12.10 release. The download links for

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:

“There is a real magic in enthusiasm. It spells the difference between
mediocrity and accomplishment.“ ~ Norman Vincent Peale
The Linaro 12.09 release is now available!
The Linaro 12.09 release cycle highlights the combined work and
enthusiasm 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 12.09 release is another example of how Linaro
succesfully –together with its members, partners and community–
continue to build the future of Linux on ARM.
Zach Pfeffer, the Linaro Android Team Tech Lead, explains to the Linaro
Release team what he and his team have accomplished during this cycle.
Linaro’s patches to AOSP are now available on Jelly Bean and Linaro
Android users should now see a 15% performance bump in their Android
builds when combined with the Linaro toolchain. Developers now have
another MALI based accelerated platform to work with as the Snowball
graphics enablement is now available on the Linaro Jelly Bean build.
The team also analyzed 10 of the most popular Android benchmarking
tools: AndEBench, AndEBench Java, Linpack, CaffeineMark,
Antutu 2D and 3D, NBench, Quadrant, I/O Benchmark and Vellamo.
Additionally, the team has put together the NI PXIe-4154 based power
measurement system which will allow the instrument to be easily
integrated into LAVA. Also there is now an AOSP test automation
framework that is able to automatically read and execute in-tree AOSP
tests.
"During the 12.09 cycle the team started early work on a minimal ARMv8
bootstrap, and we already have a very minimal rootfs with some parts to
help other developers that want to get involved with the porting,"
says Ricardo Salveti, Developer Platform Team Tech Lead.
"This work will be critical for the future of Linux on ARMv8, as
the major GNU/Linux distributions can use it as base to bootstrap and
support this new architechture." In addition to the work highlighted
by Salveti, the Developer Platform team also updated the kernel and
test components for the big.LITTLE project, made substantial progress
on the Debian/Ubuntu Perl and Python multi-arch/cross-build support,
and noted that the hardware packs for Versatile Express, Origen and
PandaBoard now include the support for UEFI and can be selected while
flashing the image with linaro-media-tools.
We encourage everybody to use the 12.09 release. The download links for
all images and components are available on our downloads page:

The Linaro 12.09 release is now available!
The Linaro 12.09 release cycle highlights the combined work and
enthusiasm 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 12.09 release is another example of how Linaro
succesfully –together with its members, partners and community–
continue to build the future of Linux on ARM.
Zach Pfeffer, the Linaro Android Team Tech Lead, explains to the Linaro
Release team what he and his team have accomplished during this cycle.
Linaro’s patches to AOSP are now available on Jelly Bean and Linaro
Android users should now see a 15% performance bump in their Android
builds when combined with the Linaro toolchain. Developers now have
another MALI based accelerated platform to work with as the Snowball
graphics enablement is now available on the Linaro Jelly Bean build.
The team also analyzed 10 of the most popular Android benchmarking
tools: AndEBench, AndEBench Java, Linpack, CaffeineMark,
Antutu 2D and 3D, NBench, Quadrant, I/O Benchmark and Vellamo.
Additionally, the team has put together the NI PXIe-4154 based power
measurement system which will allow the instrument to be easily
integrated into LAVA. Also there is now an AOSP test automation
framework that is able to automatically read and execute in-tree AOSP
tests.
"During the 12.09 cycle the team started early work on a minimal ARMv8
bootstrap, and we already have a very minimal rootfs with some parts to
help other developers that want to get involved with the porting,"
says Ricardo Salveti, Developer Platform Team Tech Lead.
"This work will be critical for the future of Linux on ARMv8, as
the major GNU/Linux distributions can use it as base to bootstrap and
support this new architechture." In addition to the work highlighted
by Salveti, the Developer Platform team also updated the kernel and
test components for the big.LITTLE project, made substantial progress
on the Debian/Ubuntu Perl and Python multi-arch/cross-build support,
and noted that the hardware packs for Versatile Express, Origen and
PandaBoard now include the support for UEFI and can be selected while
flashing the image with linaro-media-tools.
We encourage everybody to use the 12.09 release. The download links for
all images and components are available on our downloads page:

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

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.
