We are pleased to announce the release of Linaro 12.06.
Linaro 12.06 contains components delivered by all Linaro Teams
--Working Groups, Landing Teams and Platform Teams-- and brings an
abundance of exciting updates and new features which are integrated on
top of Android and Ubuntu. Linaro through these updates, fixes, and new
features continue to build the future of Linux on ARM and the 12.06
Linaro release delivers another winning combination off these components.
In the 12.06 release, the Linaro Android Team delivers multimedia
enablement on AOSP and those patches are now under review. The team now
has automated benchmarking applications (Monkeyrunner) working on both
the PandaBoard and Snowball boards.In addtion to the benchmarking now
working on PandaBoard; perf for Andoid on PandaBoard has been submitted
to the Linaro kernel maintainers for other ARM based processor boards
and lkml. For this release Linaro Android was also updated to Android
version 4.0.4 r2. Also of note; the video that Nicolas Charbonnier shot
during the Demo Friday event at Linaro Connect Q2.12 in Hong Kong about
the improvements to the Linaro Android toolchain continues to create
interest in this teams work and the future of the possibilities of
Android performance. More information on other exciting news
surrounding Linaro Android can be found in the release highlights.
The Linaro Developer Platform Team announced that the Kernel config
fragments are now being used by all kernel packages in the Linaro
Evaluation Builds (LEBs) and this includes one single fragment for the
Ubuntu Specific configs which allows for all builds to behave in a
similar fashion. Other updates include all Linaro Linux kernel packages
were updated to the latest development trees from Linux Linaro and the
Linaro Landing Teams. The Linux Linaro maintenance scripts are now
available and can be found on git.linaro.org; additionally improvements
have been made to the instructions and scripts to allow easier
cross-builing of packages using multi-arch with Ubuntu.
We encourage everybody to use the 12.06 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
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:

"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
all images and components are available on our downloads page:

~Lou Holtz
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.

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!

We are pleased to announce the release of Linaro 12.03.
Linaro 12.03 contains components delivered by all Linaro Teams –Working
Groups, Landing Teams and Platform Teams– and brings an abundance of
exciting updates and new features which are integrated on top of Android
and Ubuntu. We, together with our members, partners and community
continue to build future of Linux on ARM and the 12.03 release is one more
step toward that future.
During the 12.03 release cycle, the Linaro Toolchain Working Group
announced the 12.03 release of both Linaro GCC 4.6 and Linaro GCC 4.5.
Linaro GCC 4.6 12.03 is the thirteenth release in the 4.6 series and is
based off the latest GCC 4.6.3 release; it contains a new scheduler
pressure pass, implements new instructions, and contains a number of bug
fixes. Linaro GCC 4.5 12.03 is the nineteenth release in the 4.5 series and
is based off the latest GCC 4.5.3+svn184976 release; this is a maintenance
only update. Additionally, the Linaro Toolchain Working Group annouced the
release of Linaro QEMU 12.03 which is based off upstream (trunk) QEMU,
it includes a number of ARM-focused bug fixes and enhancements.
The Linaro Multimedia Working Group during the 12.03 Linaro release cycle
added updates to the following: pulseaudio and alsa, initial source code
only drop of TinyHal, libav AAC optimization and Speex for Android and
Linux.
The Graphics Working Group also announced its contributions to the 12.03
release adding updates and improvements to the following components:
glmark2, glcompbench, glproxy, nux and Unity.
Pre-built release images for the Android and Ubuntu LEBs are currenly
available with each of the Linaro monthly releases; however, new with the
Linaro 12.03 release is that now developers can get daily pre-builds of the
Ubuntu LEB which will be based on the current release of Ubuntu. Pre-built
images can be found at snapshots.linaro.org.
"The introduction of prebuilt images for Linaro's daily output will widen the
reach of Linaro's integrated evaluation builds. One advantage to the
availability of these daily builds is that it gives professionals using Windows
and MacOSX the opportunity to more easily install these images using the
standard tools which are commonly available in these environments", says
Alexander Sack, Technical Director, Linaro Platforms.
Linaro Member Services Program Director, Vicky Janicki, says “Pre-built
images save time and effort for our Members and their customers as a
starting point for their work. Instead of hunting in different places for code,
images, and working out licensing agreements, an engineer simply goes to
the Linaro download site knowing all the pieces will work together. The
engineer now has access to a current Linux kernel in less than 10 minutes.”
Additional items of interest from the Linaro 12.03 release cycle include:
Registration is now open for the Linaro Connect Q2.12 event being held at
the Gold Coast Hotel in Hong Kong from 28 May through 1 June, and
brings together some of the best software developers from the Linaro
ecosystem to help develop and plan the future of Linux on ARM.
A 'Call for Submissions' for Linaro Connect Q2.12 Plenaries was also
announced --Do you have a great idea you would like to present to the
Linaro Connect Q2.12 attendees? Want to share a Linaro success story
and motivate, inspire, excite or educate attendees? Then this is an
opportunity for you to get involved in this Linaro Connect event. More
information on how to submit your plenary talk ideas can be found in on the

Hi all,
Somehow, I completely forgot about the release for the unity-gles
project. All OpenGL|ES enablement for the Ubuntu Unity plugin (the
Unity3D "shell") and the nux library has been merged into the
respective trunks on launchpad for those projects (lp:unity, lp:nux),
so Linaro will not be releasing those. There are 2012.03 release
tarballs for compiz itself (both compiz-core and compiz-plugins-main)
at https://launchpad.net/unity-gles. These will support Precise only,
due to external library dependencies.

I'd like to announce a change in how the Linaro Toolchain group notify
about our monthly releases. In the past we've sent one email per
product to the linaro-announce list. From this week forward a summary
of all products will be included in the main, end of month
announcement instead.
We'll continue to send a per product emails to the linaro-toolchain
list when the mid-month release is available. If you'd like to get
things two weeks early, please subscribe[1]. You can filter on the
word '[ANNOUNCE]' to filter out the development chatter. A RSS feed

Additional highlights from Linaro Connect Q1.12 from the Linaro Dev Platform
and Multimedia Teams include:
By using proper image builds and validation with LAVA the Linaro Dev Platform
can ensure all images are properly tested as soon they are published. A new
proposal for the linux-linaro tree was introduced which will make
the linux-linaro tree the single reference for kernel work at Linaro and should
always be working against latest upstream RC release.
The Linaro Dev Platform team will now be responsible for packaging and
maintenance of all the LT kernel flavors. Responsibilities will include
validating the kernel daily with LAVA, and only publishing the kernels
(which pass validation testing) to be used by the LEB images (until the new
linux-linaro tree is in place).
During both Linaro Connect Q1.12 and the Embedded Linux Conference (ELC),
Rob Clark and Sumit Semwal demo'd v4l2+drm buffer sharing with dmabuf as part
of the Unified Memory Management work carried out by Linaro and its members.
The Multimedia team worked to improve the validation outlook on LAVA for audio
and created test definitions which are related to e2e tests-- which will run on
LAVA for Ubuntu and Android, as well as a number of benchmarks (LJT, Realvideo).
The first internal demo of the dashboard for Graphics benchmarks with glmark2
was showcased at this Linaro Connect and the Linaro Graphics team notes that
even at this early stage the dashboard shows great promise to detect graphics
related performance regressions. The CMA testing suite on LAVA was also updated
and follows the newest versions of CMA patches--Contiguous Memory Allocator -
part of the Unified Memory Management effort.

Linaro 11.12 Released!
"We are what we repeatedly do. Excellence, therefore, is not an act but a
habit." ~Aristotle
Linaro is pleased to announce the release of Linaro 11.12, a continuance of
Linaro releases delivered on a monthly cadence. The Linaro 11.12 release is
also the last release for 2011 calender year and continues to deliver
excellence and quality that members can expect to throughout 2012.
This release includes components delivered by all Linaro Teams: Working
Groups, Landing Teams and Platform Teams. This effort brings an abundance
of exciting updates and new features, integrated on top of Android and Ubuntu.
Now available with this release are the Linaro Android builds of Ice Cream
Sandwich (ICS) supporting accelerated graphics on two of its member's low cost
development boards; the Samsung Origen board and the ST-Ericsson Snowball
board. The accelerated graphics on both the Samsung Origen board and the
ST-Ericsson Snowball board that are now available are based on chips
incorporating a dual-core ARM Cortex-A9 processor and an ARM Mali-400 graphics
processor: Samsung's Exynos 4210 and ST-Ericsson's NovaThor9500.
http://www.linaro.org/accelerated-builds-of-android-ice-cream-sandwich-now-…
In addition to Snowball from ST-Ericsson, Origen from Samsung and PandaBoard
from TI, Linaro's Android Team and its Freescale Landing Team have set the
groundwork for bringing acceleration to the i.MX53 by stabilizing and
improving ICS on the Quick Start board.
Available Video Demonstrations include:
Snowball dev board running Linaro's build of Android ICS with hardware
acceleration:

Android ICS (with 3D demo)
http://www.youtube.com/watch?v=7_MCLKmXDFA&feature=youtu.be
In addition to these highlights and improvements delivered by Linaro
engineers, the following updates and features are also available:
The Android Team continues to focus on Ice Cream Sandwich (ICS) and delivers
Linaro Android ICS built with the Linaro toolchain and running on all our
supported hardware. Other enhancements for ICS are DS-5 with Gator and
libjpeg-turbo support. Development of AOSP continues with a Linaro AOSP master
build now available.
The Development Platform Team delivers high quality improvements and features
which consist of the linux-linaro and lt-panda kernel packages, now
automatically generated by the CI build scripts. Other achievements from this
team include: UCM support is enabled in PulseAudio, integrated in our images
and works out of the box on i.MX53/PandaBoard boards. The preview images for
Ubuntu 12.04, Precise Pangolin are available and include nano, developer,
server, alip (Xfce desktop based), and ubuntu-desktop. The Ubuntu LEB now
includes debug packages (ddeb) for all Linaro-specific packages, which can be
downloaded from the Linaro Overlay PPA.
The Multimedia Team updates introduce the realvideo codec implementation in
libav, with NEON optimisations and Speex for Android which includes the NEON
optimisation patches. The team also addsupdates to the pulseaudio ucm branch,
alsa-lib ucm patches and includes alsa-ucm-pa tests to verify that the
pulseaudio ucm works as expected. Additionally, the Multimedia Team also
announces a prototype application for unattended end-to-end testing of the
audio stack for Ubuntu which works for Intel/Ubuntu and are available from:
http://git.linaro.org/gitweb?p=people/kurt-r-taylor/e2eaudiotest.git
Memory management updates include the development of dri2proto, updates to
libdri2 which support dri2video and dri2video test app, updates to mesa and
implementation of the core functionality in xserver against xf86-video-nouveau
and xf86-video-omap. Trace events and debugfs support for CMA and made CMA
testing available for Snowball boards in LAVA are also found in this release.
The multimedia contributed code for memory management are also available (as
topic branches) from
git://git.linaro.org/people/jessebarker/linaro-mm-sig/linux.git
The Infrastructure Team is supporting the ongoing effort for Linaro as a
whole. The reworking of the Linaro roadmap under
http://status.linaro.org/11.12/roadmap-2011Q4.html
now includes artistic graphs that visualize work items progress for roadmap
goals. The Linaro build services can contain vendor-provided binary overlays
for hardware acceleration and are published in a way which requires click
through license acceptance before being downloaded. Click through license
acceptance has also been added to Android builds which use source overlays
from snapshots.linaro.org.
The Toolchain Working Group (WG) efforts this cycle show that the Linaro GCC
now includes support for 64 bit sync primitives, unaligned block moves on
ARMv7, and backports the Cortex-A15 pipeline description from the ongoing
upstream A15 work. Improvements to the vectorizer include updates to the
straight line vectorizer, including supporting operations with an arbitrary
number of operands, vectorizing conditions, and improved pattern recognition
support. Additionally, GDB now supports single stepping over atomic operations
and QEMU has been rebased on the new upstream 1.0 release.
The Validation Team lands the support of Samsung Origen boards on LAVA. The
boards are now available to run daily tests. In addition, the i.MX53 Quick
Start support improvements include the ability to deploy Android images and
run the Kernel CI testing. To streamline the deployment of LAVA and allow for
a more continuous testing and flexible deployment process, a new tool is
introduced: lava-deployment-tool.
The Graphics Team accomplishments in this release are numerous and include the
implementation of a GLMark2 benchmark for performing bilinear filtering
manually in shaders that are used to smooth textures when displayed larger or
smaller than their actual size. Other accomplishments include added support
for glproxy in glcompbench which allows choosing the backend (OpenGL or OpenGL
ES2) at runtime instead of building a different executable for each, EGL
virtualization support to glproxy, enabling it to virtualize EGL as it does
GLX, so applications can decide on using one or the other at run-time,
depending on availability. GLCompbench now shares some neat GLMark2 objects
for managing GLSL (and GLSL ES) shader source prior to compilation and
linking. These inclusions can be seen as a preprocessor for the strings read
out of the files on disk and allow for dynamic generation of precision
declarations, constants, and other symbols (or even whole sections of code) at
either global or local scope. Objects shared from GLMark2 include: Util,
ShaderSource, and the CompositeTestBase update to use ShaderSource. Also
updated shaders to useShaderSource, and derived GL-based test classes to
configure shaders. Additionally the Team enabled apitrace, which provides a
tracer and retracer executable, to work on systems having only EGL/GLES2
libraries.
The Power Management Team pushed a number of items upstream. Items include:
common clock patches v4 which includes support for OMAP4, version 2 of common
ARM and i.MX cpuidle driver, a patch for non ACPI based generic processor
cooling devices, and a patch for a new trip type needed for cooling devices
like cpufreq. The Team also integrated sched_mc for ARM into Linaro Kernel,
and for thermal management tested that temperature is reduced in production
using the current solution on Origen board.

issues, can be found on the release pages of our Wiki.

Today we are announcing the new Linaro Community Contributor process[0] and
team[1].
Linaro itself is now an organisation of around 120 engineers, but as we
continue to grow the community around us is also growing fast. We're
grateful to the many people who are participating in our success, and so
we're introducing the Community Contributor process to recognise those
community members who have sustained contributions over a significant
period of time. Our Technical Leads now have the opportunity to nominate an
individual as a Community Contributor of Linaro. The benefits of becoming a
Community Contributor will include:
* a Linaro e-mail address
* the right to carry Linaro business cards (we supply the artwork, you
print your own cards)
* a Linaro IRC cloak
* listing in the relevant Working Group on our Linaro organisation structure
* listing in the Launchpad Community Contributors Team
Applying to be a Linaro Community Contributor is an easy process.
Community members can apply by requesting a nomination from a Linaro
Technical Lead (alternately, the Technical Lead may approach them about the
application).
After that they will need to complete and sign our Community Contributor
Agreement[2].
The main points are that the community contributor agrees to are:
* to our e-mail terms of use, including use of your Linaro e-mail for
upstream contributions
* a copyright and patent licence to Linaro for any code you contribute with
that e-mail address
Once that's done, the Technical Lead submits the nomination and completed
Agreement to our Community Board [3]. The nomination will normally describe
how the community member has worked with Linaro, any Blueprints they may
have been involved with and Linaro Connect events they may have attended.
The Community Board will then evaluate all nominations within 2 weeks of
submission and all being well the community member will be welcomed as a
Community Contributor. We currently have nominations and signed agreements
filtering in so this is an exciting time for all of us.
We place a lot of value on having a vibrant network of Community
Contributors, so this does mean we reserve the right to cancel an
appointment at any time if we feel the Contributor is not active in using
the above benefits.
To find out more about the Linaro community and how to participate please
see our community section [4] of linaro.org [5]
Please feel free to email the Community Board [6] if you have questions or
wish to submit a community member for consideration.

The Linaro Toolchain Working Group is pleased to announce the
release of Linaro QEMU 2011.12.
Linaro QEMU 2011.12 is the latest monthly release of
qemu-linaro. Based off upstream (trunk) QEMU, it includes a
number of ARM-focused bug fixes and enhancements.
New in this month's release:
- There are no Linaro-specific changes of note in this release
- This release is based on the upstream QEMU 1.0 release.
(Note that future qemu-linaro releases will continue to track
upstream trunk; the release dates for upstream and our
release just happened to be conveniently aligned in this case.)
Known issues:
- Graphics do not work for OMAP3 based models (beagle, overo)
with 11.10 Linaro images.
- This release of qemu-linaro is known not to work on ARM hosts.
(See bugs #883133, #883136)

The Linaro Team is pleased to announce the release of Linaro 11.11, another
of Linaro’s releases delivered on a monthly cadence.This release includes
components delivered by all Linaro Teams: Working Groups, Landing Teams and
Platform Teams. Some outstanding effort has gone into delivering a lot
of exciting updates and features integrated on top of Android and Ubuntu.
Up to now, this reads like a normal monthly release announcement, but wasn’t
there something special??? Yes!
We had Android Ice Cream Sandwich for the world this month and the Android
Team worked hard to deliver a sneak preview of early alpha ICS images for our 4
primary development targets!
The Release Team notes that this is a remarkable achievement and congratulates
the Linaro Android Team for this effort that showed how agile that
team is set up
to accommodate engineering plan mid-month and get these builds up and out
within 10 days. Check out our ICS running on Snowball. Video available on
youtube: http://www.youtube.com/watch?v=MQOKPLg3ARE.
If you don’t want to read the rest of this announcement but want to
get started on our ICS builds, please go to our download mirror directly,
download the bits and follow our easy install instructions that you
will find there:
http://releases.linaro.org/11.11/android/images-ics-preview
Obviously, Linaro continued to deliver great stuff outside of those Android ICS
builds. So here are the big items that the Release Team has selected to feature
this time:
The Android rockstars delivered ICS preview builds but did not detour from their
initially stated release goals. Among them we have an upgraded Android LEB
based off Android 2.3.7 that comes again with all optimizations and
bleeding edge Linaro toolchain integration. Other Android builds
showcase a first
release for Versatile Express using the Linaro ARM LT kernel, a NEON optimized
libpng, preliminary DS-5 support and a host of bug fixes and enhancement's to
existing support.
The Linaro Ubuntu LEB now supports officially the PandaBoard ES and features
PandaBoard's USB booting with U-Boot USB-SPL. The developer story was
improved with updated ARM DS-5 packages. Source and debug packages for all
Linaro's kernel flavors are now available. Additionally, Firefox can now be
cross-built using multi-arch. Instructions are available from
http://wiki.linaro.org/Platform/DevPlatform/CrossCompile/FirefoxCrossCompile.
The Infrastructure Team rolled out our new git mirroring approach to
our android cloud build service that uses a seed approach. With that, we noticed
considerable speedup in total build time for android builds as well as
a massive
improvement with regard to scalability as the load put on git-daemons that can
be quite inefficient is minimized due to this improvement. On top
Infrastructure
released an update to status.linaro.org that connects engineering with roadmap
planning using the well known status.linaro.org approach.
The Graphics team has added a new benchmark for bump-mapping for glmark2.
Bump-mapping is a technique for simulating bumps and wrinkles on the surface of
an object. This improvement is coming along side LAVA test cases that improve
glmark2 support for automated testing and in particular support
bump-mapping now.
Linux Linaro 3.1-2011.11 release includes a fresh rebase of Linaro
improvements to the v3.1.1 mainline kernel and features LPAE support,
Samsung Exynos cpuidle,sched_mc optimization, and a fix for mmap
greater than 2GB. The Kernel WG has also enabled eCryptFS in Linaro and
Android kernel defconfigs.
Some highlights for the Multimedia team are that Speex was released on Linaro
Ubuntu evaluation build with NEON optimisation patches, libpng v1.5
was released with additional patches to allow NEON auto-detection, and
libjpeg-turbo is now built with compatibility for libjpeg8.
The Validation Team started to land the new LAVA user interface and navigation,
with a shiny Linaro theme. Under the hood, LAVA infrastructure has been
upgraded, including network improvements and more memory to better serve its
increasing users base.
Full details of this release, including detailed release highlights
and known issues, can be found on the release pages of our Wiki.
We encourage everybody to use the 11.11 release. The download links for all
images and components are available on our downloads page:

Linaro 11.10 are available here:
Android: http://wiki.linaro.org/Cycles/1111/BoardSupport/Android
Ubuntu: http://wiki.linaro.org/Cycles/1111/BoardSupport/Ubuntu
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:
http://wiki.linaro.org/Platform/DevPlatform/Ubuntu/ImageInstallation

The Linaro Toolchain Working Group is pleased to announce the
release of Linaro QEMU 2011.11.
Linaro QEMU 2011.11 is the latest monthly release of
qemu-linaro. Based off upstream (trunk) QEMU, it includes a
number of ARM-focused bug fixes and enhancements.
New in this month's release:
- The ARM vexpress-a9, versatilepb, versatileab and realview-*
boards now have audio support (thanks to Mathieu Sonet who
contributed a PL041 implementation upstream)
- Support for multiple instances of the "-sd" option on the
command line has been dropped; this was never present in
upstream QEMU and has been removed for consistency. Use
"-drive,if=sd,index=N,file=file.img" for N=0,1,2... instead
- Fixes #886980: 8 and 16 bit reads from the OMAP GPIO module
would crash due to an infinite recursion
- Fixes #823902: problems running multithreaded programs in
linux-user mode
Known issues:
- Graphics do not work for OMAP3 based models (beagle, overo)
with 11.10 Linaro images.
NB: if you run QEMU on a host system without properly configured
audio you might find that QEMU now hangs at some point; you can
fix this by fixing your host system, or work around it by setting
the environment variable QEMU_AUDIO_DRV=none.
If you build from source you may now want to pass configure
a suitable --audio-drv-list=LIST option.
The source tarball is available at:
https://launchpad.net/qemu-linaro/+milestone/2011.11
Binary builds of this qemu-linaro release are being prepared and
will be available shortly for users of Ubuntu. Packages will be in
the linaro-maintainers tools ppa:
