The Linaro Team is pleased to announce the release of Linaro 11.09,
the Linaro’s fourth release delivered on a monthly cadence.
This release includes components delivered by all Linaro Teams: Working Groups,
Landing Teams and Platform Teams. As usual, it brings a lot of updates and new
features, integrated on top of Android and Ubuntu.
Among the improvements brought by this release and delivered by Linaro
engineers, it worths mentioning:
* Beta release of our Continuous Integration (CI) Build Service focused on
continuous large scale kernel tracking. This is a first step in support of
the new Kernel Working Group developement model based on a stable tree and
continuous integration of the Working Groups and Landing Teams Kernel.
* Ubuntu based image distribution format has seen a big improvement through
the arrival of hardware packs v2. This new format will allow more flexibly
in shipping our growing board support alongside our hardware independent
Ubuntu based images.
* On the hardware enablement front, both Android and Ubuntu images have seen
good improvements on most of our primary target boards. This includes the
availability of Wi-Fi and Bluetooth for Android PandaBoard builds and audio
(ALSA UCM) on our Ubuntu builds with proper kernel support.
* Android image builds are first to incorporate the whole userspace and kernel
using the Toolchain Working Group proposed -O3 option.
* The Graphics Working Group added a xrender based compositing test to
GLCompBench and merged a 2D convolution benchmarking scene and 3D
screensaver inspired benchmarking scene to GLMark2. With these improvements,
our set of graphics tests grows again by tests designed with real user
experience use cases. In addition, GLMark2 is now integrated on all our
Android builds and is automatically run in Linaro Validation Farm.
* The Kernel Working Group continued their outstanding work to always make the
very latest available ARM bits included as part of our linux-linaro 3.0.4
based release. We include the ARM merged code of 3.1-rc1 from Russell King's
tree, stable and ready for consumption.
* LAVA saw various plumbing improvements. The number of PandaBoards deployed
got a significant boost with roughly 15 boards now being active 24/7.
* Last but not least, we have the usual updates of our core components from
the Toolchain Working Group, including a fresh code drop for gcc-linaro,
gdb-linaro and qemu-linaro. All those of course come pre-integrated for
direct use on Ubuntu host as well as Android or Ubuntu targets.
We encourage everybody to use the 11.09 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:

The Linaro Toolchain Working Group is pleased to announce the release
of Linaro QEMU 2011.09.
Linaro QEMU 2011.09 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:
- linux-user mode now supports the 64 bit cmpxchg kernel helpers
(only needed for applications compiled for ARMv6 or lower)

where BGR was interpreted as RGB on recent versatilepb kernels
Plus a few other minor bug fixes and the usual round of upstream
fixes and improvements.
Known issues:
- The beagle and beaglexm models still do not support USB networking;
we intend to fix this for the 2011.10 release
