It' s easy to get good players. Getting them to play together,
that's the hard part. ~Casey Stengel
The Linaro 13.07 release is now available for download!
The 13.07 Linaro release highlights the collaborative 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,
OpenEmbedded and Ubuntu baselines during this development cycle.
With this release we are reminded of the great "players" who come together to
plan and create the future of Linux on ARM. Seeing the synergic efforts of
Linaro, its members and the greater Open Source Community is what drives our
future--the future of Linux on ARM.
On the Builds and Baselines front, the Linaro Stable Kernel preview 2013.07 was
updated: based on the 3.10.1 stable kernel tree; including ARM MP patch set,
IKS VExpress TC2 and Power efficient workqueue support, Android v3.10
experimental patch set from AOSP. Linaro OpenEmbedded baseline added
libjpeg-turbo as the preferred provider for jpeg, updated to the Linaro GCC
4.8-2013.07 release and switched builds to use Linaro versions of binutils and
eglibc (2.17). Linaro Android baseline reports that the Arndale platform has
been updated with display support on HDMI using software graphics stack,
and is built with the Linaro GCC 4.8-2013.07 release as well.
The Linaro toolchain Working Group released Linaro GCC 4.8 and 4.7 2013.07
which added address Sanitizer support for ARM along with the new -mrestrict-it
option support. The backports of support for further AArch64 aand ARMv8 AArch32
instructions were added. Linaro eglibc 2.17-2013.07 has optimized string
functions for AArch64: memcmp, memset, memcpy, memmove, bzero, strcmp, strlen,
strnlen, strncmp.
As of this release, the Linaro LAVA lab now hosts 75 devices including 4 new
member systems and an actual “LMP stack” which is a tower of 5 LAVA
Multi-purpose Probe boards (including SDMux support) is now being prototyped
and tested. Multi-node test is currently in beta, but a live demo from LCE13
can be seen at: http://multinode.validation.linaro.org sandbox.
Advanced LAVA configuration options were reviewed during this cycle and topics
that were discussed included managing a multi-machine (LAVA Servers & worker
nodes), deployment with salt-stack (LAVA Cambridge Lab), generic test
integration, creating a test parser, overriding boot commands and the new
interactive boot command support in LAVA.
We encourage everybody to use the 13.07 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:

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 OpenEmbedded-based images
=======================
With the Linaro provided downloads and with ARM’s Fast Models virtual platform,
you can boot a virtual ARMv8 system and run 64-bit binaries.
For more information please see:
http://www.linaro.org/engineering/armv8
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
