We are pleased to announce the release of Linaro 12.02.
Linaro 12.02 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.
During the 12.02 cycle, Linaro hosted its Linaro Connect Q1.12 in Redwood City,
California on 6-10 February. Many Linaro Team members also participated in
the 2nd Annual Android Builders Summit on 13-14 February and the Embedded Linux
Conference on 15-17 February also held in Redwood City, California and hosted
by the Linux Foundation.
During the Linaro Connect event there were daily plenary, planning, and hacking
sessions which attendees were encouraged to attend and take part in. This event
also marked the first time which Google+ Hangouts were used during a Connect
event to encourage remote participation from those developers around the globe.
Also, held during this Connect event was the ever growing Demo Friday event
where Linaro, its community, partners and members came together and
demonstrated the agile development process which is highlighted monthly in each
of our releases.
Highlights from this Linaro Connect event which influence this and future
releases include:
* Plenary Sessions:
* David Rusling, Linaro CTO, Phase III Plenary Presentation at
Linaro Connect Q1.12
* George Grey, Linaro CEO, Plenary Presentation at Linaro Connect Q1.12
* Kiko, Linaro Engineering VP: ARM, the new mainstream
* Linaro Connect Plenary: Andrea Gallo of ST-ERICSSON
* Tim Bird of the Linux Foundation at Linaro Connect
* Interviews:
* Linaro Connect: Patrik Klinger Talks Snowball & The Igloo Community
* Tim Bird and David Rusling Chat at Linaro Connect
* Demos:
* Ubuntu TV Demo on ARM
* XBMC on ST-ERICSSON's Snowball
Other video from Linaro can be found on the Linaro Youtube channel.
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.
We encourage everybody to use the 12.02 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:
http://wiki.linaro.org/Platform/DevPlatform/Ubuntu/ImageInstallation
