Unity is strength... when there is teamwork and collaboration, wonderful
things can be achieved.
~Mattie Stepanek
The Linaro 13.04 release is now available for download!
The 13.04 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 13.04 release cycle has been one of the busiest and most productive
cycles to date. There were 7 individual team releases during this cycle
all of which help build the foundation of the Linaro 13.04 release.
It is through the teamwork and collaboration between Linaro, its members
and community that the achievements of each are unified in these monthly
releases and continue to build the future of Linux on ARM.
Quality builds continue to be the foundation on which the future of Linux
on ARM is being built, this quality is ensured through our testing and
validation teams. Fedora support has been merged in LAVA and users can
now submit LAVA jobs using a Fedora pre-built image. The QA Team
announced that tests to cover big.LITTLE cluster init and shutdown have
been added to the big.LITTLE core test suite and big.LITTLE extended test
case scenarios have been implemented.
Our Builds and Baselines teams are the footers that support this
foundation of collaboration and during the 13.04 release front, Dalvik VM
unit test has now been automated and the native toolchain on Android has
been updated to Linaro GCC 4.8. The Android tree has been updated to
compile with GCC 4.8 based toolchains and all related changes have been
upstreamed. The ARMv7 KVM enabled kernels intergrated into our pre-built
images are now built daily and tested in Linaro's CI loop.
The OpenEmbedded ARMv8 engineering build now provides 64bit HipHop VM
requirements for porting and optimization purposes. The OpenEmbedded test
cases have been automated and a current list of these tests can be found
at: https://git.linaro.org/gitweb?p=qa/test-definitions.git;a=tree;f=openembedded
The Linaro Kernel WG focused on the following areas during this release
cycle: refactor EHCI controller code, depopulate Exynos/ux500/plat-nomadik,
expand binder unit test, improve eMMC power management support, port some
of the platforms to multi-platform support, Android upstreaming effort,
and much more.
Additional highlights include the release of a big.LITTLE porting guide
by the Power Management WG and Linaro GCC 4.8 by the Linaro Toolchain WG.
We encourage everybody to use the 13.04 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/GetSource
http://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
