Linaro 13.04 Released


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:

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. To find out more about the highlights and a more detailed list of the updates, fixes, and features that were added this cycle please see the release notes.

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:

If you are interested in getting the source and building these images yourself please see the following pages:


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:
