Release Information

β€œAll things are created twice; first mentally; then physically. The key to creativity is to begin with the end in mind, with a vision and a blue print of the desired result.” ~Stephen Covey

We are pleased to announce the release of Linaro 13.01.

With the first release of the calendar year, Linaro is happy to highlight the ingredients that make up the deliverables, again produced by Linaro Teams – Working Groups, Enterprise Group, Landing Teams and Platform Teams –. Linaro anticipates another great year of Linux on ARM development celebrating new members and producing some cutting edge advances.

The Developer Platform Team has enabled 64bit HipHop VM development in OpenEmbedded, continued to merge ARMv8 support into the OpenEmbedded platform and upstream, engaged initial support for the Arndale board and released Linux Linaro 3.8-rc4 2013.01.

For the Android team, it was a busy cycle. The initial changes to android-build page for the new build program have been done. They are finally moving towards consolidation of manifests: Origen and Versatile Express can now be synced and built from the same manifest. The Team is happy to announce linaro-android-tools which is directed towards kernel developers. The tool can be used to update kernel and initrd in Android without having to remove the SDcard. They have also updated the third party benchmarks to use the uiatomator testing framework introduced in Jelly Bean. Android hardware pack support has been added.

The first stable Juice builds have been created and integrated into Linaro's automated testing infrastructure LAVA. The builds allow early Android development to begin on upcoming ARMv8 Models. The builds have been tested against 40 manual and 60 automated tests that cover all aspects of the platform including core Android feature testing and platform use.

The Linaro Enterprise Group (LEG) has released Linaro UEFI 2013.01. The highlights include fixes for native building of UEFI on ARM platforms and improvements to flashing images on Arndale board and enable native building for PandaBoard.

The Power Management Group hosted a big.LITTLE sprint in Cambridge led by Amit Kucheria. A meeting of minds between ARM, Linaro and the community succeeded in achieving enhanced focus and a more defined roadmap for the big.LITTLE story. Topics included clearly defined benchmarking to determine the effectiveness of the platform, enhanced verification to augment the traditional kernel power/performance testing, and a well defined roadmap for big.LITTLE on Android. In related big.LITTLE MP development, version 14 of the big.LITTLE MP tree has been released.

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:
