We are pleased to announce the release of Linaro 12.02.
If I have seen further than others, it is by standing upon the shoulders of giants.
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:
- 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
- Linaro Connect: Patrik Klinger Talks Snowball & The Igloo Community
- Tim Bird and David Rusling Chat at Linaro Connect

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 provide pre-built versions of Linaro GCC and Linaro GDB that target either a Linaro Evaluation Build or a bare-metal target.
More interested in bare-metal and long-term maintained releases for ARM embedded processors? We're working with ARM to also supply a Cortex-R and Cortex-M bare-metal build. Major releases will be made once a year with quarterly update releases. Releases will be maintained for two years.
