Linaro 11.11 Released

Home / Linaro Blog / Linaro 11.11 Released

The Linaro Team is pleased to announce the release of Linaro 11.11, another of Linaro’s releases delivered on a monthly cadence.This release includes components delivered by all Linaro Teams: Working Groups, Landing Teams and Platform Teams. Some outstanding effort has gone into delivering a lot of exciting updates and features integrated on top of Android and Ubuntu.

Up to now, this reads like a normal monthly release announcement, but wasn’t there something special??? Yes!

We had Android Ice Cream Sandwich for the world this month and the Android Team worked hard to deliver a sneak preview of early alpha ICS images for our 4 primary development targets!

The Release Team notes that this is a remarkable achievement and congratulates the Linaro Android Team for this effort that showed how agile that team is set up to accommodate engineering plan mid-month and get these builds up and out within 10 days. Check out our ICS running on Snowball. Video available on youtube: http://www.youtube.com/watch?v=MQOKPLg3ARE.

Obviously, Linaro continued to deliver great stuff outside of those Android ICS builds. So here are the big items that the Release Team has selected to feature this time:

  • The Android rockstars delivered ICS preview builds but did not detour from their initially stated release goals. Among them we have an upgraded Android LEB based off Android 2.3.7 that comes again with all optimizations and bleeding edge Linaro toolchain integration. Other Android builds showcase a first release for Versatile Express using the Linaro ARM LT kernel, a NEON optimized libpng, preliminary DS-5 support and a host of bug fixes and enhancement’s to existing support.
  • The Linaro Ubuntu LEB now supports officially the PandaBoard ES and features PandaBoard’s USB booting with U-Boot USB-SPL. The developer story was improved with updated ARM DS-5 packages. Source and debug packages for all Linaro’s kernel flavors are now available. Additionally, Firefox can now be cross-built using multi-arch. Instructions are available from http://wiki.linaro.org/Platform/DevPlatform/CrossCompile/FirefoxCrossCompile.
  • The Infrastructure Team rolled out our new git mirroring approach to our android cloud build service that uses a seed approach. With that, we noticed considerable speedup in total build time for android builds as well as a massive improvement with regard to scalability as the load put on git-daemons that can be quite inefficient is minimized due to this improvement. On top Infrastructure released an update to status.linaro.org that connects engineering with roadmap planning using the well known status.linaro.org approach.
  • The Graphics team has added a new benchmark for bump-mapping for glmark2. Bump-mapping is a technique for simulating bumps and wrinkles on the surface of an object. This improvement is coming along side LAVA test cases that improve glmark2 support for automated testing and in particular support bump-mapping now.
  • Linux Linaro 3.1-2011.11 release includes a fresh rebase of Linaro improvements to the v3.1.1 mainline kernel and features LPAE support, Samsung Exynos cpuidle, sched_mc optimization, and a fix for mmap greater than 2GB. The Kernel WG has also enabled eCryptFS in Linaro and Android kernel defconfigs.
  • Some highlights for the Multimedia team are that Speex was released on Linaro Ubuntu evaluation build with NEON optimisation patches, libpng v1.5 was released with additional patches to allow NEON auto-detection, and libjpeg-turbo is now built with compatibility for libjpeg8.
  • The Validation Team started to land the new LAVA user interface and navigation, with a shiny Linaro theme. Under the hood, LAVA infrastructure has been upgraded, including network improvements and more memory to better serve its increasing users base.

For better support and tracking the hardware sanity of our supported boards, we now publish a board support status with each monthly release. The results for Linaro 11.10 are available here:

Android: http://wiki.linaro.org/Cycles/1111/BoardSupport/Android
Ubuntu: http://wiki.linaro.org/Cycles/1111/BoardSupport/Ubuntu

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
