Linaro 12.06 Release with Kernel 3.5 and Android 4.0.4

Linaro has released version 12.06 based on Linux Kernel 3.5-rc3 and Android 4.0.4 (r2.1).

This release brings further multimedia enablement for Android as well as some improvement to perf for Android, improved instructions & scripts for multi-arch on Ubuntu, and lots of little improvements and bugs fixes.

Here are the highlights of the release:

  • Android
    • Multimedia enablement on AOSP, patches are in review.
    • Most of the benchmarking applications have been automated via Monkeyrunner, working on PandaBoard and Snowball.
    • Update panda-ics-gcc47-tilt-tracking-blob build to the TI LT 3.4 kernel.
    • USB camera preview and still capture forward ported to tilt-tracking.
    • 3D graphics and multimedia working on tilt-stable.
    • IOMMU for Origen’s Multi format codec (MFC) enabled.
    • IOMMU for Origen’s FIMC enabled. (FIMC stands for Fully Interactive Mobile Camera, and it’s used for camera input).
    • Snowball upgraded to Android 4.0.4.
    • Cortex strings landed in Linaro Android and submitted to AOSP (https://android-review.googlesource.com/#/c/38031/). This is part of the Android optimizations discussed here.
    • Linaro Android updated to Android 4.0.4 r2.1.
    • Linaro Android panda-ics-gcc47-tilt-stable-blob build graphics acceleration upgraded with 4.0.4 binaries from AOSP.
    • perf for Android in PandaBoard, patches submitted to Linaro kernel maintainers for other boards and lkml (http://patches.linaro.org/9603/)
    • Worked around PandaBoard graphics issue (Panda crashes after 10 min, https://bugs.launchpad.net/bugs/912651) by using a lower resolution.
  • Developer Platform
    • Kernel config fragments are now used by all the kernel packages available in the Linaro Evalution Builds, including one single fragment for the Ubuntu specific configs, which now allows all builds to behave similarly.
    • Pre-built images validation was improved for the supported Linaro Evaluation Builds flavors, including a html file that describe the image content, and displays the test results from LAVA.
    • Fixes for wifi-enablement, bluetooth-enablement, leb-basic-graphics and perf test cases. They should now be properly reflecting the Linaro Evaluation Builds images results.
    • Kernel packages updated to the latest development trees from Linux Linaro and Landing Teams.
    • A new Linux Linaro branch, called Linux Linaro Tracking, is now published. It contains the 3.4 Landing Team trees from TI, Samsung and ARM, delivering a single and unified tree which helps identifying conflicts and issues ahead of upstream.
    • Linux Linaro maintenance scripts are now available on http://git.linaro.org/gitweb?p=people/ynk/ll-tools.git;a=summary repository.
    • Improved instructions and scripts to easily cross-build a package using multi-arch with Ubuntu, available on https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/UsingMultiArch
  • Infrastructure
    • Engineering views are now available for consumption by Linaro engineers and managers in Launchpad directly. e.g. https://launchpad.net/~linaro-infrastructure/+upcomingwork
    • We are now in the process of using custom AMIs (Amazon Machine Images) preloaded with build dependencies for faster builds on android-build.linaro.org and ci.linaro.org services.
    • Publishing improvements to infrastructure include: builds with license-protected binary blobs and builds with restricted access (OpenID-based)
    • Bug fixes and improvements made to patches.linaro.org (now functioning) and to linaro-image-tools.
  • Graphics
    • Added 2 new features to GLMmark2: running in fullscreen mode and some additional per-frame statistics (average time per frame rather than just the frames per second).
    • On the Graphics WG dashboard, multiple data series (for example from different sessions like Ubuntu/plain X/Android) can be displayed in the graphs.
  • Multimedia
    • The gathering of 5.1 and 7.1 test audio files now complete.
    • UCM support on PulseAudio 2.0 updated.
    • Libjpeg-turbo updated to 1.2.1+svn837.
  • Power Management
    • PowertTOP 2.0 made to work on ARM platforms
      • Patches sent upstream (in review).
      • package available in LInaro Ubuntu.
      • Work in progress on Android.
