Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2.
This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available.
Here are the highlights of this release:
- Automation and Validation
- A simple CLI tool for communicating with the CI dashboard has been developed
- LAVA supports Arndale booting with UEFI. The bootloader configuration is done on the fly
- Snowballs coming back online
- Builds and Baselines
- linux-linaro-arndale Bringup with Tiny Android build for Arndale setup, and Android with GUI planned for the next cycle.
- Origen-Quad Member build
- Native Toolchain on Android
- The toolchain is now available natively inside Linaro Android builds.
- The builds now include gcc, g++, vim, make, a terminal emulator and a vi-friendly keyboard.
- Unified manifest – Details on how to work with common manifest can be found on https://wiki.linaro.org/Platform/Android/WorkWithCommonManifest
- Restructure release toolchain – Released toolchains are checked into a prebuilts/ git repository and pulled in by the manifest as opposed to being downloaded as separate tarballs.This is the approach taken by AOSP to distribute the toolchain.
- CTS Support in LAVA
- CTS support for 4.2 reworked for better stability.
- CTS has been enabled for the Engineering builds.
- Investigations to be done next cycle on tests that are not getting executed.

- Toolchain
- Linaro GCC 4.7 2013.03 released, based off the latest GCC 4.7.2+svn195745 release
- Linaro GCC 4.6 2013.03 released, based off the latest GCC 4.6.3+svn196247 release
- Linaro QEMU 2013.03 released, based off upstream (trunk) QEMU. This release has been updated to be based on upstream’s recent 1.4.0 release. It also includes ARM KVM support patches which are in sync with the ABI as committed to the upstream Linux kernel for 3.9. This feature is still under development but will no longer be subject to kernel-vs-userspace ABI breaks.
