| h2. About the Linaro Confectionary Release for Versatile Express (Aarch32) |
| |
| The Linaro Confectionary release is based on the AOSP Lollipop |
| Android-5.1.1_r1 version. This reference build is a userdebug variant |
| build, and it contains support allowing full use of the 32-bit ARMv7-A |
| architecture and supports the 32-bit applications, with SELinux |
| enabled by default. |
| |
| The release uses the Linaro Stable Kernel version 3.10. The sources are |
| built using Linaro GCC 4.9-2015.04. To disable SELinux pass "selinux=0" |
| as the boot parameter in the UEFI bootargs configuration. |
| |
| The Android AOSP software provided in this release is functionally |
| tested with CTS version 5.0 R2 and the CTS results are shared with |
| members. The BIONIC component is additionally validated with Android |
| BIONIC tests. Android Monkey tests were run for stress testing. We also |
| added some benchmark tests to observe the performance trend in various |
| fields. |
| |
| Sources are also made available so you can build your own images |
| (see the "Building from Source tab":http://releases.linaro.org/15.04/android/vexpress-lcr#tabs-2). |
| |

| * Toolchain switched to Linaro GCC 4.9-2015.04, Linaro Binutils 2.25.0-2015.01-2 |
| |
| h2. About the Android flavour of Linaro Stable Kernel (LSK) |
| |
| The kernel used by Linaro Confectionary Release for Versatile Express |
| is the Android flavour Linaro Stable Kernel (LSK), which is produced, |
| validated and released by Linaro and is based on the Linux stable |
| kernel tree. |
| The LSK focuses on quality and stability and is therefore a great |
| foundation for product development. It also includes backports of |
| commonly desired features, provided they meet the quality requirements, |
| and also any bug fixes. |
| |
| Sources are also made available so you can build your own images (see |
