About the Linaro Android Release for Juno (32-bit only) - -The Linaro Android release is based on a snapshot of the Android AOSP master taken on the 1st June. The build demonstrates the native 32-bit support found in the ARMv8-A architecture. The release uses Linaro Stable Kernel version 3.10 and is integrated with ARM Mali drivers for 3D graphics acceleration. The sources are built using Linaro GCC version 4.9. - -The Android AOSP software provided in this release is thoroughly tested with CTS version 4.4 and the CTS results are shared with members. The BIONIC component is validated with Android BIONIC tests. Android Monkey tests were run for stress testing. - -*NOTE:* The default setting from AOSP Build Variant "Engineering" is not performant for applications with ART. For better performance follow the instructions below: - -* The default build scripts (linaro_android_build_cmds.sh) included in this release, builds the Android sources for “TARGET_BUILD_VARIANT=eng”, this in turn sets the compiler-filter option in dalvik.vm.dex2oat-flags to “interpret-only” mode (refer build/core/main.mk). - -* If the user is interested in performance of apps we suggest re-building the sources for “user” mode instead of “eng” mode. To do this, in the script file linaro_android_build_cmds.sh, please modify the line number 153 by replacing “eng” with “user” and then run the script. - - -The Linaro Android releases for Juno (32-bit) appear monthly. Sources are also made available so you can build your own images (see the Building from Source tab). - -h2. About the Juno ARM Development Platform - -The Juno ARM Development Platform (ADP) is a software development platform for ARMv8-A. It includes: -* The Juno Versatile Express board -* ARMv8-A reference software ports available through Linaro -* Optional LogicTile Express FPGA board to extend the Juno system - this adds a large FPGA to Juno that can be used for driver development or prototyping. - -The Juno hardware delivers to software developers an open, vendor neutral ARMv8-A development platform with: -* Cortex® A57 and A53 MPCore™ for ARMv8-A big.LITTLE -* Mali™-T624 for 3D Graphics Acceleration and GP-GPU compute -* A SoC architecture aligned with Level 1 (Server) Base System Architecture - -The Juno ADP is available from ARM, please visit "www.arm.com/juno":http://www.arm.com/juno in early July for more details. - -h2. About the Linaro Stable Kernel (LSK) - -The Linaro Stable Kernel (LSK) 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. - -LSK releases appear monthly. Sources are also made available so you can build your own images (see the "'Building from Source'":https://releases.linaro.org/14.06/android/images/armv8-juice-juno-lsk/#tabs-3 tab). - -h2. License - -The use of Juno software is subject to the terms of the Juno "End User License Agreement":https://releases.linaro.org/14.06/android/images/armv8-juice-juno-lsk/#tabs-5. - -h2. Support - -Please send any ARM support enquiries to "juno-support@arm.com":mailto:juno-support@arm.com?subject=Juno%20support%20request. Engineers at Linaro Members can receive support for Juno by sending support requests to "support@linaro.org":mailto:support@linaro.org?subject=Juno%20support%20request or visiting "http://support.linaro.org":http://support.linaro.org. - -h2. Functionality Listed by Software Component - -h3. AOSP Filesystem - -* Snapshot of the AOSP Master at 1st of June 2014 -* ART Runtime enabled as default and booting in 64-bit primary mode -* GPU support.

UEFI - -* Booting an Operating System from NOR Flash or USB mass storage -* Support for Ethernet and PXE boot -* Version: v1.0-rc0 - -h3. ARM Trusted Firmware - -* The ARM Trusted Firmware provides an open source framework enabling easy integration of secure OS and run-time services to ARMv8-A platforms -* Loads the System Control Processor(SCP) firmware into the SCP -* Initializes the Trusted World before transitioning into Normal World. -* Services CPU hotplug requests coming from Normal World -* Provides a standard Power State Coordintion Interface (PSCI) implementation -* Version: v0.4-Juno-0.5-rc1 - -h3. SCP Firmware - -* System configuration -* DDR initialization -* Basic power state management for frequency and C-states -* SCPI commands (Ready, Set/Get Clocks, Set/Get CPU power states) -* Thermal protection (shutdown at 85C, Linux will receive a warning at 75C) -* DVFS support -* Version: 1.0.0-rc3 - -h2. Known Limitations Listed by Software Component - -h3. AOSP Filesystem - -* This build has been configured with interpreter support and optimizations have been incorrectly disabled. Java performance as a result is poor. -* HDLCD issues include a lack of double buffering meaning tearing can be seen -* HDLCD compatibility with monitors is variable at this time -* OpenCL support is not present at this time and will be enabled in a future release - -h3. Linux Kernel - -* The big.LITTLE support is functional but has not yet been tuned for efficiency and performance. - -h3. UEFI - -* No display controller support -* No USB OHCI support. Only EHCI is supported - -h3. ARM Trusted Firmware - -* Does not support changing the primary core using SCC General Purpose Register 1. -* Does not support bringing up secondary cores using PSCI CPU_ON when they have been enabled at boot time by SCP using SCC General Purpose Register 1. - -h2. Android AOSP Patch Summary - -The following list of patches developed by ARM and Linaro engineering teams were applied to Android AOSP dated June 1st 2014 to get Android booting to UI on the ARMv8-A Juno development platform.
