The Linaro Team is pleased to announce the release of Linaro 11.10, Linaro’s fifth release delivered on a monthly cadence. This release includes components delivered by all Linaro Teams: Working Groups, Landing Teams and Platform Teams. Again, the effort brings a lot of updates and new features, integrated on top of Android and Ubuntu. Among the improvements brought by this release and delivered by Linaro engineers, some prominent items worth mentioning are: * This month Linaro Ubuntu LEB images are based on Ubuntu 11.10 (Oneiric) featuring the latest and greatest Unity 3D experience ported to OpenGL ES by the Linaro Graphics Working Group. Note that this is one month ahead of plan and a remarkable achievement of the Developer Platform Team with support from the whole Linaro engineering organization. * The Linaro Android LEB also saw continued enablement improvements across all boards with functional audio through jacks and HDMI on PandaBoard being one prominent example. All Android LEBs have been moved over to a 3.x based kernel and include a TJBench port for continuous libjpeg benchmarking in the lab. * Linaro Kernel CI started a pilot exploring a new feature that allows maintainers to submit git trees as one time jobs for building and lab testing. Also Developer Platform Team now uses the Kernel CI infrastructure to continuously package and test a first LEB kernel. * To improve tracking of a continuous stream of build and runtime results coming from the kernel CI infrastructure, a waterfall type reporting tool provided by LAVA has been developed and added to the dashboard (http://validation.linaro.org/lava-server/kernel-ci-views/index). Initial Snowball boards have landed in the lab and the LAVA test repository incorporated support for power management CPU hotplug tests and "Insanity", a multimedia test suite. * Finally, even more sophistication on the CI front was introduced for Android through integrating Gerrit into the Linaro Android Build Service. Reviewed changes now automatically get build tested and a bot posts the outcome to the gerrit ticket, making it easier to catch issues before they are integrated into the official Linaro Android trees. * The Graphics Working Group has integrated GLEW with OpenGL ES support on Ubuntu 11.10 images. It is packaged and available at the Linaro Overlay PPA. * Linaros Kernel efforts improved Device Tree support for member platforms and made a first step in improving managability of board defconfigs through merge_config.sh script that helps to maintain config overlays. This has the potential to reduce redundancy carried by the various board defconfigs in the upstream kernel. * After a few month of investment into libjpeg-turbo optimization by the Multimedia Working Group, the recently started libpng effort carried successes this month and an initial component release of libpng 1.5 with a first set of ARM optimization is included in this release. PNG is a key building block of web browsing technology and improvements will be a direct benefit for usability in todays ARM based products. * This month Linaro GCC comes with critical performance fixes and developers using Linaro GDB can enjoy an improved native debugging experience through gdbserver. The Toolchain Working Group started to transition their custom validation infrastructure to the LAVA lab this cycle. The complete transition is expected to take additional months, but once complete it will free up engineering resources in the Working Group to focus on code. We encourage everybody to use the 11.10 release. The download links for all images and components are available on our downloads page: http://www.linaro.org/downloads/ See the detailed highlights of this release to get an overview of what has been accomplished by the Working Groups, Landing Teams and Platform Teams. The release details are linked from the "Details" column for each released artifact on the release information: http://wiki.linaro.org/Cycles/1110/Release#Release_Information For better support and tracking the hardware sanity of our supported boards, we now publish a board support status with each monthly release.

Linaro 11.09 released

by Fathi Boudra

The Linaro Team is pleased to announce the release of Linaro 11.09, the Linaro’s fourth release delivered on a monthly cadence. This release includes components delivered by all Linaro Teams: Working Groups, Landing Teams and Platform Teams. As usual, it brings a lot of updates and new features, integrated on top of Android and Ubuntu. Among the improvements brought by this release and delivered by Linaro engineers, it worths mentioning: * Beta release of our Continuous Integration (CI) Build Service focused on continuous large scale kernel tracking. This is a first step in support of the new Kernel Working Group developement model based on a stable tree and continuous integration of the Working Groups and Landing Teams Kernel. * Ubuntu based image distribution format has seen a big improvement through the arrival of hardware packs v2. This new format will allow more flexibly in shipping our growing board support alongside our hardware independent Ubuntu based images. * On the hardware enablement front, both Android and Ubuntu images have seen good improvements on most of our primary target boards. This includes the availability of Wi-Fi and Bluetooth for Android PandaBoard builds and audio (ALSA UCM) on our Ubuntu builds with proper kernel support. * Android image builds are first to incorporate the whole userspace and kernel using the Toolchain Working Group proposed -O3 option. * The Graphics Working Group added a xrender based compositing test to GLCompBench and merged a 2D convolution benchmarking scene and 3D screensaver inspired benchmarking scene to GLMark2. With these improvements, our set of graphics tests grows again by tests designed with real user experience use cases. In addition, GLMark2 is now integrated on all our Android builds and is automatically run in Linaro Validation Farm. * The Kernel Working Group continued their outstanding work to always make the very latest available ARM bits included as part of our linux-linaro 3.0.4 based release. We include the ARM merged code of 3.1-rc1 from Russell King's tree, stable and ready for consumption. * LAVA saw various plumbing improvements. The number of PandaBoards deployed got a significant boost with roughly 15 boards now being active 24/7. * Last but not least, we have the usual updates of our core components from the Toolchain Working Group, including a fresh code drop for gcc-linaro, gdb-linaro and qemu-linaro. All those of course come pre-integrated for direct use on Ubuntu host as well as Android or Ubuntu targets. We encourage everybody to use the 11.09 release.

Linaro QEMU 2011.08 released

by Peter Maydell

The Linaro Toolchain Working Group is pleased to announce the release of Linaro QEMU 2011.08. Linaro QEMU 2011.08 is the latest monthly release of qemu-linaro. Based off upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes and enhancements. This month's release is primarily minor improvements: - Fixes LP:816791: ARMv6 cp15 barrier instructions now work in linux-user mode as well as system mode - Support for ARM1176JZF-S core has been added (thanks to Jamie Iles <jamie(a)jamieiles.com>) - Add workaround for kernel bug LP:727781 (which has resurfaced in 3.0) to suppress warnings about bad-width omap i2c accesses Plus of course new upstream fixes and improvements. Performance: When running qemu in system mode with an SD card image we have determined that performance is best when the image is in writeback caching mode. This significantly increases the performance of the SD card (by factors of 10 or more). An example command line option is: -drive if=sd,cache=writeback,file=my-sd-card.img Note that cache=writeback may result in data not being written to disk if the host system powers down unexpectedly (guest crashes or powerdowns are not a problem). Known issues: - The beagle and beaglexm models still do not support USB networking - There may be some problems with running multithreaded programs in linux-user mode (LP:823902) The source tarball is available at: https://launchpad.net/qemu-linaro/+milestone/2011.08 Binary builds of this qemu-linaro release are being prepared and will be available shortly for users of Ubuntu. Packages will be in the linaro-maintainers tools ppa: https://launchpad.net/~linaro-maintainers/+archive/tools/ More information on Linaro QEMU is available at: https://launchpad.net/qemu-linaro

Linaro 11.07 released

by Mounir Bsaibes

Hi, The Linaro Team is pleased to announce the release of Linaro 11.07. 11.07 is the Linaro’s second release delivered on the new monthly cadence. This release includes components from all Working Groups and Landing Teams as well as set of Android and Ubuntu based images that come with integrated Linaro updates to provide a fastpath to Linaro technology. The 11.07 Linaro release moved all main kernel efforts to Linux 3.0. It features a 3.0 linux-linaro, linux-linaro-android kernel and comes with Linaro Evaluation Builds (LEBs) of Ubuntu and Android based on linux-linaro-3.0 TI Landing Team's kernel. Additionaly, 11.07 saw the Linaro Android move to gcc-linaro 4.6 as the default compiler; this means that all main Linaro efforts are now focussed on the GCC 4.6 series as their baseline. We encourage everybody to use the 11.07 release. The download links for all images and components are available on our release page: http://wiki.linaro.org/Cycles/1107/Release Highlights of this release: * Linaro Evaluation Build (LEB) for Android on PandaBoard is built on Linux 3.0 kernel with gcc-linaro 4.6 as the default compiler which is used for all official Linaro Android Platform builds. This Linaro Android monthly release exhibits the first official Linaro Android Toolchain release based on the most recent gcc-linaro 4.6, and the first Linaro Android release for ST Ericsson Snowball using Landing Team kernel based on linux-linaro-android. On top, Linaro Android 11.07 comes with the more advanced more visually appealing Launcher2 by default. * Android GCC benchmark results for 11.07 release can be found on http://wiki.linaro.org/Platform/Android/AndroidToolchainBenchmarking/2011-07 * Linaro Evaluation Build (LEB) for Ubuntu also uses the most recent linux-linaro kernel based on Linux 3.0 and includes the latest Linaro Cross Toolchain available for Ubuntu Lucid and Natty. ARM DS-5 packages are now available and enabled by default for the developer image. They are packaged and can be easily installed on Ubuntu host and target by simply enabling a "linaro" hosted PPA. The Developer Platform Team continued to improve the developer experience for Ubuntu and Linux based ARM by adding support for cross buildable images to Live-build 3 which makes it easier to produce Ubuntu images in a cross build environment. Additional highlights for our Ubuntu efforts include working hwpacks for all Landing Team low cost boards - a first, libjpeg-turbo integrated and set as the default for Ubuntu/LEB images, and packages delivered by the Graphics Working Group like glcompbench, glmark2 and unity. * Linaro kernel current release is based on the 3.0 stable kernel with a number of changes developed by Linaro and integrated from the 3.1-rc cycle. In addition to the changes already in 3.0, this release of the Linaro kernel includes: the comprehensive ARM kprobes work which extend kprobes to support Thumb-2 kernels, the new processor struct macros, the ARM cpu topology definition, basic Cortex A15 support, DMA infrastructure cleanups, a kernel helper to perform 64-bit atomic operations and multiple enhancements for DT support. * Initial release of Linaro-Android Common tree based on Linaro-kernel 3.0 with addition of ADB functionality to linaro-android tree for OMAP3. * U-boot provides an incremental release with multiple improvements: a better PXE support based on feedback from the Ubuntu ARM server team, generated unique ethernet address based on SOC die id on OMAP4, ability to customize boot command via boot.scr script file or uEnv.txt plain text file, new fdt_high environment variable as part of a fix to allow using all 1G of memory on PandaBoard. * Power Management Team enabled sched_mc for ARM, added topology detection for ARM thus allowing scheduler to be tweaked to save power. * From the Graphics Working Group, this release adds support for OpenGL ES and EGL in GLEW library for ARM Linux, glewinfo and visualinfo utilities support for OpenGL ES, new versions of compiz and plugins-main with updates to the 0.9.5.2 upstream branches, and multiple enhancements to the glmark2 and glcompbench benchmarks for OpenGL ES 2.0. * Toolchain Working Group has released Linaro GCC 4.6 and 4.5. The 4.6 series has new optimisations including improved vectoriser support for shifts, widening multiplies, and peeling; improvements to the swing-modulo scheduler; and fixes multiple bugs found in the last month. * With 11.07 release, the Infrastructure Team have improved creation, testing and usage of the Linaro images. Linaro-fetch-image-ui is a wizard style graphical tool that guides the user through the process of creating a fully functional operating system for Linaro supported hardware, along with a command line that does the same. Pre-built images will be available, the ground work has finished that will allow the production of pre-built images that can simply be copied to a SD card and run without the need to learn about Linaro tools when just trying out a standard image. * This month LAVA main changes is the UI for the dashboard got an overhaul with new features added. Basic UI is added to the sheduler to see the status of boards and jobs. The ability to schedule jobs by device type is also added to the scheduler. The dispatcher has better error handling and preliminary support for Snowball boards and lava-test now streams results while the test is running. * Office of the CTO (OCTO) has produced its first ARM hard-float images (alpha stage). More information on the usage and the work related to those images can be found on https://blueprints.launchpad.net/linaro/+spec/engr-octo-armhf-images * And much more... The release details are linked from the "Details" column for each release artifact on the 11.07 release page. 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 Getting involved ================ More information on Linaro can be found on our websites: * Homepage: http://www.linaro.org * Wiki: http://wiki.linaro.org Also subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro developments: * Announcements: http://lists.linaro.org/mailman/listinfo/linaro-announce * Development: http://lists.linaro.org/mailman/listinfo/linaro-dev * IRC: #linaro on irc.linaro.org or irc.freenode.net #linaro-android irc.linaro.org or irc.freenode.net Known issues with this release ============================== For any errata issues, please see: http://wiki.linaro.org/Cycles/1107/Release#Known_Issues Bug reports for this release should be filed in Launchpad against the individual packages that are affected.

[Announce] Linaro Kernel 2011.05-2.6.38 Snapshot Released

by Deepak Saxena

The Linaro Kernel Working Group (KWG) is excited to announce the availability our May 2011 development snapshot: linux-linaro-11.05-2.6.38 This is the first of a new monthly series of development snapshots from the KWG that will provide a way for developers to work with the Linaro kernels without needing to follow the git tree on a daily basis. As the word "snapshot" implies, these are meant as development kernels and have not been fully validated. You should expect issues and to help us deliver a better kernel in the future, you should file bugs in Launchpad at https://bugs.launchpad.net/linux-linaro. The source tarball is available at: https://launchpad.net/linux-linaro/11.05/11.05-final/+download/linux-linaro… The kernel sources can also be accessed using git at: git://git.linaro.org/kernel/linux-linaro-2.6.38.git tag: linaro-11.05-2.6.38 A pre-packaged kernel for OMAP boards is available at: https://launchpad.net/~linaro-maintainers/+archive/kernel/+files/linux-imag… This snapshot is based on the 2.6.38.7 stable kernel with a number of changes developed by Linaro and integrated from upstream trees including the 2.6.39, OMAP, and Power Management trees to name a few. The changes from 2.6.38.7 include: * Initial Device Tree support for MX51, MX53, Overo, SMDKV310, Beagle, IGEPv2/v3, Panda, Tegra, and Versatile boards. This support allows memory size and board type to be passed via the Device Tree. * The ARM kprobes code has been updated to correctly handle a number of instructions that did not previously work and to work on kernels w/o frame pointers. * The coredump code has been updated so you can now analyze VFP register state using GDB. Using this feature requires the upstream GDB trunk tree or the Linaro snapshot available from https://launchpad.net/gdb-linaro/+download * CPUIDLE support for Samsung Orion has been added, allowing for longer battery life on platforms based on this chipset. * Experimental support for LTTng on ARM, allowing developers to perform deep analysis of system state transitions. See http://lttng.org/ for more information on using LTTng. A full changelog against 2.6.38.7 is available at: https://launchpad.net/linux-linaro/11.05/11.05-final/+download/CHANGELOG-li… High Priority Known Issues: * The combination of a device-tree enabled kernel and and Linaro's 2011-03 u-boot will make WiFi and HDMI unuseable on the IGEP board. (LP #768680) * imx51 randomly truncates serial input at 31 characters (LP #754254) * OMAP Beagle C4: kernel does not reliably find SD card on boot (LP #712175) * wl12** driver causes networking to hang on ubuntu-desktop image (LP #785739) * Only half of RAM useable when using Device Tree on Panda board (LP #707047) Mailing list: http://lists.linaro.org/mailman/listinfo/linaro-dev Questions? https://ask.linaro.org/

Linaro Image Tools 0.4.8 released

by James Westby

Hi, The Linaro Infrastructure team is pleased to announce the release of Linaro Image Tools 0.4.8. Linaro Image Tools offer a set of tools for use with Linaro images. Highlights of this release: * Fix booting when using a lot of kernel command line arguments - https://bugs.launchpad.net/linaro-image-tools/+bug/788765 * Added mpurate=${mpurate} kernel boot argument for Beagle Board. This allows the bootloader to set the valuefor the kernel. * Allow hwpacks to remove packages from the rootfs if needed. This allows us to provide hwpacks containing alternative implementations of parts of the stack (e.g. accelerated graphics libraries.) * Fix the output of the linaro-hwpack-create command. It will now report progress and the --debug option will once again provide debug information. Thanks, James Westby

ANNOUNCE: Linaro Plan Reviews (May 31st to June 8th)

by Christian Robottom Reis

Hello there, Starting next Tuesday, May 31st, Linaro tech leads will be running a set of public phone calls to present official plans for our engineering units. Calls are daily at 15:00 UTC, and there are local dial-in numbers for most countries around the world. Schedule and details are listed here: https://wiki.linaro.org/Cycles/1111/PublicPlanReview For each call we will provide a set of slides discussing features planned and the blueprints that specify and track them. The calls are open to the general public; anybody is welcome to dial in and listen. Questions can be asked via IRC using #linaro-meeting on Freenode; details on how to access IRC itself are also linked to from that page. Calls will also be recorded and available for later perusal. If you'd like a daily reminder of the call topic let me know and I'll put you on the reminder list. The first call, on Tuesday itself, will cover Power Management, and be hosted by Amit Kucheria. See you there, -- Christian Robottom Reis | [+55] 16 9112 6430 | http://launchpad.net/~kiko Linaro Engineering VP | [ +1] 612 216 4935 | http://async.com.br/~kiko
