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.

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. The download links for all
images and components are available on our downloads page:

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)

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:

The Linaro Toolchain Working Group is pleased to announce the release
of Linaro QEMU 2011.06.
Linaro QEMU 2011.06 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 release introduces two new features; these are still experimental
so please report any issues:
- A model of the Gumstix Overo board; this is an OMAP3 based system
similar to Beagle but with the advantage of having supported
onboard ethernet.
- USB keyboard and mouse support, if your kernel includes support for
the OMAP3 OHCI controller (not just EHCI). Try adding
"-device usb-kbd -device usb-mouse" to your QEMU command line for
Beagle or Overo models.
Other interesting changes include:
- A fix for the lack of graphics output on the Beagle model when
running the Linaro 11.05 final release image
- Suppression of the "Bad register 0x000000f8" warnings provoked by
the Linaro 11.05 final release kernels
- As usual, various minor correctness fixes and other upstream changes
Known issues:
- The beagle and beaglexm models still do not support USB networking
- There are some gcc 4.6 warnings about "variable set but not used"
which have not yet been resolved; Ubuntu Oneiric's gcc makes these
non-fatal, but if you're building with an upstream gcc 4.6 you may
need to add the "--disable-werror" option to configure
The source tarball is available at:
https://launchpad.net/qemu-linaro/+milestone/2011.06

The Linaro Toolchain Working Group is pleased to announce the release
of both Linaro GCC 4.6 and Linaro GCC 4.5.
Linaro GCC 4.6 is the fourth release in the 4.6 series. Based off the
latest GCC 4.6.0+svn174261, it adds new optimisations and vectoriser
improvements.
Interesting changes include:
* Updates to 4.6.0+r174261
* Blocks can now vectorise into ORN and BIC instructions
* Support for half word to double word multiply and accumulate operations
* Better support for other widening multiply operations
* Further performance improvements in NEON strided loads and stores
* Performance improvements targeted at EEMBC CoreMark
Fixes:
* PR target/48454: Set the lengths correctly for the case with Quad vectors.
Known issues:
* Building Python 2.7 with -mfpu=neon exposes a bug in vmov.i64 in
binutils 2.20.51. Please use 2.21 or later.
The strided load/store improvements allow the vectoriser to
efficiently access values that occur at every n'th address, such as
all of the red values in a RGB image or all of the left channel
samples in a interleaved audio array. For example, a plain C function
that converts between RGB and CYMK now runs 7.3 x faster on an A9.
Linaro GCC 4.5 2011.06 is the eleventh release in the 4.5 series.
Based off the latest GCC 4.5.3+svn174250, it is a maintenance focused
release.
Interesting changes in 4.5 include:
* Updates to 4.5.3+r174250
Fixes:
* LP: #744754: ICE in reload_cse_simplify_operands, at
postreload.c:402 with neon optimized code

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

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
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,
