"Vision is not enough, it must be combined with venture. It is not
enough to stare up the steps, we must step up the stairs."
~Vaclav Havel
The Linaro 13.03 release is now available for download!
The 13.03 Linaro release highlights the focused efforts of all the
Linaro Teams – Working Groups, Landing Teams and Platform Teams who
have provided all the updates and new features that are integrated on
top of Android, Ubuntu and OpenEmbedded during this release cycle.
The vision of the future of Linux on ARM is brought into focus through
the collaborative efforts of those dedicated to making the vision a
reality one step and one release at a time. The 13.03 cycle
contributions are numerous and continues to venture into new areas of
the ARM ecosystem with each release.
13.03 was a exceptional cycle for the Linaro Android Team. There was a
lot of planning done during the most recent Linaro Connect event in
Hong Kong and some of those plans have already been put into action
during this cycle. The initial bring up of Android for Arndale as an
engineering platform is now complete and we now have a Tiny Android
build for Arndale. Engineers should see an Android with GUI released
for the 13.04 Linaro release cycle. The Origen-Quad build is now
updated with the new bootloaders and the needed changes for
linaro-image-tools have been completed. Bernhard Rosenkränzer,
Android Engineer at Linaro did an exceptional job in making the current
toolchain available natively inside Linaro Android builds. The builds
now include gcc, g++, vim, make, a terminal emulator and a vi-friendly
keyboard; however, compiling the kernel on the board itself has yet to
be tried. The team encourages interested individuals to give a try and
report any bugs. Axel Fagerstedt, Android Engineer at Linaro, did also
excellent job in unifying all the different manifests with the groups
feature. The team started with 17 manifests and have now come to
1 manifest supporting 8 different builds and one additional manifest
for a member build. The released toolchains are now being checked into
a prebuilts/ git repository and pulled in by the manifest as opposed to
being downloaded as separate tarballs. This is the approach used by
AOSP to distribute the toolchain. The Linaro Android Team have also
enabled CTS in LAVA for 4.2. The support for CTS in lava-android-test
was reworked for stability during the upgrade and as a result more than
99% of CTS tests are now passing for Galaxy Nexus with linaro-android
build when tested manually with lava-android-test. CTS was enabled for
the engineering builds; however, more investigation need to be done on
CTS tests that are not getting executed in LAVA for these engineering
builds.
The Linaro Kernel Working Group work for the 13.03 cycle includes
depopulate the Exynos <mach-exynos/include-mach> directory, convert
UX500 to common clk, refactor EHCI controller code, depopulate the UX500
and plat-nomadik <mach/*> and <plat/*>, Android alarm-dev compat_ioctl
support updates, improvements to eMMC Power Management support.
On the Automation and Validation front, LAVA now supports Arndale
booting with UEFI and the bootloader configuration is being done
"on the fly".
The Linaro Graphics Team posted the following patches for acceptance
upstream during the 13.03 release cycle. Version 10 of CMA-ION patches
were posted by Benjamin Gaignard. Tom Gall updated and posted
the Android piglit enablement patches for OpenGL ES 2 as well as
Version 1 of variable-index-* shader-tests extended for Android and
Linux. Version 1 of debugfs support for dma-buf was posted by
Sumit Semwal and Version 9 of DRM FIMD DT support for Exynos4 DT
machine was posted by Vikas Sajjan.
The Linaro Power Management Working Group has upstreamed the dynamic
timer irq affinity--set up the timer irq affinity to the CPU concerned
by the first timer expiration. The cpufreq driver for IKS is now
optimized and analysis of HMP scheduler optimizations using bbench and
their applicability to A15 SMP systems is now complete. Updates to sched
include a modified timer and workqueue framework to allow migration to
non-idle CPUs. Powerdebug was ported and now available on the Android
platform.
The Linaro Toolchain Working Group had a busy 13.03 release cycle as well.
Changes to the Toolchain binaries release include Linaro GCC being
updated to GCC 4.7.2+svn196272, includes arm/aarch64-4.7-branch up to
svn revision 196225. Linaro QEMU 2013.03 was also released earlier this
cycle and is based off upstream (trunk) QEMU --1.4.0 release-- and
includes a number of ARM-focused bug fixes and enhancements. Updates
for this release include ARM KVM support patches which are in sync with
the ABI as committed to the upstream Linux kernel for 3.9--note:
this feature is still under development, but will no longer be subject
to kernel-vs-userspace ABI breaks.
The Linaro Enterprise Group (LEG) announced that the initial GRUB port
on ARM UEFI is now available and the tree can be found on
https://code.launchpad.net/~leif-lindholm/linaro-grub/arm-uefi
We encourage everybody to use the 13.03 release. The download links for
all images and components are available on our downloads 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/GetSourcehttp://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

This is to let you know that the migration of lists.linaro.org has been
successfully completed.
As per the email I sent on Wednesday, it may take some time for the new
address of the server to be seen by your computer. You can check this by
trying to connect to the web site:
http://lists.linaro.org/
If you are able to connect and you do not get an error, this means you are
connecting to the new server and you can send email to the lists.
If you experience any problems after the weekend and you find that you
still cannot connect to the server, please reply to this email to let us
know.
Regards

Hello
You are receiving this email because you are subscribed to one or more
mailing lists provided by the lists.linaro.org server.
IT Services are announcing planned maintenance for this server scheduled
for *Friday 15th March 2013, starting at 2pm GMT*. The purpose of the work
is to move the service to another server. There will be some disruption
during this maintenance.
In order to ensure that you do not accidentally try to use the service
while it is being moved, the current server will be shut down at 2pm.
A further email will be sent on Friday afternoon to confirm that the
migration of the service is completed. However, due to the way servers are
found, it may take a while before your computer is able to connect to the
relocated service.
After the old server has been shut down, email sent to any of the lists
will be queued, but it is possible that the sending server will still
trying to deliver the email to the old server rather than the new one when
it is started.
It is therefore *strongly* recommended that you do not send any email to an
@lists.linaro.org email address until you can connect to the new service,
which you will be able to test by trying to use a web browser to connect to
http://lists.linaro.org after you receive the email confirming that the
migration has been completed. Since the old service will be shut down, if
you are able to connect, you can be sure you have connected to the new
service.
If by Monday you are still unable to connect to the service or you are not
able to send email to an @lists.linaro.org email address, please send an
email to its(a)linaro.org.
Thank you.
Regards
Philip
IT Services Manager
