it will be simple in retrospect. ~Edward Teller
The Linaro 13.09 release is now available for download!
The 13.09 release includes the first formal release of the Linaro Stable
Kernel (LSK). The LSK will provide access to new Linaro features integrated
with the most recent kernel.org Long Term Stable (LTS) release.
For more details, please refer to LSK website - https://wiki.linaro.org/LSK
Here are some of the other highlights, by group:
* LAVA has seen significant new hardware additions, with more expected over
the next couple of months. In the hardware area, the Calxeda Midway server
is now available to Linaro developers and the Linaro Networking Group (LNG)
rack has been deployed. Software support is available for the LAVA
Multi-purpose Probe (LMP) in lava-test-shell and the SD-MUX is in staging.
The LAVA team has also completed the migration from Bazaar (bzr) to Git
with this release.
* The Graphics working group has included a mix of essential updates and
new work for future solutions including dma-buf changes for 3.12, Common
Display Framework (CDFv3) prototyping and implementation on member hardware,
an update of libjpeg-turbo including a refresh for Android plus new ARMv8
support, and an initial libpng port of NEON acceleration to intrinsics.
* Also leading the way on developments for the future, the Virtualization
team has completed upstreaming of AArch64 preparation support for QEMU and
the first patches for Xen bring up on APM ARMv8 hardware. Many items are
also in the upstream pipe, including ARMV7-A Guest Migration functionality,
Xen device tree editing, mach-virt and the ARMv8-A port of libvirt.
This last item, libvirt, is now functional on ARMv7-A and functional
testing has started.
* If you’re interesting in an approach for converting older code that uses
wake locks to code using wakeup sources, Zoran Markovic from the Power
Management working group has posted a blog discussing this here:
http://www.linaro.org/linaro-blog/2013/08/26/converting-code-implementing-s….
The group has also released Linaro Powerdebug 0.7.1-2013.09 and
Linaro PM QA 0.4.4-2013.09.
* In the 13.09 release, in addition to the Linaro Stable Kernel (LSK)
3.10.12-2013.09, the Builds and Baselines team have released Linux Linaro
3.11-2013.09, Linaro Toolchain Binaries 2013.09 and various improvements
on the baselines. In collaboration with the ARM Landing team, the AArch64
OpenEmbedded Engineering Build for ARM Fast Models for ARMv8 is produced,
validated and released, based on the latest AArch64 open source software
from Tianocore EDK2 (UEFI), the Linux kernel, ARM Trusted Firmware and
OpenEmbedded. This release includes Linaro OpenEmbedded images for
Foundation, Versatile Express and FVP Base fast models from ARM.
We encourage everybody to use the 13.09 release. The download links for
all images and components are available on our downloads page:

The Linaro 13.08 release is now available for download!
The 13.08 release includes the "beta" version of the Linaro Stable
Kernel (LSK), the big.LITTLE MP patchset available in both LSK and
Linux Linaro 3.11-rc6, and sees the first major output from
the Linaro Networking Group (LNG).
Over the past few months, the LSK team has been developing a process to
build and maintain a stable kernel based on the latest LTS kernel serie
and has produced monthly interim LSK releases since May to verify
the process. On August 4th, Greg Kroah Hartman announced 3.10 as
the next long-term stable (LTS) kernel series and this means the LSK
team is able to produce a preview LSK release, based on the 3.10.9
stable kernel. Next month's 13.09 delivery will be the first official
LSK release. The LSK git repository is located at:
https://git.linaro.org/gitweb?p=kernel/linux-linaro-stable.git
This release includes a significant amount of work from the Linaro
Networking Group (LNG), which was established in February. LNG moved
its kernels to 3.10.6 and 3.10.6 + rt3 and the real time (PREEMPT_RT)
patch set for 3.10.6 + rt3 became available. Work on the Linaro
OpenEmbedded baseline progressed rapidly with the merging of the
meta-bigendian layer and booting of the LNG images based on this
baseline on the Arndale board.
The Linaro Enterprise Group continued to build on its work in earlier
releases, but a key highlight was getting the Continuous Integration
(CI) loop for OpenJDK-8 on ARMv8 up and running. Work remains to get
all the tests passing and to amplify the range of the test suites used.
In addition, the patch set enabling bit sliced AES for NEON have been
completed and merged upstream in the OpenSSL project.
We encourage everybody to use the 13.08 release. The download links for
all images and components are available on our downloads page:
http://www.linaro.org/downloads/

The Linaro 13.07 release is now available for download!
The 13.07 Linaro release highlights the collaborative 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,
OpenEmbedded and Ubuntu baselines during this development cycle.
With this release we are reminded of the great "players" who come together to
plan and create the future of Linux on ARM. Seeing the synergic efforts of
Linaro, its members and the greater Open Source Community is what drives our
future--the future of Linux on ARM.
On the Builds and Baselines front, the Linaro Stable Kernel preview 2013.07 was
updated: based on the 3.10.1 stable kernel tree; including ARM MP patch set,
IKS VExpress TC2 and Power efficient workqueue support, Android v3.10
experimental patch set from AOSP. Linaro OpenEmbedded baseline added
libjpeg-turbo as the preferred provider for jpeg, updated to the Linaro GCC
4.8-2013.07 release and switched builds to use Linaro versions of binutils and
eglibc (2.17). Linaro Android baseline reports that the Arndale platform has
been updated with display support on HDMI using software graphics stack,
and is built with the Linaro GCC 4.8-2013.07 release as well.
The Linaro toolchain Working Group released Linaro GCC 4.8 and 4.7 2013.07
which added address Sanitizer support for ARM along with the new -mrestrict-it
option support. The backports of support for further AArch64 aand ARMv8 AArch32
instructions were added. Linaro eglibc 2.17-2013.07 has optimized string
functions for AArch64: memcmp, memset, memcpy, memmove, bzero, strcmp, strlen,
strnlen, strncmp.
As of this release, the Linaro LAVA lab now hosts 75 devices including 4 new
member systems and an actual “LMP stack” which is a tower of 5 LAVA
Multi-purpose Probe boards (including SDMux support) is now being prototyped
and tested. Multi-node test is currently in beta, but a live demo from LCE13
can be seen at: http://multinode.validation.linaro.org sandbox.
Advanced LAVA configuration options were reviewed during this cycle and topics
that were discussed included managing a multi-machine (LAVA Servers & worker
nodes), deployment with salt-stack (LAVA Cambridge Lab), generic test
integration, creating a test parser, overriding boot commands and the new
interactive boot command support in LAVA.
We encourage everybody to use the 13.07 release. The download links for

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 OpenEmbedded-based images
=======================
With the Linaro provided downloads and with ARM’s Fast Models virtual platform,
you can boot a virtual ARMv8 system and run 64-bit binaries.
For more information please see:
http://www.linaro.org/engineering/armv8
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:

Without deviation from the norm, progress is not possible. ~Frank Zappa
The Linaro 13.06 release is now available for download!
The 13.06 Linaro release highlights the progressive 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,
OpenEmbedded and Ubuntu baselines during this development cycle. With this
release we celebrate the 3rd anniversary of Linaro and can truly begin to see
how deviation from the norm and the "way things were" have been a catalyst to
progressing the future of Linux on ARM thus bringing the collaborative efforts
of Linaro, its members and the greater Open Source Community together to build
upon.
It’s been a very active cycle for the Builds and Baselines team, reporting that
the Continuous Integration (CI) loop for the Linaro Stable Kernel (LSK) Android
proof of concept which is based on 3.9.6 kernel version was set up and includes
the big.LITTLE IKS and MP patches (also called beta patchset). Support for
Kernel CI loop with Android filesystem was added to android-build and CI loop
was set up to track the ARM Landing Team (LT) integration tree. The HiSilicon
member build with complete CI loop was set up and now tracks the LT kernel
tree.
The LAVA team was equally as productive as LAVA support for tarballs (tgz),
Debian and RPM packaging has been reviewed and explicit support has now been
created outside the use of lava-deployment-tool. Additionally, LAVA now
supports KVM devices, which can be used for providing x86 boxes for
cross-building and other tasks where there is no need (or no possibility) of
using actual ARM devices.
Progress on the kernel front includes the continuous porting effort to
multi-platform support as well as Integrator PCI DT, the u300 work and
the Nomadik clock DT were pulled into ARM SoC tree. The team also posted
the first version of the ARM 32 bit uprobes support for public review and
has got portions of eMMC power management work accepted upstream.
The QA Services team, in collaboration with the Power Management WG, have
fully automated big.LITTLE benchmarking noting that when a build is done,
it is automatically benchmarked and results are uploaded to a google
spreadsheet. The initial cleanup of bugs in Linaro launchpad projects has now
been completed and the Piglit test suite is now run on each Android build for
PandaBoard.
We encourage everybody to use the 13.06 release. The download links for
all images and components are available on our downloads page:

The only way to predict the future is to have the power to shape it. ~Eric Hofer
The Linaro 13.05 release is now available for download!
The 13.05 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,
OpenEmbedded and Ubuntu baselines during this development cycle.
It is through these monthly releases that Linaro, our members and community
do more than predict the future of Linux on ARM; we plan and progress that
future with open and collaborative teamwork and success. The 13.05 Linaro
release gives a vision of that future as we highlight the accomplishments
of each of our teams. Those accomplishments include:
The foundation for the Linaro Stable Kernel (LSK) tree has been prepared.
LSK will track the kernel.org community released LTS (Long-Term Stable)
kernel tree, and Linaro will add member selected features, platform support
and bug fixes. During the 13.05 development cycle, a preview/proof of concept
has been delivered, based on linux-3.9.4 stable tree with ARM LT topic
branches (TC platform support) and big.LITTLE work (MP and IKS).
The announcement of big.LITTLE in-kernel switcher (IKS) code now available
to the public. “This code was also developed for and tested on the Versatile
Express TC2 development platform. An MCPM backend and possibly a special
cpufreq clock driver are required for this code to be usable on other
platforms,” wrote Nicolas Pitre in his announcement to the Linaro
development mailing list. More information and helpful links can be found at:
http://www.linaro.org/linaro-blog/2013/05/02/the-linaro-iks-code-now-public…
Quality remains a focus at Linaro and on the testing and validation front,
members of the LAVA team completed and tested the functionality of the first
prototype production run of LAVA LMP. The Platform teams also announced that
Texas Instruments Beaglebone Black is now running in LAVA. As part of
the effort to improve the developers experience with LAVA, the different
client tools were also consolidated into a single package in order to
make it easier for the team to provide new features for LAVA users.
The Builds and Baselines team mirrors the quality efforts of the testing and
validation team and notes various accomplishments across several of the Linaro
Teams and Working Groups (WG). The team notes that a detailed Compatibility
Test Suite (CTS) report in the standard format is now being generated in LAVA
and the QA Services team will include these reports in its weekly/monthly
testing reports for platforms in LAVA. Another highlight for this cycle
includes the completion of the Galaxy Nexus CI loop and images (without
graphics acceleration) can be deployed with a graphics overlay for testing
in LAVA. The team also reports that the full Android engineering build for
Arndale is now available with virtual framebuffer.
The various releases that help make up the Linaro 13.05 release include:
* Linaro UEFI 2013.05
* Linaro Stable Kernel (LSK) preview 3.9.4-2013.05
* Linux Linaro 3.10-rc2-2013.05
* Linaro GCC 4.8-2013.05 and 4.7-2013.05 (based off the latest GCC releases)
* Linaro Toolchain Binaries 2013.05
We encourage everybody to use the 13.05 release. The download links for
all images and components are available on our downloads page:

Unity is strength... when there is teamwork and collaboration, wonderful
things can be achieved.
~Mattie Stepanek
The Linaro 13.04 release is now available for download!
The 13.04 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 13.04 release cycle has been one of the busiest and most productive
cycles to date. There were 7 individual team releases during this cycle
all of which help build the foundation of the Linaro 13.04 release.
It is through the teamwork and collaboration between Linaro, its members
and community that the achievements of each are unified in these monthly
releases and continue to build the future of Linux on ARM.
Quality builds continue to be the foundation on which the future of Linux
on ARM is being built, this quality is ensured through our testing and
validation teams. Fedora support has been merged in LAVA and users can
now submit LAVA jobs using a Fedora pre-built image. The QA Team
announced that tests to cover big.LITTLE cluster init and shutdown have
been added to the big.LITTLE core test suite and big.LITTLE extended test
case scenarios have been implemented.
Our Builds and Baselines teams are the footers that support this
foundation of collaboration and during the 13.04 release front, Dalvik VM
unit test has now been automated and the native toolchain on Android has
been updated to Linaro GCC 4.8. The Android tree has been updated to
compile with GCC 4.8 based toolchains and all related changes have been
upstreamed. The ARMv7 KVM enabled kernels intergrated into our pre-built
images are now built daily and tested in Linaro's CI loop.
The OpenEmbedded ARMv8 engineering build now provides 64bit HipHop VM
requirements for porting and optimization purposes. The OpenEmbedded test
cases have been automated and a current list of these tests can be found
at: https://git.linaro.org/gitweb?p=qa/test-definitions.git;a=tree;f=openembedd…
The Linaro Kernel WG focused on the following areas during this release
cycle: refactor EHCI controller code, depopulate Exynos/ux500/plat-nomadik,
expand binder unit test, improve eMMC power management support, port some
of the platforms to multi-platform support, Android upstreaming effort,
and much more.
Additional highlights include the release of a big.LITTLE porting guide
by the Power Management WG and Linaro GCC 4.8 by the Linaro Toolchain WG.
We encourage everybody to use the 13.04 release. The download links for
all images and components are available on our downloads page:
http://www.linaro.org/downloads/
