"When I was a boy and I would see scary things in the news, my mother
would say to me, ‘Look for the helpers. You will always find people
who are helping."

The Linaro 15.04 release is now available for download!
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:
* Linux Linaro 4.0-2015.04 is released:
* based on v4.0 release
* updated linaro-android topic: aosp/android-3.18 branch has been merged
* GATOR topic: version 5.20.1
* updated integration-linaro-vexpress64 topic by ARM LT (FVP Base
and Foundation models, and Juno support)
* updated topic from Qualcomm LT (IFC6410 and DB410c boards support):
* Resource Power Manager (RPM) - MSM Shared Memory Driver (SMD) driver
* quite some changes under drivers/gpu/drm/ related to adv7511
and adv7533 support
* ASoC support for QCOM platforms
* external Connector Class (extcon) support (used for USB VBUS
and ID detection)
* Linaro builds of AOSP 15.04 is released:
* baseline updated to android-5.1.1_r1
* updated Nexus 10 CI for LAVA testing
* added Optimus A80 Android Kitkat build
* Linaro OpenEmbedded 2015.04 is released:
* removed stress recipe in favor of oe-core recipe
* updated linux-linaro to ll_20150422.0 (based on 4.0)
* libevent-fb: OE-core updated to 2.0.22, fix require statement
* APM mustang boot failure
(https://bugs.linaro.org/show_bug.cgi?id=1501) was tracked down to
using 'arm64' as U-Boot arch for the initramfs header while the vendor
U-Boot 2013.04 expects 'arm'.
* upstreaming:
* strace: fix build for aarch64
* libgpg-error 1.18: simplify tuple handling and add armv8b support
* Linaro Ubuntu 15.04 is released:
* updated packages: LSK 3.10.74/3.14.39 and linux-linaro 4.0 kernels
* U-Boot: upstream fastboot support:
* Add HiSilicon D01 platform support to Debian installer:
* Updated android-build job to work with docker slaves
* Cleaned up ILP32 build job
* LSK: enable debug options on regular builds
* linux-linaro: ll-fold.sh script fixed to work correctly with newer
git versions
* CI bring up: tshark board Android member build
* Added Ubuntu arm64 gnome rootfs
* Added D01 platform to Coresight CI loop

released artifact on the release information:

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:
http://wiki.linaro.org/Platform/DevPlatform/Ubuntu/ImageInstallation

The Systems team has been working on making clone/pull operations work
better for people in different geographical regions:
https://wiki.linaro.org/Platform/Systems/GitHA
We currently have a DNS test alias named "git-geo.linaro.org" that
should direct users to the server that will deliver the best connection.
Before switching over the real "git.linaro.org" DNS entry, I was hoping
to get some more people using this new system to verify its working
correctly.
= How you can help
1) update "git.linaro.org" entries in your .git/config files to be
"git-geo.linaro.org"
2) let me know how it goes for you

Add test which verifies capacity calculation on arm
architecture platforms.
This will work on any platform that uses parse_dt_topology() arch hook
to set cpu capacity. Currently only arm (not arm64) platforms do this.

-Other info
-==========
-- PM-QA is one of the tools in the external opensource modules in the external
- path of android. For building on android, the makefile Android.mk is used to
- build the testsuite with a makefile for each subtest.
-- Incase you are extending a subtest, say a new script which will test a
- feature. Add the test number in the Android.mk, in addition to this if its
- using a source file (say .c), add the source file in the Android.mk so that
- it gets built.
-- LAVA scripts are used to trigger the pm-qa tests.
-- Similarly for non-android adding a script and txt (test description) pair is
- needed to extent the suite.

+
+Bugs
+====
+If you believe that you have encountered a bug, please file a bug report on
+Linaro Bugzilla at https://bugs.linaro.org. Once you log in, click on
+"New" --> "Power Management" --> "PM-QA" as the component. Then fill
+in the form.
+
+Helpful tips for filing a bug report:
+ 1. Provide logs, be verbose as possible
+ 2. Outline steps to reproduce the bug
+ 3. Describe the environment you are running PM-QA on (e.g. Android,
+ OpenEmbedded, Ubuntu, etc.)
+ 4. What hardware you're using
+
+Questions/Comments
+==================
+Please submit questions and comments to the linaro-dev mailing list at
+linaro-dev(a)lists.linaro.org with "PM-QA" as part of the subject.
+
+Contributions
+=============
+If you wish to submit patches to improve PM-QA, please send them to
+the linaro-dev mailing list at linaro-dev(a)lists.linaro.org with
+"PATCH PM-QA" as the subject prefix.
+
+All scripts in PM-QA must be POSIX-compliant and cannot use any
+bashisms. At a minimum, they must run in Android and Ubuntu
+environment and have text files that include their descriptions.
+
+Additional notes on new tests
+=============================
+PM-QA can be extended with more functional tests by following a few
+simple rules.
+
+a. Add the test (usually a shell script) and its associated
+description (in a .txt file with the same name) in the appropriate
+subdirectory
+b. Change the Android.mk makefile in the subdirectory as appropriate.
+You will need to change the 'test_num' variable at a minimum. If
+you're using other source files (say .c), add that to the makefile as
+well.
+c. Create a draft specification for your test that can be added to the
+wiki page[1]
+d. Make sure your shell scripts do not use bash-specific constructs.
+Run them with the #!/bin/sh as the interpreter directive instead of
+#!/bin/bash.
+e. PM-QA can be found in the external opensource modules in the
+external path of android sources hosted at Linaro. It is synced with
+the latest version of PM-QA everytime a new release is made.
+Android.mk makefiles are used to build the test suite - there is one in
+each sub-directory.
