Hello All, As part of greater Continuous Integration (CI) efforts at Linaro, the Infrastructure Team is tasked to develop and maintain a jenkins based, versatile service run in the cloud that will drive the build part of the continuous integration loop for engineering components. After an intense 11.09 cycle focused on developing a solution for doing large scale kernel CI building and testing, we are pleased to announce that the Linaro CI build service is now available for wider beta testing for L inaro engineering teams. If you are interested in trying out this service or if you have a kernel tree/defconfig that you would like to be continuously built on Linaro CI and tested in Linaro's LAVA lab, please get in touch with me and the infrastructure team, to discuss your steps to get started. Expect more updates and information from the Linaro CI front as we proceed. In the meantime visit the links below: 1. The Linaro CI Build service + https://ci.linaro.org 2. Details and background on the CI build service and how to request a new job + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI 3. The list of the existing Kernel CI builds that are currently built and tested on daily basis can be found at + https://ci.linaro.org/jenkins/view/All%20CI/ 4. Daily tracking your Kernel CI build results is explained here + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI#Monitoring_Build_F… 5. Daily tracking your Kernel CI runtime results is explained there + https://wiki.linaro.org/Platform/Infrastructure/LinaroCI#Finding_Test_Resul… 6. Future development ideas for the service + https://launchpad.net/linaro-ci/+milestone/backlog The 11.09 release is just a first step and more exciting and advanced continuous integration features are on their way. Linaro CI has already started showing results by finding bugs during our development/setup phase of Linaro CI build service. Visit our backlog milestone [6] in launchpad to get an up to date overview of ideas and deliverables in our planning pipeline. Here some samples of topics we discussed: 1. Extend the kernel CI effort by adopting further defconfigs and tracked trees and verification of the kernel builds on different kinds of boards in the LAVA lab. 2. Develop and host a one stop place for kernel CI tracking on LAVA dashboard, where engineers can continuously monitor their components for build and runtime failures. 3. Add support for adhoc kernel builds. This will allow kernel tree maintainers to try out pull requests and local developments in LAVA using a simple one time submit feature. 4. Improve CI support for downstream kernel maintainers (e.g. ubuntu, android). The goal is to make continuous downstream merging and integration of highly active upstream repositories very easy and efficient. The beginning of many milestones has just begin with a small step and your feedback will be of immense value in achieving the future milestones.

by Michael Opdenacker

Hi Mattias, FYI, a user is reporting an issue with l-a-m-c on http://ask.linaro.org/questions/191/linaro-image-tools I can't reproduce the problem, and I didn't find any bug in LP matching the error message, but I guess your team should be able to help this guy.

[Patch v4 08/11] Touch: DA9052 touchscreen driver

by ashishj3

This driver add support for DA9052 4-wire resistive ADC interfaced touchscreen controller. DA9052 is a MFD therefore this driver depends on DA9052 core driver for core functionalities.

Porter boxes offline 26/27 September

by James Westby

Hi, IS would like to upgrade the porter boxes from maverick to natty, which should make them more stable. This will require a reboot, and the upgrade may cause issues for some tasks, so please be aware and plan accordingly. The plan is to start with jenipapo at 1900UTC on Sept 26. The others (guinep, habitat) will be done in the hours following that, or starting at the same time on Sept 27 if they can't all be done in the first block. Thanks, James

Making it easier for Linaro users to help themselves

by Dave Martin

Hi all, Over recent months I've had a steady stream of comments from external people trying to use the Linaro deliverables about the difficulty of getting started, understanding what Linaro produces and how to use it. My experience with supporting users is that using and making sense of the linaro output is often not nearly as easy as we would like to believe. Part of the problem seems to be that we may not do a good job of passing on the knowledge and understanding necessary to allow users to help themselves. Is it worth a session at Linaro Connect to discuss how we could improve the situation? This probably falls in the "community" area. Key things to discuss might be: * identifying and understanding our audience * providing the "missing manual" (what knowledge do we tend to assume in linaro that our audience may lack) * wiki ownership and maintenance (how do we _manage_ the information we produce to maximise its relevance and usefulness) (This includes identifying stale/obsolete information, removing duplicates and providing useful indices, contents lists and introductory material.) Ideally, we should get some users external to linaro to attend and/or provide input. Cheers ---Dave

Reboot not working with the newly built upstream custom kernel

by Deepti Kalakeri

Hello, I am trying to build the upstream kernel like linux-linaro-3.0, linux(linus), linux-next, linux-arm-soc for next builds with omap2plus defconfig, Create a kernel debian package and use this debian package to verify the build. The builds are enabled with ext3 file system. The scripts that is used to build the kernel for example is http://bazaar.launchpad.net/~linaro-infrastructure/linaro-ci/lci-build-tool… . The builddeb used contains modifications submitted to work for cross compilation and the changes are available at http://permalink.gmane.org/gmane.linux.linaro.devel/7443. Other than that there is no hand made changes to any files. An example hwpack that I created using the linaro-hwpack-replace can be downloaded from http://ci.linaro.org/kernel_hwpack/panda/hwpack_linaro-panda_20110927-0741_… . This consists of the kernel debian package built from linux-linaro-3.0 with omap2 defconfig to work on a panda board. [PS: linaro-hwpack-replace which is part of the linaro-image-tools is a tool that replaces the old kernel debian package in a given hwpack with the supplied kernel debian package ] I see that the kernel builds successfully, and the hwpack containing this newly built kernel debian package boots fine on the boards, but it fails to execute the reboot command and it hangs with the following message: ################################################################# The system is going down for reboot NOW! root@linaro-nano:~# init: tty4 main process (3205) killed by TERM signal init: tty5 main process (3211) killed by TERM signal init: auto-serial-console main process (3213) killed by TERM signal init: tty2 main process (3215) killed by TERM signal init: tty3 main process (3218) killed by TERM signal init: tty6 main process (3224) killed by TERM signal init: openvt main process (3276) killed by TERM signal init: plymouth-upstart-bridge main process (3341) terminated with status 1 [ OK ]ing all remaining processes to terminate...
