Jenkins and Ec2 plugin upgrade on Linaro CI [ ci.linaro.org]

by Deepti Kalakeri

Hello, I'd like to upgrade Jenkins on ci.linaro.org to align with the jenkins and ec2 plugin version on https://android-build.linaro.org/. ci.linaro.org currently runs on jenkins version 1.400 and ec2 plugin version 1.11, the versions available on https://android-build.linaro.org/ for jenkins is 1.419 and for ec2 plugin is 1.13. I would like to upgrade jenkins to 1.419 and ec2 plugin to 1.13 on ci.linaro.org as these versions have been in production for quite a long time on andriod build service and has undergone rigorous usage without any problems/issues. I reviewed changelog and see that the upgrade would not cause any problems. So, I'd propose to perform upgrade Indian Standard Time 11 am, Wednesday Oct 19th 2011. Please let me know if there're any concerns. -- Thanks and Regards, Deepti Infrastructure Team Member, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

[CALL FOR TESTING] Linaro 11.10 pre-release Oneiric based images

by David Zinman

Greetings, In preparation for the release of Linaro 11.10 images on 2011-10-27, our Linaro Ubuntu platform has been updated. It is now based on Ubuntu 11.10 (Oneiric). This call for testing is focused on the Oneiric based images. All primary development boards supported by Linaro Landing Teams have an Android staging image submitted and an Ubuntu LEB hwpack submitted. Note: Due to the early stage of the enablement, some images might not work. Note: Your feedback to this call for testing will provide the main source of data used by the Release Team to determine the user experience and hence is essential to this process. Linaro Evaluation Build (LEB) ============================= Please help our initiative by testing this month Linaro Evaluation Build (LEB) candidates for Android and Ubuntu: Android testing form: http://bit.ly/ojfwiC Ubuntu testing form: http://bit.ly/oVBcE9 * i.MX53 Quick Start: Android: http://bit.ly/nuaLOf Ubuntu: http://bit.ly/oEIrBF and http://bit.ly/ruTqHm * Origen: Android: http://bit.ly/nuttaQ Ubuntu: http://bit.ly/ojnEiI and http://bit.ly/ruTqHm * PandaBoard: Android: http://bit.ly/qcnxLd Ubuntu: http://bit.ly/rbmUIg and http://bit.ly/ruTqHm * Snowball: Android: http://bit.ly/nS5JtE Ubuntu: http://bit.ly/qT0Apd and http://bit.ly/ruTqHm Developers and Community Build ============================== On top of our officially supported Linaro Evaluation Build candidate images from above, the Linaro Platform Team is proud to also provide additional images and additional board support bits that were prepared by Linaro developers and community for a more specific target audience. Note that the Developers and Community bits are provided on a best-effort basis and in the hope that they can be useful. We release last reported known to be working images. If you want to try our LEB on one of the board support packs maintained by our community, please help and test by following the download and installation instructions included in the questionaire linked from above and your board hardware pack: * BeagleBoard: http://bit.ly/noPYwo and http://bit.ly/ruTqHm * BeagleBoard-xM: http://bit.ly/noPYwo and http://bit.ly/ruTqHm * EFIKA MX: http://bit.ly/qgyrOa and http://bit.ly/ruTqHm * IGEPv2: http://bit.ly/oEPPkX and http://bit.ly/ruTqHm * i.MX51 Babbage:http://bit.ly/qERcoq and http://bit.ly/ruTqHm * Overo: http://bit.ly/nbUGyO and http://bit.ly/ruTqHm * PandaBoard: http://bit.ly/ppFCPM and http://bit.ly/ruTqHm Resources ========= Note: Wonder what to download?

[ACTIVITY] MMWG status - wk 41.2011 (20111010-20111014)

by Ilias Biris

Status report with detail is in https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Last weekly meeting minutes: IRC logs linked in https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-10-11 == Highlights == - Investigation ongoing for pulseaudio + UCM: thread is in http://lists.linaro.org/pipermail/linaro-dev/2011-October/008160.html. An analysis is also put in the wiki at https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Specs/1111/Audi…. What is discussed in the list is the suggestion for improvements, ie modelling of UCM concepts onto PulseAudio concepts. Seems that some of the discussion will be taken during ELCE/LinuxCon/GstConf, next week, but unfortunately no MMWG members can be there. The discussion during Connect is now being set up - For LJT: https://wiki.linaro.org/TomGall/LibJpegTurbo contains benchmark data for https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-benchm…. There seems to be a difference between LJT on Ubuntu and LJT on Android in the order of about 25%. Investigation ongoing as to why + Also on LJT: Working for 565 support. Code is generally there, looking as to how to best generate / obtain test images slightly less than obvious. Item seems risky for 1110 - For the UMM side of work: video codecs working, re-rebasing omapdrm driver on latest linux-next and dss patches that are a dependency are going in for 3.2 so Rob will try to get the omapdrm driver in as well. Also work went on to get the camera board working on Panda this week. - Other work: looking into the LAVA requirements for setting up benchmarking tests for the codecs we have been working on - Ongoing discussion for the requirements for next cycle.

SCHED_MC dropped from ARM configs?

by John Stultz

Hey Amit, In updating our tree to 3.1, I noticed the SCHED_MC config option dropped out of the savedefconfig and it doesn't seem to be found in the arm Kconfig. Is that expected? Or are there out of tree patches that provide the SCHED_MC option for 3.1? thanks -john

[ACTIVITY] OCTO status report - wk41.2011 (20111010-20111014)

by Ilias Biris

Status report in more detail: https://wiki.linaro.org/OfficeofCTO/WeeklyReport Last meeting minutes: https://wiki.linaro.org/OfficeofCTO/2011-10-11 == Highlights == - Considering what would be the next catalyst area to open a path towards from OCTO + Platform architecture/UEFI/ACPI and its relation to the arm server area: what does it take to move on from the embedded marketplace to the commodity HW market place. What happens before the kernel is given a chance to run. + Better education on how to work with SMP especially on the application level. - ARMHF: runtime linker initial implementation ready to do some benchmarking with, to be improved later. Also the ARMHF build machines are now under DSA should start getting packages building soon. Still one blocking issue is lack of disk space from the central server (ftp master) for Debian + The HF archive is ready in the sense of having userspace parts which can be put together manually to create a rootfs, but we do not have the kernels in debian built for platforms other than i.mx51/3. - Boot Architecture / UEFI: Long term issue related to ACPI and UEFI processes: feedback is gauged from the Linux mailing lists (Grant initiated the discussion already) + For the short work items, they have been discussed and initial priorities set - focusing on support for zImage, usage of GPT for partition booting, exploration of ACPI issues among other items. Possibly will start some OCTO prototyping booting traditional and Android systems via UEFI + Based on the discussion the existing blueprints for Boot Architecture and UEFI will be revised accordingly https://blueprints.launchpad.net/linaro/+spec/linaro-kernel-o-bootarchitect… https://blueprints.launchpad.net/linaro/+spec/linaro-kernel-o-uefi - Other work: + Validation on SMP presentation (Invited lecture on validating parallel programs for China Linux Kernel developers conference), working on a whitepaper for ARM memory barriers and atomic operations. Ongoing full-up documentation of Linux's RCU implementation including also review of a user-level library that includes RCU and other concurrent algorithms (https://blueprints.launchpad.net/linaro-octo/+spec/linaro-octo-rcudocumenta…) -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

alsa ucm in pulseaudio

by Feng Wei

Hi Liam, Mark, Colin, and all, I study the codes in pulseaudio and alsa ucm patch recently, and create a page of my study result. I appreciate your feedback. The page is at https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Specs/1111/Audi…. Also if needed, I'm glad to contribute to the integration of alsa ucm in pulseaudio. Thank you. -- Wei.Feng (irc wei_feng) Linaro Multimedia Team Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
