Switch to ubuntu-build.linaro.org

by James Westby

Hi Fathi, Given the results of last week's weekly testing, do you think we should now flip the switch to move to using the images built by ubuntu-build.linaro.org (offspring.linaro.org as was)? If not, what are the blockers to doing so? Thanks, James

[ACTIVITY] OCTO status report - wk25.2011 (20110620-20110624)

by Ilias Biris

https://wiki.linaro.org/OfficeofCTO/Status/2011-06-21 == Highlights == - The Memory Management group met on #linaro-mm-sig IRC channel on 20110622. A summary of the meeting: * Most of the discussion revolved around the large physical allocation support (aka CMA) - specifically on the CMA areas initialization, allocations being in a specific area (memory bank), handling device specific attributes. * Towards the end of the meeting the discussion also touched on dma-mapping API status, as well as the participation to Linaro Connect. There are already 5 V4L2 developers interested in collocating a V4L2 brainstorming session with Linaro Connect. there might be a 6th one - ARMHF * Java is fixed - at least gcj seems to work. However immediately after that ecj started complaining. Konstantinos has nevertheless built a lot of packages for armhf - next step is to bootstrap openjdk * kde4libs has been failing lately, leading to not being able to have kde armhf packages ready. This was pinpointed to be due to qt4 atomics being broken on armhf, missing the patch from Ubuntu, so kde packages are now getting fixed * Debian has/is just undergoing a huge number of transitions now, and for debian-ports the team has to act on those manually (status is in http://www.debian-ports.org/~iwamatsu/transition/) - Device tree: Grant Likely has been working on bug https://bugs.launchpad.net/bugs/707047 (Only half of RAM useable when using Device Tree on Panda board). Grant is also coordinating the efforts for the Linaro Connect discussions related to device tree and boot architecture. - Boot architecture: Loïc Minier has started a discussion on the boot-architecture mailing list (see http://lists.linaro.org/pipermail/boot-architecture/2011-June/000016.html) - trying to create a reasonable use case which 'expresses the concept of "modules" that the boot architecture would cover'. == Upcoming Deliverables == * Expected to close some documentation work items for ARMHF and Boot Architecture during week 26 * Bootable SD card images for armhf, for the efikas, pandaboard, trimslice, should be uploaded during week 26 * ARMHF initial set of benchmarks should start appearing during week 26 == Miscellaneous == David Rusling back from holiday Konstantinos Margaritis is back from the Genesi sprint US trip -- Ilias Biris, Aallonkohina 2D 19, 02320 Espoo, Finland Tel: +358 50 4839608 (mobile) Email: ilias dot biris at linaro dot org Skype: ilias_biris

[ACTIVITY] Graphics WG status - wk25.2011 (20110620-20110624)

by Ilias Biris

https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/WeeklyReport == Highlights: * glcompbench and glmark2 have been released on 20110627 * unity-gles tarball on its way for the milestone release - getting ironed out as this is written * Last week's Graphics meeting was replaced by the meeting of the Memory Management group which took place on #linaro-mm-sig IRC channel on 20110622. There is more detailed information on the linaro-mm-sig meeting wiki page (https://wiki.linaro.org/OfficeofCTO/MemoryManagement/Notes/2011-06-22). Also don't miss to read the LWN article on Contiguous Memory Allocation : http://lwn.net/Articles/447405/ == Upcoming Deliverables: Planned content for the 11.07 release. == Risks / Issues: This was discussed together with Jesse Barker and Kurt Taylor from MMWG: related to Android released content from the graphics WG, we would need some guidance and support. Specifically having someone from the Android team guide our integration tasks, and perhaps set up a regular sync-up about Android integration would be beneficial.

by Ilias Biris

https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Highlights: Approaching the public plans review - blueprints are being created by the team. 5 TRs will be the work focus: - OpenMAX Integration - Userspace UMM - Codec optimization - NEON optimization forum - Audio integration It was decided that due to time shortage because of the planning, the work to release libjpeg-turbo for Android during 11.07 would not be feasible Also in discussions during this week, with Jesse Barker and Kurt Taylor, it was identified that we would need some guidance and support related to Android deliverables. Specifically having someone from the Android team guide our integration tasks, and perhaps set up a regular sync-up about Android integration would be beneficial.
