Shared hardware

by Michael Hope

We're a bit lacking in hardware at the moment. I've gone through my setup, given it a bit of a polish, and made the following available to the outside world: * pavo1 - a BeagelBoard clone with a hard disk, suitable for running long jobs * pavo2 - a BragleBoard clone * orion - an Atom N450 based netbook * scorpius - an AMD Phenom based machine, useful as a distcc host Please contact me if you'd like access. Both pavo1 and orion are suitable for running long jobs on. More details are available at https://wiki.linaro.org/WorkingGroups/ToolChain/Hardware. These will shift into the data centre in the future but it's nice to have them available now. -- Michael

by Nicolas Pitre

I just made available a new Linaro kernel merge result at the following location: http://git.linaro.org/?p=linux/arm_next.git;a=summary The process we're experimenting at the moment for the production of this kernel is described on this page: https://wiki.ubuntu.com/Specs/M/ARMKernelVersionAlignment This is the merge result from the following branches: Linus' tree at v2.6.35-rc5-43-gf469461 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 RMK's "devel" branch at commit 414a0eac http://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm.git Catalin Marinas' "rebased" branch at commit 4298370d git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git Will Deacon's "for-linaro" branch at commit 1d4a8e2c git://repo.or.cz/linux-2.6/linux-wd.git Uwe Kleine-König's "arm/booting" branch at commit e69edc79 git://git.pengutronix.de/git/ukl/linux-2.6.git (this also contains patches from Eric Miao for automatic ZRELADDR) The Ubuntu Maverick branch has been dropped per general request. This has been tagged with "linaro_merge_100716" and the tag message also has the above info. This is also available through the following gitweb link: http://git.linaro.org/gitweb?p=linux/arm_next.git;a=tag;h=linaro_merge_1007… The previous merge result is still available through the tag "linaro_merge_100712" for reference. Please contact me if you have any issue with this tree. Positive feedback is also fine! ;-) Nicolas

Kernel Consolidation WG - 2010-07-14 Meeting notes and activity report for last week

by Loïc Minier

Hey Please find below the minutes from yesterday's Kernel Consolidation Working Group meeting and the activity reports from previous week. You can find the full meeting notes at https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2010-07-… == Agenda == * Action items from last meeting. * mwaddel to code review the arm_next.git tree and check that all patches are present. * [DONE] mwaddel will try the kernel on the versatile board. * jk to report on progress of talking to Grant WRT upstreaming his patches. * [CARRY OVER] no response from Grant yet. * mwaddel to talk to ARM about device-tree work. * [DONE] * Jeremy to chat with Nicolas about documenting boot interface. * [DONE] some patches already produced. * npitre to find a way to expose the list of trees merged in arm_next.git via a wiki page. * [DONE] documented in the tag instead. * jcrigby to talk to slangasek about the list of kernel flavours to produce. * [CARRY OVER] jcrigby to talk face-to-face at the sprint. * amitk to report back the status on linux-omap's patches. * [CARRY OVER] amitk absent. * jcrigby to determine if versatile is still needed. * [CARRY OVER] jcrigby to talk face-to-face at the sprint. * lool to check that -fPIE support is currently enabled in the Linaro toolchain. * [DONE] http://lists.linaro.org/pipermail/linaro-dev/2010-July/000150.html * npitre and arnd to review ericm's single zImage patches. * [DONE] ongoing and doesn't need an action item. * ericm to send single zImage patches to russelking after they have been reviewed. * [DONE] patches are going to the public mailing lists. * jcrigby and lool to arrange a uboot specific call for interested team members. * [CARRY OVER] Arrange at the sprint - http://lists.linaro.org/pipermail/linaro-dev/2010-July/000149.html * Blueprint status. arm-m-using-device-tree-on-arm arm-m-kernel-version-alignment arm-m-missing-security-features arm-m-debugging-with-oprofile spec/kernel-maverick-arm-single-zimage arm-m-versatile-express-a9-enablement * Gathering ideas for face to face discussions / work items for the sprint * Personal work plan for the sprint * Plenaries * Meeting canceled for week of sprint === Action Points === * jk to report back on Grant Likely’s response to upstreaming patches * ericm to discuss with lool how to get more hardware. === Minutes === * lool on vacation today, short status call. daverusling asked about the status of the Ubuntu kernel patches in the Linaro tree after recent discussion on the mailing list. nico explained that they were not to be merged as the benefits of merging were small and individual patches could be merged at a later date. * mwaddel code reviewed arm_next.git and checked that required patches were present. He is checking versatile express with it now. * jk emailed Grant Likely to discuss the upstreaming on his patches, no response yet. * [ACTION] jk to report on progress of talking to Grant WRT upstreaming his patches * Matt talked to Lorenzo at ARM about device tree status. Based on jk’s work patches are not quite ready yet but are close. * jk pushed some patches on the boot interface. More work can be done face-to-face with nico at the sprint. nico mentioned that documentation is already there. Both considered this action done. * There was some discussion on where the list of trees merged in to the arm_next.git tree should be documented. nico included this information directly into a tag in the tree. The question was asked if a separate wiki page needed to also convey this information, the consensus was not due to the constantly updating nature and nicely seeing the documents history. * jcrigby has been producing omap and versatile kernel flavours, no others have been identified yet. jcrigby will talk to slangasek to determine if versatile is still needed and if other flavours should be added. This will be done face-to-face at the sprint. * eric forwarded some patches to upstream public mailing list for the single zImage blueprint. Consensus was that this work spans many weeks and isn’t a specific action item but should be monitored. === Blueprints === * jk had a bunch of patches around for debugging mapping for device tree’s and has been working on them this week. Good progress. Discussions with Grant about mainlining device-tree’s proved insightful. * jk also mentioned that he will be working on imx51 in the near future. * ericm said that there may be a need for pbuild hacks to allow multiple platforms to be built at once to help on the single zImage blueprint. Work is ongoing. * A lack of hardware is hampering progress at the moment as ericm only has one platform. * [ACTION] ericm to discuss with lool how to get more hardware. * dmart mentioned that the missing security features spec was waiting on kees but most items were either nearly complete or completed. * dmart went on to inform the group that work on oProfile by willdeacon was on track. * Work on the versatile express board by mwaddel is ongoing and lots have work items have been defined but mwaddel noted that once a booting kernel is available most work items will be quick to complete. * JamieBennett asked the group to fill in their personal goals for the sprint at https://wiki.linaro.org/Events/2010-07-PlatformSprint/KernelConsolidationWG and to suggest plenary topics. * There will be no meeting next week due to the face-to-face sprint. Activity reports from previous week: = Arnd Bergmann = == Getting started == * Built a qemu chroot for cross compiling * Research about ARM CPU families * Tried to set up Gumstix with uweigand * Looked at the kernel for my WM8505 tablet = Nicolas Pitre = * Reviewed some of Eric Miao's patches on the linux-arm-kernel list. * Reviewed Will Deacon's second round of patches to fix asm constraints for atomic ops on ARM. * Reviewed more of Uwe Kleine-König's Makefile cleanup patches and asked him to produce a pull request for RMK. I also intend to pull his patches into the arm-next tree. * Had another look at the DT patch series. Somehow I still am not as pleased with them as I would. Maybe I should take more time to study the generic DT docs and possibly come up with more concrete suggestions. * Discussed with Kees Cook about the issue I was having with the stack protector test module. Seems that it works only on array of chars only and not of all types. * Tryed to improve design in the OMAP hsmmc driver by discussing alternative solutions on the mailing lists where some new development were posted for review. The people involved seem to have agreed to change their code. * The usual mailing list monitoring and replying. * Prepared a Git pull request for the Orion/Kirkwood/Dove stuff I'm still maintaining for the next merge window. = Jeremy Kerr = == ARM == * device tree: rebased to gcl's new test-devicetree branch and rmk's updated master branch * device tree: implemented DT-pointer-in-r2 boot interface in ARM kernel boot code (r2-direct branch) * device tree: implemented DT-pointer-in-r2 boot interface in qemu (r2-direct branch) * device tree: maintenance on versatile branch * chased down versatile timer issues; problem has since been fixed in qemu * built a simple debug initramfs = Jamie Bennett = == General == * Spent much of Monday morning catching up with emails, wiki's and various other sources after my vacation. Furious wiki editing and tidy-up. Decided to unsubscribe from a few less read mailing lists to try to avoid the '' '3000-emails-sitting-in-my-inbox-after-vacation' ''syndrome. * Took on TLE (Technical Liaison Engineer) role to be ARM's technical point of contact. Extra workload at this stage should be manageable but will be reassessed at a later date. * Usual meetings, kernel consolidation minutes and associated wiki pages done. == Sprint Planning == * Lots of coordinating the Linaro sprint, answering peoples questions, arranging hardware to be available, making sure we have enough room and working with Anmar to take some tasks from him as he is on vacation next week. * Arranged with Stephen Doel to supply hardware for the sprint, recommended specific items which should arrive by Friday next week. == Blueprints and Releases == * Started discussions about how we can improve the blueprint/work item tracking. For next cycle I will propose some changes to make progress on work items much more transparent. * Prodded team members individually to ensure they are on top of their work items. There is a worrying amount of work still to do this cycle and keeping on top of this is essential. Some blueprints need more love than others so talked to the managers to ensure everything is still on track. * The Power Management and Toolchain work groups now have blueprints associated with them. These are not tracked with the main release burn-downs. Set up launchpad projects for each working group and worked with pitti to get the work-item tracker recognising the new projects. == Development == * Spent some time looking at the launchpad-work-item tracker project to try to understand how it can be hacked for our purposes. There are a few features I will be working on before next cycle to make the Linaro project easier to track. * Pushed 'members as groups' support to the work item tracker. Now projects with members who are actually groups can be tracked allowing 'meta-projects' to be created to track disparate projects all together. http://people.canonical.com/~pitti/workitems/maverick/arm-ubuntu.html is an example of one such meta-project which is set up to track the 3 Linaro groups progress. = Loïc Minier = * Reviewed Amit's power management WG plans * Tried out UBIFS on my sheevaplug, but couldn't get it to attach to mtd2 on boot, would only attach manually after boot * Built a maverick kernel for my beagleboard with the workaround for LP #591941 * Looked at ARM's Android patches for RealView; lack hardware to test them out, but I could try in QEMU Bye, -- Loïc Minier

I'm terrible with faces and worse with names. I couldn't resist knocking up a quick set of flash cards: http://wiki.seabright.co.nz/linaro-boo/ This is generated from the Engineeering Team wiki page by a simple Python script. Let me know if you want to be removed. -- Michael

[Linaro-dev] Removing Subject: prefix on mailing-lists

by Loïc Minier

Hey I don't quite like the [Linaro-foo] prefix which our mailing-list software adds to all emails' Subject: line. They clutter the subject to make filtering easier, but the list software also adds a List-Id header. Would anybody mind if we were to remove them? Thanks! -- Loïc Minier
