what does this status in jenkins build q mean

by John Rigby

I see this pop up with hovering over some kernel ci jobs in build queue: 'All nodes of label "kernel_cloud" are offline' Does this mean something is broken or will it recover on its own? --john

Closing out the iMX Android platform....for now

by Zach Pfeffer

Hey team, We've been asked by Alexander and Joe to focus on other targets for awhile. This means that the iMX53 and iMX6 work that we've done will stay in its current state. Practically this means: 1. No updates to iMX based manifest (we'll delete the MX manifests from linaro_android_4.0.4 to make this clean) 2. No bug fixes 3. No daily builds The builds we currently have will stick around. Anyhow, this will allow us to refocus on less, which is good. I'd really like to thank Bero, who's awesome work on the MX allowed this board to run in the first place and who's work keeping it going has be extremely valuable to Linaro. Close out tasks are tracked at: https://blueprints.launchpad.net/linaro-android/+spec/close-out-imx -- Zach Pfeffer Android Platform Team Lead, 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

running an armel image on 12.04

by Scott Douglass

Hi, I'm trying to run an old armel image on 12.04 on Snowball. It doesn't run because there's no armel support; starting with a missing /lib/ld-linux.so.3 How can I add armel support? I tried this: # dpkg --add-architecture armel dpkg: error: unknown option --add-architecture # apt-get update ; apt-get install dpkg [...] dpkg is already the newest version. # dpkg-query --show dpkg dpkg 1.16.1.2ubuntu7 Thanks for any pointers you can give me. -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

[Linaro Connect] Session about packaging Linaro components

by Marcin Juszkiewicz

Hi all. During Linaro Connect there will be a session [1] about packaging tools and other components produced by Linaro teams. Goals: - Review the current set of components/projects create and maintained by Linaro - Identify the ones that are not yet part of Ubuntu and Ubuntu LEB - Discuss how to make the Linaro changes upstream at the distro-level as soon they are updated I want to get Linaro to the point where most of our tools will be available in Debian and Ubuntu distributions instead of random set of PPAs. Whom I would like to see there? Everyone who has written any packaged (or not yet) tool useful for other developers. Nevermind is it host or target, native or cross tool. 1. http://summit.linaro.org/lcq2-12/meeting/20859/review-the-missing-packages-…

Optimized kernel memcpy/memset

by Christian Robottom Reis

Hey there, I was asked today in the board meeting about the use of NEON routines in the kernel; I said we had looked into this but hadn't done it because a) it wasn't conclusively better and b) if better, it would need to be done conditionally per-platform. But I wanted to double-check that's actually true (and I'm copying Vijay to keep me honest). I have some references: http://lists.linaro.org/pipermail/linaro-toolchain/2011-January/000722.html http://groups.google.com/group/beagleboard/browse_thread/thread/12c7bd415fb… http://www.spinics.net/lists/arm-kernel/msg106503.html http://dev.gentoo.org/~armin76/arm/memcpy-neon_result.txt https://wiki.linaro.org/WorkingGroups/ToolChain/Benchmarks/InitialMemcpy?hi… https://wiki.linaro.org/WorkingGroups/ToolChain/StringRoutines?highlight=%2… Incidentally, this ties into the question sent earlier this week which had to do with Nico's work item in: https://blueprints.launchpad.net/linux-linaro/+spec/other-kernel-thumb2 Which IIRC Nico says probably isn't worth it, right? -- Christian Robottom Reis | [+55] 16 9112 6430 | http://launchpad.net/~kiko Linaro Engineering VP | [ +1] 612 216 4935 | http://async.com.br/~kiko

[ANNOUNCE] New boot loader on Snowball

by Mathieu Poirier

All, In our ongoing effort to move to an upstream-supported code base and booting the snowball with a device tree (DT) I have change the boot loader in the following android builds [1][2][3] to u-boot-linaro-stable [4]. Once the linaro-uboot is installed in a system it won't be able to boot images that were created at an earlier time. Say that build #500 has the new linaro-uboot and the image has been installed on the emmc. Once powered this uboot will not be able to boot build #499 that is installed on the mmc. To fix the problem, simply install build #500 on the mmc. This is because the mmc commands in the IK-uboot and the linaro-uboot differ. To install the linaro-uboot you *must* use the latest android-linaro-media-create found here [5] until the changes get merged in the official repository [6]. Something like: $ bzr branch lp:~mathieu.poirier/linaro-image-tools/linaro-image-tools Last but not least, the linaro-uboot is currently not able to save the environment variable block to the emmc card. That work is ongoing and the functionality expected to be part of 12.05. Find me on IRC if you have any questions. Regards, Mathieu.

can I read Overo's madc registers...??

by Sudhangathan B S

I did a number of searches and found that in the recent kernels the twl4030-madc module has been made upstream. And I found this link: http://wiki.gumstix.org/index.php?title=ADC_overo_2.6.39%2B as I followed it, I couldn't find the directories mentioned therein.. The most relevant thing I found in Linaro-Alip/Nano file system was the /sys/class/i2c-adapter/ folder. Now i'm into the wild and searching for the file I need, so that I can read the ADC values. Any help meanwhile....??? --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 --------------------------------- terms: twl4030-madc tps65950 hwmon madc driver sys class i2c-adapter

[PATCH 0/2] ARM: DAVINCI: cpuidle - cleanups

by Daniel Lezcano

These couple of patches use the new cpuidle core api to refactor some part of the code. The first one removes the state count initialization as it is done from the cpuidle core and the second one use the new API and removes the ops. The patchset is based on Lenb's tree on top of Robert Lee cpuidle consolidation work. I don't have this board, I was not able to test these patches.
