[Announce] Linaro Kernel 2011.05-2.6.38 Snapshot Released

by Deepak Saxena

The Linaro Kernel Working Group (KWG) is excited to announce the availability our May 2011 development snapshot: linux-linaro-11.05-2.6.38 This is the first of a new monthly series of development snapshots from the KWG that will provide a way for developers to work with the Linaro kernels without needing to follow the git tree on a daily basis. As the word "snapshot" implies, these are meant as development kernels and have not been fully validated. You should expect issues and to help us deliver a better kernel in the future, you should file bugs in Launchpad at https://bugs.launchpad.net/linux-linaro. The source tarball is available at: https://launchpad.net/linux-linaro/11.05/11.05-final/+download/linux-linaro… The kernel sources can also be accessed using git at: git://git.linaro.org/kernel/linux-linaro-2.6.38.git tag: linaro-11.05-2.6.38 A pre-packaged kernel for OMAP boards is available at: https://launchpad.net/~linaro-maintainers/+archive/kernel/+files/linux-imag… This snapshot is based on the 2.6.38.7 stable kernel with a number of changes developed by Linaro and integrated from upstream trees including the 2.6.39, OMAP, and Power Management trees to name a few. The changes from 2.6.38.7 include: * Initial Device Tree support for MX51, MX53, Overo, SMDKV310, Beagle, IGEPv2/v3, Panda, Tegra, and Versatile boards. This support allows memory size and board type to be passed via the Device Tree. * The ARM kprobes code has been updated to correctly handle a number of instructions that did not previously work and to work on kernels w/o frame pointers. * The coredump code has been updated so you can now analyze VFP register state using GDB. Using this feature requires the upstream GDB trunk tree or the Linaro snapshot available from https://launchpad.net/gdb-linaro/+download * CPUIDLE support for Samsung Orion has been added, allowing for longer battery life on platforms based on this chipset. * Experimental support for LTTng on ARM, allowing developers to perform deep analysis of system state transitions. See http://lttng.org/ for more information on using LTTng. A full changelog against 2.6.38.7 is available at: https://launchpad.net/linux-linaro/11.05/11.05-final/+download/CHANGELOG-li… High Priority Known Issues: * The combination of a device-tree enabled kernel and and Linaro's 2011-03 u-boot will make WiFi and HDMI unuseable on the IGEP board. (LP #768680) * imx51 randomly truncates serial input at 31 characters (LP #754254) * OMAP Beagle C4: kernel does not reliably find SD card on boot (LP #712175) * wl12** driver causes networking to hang on ubuntu-desktop image (LP #785739) * Only half of RAM useable when using Device Tree on Panda board (LP #707047) Mailing list: http://lists.linaro.org/mailman/listinfo/linaro-dev Questions? https://ask.linaro.org/

Android image goes into console suspend loop on Panda

by Mattias Backman

Hi, I'm sorry to send this to all, but there are no test cases on qatracker to report this on and it seems urgent. A little while after booting the latest android images on my Panda it goes into an endless loop, outputting this: pm_op(): platform_pm_suspend+0x0/0x9c returns -95 PM: Device kim failed to suspend: error -95 PM: Some devices failed to suspend PM: resume of devices complete after 476.470 msecs Restarting tasks ... done. suspend: exit suspend, ret = -95 (2000-01-01 00:01:20.662933350 UTC) PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.02 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.02 seconds) done. Suspending console(s) (use no_console_suspend to debug) Complete log attached. Thanks, Mattias

[CALL FOR TESTING] Linaro 11.05 Candidate

by Fathi Boudra

Hi, In preparation for the release of Linaro 11.05 images on 2011-05-28, a suitable candidate has been selected for testing. The release is expected to be tested heavily and provide the most stable and feature-rich images to date this cycle. If you have supported hardware, as found at: http://releases.linaro.org/platform/linaro-n/hwpacks/latest/ please help our initiative by testing the official Linaro Evaluation Build (LEB): Ubuntu Desktop: http://releases.linaro.org/platform/linaro-n/ubuntu-desktop/latest/ Android: http://releases.linaro.org/platform/linaro-n/android/latest/ and our Developer images: Nano: http://releases.linaro.org/platform/linaro-n/nano/latest/ ALIP: http://releases.linaro.org/platform/linaro-n/alip/latest/ Developer: http://releases.linaro.org/platform/linaro-n/developer/latest/ As a side note, hwpacks that have an -lt- in their name are outputs from the Linaro Landing teams, using some of their components. Make your way to: https://wiki.linaro.org/Cycles/MilestoneBuilds For an explanation of how to test and submit your results to the QA tracker at: http://qatracker.linaro.org For an explanation of how to use the qatracker please see: https://wiki.linaro.org/QA/QATracker Issues ====== [Bug 788765] linaro-image-tools bootargs broke panda LEB in revision 342 linaro-media-create generates a boot.scr that contains too many arguments to "setenv bootargs". To workaround the issue until next l-i-t release, please use: lp:~james-w/linaro-image-tools/fix-panda [Bug XXXXXX] Vexpress hardware pack 20110526 failed to build. Please use: hwpack_linaro-vexpress_20110524-0_armel_supported.tar.gz Cheers, Fathi -- Linaro Release Manager | Platform Project Manager

proposal for reorganization of releases.linaro.org hierarchy

by Fathi Boudra

Hi, Here's the following rationale: 1. as a user, I would like to easily find the released Linaro components: * Linaro Evaluation Build (Android and Ubuntu LEB) * Tools (linaro-image-tools) * Working Groups (kernel, u-boot, gcc, gdb, qemu, powerdebug, powertop, etc...) 2. as a user, I would like to download the release for my ${board} in one central place. 3. as a release manager on the road to monthly releases, I would like to adjust the current layout to match the release process. The current layout has some issues: - a user should go through several paths to get a rootfs and a hardware pack. - a user should go through several websites to find Linaro goods (releases.l.o, launchpad.net) - newcomers like Android doesn't fit well - every team has a different release process To resolve these user stories, we came up with 2 layouts proposal. Please, see the document attached. Feebdacks/suggestions on the proposals are welcome! Note: we planned to start with platform directory only. The working-groups could come later when we agree on the approach. Cheers, Fathi -- Linaro Release Manager | Platform Project Manager

Boot sanity testing of release candidate kernel

by Deepak Saxena

Hi all, The Kernel Working Group is getting ready to release the first of our new monthly development snapshot in a few days and we would like folks to do some quick sanity boot testing on their boards. Please grab or update the kernel from git://git.linaro.org/kernel/linux-linaro-2.6.38.git, and checkout the linaro-11.05-2.6.38 tag (which happens to be same as master at this moment) and give it a quick spin. Note that this is just the stock Linaro kernel and does not include any binary graphics drivers or other bits provided by Linaro's landing team kernels, so we just need the basic build and boot tested along with some simple testing of devices that can be used w/o extra drivers. Thanks! ~Deepak

[PATCH v5 0/2] SMDKV310 Board Support

by Chander Kashyap

Hi, This patchset adds support for a new board SMDKV310, based on S5PV310 SOC. This SOC is very similar to S5PC210 SOC, hence we are re-using this SOC code. Specific changes in patch versions are mentioned in specific patch files.

Blueprint dilemma: validation website vs dashboard improvements

by Zygmunt Krynicki

Hi guys. After looking hard at those blueprints and our discussions during UDS I'm getting this impression that the line between the two is blurred. It would significantly to frame the problem help if we could determine the architecture of "validation website" and how it differs from "lava" (especially after we did lava-server), where it ends up being (which project?) and so on. Best regards ZK

http git access?

by Dirk Behme

Hi, would it be possible to access the projects hosted in the git repository [1] using the http protocol? E.g. like with git.kernel.org? I know it's a pain, but some people sitting behind a firewall don't have any other option. Many thanks! Dirk [1] http://git.linaro.org/gitweb
