From: benjamin gaignard <benjamin.gaignard(a)linaro.org> The goal of those patches is to allow ION clients (drivers or userland applications) to use Contiguous Memory Allocator (CMA).

Organizing series and milestones based on quarters

by Zach Pfeffer

All, I recently reorganized my series and milestones to reflect quarters: https://launchpad.net/linaro-android I also filed milestones for the connects so that I can easily find the sessions I had.

Device trees are now supported in Android builds, can iMX6 use this?

by Jon Medhurst (Tixy)

Hi Bernhard I added support for device trees in this commit: http://review.android.git.linaro.org/#change,1359 Is there any reason iMX6 can't make use of this rather than having a custom make recipe in tasks/kernel.mk? I believe that iMX6 just needs to add the following line to its BoardConfig.mk ... DEVICE_TREES := imx6q-sabrelite:board.dtb -- Tixy

Improvements to Android Build errors separation (and NOT BUILT status)

by Paul Sokolovsky

Hello, One of the issues with https://android-build.linaro.org/ is that, if build fails, it's not easy to tell if it happened because of compilation error ("real" failure) or due to non-deterministic error with setting up infrastructure for build (e.g. during source checkout). The latter not so uncommon due to vast source size of Android and complexity of cloud infrastructure. This became especially problematic with start of automated CI loop, where it leads to false negatives when doing pre-merge testing. Improving this situation was subject of few blueprints in which Infrastructure team worked, and recently, a solution was deployed. With it, if a build fails due to non-deterministic infrastructure error, it will get status of "NOT BUILT", meaning that a build never actually got to compilation phase. Suggested action in such case is to retry. Please note that Jenkins there is some inconsistency within the Jenkins itself regarding NOT BUILT status - "Pending" is used as a display name in places, and the same gray icon used as for ABORTED builds. So, please keep that in mind, or yet better use Build Frontend. Unfortunately, even short weekend testing showed that error separation achieved is not ideal (folks who participated in Connect Q4.11 session dedicated to this, may remember that I said that it would take adding AI to do that properly ;-) ). In particular, if there was an issue with manifest file (essentially, an error in Android source code), it will be reported as NOT BUILT instead of FAILED. Here's example of such build: https://android-build.linaro.org/jenkins/job/linaro-android_panda-ics-gcc44… Opposite miscategorization may also happen: very early infra error may be reported as FAILED instead of NOT BUILT. Example: https://android-build.linaro.org/jenkins/job/linaro-android_panda-ics-gcc46… So, Infrastructure team will continue to work on improving reliability of builds, but in the meantime please keep looking in the build logs for actual cause of the failure (feel free to report unexpected build status to https://bugs.launchpad.net/linaro-android-infrastructure) -- Best Regards, Paul 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

Switching the builds to the tip toolchain

by Zach Pfeffer

Abhishek, The first thing to do each cycle is to switch the builds to the tip toolchain from the release toolchain. Do this: 1. Go to https://android-build.linaro.org/jenkins/ look for linaro-android_toolchain-4.6-bzr 2. Click on: "Last successful build (<build number>)" Copy the link to "android-toolchain-eabi-4.6-daily-linux-x86.tar.bz2" Something like: https://android-build.linaro.org/jenkins/view/Toolchain/job/linaro-android_… 3. Goto android-build: For these builds (enter 12.02 in the Search: field) https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-… https://android-build.linaro.org/builds/~linaro-android/vexpress-ics-gcc46-… https://android-build.linaro.org/builds/~linaro-android/imx53-ics-gcc46-fre… https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc46-sa… https://android-build.linaro.org/builds/~linaro-android/imx6-ics-gcc46-free… https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc46-til… https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc46-kwg… https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc46-oma… For each build change: TOOLCHAIN_URL= ...to the link you just found above. Kick off all the builds, add the build to the test spreadsheet, smoketest each one, and report any issues. Sound good? We'll automate this soon, once we get the configs in git. -- 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
