First (semi-)working Linaro JellyBean build

by Bernhard Rosenkränzer

Hi, I've just committed the code needed to build an initial Linaro JellyBean version (buildable with the Linaro gcc 4.7 compiler): repo init -u git://android.git.linaro.org/platform/manifest.git -b linaro_android_4.1.1 repo sync Currently the build supports only the Galaxy Nexus - didn't want to run into trouble with potentially incompatible binary blobs before knowing the rest of the system is working. Support for our normally supported boards will be added over the next couple of days. Optimizations that currently aren't on the 4.1 branch will also be restored in the next couple of days. There's also 2 problems we need to fix quickly: E/WVMExtractor( 126): Failed to open libwvm.so entries showing up in logcat (a quick grep indicates nothing seems to build libwvm - neither in our tree nor in AOSP) and I/v8 ( 1293): ERROR: Binary compiled with -mfloat-abi=hard but without -DUSE_EABI_HARDFLOAT (we don't actually use hardfloat (yet), so chances are the check for hardfloat goes wrong with gcc 4.7.x) The camera isn't working, but that's not a high priority issue given the Galaxy Nexus is not a device we're supporting officially. Of course our gerrit is always happy to receive patches for these and other issues. ;) ttyl bero

[IMPORTANT] Please clean up personal and older official Android builds

by Paul Sokolovsky

Hello, We keep having cases of out of disk space, latest we had is https://bugs.launchpad.net/linaro-android-infrastructure/+bug/1055546 . The reason this happens so often is that Jenkins has a broken build expiration process - it is applied to jobs which are actually built. If a job is left unattended, its builds will stay forever. This is long-standing known issue, and I manually deleted stale builds in this case, while queuing need to write a script for that, which I'm going to start with now. To remind, we have following build retention policy: 1) Release builds stay forever 2) Official daily builds kept for 3 months 3) Personal builds kept for 1 month With new expiration script to be developed, many builds will be "suddenly" (but in full accordance with the policy above) gone. So, I would like to ask all Android developers to look thru their builds to check if you need anything old (and preserve it somewhere else then). Zach, Fathi, Alexander, can you please do the same for old official builds. For example, https://android-build.linaro.org/jenkins/view/Official%20builds/job/linaro-… would be gone completely. In addition to the above, the issue we may have that there're lot of empty personal jobs piled up (with builds removed per the policy above). They clutter view largely, for example, Bero has 10 such jobs, Zach - 8, etc. Do you still need them? Otherwise, I'd propose to add another clause to the policy and remove such empty jobs if not updated within last 3 months. Let me know what you think.

benchmark of libjpeg62

by aigo6＠mail.ustc.edu.cn

Dear linaro, I follow the page https://wiki.linaro.org/ChaoYang/Sandbox/tjbench to use the benchmark of libjpeg62 in my computer ,which operation system is Ubuntu 11.10. Run the " tjbench /mnt/mytmpfs/nightshot_iso_100.ppm 95 -rgb -quiet scale 1/2 tjbench /mnt/mytmpfs/nightshot_iso_100.ppm 95 -rgb " in terminal ,result tell me it is correct. But when I use " tjbench-libjpeg62 /mnt/mytmpfs/nightshot_iso_100.ppm 95 -rgb -quiet scale 1/2 tjbench-libjpeg62 /mnt/mytmpfs/nightshot_iso_100.ppm 95 -rgb " , system tell me it can not find "tjbench-libjpeg62" ,did libjpeg-turbo-1.2.1 only can be used in android ? Best wishes.

Linaro Android - 12.09 Release Test Result Summary for Calendar Week 39

by amit khare

Hi, Calendar Week 39: We had Linaro android 12.09 release this week. Here is test result summary on following boards: 1) ARM Versatile Express A9 2) ST-Ericsson Snowball Board 3) TI Panda Board 4430 4) TI Panda Board 4460 5) Samsung Origen Board *Synopsis: This week, Linaro Image Tool 12.09 version was used to flash SD-card for testing. Installation instructions are missing on all the android build pages. Glmark2 can now be run successfully on Snowball and Panda too. "Deadlock" error no longer exists on Vexpress-a9 board and for some reason "clock" application fails on Origen board. * Detail Report for all the boards: *1. ARM Versatile Express A9 - Android (Column I)* Test Results: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadExQd… Installation instruction is missing. "DEADLOCK" error has been eliminated. Device Tree is still unavailable although the blob files now can be loaded successfully. This is an expected result since it's caused by a UEFI defect as Ryan mentioned before. Although "Calendar" app can be launched and shown successfully, bug 1057208 actually makes it unusable - failed to add any event item. All other features remain same status as previous week. *2) ST-Ericsson Snowball Board - Android(Column I)* Test Results: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadEF1N… Install instruction missing on the build page. With 12.09 release "GLMARK2" test case is working which used to fail earlier. *3) TI Panda Board 4430 - Android(Column Z)* * * Test Results: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadGVWd… On Panda board hardware graphics acceleration, glmark2 and 0xbench works fine with 12.09 release build. *4) TI Panda Board 4460(Column Q)* Test Results: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadGVWd… Test results same as 4430. *5) Samsung Origen Board(Column D)* Test Results: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AkxwyUNxNaAadDRDV… Installation instruction is missing. The other features remain the same status as last week, except the "Clock" app. More details can be found in bug 1032703. Note - For the previous week (Calendar week 38) summary, please refer to attachment. Thanks, Amit khare <amit.khare(a)linaro.org> QA Services - Linaro Platform http://wiki.linaro.org/Platform/QA

Work around for building Linaro Android 12.08

by Zach Pfeffer

For people trying to build Linaro Android 12.08 there's an issue with an unknown reference in powertop2.0. Here's what to do: cd android edit .repo/manifest.xml Find: <project groups="path:external/powertop,name:tools/powertop-2.0" name="tools/powertop-2.0" path="exter\ nal/powertop" remote="linaro-other" revision="c80f55d9d1b823b7f6ff447eefc8a6ba04b939c4"/> ...and remove the line. Then cp .repo/manifest.xml ../ cd .. rm -rf android/ edit linaro_android_build_cmds.sh and change curl -k http://snapshots.linaro.org/android/~linaro-android/vexpress-jb-gcc47-armlt… > .repo/manifest.xml to cp ../manifest.xml .repo/ and rerun linaro_android_build_cmds.sh You can also take a tip build which is not susceptible to this problem. Tip builds that have been booted are listed at: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AnpUtxWjZbP9dGg0d… If you still get errors after this, then its a general git timeout error. Just delete the android/ directory and start again or cd android/; repo ./sync -- 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

the optimization of bionic libc

by 牟刚

Hi everybody, It’s reported that linaro android 4.0.4 boost performance by up to 100% over AOSP because of the optimization of bionic libc, especially the functions memchr( ), strlen( ) and so on. But I found that there is no difference between linaro source code and AOSP source code in these functions. Is there anything wrong? Thanks & Best Regards! 牟刚 Actions Semiconductor Co.,Ltd Tel: +86-756-3392353 ext.3103 Fax: +86-756-3392251 Email: mugang(a)actions-semi.com HTTP://www.actions-semi.com

Most open source board / best Android board

by Diego

Hi everybody, I'm looking for a board to hack on Android 4. I've seen that there are several ARM boards with Android community support: Origen, PandaBoard, Snowball, etc. I'm interested in knowing which one is the most "open source" one, that is to say, which one relies on the least number of proprietary drivers (es. PandaBoard needs PowerVR binary driver for accelerated graphics, while the Snowball board Mali 400 GPU has an experimental open source driver). I'm also interested in which one has the best support for Android, in terms of features supported (best Android port). Thank you for any suggestion you'll give me! Regards, Diego
