This is a high level summary of LMG engineering activities for the 1/2 half of January 2015. I've compiled this information from the weekly status meetings that each sub team holds over irc. Errors are mine. This is an experiment and feedback is most welcome. Across the board the team is very busy with Connect prep work including demos and presentations. LMG will have a lightning session as well as 5 presenting sessions. The Android team has also put together several conference proposals for the Android Builders Summit in March. Android ====== Bero Rosenkränzer YongQin Liu Peter Pan Yanbin Fang Xavier Xsu Bero has been building, booting and measuring Android with Clang 3.6, gcc 4.9 and gcc 5.0 YongQin has put together the Java App benchmark report Peter and Bero have been looking at L memory consumption and has put together a wiki page of information. Peter has also been working on enablement of lunch for dev/linaro Xavier is looking at the performance impacts of different compiler flags on Android builds Yanbin is following up with all the uses of SSL across Android to understand who is making use of the system SSL as compared to having their own copy. As the system SSL has been optimized we want to make sure that the other uses are improved as well. Yanbin has also been working on porting Bionic optimizations LCR for the month of January has been moved up to Android 5.0.2. We've had several issues with LAVA that have been blockers for us, this has included the inability to run CTS. We thank both Builds and Baselines through Vishal as well as the LAVA team for their assistance and direct involvement. GPGPU ====== Gil Pitney Show Liu The work to extend Shamrock to support OpenCL 1.2 has been looked at and documented in card-934. Gil has been leading up this work. Show has begun efforts to look into OpenMP and what state it is in across gcc 4.6, 4.9 and Clang. He is creating a wiki page of his experiences. OpenMP on Android has suffered from critical bugs that limit how it may be used. We are curious as to that status of those past bugs as well as where arm64 support is at with OpenMP in general in preparation to address member related OpenMP requests. LMG Kernel ========== Sumit Semwal Amit Pundir Grygorii Strashko The 3.14 LSK/Android kernel has been a focus item. We do see an uptick in Google activity in their own 3.14 kernel branch. A card for base hibernation support is being drafted. This is a piece of the effort to enable TuxOnIce functionality. Gregorii is focused on this 100% Amit has been working on Android gadgets upstreaming and helping out with the juno kernels and release oriented activities. Media & Gfx ========= Benjamin Gaignard Paramanand Singh Neil Wong Jia JIa (Missing, no status) Benjamin is looking into secure media using dma-buf. He is also looking into media framework efforts involving v4l and gstreamer for Android. This is preliminary work in the anticipation of what will be a proposed epic in the area. Benjamin has been working with ARM who have picked up the hwcomposer reference implementation for their own purposes. He has been including some patches and feedback from them. Neil has been working on libjpeg-turbo to integrate that into the Linaro Confectionery Release. As upstream efforts with libjpeg-turbo are paused he will be pitching in with the Android team. Paramandir has been putting together automated tests for the libvxp. -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"

Linaro android toolchain 4.9 2014.12 missing libatomic.a

by 박주형

AOSP 5.0 Lollipop requires libatomic.a for compilation; https://github.com/android/platform_build/commit/4c952d72b7aca4801e0ee4070c… And yet, Linaro android toolchain misses it. Can we expect the next release to include libatomic? Thanks in advance.

Jenkins and EC2 plugin upgrades

by Paul Sokolovsky

Hello, Per https://cards.linaro.org/browse/SYS-354 , Jenkins was upgraded to 1.580.2 and EC2 plugin to 1.24 (which is worth mentioning, as previously we held EC2 plugin version at 1.18). Upgrade was tested on android-build.linaro.org clone, then on android-build itself, and over the weekend, ci.linaro.org and tcwg-ci.linaro.org followed. The only regression with this upgrade is related to visual UI - in 1.580, Jenkins switched to a new theme, which is not compatible with existing Linaro theme, and Linaro theme actually causes some UI elements to be not available on new Jenkins version. So, it was disabled on all servers, we will look into updating Linaro theme at later time. Otherwise, I didn't see any build failure which can be attributed to the upgrade. In particular, EC2 slave provision works as expected and reliably with the new plugin. But please let me and Andy Doan know if you see any issue or have any question. Thanks, and Happy New Year! -- 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

Linaro Confectionary Release (LCR) 14.12 released

by Fathi Boudra

"Any technology that does not appear magical is insufficiently advanced." ~ Gregory Benford Linaro is pleased to announce the first Linaro Confectionery Release (LCR). LCR is a reference build of the Android-5.0.1_r1 branch for ARM’s Juno and Versatile Express TC2 hardware, and Fixed Virtual Platform (FVP) models. The goal of LCR is to provides a foundation for tested Linaro engineering efforts integrated with Android point releases. Only engineering efforts which have an established validation record are allowed to be added to LCR. LCR is conceptually similar to the Linaro Stable Kernel (LSK) project which uses Greg Kroah-Hartman’s Long Term Stable (LTS) source tree with Linaro members features added. LCR charts a comparable course that starts with Android point releases and includes Linaro member directed engineering to fix, optimize and enhance LCR. For 14.12, LCR uses the Android AOSP 4.9 GCC toolchain for building 64bit ARM binaries and the Android AOSP 4.8 GCC toolchain for building 32bit ARM binaries. LCR includes the 3.10 Android flavour of LSK for all 3 currently supported configurations. This means that the LSK includes Android kernel patches from the AOSP project. The Juno kernel includes ARM Mali drivers for accelerated 3D graphics support. LCR includes support for both single-arch 32bit ARMv7-A and multi-arch 32bit ARMv7-A, 64bit ARMv8-A Android systems. LCR is tested. CTS version 5.0, Android BIONIC tests, Android Monkey and other tests are used to validate the system. Testing performed should not be considered to exhaustive or necessarily product quality. Test results are available to Linaro member companies. The release can be found respectively at: * Juno: http://releases.linaro.org/14.12/android/lcr/juno * FVP: http://releases.linaro.org/14.12/android/lcr/fvp * Versatile Express TC2: http://releases.linaro.org/14.12/android/lcr/vexpress-tc2 If you should find a issue or have a question about the release, we invite you to use one of the following mechanisms: * IRC: irc.freenode.net - #linaro-android * email: linaro-android(a)lists.linaro.org * Bug Tracking System: Linaro Android project/Linaro Confectionary release component (https://bugs.linaro.org/enter_bug.cgi?product=Linaro%20Android) Support is on a “best effort” basis. -- Fathi Boudra, on behalf of the LMG/Android Team and Release Team Linaro.org | Open source software for ARM SoCs

[INQUIRY] Deleteing dalvik-vm-unit test

by Amit Khare

Hi, I am checking with linaro-validation and linaro-android mailing list to see if anyone is still using the outdated dalvik-vm-unit test. https://git.linaro.org/qa/test-definitions.git/blob/HEAD:/android/dalvik-vm… Since dalvik is not used any more and dalvik-vm-unit-tests is not in the aosp source any more, I'm planning to delete it from qa/testdefinition repo by the end of next week if there aren't any objections :) -- Regards, Amit Khare

Migrating android-build jobs to new publishing API

by Paul Sokolovsky

Hello, We've been readying new publishing API for some time now, and last week, I finished largest part of integration testing for android-build.linaro.org. The things looks good, and to remind, new publishing API will improve performance, security, and maintainability of the publishing. What's left on critical path to deployment are: 1. Resolving disk space problems on snapshots.linaro.org (which got on brink of overflow last week) - we'll be looking into this with ITS. 2. Preparing job migration scripts - in works by me. 3. Merging changes made in dew linaro-android-build-tools forks repos - Vishal works on this. So, with this mail, I'd like to call for final sync on these tasks, and schedule switchover for this week. Please let me know how that sounds and if there're any blockers to that.

clang builds are compiling for both ARMv7 and ARMv8 at last...

by Bernhard Rosenkränzer

Hi, we finally have post-L-merge AOSP master building with clang for both ARMv7 and ARMv8, and all related patches are submitted upstream. Now we just need to make sure we can fix things faster than upstream updates break them ;) I haven't had any success booting it yet (but the last images just finished compiling...), but I suspect some recent upstream changes (move to C++11 etc.) may have broken master for a bit and a gcc built version won't work either. That's the first thing I'll check tomorrow. ttyl bero

Panda 4430 vs 4460

by davidson

Hi, I'm using the 14.04 release of the Linaro Kitkat release for Pandaboard. In the 4430 Pandaboard the UI is smooth as expected. But in 4460, the UI response is slow and display remains still, frequently. Is there any patch to solve this problem? Any help is greatly appreciated. Thanks and Regards, Davidson. K
