For those who haven't registered the Android Builder Summit & Embedded Linux Conference.

by Botao Sun

Hi, I find there is a tricky discount which is hidden between the ABS and ELC events. If you want to get that discount, register the ELC first. During the ELC registration pages, it will tell you if you also want to attend the ABS, the ticket price will be USD 150. The original ABS ticket price is USD 325. But there is no any discount information if you register ABS first. So if you register the ABS first (like me, unfortunately), you will pay the full ticket price on both events. I have sent an email to them to ask the refund but I'm not sure they will accept. I haven't received their feedback yet. FYI. BR Botao Sun

Streamline benchmark delivery to toolchain

by Zach Pfeffer

We've started to spin up an effort to automate Android benchmarks in LAVA (thanks Andy and Bero). The toolchain group is interested in these results and would like the results in raw text form so that they can extend their parser to read it. I figured we should just shoot for this first since getting benchmark results to the toolchain group is very important. Does this sound good to you Andy and Bero? Michael/Åsa would you guys mind sending a sample of a preferred format and how you'd like it delivered? Paul, what ways can LAVA push out a text file? -- 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

Re: Good news for USB on Snowball

by Mathieu Poirier

Friends, Jesse found this connector: http://parts.digikey.com/1/parts/1637446-cbl-usb-a-rcpt-mini-a-plug-102mm-1… It *should* work and for our friends in India I just found this: http://www.digikey.in/ Happy shopping, Mathieu. PS: If someone ends up buying the connector please get back to us with your results. On 12-01-10 03:50 PM, Mathieu Poirier wrote: > > Jesse, > > That is an interesting setup you have there.

Good news for USB on Snowball

by Mathieu Poirier

Good day all, It is now possible to get input from multiple USB device using a powered USB hub. In my current setup I have a mouse and a keyboard and everything works well. Only basic functionality is supported - USB hot plug and return from hibernation will not work. This has been tested on landing-snowball builds for kernel 3.0 and 3.1, the latest can be found here: https://android-build.linaro.org/builds/~linaro-android/staging-snowball/#b… The feature has been proven to work with V5 and V11 boards. Special thanks to our 3-stars kernel engineer Philippe Langlais and the STE connectivity team for their relentlessness work on this problem. Best regards, Mathieu.

Notes from Platform - Working Group Sync January 10, 2012

by David Zinman

Power Management Item: ===================== One of the roadmap cards the PMWG is working on is the thermal management card. http://status.linaro.org/card/PMWG2011-THERMAL-MANAGEMENT.html One of the acceptance criteria for this item is: Thermal management should be validated on an Android image; a suggestion is to run the system on the highest OPP, and use that to trigger the thermal transition. Per Amit D., This topic has been discussed with Samsung landing team, they will pick these patches for hwpack and android release. I want to make sure this happens and the patches make it to an Android image that we can test with on Samsung platform. Android Agenda Items =================== 1. Single kernel? 2. Benchmarks-to-toolchain-group work 3. Developer tools 4. MM help with Video Conferencing 5. GFX help GLMark2 6. PM on all Android targets 7. How else can Android help you? Notes: --------- * Single Kernel status unknown. * Valgrind +2 * MM help with video conferencing? * How can Android better help you * MM? Panda Audio enablement, Vishal question, what’s the plan for the rest, AI for Zach to send plan. * GFX? Wiki pages are helpful. Some kind of dev guide. PoC list for Android issues. * Toolchain: Valgrind, auto-benchmarks, PoC lists, getting going * PM: Power Tutor, stalled out, Zach to pick back up , Amit can you, once CPU idle, pick i up support * KWG: ??? Dev Platform Agenda Items: ======================= 1. Deliverables that might affect Ubuntu 2. How to make sure PM is properly integrated at the Ubuntu targets 3. MM and work needed to improve XBMC and Ubuntu TV (qtmobility) 4. GFX planning for 12.01 and work with Unity 3D 5. Anything missing at the Dev Platform (images, tools) that might be interesting for other WGs? Notes: --------- * Michael is fine with the current sysroot produced by Marcin, and plan to keep validating it by hand once they are available. Maybe a discussion should happen at Connect to see if this can be automate. * Please send Ubuntu input to Ricardo. * Still not sure if Ubuntu is properly using power management (as the LT is maintaining the tree and config set), Amit will take a look and see if anything is missing. * Point to MM working group, XBMC and Ubuntu TV, can the MM WG help? Ravi is. Kan Hu - XBMC still need a person for Ubuntu TV. * Mark and Alexandros is working on Unity-3D upstreaming. Fighting against time. They are the correct PoC for Unity-3D upstreaming for this month and through Connect. * Ricardo, are there any other tools that people need in Ubuntu? Jesse, images are fairly good. Validation Agenda Items: ==================== 1. There was some recent discussion with mmwg about audio e2e testing, and whether we should be testing this over hdmi for boards that default to hdmi, or whether all boards should start with a test to simply cover the jack loopback. 2. Kernel WG testsuite progress? Notes: --------- * End-to-end audio test. Need to handle HDMI audio test. Audio loop-back over jack is one test case and HDMI audio loop-back is a seperate test. Need HDMI test in the next 3-4 months. * Need to get audio test into LAVA. * Tom to work on Android and other higher level tests Housekeeping: =========== The quality of voice really sucks. Any suggestions for a public platform, or should we move back to #linaro-meeting? - Mumble seems to work better, as you can see where the noise is coming and mute the person (but people generally have issues with mumble). - Google Hangout? Would probably work fine too (it’s the only good thing of google+ ;-) There are quite a few conflicts with this time slot, we need to reschedule. I (dzin) will try to find a more appropriate time slot. Apologies and please bear with me. ============== = Action Items: = ============== Amit will send out CONFIG options to check and a test we can run by hand for http://status.linaro.org/card/PMWG2011-THERMAL-MANAGEMENT.html. Ideally this would be part of the pm test case available at LAVA. Besides config enablement, would be good to check with LTs if they are including the needed patches and so on. Zach to spin up a thread about feeding raw data to the toolchain grouphttp://status.linaro.org/card/PMWG2011-THERMAL-MANAGEMENT.html Zach to send an email to KWG. Ricardo to spin up a BP for remaining XBMC and Ubuntu TV work (2 different BPs to target 2 people) Zach to meet with Benjamin. Tony to talk to Alexandros about GLMark2 integration work, Zach to get a thread going. David to send out a summary to linaro-dev and linaro-android. -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs

Fw: linaro-android_staging-imx53 started to fail due to big build/out/ size

by Paul Sokolovsky

Sorry, didn't get to the mailing list on first , reposting so all folks had a chance to see it.

Ok, that was fixed on Friday (by having only build/out/target/ on the ramdisk). Alexander also asked to provide means manage risk of that reoccurring again during hot time. You can add "RAMDISK_SIZE=0" in such case. I don't expect that happening anytime soon (have ~3Gb free now), so just FYI.

Sync and Build Failure in 11.10

by Bharathi Subramanian

Hi All, New to Linaro. We are trying to sync the source for Panda Board, as per the steps mentioned in the following link: https://wiki.linaro.org/Platform/Android/GetSource We are unable to sync the two projects from external folder. So skipped thous projects. We used both default (GCC 4.4.0) and Linaro (GCC 4.6.0) toolchain. But build is unsuccessful. When we did a web search for the error, it was mention that as compiler issues. Can someone share, which is the suitable Android release for development? Bye :) -- Bharathi Subramanian
