Linaro Release 12.06 Postmortem Summary

by David Zinman

Postmortem and lessons learned for Linaro's release 2012.06 https://wiki.linaro.org/Cycles/1206/Release/Review Highlights and Key Successes ============================ Release 12.06 highlights the Android team's multimedia enablement being review on AOSP, and the update to Android version 4.0.4 r2. The video of Bero demonstrating the efficiency of the Linaro Android toolchain has now garnered over 230,000 views on Youtube. http://armdevices.net/2012/06/02/linaro-improvements-to-android-4-0-4-perfo… The Ubuntu team has created and published a new Linux Linaro branch, called Linux Linaro Tracking It contains the 3.4 Landing Team trees from TI, Samsung and ARM, delivering a single and unified tree which helps identifying conflicts and issues ahead of upstream. Postmortem and Lessons Learned ============================== Most of the topics for this cycle revolve around Linaro Connect. The success of the event is dampened by the shortened development cycle it creates. This time, Linaro Connect occurred over a release day. While this presented some challenges, some interesting positive issues were observed. Connect doesn't necessarily have to interrupt things. Possibly because of release week, planning for the cycle was accomplished while the teams were in the same location, which made issue resolution quicker and easier to discuss. Teams should follow this example to get code in early and use release week to plan for the next cycle. So it is up to each team to plan for pre and post Linaro Connect as well as planning for the cycle. The Infrastructure team has been experimenting with paired programming and a maintenance team. Each cycle 2 infrastructure engineers take the maintenance rotation to deal with high priority bugs and occurring issues. This is working very well and has helped facilitate speedy resolutions to some problems that came up during the cycle. Blueprints ========= The number of high or essential priority blueprints that missed the cycle: Android 5 out of 12 Developer Platform 3 out of 10 Infrastructure 4 out of 6 Lava 1 out of 3 Total 13 out of 31 42% of high or essential priority blueprints scheduled for this cycle were not delivered. Total blueprints: 31 out of 61 missed the cycle. High priority missed blueprints recap: 12.05: 19 out of 48, 39% 12.06: 13 out of 31, 42% * Not included is data from working groups and landing teams Source: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AjEaTwrvj1bidHZPL… -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs

Re: Problem building Precise Ubuntu Desktop

by David Cullen

Hello, Tom and Andy, A bizarre thing just happened. I used Ctrl-Alt-F1 to switch to the first VT. When I pressed Ctrl-Alt-F7 to switch back to X, the Unity GUI was displayed. However, when I opened Firefox and tried to navigate to YouTube, everything went black and I was left with only the mouse cursor. When I repeat the above steps, I get the same result. You can view the Xorg.0.log here: http://pastebin.com/3C1eXXPS The last line is very interesting: > [ 79.072] PVR:(Fatal): Debug assertion failed! [1785, /sgxtransfer_utils.c] It's the first thing I've seen that hints at the cause of my problems. -- Thank you, David Cullen

[PATCH v2] pm-qa: add powertop test cases

by Rajagopal Venkat

add powertop test cases into pm-qa. Run the powertop sanity test to check if tool is available. If yes, then run powertop in report generation mode and validate the output.

Finding required Kernel Source

by Sudhangathan B S

Hi, I need to re-compile 3.0.0-1002.3 lianro omap kernel to include MADC drivers. The reason is that the linaro-m 11.07 release uses this kernel, and I need to add this module to this release. Where can I find 3.0.0-1002.3 lianro omap kernel...??? I use overo-fire. Any suggestion on which release should I use to include the MADC drivers.... --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 ---------------------------------

Some question about the vmailloc size of Snowball

by Kejun Zhou

Hi All, Would you give me some help about Linux vmalloc size issue, if you have some idea about the vmalloc size? I saw the vmalloc size was changed from 256M to 300M: http://bazaar.launchpad.net/~linaro-image-tools/linaro-image-tools/trunk/re… Would you tell me how did you find out the vmalloc size issue? There is a bug https://bugs.launchpad.net/igloocommunity/+bug/1014650 And I found out a work around solution that is increasing the vmalloc size to 380M. Would you tell me how to make sure whether the root cause is the vmalloc size or not? Thank you.

Overo stability problem/Overo hwpack support

by Sudhangathan B S

To argue, I'm with Steffen Hemer, I'm working for a practical project, I'm trying to include MADC module and trying to compile a kernel for lot while now, without success, to be more serious, my boss is counting on me. Is it worthwhile trying this at all...? Every time i follow instructions at https://wiki.linaro.org/Resources/HowTo/KernelDeploy , I end up with a non-working image, or kernel that panics, doesn't boot finally. I have all the problems that Stefen Hemer says, though haven't tried 12.06. I have only tried upto 12.03 since 11.07 and also an old and stable 11.05 Ubuntu Desktop, which I downloaded long back. 11.05 is an image that i'm using since long for all activities now. I was pretty impressed with it, inspite of it being a little slow. Please advice which version should I use with LinaroMediaCreate and which version of kernel should I compile. I need these features: Stable Bluetooth, Wi-Fi with fully working Ad-Hoc mode, MADC, GPIO controls (which I never had problems), And also later dreaming to include advanced power management features and XIP kernel. I can share more detailed info if anybody out there says it's solvable.. Counting.... --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 ---------------------------------
