CO * Achievements / progress reports * OMAP3 . See activity report * Versatile Express * Low hanging fruit: validating audio on Vexpress; seems to be broken, but Matt was told it's expected to work and is trying more stuff out (as suggested by Pavo) * Getting defconfig added to the upstream kernel * Worked with plars on getting https://launchpad.net/abrek working; many low-level failures with LTP; not sure which ones are serious or not * MMC support in u-boot would be helpful for some use cases; impacts flash-kernel * flash-kernel: might make sense to send udeb changes as well, not only runtime changes; need to make sure they land in Ubuntu * Very slow boot; need to log a bug for that * Could be initrd or rootfs * Seems there's an extra copy of the initrd going on at boot; need to research this a bit more; might be the boot commands; notably for LP #629614 * Loic would love some data on the kernel configs which are needed for Vexpress boards * Matt needs to investigate the MMC/USB conflict a bit more * Mounir would like to help more, but isn't sure where he can contribute * Loic suggests that consolidating information on board status, and describing hw enablement processes would help as they are currently lousely coupled Activity reports for last week = Matt Waddel = == this week == * Fixed deploy mechanism for ARM compatiblity * Refactored u-boot patches to apply to the next branch * pushed to u-boot * Fixed bug 637780 - 2nd flash bank problem * Bug fixing on vexpress - memory issue, initrd on command line * frame buffer corruption - LP: #633417 * Will Deacon sent a much better cache setup patch - pushed to linaro kernel * abrek (QA system) - investigation and setup * flash-kernel implementation - submitted patch to debian maintainers * Tried Lorenzo's vexpress arm device-tree kernel * Device tree defaults don't work with my monitor, but kernel boots * Upgraded Vexpress to Maverick == next week == * Validate new images and close bugs * Fix linaro-media-create bugs assigned to me * Submit flash-kernel review suggestions * Vexpress enablement test documentation and development * Start mmc u-boot support = Torez Smith = 1) Monday morning went to install and boot daily build and found it did not build over the weekend nor up to today.....added tools/perf package caused it not to build...opened a bug for this (bug 643462 Linaro build process fails to generate builds for 20100919 and 20100920 ) . I'm looking for the daily builds to assure no regression and to pick up the changes I made for the IGEPv2 networking (bug 618734 [omap/igep] No eth0 with Linaro kernel). >From the looks of the bug, these changes should be included in the next daily build 2) finishing up bug 619206 ( GEP task - libertas-firmware not installed<https://bugs.launchpad.net/linaro-seeds/+bug/619206>) and looking at bug 622429 ( ethernet device appears as usb0 and not eth0 on beagle XM boards<https://bugs.launchpad.net/linux-linaro/+bug/622429>). 3) my bug 633338 (no LCD support on IGEPv2 board) was found to be a duplicate of bug 607250 (omapdss: VDDA_DAC regulator on IGEPv2) which has a corresponding patch they are pulling in. 4) next step is to look at the powervr driver changes in the "ARM Graphics Stack on X" Blueprint. -- Loïc Minier

Toolchain WG helper programs

by Michael Hope

We've got a few little helper programs that are used in the Toolchain WG to help things run smoothly. I've done a short write up on them here: https://wiki.linaro.org/WorkingGroups/ToolChain/Helpers Ulrich, this is the build system I mentioned on the call. Scott/James/Mounir, it's not great, but this gives you an idea of the tools I'd like to hand over. -- Michael

OpenOCD

by Zach Welch

Hi all, I was recently hired by CodeSourcery and have been assigned to Linaro for the purpose of improving OpenOCD. Specifically, I will be adding new support for Cortex-A9 SMP, though I may also make a few improvements to its handling of Cortex-A8 in the process. If you have experience using OpenOCD in these contexts, let me know if you have any specific requests for features or fixes, and I will try to fold them into my plans. After this cross-posted introduction, I believe that most of my correspondence will appear on the Toolchain mailing list, but I wanted to make sure that everyone knows that they can find me there. Cheers, -- Zach Welch CodeSourcery zwelch(a)codesourcery.com (650) 331-3385 x743

Current state of PM tools

by Amit Arora

This mail is to give an update on the current state of PowerTOP and PowerDebug tools. The patch to make PowerTOP work on ARM boards too (by removing the hardcoded values for these states) has been included in upstream. This patch has also made it into the Maverick PowerTOP package (https://launchpad.net/ubuntu/maverick/+source/powertop/1.13-1ubuntu1). Request you to test this package on whatever hardware you may have (x86/arm) and report any problems that you may encounter. PowerDebug is a new tool that we are working on which will provide some more Power Management related information, like - Regulator, Sensor and clock domain information. The source code can be downloaded from my git tree (git://git.linaro.org/people/amitarora/powerdebug.git) OR from my PPA (ppa:amitarora/pm-utils). Its still at experimental stage and is under active development. Feel free to try it out and give your valuable feedback. Thanks! Regards, Amit Arora

Fwd: Linaro Infrastructure Team Weekly Report (2010-09-09 to 2010-09-16)

by Ian Smith

Correct report link updated! -------- Original Message -------- Subject: Linaro Infrastructure Team Weekly Report (2010-09-09 to 2010-09-16) Date: Thu, 16 Sep 2010 10:32:12 +0100 From: Ian Smith <ian.smith(a)linaro.org> To: linaro-dev(a)lists.linaro.org The weekly report for the Linaro Infrastructure team may be found at: Status report:https://wiki.linaro.org/Platform/Infrastructure/Status/2010-09-16 Burndown chart:http://people.canonical.com/~pitti/workitems/maverick/linaro-infrastr… The burndown chart is showing that number of work items has increased, with a number of work items completed. This is showing that the number of work items to complete is slipping further behind the trend line. * Merged XML-RPC API and client and various fixes to them * Got initial set of views into trunk. Currently this adds support for browsing streams. While simple, it paves the way for more views (the task is simple and repetitive) as we support authentication, unit tests and other goodness that made it take longer. * Got generic databrowser merged. This allows anyone to browse everything that is in the database (so any bundles/tests that are already in can be accessed without extra effort). This will act as a temporary view layer before we can iron out what people actually want from us. * "Decide on dependency management approach (debs/buildout/...)": DONE * "Implement dependency management": DONE. * HardwarePacks: hwpack-install: landed and fixed a couple things reported by asac Please let me know if you have any questions. Kind Regards, Ian

New projects and copyright

by Michael Hope

I don't understand the page at: https://wiki.linaro.org/Copyright I've put the new Toolchain WG web tools up on Launchpad so that others in the group can get it. It needs a README (fine), license (EPL apparently), and copyright statement. I'm paid by Canonical but work for Linaro. The Copyright page says that new work is (C) Canonical and then the copyright 'flows' to Linaro. What does this mean and how do I achieve it? What copyright statement should be on the work and where? At a different level, how do you apply the EPL to a project? What text should I have in what files to record the license and copyright? Is there a standard way of doing this? -- Michael
