Greetings, I've just created linux-linaro-core-tracking branch in git://git.linaro.org/kernel/linux-linaro-tracking.git. It is based on mainline tip, and has all the Platform and Working Groups topics which would appear in the next linux-linaro kernel release. No topics from the Landing Teams there (this is what "core" implies). This tree will be the basis for the next (12.05) linux-linaro kernel release. So if you have a topic to be added to 12.05 you can ask me to add it (the sooner you ask, the better), and it will appear in linux-linaro-core-tracking first. The request to add a topic must include the git tree location for me to pull the topic from, and the base used by this topic (mainline, or another topic). If no base for the topic is specified, the mainline is assumed. If needed, this is ok to rebase the topic; this would be easier for me to handle than e.g. reconfiguring my scripts to use topic-3.4rc5 branch instead of topic-3.4rc4 branch used so far etc. Again, starting from now this tree is open for the next release (12.05) topics. The linux-linaro-core-tracking tree is first of all to identify the conflicts early, so it could fail to build sometimes, or the kernel built from it may not boot etc. The plan is to rebase this tree on the current mainline tip daily. The topics causing the conflicts would be excluded from the linux-linaro-core-tracking tree, and would be brought back into it after the conflicts are resolved by the topic owners. Thanks, Andrey

PowerVR, 3.3 kernel and omap_drm

by Martin Ertsås

Hi. I have gotten a lot of help from you guys getting the PowerVR drivers up and running with the 3.3 kernel on the Pandaboard ES. Problem now is that all I tested then, was that X was running. After some more work, we tried out EGL, and found out that this is not working. The 3.3 kernel I'm using is revision f8e851d03e884b60b5207f59a342da9cafdb415f from tilt-3.3 from the ti-landing team. I'm using the PowerVR drivers in http://ppa.launchpad.net/tiomap-dev/omap-trunk/ubuntu/pool/main/, that is pvr-omap4_1.7.15.0.1.57 and pvr-omap4-dkms_1.7.15.0.1.54. I'm also using the libdrm, libdri2 and xorg server from the same place, using the versions from: https://launchpad.net/~tiomap-dev/+archive/omap-trunk?field.series_filter=p… Problem is, when trying to run something using EGL, I get the output from: http://pastebin.com/e5deVmiD Running it through gdb on the device, I see that it segfaults in omap_bo_handle in /usr/lib/libdrm_omap.so.1 This file is compiled, using the patches listed in debian/patches/series in the latest commit from git://gitorious.org/ubuntu-omap/libdrm.git, and with configure arguments: --enable-omap-experimental-api --enable-udev --enable-libkms --disable-radeon Any ideas on what might be wrong or what I can try? I have tried copying the libdrm_omap binary from the ppa, as it looks like that might be at fault, but no luck. Best Regards Martin Ertsas

No group tracks at Connect

by Zach Pfeffer

While we're planning for connect, I'd like to suggest that we do away with team tracks all together and just have topic tracks. This would align with our topic based approach to things now, and would be a way to breakdown our silo's. The topic track would be lead by a topic champion. What do people think? -- 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

Blueprints and topics to be covered at 12.05 by the Developer Platform Team

by Ricardo Salveti

Hi, Trying to get back to the proper way of scheduling and publishing what will be covered by the Developer Platform team during the 12.05 cycle, follows the blueprint description of what we're planning to work on during this cycle. Milestone link: https://launchpad.net/linaro-dev-platform/+milestone/12.05 The list is quite long, but most of the blueprints are basically covering work that was supposed to get done during 12.04, that unfortunately got blocked once LAVA got off-line. Some interesting topics we'll cover this month: * Common Ubuntu kernel config fragment across all kernel packages used at the LEB * Ubuntu sauce produced as a topic branch for Linux Linaro * Cross toolchain updates based on 4.7 for Quantal * Enablement test cases to be used with LAVA (usb-host-mode and others) * Cross buildd and multi-arch fixes planning work that might come with the ARMv8 effort Hopefully this cycle we'll also be able to get the images in a better shape sooner, trying to get the QA and Release team more involved with our releases (to improve our image/builds quality). Thanks! -- Ricardo Salveti de Araujo

[PATCH 00/18][V3] ARM: OMAP3/4 : cpuidle34xx and cpuidle44xx cleanups

by Daniel Lezcano

This patchset makes some cleanup on these cpuidle drivers and consolidate the code across both architecture. Tested on OMAP3 (igepV2). Partially tested on OMAP4 (pandaboard), without offlining the cpu1. V3 : * replace OMAP4_NUM_STATES and OMAP3_NUM_STATES by ARRAY_SIZE * Fixed changelog * Fixed OMAP4_NUM_STATES going back and forth in the patchset * Removed erratum check at init time V2 : * Fixed a couple of typos in the patch description V1 : Initial Post Daniel Lezcano (18): ARM: OMAP4: cpuidle - Remove unused valid field ARM: OMAP4: cpuidle - Declare the states with the driver declaration ARM: OMAP4: cpuidle - Remove the cpuidle_params_table table ARM: OMAP4: cpuidle - fix static omap4_idle_data declaration ARM: OMAP4: cpuidle - Initialize omap4_idle_data at compile time ARM: OMAP4: cpuidle - use the omap4_idle_data variable directly ARM: OMAP4: cpuidle - remove omap4_idle_data initialization at boot time ARM: OMAP3: cpuidle - remove rx51 cpuidle parameters table ARM: OMAP3: define cpuidle statically ARM: OMAP3: cpuidle - remove errata check in the init function ARM: OMAP3: cpuidle - remove the 'valid' field ARM: OMAP3: cpuidle - remove cpuidle_params_table ARM: OMAP3: define statically the omap3_idle_data ARM: OMAP3: cpuidle - use omap3_idle_data directly ARM: OMAP3: cpuidle - simplify next_valid_state ARM: OMAP3: set omap3_idle_data as static ARM: OMAP3/4: consolidate cpuidle Makefile ARM: OMAP3: cpuidle - set global variables static arch/arm/mach-omap2/Makefile | 11 +- arch/arm/mach-omap2/board-rx51.c | 38 +++--- arch/arm/mach-omap2/cpuidle34xx.c | 306 +++++++++++++++---------------------- arch/arm/mach-omap2/cpuidle44xx.c | 134 +++++++---------- arch/arm/mach-omap2/pm.h | 38 ++--- 5 files changed, 212 insertions(+), 315 deletions(-) -- 1.7.5.4

pull build configs into Git.

by Zach Pfeffer

Fathi, Since we're at the start of 12.05 we need to shift the builds over to the tip toolchain and stop daily builds for various baselines. I figure we can also get the configs into git. Do you want to take care of getting the current configs into git and then shift the builds or the other way around? For 12.05 I'd kill all dailies except for the tips listed on android-build.linaro.org under: "Users who are interested in tip builds with Linaro goodness should use:" People can always re-enable dalies they're interested in. -- 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

Linaro Release 12.04 Postmortem Summary

by David Zinman

Postmortem and lessons learned for Linaro's release 2012.04 https://wiki.linaro.org/Cycles/1204/Release/Review Highlights and Key Successes ============================ The Linaro 12.04 delivery included ARM Fast Models a platform which assists programmers by giving them a virtual environment to develop software for unreleased silicon. The migration to Ubuntu 12.04 (Precise Pangolin) by the Ubuntu Developer Platform team was delivered and built for armhf. Linaro U-boot is now based on the upstream release v2012.04.1. Support for big.LITTLE integrated switcher continues to be added to deliverables. The Snowball board has been enabled with multimedia support by the Android team. The team is also supporting big.LITTLE testing and development. Postmortem and Lessons Learned ============================== The unavailability of the LAVA lab was a perpetual handicap throughout the cycle. Consequences of the inaccessible lab include inconsistent testing of the images, possible missed issues, and the reduced quantity and quality of deliverables. Jenkins scripting has also been unstable for this cycle adding to the unpredictability of the release. However, even with these problems, the engineers pulled together and exhibited some great teamwork and effort in order to release on time. Particular acknowledgement goes to Fathi, Paul L., Abhishek, Botao, Ricardo, Andy D., Deepti, and Georgy. Some of the teams are dealing with staffing issues with the departures of a few members, and new people coming on board. Some teams have reduced resources. An issue that some teams have drawn attention to is the opaqueness of the TSC and roadmap process. Some roadmap processes are requested of teams with little notice for delivery, and without good communication of the deliverable. Some lessons learned from the cycle are: * Need a staging area with the same setup as production * This would mitigate the risk of an essential build service like LAVA and Jenkins going down * Can be deployed to production, staging and personal environments. * Validation server has a ton of data that is not duplicated in personal environments. It is important to be able to work from a backup copy * Blueprints should be updated on a weekly basis and given particular attention at the beginning of the cycle. * When IS issues happen, use the IS stakeholders: Joey, Danilo, Fathi. Platform Blueprints ---------------------------- The number of blueprints that missed the cycle: Android 22 out of 35 Developer Platform 12 out of 22 Infrastructure 5 out of 10 Lava 7 out of 11 Total: 46 out of 78 59% if blueprints scheduled for this cycle were not delivered. * Not included is data from working groups and landing teams Source: https://docs.google.com/a/linaro.org/spreadsheet/ccc?key=0AjEaTwrvj1bidDFtQ… -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs
