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.

[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

Quantal open for development

by Matthias Klose

Quantal is now open for development, with syncs from unstable starting shortly. The development version starts with updated versions of GCC and OpenJDK, some soname changes (boost, hdf5), and some changes with setting the build flags for package builds. We are finally targeting Python3 as the only Python version on the ISO/installation images. - GCC 4.7 is now the default, introducing some build failures caused by unknown compiler options, and more C++ strictness. Hints how to fix packages can be found at [1]. Bug reports for packages are not yet filed directly in Launchpad, but can be found on the Debian BTS instead [2]. - OpenJDK 7 is now used as the default, replacing OpenJDK 6, introducing some build failures. The build status can be tracked at [3], open issues are tracked at [4]. - Removing build flags exported from dpkg-buildpackage for quantal will get us in sync with Debian. Implications and fixes are discussed on the ubuntu-devel ML [5]. - Python 3 is now again part of a minimal chroot on quantal, and will be the only Python version provided on the ISO/installation images for quantal. Packages which need updates and ports for Python 3 are tracked at [6] Please check your uploads in a quantal chroot, don't just test in a precise environment. See [7] how to setup such a development chroot.

Re: linaro-announce post from tim@eclectronics.org requires approval

With the switch to Ubuntu Precise/armhf, several builds were broken or untested (LAVA was offline). That's the main reasons why BeagleBoard or Overo hasn't been published. Assuming we have a working, tested build and a sponsor, they'll be back. Cheers, -- Fathi Boudra Linaro Release Manager | Validation Project Manager Linaro.org | Open source software for ARM SoCs

won't someone please think of the users!?

by Clark, Rob

just some random thoughts on our release model, etc.. I've been meaning to write up for a while but haven't had time There has been some feedback, for example on #pandaboard, that the monthly release cycle is confusing and detrimental for folks looking for something working and stable, and not necessarily bleeding edge, the question is, "should I upgrade?", "what is fixed and what is now broken?". Linaro is doing some great upstream work, and enabling features on these boards, and it is good to showcase that, but I'm not really sure the best way to do this is rush that into the next monthly release and break things for all the new users of their shiny new xyz-board. I tend to think that part of the problem is that the cadence of monthly releases is too fast for any sort of stability. Perhaps we should think more along the lines of releases roughly every quarter (potentially with "beta"s in between). I don't think we should strictly adhere to a time based release cycle, but we should call it a final/stable release when it actually is so. There is a reason that the linux kernel uses an approx 3 month release cycle, but doesn't stick to that dogmatically when things aren't really at release quality yet. But, we do still need a place for latest-and-greatest bleeding edge for folks who want to check out what we are working on. One approach, for example for ubuntu releases, we could have a "release" and "trunk" PPA for bleeding-edge.. that way folks looking for bleeding-edge can get it, and folks looking for "it just works" are not screwed. I'm not quite sure what android equivalent would be, but I guess we could figure something out. This gives folks in board specific channels like #pandaboard who are trying to help new users something to reliably point them at without having to worry if they are giving bad advice to recommend a linaro filesystem. And updates do not have to be tied to a time-based schedule. If something is broken for feature x for board y in the release PPA, then as soon as it is fixed (and if it doesn't break board z), then push an update to the release PPA. But maybe big new features shouldn't immediately go to the release PPA without some soak time first in the trunk PPA. It is great to be enabling new features, but for someone new to the arm platform I don't want to just frustrate and scare them off. Also, I wonder if we should split #linaro, either into #linaro-devel and leave #linaro as a place that users can come to for help, or setup a separate #linaro-users? This way we aren't just dumping out new releases with nowhere for users to turn to for help.. (Well, they can always come to #linaro but I guess this would help with the signal-to-noise..) BR, -R

[PATCH 00/13] common clk framework misc fixes

by Mike Turquette

This series collects many of the fixes posted for the recently merged common clock framework as well as some general clean-up. Most of the code classifies as a clean-up moreso than a bug fix; hopefully this is not a problem since the common clk framework is new code pulled for 3.4. Patches are based on v3.4-rc2 and can be pulled from: git://git.linaro.org/people/mturquette/linux.git v3.4-rc2-clk-fixes Please let me know I missed any critical fixes that were posted to the list already. Arnd & Olof, if there are no objections to these changes can this get pulled through the arm-soc tree?

Linaro U-Boot 12.04 released

by John Rigby

Version 12.04 of Linaro U-Boot has been released. Details on Launchpad here: https://launchpad.net/u-boot-linaro/trunk/12.04 And on git.linaro.org here: http://git.linaro.org/gitweb?p=boot/u-boot-linaro-stable.git;a=shortlog;h=r… >From the release notes: This release is primarily a rebase onto the latest upstream git.denx.de release v2012.04. Several patches that have been carried in u-boot-linaro have been dropped because that functionality has gone upstream. This includes OMAP[345] usb support including network support on Panda and Beagle xM and the Highbank support from Calxeda. This release continues to include some Snowball support but not enough to be usable. This release also still requires the cache disabling patch for OMAP3 that has been carried for months but upstream remains broken with Linaro kernels without it. See Changelog for list of all patches to v2012.04.

Screen sizes for a tablet device - Not related application development.

by Venkat Raghavulu

Hello All, I need some help, checked the android documentation and related area, did not get a solution. This is on screen size for tablet devices during the boot stage. Problem statement: The device is a 7" LCD device (H=480, W=800 device), when Android boots "SYSTEM UI is not loaded" message pops up and the navigation/notification bar does NOT appear/display. However all operations like screen navigation etc are all working and we are able to navigate through a mouse!!! I am using a customised version which is a slight offset of SNOWBALL LINARO ICS.

Per build EULA handling

by Georgy Redkozubov

Greetings, We have depoyed per build EULA handling on http://snapshots.linaro.org as a part of downloads click through license protection. Now only "origen" and "snowball" builds that has binary blobs inside are protected by EULA and at the same time all other builds are open source and don't require license acceptance. To protect files in specific directory, the EULA.txt should be placed in that directory. Otherwise OPEN-EULA.txt should be there. These files triggers displaying license page based on build name and after accepting license downloading begins. If there are none of them the user get "Forbidden" page. Appropriate EULA is added automatically by the build system. -- WBR, Georgy Redkozubov 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
