Greetings, Here is the post-mortem and lessons learned review for Linaro release 11.10. Thanks to the teams who have contributed to this. ==================== Release Review 11.10 ==================== Android ======= Highlights * Gerrit CI was well tested when deployed. * Making test results visible created quality awareness across the organization. Issues * Infrastructure capacity (git server) was inadequate and affected developer performance. * The one-month cycle leaves no room for events like Connect and ELC-E. * Heavy reliance on landing teams as most issues are theirs. * Bugs fixed in Developer are marked fixed even if not working on Android. * Landing teams seem to get too little support from member company developers. * The manual test frenzy at release time should be reduced or better shared. * Engineers that also have interrupt type duties struggle with Milestone delivery accuracy. * Daily test errors did not get immediate attention. Developer Platform ================== Highlights * Successful release on Oneiric ahead of schedule * CI on packaged kernels working * Communications need to be examined * John released U-Boot in time! That's great and keep up :) * Release process went fairly well Issues * Blueprints were not updated very well. * Launchpad issues blocked many blueprints * builders in LP were blocking some blueprints * Offspring and LP related issues take time to resolve * Lauchpad: to many bugs on derived distro support * testing was not done well on the LP side * Issues with the WGs: some did not release on time * communications were not smooth or even non-existent * transparency of plans is the problem; platform teams need to be aligned about plans * Unity tree not available on time, released only on Friday * Once tested, it did not work on Panda - it seems that Unity is not tested on Panda * The working group should continuously push to public * lack of communication and support for hardware problems * LAVA interface very slow - needs rework * requires better error reporting of the LAVA web service (error on job submission with wrong hardware pack) * Need better navigation of job from build to result in the dashboard UI * Linux-linaro quality isn't really good (no strict tracking of features etc.) * device tree is missing regularly. * Test cases should be provided well in advance of testing * Test cases in spreadsheet are vague, some not valid to test Lessons Learned * set up a point of contact with working groups for any issues during the release. * establish a best-practice process for the graphics group to continuously push to public * tests could have been better defined; next step is developing it. Kernel ====== Highlights * Pinctrl core and pinmux are now in linux-next. currently, answering late review comments and merging smaller patches. * Continued to implement Device Tree support for Linaro member platforms, focusing on changes to drivers and subsystems inlcuding IRQ controllers, GPIO, serial devices, MMC devices, and regulators across various SOCs. All i.MX basic drivers are ready, audio and usb are still big missing pieces. * omap-hsmmc dt conversion completed. Prepared single device tree enabled board file for smdkv310 and Origen boards and tested device tree support for the following modules: UART, SDHCI, Keypad, GPIO keys, DMA, RTC, I2C, WDT, GPIO, IRQ. * Continued with SoC Tree maintenance, code review, merging and verifying patches. * Continued work on fixes and changes to the config fragment merge_config.sh script, resubmitted merge_config.sh script to lkml. * Continued the cleanup and consolidation of various kernel headers that will allow for building of a single kernel across multiple SOCs the work included: patches to rework the low level UART debugging code on OMAP1, OMAP2 and Davinci, patches for mach/memory.h removal, patches for appending of a device tree binary to the kernel zImage and patches for removing all instances of mach/vmalloc.h. Multimedia ========== Highlights * There was a speedy reaction to get headlines andacceptance defined faster. Teams had those in place (90% of the BPs) by the deadline. * Managed to move ahead with some of the issues we have been facing eg Unity upstreaming in GFX. Issues * Quite a few blueprints did not complete. This can be attributed to a few possible reasons: * work was larger than initially thought * assignee was distracted to other activities * trees needed to be more carefully constructed at times to avoid mistakes from being based on old versions of upstream * assignee not "gardening" blueprints diligently * Sometimes the work is done but the blueprint doesn't reflect the reality General lessons learned * Maintain a tree always available. If tree is broken we should have a good idea when it will be available again. * Always work on the tip and fix things as they appear - that is easier said than done for some projects. So we check the cases one by one on the projects involved * Raise the risk flag early: kudos to those of you who did so this month. Perhaps an improvement next would be to try and anticipate the risk with each work item rather than on the blueprint level. * Even if you think that the release is not worth the effort, for example an optimization in performance did not show up, it is always good to make the release if you have patches which do not break the component. You will get more eyeballs looking at the components this way maybe that will help unearth other issues or suggest new ideas. Power Management ================ Highlights * Thermal management is working on Samsumg platform. However, the code is not pushed to mainline yet. * OMAP Thermal management integrated and delivered to TI. But, still under testing and not completely working. * PM QA testsuite now includes tests for hotplug integrated with LAVA, studying LAVA test runs for accuracy. Issues Toolchain ========= Highlights * Released Linaro GDB 7.3 11.10 * Released Linaro GCC 4.6 2011.10 and Linaro GCC 4.5 2011.10 * Released Linaro QEMU 2011.10 Issues Validation ========== Highlights * Initial release of bundle format documentation * Ability to display reports on the front page. Issues * Oneiric complicated packaging, weakened testing and development focus. Infrastructure ============== Highlights * Released linaro-image-tools 2011.10 * Didn't have to keep up with board changes due to hwpacks v2, already a success for that project. Issues * Had to change to cope with a breaking change in the format of rootfs created by live-build. We should add metadata to the rootfs to avoid this problem in future. Session registered at Connect to discuss it. https://blueprints.launchpad.net/linaro-ubuntu/+spec/linaro-platforms-p-ima… Lessons Learned Headlines * Headlines assumptions did not come true * To be ahead of the curb, in the PMWG, we created the monthly headline one week ahead of time * Not all headlines completed * wait until after the release to do the headline Quality * Quality status not known at all times * Important to ensure quality awareness across the organization * Less quality focus * Document what we test and then keep testing it Blueprints * Blueprints do not reflect reality * Invalid functionality * Work in small chunks on the days up to the release. Plan to release early and often as work items are done. Do not wait to have some mad dash in the hours before the release -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs

Need testing on other machines

by David Gilbert

Hi, The attached test intermittently fails on my panda running the 11.09 (3.0.0-1404-linaro-lt-omap) kernel; but it works on guinep and Michael's ursa and pavo running much older kernels; I'd appreciate it if people could try it on whatever machine with whatever kernel they have and report the result to me so I can try and nail down what it fails on. (It fails in both natty and oneiric chroots for me) To compile: gcc pthreadtest.c -o pthreadtest -lpthread To run: for SEQ in `seq 1 1000` do ./pthreadtest done if it finishes then its fine, for me it'll fail sooner or later with: Start thread test 0x110dc 0x110dc and just stop. (It sits there in a futex inside pthread_cond_wait on cond_wait's internal structure) Dave

[RFC PATCH 0/4] ARM: Exynos4: Thermal solution using Linux thermal infrstructure

by Amit Daniel Kachhap

This RFC version of the patch set is intended to share the current work about providing a thermal solution using Linux thermal infrastructure. The closest driver which has the same features and not using acpi layer is drivers/platform/x86/acerhdf.c. For the ARM world there is no clarity for placing such files so currently I have placed the temperature sensor driver and a binding layer for cooling device, thermal zone and core thermal interfaces inside staging directory. Feel free to comment about the implementation, the directory structure and the shortcomings. Amit Daniel Kachhap (4): ARM: Exynos4: Add thermal sensor driver for samsung exynos4 platform.

Proposal for a low-level Linux display framework

by Tomi Valkeinen

Hi, I am the author of OMAP display driver, and while developing it I've often felt that there's something missing in Linux's display area. I've been planning to write a post about this for a few years already, but I never got to it. So here goes at last! --- First I want to (try to) describe shortly what we have on OMAP, to give a bit of a background for my point of view, and to have an example HW. The display subsystem (DSS) hardware on OMAP handles only showing pixels on a display, so it doesn't contain anything that produces pixels like 3D stuff or accelerated copying. All it does is fetch pixels from SDRAM, possibly do some modifications for them (color format conversions etc), and output them to a display. The hardware has multiple overlays, which are like hardware windows. They fetch pixels from SDRAM, and output them in a certain area on the display (possibly with scaling). Multiple overlays can be composited into one output. So we may have something like this, when all overlays read pixels from separate areas in the memory, and all overlays are on LCD display: .-----. .------. .------. | mem |-------->| ovl0 |-----.---->| LCD | '-----' '------' | '------' .-----. .------. | | mem |-------->| ovl1 |-----| '-----' '------' | .-----. .------. | .------. | mem |-------->| ovl2 |-----' | TV | '-----' '------' '------' The LCD display can be rather simple one, like a standard monitor or a simple panel directly connected to parallel RGB output, or a more complex one. A complex panel needs something else than just turn-it-on-and-go. This may involve sending and receiving messages between OMAP and the panel, but more generally, there's need to have custom code that handles the particular panel. And the complex panel is not necessarily a panel at all, it may be a buffer chip between OMAP and the actual panel. The software side can be divided into three parts: the lower level omapdss driver, the lower level panel drivers, and higher level drivers like omapfb, v4l2 and omapdrm. The omapdss driver handles the OMAP DSS hardware, and offers a kernel internal API which the higher level drivers use. The omapdss does not know anything about fb or drm, it just offers core display services. The panel drivers handle particular panels/chips. The panel driver may be very simple in case of a conventional display, basically doing pretty much nothing, or bigger piece of code, handling communication with the panel. The higher level drivers handle buffers and tell omapdss things like where to find the pixels, what size the overlays should be, and use the omapdss API to turn displays on/off, etc. --- There are two things that I'm proposing to improve the Linux display support: First, there should be a bunch of common video structs and helpers that are independent of any higher level framework. Things like video timings, mode databases, and EDID seem to be implemented multiple times in the kernel. But there shouldn't be anything in those things that depend on any particular display framework, so they could be implemented just once and all the frameworks could use them. Second, I think there could be use for a common low level display framework. Currently the lower level code (display HW handling, etc.) and higher level code (buffer management, policies, etc) seem to be usually tied together, like the fb framework or the drm. Granted, the frameworks do not force that, and for OMAP we indeed have omapfb and omapdrm using the lower level omapdss. But I don't see that it's anything OMAP specific as such. I think the lower level framework could have components something like this (the naming is OMAP oriented, of course): overlay - a hardware "window", gets pixels from memory, possibly does format conversions, scaling, etc. overlay compositor - composes multiple overlays into one output, possibly doing things like translucency. output - gets the pixels from overlay compositor, and sends them out according to particular video timings when using conventional video interface, or via any other mean when using non-conventional video buses like DSI command mode. display - handles an external display. For conventional displays this wouldn't do much, but for complex ones it does whatever needed by that particular display. This is something similar to what DRM has, I believe. The biggest difference is that the display can be a full blown driver for a complex piece of HW. This kind of low level framework would be good for two purposes: 1) I think it's a good division generally, having the low level HW driver separate from the higher level buffer/policy management and 2) fb, drm, v4l2 or any possible future framework could all use the same low level framework. --- Now, I'm quite sure the above framework could work quite well with any OMAP like hardware, with unified memory (i.e. the video buffers are in SDRAM) and 3D chips and similar components are separate. But what I'm not sure is how desktop world's gfx cards change things. Most probably all the above components can be found from there also in some form, but are there some interdependencies between 3D/buffer management/something else and the video output side? This was a very rough and quite short proposal, but I'm happy to improve and extend it if it's not totally shot down. Tomi

Re: Debian GNU/Linux on tablet hardware

by Zygmunt Krynicki

W dniu 28.10.2011 17:46, Jeremiah Foster pisze: >>> >>> Android's Linux kernels are supported (maintained?) by Linaro. >> >> With my Linaro hat on I must object. Depending on what you meant the statement above is either highly inaccurate or simply untrue. > > Hence the question mark. :) I think what I originally meant is that we don't focus solely on Android. "Improved" is the word I would use, that implies neither support nor maintenance as we are between the vendors (that are also part of Linaro) and upstream kernel community (that we are a part of) and we have no control of either side and their actions. As to what we do check our FAQ (http://www.linaro.org/faqs/) and read on. >> Android kernel situation is complicated and varies per board/SoC. What Linaro does is try to upstream and unify the kernel for Linaro member companies SoCs. > > What does that mean in practice? Disclaimer: I'm not a kernel developer. I have experience in the non-Intel part of the world but I'm not the sort of person with up-to-date hands-on experience. For those folks please look at traffic in linaro-dev(a)lists.linaro.org and at our patchwork instance at patches.linaro.org. You can see what kind of patches we push upstream and if they have landed yet. As for your question, read on. A lot of ARM devices have a BSP kernel (android or not) that is prepared by some 3rd party (sometimes also by the vendor themselves if the device is a clone of the reference design) and that kernel is generally not pushed upstream. This affects, by far, the vast majority of devices out there (I'd say that nothing gets pushed by those companies simply because their work mode does not require such a step - we are working on educating them in the benefits of working both towards products and common code base). The ARM tree in the upstream kernel is, again, by far, the largest of all the other architectures. If I remember correctly it is in fact larger than *all* the other trees combined. The reasons for this are complicated but can be generally simplified to code duplication between the different devices and greater diversity in the actual hardware as compared to other platforms. To get ARM Linux healthy we need to reduce that clutter and make sure that support for the latest and greatest hardware is upstream quickly and the code is being actively maintained by everyone. >> This is far from finished and uniform. The "BSP" kernel that hardware vendors provide is not supported by Linaro and in fact often contains code that cannot go upstream. > > What does it use this proprietary code for? To know the APIs or to get other hardware interface info? Isn't that a little risky? Won't proprietary, and potentially patented IP leak into the Linaro work? (Not that I believe in IP.) The term proprietary is a bit misleading, the code IS released as GPL. It is simply there to support some parts (often userspace or "firmware") that is not open sourced and cannot be for all practical considerations. As for the patches in general, there are different reasons why they are not suitable for being proposed and included upstream: 1) Shabby code, against old trees, copy-pasted from another similar device, maintenance hell. This is, by my unqualified judgment, the vast majority of the problem. 2) Code that has no good place in the kernel just yet because the kernel interfaces are insufficient for the extremely complicated world of ARM SoCs. Off the top of my, unqualified, head: power management, memory management, everything related to graphics and probably many more. Here the reason for not being upstream is that there is no consensus on how to do something (how to support a certain class of SoC components) that could be applied to many vendors and non-arm world as well. Here the people that write the BSP cannot solve the problem and just implement their own solution to meet the deadline. Such code is often very good but there are many similar solutions that are quite nontrivial to merge into one sensible codebase. One such example is memory management where we have no less than 3 or 4 competing interfaces from various companies and there is a working group inside Linaro and the greater Linux community that tries to solve this problem. 3) Bits that enable proprietary userspace drivers. The reasons are obvious. This could be related to lots of different things, not only graphics as people often think. IP and software edge (optimizations that make otherwise identical hardware perform better than competition) is probably a big motivation here. The IP protection is not only used as in "don't steal our stuff" but rather "hey, with this being binary it is harder to prove that we violate a specific patent you have". In retrospective this is a thing those companies obviously need. Just look at how many Android handset vendors pay to, for example, Microsoft, for patents that allegedly apply there. The world of graphics is riddled with patents and I'm sure that a big money-laden hardware vendor is a good target for whoever owns the patents. >> Linaro has several trees, including a grand unification tree that tries to support all the member companies chips in one tree (and one binary, thanks to device trees) but this effort is years away (my personal estimate, I don't speak for the organization). In addition we have several trees for normal/androidized kernel for each board. In the latest 2011.10 release hardware was not supported in 100% on any board that I'm aware of. >> >> Having said that the term "supported" seems inappropriate to me. We do work on those boards though. > > How would you define it? By "work" I meant "we are *working* on making the kernel and userspace on those boards better in each release". Better is shared amongst: 1) More patches landed upstream, thus less delta. 2) Less duplication within the kernel (better code), more device tree usage, closer to having one kernel binary that supports several different boards. 3) Better power management, stability, performance, more features, bells and whistles. 4) Less delta from the android variant to the normal variant. More discussion and more consensus on how to join the two worlds. And let's not forget, my own personal favorite, more validation. The code is tested both manually and automatically and the scope, coverage and quality is pushed forward each time. >>> Anything that runs Android can run GNU/Linux. >> >> This is a gross oversimplification IMHO. You usually get androidized BSP kernel from a few months/years ago with binary parts that have no corresponding source code. Good luck booting vanilla kernel there. > > But it appears to me that all the official boards that are targets for Linaro can run a vanilla kernel, is that not the case? If not, what BSP stuff are you referring to - graphics acceleration? No I don't think that is the case. A quick glance at http://git.linaro.org/gitweb will show you how many trees we have. Except for the explicit upstream trees that Nico maintains none of the important changes in other trees are upstream today (at least not yet). Even the Linaro various kernels (which are _not_ the BSP kernels) fail to work sensibly on all of the boards today. Next-gen boards are usually the ones with weakest support (although that is rapidly changing, thanks to what we are doing). Often most primitive board features work (like, it kind of boots with a specific boot loader and the CPU runs) but anything you definitely want those boards to do: power management, stability, sound, graphics, 3D & multimedia, wifi/bluetooth, FM radio, GPS(?), DSP suppoet, ARMv7 optimizations, is simply not there. Best regards ZK PS: I think that you should ask those questions on @linaro-dev. I could be talking nonsense here and the people that really know simply did not see this message. Therefore I'm cross-posting to linaro-dev.

[ANN] Android Build downloads and other improvements

by Paul Sokolovsky

Hello, There were few user-facing improvements for https://android-build.linaro.org/ , Linaro Android Build System, from which can be downloaded daily builds of Android components (platform, toolchain): 1. HTTP downloads were enabled. It was long-standing feature request, and brings number of improvements to user experience and system scalability: a) With 100Mb+ downloads android-build.linaro.org provides, going plain HTTP instead of SSL improves download speed pretty well. b) Taking into account that downloads are server by not very powerful EC2 instance, alleviating it from SSL number-crunching improve concurrent download speed and build performance. c) Using plain HTTP gets around SSL certificate issues, the need to do extra click-thru in browser or use obscure options for wget. 2. HTTP downloads made default for the Build Frontend. Instead of documenting HTTP download link on some obscure web page, they were made default when browsing build results from https://android-build.linaro.org , e.g.: https://android-build.linaro.org/builds/~linaro-android/staging-panda/ (Please note that all older links will keep working. Underlying Jenkins instance also keeps using https:// links). 3. MD5SUMS are available for platform downloads. Now it's easy to verify integrity of downloads using well-known convention of MD5SUMS files. Whole download and integrity checking can be scripted as: wget -r -nd http://android-build.linaro.org/builds/~linaro-android/staging-panda/65/tar… md5sum -c MD5SUMS 4. Links to easily access build logs in several formats added. Last milestone, we enabled Jenkins Log Parser plugin, which allowed to get quickly to the location of errors within 20MB build log file. However, it was available only from within Jenkins. Now, links to the most useful log browsing pages were added directly to frontend's build page, following concept that frontend page should make the most useful build information available and developers' fingertips. Now there're (under "Log" subsection on the page): * Parsed - parsed log mentioned above, providing quick jump to error locations and stats about a build * Tail - Last 500KB or so of the log, which oftentimes contain error. With one click, entire log can be browsed, with all lines still nicely wrapped. * Raw - plain-text log, as available before. This is mostly suitable for download and local view, as lines are not wrapped in most browsers when viewing online. See https://android-build.linaro.org/builds/~linaro-android/staging-panda/#buil… for example. -- Best Regards, Paul 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
