Linaro Release 11.12 Postmortem summary

by David Zinman

Hi All, Here is the summary for Linaro release 11.12 postmortem and lessons learned, and the last for the calendar year. For a detailed release review please visit https://wiki.linaro.org/Cycles/1112/Release/Review Highlights and Key Successes ============================ This cycle's release features accelerated graphics for Android Ice Cream Sandwich on several of our supported member platforms. http://www.linaro.org/accelerated-builds-of-android-ice-cream-sandwich-now-… The Youtube videos have been making the rounds in various social media spots: http://www.youtube.com/watch?v=XPFy2MFbUys&feature=youtu.be http://www.youtube.com/watch?v=whpaltVa3pQ&feature=youtu.be http://www.youtube.com/watch?v=7_MCLKmXDFA&feature=youtu.be Other than ICS the Android team has integrated DS-5 with Gator and libjpeg-turbo support. An AOSP master build is also available. The Ubuntu Platform team has integrated continuous integration (CI) scripts to automatically generate linux-linaro and lt-panda kernel packages. The preview images for Ubuntu 12.04, Precise Pangolin are available and include nano, developer, server, alip (Xfce desktop based), and ubuntu-desktop. For more information on release highlights please see our release page: https://wiki.linaro.org/Cycles/1112/Release Postmortem and Lessons Learned ============================== Congratulations to the release team for getting this release out on time with little thrashing at the end of the cycle. One item that has contributed to that was the initiation of a weekly platform - landing team meeting where issues with high priorities are discussed between the groups. Near the end of the cycle short stand-up meetings are held for any last minute issues that arise. This has been a good success so far and a similar weekly meeting between the platform and working groups is planned for the new year. The addition of the community specialist (Amber Graner) was extremely helpful to keeping the release on track and on time. Some of the lessons learned that came out of the cycle are: * Talking directly to members and communities is very beneficial to Linaro. * When creating blueprints, due diligence is required to scope and schedule it properly. * Integration with components should happen at the earliest possible moment to allow time for re-spins and bug-fixing. * Use the project manager as a resource to help with the release process. -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs

Announce: Panda ICS SGX 1.8 on tilt-android-tracking

by Andy Green

Hi - Mainly due to the extraordinary efforts of Jassi, I'm pleased to announce TI LT now has a mostly-workable initial build of tilt-android-tracking for ICS including SGX 1.8 driver, on 3.2-rc5 basis. It has two issues at the moment to be aware of: 1) We were only able to get it to work right now on Build #1 of the Panda ICS rootfs. Build 4 is giving some problem with struct size matching in dsscomp. Jassi had read something about it on linaro-android and expects it'll be solved soon. 2) Display is from HDMI, is coming at 1080p, but we have a 640x480 box in the top left right now with the content. I understand AOSP is only coming at 640x480 anyway from HDMI anyway. We also hope to fix this shortly. It's important to note this is now stitched into its own topic (tracking-topic-sgx-1.8) and follows our normal flow of vanilla tracking + sgx-1.8 + androidization, ie, it's under control for ongoing tracking like the previous sgx topic was (which we successfully provided for 5 months or so for Gingerbread) and not just a bolt-on. Hopefully this will reduce the amount of Linaro effort wasted off-piste... -Andy -- Andy Green | TI Landing Team Leader Linaro.org │ Open source software for ARM SoCs | Follow Linaro http://facebook.com/pages/Linaro/155974581091106 - http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog

Updated Pulse Audio + alsa-lib for 11.12

by Tom Gall

Hi Ricardo, With working HDMI output on the original panda board, and Wei's new release of patches to alsa-lib and pulseaudio, I've updated both alsa-lib and pulseaudio for 11.12 in ppa:linaro-maintainers/overlay. Sound on the panda over HDMI from my testing works out of the box. It's not perfect but it works. I will repeat this same test with my imx53 shortly. For all on the dev list, be aware that audio is in a state of flux and while we'd like to avoid defects they are likely. The Multimedia WG is putting substantial effort into having a "just works" level of quality for supported boards. A very bit thank you is in order for Wei Feng for his hard work on 11.12! Good job! One small sound for an ARM board, but a big noise for Linaro when we can say, "It just works." -- Regards, Tom "Where's the kaboom!? There was supposed to be an earth-shattering kaboom!"

Linaro Android testing for Pandaboard

by Alan Chuang

Hi All: Since Panda board is now officially supported by Google, I decided to do a quick testing between Linaro build (release 11.11 - v2.3.7), Linaro ICS preview (v4.0.1) and Google's ICS build for Panda-board (v4.0.1). Here are what I found: 1. Google's ICS build detects the resolution to be 672(H)x1280(W) on my monitor while Linaro builds default to 480x640. I manually changed the screen resolution in boot.scr to be omapfb.mode=dvi:1280x672MR-24@60. The linaro ICS preview can now come up with 672x1280 resolution, but I encountered graph driver crash in 11.11 release (v2.3.7). The video output came out on HDMI port for 11.11 release instead of DVI port as in Linaro ICS previous & Google's ICS build. This seems to tell me that there is a problem with graphic driver in 11.11 official release and EDID detection is not working for Linaro builds. 2. I ran Sunspider & 0xbench in Linaro ICS preview (in 480x640 resolution) & Google's ICS build for Panda-board (in 1280x672 resolution). Linaro ICS preview has slightly better result in Sunspider testing, but falls significantly behind in 0xbench. Changing the resolution to 1280x672 on the Linaro ICS preview build shows noticeable lag in UI performance. This seems to suggest that Linaro ICS preview doesn't enable GPU. I simply followed the instructions in the release note to populate SD cards with proper images for testing. Has anyone done similar testing? Is the above observation consistent with your result?

[ACTIVITY] Status of memory management closing 11.12

by Ilias Biris

Hi folks, I went ahead and checked what is the status of the UMM effort as 2011 is closing to an end. What follows is my attempt to summarise the status, collating the pieces from the latest announcements and changelogs and having discussed it briefly with Jesse and Rob. Feel free to comment if there is something missing or not correct: A. CMA - Contiguous memory allocator. This is in its v17 incarnation at the moment (a v18 is in preparation but not released yet). v17 shares the code with memory compaction subsystem, not the hotplug like it was before (change has been suggested by Mel Gorman) and there are also a few fixes here and there, like addressing most of the comments from Andrew Morton and Mel Gorman in the rest of the CMA code, fixing broken initialization on ARM systems with DMA zone enabled and rebasing the code on v3.2-rc2 kernel. An issue has been noted in linaro-dev from the TI landing team : without any highmem the code is working great, but with HIGHMEM inclusion of the CMA v17 consistently causes failure during DMA init. This is expected to be fixed soon (perhaps in v18?). In meantime it is suggested using 2G/2G memory split as a workaround (Kernel Features -> Memory split -> 2G/2G user/kernel split). B. dma mapping API - DMA-mapping framework redesign for ARM architecture: this is in the v4 now. It includes a few minor changes since last version. The changes are mainly on the IOMMU mapper, keeping the DMA-mapping redesign patches almost unchanged. The code is rebased onto v3.2-rc4 kernel + IOMMU/next branch to include latest changes from IOMMU kernel tree. This series also contains support for mapping with pages larger than 4KiB using new, extended IOMMU API, and did a general cleanup of the DMA mapping implementation. However it seems that this patchset "attempts to fix everyone at once". It has been suggested that instead of trying to do that the implementation should give sufficient transition period - for example just adding the new methods now and only removing them in the following merge window when all the architectures have had a chance to migrate. C. dmabuf - a DMA-buf object sharing framework: this is now in its 3rd version. The newest version incorporates changes as requested during the review, such as - replacing BUG_ON with WARN_ON at various places, removing mmap() fop and dma_buf_op, also the sg_sync* operations, and documenting that mmap is not allowed for exported buffer, adding error checks, replacing EXPORT_SYMBOL with EXPORT_SYMBOL_GPL and fixing some cosmetic/documentation items. There are still some items under discusion such as userspace mmap support, more advanced (and more strictly specified) coherency models and shared infrastructure for implementing exporters. However, there is a suggestion that these items will become much clearer once we have a few example drivers at hand and a better understanding of what cases need to be handled better. D. Finally some repositories - where can you find the code to try it out: * git://git.linaro.org/people/jessebarker/linaro-mm-sig/linux.git contains (for the moment) 6 branches: + cma-v17 == unadulterated v3.2-rc4 + cma v17 patchset + dma-mapping-v4 == unadulterated v3.2-rc4 + dma-mapping v4 patchset + android-cma-v17 == john stultz's androidization tree based upon unadulterated v3.2-rc4 + cma v17 patchset + android-dma-mapping-v4 == john stultz's androidization tree based upon unadulterated v3.2-rc4 + dma-mapping v4 patchset Also note these repos: - https://github.com/robclark/kernel-omap4/commits/drmplane-dmabuf contains patches to enable sharing of buffers between drm and v4l2, Rob commented that it isn't really identified yet which tree to push dmabuf through.. airlied has volunteered to push via drm tree, which is ok - git://git.linaro.org/people/bgaignard/linux-snowball-cma-test.git contains a first version of the CMA testing scripts for LAVA (snowball specific at least for now) Best regards, -- Ilias Biris ilias.biris(a)linaro.org Project Manager, Linaro M: +358504839608, IRC: ibiris Skype: ilias_biris Linaro.org│ Open source software for ARM SoCs

[ANN] Automated upstream syncing for Linaro Android tree

by Paul Sokolovsky

Hello, This should have gone more than a week ago, but was "lost" in click-thru work. Anyway, we now finally have automatic syncing with upstreams for our tree - that includes AOSP and other components we mirror. It runs for more than 2 weeks now and works pretty well. For AOSP, some components may be missing with upstream version upgrades, then just please submit a ticket to have them picked up (manual op), like this one: https://bugs.launchpad.net/linaro-android-infrastructure/+bug/905664 to ensure timely processing. Thanks, and Merry Christmas!

Is Pandaboard cpuhotplug working stably?

by Barry Song

Hi guys, i tried cpuhotplug on pandaboard for both Pandroid_Froyo_L27.8.2_release_pkg and Linaro 11.11. It has failed to work stably. On Pandroid_Froyo_L27.8.2_release_pkg, unplugging cpu1 works well: # echo 0 > /sys/devices/system/cpu/cpu1/online CPU1: shutdown if i enable the cpu1 again by "echo 1 > /sys/devices/system/cpu/cpu1/online", the system will restore to 3 random status: hang, normal, panic. Using Linaro 11.11 release, "echo 0 > /sys/devices/system/cpu/cpu1/online" will make system hang and the whole system will not be able to reset by pressing reset key, the only way to reset system is pulling out AV power. i am sorry i can't get more time to debug and find more clues. just want to ask people whether this is a version the cpuhotplug works normal on? Thanks barry
