Hi, I am currently working on Pandaboard and want to make PMU interrupt work. I notice that you have a patch to enable pmu/perf support on OMAP4: http://lists.linaro.org/pipermail/linaro-dev/2011-April/004019.html Can you please tell me on which code base of the kernel the patch is working? I am using minimal FS on pandaboard. But the patch does not work. I find the PMU interrupt is not triggered. Thanks a lot in advance. Ye Fan

hackbox will be rebooted on Friday, 2011/11/11 (how cool is that date eh?) at 11:11 UTC

by Zach Pfeffer

We're going to upgrade the hackbox on Friday, which means a reboot. As we've always mentioned the hackbox doesn't get backed up, so everything in /mnt/user will be nuked. Please back anything you care about up. Danilo, If we can get a list of files together, would you be able to set up a backup restore mechanism for those files? The only file on the list right now would be /home/ubuntu/.ssh/authorized_keys -- 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

[ACTIVITY] Multimedia WG weekly status report - wk46.2011 (20111107-20111111)

by Ilias Biris

Detailed status report - with working links: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Week 46 meeting notes: = Highlights = - Speex is back in the radar following requests coming from Android to provide a NEON optimised version. Deliverables arranged for 11.11 and 11.12. - libpng: NEON auto detection is now implemented at a local patch which will go into the Ubuntu LEB for 11.11. - libjpeg-turbo: moving forward with the actions at Connect. The first list of actions are reflected in the blueprints targeted for 11.11, such as updating libjpeg-turbo packaging to include libjpeg8 support, and collecting tjbench performance information - Alsa UCM for PA: the work aims to provide a more natural natural fit of alsa UCM concepts to Pulseaudio core concepts. The work continued post-LC with a look at the contributed upstream patches (intel-origin) which seem to be partly driven from a need to handle policy and also partly originating at the jack detection discussion and patches upstream. The investigation there is ongoing, but a list of findings are put together in the MMWG UCM for PA analysis page. But at least for 11.11 a release containing the patches Wei has been putting together which do the mapping in a more PA agreeable way will be made available. - UCM for Android phase 1 has started and will be hopefully at a good shape for the 11.12 release - End2End testing: the basic case of end2end testing for audio will be ready for 11.12 - From UMM side: + Debug and tracing patch for CMA has been contributed thread on linaro-mm-sig) + Following the dri2video on xf86-video-nouveau reference implementation for dri2video effectively employing the UMM work that has been going on. Most of the dri2video stuff is implemented plus a simple test app in libdri2. The nouveau reference prototype seems to have reached a good point to allow sending patches after some cleanup. This will be officially ready during 11.12 Questions, comments, other feedback are welcome. -- 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

important oneiric daily snapshot change

by Tom Gall

Hi All, As a result of bug https://bugs.launchpad.net/linaro-ubuntu/+bug/890185, it was decided to enable a default password on images going forward. The released snapshots now use the password "linaro" for the linaro account. Auto login behavior for the serial cons as well as the graphical cons via lightdm for those images that use it should be otherwise unchanged. -- Regards, Tom "We want great men who, when fortune frowns will not be discouraged." - Colonel Henry Knox Linaro.org │ Open source software for ARM SoCs w) tom.gall att linaro.org w) tom_gall att vnet.ibm.com h) tom_gall att mac.com

dependencies between actions in the dispatcher

by Michael Hudson-Doyle

Recently I've been thinking about the dispatcher a bit (as other mails should have indicated) and I've gotten to think about dependencies between actions. If you don't already know, a dispatcher job file mostly consists of a list of actions to execute, for example: "actions": [ { "command": "deploy_linaro_image", "parameters": {"rootfs": "...", "hwpack": "..."} }, { "command": "lava_test_install", "parameters": {"tests": ["stream", "ltp"]} }, { "command": "boot_linaro_image" }, { "command": "lava_test_run", "parameters": {"test_name": "stream"} }, { "command": "lava_test_run", "parameters": {"test_name": "ltp"} }, { "command": "submit_results", "parameters": { "server": "http://localhost/lava-server/RPC2/", "stream": "/anonymous/test/" } } ] I hope what the actions do is reasonably clear from their names. What is easy-ish for us, but probably rather harder for a computer program to do is to see the data dependencies between the different actions. boot_linaro_image makes no sense if deploy_linaro_image failed. Running tests with lava_test_run doesn't make sense if the test failed to install (or if boot_linaro_image failed). But the lava_test_run's are independent, even if the stream test hangs we could still run the ltp tests. And we should always submit the results, that's a kind of special case (and I'm not sure submit results should really be an action). It seems like the way we (aim to, at least) handle this isn't too bad: basically any action can veto the running of any more actions (apart from the special case of submit_results). But there's more than control flow going on here -- there is data flow too. The reason I'm writing this mail is that I'm working on testing images in qemu[1]. If we want to use a similar layout of the job files (and I think using the same commands even will be possible), then we'll have an action that builds an image and another that starts up qemu. The action that starts up qemu needs to know where the previous action is! And of course I've been a bit sneaky here, because there's another, very important kind of data that needs to move around: the test results. Currently we assume that all the test results end up in a particular directory (either on the device (for ubuntu-based tests) or on the host (android-based tests)). This feels a bit grotty to me, and will need to change for tests run under qemu and possibly for the multi-system tests that were discussed at the connect. There is an object in the dispatcher -- the context -- that encapsulates the state that persists through the run, so this is probably where the data should live -- we could have a dictionary attached to the context and then deploy_linaro_image for a qemu client type could stuff the path into this and the boot_linaro_image action for a qemu client could read this path (and complain appropriately if its not there). Additionally we could have a list of 'result locations' (could be filesystem paths on the host, or locations on the linaro image) and the submit results step could read from here to gather together the results. This feels like it will work, but is still a bit implicit -- it's still not obvious that boot_linaro_image depends on something deploy_linaro_image does -- but maybe this is information that should be maintained outside in the job file, maybe in a JSON schema for job files? Apologies for the second brain dump today. I think these are the changes I want to make: 1) Change submit results to not be an action. 2) Add a result_locations list and action_data dictionary to LavaContext. My half-thought through idea is that actions will use the action name as a prefix, e.g. deploy_linaro_image for a qemu client might set 'deploy_linaro_image.qemu_img_path' in this dict. 3) Change the lava-test and lava-android-test to store into result_locations and the submit step to read from there. 4) Use action data to have deploy_linaro_image and boot_linaro_image (and maybe lava_test_install and lava_test_run) talk to each other. What do you guys think? Cheers, mwh [1] testing in qemu is perhaps not incredibly useful for us, but doing this forces me to confront some of the issues with testing images with in a fast model, which is something we really want to do, as we can get access to the fast model of the cortex-a15 long before we'll get access to hardware

Freeze date for the Linaro 11.11 kernel release

by Nicolas Pitre

We are considering freezing the 11.11 kernel this next Monday (Nov 14) in order to release it on Wednesday (Nov 16), so it is out there before the US Thanksgiving holiday. If anyone would like to see their patches included in the Linaro kernel for this month, please consider submitting them ASAP. As discussed in Orlando, we are also considering a shift towards using the latest tagged release from Torvalds' mainline tree. This process is not fully in place yet, so the regular Linaro release based on the latest stable upstream release will still occur for this month. Nicolas
