[ACTIVITY] Graphics WG status report - wk35.2011 (20110829-20110902)

by Ilias Biris

Status: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/WeeklyReport Wk 35 weekly meeting minutes: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Notes/2011-08-31 Highlights: - Many on vacation or national holiday for part of last week - less action ongoing - LP: started working with the backlog milestone on the LP Graphics projects. Transition ongoing to move the backlog as blueprints under the backlog milestone of each project - Main highlight - retrospective with regards to Unity/NUX/Compiz support in LEBs. In summary the decisions taken were ++ Start a regular communication with the maintainers of these three components + Ubuntu team to gauge what is coming as well as to ask how to best get our components code upstream. Due to Oneiric there is not much upstreaming happening on the Ubuntu side. The calls already started (weekly calls) ++ For GWG this means we also shift our focus to the Oneiric development builds, whilst tackling on case by case any issues with the natty-based LEBs Please see the status report for more details Thanks, -- 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

[ACTIVITY] Multimedia WG status report - wk35.2011 (20110829-20110902)

by Ilias Biris

Status report in https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport Last week's meeting notes in: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-08-30 == Highlights (details in the status report link above) == - the 1109 planned deliverables are in : https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/WeeklyReport#mu… - LJT support for Android has been announced. The existing code needs to be broken into smaller patches to be sent upstream. Backlog in https://launchpad.net/libjpeg-turbo/+milestone/backlog contains a number of blueprints related to that work - bugs work is ongoing: https://bugs.launchpad.net/linaro-ubuntu/+bug/816638 - the kernel side seems to be fixed, looking at the pulseaudio/alsa side of the bug now https://bugs.launchpad.net/linaro-ubuntu/+bug/760919 - patch created and posted https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/746023 - being worked now https://bugs.launchpad.net/ubuntu/+source/linux-linaro-omap/+bug/733334 - probably a duplicate of 746023 - UCM integration is now being tested. Snowball related testing for UCM configuration support may be postponed for after 1109 as snowball ubuntu support for audio still has issues - there is no easy way to test UCM there Please contact me if there are questions, or if you spot something odd/missing in this status report.

Gerrit refs regexp patterns don't work - usefully or at all

by Paul Sokolovsky

Hello, We're elaborating our Linaro Gerrit (2.2.1) set up, and would like to enforce separation between upstream and "our" branches, to disallow stray commits to upstream branches and keep them pullable from AOSP. So, we'd like to limit review requests, pushes, etc. to "refs/heads/for/linaro*" and "refs/heads/linaro*". Trying to enter exactly that into refs entries for All Project's ACL lead to "Invalid Name" error. After looking at Gerrit's source, it turns out that Gerrit expects *-using pattern to end with "/*". Well, why? Yes, it's nice idea to use hierarchical-like branch names. Sometimes. But there're also good reasons to restrict branch name to generic "identifier". For example, to keep one-to-one mapping with filenames (confined to some dirs), or database names (both useful for CI for example). So, requiring slash present before "*" seems like arbitrary restrictions. Anyway, I wasn't too upset, knowing that arbitrary patterns can be encoded using regexps, and that's where real surprises start. First of all, looking at example regexps at http://gerrit.googlecode.com/svn/documentation/2.2.1/access-control.html#_p… there were suspiciously stray backslashes in pattern examples. Anyway, I tried to input "^refs/heads/linaro.*", it was rejected with "Invalid Name" error. Same for "^refs/heads/linaro.*". Then I just tried example from the doc, both as is and with slashes stripped - "\^refs/heads/[a-z]\{1,8\}" & "^refs/heads/[a-z]{1,8}". Same error. Looking at the source, validation for regexp case is complicated (and nothing points to backslashes being required): it seems to generate a subject string which would match entered pattern, and test that simple for being good refs syntax. Well, I thought, maybe UI validation outslies itself, and commit changes directly to project.config of refs/meta/config branch of All-Project. No avail. With config like: [access "^refs/for/refs/linaro.*"] push = group Registered Users it's not possible to submit review against any branch at all. Thinking here would be that may be regexp library is not available, or regexp syntax is not enabled by some option, but just searching reviews with queries like below works just ok: "project:^platform/buil. status:open" "project:^platform/buil.* status:open" "project:^platform/buil.+ status:open" So, I'm stumbled here - what could be wrong, and where to look next?

ARM CPU part numbers

by Andrew Stubbs

Hi all, I'm currently trying to get GCC to auto-detect what CPU to optimize for by finding out what CPU it's actually running on (the user would only have to pass -mcpu=native). It does this simply by reading /proc/cpuinfo. The problem is finding what magic numbers correspond to what CPU. I've found the numbers for A8 and A9 empirically, but I'd like a longer list than that! Does anybody have a list of such numbers? Or else, perhaps people could just post any number they happen to know? I do have a few devices other than A8 and A9 lying around I can look at, but the problem there is I don't actually know for certain what exact CPU model those numbers map to, so confirmed numbers only please. Thanks Andrew
