Important: Reservation details for Linaro Developer Summit in Budapest, 9-13 May

by Stephen Doel

Hi All, I want to bring to your attention some important logistic points around the Developer Summit in Budapest from 9 - 13 May ( https://wiki.linaro.org/Events/2011-05-LDS) 1. Please register your attendance now: https://forms.canonical.com/udsreg/ . I'd like you to do this even if you haven't yet booked your flights and so on, as we're using this attendee list to drive a lot of our planning for the week 2. You must make a room reservation at the hotel before* 8 April* to benefit from our discounted rates, and to ensure you're staying where all the action is happening ( https://wiki.linaro.org/Events/2011-05-LDS#Hotel%20Booking) 3. Bookmark https://wiki.linaro.org/Events/2011-05-LDS and check it regularly, as we will grow the amount of information there to explain what's happening and how to get the most out of the Summit as we get closer to May (I'll also send periodic e-mails to update you all) -- Thx Stephen Doel Linaro Ltd Chief Operating Officer +44 77 66 014 247

Free (as in freedom) website graphics traces

by Alexandros Frantzis

Hi all! Web browsing is one of the most common and important activities performed on modern consumer mobile devices. As such, it receives special attention in our benchmarking blueprint. In order to have reproducible and automatic benchmarking for web browsing, we need to acquire graphics traces for browsing sessions that can be played back at a later time. Both cairo (used in Gecko and WebkitGtk) and Qt provide mechanisms for performing graphics operation capture and playback. Unfortunately, due to copyright restrictions, we are only able to redistribute traces captured from websites that license their content under a Free license. We have set up a wiki page that contains a preliminary list of websites that we can use in this way: https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/Docs/WebsiteTraces Please feel free to add any other websites that are suitable for this purpose. Furthermore, to assist with website trace capture we have created a set of tools that load and scroll a set of webpages using the most common rendering engines. There is currently support for Gecko, WebkitGtk and QtWebkit. These tools may prove useful for other groups, too. You can find more information in the wiki page linked above. Thanks, Alexandros

linaro-omap kernel 1003.6 boot failure

by Turgis, Frederic

Hi, (writing from my work address as frederic.turgis(a)linaro.org lost password is still not reset ;-) ) To perform some systemtap checking, I need kernel package with debug symbols, which is available in 1003.6 version from http://ddebs.ubuntu.com/pool/universe/l/linux-linaro-omap/ So I did some apt-get update, install linux-image-2.6.37-1003-linaro-omap followed by flash-kernel 2.6.37-1003-linaro-omap. Boot fails at some point (before setting up omap_hsuart in an OK log from 2.6.37-1002) Any known issue or thing I am doing wrong ?

[PATCH] ARM: Samsung: change suspend/resume code to depend on CONFIG_SUSPEND

by amitdanielk＠gmail.com

From: Marek Szyprowski <m.szyprowski(a)samsung.com> Most suspend/resume code depends on CONFIG_PM. This causes problems if one wants to enable Runtime PM (to control power domains for example), but doesn't need system suspend/resume feature. This also enables to use Runtime PM feature on S5PV310 which doesn't implement system suspend/resume callbacks yet. Signed-off-by: Marek Szyprowski <m.szyprowski(a)samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park(a)samsung.com> Tested-by: Amit Daniel Kachhap <amit.kachhap(a)linaro.org> --- Sending this patch to linaro mailing list as it is needed for linaro kernel(2.6.38) to enable PM_DEBUG flag and debug clock domains (launchpad bug id:713075).

Minutes & Actions: Toolchain Working Group meeting of Feb 21, 2011

by Mounir Bsaibes

Enclosed you'll find a link to the agenda, minutes and actions from the Linaro Toolchain working group weekly meetings of Feb 21, 2011. https://wiki.linaro.org/WorkingGroups/ToolChain/Meetings/2011-02-21 == Summary == * FSF Copyright assignment is now in place * GCC 4.6 build and test complete, pushed an updated to the bzr branch, the branch is now up to mainline state as of the 12th. * Submitted PR46178, PR46002 patches the first already approved and committed. * Tracked down the problem causing serial console to break: the new Linux driver uses some extra features of the UART which we weren't modelling. * Merged, reviewed and submitted many patches related to correctness. * Investigating developer tools: looked into what people use, looked into alternatives to ltrace as it has issues on many platforms. latrace looks quite good on ARM. * Implemented missing epoll syscalls for qemu usermode and submitted upstream * Identified root cause of GDB problems running on Versatile Express in SMP mode, and verified that Errata workaround fixes the problem * Finished testing GDB HW watchpoints patch on vexpress, submitted complete patch set for mainline inclusion * Will provide a patch to override some string routines in Ubuntu, and then consider pushing elsewhere * Looking at Versatile Express QEMU to get Linaro kernel booting Regards, Mounir

by Tom Gall

Enclosed you'll find a link to the agenda, notes and actions from the Linaro Developer Platforms Weekly Status meeting held on February 23rd in #linaro-meeting on irc.freenode.net at 16:00 UTC. https://wiki.linaro.org/Platform/Foundations/2011-02-23 Actions from the meeting where as follows: * tgall_foo and JamieBennett to get linaro-ubuntu building in Offspring * ppearse to investigate how libtool does ldopen for GObject Introspection work * slangasek, JamieBennett to shake the tree for developer image testing I did not discover until this morning that Mootbot didn't capture the entire log of the meeting and I am quite sure a couple of actions have been lost as a result. Please edit the page is you know of an action that should be there.
