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

Emdebian sprint - flash-kernel discussion

by Loïc Minier

Hi there flash-kernel is this place where we add support for a lot of weird boards of various architectures. "flash-kernel" because it used to just write a kernel to Flash memory, but that's not always true anymore. Because it's integrated in d-i and with initramfs-tools / linux packages, it is the easiest way to add support for one new board. But flash-kernel isn't in the happiest state right now, as new boards were added by copy-pasting the installation logic of other boards over and over. Also, Ubuntu added more and more boards and features to its flash-kernel package, and the delta is really big now (I will take part of the blame for allowing this to happen). In the light of this situation, and because I think Debian and derivatives will support more and more boards via flash-kernel in the future (for instance modern ARM boards in the armel/armhf ports), I'm interested in improving flash-kernel's code, architecture and scalability (in fact, I started working on it [1]). I'm at the Emdebian sprint in Cambridge this week and I wanted to pursue work on flash-kernel this week, but a lot of people here would like to have a discussion on this work, and other people seem to be interested in solving the same problems in flash-kernel. So in the interest of avoiding work duplication and in the hope to come up with a good roadmap and target architecture for flash-kernel, I'll be hosting a discussion on flash-kernel development tomorrow morning at 11am UK time. (Sorry for the late notice!) If you're interested in flash-kernel, if you have ideas, patches, etc. consider dialing in! Of course, email works too. I'll work on a wiki page summarizing tomorrow's discussion and the plans around flash-kernel.

Cheers, [1] branch at http://git.debian.org/?p=users/lool/d-i/flash-kernel.git * adds a testsuite * consolidates code into functions * moves board support data into a database (currently inline for convenience of testing, but will be split out in its own file) -- Loïc Minier

Thumb-2 kernel tree

by markos.chandras＠gmail.com

Good evening, First post on this list so I apologize in advance if I post on the wrong list. I am desperately looking for a working thumb-2 kernel tree. I am currently using the dirty/arm/omap-thumb2+merged branch from git://git.linaro.org/people/dmart/linux-2.6-arm.git repo, since it is the only one that compiles for me. However, to my understanding, this is not a very 'safe' branch to use on daily basis. Is that true? Is there a more 'stable' git branch which I can compile as thumb-2 and use it for my projects. I keep searching online for kernel+thumb2 references and most of them point to this linaro git tree. Regards, -- Markos Chandras / Gentoo Linux Developer / Key ID: B4AFF2C2
