Linaro Kernel Consolidation WG Weekly meeting (2010-8-5)

by Matt Waddel

The complete weekly report for the Linaro Kernel Consolidation team may be found at: https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Meetings/2010-08-… Summary of the minutes: Device tree support - ARM specific patches in Grant's test tree - probably will be included in the 2.6.38 kernel release - Patches making good progress, just takes time Richard discussed device trees at the TI OMAP open source meeting. - Most maintainers were receptive and would like to see patches merged. - Russell King had reservations. Concern was the lack of standardization within the ARM community could cause messy implementations. Device tree support for OMAP. Jeremy could use some hardware to speed testing. Arnd asked about QEMU support for the Versatile Express. - Needs to be added to a specification for this platform and scheduled. - Richard pointed out there there was a QEMU branch(qemu-maemo) with OMAP support, but the necessary PCI support wasn't implemented. - Device trees may help in situations like this. Versatile Express device tree support is coming. Arnd reviewing ST Ericsson, out of town next week - Waiting for the BSP, but has hardware Boot architecture WG - Grant to kick-off this team after the kernel merge window No alpha3 testing done within the group Please let me know if you have any questions. --Matt

So I guess, native compilation is the only way out now, until this problem is solved? http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=591522

problem with xdeb

by Dechesne, Nicolas

hello, i am trying to cross compile our packages using xdeb. I am following the steps from the wiki (e.g. I am using a maverick chroot where I install xdeb and cross compiler). I can cross compile the 'grep' example fine. However when I try to cross compile our packages, it seems that xdeb is not able to handle the dependencies well. I am building new packages, e.g. that do not exist in maverick archive, instead they are stored on a private archive within the company. I have the following packages titiler-memmgr, tisyslink-lib and tisyslink-d2cmap. I cannot share all sources for now, but here is the package information for these 3 (extracted from the archive Sources file) Format: 1.0 Package: titiler-memmgr Binary: titiler-memmgr, titiler-memmgr-dev, titiler-memmgr-tests Architecture: armel Version: 0.24.8-0ubuntu1 Standards-Version: 3.9.0 Build-Depends: cdbs, debhelper (>= 7), quilt, libtool Format: 1.0 Package: tisyslink-lib Binary: tisyslink-lib, tisyslink-lib-dev, tisyslink-lib-tests Architecture: armel Version: 0.24.8.1-0ubuntu2 Standards-Version: 3.9.0 Build-Depends: cdbs, debhelper (>= 7), libtool, titiler-memmgr-dev (>= 0.24.8) Format: 1.0 Package: tisyslink-d2cmap Binary: tisyslink-d2cmap, tisyslink-d2cmap-dev, tisyslink-d2cmap-tests Architecture: armel Version: 0.24.8.1-0ubuntu1 Standards-Version: 3.9.0 Build-Depends: cdbs, debhelper (>= 7), libtool, titiler-memmgr-dev (>= 0.24.7), tisyslink-lib-dev (>= 0.24.7) So, now I am using xdeb with --sequence, here is the output: $ xdeb -a armel --apt-source --sequence titiler-memmgr Build sequence: titiler-memmgr $ xdeb -a armel --apt-source --sequence tisyslink-lib Build sequence: tisyslink-lib* $ xdeb -a armel --apt-source --sequence tisyslink-d2cmap Build sequence: tisyslink-lib* tisyslink-d2cmap* What is quite disturbing is that xdeb is able to figure out that tisyslink-d2cmap depends on tisyslink-lib, but it does not get that tisyslink-lib depends on titiler-memmgr. As such the build fails. Can something be wrong with my packages? How does xdeb figure out dependencies? I would expect that it would use the Build-Depends from the control file, but I am not sure. Let me know if you need additional data to debug further. cheers, nicolas

Re: [PATCH 0/2] Make PowerTOP generic

Hence for cross compilation we need to make sure that this (or a non-wide char ncurses library, i.e. libncurses) should also be cross compiled for target ARM. And then we should have some option in Makefile (LIBPATH & INCPATH) to point to it. Will it make sense to have a "readme.ARM" or some other file in powertop which describes this step ? Any suggestions on how best to do this ? Thanks! -- Regards, Amit Arora > Vishwa

Alpha-3 approaching, please test

by Jamie Bennett

Hi all, We are fast approaching Linaro Alpha-3 [1], the archive is frozen [2], and now is the time for testing. Can anyone with a supported board please download the daily image (which will turn into Alpha-3 on Thursday) and test. With your help we can make Alpha-3 rock even more. For full instructions on how to test and the progress made this cycle, please see https://wiki.linaro.org/Releases/1011/Alpha3 Regards, Jamie. -- Linaro Release Manager [1] https://wiki.linaro.org/Releases/1011#Linaro10.11Schedule [2] http://lists.linaro.org/pipermail/linaro-announce/2010-August/000007.html

perf userspace tools fixes for Ubuntu / linaro

by Dave Martin

Hi there, I worked on a few patches to the help the userspace perf tools do better at loading debug symbols -- this is particularly of interest on Ubuntu and Linaro where separated debug symbols in .ddebs are typically not loaded even when present. Note that even with the patches, the contents of .ddebs are still not cached by perf along with the other profiled binaries, so you will still lose the symbols if you uninstall/upgrade your ddebs in the meantime. This should get fixed in the future. Due to mailserver issues, Arnaldo kindly helped merge these patches for me. The patches are now merged to the linux-2.6-tip master branch. You can find details of the commits here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/608775 [ Nico: WIll says he's going to pull these patches into his linaro branch, if it's more convenient for you to pull from there. ] Covering notes explaining the changes follow. Cheers ---Dave >From c1cb454cc818d367e6b679600bbe7c2fc6d75c2c Mon Sep 17 00:00:00 2001 From: Dave Martin <dave.martin(a)linaro.org> Date: Tue, 27 Jul 2010 16:44:36 +0100 Subject: [PATCH 0/2] tools/perf: Fix debug symbol lookup issues for some OSes On Ubuntu (and some other OSes) debug symbols for most of the binaries are split out into separately-installable files under /usr/lib/debug or elsewhere. perf already supports this setup, but as a side-effect of abbreviating the prefix of paths beneath the current directory to './' for display purposes, the paths constructed to search for the separate debug images are incorrect. As a result, symbols may not be found even if they are available. The simplest fix seems to be just to remove the cwd abbreviation feature; this makes all displayed paths absolute in e.g., perf report -v, but otherwise appears harmless.

This patch set modifies the image search behaviour to perform 2 passes: no image without a full symtab is considered for loading unless no image with a symtab is available at all. This avoids loading images from the buildid cache if a better image is available elsewhere. As a consequence, perf report and friends should now load the correct symbols on Ubuntu and friends, at the cost of an extra image loading pass. This patch set does not change the way files get cached, but ought to be OK as the basis for further refactoring to replicate the same search behaviour in the caching code so all relevant images get cached. The extra image loading pass should not need to occur on the common path once the caching behaviour modifications are done.

Main archive frozen for Alpha 3

by Jamie Bennett

Hi, Hot on the heals of Ubuntu's main archive frozen announcement [1] this email is to inform you that Linaro development is under the same restriction. We are in the process of testing the daily images which will in turn become the Alpha-3 release on Thursday. Please read the Ubuntu announcement for more information on the restrictions. Regards, Jamie. -- Linaro Release Manager [1] https://lists.ubuntu.com/archives/ubuntu-devel-announce/2010-August/000741.…
