    toolchain patches to land in the archive this week



    works, but needs cleanup; working on final patch


    npitre, jcrigby

    tentative stable linaro kernel tree published, Versatile Express packages coming



    modified bootchart to record memory usage info. TSC just approved license.



    ASLR to be done next week, requesting FFe





    u-boot packages in ppa



    xdeb needs work to support downloading Packages files for the correct architecture and to use these for calculating dependencies; in progress



    preliminary library packages in ppa, but need to talk to LSB about standardizing paths

Status Reports

Dave Martin

Memory Footprint

  • Extended bootchart to collect global memory usage status - should be uncontraversial since the amount of extra data is modest compared with what is already collected.
  • Extended pybootchartgui to graph overall memory usage in a simple way - needs tidying up and discussing the the package maintainers
  • Stalled on TSC licence approval before code can be pushed to launchpad - confirmation expected today.

Perf tools


  • Discuss with plars how to extract useful summary information from the memory usage info, for integrating into the automated testing infrastructure.

  • arm-m-ael-alip-evaluation:
    • Now have a bootstrapped (but unpackaged) v7-a thumb2 compiler, patched to successfully build ncurses with xdeb
    • Building armv5/v6 etc compilers should now be trivial.
  • arm-m-ael-alip-appman-ext:
    • File sytem sizes shown in both command line & GUI runs


  • Bootstrapped compiler fails in xorg-common/mesa
  • Broken packages in buildds


  • arm-m-ael-alip-evaluation:
    • Continue work item "Build cross-compiler binaries from maverick compiler source packages for architectures armv5 & armv6"

  • Found some issues with flash-kernel and pushed fixes.


  • Did some more cleanup recommended by Tim G.
  • Incorporated additional changes from Tim G.


  • Submitted device tree patches to u-boot mailing list for review.
  • Started working on fixes based on comments.
  • Created a linaro u-boot branch on that is based on
    • current upstream
    • rebased C4/xM patches
    • Versatile Express patches from Matt Waddel
    • Debian packaging It currently builds u-boot binaries for panda, beagle, babbage and Versatile Express

Next Week

  • Go back to kernel packaging and add versatile express building.
  • Decide if/how to do separate kernel source packages.
