Status Reports

Jamie Bennett (JamieBennett)

This Week

  • Lots of bug tracking and prodding people nicely to get bugs fixes done before Final Freeze.

  • Produced a "How we plan a cycle" presentation. Will be circulated to hopefully answer some questions on a high level about the release cycle and planning.

Hardware Enablement
  • Liaising with ARM on Versatile Express issues. Matt is filing bug reports and we are getting good reports and investigations from the ARM VExpress team.
  • Hardware pack discussions.

  • Pushed a small change to the work item tracker, some discussion about some of my changes.
  • Seed issues and investigations. Pushed some fixes but overall some heads still don't build. Waiting on Hardware Packs before further investigations.

  • UDS planning meetings.
  • Talked with mwaddel to discuss VExpress, Anmar a few times to sync, weekly foundations meeting, Linaro release meeting and Ubuntu release meeting.
  • Twice monthly call with ARM to discuss Linaro: Notes.

  • Booked travel for sprint next Jan.


  • Lots of bug triage and blueprint tracking.

armel-cross-toolchain took whole time - it builds fine, results are available in my PPA, old repository is now deprecated. Since wednesday I did lot of cleanups and improvements.

At the end of day I released 1.34 and 1.46 versions - they will be uploaded to PPA on Monday (after gcc-4.5 release). That's because mangling of versions got removed and ppa contains mangled gcc-4.5 packages.

Some extra patches got merged into gcc packaging - cleanups and fixes. Mostly cosmetic but my packages were broken without them.

Also started wiki page to collect all data needed for applying for Ubuntu developer membership - address was given to Luic on #linaro if you want to look.



  • Wrote and Gave Debconf10 talk at Doughnut session. Went well.
  • Went to Opentech in London - lots of really good stuff
  • Cross-toolchains became available in a PPA last week - (need to update multistrap default config accordingly)
  • Wrote simple-minded autobuilder to try building all of linaro-alip with xdeb and bdebuild-cross. Found bugs in pdebuild-cross and apt. Looking for build-failure patterns.
  • PKG_CONFIG_LIBDIR fix tested, upldated on feedback and now upstreamed. Waiting for an official upload.
  • Tried to reproduce but found another problem instead. apt package/suite syntax not working. Still characterising.


  • Apt bugs preventing multistrap/pdebuild cross form 'just working'
  • Still crap at python


  • Run simple-minded autobuilder
  • file cross-build bugs accordingly - especially looking for patterns
  • Work on xdeb target-arch downloading
  • Update Multistrap to fix bugs, use new PPA
  • Couple of meetings:
    • Cambridge Wireless location Sig, Tuesday afternoon
    • Balloonboard 4 planning meeting Thursday afternoon.
  • Update wiki with more cross-building info and current state of play

John Rigby

Kernel Packaging

  • Completed the first monthly kernel release
  • Uploaded the ST-E kernel to PPA


  • Started on new stable based on v2010.09
  • Asked Jeremy Kerr about testing devtree on mx51, he said there is not anything uptodate right now.


  • Off Monday for Labor Day
  • Normal meetings

Next Week

  • First monthly U-Boot release is due Wednesday, which will be a good time to rebase on v2010.09.
  • Will try to get u-boot devtree stuff tested with hacked beagle kernel from Grant Likely.

Nicolas Pitre

  • Monday September 7th was a holiday (labor day)
  • Started making clear separation between ATAGs and DT support in the ARM boot code. This should make the addition of DT patches on top more enjoyable.
  • Investigation of a new approach for solving LP bug #620611. A new patch should result from this which should be acceptable for mainline.
  • Moved more patches from upstream to the linaro 2.6.35 stable tree to fix some issues.
  • Tracked a silly 64-bit related issue in the upstream BRLTTY repository that prevented the latest version from running on my system.
  • Misc (meeting attendance, mailing list monitoring, etc.)
