Action Items from this Meeting

  • jcrigby, dmart to follow up on getting linux-tools to build in linaro kernel package
  • slangasek to check on NEW queue status of pdebuild-cross
  • slangasek to escalate bugs 625042 and 620576 to mvo
  • lool to help with a test case for PKG_CONFIG_LIBDIR
  • jcrigby to use for imx51 u-boot testing

Action Items from Previous Meeting

  • slangasek to check with doko regarding landing of last cross-build fixes


  • TBA

Status Reports

Jamie Bennett

This Week


  • Added support for specifying a start and end date when producing burndown charts. This enables per-month reporting which is what is more expected from a traditional project management perspective.
  • Started implementing tagging in the work item tracker.
  • Started implementing the LATER state in the work item tracker. Both this and the tagging support should be finished early next week.

  • Talk with Kate to iron out better bug tracking for Linaro and Ubuntu. Talked over some mock-ups and agreed on a good way to progress.
  • asac managed to get dailies for the vexpress platform building - . Talked with mwaddel to discuss how vexpress would be delivered for beta and onwards and what needs to be done before release.

  • Weekly call with Anmar, notes can be found at JamieBennett/MeetingNotes/2010-08-24. Lots of talk to get ready for next cycle including UDS planning.

  • Call with Mounir to discuss project management in Ubuntu/Linaro.
  • Usual release meeting, notes can be found at Cycles/WeeklyReleaseMeeting/2010-08-26.


  • Work with the Ubuntu Release Manager to implement bug dependency reporting and highlighting.
  • Finish implementing tagging support in the work item tracker to enable work items to be 'tagged' against a technical requirement reference number.
  • Finish implementing the LATER state in the work item tracker.
  • Produce a blueprint and work-item guideline document to ensure that everyone is using the same format for 11.05.

Dave Martin


  • Now in touch with the bootchart upstream maintainers: Ubuntu is not really in sync with upstream, but keybuk is interested in getting back in sync.
  • Still need to summarise code size variation with -Os -- somewhere



  • arm-m-missing-security-features:
    • kees postponed /dev/mem protection to maverick+1, and is working on SECCOMP support; this seems a reasonable compromise.
    • Testing of the security features implemented on armel is now enabled by kees.


  • Investigation of Freescale bsp mostly done -- need to discuss with lool.


  • Summarise -Os results
  • Test the linaro stable kernel tree on OMAP3/Beagle -- see whether the omapfb problems are now fixed.
  • Test omap/vexpress beta release candidates when they've been respun.

John Rigby

Kernel Packaging

  • Delivered a new kernel based on linaro-stable and latest ubuntu.
  • Got feedback from mattman that latest vexpress kernel boots
  • Found and fixed (found fix online for) the omap3 display problem and delivered kernel with that and two other beagle fixes from ubuntu.


  • Did a new merge of latest upstream, latest sakoman omap patches and old vexpress patches.
  • Added multiple deb support to u-boot package build.
  • Delivered u-boot (with much help from slangesek) source package to ubuntu archive.


  • Normal meetings

Next Week

  • Do a new u-boot devtree submission
  • Work on ST-E u-boot

Nicolas Pitre

  • Git repository shuffling on to reflect the better naming agreed between lool, jcrigby and I.
  • Creation of a dedicated Git tree for the Linaro 2.6.35 kernel tree, and its announcement.
  • Review of some partial SECCOMP patches for ARM from Kees/Amit.
  • Review/discussion about proposed approaches to solve the problem of dynamically allocated contiguous memory buffers (hot-plug memory, CMA, etc.)
  • Objective setting for the next annual review cycle.
  • Misc (meeting attendance, mailing list monitoring, etc.)
  • Patch for bug 620611 in launchpad.
