20110531 Meeting Agenda

ARM Status

Kernel news/SRU: nothing exciting – a small fix to support beagle xm rev c, some work for lxc support in omap4, while a boatload of CVEs fix for imx51/mvl-dove/ti-omap4 is approaching.

About the O cycle: TI told us they are going to spend a lot of resources/efforts to make 2.6.39 tightly/well integrated with their BSP AKA we get 2.6.39 in oneiric/ti-omap4. No ETA yet, but same path as before TI -> Linaro LT -) Ubuntu.

Unsupported news: davidm is pushing Toshiba ac100 (tegra2) around, and ogra has packaged a kernel for it – guess we are going to experimentally support tegra in the not-so-distant future.

Blueprints: Oneiric Server Requirements

  • None of those started so far
  • Though 3.0 has the last part for Xen

Status: General Oneiric

Over the weekend we uploaded the 2.6.39-3.10 kernel which is based on upstream v2.6.39 final. I intend to keep us on v2.6.39 final for our Alpha-1 release on Thurs June 2. Even bigger news for those who haven’t heard is that Linus released v3.0-rc1! This does introduce a bit of an issue for our scripts, but we’re actively working to deal with the fallout and get our versioning in shape. This also means we’ll target Oneiric to release with a v3.0 kernel rather than v2.6.40.

Status: Stable Kernel Team

We are beginning preparation for another kernel release cycle, but were delayed by problems discovered when running generic kernels in xen dom0 in Lucid and Maverick, and by a potential USB 3.0 problem in Natty. Despite a request to not publish the known-bad Lucid amd Maverickkernels, Lucid kernels were published and are currently in the field. It was only discovered this morning that the kernels
had been published, due to the three day weekend in the U.S. and it appears to have been due to miscommunication.

The next update for Lucid kernels should fix this problem, but these kernels (which had been prepared) must now be respun because the one in proposed was released. The previous kernel cycle is still incomplete due to problems verifying whether an issue seen on Natty USB3.0 really exists.

Today the stable kernel team will remove all three USB 3.0 patches which were applied during the last cycle to Natty, and begin th enext cycle. If we can get a response from the original reporter of the issue, we will attempt to determine which change caused his problem, if any.

On a more positive note, Support for Dapper expires tomorrow.

Blueprints: Oneiric Bug Handling

All alpha 1 items are in progress:

  • [jeremyfoshee] work with SRU team and KRM to develop/define process for addressing development kernel bugs.: INPROGRESS

    • started this conversation with an e-mail.
  • [jeremyfoshee] Generate specific hotlist for devel bugs focus: INPROGRESS

    • will initially use the same requirements as the ‘by team’ hotlist, but focused on Oneiric
    • copied the hotlist script and currently working through changes
  • [jeremyfoshee] drive new state bugs to 0 and maintain 0 new status bugs daily: INPROGRESS

    • 8 current oneiric bugs. All have been initially triaged and are now going through deeper analysis so far this has helped me determine what skills I’d like to further develop
  • [jeremyfoshee] identify which scripts we no longer run which we should port forward (with the aim of 0 New bugs): INPROGRESS

    • Brad’s confirmed script is doing a great job currently of identifying what bugs are complete enough to be set confirmed
    • Started the discussion on this in e-mail. Will follow up with some thoughts as soon as I have had the time to evaluate the responses and chatted with Pete (he’s been quite busy lately :))

Blueprints: Oneiric Config Review

We just need to schedule a follow on config review session to look at jj’s config comparisons. I suggest we do this at the Rally. I’m continuing to work through some of the config options noted from UDS, none of which are critical for the Alpha-1 release.

Blueprints: Oneiric Delta Review

apw, bjf, jjohansen, kees, lag, manjo, mpoirier, ralveti, rtg: you have Alpha-1 work items to review your set of Ubuntu patches. Please take a moment to review or postpone till Alpha-2. See https://wiki.ubuntu.com/KernelTeam/Specs/KernelOneiricUbuntuDeltaReview for your specific set of patches.

Blueprints: Oneiric Server Requirements

All good (nothing started)

Status: General Oneiric

We’ve uploaded the 2.6.39-3.9 kernel which is based on upstream v2.6.39 final. I intend to keep us on v2.6.39 final for our Alpha-1 release on Thurs June 2.

Status: Stable Kernel Team

All kernel packages in -proposed have had verification complete and will be published when Certification and
QA are complete (Not all series receive Certification). The Stable team will prepare new kernel packages this
week to begin a new cycle.

As decided at UDS, the stable kernel cadence will change to a three week cycle, in order to allow time to
properly prepare the kernel packages

Herton is part of the stable team this cycle and Brad is part-time while doing work with QA.
