Milestoned Features

  • 16 blueprints (Includes HWE Blueprints)

Bugs with Patches Attached:125 (up 5)

Blueprint: kernel-maverick-apparmor

Submitted next revision to lkml and issued pull request for Maverick, it includes bug fixes for Bug #599450, Bug #581525.

Remaining work items are mostly userspace, and will be sorted out in the next week

Blueprint: kernel-maverick-misc

Nothing new to report.

Blueprint: kernel-maverick-new-kernel-on-lts

Still tracking Maverick. No known issues.

Blueprint: kernel-maverick-pv-ops-ec2-kernel

Pulled in recommend XSAVE patch from Fedora kernels, and we are building kernels that will only work with pv-grub or modified ami's. Kernels are in testing and currently available at:

Have also set up test kernel with pv-on-hvm drivers from amazon compute cloud. There are two versions, the unmodified drivers, and the v6 version that is being pushed upstream. I need to spend more time evaluating each but v6 seems the correct one to use atm.

Blueprint: kernel-maverick-config-review

Only major change is we've enabled CONFIG_M686 per blueprint:foundations-m-686-compile

Blueprint: kernel-maverick-bug-handling

The date for the Triage summit is set. It will be on the 11th of September between 10AM EST and 2PM EST. The classroom will be for the instructional sessions in order to allow leverage of the Lernid tool. We have decided not to use the kernel channel other than for wiki development. I'll be sending an e-mail on Wednesday to the parties we want to have deliver this training.

Blueprint: kernel-maverick-upstart

Testing at the Maverick Rally show threw up a bug in the the readahead tracking patches. This was resolved and we now have a near final patch set. This will be pushed to kernel-team list this week for review.

Blueprint: kernel-maverick-bios-test-automation

Recent changes since last meeting:

  • automate fwts ISO build (for USB keys)
  • check msr registers for nx bit, check nx bit across all CPUs
  • fix typos in man page
  • --batch-experimental, --interactive-experimental options
  • --show-tests reports tests based on --interactive, --batch flags
  • virt: more understandable results output
  • mcfg: improved test failure explanation
  • battery: more thorough, make test interactive
  • s3: add variable delay between each S3 iteration
  • investigate 2TB BIOS disk limits

Status: Maverick

The Maverick kernel saw some significant changes last week while at the Platform Rally:

  • We updated to CONFIG_M686 per the foundations-m-686-compile blueprint.
  • The toolchain saw a last minute update which introduced a serious issue where i386 kernels would no longer boot. Luckily an upstream patch to resolve the issue has been isolated and applied.
  • We rebased the Maverick kernel to the latest 2.6.35-rc6 mainline kernel and uploaded, ie 2.6.35-12.17.

Considering all the changes, please be sure to help test. Alpha 3 is Thurs Aug 5th which is ~1week away. Any patches that are to land in the Alpha3 kernel need to be submitted and garnered the appropriate Ack's *before* this Friday (Jul 30). For those that have already sent patches, I'll be applying them today. Also, please note we are significantly above the Alpha 3 burn down chart's trend line. Review your list of work items for Alpha 3 and start closing out tasks asap. If your work items won't be completed by the milestone, re-target it or mark it POSTPONED.

Security & bugfix kernels - Karmic/Jaunty/Intrepid/Hardy/Others

  • Upd./Sec.




    Dapper: Kernel


    Hardy: Kernel


    Jaunty: Kernel


    Karmic: Kernel


    = mvl-dove


    = fsl-imx51


    = ec2


    Lucid: Kernel


    = LBM


    = mvl-dove


    = fsl-imx51


    = ti-omap


    = ec2


All proposed packages have moved to updates. Awaiting security release anytime soon. Since there has been some weird testing problems on Lucid fsl-imx51 we will hold back that kernel however all other kernels are being uploaded.

Incoming Bugs: Bug day report

I decided toward the end of last week to postpone the weekly bug day to next week. We will be reviewing new bugs that have been erroneously set to new after information has been provided. We will also urge additional commenters to open new bugs for their issues and remove duplicates as we see them. The Kernel Team Bug day will once again be on half a day Friday and half a day Monday. please do what you can on our top50 list.

Open Discussion or Questions:

  • Just a heads up that usb-creator on lucid cannot make bootable images of maverick (see bug #608382 for a work-around)
