Kernel Team Meeting Minutes « Canonical Kernel Team

In collaboration with the community team, it was thought that bugs with patches attached would be a good target for issues which we could likely fix quickly and therefore close. It was requested we add this info to our weekly meeting.

Blueprints: kernel-lucid-bug-handling

ogasawara is passing some action items to JFo as part of his becoming the kernel team qa person.

Blueprints: kernel-lucid-review-of-ubuntu-delta

We have added the new DEVTMPFS device to the ubuntu delta for Lucid 2.6.31 based kernels.

Blueprints: kerne-lucid-kernel-config-review

Review of built-in sub-systems planned for the distro sprint.

Blueprints: kernel-lucid-kms

Nouveau from 2.6.33-rc4 pulled into LBM and LBM generally prepared for Lucid. Currently available from my (apw) PPA for testing. Seems you need to manually installl -nouveau X-server components to get this working. X team is going to do some testing before the distro sprint, with a view to making a decision on Nouveau support and how to deliver it there.

Blueprints: kernel-lucid-suspend-resume

Nothing new to report there

Blueprints: kernel-lucid-apparmor-development

dfa optimization is done. There is a bug in table compression improvements so I (jjohansen) backed that out for the moment. I (jjohansen) am aware of 3 regressions in current upstream code base and am looking into them. They are minor regressions in corner cases but 2 of them may be coming from LSM tweaks.

Blueprints: kernel-lucid-boot-performance

The regression in filesystem mount time remains, that is planned for discussion at the Platform sprint. We had regressions caused by the late battery update changes (which gave us .3s during boot). A revised patch moving the update async appears to resolve the issue and retain the gains.

Other Release Tasks: Lucid Audio Support

Nothing major to report. The alsa c-o-d is busted right now and I’m working to get it fixed.

Other Release Tasks: Lucid Better Power Mgt

Nothing new to report here.

Other Release Tasks: EC2 Lucid Kernel Status

EC2 patch update is slow, going. I have had 1 kernel off of slightly older patchset not boot. I have rebased and pulled in the latest patches from today, and redoing. I am dropping all the conflicts in drivers that I can.

Status: Lucid

The main kernel is now pulled up to 2.6.32.6 pulled in and ready to upload. ARM Marvell Dove just updated to 2.6.32 and so we should expect some breakage there. ARM Freescale IMX51 is now on the Freescale BSP and we receieved some 30 additional patches which are applied; upload is pending security updates on the main tree. We have a lot of work outstanding still for Lucid. With only 19 of 57 tasks closed or deferred. We need to review our alpha-3 deliverables and concentrate on those.

Security still getting finalized. We are including all the topic branches into the update this time. So this adds to the effort. Karmic-proposed needs to be updated before uploading as there has been one regression detected in the 2.6.31.9 update.
