ARM Status

  • P/omap4: a new kernel version (1405.7) was released, with improved PM support and fixes for the usb subsystem (CMA revert). P/master: problems with mmc were due to twl4030's GPIO lines being inactive at boot time since support was factored out in a kernel module; recompiling it in the main kernel made omap3 boards boot off the mmc again (12.20). SRU: new kernels were released for every supported arch/release.

Release Metrics and Incoming Bugs

Milestone Targeted Work Items

  • I've pushed out any open work items from Alpha-2 to Beta-1. Additionally, some work items have come to my attention but I'm unaware of anyone from our team actually working on them:


    https://blueprints.launchpad.net/ubuntu/+spec/servercloud-p-ceph [canonical-kernel-team] investigate large xattr support patch from Ted T'so in ext4: TODO [canonical-kernel-team] potentially help push large xattr support to ext4: TODO
    Did anyone attend that session at UDS and commit us to those work items? I suspect these may just get postponed. They were for the cluster filesystem, which is used in openstack. There will be a follow up and see if more details can be found.
    https://blueprints.launchpad.net/ubuntu/+spec/ubuntu-arm-p-optional-initrd [canonical-kernel-team] provide a kernel with uuid support in the internal initrd for measuring
    I vaguely recall there were discussions regarding this work item at the rally, but I'm unaware of what the outcome was?
    The foundations WIs were all postponed/blocked yesterday, including the above work item? A test of with/without initrd can be done, but that wont tell anything about with/with minimal initrd in kernel
    slangasek set his items to blocked.
    ogra_, but don't we have an option to generate a minimal initrd now ?
    ogra can easily provide you with data tomorrow if that helps anyone
    Those would be interesting numbers.
    Minimal means the in-kernel initrd just containing teh blkid command as we had discussed
    Though i think slangasek would even like to see that done in-kernel with a patch (which i think you already said is to intrusive)
    A plan should be discussed for this feature offline, we are clearly confused on who is doing what when in which order
    tgardner: FSVO "minimal" that always includes udev and sundry other utilities
    slangasek, not necessarily, thats why we have devtmpfs, no ?
    slangasek, I guess I was referring to the "tailored" initrd so taht we could see if there was _any_ time differences
    there is no support for generating any genuinely minimal initramfs out of initramfs-tools
    right, it will always be bloated and at least contain both libc's we'll discuss it offline ..
    Everyone OK with moving on?

    Note that the table has a new column this week, the "Defd" column represents the number of CVEs which have been referred back to security for resoution, either for lack of a fix or if the fix is not clearly complete. Nine new CVEs were added this week, of which about 6 have been resolved. We have also finally dropped lucid/mvl-dove from the table above.

Status: Stable, Security, and Bugfix Kernel Updates - Oneiric/Natty/Maverick/Lucid/Hardy
