ARM Status

Q/master: lp1176977 (“XFS instability on armhf under load”) – passed all xfs
tests (tested both on arm and x86), but there’s still one patch missing (and
waiting to enter linux-next for 3.11).
*/highbank: lp1182637(“cpu_offlining fails to run on ARM”) – indeed, it was a
firmware issue: updating the node to the last available firmware, made cpu
hotplugging work – lp1185669 (“CPU cores offline and can’t be brought back up on
ARM Server card”) is probably a dup.
R/master: lp1171582(“hvc0 getty causes random hangs”), seems like i can detect
the presence of a jtag console (DBGAUTHSTATUS NSNE bit) and thus attach or not
the xen console to it, i’ll give it a try.

Status: Saucy Development Kernel

Our Saucy unstable branch has been rebased to the latest v3.10-rc6
upstream kernel. We unfortunately have still not uploaded yet. We are
still awaiting fixups for a few DKMS packages. We hope to upload by EOW
or early next week. In the mean time we have gone ahead and rebased our
Saucy master branch to the recent v3.9.6 upstream stable kernel and
uploaded.
For our phablet kernels we have been investigating some kernel size
constraints and the modules which we have enabled and built in.
Important upcoming dates:
Thurs June 27 – Alpha 1 (opt in)

ARM Status

Q/master: lp1176977 (“XFS instability on armhf under load”) – turned out some
xfs tests failure that i was experiencing were already present in 3.5.y
vanilla for arm, so none of the backported patches were responsible for it.
On the other hand, there’s a new 100% reproducible hang while running
tests/generic/0368. Still working on it, collecting patches, pinging upstream,
etcetc.
*/highbank: lp1182637(“cpu_offlining fails to run on ARM”) – according to
robherr this is due to a different u-boot that we are using, waiting for an
update.
S/master: did some testing of 3.10-rcX for omap[34], imx6 and vexpress, so
far so good.

Status: Saucy Development Kernel

Our Saucy unstable branch has been rebased to the latest v3.10-rc5
upstream kernel. We are still holding off on a v3.10 based upload due
to missing AUFS support as well as some DKMS package failures we would
like to resolve. We have however gone ahead and rebased our Saucy master
branch to the recent v3.9.5 upstream stable and plan to upload that
today.
On the mobile front I’m hearing news that the container flip should
hopefully be happening this week.
Important upcoming dates:
Thurs June 20 – Alpha 1 (opt in)

    ARM Status

    Q/master: lp1176977 (“XFS instability on armhf under load”) – cherry picked
    more fixes for the preallocation code, rerun the swift benchmark with different
    fs sizes but unfortunately some xfs tests failed, under investigation.
    */highbank: lp1182637(“cpu_offlining fails to run on ARM”) – little progress on
    this one, but i’m still working on it.
    There was a question whether we had helped test the Nexus 7 kernel for phonedations.
    They stated they didn’t have the hw
    That was the only blocker from it landing in the touch images
    Will sync with rtg upon his return then

    Milestone Targeted Work Items

    It appears not all the blueprints are setting the series properly and thus we may be missing some
    work items for our team. I’ll review any oversights and update the table next week.

    Status: Saucy Development Kernel

    Our Saucy unstable branch has been rebased to the latest v3.10-rc4
    upstream kernel. Saucy master-next is currently at v3.9.4. We are
    debugging some boot issues with the v3.10-rc4 rebase, so will hold off
    on uploading a v3.10 based kernel until those are resolved.
    We still anticipate an AppArmor pull request this week from the security
    team to get the latest AppArmor patches into our phablet kernels.
    Important upcoming dates:
    Thurs June 20 – Alpha 1 (opt in)
