ARM Status

Kernel development: nothing new to report.
Oneiric/ti-omap4: during the last TI call we got to know that _perhaps_ we will get a 3.0 kernel for the O cycle. Still not 100% sure and no ETA yet. Linaro already has a .39 kernel but it doesn’t boot on my panda (while it seems it works ok with a linaro hwpack if device tree is disabled).
Gcc 4.6 and omap usb: lp#791552 has been confirmed as a kernel upstream bug, thus until we get a proper fix and as long as we us gcc 4.6, we loose usb across all the omap* targets. So far all the proposed workarounds didn’t help.

Blueprints: Oneiric Delta Review

apw, lag, manjo, ralveti, rtg: you have work items to review your set of Ubuntu patches which I’ve postponed to Alpha-2 for you. Please take a moment to review when you have a chance. See https://wiki.ubuntu.com/KernelTeam/Specs/KernelOneiricUbuntuDeltaReview for your specific set of patches.

Blueprints: Oneiric Server Requirements

Was able to get some domUs started with Oneiric as dom0. Some strange problem to follow-up on when having xenconsole and console on a serial line. Also need to file a bug to get blkback and netback loaded when the system gets started as dom0. Otherwise there is a strange effect when starting the domUs.

Status: General Oneiric

We uploaded the 3.0-1.2 Ubuntu kernel last week. This was rebased on the upstream v3.0-rc3 release. Alpha-2 is also approaching, ie Thurs June 30. That means we’ll likely upload our final Alpha-2 kernel this Friday June 24th. If there are any patches that need to land in Alpha-2, get them sent to the kernel-team mailing list asap.

Open Discussion or Questions

ogasawara:

  • bjf, the links you post at the start of the meeting still reference Natty, should be Oneiric

    • Noted and fixed.
  • The bug stats we post each meeting, are those useful to anyone other than myself? Would it suffice to just post the link to the stats?
    sconkline:
  • I have the same question about kernel versions in the meeting – is posting th elink just as useful?

    • The elink is more appropriate in that case

20110607 Meeting Agenda

ARM Status

Kernel news/SRU: mainly CVEs for imx51 and omap4, a small config change to avoid a kernel panic on imx51, and another config change to get lxc on omap4. New 4.6 cross toolchain: lp791552 (“No USB support on beagle/beagleXM”) seems it has uncovered a problem with the new 4.6 toolchain, reproduced the issue with a linaro kernel and forwarded to linaro mailing list.

Blueprints: Oneiric Server Requirements

Nothing new.

Status: General Oneiric

We’ve almost resolved all the issues from the v3.0 fallout. We’re just wrestling with module-init-tools to get depmod sorted out. We’ve rebased to v3.0-rc2 and pushed to master-next. With v3.0-rc2, there’s an issue on boot (black screen of death) when the i915 driver is loaded. This can be worked around using i915.modeset=0 at the moment. There’s also reported boot issues on some system’s with atom processors on at least v3.0-rc1. So, I’m a bit hesitant to upload at the moment knowing we’ll break some common hardware use cases.

Module init tools are very very nearly there, last reviews going on now.

Status: Stable Kernel Team

  • Hardy – no bugs needing verification, moving right into QA.
  • Lucid and Maverick – Dealing with USB regressions. New kernels are being packaged and will be uploaded today.
  • Natty – A possible regression was reported, herton is investigating.

Open Discussion or Questions: Raise your hand to be recognized

  • First item is what to do with the Oneiric Bug Handling blueprint

    • The majority of remaining work items center around our bug tooling and are not release critical. IMO we don’t really want/need this to be on the agenda each week. Thoughts?
    • We are going to be doing what we can using tooling and the rest add hock
    • I’ll look over the blueprint and see where i can help out
