ARM Status

Q/omap4: nothing new this week – for alpha2 we are going to use alpha1 kernel, but after we cut this milestone, work on a 3.5 “almost vanilla” kernel will immediately start.
Q/omap3: 3.5rcX came with regressions in different subsets (video, mmc and usb) – a pending kernel (3.5.2-2) should have fixed all these issues.

Status: Quantal Development Kernel

We have recently rebased the Quantal kernel to the latest v3.5-rc4
upstream kernel and have also uploaded. We hope for this to land in the
Alpha 2 images. This also contains some critical bug fixes for omap3 and
i386 cloud images. It’s currently building in the quantal-proposed
pocket. This will also get uploaded to the q-lts-backport [1] PPA to
help facilitate testing of the 12.10 kernel in 12.04. We welcome any
early adopters to please install, test, and let us know your feedback.

Open Discussion or Questions? Raise your hand to be recognized

kamal:
I’ve recently been working with the upstream Bufferbloat group: http://www.bufferbloat.net …
They have implemented new network scheduler algorithms designed to address the performance drag induced by large unmanaged network buffers. The new stuff (“fq_codel” and “codel”) just landed in linux 3.5.
A good article about the bufferbloat problem and the new scheduling algo’s is here: http://queue.acm.org/detail.cfm?id=2209336
The result is *very* impressive: I see a 30X reduction in ping latency on a fully saturated 10Mbps network, just by switching on the new fq_codel scheduler.
For an interactive ssh session over that same saturated 10Mbps network, fq_codel totally eliminates the laggy keyboard response — it feels like there’s no other network traffic at all!
I have produced a Bufferbloat PPA to allow us to experiment with this stuff now in Precise and Quantal:

https://launchpad.net/~kamalmostafa/+archive/bufferbloat

The PPA includes a “quantal-3.4-plus-bufferbloat” kernel for precise and quantal. (The new schedulers won’t work on pre-3.3 kernels). The PPA page links to a quick how-to-smoke-test-it guide and more info.
The Bufferbloat group is eager for testing and feedback and general eyeball time from the Ubuntu kernel team and the Ubuntu community. Their channel is #bufferbloat on freenode.
Please give my PPA a whirl, and get a taste of the new cutting-edge network goodness. Any questions about it — I’ll at least know who to direct you to, so feel free to ask me.

BenC:
I had this on the meeting agenda, but don’t see it above.
Trying to get some feedback for the patches I sent to kernel-team@, hoping to get it merged for next kernel upload
Re: PowerPC e500mc
BenC, i think that are being reviewed at the moment arn’t they ?
If so, I’m unaware
Also, if there are any suggestions on changes to my workflow for getting powerpc stuff merged, let me know
we are looking at them and seeing if they scare us or not
bjf: The only scary one(s) are the mdio phy changes, but I have tested them extensively on non-ppc
BenC: just got back after 5 days off. they are on my todo list.
Everything else is either nop or segmented on non-ppc
tgardner: thanks
a lot of the patches are sauce, are those also heading upstream ?
All of them have been pushed upstream
2 have been accepted
BenC: I should have some comments by tomorrow. got a huge pile of email to deal with…
Oh wait, not the SAUCE, not yet
freescale had 360+ patches last year, so they’ve done a lot to get this merged upstream
These are the last few, and are being dealt with in the coming months
tgardner: ok, please email, ping me if any questions come up…
will do
Anything else for open discussion?
Thanks everyone
