ARM Status

Q/omap4: Ubuntu-3.4.0-201.3 is out, with hdmi and jack audio support. Some of the new features (like video and audio offloading to gpu/dsp) will have to wait until 3.5rcX hits master, since we need CMA and dma-map support (already present in linus vanilla).
only fools rush in

Last week we uploaded the 3.4.0-3.8 Quantal kernel. This included an
updated AppArmor patch set and misc config updates and bug fixes.
Please note that Alpha-1 is next Thurs June 7. I’ll intend to upload a
final Alpha-1 kernel early next week, ie Monday.
We’ve also began providing the 12.10 kernel for 12.04. We welcome any
early adopters to plaes install, test, and let us know your feedback.
It is available from the following PPA:

kamal, go ahead
An old colleague of mine, Dave Taht, is a member of the http://www.bufferbloat.net/ group. Some of their work will be landing in the 3.5 kernel (codel and fq_codel – a new active TCP queue management algo).
Dave would like to be in contact with someone on the Ubuntu kernel team to talk about configuration and usage issues for that stuff. Shall I direct him to anyone in particular? Is there a networking point-person?
kamal, i’d say just get him to send email to kernel-team@
kamal, he can start with me or apw
kernel-team@ works as well
ok, two names + the kernel-team@ list :-) that’ll do :-) thanks.

ARM Status

Q/omap4: first omap4 kernel (Ubuntu-3.4.0-200.1) based off 3.4rc7 has been pushed to the repository – some noticeable bits were disabled (omap5 support, sound, sata, dsp, etcetc) but work is geared to enable all the remaining parts.
A v3.4 based version was uploaded.

Status: Quantal Development Kernel

We’ve rebased the Quantal kernel to upstream v3.4 final and uploaded.
This upload collapses the -virtual flavor, reinstates the i386 generic
flavor, and transitions the i386 generic-pae flavor to the generic
flavor. We’ve also homogenized the entire linux-meta package and
removed the non-smp powerpc meta package as it was made obsolete in
Precise.
Important upcoming dates:

  • Thurs Jun 7 – Alpha 1 (~2 weeks)

a few things…
Work items are beginning to populate the blueprints. I’ll start calling
out specific work items in upcoming meetings.
We’ve rebased the Quantal kernel to upstream v3.4-rc7. We uploaded but
ran into a build failure on i386. Test builds are currently underway
and we will re-upload shortly. We also have the quantal kernel building
in precise. We are getting a PPA set up so that testing can commence.
Important upcoming dates:

  • Thurs Jun 7 – Alpha 1 (~3 weeks)
