Meeting Agenda]]


=== 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

 If your name is in the above table, please review your Alpha-1 work
 items.  If anyone has a spare cycle, feel free to take one of the work
 items assigned to the team.
 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:

 Important upcoming dates:
  * Thurs Jun 7 - Alpha 1 (~1 week)

=== Open Discussion or Questions? Raise your hand to be recognized  ===

 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.
