Greetings,
If someone has something which is not in the mainline, was not in the
12.01 kernel release, but worth including into the 12.02 kernel release,
please let me know by the end of Feb 14, PST (the git branch where I
could pull from). This release will be v3.3-rc3 based, so you patches
should be based on that (easiest for me), or on the tip of the linus tree.
My expectations are that the power management WG has some topics to add
to the 12.02.
I am aware of git://git.secretlab.ca/git/linux-2.6.git, irqdomain/next
The kernel working group has some blueprints for 12.02. Please let me
know, if there is something for me to do here.
The following commits from linux-linaro-3.2 branch will be carried over
to 12.02:

1.7.9.1
Hi.
I'm currently fumbling around in the dark, trying to find a kernel which
I can use to compile the powervr drivers, as well as with rpmsg support.
Ideally the rpmsg should already be in the kernel, but I can see that
this might be hard, and cherry picking is an ok solution. I'm wondering
if one of the ti landing team kernels might be suitable for this, and if
one of these is considered a stable kernel?
Last kernel I looked at was the LEB 3.1.5+ kernel,
release-linux-2011-12, which worked fine for compiling the pvr drivers
from rsalveti, but didn't contain rpmsg drivers. When I tried the
release-linux-2012-01 kernel, 3.2.0+, it could compile the powervr
driver, but didn't contain the rpmsg drivers and didn't actually run, as
I got the message 'coherent pool not initialized' from the kernel when
trying to allocate for the ehci-omap.
The kernel will be run on a device with an omap4460 if this is of interest.
I would really appreciate your help on this, as I feel quite lost in all
the different branches and tags which reside in the different linaro
kernels, so a repo with a stable commit would really help. As most rpmsg
implementations I have seen follows the 3.2 kernel, that would really be
preferable if I need to cherry pick, but if not I don't really care if
it's 3.1 or 3.2.
If you have any questions, please do not hesitate to ask them.
Best regard
Martin Ertsas
Hello,
Continuing on the ARM Porting effort to fix the remaining issues with
Precise, we'll be having the ARM Porting Jam this friday as well!
The main focus for this Friday, besides the usual FTBFS issues
described at http://people.linaro.org/~rsalveti/arm-porting-queue/arm-porting-queue-repo…,
is porting the most packages we can to be multi-arch compatible. This
will allow us to increase the list of packages we can easily
cross-compile using multi-arch.
Wookey got a quite long list of things to do at
https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/MultiarchCrossBui…,
so please have a look and make sure to get in touch with him at
#linaro @ freenode if you need any extra help.
Happy porting!

Hi there,
Launchpad now supports blueprint work items natively and we've already
migrated the work items from the whiteboards of most Linaro Blueprints.
Most of us wouldn't even notice those changes because we still have a
text field to enter work items and it uses the exact same format we used
before. In the future we might improve the user experience but for now
we decided to keep the same UI and format. There's a blog post with more
information, if you're curious:
http://blog.launchpad.net/
In practice this just means you'll enter the work items in the 'Work
items' field instead of the whiteboard (the meta info
[acceptance/headline] still go there, though), but the work items of
some of our Blueprints could not be migrated, so I've spammed^W sent an
email to the owner/assignee of each of them. It would be nice if those
of you who receive that email migrated your BPs manually but even if you
don't status.l.o is setup to pull work items from both the new field and
the whiteboard, so you'll still see your work items there.
And if you're curious why we're doing all this, it's so that we can
implement the monthly engineering views in Launchpad:
https://dev.launchpad.net/Projects/WorkItems
Cheers,

The common clock framework defines a common struct clk as well as an
implementation of the clk api that unifies clock operations on various
platforms and devices.
The net result is consolidation of many different struct clk definitions
and platform-specific clock framework implementations.
Thanks to Sascha Hauer and Andrew Lunn for their great review and
feedback on the previous v5 series.
Major changes since v5:
* removed redundant HAVE_CLK_PREPARE in Kconfig
* new CONFIG_COMMON_CLK_DISABLE_UNUSED feature
* results in a new clk_op callback, .is_enabled
* standardized the hw-specific locking in the basic clock types
* export the individual ops for each basic clock type
* improve registration for single-parent basic clocks (thanks Sascha)
* fixed bugs in gate clock's static initializers (thanks Andrew)
* overall improvements to Documentation/clk.txt
* rebased onto Linus' v3.3-rc6 tag
Major changes since v4:
* rolled in TGLX's comments on overall design. We now have,
* proper handling of root clocks and orphan clocks
* multi-parent clocks are handled in the core
* struct clk is shielded from struct clk_foo and vice versa
* this is a return to the previous struct clk_hw design
* split basic clock types out into separate files
* split headers up by purpose
* clk.h remains the driver-level interface
* declarations for rate change notifiers are the only additions
* clk-provider.h is primary header for implementing clock operations
* clk-private.h allows for static initialization of clock data
* validation and bug fixes
* rebased onto Linus' v3.3-rc5 tag
Patches can be pulled from:
git://git.linaro.org/people/mturquette/linux.git v3.3-rc6-clkv6
v5 can be found at,

1.7.5.4
For the 12.01 cycle the Linaro Platforms team is pleased to announce
the availability of the new linarotv-xbmc based image. This combines
the xbmc media server project with linaro's leb to result in a "works
out of the box" arm based media server image.
It can be found at http://snapshots.linaro.org/oneiric/linaro-o-linarotv-xbmc/
Currently the best experience can be found on Panda/Panda ES however
boards with hardware video acceleration enabled should work well. We
welcome feedback and suggestions on the image. Support is on a as
"best can" basis. Bugs if found should be written against
linaro-ubuntu in lauchpad.
Enjoy!
