Enclosed please find the link to the Weekly Status report
for the Power Management working group for the week ending 2011-09-16.
== Weekly Status Report ==
https://wiki.linaro.org/WorkingGroups/PowerManagement/Status/2011-09-15
== Summary ==
* The PMWG will handle the common struck clk work, going forward
* Steve Jahnke gave thermal talk at Linux Plumbers Conference which was
pretty well received. Got a lot of comments and feedback from not just
upstream, but also other Si vendors (Intel, Nvidia, Qualcomm).
* Basic feedback was that existing framework SHOULD be able to handle
what we need (governor structure, etc.) so we should submit patches to that
first.
* The more complex items (tying multiple sensors into a single thermal
zone) would be welcomed additions so we should propose and take the lead
here
* Samsung: Hosted the thermal sensor driver, thermal governor , cooling
devices and the DVFS fixes that are not in mainline
* Started testing sched_mc features in samsung exynos board.
* Continuing the work on imx cpuidle driver, modifying code to be more
community friendly and testing and fixing issues for compatibility with
i.MX6Q.
* Initial tests on the cpuidle menu governor showed some significant
power inefficiency for some contexts, will discuss the findings with Linaro
PMWG.
* Studying the impact of flags and fields of struct sched_domain in
scheduling policy
Best regards,
Mounir

The disks are plugged in and ready for provisioning.
* PM/TL to re-discuss weekly testing and comes out with a plan. - TODO
* pfefferz/mansson/dzin to sort out the PoC for Android. might need some
redefinition of who we need. - DONE
Android Team has provided their point of contacts.
* fabo to drop all patched repo instance from the release websites. - DONE
Zach would like to mention repo in the lessons learned for Linaro 11.09
post-mortem.
== Agenda ==
* The blueprints have a headline and an acceptance criteria - INPROGRESS
See http://wiki.linaro.org/Cycles/1109/Release/Blueprints
* Release response team
The release response team setup is completed. We have a good coverage of
supported boards. For more information, see:
http://wiki.linaro.org/Cycles/1109/Release/PointOfContacts
* Android/Ubuntu kernel process
The Android Team have 6 different processes for handling kernels. These
differences slow them down. dzin/mansson have been asked to drive the effort
to unify how kernels and other code get delivered and managed for
Android/Dev Platform. Zach should write something on how the components get
delivered. He has a list of requirements already. The output will land on
the Release process.

Hello,
We're running Jenkins EC2 plugin v 1.11 on android-build.linaro.org,
which is 2 releases behind the latest 1.13. Per ChangeLog, it fixes
slave label expression evaluation, which affected me once when I tried
to do more flexible slave selection for builds (we fortunately were
able to get past it by the fact that we use same 64-bit slave type for
both platform and toolchain builds).
So, I'd like to schedule an upgrade some time next week, to allow for
sandbox testing and feedback collection time.

Since we have had over 300 views of NEON optimization on ask.linaro.org, it
looks like there is enough interest in continuing the NEON Forum face2face
meetings at LC Orlando.
I am collecting topics for discussion and wanted to extend an invite to the
broader team, to see if anyone wanted to present a short topic. It doesn't
have to be an elaborate presentation, maybe just a discussion starter or
presenting some findings in your work. I have one presentation already on
NEON Optimization Tips and Practices, but could really use at least one
more.
I was thinking maybe someone from Toolchain, Landing Teams, or someone with
previous experience? Would this be something you or someone on your team
would be interested in?
Let me know if you have any questions.
