LPC2011 Power Management Micro Conf

LPC2011 Power Management Micro Conf

[Rafael J. Wysocki]

Hello,

In the previous years we used to organize Power Management Mini Summits to discuss PM
issues, the last of which took place during LinuxCon in Boston in 2010. Unfortunately,
however, it wasn't particularly well attended and the participants generally felt that
it had failed its purpose. The power management track at the last LPC, on the other
hand, was generally regarded as interesting and successful, so there only seems to be
room for one event devoted to power management a year. For this reason, there won't be
a PM Mini Summit in 2011 and the LPC PM Mini Conference will play the role of the Mini
Summit.  To this end, in addition to the plenary sessions within the LPC PM track
there will be a possibility to discuss specific problems related to power management
in smaller groups.

If there's anything you'd like to discuss or give a presentation on related to
Power Management, please submit a proposal at
http://www.linuxplumbersconf.org/2011/ocw/events/LPC2011MC/proposals
or simply let me know.

At the moment, there are two session slots allocated.  One of them will cover
the power management development during the last year, but in that context I also
would like to discuss things that are still missing and problems to solve.
The second one will cover the idle power consumption problem and will be led
by Len Brown.  Len has a lot of experience in that area, mostly with systems
based on Intel hardware, so if you want to contribute your own observations
and/or results related to idle power, please let me know.

We will have the time for one more sessions slot, so please give me your
suggestions related to it. Also, please let me know if there's anything you'd
like to discuss in smaller groups after the plenary sessions.

Best regards,
Rafael

Hi,

Some time ago I sent the following to linux-pm and wasn't really satisfied
with the response, so here it goes again.  It is slightly outdated, because
we've already started to plan a PM meeting at the Kernel Summit, but I hope
some of you will be able to participate in the LPC PM Mini Conf too.

discuss PM-related issues, the last of which took place during LinuxCon in

If there's anything you'd like to discuss or give a presentation on related to
Power Management, please let me know, preferably by replying to this message.

We have 1.5 hours allocated in the LPC schedule for the plenary session, but
we will be able to move to another room (or a number of rooms if that's more
suitable) afterwards to discuss things in detail.

At the moment, there are two items proposed for the plenary session.  One of
them will cover the power management development during the last year, but in
that context I also would like things that are still missing and problems to
solve to be mentioned, so please tell me what they are from your point of view.

Anyway, if you are going to attend the LPC and have anything PM-related to
talk about or discuss, please let me know.

The issue of cross-bus sequencing within suspend has come up again - we
really need to work out how we make sure that dependencies between
devices that aren't accounted for in the control bus sorting we do as
standard.  This may be worth bringing up a KS also as it's device model
related.

I agree, I'll add it to the agenda of the LPC microconf.

The LPC planned schedule has recently changed so that the PM microconference
is now scheduled on Thursday, Sep. 8, 2011, at 4:45 PM.  Since the LPC
organizers have no plans for Thursday evening, we can easily extend the
discussion part pretty much as far as we want.

Please review the updated agenda at
http://wiki.linuxplumbersconf.org/2011:power_management
and adjust your plans.  Sorry for the inconveniences, if any.

Thanks,
Rafael
