14:30:14 <jskarvad> #topic news
14:30:39 <jskarvad> I was working on matahari PM agent during last week.
14:30:57 <jskarvad> It is almost completed.
14:31:06 <jskarvad> The matahari allows you to manage your Linux and Windows machines through AMQP protocol and/or D-BUS
14:31:20 <jskarvad> It provides several agents thats exports various methods/properties.
14:31:41 <jskarvad> It is especially useful for clusters of Windows/Linux machines.

14:33:12 <xkriva11> the QFM link on the wiki is not working
14:33:27 <xkriva11> ehm, QMF
14:34:03 <jskarvad> xkriva11: thanks I will forward it to matahari folks
14:34:12 <jskarvad> Our PM agent currently allows you to list available PM profiles, get active PM profile and switch the active PM profile.
14:34:27 <jskarvad> On Linux it uses tuned for PM profiles manipulation, on Windows it uses PM API.
14:34:49 <jskarvad> The matahari interface is same on both platforms, only the PM profile names differs.
14:35:25 <jskarvad> In our PM agent implementation the AMQP and D-BUS is currently fully functional on Linux.
14:35:47 <jskarvad> The Windows implementation is not yet tested.
14:36:22 <jskarvad> The experimental patch that adds the PM agent into current matahari git head is available:

14:37:14 <jskarvad> In the future we would like to add functionality for measuring power consumption and settings power caps.
14:38:02 <jskarvad> Next, short presentation about the PM news in F15 is available:
14:38:29 <jskarvad> #link http://jskarvad.fedorapeople.org/F15ReleaseParty_PowerManagement.pdf <-- PM news in F15
14:39:26 <jskarvad> Next, PowerTOP was updated to second beta (AKA 1.98) in f15 / rawhide.
14:39:55 <jskarvad> It should be in f15 stable now, it contains many bugfixes.
14:40:39 <xkriva11> were some issues from the Testing day fixed before the F15 official release?
14:41:46 <jskarvad> which issue?
14:42:42 <xkriva11> some of the issues reported on the Testing day. I aks only to know if the TD should be organised sooner in the next release
14:44:01 <jskarvad> xkriva11: good point
14:44:22 <xkriva11> of course if none of them were critical or important...
14:44:40 <jskarvad> plese note, we have limited resources
14:45:02 <jskarvad> but afaik there shouldn't be critical unresolved bugs now
14:45:31 <jskarvad> feel free to provide patches to speed things up, I am going through bugzilla on best effort basis
14:47:07 <jskarvad> but planing test day earlier in the devel phase is good idea, I will try for f16
14:48:27 <jskarvad> #topic tuned
14:48:27 <xkriva11> on the other hand with later term you will get more users who will want to see all the changes in the system
14:49:07 <jskarvad> xkriva11: both approaches has pros and cons
14:49:41 <xkriva11> I guess that one reason why the last TD had so broad response is that many people wanted to see new Gnome too
14:49:41 <jskarvad> xkriva11: in f15 we were limited by feature completeness
14:50:23 <jskarvad> xkriva11: it is no point to make TD before the features are completed
14:51:11 <xkriva11> I see
14:51:20 <jskarvad> For tuned there was spotted problem with the EEEPC SuperHybrid Engine (SHE) support.
14:51:42 <jskarvad> The original SHE settings are not restored during tuned profile switching.
14:51:49 <jskarvad> The problem is caused by missing cleanup code - I will provide patch for it.
14:52:14 <jskarvad> The nasty bug 690177 that is about timeouts during switching of tuned profiles was finally resolved, thanks to mschmidt.
14:52:29 <jskarvad> The problem was in conflicting service priorities that caused systemd deadlocks.
14:52:45 <jskarvad> If you are experiencing this problem, there is a quick/temporal workaround before the proper fix will be released - yum remove cpuspeed.
14:53:14 <jskarvad> No more topic to tuned.
14:54:03 <jskarvad> #topic other
14:54:25 <jskarvad> We got RFE - the reporter would like to have the alternate default configs for daemons/services that would be optimized for low power consumption.
14:54:46 <jskarvad> It is interesting idea but actually it requires a lot of work and measurements.
14:54:55 <jskarvad> I will add this request to our wiki.
14:55:01 <mjg59> If there are daemons that impact power consumption then those daemons need fixing
14:55:07 <mjg59> We shouldn't worry about adding support for covering up bugs
14:57:58 <jskarvad> mjg59: sure, but I think there is room for tunings, e.g. polling intervals, queue processing, etc
14:58:51 <xkriva11> Do you want to test each daemon separatelly
14:59:40 <mjg59> jskarvad: There should be no daemons that poll
15:00:37 <mjg59> Where we do end up with polling daemons (mostly due to legacy horrors), then if it's acceptable to lengthen the timeouts why wouldn't you always do that?
15:03:36 <jskarvad> mjg59: I didn't perform any analysis
15:03:54 <jskarvad> just forwarding for discussion
15:04:52 * abadger1999 notes fpc meetingwill start soon if there's quorum.
15:05:18 <jskarvad> I have no more topic
15:05:42 <jskarvad> Any PM related discussion can follow on #fedora-power
15:06:29 <jskarvad> thanks all
