14:05:55 <HanzZ> Hi
14:06:08 <jskarvad> hi HanzZ
14:06:33 <jskarvad> hi all
14:07:16 <jskarvad> HanzZ: thank you for your recent work on powertop patch
14:07:58 <HanzZ> :)
14:08:05 <jskarvad> last week news:
14:08:09 * HanzZ hopes upstream will accept it
14:08:18 <jskarvad> #topic news
14:08:51 <jskarvad> HanzZ created patch for powertop, that allows to list all suggestions from
14:08:51 <jskarvad> powertop as shell script commands:
14:09:02 <jskarvad> #link http://bughost.org/pipermail/power/2011-June/002233.html <-- proposed powertop patch
14:09:18 <jskarvad> He also worked on a script for tuned that allows to turn this output to custom tuned profile.
14:09:34 <jskarvad> The patch was sent to powertop upstream.
14:09:50 <jskarvad> Currently there is a discussion about the benefit of this patch and  if it will be accepted or not.
14:10:18 <jskarvad> If you are interested in this feature e.g. if you like or dislike it, please join the discussion at power@bughost.org mailing list:
14:10:29 <jskarvad> #link https://bughost.org/mailman/listinfo/power  <--- powertop mailing list
14:10:33 <HanzZ> Well, I plan to finish that script this week :)
14:10:44 <jskarvad> HanzZ: np
14:10:53 <HanzZ> but lets wait for end of that discussion on powertop list :) who knows how it will end
14:11:13 <jskarvad> in case it will not be accepted, we will have to use conversion from the html output
14:11:30 <jskarvad> it is also the way
14:12:42 <jskarvad> Next info, I finished and successfuly tested the matahari PM agent for Linux/Windows, that allows you to set PM profiles remotely through dbus/qpid.
14:13:12 <jskarvad> On Linux it uses tuned, on Windows it used powrprof.
14:13:34 <jskarvad> The functionality was tested on F15 / Windows Server 2008 R2.
14:13:46 <jskarvad> Created patches and bugfixes were handed to matahari team.
14:14:09 <jskarvad> Hopefully this feature will get into f16.
14:14:44 <harish> hi all. is the Fedora APAC ambassador's meeting on?
14:15:06 <jskarvad> harish: hi, on #fedora-meeting-1
14:15:18 <harish> jskarvad, thanks.
14:15:26 <jskarvad> harish: np
14:16:41 <jskarvad> Next, I pushed pm-utils-1.4.1-8 update that should fix AVCs during F15 suspend/hibernate, bugs #710928, #710890.
14:16:47 <jskarvad> It is in update-testing now.
14:17:07 <jskarvad> Please give it some positive karma if it works for you.
14:19:01 <jskarvad> Next info, jvoscek worked on experimental patch for cronie that should add PM capabilities (e.g. similar thing that windows have for services).
14:20:08 <jskarvad> His idea was to add special PM tag (implemented as comment for backward compatibility) that describes the levels of battery on which the script is allowed to run if the machine is running from battery.
14:20:35 <jskarvad> If the battery is not enough charged, the task can be postponed several times (described by other meta tag).
14:21:29 <jskarvad> He created patch for run-parts to support /etc/cron.* with PM markings in each script header.
14:21:54 <jskarvad> He also created patch for cronie to support crontabs with such PM markings.
14:22:14 <jskarvad> He evaluates scomes score for 54 cron scripts from F14 and created experimental tags for them.
14:22:27 <jskarvad> His patches needs some edits, but I think it is interesting idea.
14:22:35 <jskarvad> I will put his results on our wiki soon for discussion.
14:23:24 <jskarvad> that was all last-week-news
14:24:19 <HanzZ> :)
14:24:50 <jskarvad> #topic other
14:25:18 <jskarvad> Last time there was an unfinished discussion about one RFE proposed to PM SIG.
14:25:35 <jskarvad> It was about creation of experimental alternative configs targeted to aggressive power savings.
14:25:59 <jskarvad> I still don't think this idea is a junk.
14:26:42 <jskarvad> I did a very quick (5 min) overlook of my fedora configs and I still think there is a room for such experiments.
14:27:10 <jskarvad> Some ideas: e.g. increase polling interval for smartd to 60mins or more
14:27:22 <jskarvad> increase prelink intervals
14:27:32 <jskarvad> increase maxpoll interval for ntpd
14:27:47 <jskarvad> shorten queue timeouts for sendmail/postfix
14:28:15 <jskarvad> increase number of pre-spowned processes
14:28:25 <jskarvad> etc.
14:28:44 <jskarvad> Of course not a big win, but at least interesting experiment.
14:28:56 * HanzZ has to read backlog :)
14:29:33 <jskarvad> Hanzz: ^^ some practice with wattmeter
14:30:00 <HanzZ> you mean to check what the benefit from those changes would be, right?
14:30:41 <jskarvad> probably very small, but we could try
14:30:53 <HanzZ> Well, I could measure those browsers too :)
14:31:04 <jskarvad> that's another part
14:31:10 <jskarvad> I count with you ;)
14:31:33 <HanzZ> yeah :) but once that meter will be connected and so on :)
14:31:49 <jskarvad> we have dedicated machine with wattmeter connected
14:32:07 <jskarvad> np at all
14:32:14 <HanzZ> :)
14:32:25 <HanzZ> looking forwatt to it :)
14:32:27 <HanzZ> ;)
14:32:58 <jskarvad> about the alternative configs, I wil add this idea to our wiki also (at least)
14:33:09 <jskarvad> it is not prio
14:33:14 <jskarvad> only idea from some user
14:34:27 <jskarvad> defaults should be good enough, and if not it should be fixed (as noted in last meeting)
14:35:19 <jskarvad> Anything more to discuss?
14:35:37 <HanzZ> I don't think so :) I know what to do :-P
14:35:57 <jskarvad> great, thank you for your interests and contribution to PM
14:36:06 <HanzZ> np
14:36:32 <jskarvad> I will be on vacation next week, so the next meeting is scheduled on 2011-06-22
14:37:02 <HanzZ> enjoy :)
14:37:24 <jskarvad> HanzZ: thanks
14:38:17 <jskarvad> that's all for today, letting approx. 5 minutes for comments
14:40:09 <GlenK> so someone told me to inquire here after the meeting if anyone knows how to adjust the fan speed on an nvidia card if I'm using the nouveau driver.
14:41:14 <jskarvad> GlenK: I am not sure if it is supported
14:41:52 <GlenK> jskarvad: well, the nouveau wiki says something like use the usual i2c method.  but I have no idea what that means.
14:43:06 <jskarvad> GlenK: please move to #fedora-power, I will end the PM meeting now
14:43:21 <jskarvad> and I will try to reply to your question there
14:43:50 <jskarvad> thanks all
14:43:54 <jskarvad> I will end the meeting in 5
