14:03:29 <jskarvad> hi
14:03:45 <jskarvad> #topic news
14:04:56 <jskarvad> During last week I worked on improvement of automatic testing targeted to power consumption regressions.
14:05:43 <jskarvad> Currently I have 11 benchmarks/test cases including AB (Apache), DOTS (MySQL), Unpack (tar/gzip), Postmark (filesystem), HPL (CPU/FPU), ...
14:06:37 <jskarvad> The design is as follows: there is main tester script which can be automatically kickstarted or run from the cron on the SUT (System Under Test).
14:07:53 <jskarvad> The SUT requires external USB_TMC Power Meter to be connected (currently Chroma 66202 is supported, but I would like to add more devices including the internal sensors which are available on some servers).
14:07:59 * jsmith is here, lurking :-)
14:08:33 <jsmith> Interesting... I know that a few servers give power information via IPMI
14:09:09 <jskarvad> jsmith: that's it, there is also HP iLO2/3 and probably more
14:09:41 <jskarvad> I plan to add support for them
14:11:14 <jskarvad> The tester on SUT sends the results to collector machine which stores and presents them.
14:11:49 <jskarvad> It collects benchmarks score, time of run, average power consumption and energy consumed for each test/becnhmark.
14:12:06 <jskarvad> I am going to use this for comparison/testing of various Fedora releases.
14:12:52 <jskarvad> Hopefully there will be some results next week.
14:14:58 <jskarvad> Another news: jkaluza contributed python script that generates iMacros commands for automatic browsing through youtube, google and novinky.cz.
14:15:12 <jskarvad> The script is available here:
14:15:19 <jskarvad> http://jkaluza.fedorapeople.org/imacros.py
14:15:41 <jskarvad> iMacros is macro recorder/player plugin for Firefox and IE.
14:16:13 <jskarvad> Such approach allows us to perform cross platform power consumption comparison of WWW browsers.
14:16:25 <jskarvad> I am going to use this to check the claims from:
14:16:33 <jskarvad> http://blogs.msdn.com/b/ie/archive/2011/03/28/browser-power-consumption-leading-the-industry-with-internet-explorer-9.aspx
14:17:04 <jskarvad> And to check how the Fedora/Firefox combination stands in comparison to Windows platform.
14:18:35 <jskarvad> that's all news
14:19:43 <jskarvad> jmarko any news about the jquery thing?
14:20:34 <jmarko> jskarvad no special news I din't have time.
14:21:29 <jmarko> jskarvad but i found there are nice ways how to scroll with page whit specified speed and position
14:21:54 <jskarvad> jmarko: great
14:23:01 <jskarvad> jmarko: thanks, keep on
14:24:22 <jskarvad> any comments, ideas?
14:24:36 <jmarko> jskarvad, after rhel6.1 i will find some time to try to create some example test
14:25:06 <jskarvad> jmarko: thanks
14:27:24 <jskarvad> ok, let's move to another topic
14:28:46 <jskarvad> #topic bugs
14:30:23 <jskarvad> Short overview of PM bugs I am currently aware/working on.
14:32:32 <jskarvad> Top issues: Some USB controllers (it seems that mostly on Asus laptops) requires explicit unbind before suspend otherwise it may hang - there is kernel patch that could help, I will test.
14:33:39 <jskarvad> Fedora seems not to resume from encrypted partition that is not part of the LVM - it is probably bug in the initrd scripts, I am investigating.
14:34:24 <jskarvad> sdhci-pci module needs to be unloaded before suspend otherwise it may hang - currently I am not sure what is the source of this problem.
14:37:24 <jskarvad> There are more issues in bugzilla - I will go through them on best effort basis.
14:38:21 <jskarvad> that's all for bugs
14:41:31 <jskarvad> #topic other
14:42:10 <jskarvad> Is there M. Berta or J. Voscek or vpodzime?
14:44:01 <jskarvad> OK, so their report next time.
14:47:22 <jskarvad> that's all from me for today, anybody any comments, questions, ideas?
14:52:41 <jskarvad> ok, thanks all for attending
