RAOFjono: Yeah; iwlagn got renamed to iwlwifi (somewhere between 3.0 and 3.2, I'm not sure where)00:33
RAOFjono: There's an alias of iwlagn → iwlwifi, though, so modprobing iwlagn should have (correctly) loaded iwlwifi.00:33

ckingyep, now connected again, at last09:07
smbcking, \o/09:07
sorencking: I'm blown away by the battery life on my laptop in Precise. Thank you so much for all the work you've done on this.09:58
ckingsoren, well, a really big thanks goes to pitti for fixing a load of user space bugs that we discovered doing the original research09:59
sorencking: Well, still, you clearly did a lot of work on it, collected all the important data. The effect is astounding.10:04
ckingsoren, I also suspect a lot of fixes in the kernel that landed in 3.2 helped, so it's mainly kudos to upstream ;-)10:04
ckingbut at least we know what to expect for the next cycle ...10:05
ohsixwhat's this regarding? at least the research, is there a blag about it or something?10:07
ckingohsix, http://smackerelofopinion.blogspot.com/2012/01/improving-battery-life-in-ubuntu.html10:07
ckingohsix, lots of data from the analysis can be found in: http://zinc.canonical.com/~cking/power-benchmarking/10:09
ohsixhm i thought the devices that could use low power states already did, except for ALPM which was disabled for stabilitysomethings; will digest tomorrow, thanks for the refs10:11
ckingthere is a lot of data there, so fee free to ask questions, I will see if I can answer them sensibly..10:12
ohsixwill fwts get some related tests? or is there another test tool for people to check this stuff or is it manual investigation when things start exploding10:13
ohsixer i should mention i started reading the article before the one you posted, http://smackerelofopinion.blogspot.com/2011/12/improving-battery-life-in-ubuntu.html10:14
ohsixif some of them might have stability implications how will they be tested10:15
ohsixanyways, night :] will have more pointed questions tomorrow10:17
ckingohsix, I don't think we will put any more power management related tests into fwts.  An aspm check has been added to fwts, but that's about it really 10:18
ckingas for tools for checking this stuff, it is a little tricky - the kit I used is expensive, so it's not a thing most users can do accurately10:19
ckingbut I did make a few tools and put them into a PPA: see https://launchpad.net/~colin-king/+archive/powermanagement10:20
jwicking: do you expect your work to make a difference for bug 877560 ? any improvements in power.d/intel-audio-powersave ?10:20
ubot2`Launchpad bug 877560 in linux "Audio codec draining power when not in use" [Undecided,Confirmed] https://launchpad.net/bugs/87756010:20
ohsixcking: ah i didn't mean duplicating the results with the meter and whatnot, i meant aside from aspm; the other things mentioned in the list like quiesing usb/pci devices (presumably it's not done already for "stability") if in fact it's unstable on someones machine with it enabled, will there be some tools to assist with that10:22
ckingjwi, I think we need to test this with some accurate power measuring tools - powertop needs to be run for quite a while before we can trust the data from it - and it could be that the battery info isn't accurate10:22
ckingohsix, no tools for this, that wasn't really in the project scope - my aim was to find the low-hanging fruit that could be easily fixed10:23
ohsixi looked into doing something like that in the past but the battery type in the machines i have access to just provide the battery level from the charge controller, not any wattage or accurate gas gauge type measurements10:24
ohsixand i couldn't gut my laptop to get a meter in there :>10:24
ckingohsix, yes, so I basically had to be a bit invasive - I bypassed the battery info altogether and measured current drawn from the machine 10:25
ohsixthrough the cable?10:25
ohsixbah i could just read the article, no more silly questions10:25
ohsixif there is a sort of aggressively enable sleep even if it breaks stuff, and you want to have some people shake stuff out, i'd be interested in that as well10:26

hertonppisati, these arm bugs are waiting on verification: bug 912199 and 861296. The last one was already verified on other flavours, but to be on the safe side if it can be verified on normal omap kernel would be great, can you take a look at them?12:02

* apw pops into the office, back in a bit12:20
rbasakppisati: I just got this panic on the current precise armhf installer kernel: http://paste.ubuntu.com/826304/12:46
rbasakDoes this mean anything to you?12:46
* apw admires the view13:22
ogra_ppisati, you didnt by chance happen to stopwatch the boot with the PARTUUID parameter, did you (btw, you rock !)13:22
apwppisati, what sort of uuid did you use here?13:24
* ppisati just came back13:55
ppisatiogra_: nope, because there's a delay after mounting the fs... $something is waiting on $something else, that's why i didn't take any measure, but it was definitely faster13:55
ppisatiherton: i'll have a look13:55
ogra_ah, thats alread good news at least13:56
ogra_i'm not sure how eas it is to redo our image build process to use GPT though, i need to research that 13:56
ppisatiapw: GPT UUID, the one from the second partition13:57
apwppisati, ahh so you put both down on the disk did you ?13:57
ppisatiapw: what you mean?13:58
apwyou put both a dos partition table and a gpt down on the same disk13:58
ppisatiapw: right, it's called an hybrid-mbr (but it's actually a GPT)13:59
ppisatiapw: so the old "bios" think it's a MBR, go ahead and boot it13:59
apwvery cools, ogra_ does that give you waht you need to do the speed comparison ?13:59
ppisatiapw: and once we have access to the first partition, we can chainload the loaders+kernel (that in turn can speak GPT)13:59
ppisatirbasak: never seen that, how did you got it?14:00
ogra_apw, well, after i found out how to roll GPT partitions (and if thats possible at all with the tools on the image build server) into our images14:00
rbasakppisati: nothing different to what I've been doing14:00
apwppisati, yeah thats most excellent14:00
rbasakppisati: just an attempt to netinst14:00
apwogra_, if you are careful yu may be able to add the gpt after installing, if the first partition is aligned correctly, there ought to be enough space14:04
apwogra_, cirtianly worth checking14:04
ogra_thats the issue14:04
ogra_changing the first partition alignment might break the first stage bootloader14:04
apwnormally we round up a bit for partition 1 .. to a cylinder boundary14:04
ogra_at least on the TI images ... the rom code on tehse chips is a bit silly14:04
apwso there ought to be a bit of space in there already without moving things14:04
apwogra_, like on my laptop here there is 2048 sectors wasted at the front14:05
apw/dev/sda1   *        2048   150341631    75169792   83  Linux14:05
apwso you may have some space there by default too14:05
ogra_lucky you, for us its rather the opposite ;)14:05
ppisatiogra_: actually you don't have to add anything, you have to convert the MBR to a GPT14:06
ogra_anyway, i'll try to look into it asap14:06
ppisatiogra_: once you have an image installed, fire gdisk and it'll tell you what you have to do14:06
ogra_ppisati, with the size we currently use ?14:06
ppisatiogra_: yep14:06
ogra_oh, thats convenient14:06
apwogra_, i think there has to be enough space or something, i am sure its at least one track as i think grub hides in there14:07
apwogra_, and the gpt steals one of those blocks, but grub has redundant copies or something odd14:07
ogra_ah, well, no grub for us yet :)14:07
apwogra_, then you definatly have room :)14:08
ppisatiherton: verification-done-oneiric? or was it verification-passed?14:09
hertonppisati, verification-done-oneiric14:09
ppisatiherton: i passed 912199 but for 861296 some java madness must be done, prod GrueMaster for it14:10
hertonppisati, ok. There is a testcase there though, I think you could use it instead of playing with java stuff14:12
ppisatiherton: ah right, i forgot about it14:13
ppisatiherton: i'll do14:13

hertonlinux-image-2.6.35-32-omap 2.6.35-32.65 isn't omap4, or am I wrong?16:52
