| * abogani waves all! | 06:06 | |
| abogani | apw: I don't take care of it anymore, you have to speak with one of the Ubuntu Studio kernel Team members... | 06:08 |
|---|---|---|
| === smb` is now known as smb | ||
| apw | abogani, oh ok, any idea who they are ? | 07:55 |
| apw | abogani, or more likely what the team is called in LP | 07:55 |
| smb | mumble seems jetlagged, too | 08:00 |
| abogani | apw, https://launchpad.net/~ubuntustudio-kernel-team | 08:07 |
| apw | abogani, thanks | 08:32 |
| abogani | apw, Thanks to you! | 08:33 |
| dileks | abogani: isnt renaming from lowlatency to preempt a reason to maintain it :-)? | 08:39 |
| abogani | dileks: lowlatency turn off tickless and enable thread irqs by default. So no preempt isn't enough. | 08:40 |
| dileks | thanks for the update, was thinking this is a renamed -rt kernel-flavour | 08:41 |
| ohsix | disable tickless huh, wasn't there a tool that measured wakeup jitter? :D | 08:43 |
| * ppisati -> brb | 09:11 | |
| * ppisati -> rush out for lunch and some grocery - later | 10:59 | |
| apw | dileks, right ... there never is a -rt patchset close to the version we are releasing on to even consider | 11:22 |
| tgardner | apw, did you get this bug report from rick about azure ? | 11:58 |
| tgardner | apw, nm, I see you commented recently | 11:59 |
| apw | tgardner, yep, at 95 reboots without reproducing ... so ... | 12:41 |
| tgardner | apw, ah, this one could be a pain in the ass | 12:41 |
| tgardner | apw, kind of wish he'd have come talk to us last week. | 12:41 |
| apw | tgardner, yeah ... they are obviously doing something different ... so ... | 12:41 |
| apw | tgardner, yeah i did talk with him, and there was no real mention of any urgency | 12:42 |
| === slangase` is now known as slangasek | ||
| tgardner | cking, what is the expected string from 'uname -m' on an i386? would it be "x86_32" or just "x86" ? | 13:23 |
| cking | tgardner, not entirely sure, /me looks it up on some old kit | 13:24 |
| ppisati | tgardner: right, there's even ppc | 13:26 |
| tgardner | ppisati, right, so I think we need to change your patch to look for x32 before checking on PAE | 13:26 |
| ppisati | tgardner: yep, better | 13:26 |
| tgardner | I should have thought of other arches when I wrote it originally | 13:26 |
| cking | tgardner, uname -m on a 32 bit atom returns 'i686' | 13:27 |
| tgardner | cking, thanks | 13:27 |
| tgardner | cking, so, searching on "*86" should be a good reg-ex ? | 13:28 |
| cking | tgardner, i think so, but make sure it doesn't match x86_64 | 13:30 |
| tgardner | cking, how about 'uname -p' on your atom ? | 13:30 |
| cking | uname -p --> i686 | 13:30 |
| cking | uname -i --> i386 | 13:31 |
| tgardner | cking, ok. given that we're qualifying the search based on 'pae', I think the general "*86" reg-ex is OK, even for AMD etc | 13:31 |
| cking | tgardner, perhaps checking uname -i is better | 13:32 |
| tgardner | cking, yep | 13:32 |
| tgardner | ppisati, you wanna respin using 'uname -i' and checking for "*86" ? | 13:32 |
| ppisati | tgardner: will do | 13:35 |
| ppisati | tgardner: actually i would prefer to avoid using any regexp | 13:35 |
| ogasawara | tgardner, ppisati: I haven't uploaded meta yet, do we want to respin an upload before I do? | 13:38 |
| ppisati | ogasawara: yep, doesn't install on arm/ppc | 13:39 |
| ogasawara | ppisati: ack | 13:39 |
| tgardner | ogasawara, probably cause this'll break armhf | 13:40 |
| apw | tgardner, as the builds worked with the tools split, it may be worth you testing backing out the -j change you did for tools (as you can repro it pretty easy) | 13:44 |
| tgardner | apw, I think I did already | 13:45 |
| apw | ahh ok | 13:45 |
| tgardner | apw, its still in quantal, but I dropped it from the other releases | 13:45 |
| apw | tgardner, you did the backport a bit different, should we standardise on your version | 13:46 |
| tgardner | apw, I'm almost positive that it was releasted to the perf binaries being removed | 13:46 |
| tgardner | related* | 13:46 |
| apw | tgardner, it would cirtainly look similar indeed | 13:46 |
| tgardner | apw, yeah, we could standardize. its a bit simpler. | 13:46 |
| apw | tgardner, ack, please do | 13:46 |
| tgardner | apw, will do | 13:47 |
| apw | ogasawara, is quantal 'good' ie can i punt some more crack into it? | 13:54 |
| ogasawara | apw: built fine, just holding off on meta till we get the pae check correct and will re-upload. feel free to shove any other crack in for the upload. | 13:55 |
| tgardner | apw, ogasawara: I'm gonna reorganize master-next a bit and cleanup some of our (my) mistakes. | 13:58 |
| ogasawara | tgardner: cool, I wanted to rebase some bits out of existence too, you go first. | 13:59 |
| apw | tgardner, ogasawara, when you are done yell and i'll rebase the bits i have onto the top | 13:59 |
| apw | (they are re-build testing now) | 13:59 |
| tgardner | ogasawara, pushed | 14:01 |
| ogasawara | tgardner: ack | 14:01 |
| apw | top - 10:06:32 up 14 days, 17:01, 1 user, load average: 450.34, 296.49, 165.35 | 14:06 |
| * apw whistles quietly | 14:06 | |
| tgardner | apw, tangerine ? | 14:06 |
| apw | goemeisa | 14:06 |
| tgardner | I built every release yesterday on tangerine. I imagine it was heating the room. | 14:07 |
| apw | heh ... i bet ... i am being utterly mean to it, -j512, just to see whether it copes | 14:07 |
| apw | and its amazingly still up | 14:07 |
| ppisati | tgardner: i noticed that :) | 14:08 |
| apw | top - 10:08:08 up 14 days, 17:03, 1 user, load average: 511.94, 359.70, 200.68 | 14:08 |
| tgardner | apw, pgraner and larry will be at 1SS on Friday at which time I will unf*ck /boot | 14:08 |
| apw | tgardner, a perfect time to scare the crap out of them by playing tunes on the fans | 14:09 |
| apw | tgardner, think you can shift the root up a bit, or will you just zap it | 14:09 |
| tgardner | apw, like they'd be able to hear an individual fan in that place. | 14:09 |
| tgardner | apw, I'll see if I can shift things around, but failing that I'll just rebuild from scratch. | 14:10 |
| apw | tgardner, ok then i should make sure the crack builds are pulling off their state properly like they are meant to | 14:10 |
| apw | tgardner, so i can put it back after | 14:10 |
| tgardner | apw, yeah, be prepared for total destruction. you _know_ how skilled I am at sys admin :) | 14:11 |
| apw | tgardner, it all designed with fungible machines in mind, just i've never funged it | 14:11 |
| apw | i should really kill it all off on gomeisa and just move it to tangerine | 14:12 |
| apw | to prove it works and is documented | 14:12 |
| tgardner | apw, well, here is your chance. you could switch to tangerine for awhile. | 14:12 |
| apw | tgardner, ok friday you say ? | 14:13 |
| tgardner | apw, that was the last I heard | 14:14 |
| * apw adds it to his list | 14:14 | |
| dileks | does sth like snapshots.u.c exist? | 14:15 |
| * dileks wants to downgrade resolvconf | 14:15 | |
| xnox | dileks: it's called launchpadlibrarian | 14:16 |
| ogasawara | apw: pushed my changes, she's all yours | 14:17 |
| ppisati | ogasawara: tgardner: patch sent to the ml - in the end i used a =~ | 14:18 |
| tgardner | ppisati, ack | 14:18 |
| apw | ogasawara, ok pushed overlayfs.v13 update | 14:20 |
| ogasawara | apw: ack | 14:20 |
| tgardner | ogasawara, I'll pick up ppisati pae fix | 14:21 |
| ogasawara | tgardner: ack | 14:21 |
| ogasawara | apw: you sure you pushed it? | 14:22 |
| ogasawara | apw: I'm not seeing it | 14:22 |
| apw | ogasawara, i failed due to incompetance, try now | 14:22 |
| ogasawara | apw: much better | 14:22 |
| tgardner | ogasawara, get your whip out | 14:23 |
| ogasawara | tgardner: I dunno, he might actually enjoy that | 14:23 |
| tgardner | kinky englishman | 14:23 |
| apw | might, how little you know me | 14:24 |
| ogasawara | hehe | 14:24 |
| tgardner | ogasawara, ok, I'm gonna whack master-next yet again to cleanup the PAE patch. OK ? | 14:25 |
| ogasawara | tgardner: ack | 14:25 |
| arges | ppisati, hello. is there a wiki for pandaboard setup? just got one in the mail, so probably be setting that up sometime | 14:26 |
| tgardner | ogasawara, pushed. now we should be able to start build and boot testing. | 14:26 |
| tgardner | ppisati, I assume you've tested your patch on arm ? | 14:26 |
| * cking upgraded to quantal and sees no breakages | 14:26 | |
| ppisati | tgardner: yep, that | 14:26 |
| ppisati | s why it took me so long | 14:26 |
| ppisati | arges: uhm | 14:26 |
| ogasawara | tgardner: cool, will get things kicked off | 14:26 |
| ppisati | arges: don't think so... | 14:26 |
| arges | ppisati, ok just pandaboard.org... read through that? | 14:27 |
| ppisati | arges: no no, wait | 14:27 |
| tgardner | ogasawara, yeah, I've got my hoover moaning as well | 14:27 |
| ppisati | arges: https://wiki.ubuntu.com/ARM/OmapDesktopInstall | 14:28 |
| ppisati | arges: just dd the img, and you are done | 14:28 |
| arges | ppisati, perfect thanks | 14:29 |
| apw | arges, yeah if its harder than dd image -> sd card, insert and power on, you are doing it wrong | 14:33 |
| dileks | xnox: and how do I get the diverse sources? as "http://librarian.launchpad.net/ is a file repository used by Launchpad. "? | 14:35 |
| tgardner | cking, do you have a non-PAE atom in your collection ? | 14:35 |
| arges | apw, yea much easier than the other embedded boards i've played with | 14:36 |
| cking | tgardner, yep, I can dig one out of the pile | 14:36 |
| tgardner | cking, it would be good to test the upgrade path from precise -generic to quantal. | 14:36 |
| tgardner | i wanna make sure it fails. | 14:37 |
| cking | tgardner, just checked, all my old atoms are N270s, which by default run -pae | 14:38 |
| tgardner | cking, ok | 14:38 |
| * cking wonders if there is another way to test, how about in virtual box? | 14:39 | |
| tgardner | cking, dunno, I've not used VB | 14:39 |
| tgardner | ogasawara, I'm still getting build failures in perf, so it looks like it may really not be parallel build safe. | 14:41 |
| smb | Hm, I think with kvm you can influence the cpu emulation... | 14:41 |
| cking | looks like VB has PAE enable/disable mode in the config | 14:42 |
| tgardner | ogasawara, I pushed master-next with a patch to disable $(conc_level) when building perf. | 14:43 |
| smb | cking, Using virt-manager with kvm seems to allow to set some cpu type and you can change cpu flags... Never tried that, though | 14:44 |
| xnox | dileks: you need to manually work through http://launchpad.net/ubuntu/+source/package find the binary build you want and download individual debs | 14:49 |
| dileks | hmm | 14:51 |
| dileks | https://launchpad.net/ubuntu/precise/amd64/resolvconf | 14:51 |
| dileks | looks like this gives me an overview of all versions | 14:51 |
| cking | hrm, can't seem to install precise-i386 with pae disabled in virtualbox | 14:54 |
| apw | cking, heh you won't be able to, the CD is pae | 14:55 |
| apw | i think the only official way to get there is to install oneiric i386 and upgrade | 14:55 |
| cking | doh, yep, /me downloads oneiric -i386 and tries | 14:56 |
| jsalisbury | apw, just let me know if you want me to help bisect bug 994870 | 14:56 |
| ubot2 | Launchpad bug 994870 in linux "kernel panic on boot with hyper-v" [Critical,Confirmed] https://launchpad.net/bugs/994870 | 14:56 |
| apw | jsalisbury, ack though it needs some special patch handing i think and as we have nothing to test on right now ... | 14:56 |
| jsalisbury | apw, ok. I'll keep a close eye on it. | 14:56 |
| ogasawara | tgardner: ack | 14:59 |
| tgardner | ogasawara, ok, mine built OK this time | 15:01 |
| ogasawara | tgardner: will re-kick off my builds here | 15:02 |
| tgardner | ogasawara, I'm bisecting a backlight regression on my Dell 1710 that occurred somewhere between -rc5 and -rc7. Once I know what it was I'll work with upstream to get it fixed. | 15:07 |
| ogasawara | tgardner: ack | 15:15 |
| * ogasawara back in 10 | 15:15 | |
| apw | ogasawara, man he can eat fast some days | 15:19 |
| tgardner | apw, its these new management techniques she's been learning | 15:21 |
| cking | parallel processing perhaps? | 15:23 |
| apw | cking, shoving half in each end perhaps | 15:27 |
| cking | apw, one can only speculate... | 15:27 |
| apw | cking, its likely illegal to do more | 15:28 |
| cking | :-/ | 15:29 |
| smb | One can speculate about some rolling on the floor going on somewhere... :) | 15:30 |
| tgardner | ogasawara, quantal build succeed ? | 15:57 |
| ogasawara | tgardner: looking good so far... powerpc is always the longest to get confirmation | 15:58 |
| tgardner | ogasawara, thats likely to be OK. I don't think we changed any arch specific stuff, did we ? | 15:59 |
| ogasawara | tgardner: only big changes were the overlayfs bits but I don't believe that has anything arch specific | 16:00 |
| ogasawara | tgardner: have we been able to get any test confirmation for non-pae hardware? | 16:00 |
| tgardner | ogasawara, I think cking is working on a VB test | 16:01 |
| cking | yep, it's taking a while to install and upgrade in VB :-( | 16:01 |
| smb | afternoon went where the morning did do just before... | 16:02 |
| tgardner | smb, I'm gonna add you as s-o-b or acked-by on these xen-acpi patches, then push 'em | 16:03 |
| smb | tgardner, I should be as s-o-b on those I pushed already | 16:04 |
| tgardner | smb, right | 16:04 |
| cking | hrm, "About 4 hours remaining" on the upgrade does not bode well | 16:04 |
| tgardner | smb, several are cherry-picks from Konrad | 16:04 |
| smb | tgardner, Ah right, I did not change the s-o-b unless I meddled with one since the version you had | 16:05 |
| smb | So yeah, feel free to add me to the remainder | 16:05 |
| tgardner | smb, I'll make sure you're in the chain of responsibility :) | 16:06 |
| smb | tgardner, I am sure you do :) | 16:06 |
| * smb really likes the 20W less power usage on idle for his AMD box... | 16:07 | |
| cking | smb, calculate how power is saves and turn it into beer money | 16:08 |
| cking | s/how/how much/ | 16:08 |
| * smb looks at one additional pint a month... | 16:11 | |
| smb | If my maths are not too much influenced by desire | 16:11 |
| tgardner | ogasawara, re: backlight regression, -rc5 good, -rc6+ bad | 16:18 |
| ogasawara | tgardner: anything obvious from the changes between the two? | 16:19 |
| tgardner | ogasawara, not really. I'm gonna start a real bisect | 16:19 |
| tgardner | there are a half dozen gpu patches, but I'm not gonna make any assumptions | 16:20 |
| sforshee | tgardner, have you determined which backlight interface is being used on the machine? That might help limit your bisection | 16:29 |
| tgardner | sforshee, haven't looked | 16:30 |
| tgardner | that would require some assumptions | 16:30 |
| sforshee | how so? | 16:31 |
| tgardner | sforshee, it assumes the regression is under drivers/gpu right ? | 16:32 |
| tgardner | it might be a platform issue | 16:32 |
| sforshee | tgardner, not necessarily | 16:32 |
| sforshee | you have to check which of the /sys/class/backlight/*/brightness files is changing when you change the backlight | 16:32 |
| sforshee | it might not be a gpu backlight driver | 16:33 |
| sforshee | in which case looking under drivers/gpu is pointless | 16:33 |
| tgardner | sforshee, which is why I'm doing an unrestricted bisect | 16:33 |
| tgardner | sforshee, acpi_video0 is the backlight class | 16:34 |
| sforshee | tgardner, nothing in your range from drivers/acpi or drivers/platform/x86 looks related, so I guess the unrestricted bisect probably is your best bet | 16:36 |
| sforshee | I have a hard time imagining what caused the regression | 16:37 |
| * ppisati -> gym/workout | 16:49 | |
| tgardner | sforshee, looks like its homing in on nouveau, which is not really surprising | 16:55 |
| arges | tgardner, hey tim. if i want to test wireless-n performance, is iperf a good tool to use? | 17:27 |
| tgardner | arges, tahts what I use to sort of smoke test it | 17:27 |
| tgardner | to smoke* | 17:27 |
| arges | tgardner, ok just default flags/window size? | 17:27 |
| tgardner | arges, yep. to make it really whine, though, try a bi-directional test | 17:28 |
| arges | tgardner, ok i'll give that a shot.. i just can't seem to get more than 50Mb/s on 802.11n using iperf on a couple of machines | 17:29 |
| arges | both are 2x2s, and I think the router is also a 2x2..but need to make sure | 17:30 |

| apw | herton, where are we in the precise SRU process | 17:44 |
| herton | apw, testing week | 17:45 |
| tgardner | sforshee, I bought a copy of the 802.11-2012 spec for $5 from IEEE. I think its got all of the amendments applied, so its a lot more readable. | 17:45 |
| herton | apw, new kernels should be prepared next week | 17:45 |
| apw | herton, i am likely to have a patch which needs to be out as soon as humanly possible | 17:46 |
| herton | bjf, henrix ^ | 17:46 |
| arges | tgardner, going in the other direction (wired to wireless computer) results in a higher bandwidth reading, not sure if that's normal | 17:46 |
| apw | ok that sounds ok then i think, this one should be out before we have confirmation | 17:46 |
| tgardner | arges, I typically use only one wireless station and a wired server | 17:47 |
| apw | herton, i may ask you to slide out a very thin kernel update in between this and next cycle, so lets circle before you build the next one if thats ok | 17:47 |
| tgardner | arges, remember that its a half duplex medium | 17:47 |
| apw | hallyn, hopefully it won't be necessary, and your normal cycle will be quick enough | 17:47 |
| apw | herton, ^^ | 17:47 |
| arges | tgardner, yea need to probably shut off other devices | 17:47 |
| apw | herton, so see this as just a head up for now | 17:47 |
| herton | apw, ok, we still have this precise kernel on testing, bug 991925 | 17:48 |

| tgardner | arges, I doubt that is a configuration taht is supportable. you'll need the dkms driver from the backport release. | 18:03 |
| arges | tgardner,ok thanks | 18:05 |
