05:01 zul umm.. 05:01 BenC I'm trying to retrieve the rest of the team :) === amitk [n=amit@a91-154-119-106.elisa-laajakaista.fi] has joined #ubuntu-meeting 05:03 zul ok 05:03 Hobbsee BenC: offer coffee 05:04 BenC might take beer === pkl_ [n=phillip@unaffiliated/pkl/x-764568] has joined #ubuntu-meeting 05:05 Hobbsee BenC: or beer. beer is good too, it seems. 05:05 elkbuntu add pizza to the offer and you're likely to have a winner 05:05 Hobbsee mmm...pizza... 05:05 Hobbsee BAD ELKBUNTU! 05:06 BenC Well I know rtg isn't going to be here 05:06 elkbuntu caffeinated beer (surely america has this, right?) and pizza === mc44 [n=mc44@unaffiliated/mc44] has joined #ubuntu-meeting === ogra heard pizza ? 05:06 BenC kyle left ottowa for cambridge last night 05:06 BenC so just waiting on amitk 05:07 BenC I, nm, he's here :) 05:07 amitk Sorry..i am already here 05:07 elkbuntu i win! 05:07 amitk a few minutes late 05:07 BenC Ok, welcome to the kernel team meeting 05:07 BenC Meeting info (past and present) is at https://wiki.ubuntu.com/KernelTeam/Meeting 05:08 BenC We'll start of with team status 05:08 BenC pkl_: You're first up in reverse alpha order 05:10 BenC pkl_: What's your current work load right now? 05:10 pkl_ working on some kernel flavours for Gutsy. 05:10 pkl_ some bug work and that's more or less been it. 05:11 BenC pkl_: Do you know the status of ntfs-write-support for userspace side? 05:12 pkl_ No, I believe it should be in place now. 05:12 pkl_ but that's a guess. 05:12 BenC Ok, can you check up on it, just to make sure someone isn't secretly blocking on some unknown issue 05:12 pkl_ Yeah, I'll check with Colin, 05:13 BenC ok, thanks 05:13 BenC what's your expected work for the next couple of weeks, other than the normal bugs+fixes? 05:14 pkl_ Um, bug fixing is probably going to be the main focus. 05:14 pkl_ I anticipate putting AUFS into the kernel, and testing Unionfs 2.1 (that Kyle added) with liveCDS === arthur- [n=arthur@serv2.dunnewind.net] has left #ubuntu-meeting [] 05:14 BenC yeah...the unionfs seems to be high prio 05:15 amitk pkl_: what is AUFS used for? 05:15 pkl_ AUFS = Alternative Unionfs File System. 05:16 pkl_ It is basically a re-implemented Unionfs by a third-party, which is commonly believed not to have as many bugs or issues than Unionfs 05:16 BenC is AUFS something you just want to add for people who want to use it...not for livecd this late in the cycle, right? 05:16 pkl_ It would probably be useful to have in the Gutsy kernel, especially as a fall back for people having problems with Unionfs. 05:17 pkl_ It's probably too risky for the livecd now :) 05:17 BenC ok...so the unionfs 2.1 is in lum now, expected to be included and used with this next upload? 05:17 pkl_ I think so, yes. 05:18 BenC then yeah, testing livecd with that needs to be done asap 05:18 pkl_ Kyle was having some problems with the apparmor patches and Unionfs. But that should be resolved. 05:19 BenC sounds like you've got plenty to work on :) 05:19 pkl_ hopefully... 05:20 BenC amitk: so how's things been going in the mobile team? 05:21 amitk mainly changes to the build system to decouple UME patches from core Gutsy 05:21 BenC are all the patches for lpia/ume included now? 05:21 amitk Far from it 05:22 BenC what's left to include === PriceChild [n=pricechi@ubuntu/member/pdpc.supporter.student.PriceChild] has joined #ubuntu-meeting 05:23 amitk Let me rephrase it - All that is available is included now. But there are many things that are WIP e.g. the new upstream MMC stack to support SD/SDIO, ACPI thermal optimisations, peripheral drivers, etc. 05:24 BenC Ah, ok 05:24 amitk Last couple of weeks, after changing the build system, I have committed the thermal optimisation patches to UME. All a GPL driver for Marvell SD8686 SDIO WLAN chip was committed to LUM 05:24 BenC earlier you had mentioned getting lpia arch/flavour building using the same patches, moving it to a custom-binary target 05:24 amitk s/All/also === Palintheus|afk is now known as Palintheus 05:25 amitk that is a next step yes - Moving LPIA to use the same configuration for UME custom builds 05:25 BenC either we need to rename one of those flavours to match the other, or add another capability to the build system to use the ume custom-binary patches so we don't have duplicated in debian/binary-custom.d/{ume,lpia}/patchset/* 05:27 amitk BenC: agreed. I would prefer dropping UME in favour of LPIA, but since we don't yet have a complete set of packages for LPIA, I will hold back until that happens === ..[topic/#ubuntu-meeting:ubotu] : Current meeting: Kernel Team | Calendar: http://fridge.ubuntu.com/event | Logs: https://wiki.ubuntu.com/MeetingLogs/ | 05 Sep 12:00 UTC: Edubuntu | 06 Sep 13:00 UTC: Kubuntu | 08 Sep 00:00 UTC: MOTU Team | 08 Sep 17:00 UTC: Xubuntu Developers | 10 Sep 19:00 UTC: Screencast Team 05:29 BenC amitk: ok...does ubuntu-mobile expect for ume flavour to become obsolete by gutsy release? 05:29 BenC if so, perhaps it isn't too important, knowing we'll just be ditching it in the end 05:31 amitk BenC: yes, with a caveat - LPIA should be equivalent to current UME 05:31 BenC userspace wise, or kernel wise? 05:32 amitk package repository-wise 05:32 BenC ok, that's what I figured === Mez [n=Mez@ubuntu/member/mez] has joined #ubuntu-meeting 05:32 BenC Ok...anything new and exciting in the power side for general desktop users? 05:33 BenC I imagine you haven't had much time to look at that 05:33 amitk not yet. However there isn't much on the UME side this week. So I hope to go over the powertop recommendations to make sure Gutsy already support them. 05:34 BenC excellent, I've been looking forward to that 05:35 amitk that is all from my side 05:36 BenC everything's moving along it seems 05:36 BenC amitk: thanks 05:37 BenC Now we need to go over the canonical-qa bugs real quick...see if we can get some resolution on them 05:37 Mithrandir amitk: hopefully, you'll be able to drop UME in a week or two. 05:37 BenC link is on the agenda 05:37 BenC Mithrandir: ah, good to know, thanks 05:37 amitk Mithrandir: \o/ 05:37 BenC one less build on i386 is always a plus 05:38 Mithrandir that's pending us having working lpia images by then, but it's on my plan for next week, so. === finalbeta [n=viper@d54C6865D.access.telenet.be] has joined #ubuntu-meeting 05:39 BenC Damn, I'm not sure which of the bugs are hidden from public view... 05:39 BenC bug #130804 05:39 ubotu Launchpad bug 130804 in linux-source-2.6.22 "[Ubuntu Tribe3] Cannot install by LiveCD (weybridge)" [High,Confirmed] https://launchpad.net/bugs/130804 === Mez [n=Mez@ubuntu/member/mez] has joined #ubuntu-meeting 05:40 BenC That one looks like a failure to detect IDE on the weybridge 05:40 BenC amitk: this reminds me, I have to send you a weybridge... 05:41 BenC ACTION: Ben to test livecd on weybridge 05:41 amitk BenC: if that would spare my laptop from compiling our kernels, it would be much appreciated :) 05:42 BenC amitk: I'll get it out this week :) 05:43 BenC bug #131626 05:43 ubotu Launchpad bug 131626 in linux-source-2.6.22 "Sleep wakes up but screen is blank" [Medium,Triaged] https://launchpad.net/bugs/131626 05:46 BenC that seems to be a nv bug 05:46 BenC wonder if nvidia proprietary driver fixes it 05:47 BenC bug #131661 05:47 ubotu Launchpad bug 131661 in linux-source-2.6.22 "Hibernate button on keyboard doesn't work on System76 Z62F" [Medium,Incomplete] https://launchpad.net/bugs/131661 05:47 BenC that one doesn't really sound like a kernel bug 05:52 pkern At least fglrx suspend-to-RAM breaks with SLUB allocator activated. Which is why I am here and waiting for open discussion. ;o) Maybe that could be switched back to SLAB at least until ATI fixes that issue. 05:52 BenC pkern: doubtful, slub fixes more things :) 05:53 BenC ATI just needs to fix their driver 05:53 pkern BenC: It was the only option I switched to make it work again with 2.6.22. 05:53 pkern BenC: Of course, but in the meantime we break suspend-to-RAM with fglrx for all users of Gutsy. === calc [n=ccheney@conr-adsl-209-169-124-200.consolidated.net] has joined #ubuntu-meeting 05:54 BenC pkern: but that's not a fault of ours 05:54 BenC slub fixed way too many things to make fglrx an exception for switching 05:55 BenC but we can definitely look into 05:55 pkern BenC: What did it fix? I thought it's only a speed advantage. 05:55 BenC I wont say there's no chance of us switching back...just that it's very unlikely 05:55 BenC pkern: turning it on exposed so many bugs that were hard to find with slab 05:56 BenC slub has better error checking 05:56 BenC and the speedup and reduced fragmentation is a huge advantage 05:56 BenC we should talk with some folks at AMD/ATI to see about fixing this properly, instead of disabling slub just to accomodate it 05:57 pkern BenC: I guess there can't be another flavour, right? There was a thread on LKML about it some time ago and all agree that it's ATI's fault, but so far there was no response. (It's listed in their inofficial bug tracker, but then I don't know who reads it.) 05:58 BenC we don't do separate flavours just to work around a broken proprietary driver 05:58 BenC sets a bad precedent :) 05:59 pkern It would be really nice to see this fixed in fglrx, of course. But I don't know if suspend-to-RAM should be broken if SLUB mainly helps finding bugs easier. (Which I agree with for a development version.) 05:59 BenC ACTION: Ben to get in touch with AMD/ATI to see about resolving the fglrx+slub+hibernate bug 05:59 pkern BenC: Thanks (: 05:59 BenC any other open items? 05:59 zul yep just sponsorship for uds 06:00 BenC pkern: thanks for bringing it up, I'll definitely see about getting it resolved 06:00 zul since i have an expired passport ;) 06:00 BenC zul: we're in the process of looking at who will be sponsored 06:00 zul ok 06:01 BenC kernel related sponsors have been submitted, but it's upper management that has final say 06:01 zul other than that none from me 06:01 pkern BenC: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/121653/comments/15 06:01 ubotu Launchpad bug 121653 in linux-source-2.6.22 "[gutsy] Suspend to Ram does not work on Z61m" [Undecided,Confirmed] 06:01 BenC pkern: thanks === Lure [n=lure@89-212-18-142.dynamic.dsl.t-2.net] has joined #ubuntu-meeting 06:02 BenC Speaking of UDS, this is a good time to remind everyone that now's when you should start submitting blueprints for UDS 06:02 BenC not the day UDS starts :) 06:03 BenC So if there are any features you would like to see for gutsy+1, get to crackin 06:03 BenC And I think that ends the meeting 06:04 BenC Thanks everyone, and have a good week
