desrtBenC; please re-enable it :)04:26
lamontBenC: it might be from whatever the DC machines wanted... might be good to ping elmo on the HUGETLB* stuff04:30
lamontat which point he'll say one of (a) HELL YES, (b) HELL NO, or (c) whatever04:31

fabbionemorning05:24
fabbionedesrt: TLB is sort of a problem05:24
desrthow so?05:25
fabbionebecause it adds an extra layer to the mm iirc05:25
fabbionethat slow dows things a bit05:25
=== desrt raises an eyebrow
fabbione+ it was never turned on05:25
desrtah05:25
desrtit was probably just on in my custom kernel that i was running05:25
desrtwhen you guys started shipping 64bit i switched05:26
fabbionedesrt: we can discuss these goodies for dapper05:26
fabbionehttp://bugzilla.ubuntu.com/show_bug.cgi?id=16469 <-05:28
fabbionedidn't we fix this one?05:29
desrtfabbione; i was actually rather hoping for HUGETLB in breezy05:30
desrtat least in powerpc64-smp :)05:31
fabbionedesrt: too late. it involves an ABI change mostlikey05:31
desrtarggghh05:31
fabbioneand we are truely deep freeze now05:31
desrti don't believe in freezes :)05:32
fabbionewe do :)05:35
fabbioneyou lose :P05:35
desrtdoes anyone even use ppc64? :)05:46
desrthow do i find out if ABI would be broken?05:47
fabbionedesrt: yeah quite a lot of people05:48
fabbionedesrt: there is an ABI checker in our source code05:48
fabbiones/source/build/05:48
desrtk.  i'll have a look at it at work05:53
desrtbasically, we need need need hugepages05:53
desrtand running a custom kernel in ubuntu isn't the most comfortable exercise05:54
fabbionedesrt: for dapper for dapper for dapper05:54
desrtparticularly in breezy :)05:54
desrtk.  our research is occuring now :)05:54
fabbionedesrt: why not?05:54
desrtfabbione; because you have to recompile it every time the kernel is updated05:54
fabbioneit's easy to build custom kernels05:54
fabbionenope...05:54
fabbionethat's why you make a custom05:54
desrti'm all about getting my stuff into upstream :)05:54
desrtright... but i mean... if you want the fixes in the new kernel05:55
desrtthen you have to rebuild your config against the new source05:55
fabbionewell of course05:56
fabbionegiven that you need the new fixes05:56
fabbionethe only reason why i would compile a custom kernel is if i need special features or remove unused features05:56
desrtwell05:57
desrtwith ubuntu pretty much everything is a module05:57
desrtwhich is nice05:57
fabbionebut... 05:57
fabbionefor ex..05:57
fabbionea security fix comes up on ppp05:57
desrti'd disable inotify05:57
desrtit sucks :)05:57
fabbioneand you don't use and build ppp05:57
fabbioneit's pointless to update05:57
desrtright.05:57
fabbionei agree..05:57
desrti was joking05:57
desrt*ahem*05:57
fabbioneso your upgrade path is different05:57
fabbioneidiotify sucks05:58
fabbionebrb05:58
desrthahahah05:58
desrtthat's a great name!05:58
fabbionere06:08
desrtdo you have an idea of how to do better than inotify?06:10
desrtif you do i'd seriously like to hear it06:10
fabbionei think the kernel code is ok06:14
fabbioneit's userland that truely sucks06:14
desrthmm06:15
desrtinteresting06:15
desrtin what ways do you feel this to be the case?06:15
fabbionebecause i had to debug gamin more than once06:16
desrt(hah.  i'm being such a psych)06:16
fabbioneso i read both the codes06:16
desrtahh06:16
fabbioneand i can tell you that gamin is really bad code06:16
fabbioneor at least used to be06:16
desrtok.  ya.. the gamin backend for inotify is a bit scary06:16
desrtmy problems with inotify, incidentally, are based on the kernel :)06:16
desrtit's the best interface that we could possibly have06:17
desrtbut it's still quite bad06:17
desrtalas.  bed now.06:17
desrtcheerio.06:17
fabbionegood night06:18

lamontwhen is -19 uploading?10:13
zulwhen benc gets to it? :)10:19
zulim heading home folks talk to you later10:19
lamontmjg59: HP OB900... clues on what I need to do to make sound work in breezy (or hoary, for that matter...)10:24
BenClamont: you need anything last minute?10:46
lamontBenC: just waiting for it10:46
lamontI mean, today is _almost_ over in London.....10:47
lamont(not that I'm impatient or anything...)10:48
BenChehe, ok10:48
BenCwas just about to do the upload10:48
BenCwaiting to see if I got some response for a couple of bug reports first10:49
BenCok, upload in ~10 minutes10:54

fabbioneBenC: rocking11:10
jbaileymjg59: Should the kernel stop asking us to load vesafb now, then?  Or does it still need to load it in case the user desn't have usplash11:23
jbaileymmm.11:23
jbaileyNot that it would matter at that point, given that fbcon isn't also loaded.11:23
