crimsunfor which kernel?12:19
=== calc [n=ccheney@conr-adsl-209-169-124-200.consolidated.net] has joined #ubuntu-kernel
astronouth73032.6.20-16-generic on feisty fawn12:21
calcBenC: hello12:21
calcis there a way to build just part of the kernel?12:21
calci want to just rebuild the snd-hda-intel object12:21
crimsun03:42 < crimsun> hmm, and upstream already merged alc268 support.12:22
crimsun03:42 < crimsun> Guess Chris will get his wish without blinking.12:22
crimsunof course you parted long before that.12:22
calccrimsun: whee!12:22
calcthats cool12:22
=== calc goes to look for the patch
crimsunbut to answer your question, yes.  Use SUBDIRS=sound12:22
calci was looking in the git repo that benc controls and it didn't appear to be in there yet, but looking at kernel.org now12:23
crimsunno.12:23
crimsunhttp://hg.alsa-project.org/alsa-kernel/rev/dd701601157b12:23
crimsunupstream uses Mercurial, not git.12:24
calcoh i see12:25
calci was looking at jaroslav's kernel alsa git12:25
calcwhich must not be up to date for everything12:25
astronouth7303crimsun: were you answering me?12:25
calchttp://git.kernel.org/?p=linux/kernel/git/perex/alsa.git;a=log  <- that was where i was looking, oops :)12:26
crimsuncalc: jaroslav pushes to his git tree fairly regularly but not nearly as frequently as fixes are committed to hg.12:28
=== calc oh ok
crimsuntakashi mostly handles hg.12:28
calcer oh ok ;)12:28
calci can rip that patch and rebuild it for feisty :)12:30
crimsunastronouth7303: you can grab the source subdir and build it12:31
crimsuncalc: it'll be merged into gutsy's source anyhow.12:31
astronouth7303the only place I can find the coretemp module is from torvald's branch on kernel.org12:31
crimsunastronouth7303: ...which is the base of gutsy's current git.12:32
astronouth7303so if I build it as a module from gutsy, will it load in my current kernel?12:33
calccrimsun: yea12:33
calci tried running gutsy on my new laptop and it couldn't see to work with my intel 3945 wireless12:34
calcmaybe another bug that will be fixed soon, dunno12:34
calcwould be nice to be on gutsy by the sprint next month12:34
mjg59crimsun: Oh, my neighbour found that position_fix=1 seemed to be needed to make his new MacBook (C2D) have decent sound quality12:35
mjg59Had distortion otherwise. This was on fesity.12:35
mjg59Is that likely to be sorted upstream, or should I send you subsystem details?12:35
calclooks like 268 could use some extending support if i looking at it right, but it should at least work for basic sound after this patch12:36
crimsunmjg59: SSID, please12:38
mjg59crimsun: Is that the PCI subsystem or the codec subsystem?12:38
crimsunPCI12:38
mjg59Ok12:38
mjg59Hang on a sec12:38
crimsuncalc: Realtek already has extended support; may want to check there.12:40
crimsun(they provide a tarball based on some stable alsa-driver release)12:40
calcah cool :)12:41
calcless code i have to think about the better ;)12:41
jmgupgrading to gutsy scragged my laptop12:42
jmgsomehow it managed to hardswitch the wireless off12:42
calcjmg: did it to me too, afaict12:43
jmgi cant reenable it without booting into windows and i deleted windows ages ago12:43
calcjmg: i was on 3945 wireless12:43
jmgcalc: ipw220012:43
jmghaha 'was'12:43
calcjmg: going back to feisty fixed it for me12:43
calcer was on gutsy i meant to say with 394512:43
calchehe12:43
jmgcalc: im not sure it will fix for me12:43
jmgbecause fn-f2 didnt work in feisty either12:43
calci has a 2915abg laying around here somewhere, but it wouldn't fit in this laptop anyway12:43
jmgspeaking of which12:44
=== zul [n=chuck@CPE0006258ec6c1-CM000a73655d0e.cpe.net.cable.rogers.com] has joined #ubuntu-kernel
calcmay be a different issue than what i saw though they are similar chips12:44
jmgi need gutsy alpha 112:44
calcintel 2200bg vs intel 3945abg12:44
=== ivoks [n=ivoks@21-166.dsl.iskon.hr] has joined #ubuntu-kernel
jmgi wonder if it was something i did when i was in feisty to try and enable fn-f2 which broke it when i upgraded to gutsy12:47
jmgso im gonna try the alpha12:47
calccrimsun: yea realtek's alsa driver has much better mixer support12:47
mjg59crimsun: 8384:768012:52
crimsunmjg59: thanks, could you download and run http://www.linux-sound.info/alsa/scripts/alsa-info.sh on said machine?12:56
calcwow i turned my wireless off and then back on about 20s later and i stayed connected :)12:56
crimsunthanks, TCP!12:56
=== calc turned it back on once he realized he was on irc
calcoops ;)12:56

calcthis laptop eats batteries like nothing i've ever seen :\12:58
calc67% 1h7m12:58
calcoccasionally it drops down ~ 30m12:59
calcand that is with a 4000mAh battery12:59
jmgcalc: how does it perform on windows?01:07
calcnot sure i only ran windows on it about 5m01:11
calcneed to reinstall vista on it for dual boot later on01:11
calcit is doing that while using wireless and compiling a kernel though01:11
calcalso the processor is set to go up to full speed while under load on batteryu01:12
calcforcing it at slow setting on battery may help out01:12
astronouth7303if I build a module against the 2.6.22 source tree, will it load in a 2.6.20 system?01:13
calcmy old athlon64 laptop forced the cpu to slow speed on battery always01:13
calcso i guess its not too bad01:13
calcastronouth7303: doubtful01:13
astronouth7303the linux-source-... package has the config used to build the distributed kernels?01:21
calcyes01:23
calcyou can run dpkg-buildpackage on it to get the distributed stuff01:23
calci need to go find the power cord its kill my battery doing the build01:24

dfesersomeone tryed 2.6.21 yet?01:55
dfeser?01:56
mjg59We're not shipping 2.6.2101:56
dfeserright01:57
dfeserbut all kernels that come with feisty don't let me charge my blackberry anymore01:57
dfesersomething has changed from edgy to feisty01:58
dfesercan you tell me what it is?01:59
dfesersome change in the usb system01:59
mjg59feisty uses 2.6.2002:00
dfeseri know!02:01
dfeseri'm just trying 2.6.21 because the charging does not work anymore02:01
mjg59So, yes, lots changed between edgy and feisty02:02
dfeserwow. great answer02:02
dfeserthere is a small script called bcharge. it puts the power of a certain usb port up to 500mA if there is a blackberry connected to it. 02:03
dfeserunder edgy this was working great02:03
dfeserbut under feisty it seems as if there is something that puts the power back to 100mA after a few seconds02:04
dfeserno clue?02:07
mjg59Not off-hand, no02:08
mjg59Could you file a bug?02:08
dfesercould i what?02:10
dfeseris there a way to get the old edgy kernel to my feisty?02:11
mjg59Not really, no02:11
dfeser:-/02:11
mjg59But if you go to https://launchpad.net/bugs/+filebug you can report the problem02:11
dfeserdoes ubuntu ship any kernel sources?02:18
mjg59Yes02:18
dfeserah found it02:19
mjg59Cool02:19
dfeseri will try compiling my own kernel from these sources...02:20

EtienneGgood point08:39
JanCgrep for CONFIG_NR_CPUS & CONFIG_HIGHMEM (I suppose, I'm no kernel dev)08:42
JanC-generic is 8CPU, 4GiB RAM on feisty too08:44
JanC(for x86 32-bits)08:45
JanCI think the 64-bits kernels might have a different config08:45
EtienneGjust checked on i386, and yes, CONFIG_NR_CPUS is 808:46
EtienneGCONFIG_HIGHMEM64G is not set, downloading the -server kernel to check as we speak08:46
zulserver kernel has CONFIG_HIGHMEM64G if i remmber correctly08:49

JanCthe .config files are in the kernel header packages too (no need to download complete kernels)09:03
