Fudgehi how can i find out which module is responsible for sound with Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)12:03
apwFudge, does lspci -nnvv tell you?12:18
apwbut if its HDA it'll be that the intel hda driver with a code specific to the card12:18
apwFudge, and then if so aplay --list-devices may help12:19
apwcard 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]12:19
apwfor exmaple for me i get that12:19
Fudgeapw  strange, at the bottom of the card in the first -nnvv you said, i get Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel12:20
Fudgecard 0: SB [HDA ATI SB], device 1: ALC889 Digital [ALC889 Digital]12:22
apwso thats the one then12:23
Fudgeits a pretty new gigabyte amd board, the sound is pretty shocking seemlingly12:25
Fudgeto track down sound probs would it be something like, the module, alsa, pulse im not sure where to start12:26
apwFudge, what are the symptoms 12:26
Fudgewhen it boots the sound is very crackly12:26
Fudgenot like the standard sometimes record static you used to hear on a album12:27
Fudgelike a big round record ...12:27
apwdiwic, what is that option to ignore the hda pointer thingy 12:27
Fudgethis actually echos several times for everything playing, if i get another stream going under a different user like root and make espeak say something, it clears up12:27
diwicapw, looking for https://wiki.ubuntu.com/Audio/PositionReporting ?12:27
diwicapw, not sure if that's what you mean with "pointer thingy"12:28
apwdiwic, yep thats the one ... thanks12:28
apwFudge, that is a good place to start12:28
diwicA good place to start is https://wiki.ubuntu.com/DebuggingSoundProblems .12:29
apwdiwic, thanks12:29
apwFudge, have at it, and let us know... do file a bug12:29
diwicbut yeah, for crackling sound PositionReporting is one thing to try12:29
Fudgediwic  yes thank you, apw  I will try now12:30
diwicFudge, what ubuntu release?12:30
Fudgecurrent alpha212:30
diwicoh12:30
diwichaven't heard of any crackling stuff for 12.04; and we fixed ATI around natty I think12:31
Fudgeok the first fix1 made the audio come good in about five seconds12:42
=== TeTeT_ is now known as TeTeT
Fudgethe second fix2 made it not cracle but my sound was breaking up12:42
Fudgewhich sux when i rely on text to speech lol, i now jsut tried the udev mod and it didnt appear to make a lot of difference12:43
ppisatitgardner: refrain from uploading P/omap4, i want to rebase it on top of latest master today12:48

Fudgeapw  ubuntu-bug audio just asks if i would like to bug about a pulse crash, which i think may have been my fault anyway12:50
* tgardner bounces gomeisa for kernel update13:35
apwtgardner, man we are getting a lot of those these days13:41
tgardnerapw, what? kernel updates?13:41
apwtgardner, yep13:41
tgardnerapw, it took my mirror almost 8 hours to sync yesterday13:42
apwtgardner, oh i wonder, could they have sync'd only to -security by accident13:50
apwtgardner, so you were waiting on that poor puppy13:50
tgardnerapw, dang, looks like gomeisa didn't boot again13:50
apwtgardner, ogasawara, meant to ask ... do either of you have non-native build runes for powerpc at all ?13:51
tgardnerapw, not me13:51
ppisatiapw: something along the line - export $(dpkg-architecture -apowerpc); export CROSS_COMPILE=powerpc-linux-gnueabi-; fakeroot debian/rules clean binary-$ppc?13:54
ppisatiapw: bear in mind that i guessed some values13:54
=== dduffey_afk is now known as dduffey
apwppisati, do we have cross compilers installed somewhere ?13:59
ogasawaraapw: sorry, I don't have any non native build runes either14:03
apwogasawara, and how many hours does one build take there ?  one flavour ?14:05
tgardnerogasawara, gomeisa is hosed. gonna take me a bit to restore the runes for looking at the remote console. what a pain in the ass.14:05
ogasawaraapw: 2-3hrs?14:05
ogasawaratgardner: ugh, hosed after an update?14:06
apwtgardner, i have been investigating why the chroot build stuff doesn't honour the http_proxy etc parameters one might offer it ... seems that we have two places the environ gets trashed, one at the first sudo and the other at the individual schroot commands ... any objection to me adding options to let those through?14:06
tgardnerogasawara, I suspect its like last time, the initrd didn't get rebuilt correctly14:06
apwogasawara, it wouldn't be the first time that it died cause update didn't take right rather than the update itself14:06
apwwhat he said14:06
apwogasawara, when you build test, do you just do one flavour or the lot ?14:07
ogasawaraapw: I usually just do one14:07
ogasawaraapw: I'm too impatient to do the whole lot14:07
apwhas anyone tried using the qemu style thing like we do for a real arm build ?14:07
apw(for power builds)14:07
tgardnerapw, I've no preference. whatever makes it work properly.14:07
ogasawaraapw: I haven't14:08
tgardnerapw, I did awhile back. qemu didn't work very well14:08
apwtgardner, i can't think of any good reason its not safe, given we pass that script in the tree anyhow so there is no security in it14:08
* apw sighs ... its like arm all over again, without the working builds14:08
tgardnerapw, well, since I don't know what you're intending, I have no objection :)14:08
apwtgardner, i am intending to add -E to the sudo incantion in the scripts, and a -p to the schroot ... which will pass the environ across allowing apt to use the proxy one has in your enviroment14:09
tgardnerapw, on tangerine and gomeisa ? I didn't think we had a proxy14:10
apwtgardner, this lets you use the squid-deb-proxy style proxies to install new chroots14:10
apwtgardner, there not at the moment, though in your new world order having one on the gateway would maek sense14:10
apwtgardner, and we should consider getting something cheap for that box, to keep gomeisa as a real machine14:10
tgardnerapw, I've got a nice AMD server thats not worth much as a builder14:11
apwtgardner, but here i want to use the scripts at home and while i could get them to work with apt-cahcher-ng (it has some magic to support that use case) i can't with squid, unless i can use http_proxy14:11
apwto get them installed, then i can add a proxy command inside and all is good14:11
apwtgardner, if you run these scripts again they just build the missing ones right ?14:12
tgardnerapw, yep, shuold14:12
tgardnerapw, you're talking about the stuff under kteam-tools/chroot right ?14:13
apwtgardner, indeed.  i want to have the exact same stuff and not have to fight them every time14:13
apwtgardner, that and i just changed proxies for convienience14:13
tgardnerapw, ok, commit the changes and I'll test on my end14:14
apwtgardner, am just seeing if i can easily add the required proxy config inside the chroot if it is specified outside, if so that will rock14:14
ppisatiapw: dunno, never messed with ppc14:16
ppisatiapw: how about the debian/embedian one?14:18
ppisatiapw: http://psas.pdx.edu/DebianCrossCompilerHowto/#index1h114:18
apwppisati, that might work, will put that on my list to poke14:21
apw2.5 hours is excruciating14:21
ppisatiapw: i'm testing right now14:21
ppisatiapw: P kernel?14:21
apwppisati, yeah thats the one i want to be able to build and test14:21
ppisatiapw: it's compiling14:24
apwppisati, interesting, let me know how long it takes14:25
ppisatiapw: first install the embedian cross compiler14:25
ppisatiapw: then14:25
ppisatiapw: export $(dpkg-architecture -apowerpc);14:25
ppisatiapw: export CROSS_COMPILE=powerpc-linux-gnu-14:25
ppisatifakeroot debian/rules clean binary-powerpc14:25
apwppisati, and where do i get the embedian cross comp ?14:27

apwdoh14:28
ppisatithey are still at 4.4 btw14:28
apwppisati, still interesting for a quick build14:29
apwthanks, will play with those and see if they at least make a kernel for me14:29
apwbjf, did you upgrade your hed in the end ?14:30
apwbjf, i think you said you had no problems didn't you with a live-cd ?14:30

scott-workcan someone (maybe apw ) review the lowlatency kernel in REVU?  http://revu.ubuntuwire.com/p/linux-lowlatency16:17
scott-workif someone here were also a MOTU and can advocate it, well then, that would exceedingly awesome as well :)16:18
hertonppisati, what do you mean with POLA?16:31

ppisatiherton: Principle Of Least Astonishment16:47
ppisatiherton: don't make any changes that could break someone else work16:47
hertonppisati, ok, wasn't sure of what the acronym stands for, first time I see it I think :)16:49
apwsmb, fyi i have pushed a fix onto the top of the chroot build scripts that let you use an exported http_proxy variable17:19
apwsmb, export http_proxy=http://name-of-squid-host:8000/17:19
apwsmb, and that will use the proxy for the initial installation of the chroot, and also insert that proxy configuration into the inside of the chroot as well so its configured for good17:20
smbapw, Ah ok. Should have a look at taht17:20
apwsmb, and ... if you have them and change your proxy, rerunning the command will update the internal config17:20
=== jsalisbury changed the topic of #ubuntu-kernel to: Home: https://wiki.ubuntu.com/Kernel/ || Ubuntu Kernel Team Meeting - Tues Feb 14th, 2012 - 17:00 UTC || If you have a question just ask, and do wait around for an answer!
smbapw, Ah, so it would have actually used http_proxy for the initial deboostrap17:22
smbapw, Oh, ok one had to preserve the environment, too17:24
tgardnerapw, looks good17:25
apwsmb, yeah you need the -E to get the http_proxy through to the dbootstrap, then i insert the proxy config for every more17:26
smbnice17:26
apwsforshee, fyi there are three .sh scripts with msmtp which give you a queue and queue runner abstraction.  seem to work here for me17:57
=== maxb is now known as Guest79372
sforsheecool, I'll check that out17:57
apwsforshee, i just modded the enqueue to always swan the queue runner so it either sends them immediatly, or they get queued17:58

hertonppisati_, thanks, looking19:21
hertonppisati_, everything good, pushed19:28
ogasawarartg_: I notice there is an ndiswrapper dkms package in main -> https://launchpad.net/ubuntu/+source/ndiswrapper so do we even need to carry this in the kernel?19:31
rtg_ogasawara, indeed? I'd be happy to drop it from the kernel.19:31
rtg_ogasawara, there seems to be 2 source packages19:32
rtg_but the dkms version is current19:32
rtg_ogasawara, yeah, I'm happy to drop it.19:33
ogasawarartg_: it was already disabled in the Makefile, so it shouldn't have any affect if we just yank it.19:34
ogasawarartg_: I'll rip it out and push19:34
rtg_ogasawara, well, that makes it really easy :)19:34

broderhey, has anybody looked at bug #898003? it's been sitting in the sponsorship queue for over 2 months now21:18
ubot2`Launchpad bug 898003 in linux "usbip source is maintained in kernel tree now" [Low,Confirmed] https://launchpad.net/bugs/89800321:18
broderi'm wondering whether or not it would be plausible to incorporate the usbip userspace pieces into the kernel package build (there's a client, a server, and a library), or whether we should keep snapshotting the source from the kernel into a separate source package21:18
tgardnerbroder, looking21:19
tgardnerbroder, this is still a staging driver. while we have a mechanism for building and distributing applications from the kernel source tree, I'm not sure I wanna bother with a staging driver.21:23
brodertgardner: ok. that's reasonable. it doesn't seem like it's going through a whole lot of churn anyway21:25
broderi'll work on updating the separate package21:26
tgardnerbroder, maybe we can pick it up when it gets promoted to mainline21:26
