glickhey can anyone recommend some good reading to start cutting my teeth on kernel development?12:43
crimsunkernelnewbies.org should still be around.12:44
glickso linux device drivers and understanding the linux kernel is probably the two most important books to read12:47

dokohow do I build just one flavour without building the others?09:48
fabbionedoko: check debian/rules, you can specify flavour or FLAVOUR.. can't remember offhands09:49
fabbionedoko: or move away the configs you don't want from debian/config/$arch09:50
fabbioneand use binary-debs target09:50
Mithrandirdoko: https://wiki.ubuntu.com/KernelMaintenance#head-898bc4657c398ebb0d3d70597997cb9956d9b2c909:50
dokook, thanks. now I have to find out why an addition to debian/config/powerpc/sp3 is unseen ...09:51
dokoMithrandir: did look at it, but that didn't answer my question09:51
Mithrandirdoko: uh, then you meant to ask another question than you did.09:52
raffytaffyhas paravirtualization been added rescently?09:52
fabbionedoko: be careful to what you add to the configs.. i suggest you do this...09:52
fabbioneexport LC_ALL=C09:52
fabbionecd debian/config/$arch09:53
fabbioneremove the option you want to change in all config.*09:53
dokofabbione: just an additional driver09:53
fabbionefakeroot make -f debian/rules updateconfigs09:53
fabbioneit will prompt you for the question09:53
dokoahh, ok09:53
fabbioneif it doesn't it means something else is required to enable it09:53

PhinnFortwhat is the lowlatency kernel?11:17
JoseStefanBenC, here?11:17
PhinnFortis it realtime-ish for sound editing and the like, or soft realtime, for desktops?11:17
crimsunPhinnFort: identical to -generic save preempt is enabled and hz is 100011:17
PhinnFortah, ok11:18
PhinnFortno preempt big kernel lock, and the like?11:18
crimsunPhinnFort: it's nowhere close to realtime, but yes, it's more suitable for audio and video work. The use case is UbuntuStudio.11:18
PhinnFortplain preempt?11:18
JoseStefani think bug 84964 is still alive :(11:18
crimsunPhinnFort: the former. Full preemption within the scope of 2.6.20.11:18
PhinnForthow many of con-kolivas patches does .20 include?11:19
JoseStefanHow can i provide boot text for a daily-live, without the use of a digital camera (or a lot of typing) ?11:19
PhinnFort*do you know...11:19
=== benh [i=[U2FsdGV@gate.crashing.org] has joined #ubuntu-kernel
benhheya folks !11:19
crimsunPhinnFort: none.11:19
mjg59Hi Ben11:19
benhis the feisty kernel based on 2.6.20 "bare" or 2.6.20.2 ?11:19
crimsunPhinnFort: (unless they were merged into 2.6.20)11:19
crimsunbenh: .3, at least11:20
benhah ok11:20
PhinnFortcrimsun: that was what i was trying to ask;)11:20
benhso the ilog2 bug has been properly reverted...11:20
benhgood11:20
benhRevert "[PATCH]  LOG2: Alter get_order() so that it can make use of ilog2() on a constant"11:20
PhinnForti know his scheduler is scheduled to be included soon11:20
PhinnFortthough11:20
benhwithout that, random mem corruption on ppc ... no fun :-) should be all right in .311:20
benhanother questing while there...11:20
benhwhy 2 separate CDs for PS3 vs. other powerpc ?11:21
crimsuna benc question (I don't know offhand, sorry)11:21
mjg59benh: http://git.kernel.org/?p=linux/kernel/git/bcollins/ubuntu-2.6.git;a=commit;h=25239266d554a0442eb676044f03de9d43364c4211:21
JoseStefanI can't boot feisty, because of jmicron bug, Is there anyway to dump the boot text on to a usbkey, while i'm at the "busy box"11:21
mjg59So yeah, it's certainly been reverted11:21
mjg59JoseStefan: Wait for the next daily11:21
benhI suppose I really need to get a 0.1 of my ps3 gfx bootloader out11:22
benhso you guys can get some nice icons in your config file to show up on it :-)11:22
crimsunmjg59: let me know if sound works on your mac* now11:22
mjg59crimsun: Oh, good question11:22
crimsun(at your convenience, of course)11:22
benhthere should be no need for separate CDs... unless something is fuckd up with kboot11:22
JoseStefanmjg59, i understand this daily has the kernel that is supposed to fix the problem, so maybe if i could provide more info, it would be useful11:22
=== benh will install & test ubuntu/ps3 today or tomorrow
crimsunJoseStefan: err, -13 just rolled into the archive today, so I'm pretty sure the current daily _doesn't_ have it11:23
PhinnFortwoohoo, ck has it's own wiki now: http://ck.wikia.com/wiki/Main_Page11:23
JoseStefancrimsun, anyway of knowing of what kernel is on the disk, by looking at the disk tree, or opening files on the CD ?11:25
=== benh 's laptop update to feisty almost fully d/l ... cross fingers
crimsunJoseStefan: uname -r  in a shell is sufficient11:26
BenCbenh: No room for otheros.bld and ps3 kernel+initrd on normal ppc CD11:26
JoseStefancrimsun, if it's running, i mean without booting it (live-cd)11:26
benhBenC: wow, it's -that- cramped ?11:26
benhBenC: what kernel do you use ? once it's finally properly merged, it should be a single image for all ppc64 including ps3, but we aren't quite there yet11:27
crimsunJoseStefan: http://cdimage.ubuntu.com/daily/current/source/feisty-src-1.list11:27
crimsunJoseStefan: in fact, according to that, the current daily has it11:27
JoseStefancrimsun, does this apply to daily-live as well?11:29
crimsunJoseStefan: no11:30
=== marcin_ant [n=marcin@194.114.146.126] has joined #ubuntu-kernel
mjg59crimsun: Ok, that's got it, but I needed to manually unmute the "speaker" channel11:30
mjg59(Which wasn't displayed by default)11:30
crimsunnote that http://cdimage.ubuntu.com/daily-live/current/feisty-desktop-i386.list still lists 12.2011:31
crimsun^ JoseStefan 11:31
crimsunmjg59: ok, thanks11:31
JoseStefancrimsun, thanks was looking for a /source subdir :o11:31
mjg59crimsun: That is, I have separate speaker and headphone options, and no master control11:31
crimsunmjg59: is your /proc/asound/card0/codec* in a bug report? [I think it is, but $toomanybugs] 11:32
mjg59crimsun: Eh, not sure11:33
JoseStefancrimsun, ok, now i've learned how to find out what kernel is on a daily-live without going for the surprise element :D11:33
crimsunJoseStefan: if you're really itching for feisty, just use the current daily11:33
mjg59Hm. -13 seems to have lost the ability to reboot my mbp.11:33
benhhrm... they powerpc feisty CDs aren't in the main location... not mirrored :-(11:34
PhinnFortis there any reason not to use noatime in fstab on a normal desktop system?11:34
JoseStefancrimsun, i'm trying to help fix this jmicron issue, since it's been there for a while ;)11:34
crimsunbenh: http://cdimage.ubuntu.com/ports/releases/7.04/beta/11:35

benhcrimsun: yeah, found that, but not mirrored herre... thanks anyway11:35
benh(.au is slow when not mirrored)11:35
mjg59crimsun: Any idea why gnome-volume-applet claims to be altering PCM, but is in fact altering front?11:35
crimsunbenh: http://se.archive.ubuntu.com/mirror/cdimage.ubuntu.com/ports/releases/7.04/beta/11:36

benhwell. ... let me dbl check11:36
crimsunmjg59: err, no idea about g-v-a11:36
benhyeah, not there11:37
crimsunI should stop using pA momentarily to check that. Will see what I can whip up tonight.11:37
