asmcos"apt-build world" can compile all arm source code package ?08:56
asmcosCan I re-compile  all soft package ?08:57
persiaYou can certainly recompile everything.08:57
persiaI'm unsure if that syntax is correct for apt-build.08:57
persiaI'm not sure why you'd want to recompile everything though.08:58
asmcosmaybe i want to use a newcompiler ?08:58

asmcosdo you compile ubuntu 10.10 for arm ?09:00
=== lilstevie|ZNC is now known as lilstevie
asmcosdo you have any document about compile ubuntu for arm ?09:01

asmcosuse cross compiler09:07
hrwasmcos: cross compilation of ubuntu packages is not working for lot of packages09:07
asmcosis nothing,i need part packages09:09
asmcosI need know the compilation methods09:10
asmcoshow many do ubuntu 10.10 have packages?09:11
asmcosapt-build support cross-compile ?09:14
hrwasmcos: you need to get used to xdeb09:15
asmcoshrw:thank you09:15
persiacross-compilation *can't* work for lots of the packages.09:16
persiaAnd the number of packages that will fail to cross-compile only increases as people implement more built-time test suites (which we consider best practice)09:16
asmcosoh09:19
persiaNote that everything there now is native-compiled.09:19
asmcoscompile ubuntu on arm ?09:19
persiaFrom what I understand, nobody has ever done large-scale extensive testing to ensure it is safe to mix native- and cross- compiled code.09:20
persiaYep.09:20
vstehleHi ogra, I saw you released images for the AC100 (http://ac100.gudinna.com/); nice!09:33
ograyep09:34
ograwell09:34
ograkind of "images" :)09:34
persiaAnd a personal release, really :)09:34
ograits just a hacked up rootfs :)09:34
ograyeah, spare time fun09:34
vstehleThe kernel is at http://gitorious.org/ac100; how comes you don't have a branch in maverick kernel already ? :)09:35
persiamaverick is frozen.09:35
vstehlepersia: Oh, right, I forgot.09:35
persiaFor natty, needs someone to maintain it.09:35
vstehleOn another topic, I found an interesting "side effect" of the netbook edition; bug #66100309:36
ubot2Launchpad bug 661003 in software-center (Ubuntu) "Debconf dialogs are hidden (affects: 1) (heat: 10)" [Undecided,New] https://launchpad.net/bugs/66100309:36
vstehleNot very "user friendly" :)09:37
persiavstehle, What priority did you set the debconf prompts?09:37
vstehlepersia: No idea; I'll check.09:37
ograright, they neew to be high or critical to be shown iirc09:38
ogravstehle, the kernel is 2.6.29 ... we wont pull that into the distro :)09:38
persiaI hope not!09:38
ogranor will there ever be "real" images unless someone pays or the community steps up to get them (but in a more proper way than "untar that to your SD")09:39
persiaMostly just needs one or two folk.  A kernel maintainer and someone to do image verification.09:40
persiaMind you, getting hosting on cdimage is a bit more opaque and complicated, but in theory.09:40
ograwell, first of all it would need a way to wrtie the kernel updates to the device somewhere :)09:41
persiaOne can't do that even after booting a proper kernel?09:41
bercohi there09:41
ogranope09:41
bercotrying to test #637947 SRU09:41
ograyou cant access the boot bits on the emmc09:41
ograberco, a bit premature :)09:42
hrwogra: use kexecboot09:42
ograberco, the kernel was just accepted a few minuted ago ... and alsa-utils wasnt yet09:42
bercoogra: I just received the notification, thought I could test :)09:42
ogragive it time to build ;)09:42
hrwogra: you put kexecboot kernel in flash, it boots, search on sd/flash for distro kernel and kexecs it09:42
bercoso that's normal I get maverick-proposed not found09:42
ograhrw, if kexec works, yeah09:42
hrwogra: Zaurus guys do that for quite long time09:43
bercoin sources.list?09:43
ograhrw, we had a spec for that to replace u-boot about three releases ago09:43
ograberco, yes, you need to enable it deliberately, -proposed is for update testing09:43
ograberco, packages go to proposed first, only if they recieved enough testing they go to -updates09:44
persiaIt's been 90% done for a couple releases as well, just nobody ever really wanted it enough to finish it.09:44
ograits kind of a staging archive09:44
ograugh09:47
bercoogra: but does it exist yet? I get 404 not found on it09:47
persiaProbably not built yet.09:47
ograso i was testing the sound fix for the last half hour ... suddenly hearing nothing anymore since i started today09:47
persiaAnd you discovered that your headphones were unplugged?09:48
ogra.... and i just noticed my headset is plugged into my laptop09:48
ograyeah09:48
bercolol09:48
ograhaving team calls at night is NOT helpful !09:48
persiaHeh.  +1 for the "is it plugged in" method of troubleshooting :)09:48
ograok, works all fine09:48
* ogra calms down again09:48
bercoogra: persia: thanks, that's good news09:48
ogranow that really woke me up at least09:49
ograberco, we're still missing one part09:49
bercoogra: what do you need?09:49
ograthe pulseaudio profile file isnt there yet09:49
ograso currently HDMI isnt exposed in the UI09:50
bercohas abduenas sent you anything?09:50
ogranot yet09:50
vstehlepersia, I checked the debian/preinst of the concerned package, and all the 'db_input' I see there have a "critical" priority. Also, the window is presented, only it appears in the background, so I don't think this is related to the prio after all.09:50
* ogra checks the longish mail thread again ... i probably missed it09:50
bercoogra: how can I take your changes to test on my side?09:50
bercoI have abduenas file, I could probably share this with you too09:51
persiavstehle, Indeed, it's not.  I think it's related to maxiumus or whatever replaced it.09:51
ograberco, you would need to compile alsa-utils and the kernel from the source package ... better just wait09:51
persiaogra, You understand these WM oddities better than I: any ideas?09:51
hrwogra: switch to using BT headsets for calls09:51
ograpersia, might be a timestamp issue09:51
vstehleogra, persia, you know, the message actually _is_ presented. Its window is just "below" the software center, I think...09:52
ograpersia, i havent done much with WMs for the last 1.5 years but i think metacity introduced a timestamp thing, would probably be a question for mvo if sw-center has "always on top" set or some such09:52
ograthat might override the timestamp09:53
ogravstehle, in any case file a bug against sw-center09:53
persiaogra, timestamp? for wnck-placement stuff?  (and I haven't done anything with WMs in >15 years, so you're closer)09:53
ogra(mvo might reassign it to debconf-gkt or so)09:53
ogra*gtk09:53
persia661003 is definitely the right bug.09:53
persiaBut yeah, probably needs mvo.09:53
ograah, alsready there09:53
vstehleogra, yes09:54
ograbug 66100309:54
ubot2Launchpad bug 661003 in software-center (Ubuntu) "Debconf dialogs are hidden (affects: 1) (heat: 10)" [Undecided,New] https://launchpad.net/bugs/66100309:54
ograheh, you're to fast vstehle :)09:54
vstehleogra, the only problem with this is that it is "user unfriendly" :)09:54
persiavstehle, That's a bug :)09:54
ograyes, agreed09:54
ograhmpf09:57
bercoogra: persia: just updated #637947 with proposed profile09:58
ogramy alsa-utils fix can need some improvement09:58
bercocan you test if HDMI works?09:58
ogradamned09:58
ograno biggie, but alsactl init is only actually needed if no state file exists (it does no harm if its run when it exists but is a useless extra call)09:59
persiaSo it's only needed the first time?10:00
ograyes10:00
ograi'll update the fix with a check for the state file i think10:01
ograi mean i could as well leave it in ... the mixer volumes are properly restored etc10:01
ograbut its not "clean"10:01
ograberco, your pulseaudio.rules wont work10:18
bercowhat's wrong with this file? I just uploaded the file from our audio team10:44
ograberco, it will only work on blaze ;)10:47
bercoogra: agree.11:23
bercois that possible to "or" in the ATTRS{id} field of the rules file? I guess the conf file can apply to both blaze and panda boards11:25
devilhornsogra, !! (just felt like shouting your name) :P11:28
ogradevilhorns, !!!11:28
devilhornshehehe11:29
ograberco, either that or switch inside the conf and use something else in rules11:30
ograi'll have to inspect that11:30
ograberco, once the basics are in i'll look at pulse (unless someone beats me to it)11:32

persiaThe "hello" package is the classic example.14:31

GrueMasterMore of what can be done in the kernel drivers to improve userspace interaction.21:26
GrueMasterHave you gotten any detailed info on UCM?21:26
mpoirierMy quest was related to how the ABE, PDM and FE worked together - I did not looked into UCM specifically21:28
mpoirierI got my information on the former.21:28
mpoirierI'm still thinking about the "to improve userspace interaction"...21:29
rsalvetindec: yeah, saw that bug while at ti21:29
mpoirierGrueMaster: I don't see how that interaction could be improve - the current implementation is the ultimate in terms of flexibilty.21:31
mpoirierGrueMaster: unless you have ideas.21:31
rsalvetindec: awesome, trailers.apple.com works nicely :-)21:35
ndecrsalveti: eheh... and the cool thing is the CPU load ;-)21:37
rsalvetiyeah, around 15%21:37
mpoirierGrueMaster: I think we could fix our other omap3 boards using the same solution that was implemented to fix panda.  After all, the all export a distinct string in /proc/asound/cards.21:54
