apwbryceh, those people are maddening, can't they keep their branch still for one day ?07:25
brycehapw, I know it seems like we set up these auto builds, we use them twice, and then Intel's off on some new branch07:30
smbmorning07:32
apwbryceh, so this replaces drm-intel-next as we call it07:35
apwsmb, moin07:35
RAOFWhat, there's *another* drm-intel-next?07:36
brycehapw, essentially.  There is still a drm-intel-next branch, but I gather that it's more of a stable snapshot of the drm-intel-next-queue thingee07:36
brycehRAOF, tis the season07:37
apwbryceh, i guess the question i am asking is what do you want it called :)07:37
brycehRAOF, you might have noticed our drm-intel-* mainline builds became stagnant07:37
RAOFI did, in fact.07:37
brycehRAOF, daniel vetter now maintains them, but in some new branches07:38
RAOF:)07:38
brycehapw, what would you think if we just called these as 'drm-intel-experimental' henceforth?  And then just map that to whatever branch-of-the-month Intel is pointing folks to?07:39
apwbryceh, sounds like a plan to me, as they cannot make a common name we'll have to do it for them07:40
ppisatimoin07:40
* smb proposes drm-intel-toad07:40
brycehI expect we'll have to tinker that when they get new maintainers, but hopefully that's not more than once every year or two07:40
apwdrm-intel-ygiagam ?07:40
smbppisati, ciao07:40
smbapw, tml07:40
apwbryceh, ok we have three at the moment:07:41
apwdrm-intel-next: git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel drm-intel-next07:41
apwdrm-next: git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6 drm-next07:42
apwdrm-intel-fixes: git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel drm-intel-fixes07:42
brycehthe second should still be valid07:42
brycehthe other two need changed.  maintenance was handed from ickle over to daniel vetter.  Use the git links from my email.07:43
brycehso, we should have a new drm-intel-next, the existing drm-next, and a new drm-intel-experimental.07:43
brycehtechnically, drm-intel-fixes still exists; it's maintained by keithp now, however I think it's not of very much interest for our purposes.07:44
apwbryceh, so now there are 4 ?07:44
brycehyes07:44
apwbryceh, the list you have sent me has a drm-intel-fixes ?07:44
apwalso with danvet07:45
brycehapw, yeah just ignore that.  drop drm-intel-fixes, add drm-intel-next-queued (as drm-intel-experimental)07:46
apwok07:46
apwbryceh, ok i think they are building now ... we'll know in an hour what it built08:21
brycehapw, excellent thanks08:21
brycehapw, meantime, I've posted a handful of gpu lockup reports that have mainline kernel patches pointed out as fixes08:22
apwbryceh, remind me of that tag agin08:22
brycehapw, bugs are tagged 'kernel-handoff-graphics', and should show up on the report at http://reports.qa.ubuntu.com/reports/kernel-bugs/reports/_kernel_graphics_bugs_.html, but they're not there yet08:23
brycehapw, they'll all be titled like "GPU lockup blah IPEHR: 0x7....."08:23
brycehI spot checked half of them and the patches seem to be upstream in linus' tree so hopefully should be ripe for picking.08:24
apwbryceh, can we not just stop supporting sandybridge it cannot need any more patches, really it can't :)08:25
brycehtrue, it's getting long in the teeth, we might be able to just declare it obsolete08:27
brycehI wish they showed their work for going from the i915_error_state to a given patch.  But at least they're responding quickly.08:33
ohsixyou can ask them :]08:34
ohsix#intel-gfx08:34
ohsixbut basically it's in the documentation, except when it's not; they find out an opcode that interlocks or something and locks up one of the rings08:35
ohsixand races08:35
apwbryceh, fix for bug #982410 seems to have come down via stable already08:37

brycehapw, hmm, I wondered about that08:38
apwhttp://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-experimental/ <-- bryceh 08:47
brycehyay, thanks apw!08:48
apwsmb, unity ... again ?08:49
smbapw, ?redo from start?08:49
* apw is getting about his 4th unity update of the week, some freeze08:50
smbAh08:50
smbCould it be that this time the glibc/gcc nochange upload caused everything to no-change rebuild?08:51
ohsixfreezes are fiction for superfeatures!08:51
apwits a good job the kernel isn't important08:51
ohsixdid sam ever sort out that whole post .8 being poopy thing08:51
apwohsix, e-no-parse :)08:54
ohsixcompiz .8 -> .9 was horrific08:54
ohsixi still can't look at it or it will crash on me08:54
* apw tries not to notice compiz is running09:14
ohsixi utilize it pretty good, adjusting was tough; there's still some broken stuff, aside from teh crashes09:14
ohsixedge snapping and stuff is broke, some of the plugins don't even work right anymore, windows wobble on focus changes09:15
ohsixthe preference migrator never worked either, had to manually translate the settings, a lot of them were plain gone09:16
ohsixnever worked = "x has encountered a problem", and compiz apoplexy09:18
apwbryceh, ok the ones i can find on this list, there are actually three fixes, one we already have and two others which i have/am producing test kernels for09:37
apwbryceh, ok drm-intel-next has also updated ... so i think they are all working10:07
apwsforshee, bug #934707 seems to be another one of those affected by the backlight changes; i think you had some of those on your plate ?11:16

oratedHello! I tried Canonical/Ubuntu image for running Ubuntu11.10 on Beagleboard B4. The image I used was - http://cdimage.ubuntu.com/releases/11.10/release/ubuntu-11.10-preinstalled-desktop-armel+omap.img.gz - and followed https://wiki.ubuntu.com/ARM/OmapNetbook but I see a blank screen on gtkterm. Is there anything I'm missing?19:07
ppisatiorated: uhm, strange19:07
ppisatiorated: that's an old release19:07
ppisatiorated: what do you see on the terminal screen?19:08
oratedI tried booting the SD card and I could see nothing on gtkterm or any other serial terminal. The ports are configured right19:09
ppisatiorated: then chances are you dd-ed wrong on the sd19:09
ppisatiorated: or the sd has problems19:09

brycehapw, moar gpu lockups.  #982251 looks worth tending on the kernel side.20:07
brycehapw, surprised none of these are showing up still on http://reports.qa.ubuntu.com/reports/kernel-bugs/reports/_kernel_graphics_bugs_.html20:08
ogasawaraOoo, german20:09
ogasawarabryceh: I think apw is probably away at the moment, or at least he should be.  I'll get a test kernel posted.20:10
ogasawarabryceh: I believe jsalisbury mentioned issues with reports on cranberry (running out of space).  likely explains why the report is not getting updated as I think they've been turned off for the time being.20:11
jsalisburybryceh, ogasawara, correct.  cranberry is out of disk space.  I opened an RT ticket a week ago.  The reports on people.canonical.com should still work.20:12

balloonscan someone confirm/deny pae kernel for precise?20:43
balloonsright now it seems I can't install the current daily iso on non-pae hardware.. I thought we kept non-pae support for this cycle20:43
ogasawaraballoons: we kept support, but the installer was changed to default to the pae kernel.  there's a few alternative options... you could use the mini.iso which I believe uses the non-pae kernel by default, also I think Xubuntu does as well.  Or you could install Oneiric and upgrade to Precise.21:04
balloonsogasawara, thanks for the response.. the only discussion I had seen on it was we were keeping support for it21:05
balloonsso I was surprised to find it not working21:05
