brycetjaalton: whoa, you've been busy!!18:47
brycetjaalton: calc says he's getting a backtrace when enabling xinerama with nvidia which he didn't have pre-break - was there an upload of -nv or lgm recently?18:54
tjaaltonbryce: lgm? you mean lrm? I've prepared a new lrm with new nvidia & ati, but haven't uploaded it19:34
tjaaltonthere is a bug report about xinerama & nvidia crashing on gutsy, and today someone reported that against hardy19:36
bryceyeah sorry lrm19:39
bryceah, bet that's it19:39
bryceI've asked calc to file a bug, I'll let you know when he tells me the bug id#19:40
bryceI also notice there's a new -ati 6.7.197-1?19:40
tjaaltonand a sync request, yes19:41

tjaaltonthat's the hardy version19:42
* bryce passes along19:44
brycehmm, however the backtrace calc posted looks different19:44

bryce that was the backtrace it gives when enabling xinerama19:44
tjaaltonok19:46
tjaaltonhum, ice cream :) ->19:46
tjaalton(and Heroes.. S01E10 or so :P )19:47
brycetjaalton: did you see the dec22 comment here about fglrx incompatibiltiy on hardy?  http://lwn.net/Articles/263048/#Comments20:16
bryceI'm assuming that one's fixed already (not enough info to say)20:17
Q-FUNKre20:32
Q-FUNKbryce: hiya!  it seems that what makes DDC fail with -amd is some new x86 emulator code that crept in since X core 1.320:32
bryceheya Q-FUNK20:33
Q-FUNKbryce: various people have been investigating this and noticed some weir redundant bits in the X core code.20:33
brycewhat needs to be done to fix it?20:34
Q-FUNKI'm starting to guess that more and more functionalities that were previously implemented in each driver are slowly being meatballed into more generic features and moved to X core.20:34
brycesounds likely20:34
Q-FUNKsome BIOS apparently don't like being tempered with twice when polling VBE registers20:35
Q-FUNKthis is what's been causing the freezes that -amd users on platforms that use General Software BIOS have been experimenting.20:35
Q-FUNKthe driver probably need to have large parts of it #ifdef'ed to skip them and #include newer X core features instead.20:36
Q-FUNKthen again, since this used to work mostly OK until Edgy (X core 1.2), there could be some nasty bugs in that new generic x86 emulator inside X core.20:37
Q-FUNKbartman has been working on narrowing it down.  there's been a new geode list created on x.org that is very active lately, with several players involved in tracking and fixing this.20:39
brycewho will be trying out #ifdeffing stuff?20:39
Q-FUNKbartman20:39
bryceah, bartman?20:39
Q-FUNKa kernel developer20:40
brycegood to hear about the activity20:40
bryceis that bart massey?20:40
Q-FUNKhe's dabbling into X code simply because he has extensive knowledge of things like polling into BIOS registers20:40
Q-FUNKBart Trojanowksi20:40
jcristaucouldn't it be caused by using x86emu in 1.3 instead of vm86 in 1.2?20:40
Q-FUNKhttp://www.x.org/wiki/AMDGeodeDriver20:41
brycedo you need my help with anything in particular with it?  I've been keeping an eye on things from the sidelines but don't know much about driver internals so haven't had much input to share20:41
Q-FUNKjcristau: that is the current suspicion, yes20:41
Q-FUNKx86emu sems at cause20:41
jcristaunot related to new code then20:42
Q-FUNKhttp://lists.x.org/mailman/listinfo/xorg-driver-geode20:42
Q-FUNKx86emu was already there in 1.2, but not used?20:42
Q-FUNKhere, the same -amd source code compiles and runs flawlessly against X 1.1, then bugs like unability to use ctrl+alt+Fx to change console creep in in X 1.2, even though it works mostly OK.20:43
Q-FUNKby the time we try to build against 1.3, several competing hardware manufacturers reported complete system freeze20:44
jcristauQ-FUNK: x86emu has been there forever20:45
Q-FUNKbryce: we're mostly trying to figure out what x86emu is trying to do that freeze the system on some BIOS20:45
jcristaujust unused by default on x86_3220:45
Q-FUNKah. ok20:46
brycetjaalton: seems the ati logo issue is back20:47
bryce<brian> bryyce: I installed the fglrx driver and I have some weird watermark on my desktop say "AMD Testing use only Unsupported hardware"20:47
bryce<bryyce> brian, was this the version from ubuntu, or downloaded from the ati site?20:47
bryce<brian> bryyce: I used restricted-manager to install it so the Ubuntu version20:47
Q-FUNKI wonder what x86emu does that make -siliconmotion and -amd fail with X 1.320:47
Q-FUNKjcristau: any particular reason for emulating x86 on real x86 hardware instead of keeping with vm86?20:50
jcristauQ-FUNK: it works on x86_64 kernels. vm86 doesn't.20:51
jcristauplus, it makes it more likely that x86emu bugs get fixed, which benefits all archs20:51
Q-FUNKtrue, but it leaves users in the dust until this is fixed.20:51
Q-FUNKfor all we know, -amd bugs are caused by x86emu and our -amd code is fine.20:52
jcristauthat's certainly possible20:53
tjaaltonbryce: well, the current lrm has fglrx 7.11 (aka 8.43), which is newer than the previous 8.42. maybe it's just a problem with 2.6.24 instead22:07
tjaaltonand I don't remember doing anything about the logo :)22:08
ubotuNew bug: #177829 in linux-restricted-modules-2.6.24 (restricted) "Please update fgrlx to 8.44 aka 7.12" [Undecided,New] https://launchpad.net/bugs/17782922:55
tjaaltonbryce: I'll upload a new lrm with latest stable nvidia tomorrow. no fglrx update since it seems to have some known issues (as always)23:41
bryceok23:42
brycetjaalton: http://people.ubuntu.com/~bryce/plots-0.1.html23:50
brycebeen hacking this together today23:50
tjaaltoncool, please add xorg-server too :)23:51
bryceunfortunately xorg-server data hasn't been collected (http://people.ubuntu.com/~brian/complete-graphs/)23:52
tjaaltonoh right23:52
brycethere is also displayconfig-gtk, but graphs for them haven't been generated23:52
tjaaltonan now that it has less than 70 bugs..23:52
bryceI'll bug brian about it later23:52
tjaaltonI cleaned xorg&xorg-server bugs from crashers that seemed to be driver specific, so that's why -ati/-intel/lrm bug counts have soared :/23:53
tjaaltonand -nv, obviously23:54
tjaaltonthe launchpad janitor seems to be offline, btw23:54
tjaaltonthere would be 2000 closed bugreports if it ran today23:55
bryceahh, I wondered about that23:55
bryceI think I read in the last lp update that the janitor was showing what *would* expire, but wasn't actually doing the expiration23:56
bryceI gather they want to implement code to allow projects to opt-in to the expiration stuff23:56
tjaaltonI guess that's a no-brainer for ubuntu at least..23:57
