**** BEGIN LOGGING AT Fri Mar 09 02:59:58 2012 Mar 09 05:05:26 im trying to install the omap3 sgx drivers on 12.04, here is the output http://paste.ubuntu.com/875606/ Mar 09 05:05:43 obsoleted or only available from another source? Mar 09 09:48:58 * micahg hugs janimo`, maybe we'll get chromium and ghc on armhf on the ssame day Mar 09 09:49:31 would be nice. But until I see them both successfully built I am not celebrating :) Mar 09 09:49:56 * janimo` hugs micahg back Mar 09 10:57:55 i guess it's not normal that to get the 'correct' resolution on a pandaboard with a hdmi -> dvi cable you need to boot it with the cable connected to the panda's dvi socket and then switch over to hdmi to get the actual picture Mar 09 10:58:37 if i boot with it connected to the panda's hdmi socket then i get a 'squashed' image Mar 09 11:09:04 and why is it just shutting off after a few minutes? Mar 09 11:24:45 brendand, how do you power the board ? Mar 09 11:25:09 should at least be a 3A (better 4A) 5V supply Mar 09 11:25:37 ogra_, 5v straight to the wall Mar 09 11:25:47 ogra_, has always been working fine Mar 09 11:26:18 maybe it's too much? should i switch back to usb power from my laptop? Mar 09 11:26:29 that doesnt mean much if power consumption changed due to driver changes :) Mar 09 11:26:33 brendand: do your monitor support "p" resolutions? Mar 09 11:26:49 brendand: it might be that your monitor only support interlaced resolutions Mar 09 11:26:49 xranby, meaning? Mar 09 11:26:53 how many amps does your PSU have ? Mar 09 11:27:38 ogra_, well, it's still a USB cable, but it goes into a wall socket Mar 09 11:27:41 brendand: which of these resolutions do your monitor support? 720p, 1080i, or 1080p Mar 09 11:29:16 xranby, none of those? Mar 09 11:29:41 according to xrandr on my laptop Mar 09 11:29:54 but that's probably not true Mar 09 11:29:57 then the squashed image might be normal, depending on what exactly the EDID of the monitor supplies to the driver Mar 09 11:30:03 that's just the vga outputs Mar 09 11:30:07 and if the driver can support that Mar 09 11:30:21 ogra_, oh, the squashed image is secondary - i can get over that Mar 09 11:30:31 ogra_, it's the power off that's bothering me Mar 09 11:30:46 well, you should find out how many amps your PSu actually offers to the board Mar 09 11:30:47 happens a minute or so after login Mar 09 11:31:05 below 3A you will get probs if you have any USB devices attached Mar 09 11:31:27 usually a non Y USb cable doesnt provide enough Mar 09 11:31:30 ogra_, i don't have an ammeter unfortunately Mar 09 11:32:08 (i think its 500-750mA per USB line ... Mar 09 11:32:09 ) Mar 09 11:33:02 ogra_, the wall plug is definitely 5v Mar 09 11:33:20 sure, else you wouldnt be able to plug USB directly into it Mar 09 11:33:38 but whats important is the power Mar 09 11:34:02 if you power the panda through plain USB i wouldnt even bother to try running any desktop image on it Mar 09 11:34:16 and even headless will get issues once the kernel powered up all devices Mar 09 11:39:26 ogra_, so here's the full deal. i have a usb cable with one end USB and one end 5v connector Mar 09 11:39:42 ogra_, i also have a wall adapter from a kindle Mar 09 11:39:48 ogra_, which is 5v Mar 09 11:40:02 the voltage is ireelevant Mar 09 11:40:18 ogra_, so i have two options, one is to plug the usb cable into my laptop, the other to plug it into the wall adapter Mar 09 11:40:30 ogra_, if i plug it into the laptop it stays on Mar 09 11:40:42 ogra_, if i plug it into the wall adapter it powers off Mar 09 11:41:15 so i have got my workarounds now, but things have definitely changed Mar 09 11:41:33 right, both will not provide enough power, one just stays a bit more stable Mar 09 11:41:46 seriously, get a proper PSU Mar 09 11:42:18 powering through USB will have unpredictable sideefects and you wont be able if the issues you see have to do with SW or power Mar 09 11:42:33 a single USB cable *cant* provide enough power for a panda Mar 09 11:43:37 s/abel/able to tell/ Mar 09 11:46:20 ogra_, you're probably going to smack me down for this, but it is possible the cable itself is not a USB cable but just has a USB connector on one end? Mar 09 11:48:29 unlikely Mar 09 11:48:34 although you've made it quite clear that the optimal setup is to have a proper 5v PSU, with no hint of usb-ness about it Mar 09 11:49:26 you can run the board headless with an Y-USB cable, that will just provide enough power to run a headless system without any attached USB devices Mar 09 11:50:03 if you run a desktop and use a USB kbd and mouse as well as the builtin USB NIC, you *need* more than 2A Mar 09 11:51:31 ogra_, ok, so this is the cusp of the problem. you'll be shocked to know i don't have much electrical training Mar 09 11:51:47 so the wall plug is actually only 0.35 Amps Mar 09 11:51:50 you dont need any electric training Mar 09 11:52:05 just make sure your HW fulfills the needed specs Mar 09 11:52:19 ok, i'll rephrase it. i haven't a f*ing clue Mar 09 11:53:00 let me give you a clue then: buy a >2A 5V power supply Mar 09 11:53:31 (and note they are expensive, unlikely you get one for less than $15-20) Mar 09 11:54:25 even your way to power from the laptop wont gain you a stable platform Mar 09 11:54:42 (even though it doesnt shut off immediately) Mar 09 11:54:50 no, but for now it's working (mostly) until i get a proper PSU Mar 09 11:55:08 which i will Mar 09 11:55:13 ringht, just dont ask about bugs until you have stable HW Mar 09 11:55:45 since the low power makes it totally unpredictable if there is actually a SW bug Mar 09 11:56:06 i wasn't aware of the required ampage, so now i know what might cause any strangeness Mar 09 11:56:18 right :) Mar 09 12:03:29 zyga, I ran the built from sources kernel on imx53 finally Mar 09 12:04:19 sledges, and? Mar 09 12:04:36 s/ran/successfully ran/ :) Mar 09 12:04:46 you need to use identical toolchain Mar 09 12:04:52 to that of the working binary Mar 09 12:06:01 there's also a patch to work with gcc4.6.2 (failed in my research so far, but there are still things to try), 1 moment... Mar 09 12:06:30 https://build.pub.meego.com/package/view_file?file=000-kcflag-mno-unaligned-access.patch&package=kernel-adaptation-n900&project=CE%3AAdaptation%3AN900&rev=9cdc38022e14fe78051a2e799587a375 Mar 09 12:15:36 hmm why are this patch not part of the ti omap4 kernel tree? http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7178/1 Mar 09 12:17:19 sledges, does sata work for you? Mar 09 12:17:31 yes Mar 09 12:17:55 sledges, I suspect my board is simply broken Mar 09 12:18:00 not soldered right or something Mar 09 12:18:35 I had sata working fine with that kernel - did you try that kernel?: http://cdimage.ubuntu.com/releases/oneiric/release/ubuntu-11.10-preinstalled-desktop-armel+mx5.img.gz Mar 09 12:19:15 break in uboot and override bootargs with rootfs-on-sata Mar 09 12:21:27 i tried other ~5 kernels from different sources (linaro, ltib, 2.6.35/38), none of them worked (or halting after decompress or not enumerating SATA) Mar 09 12:21:42 so don't give up :) and give it a last shot, zyga Mar 09 12:22:03 sledges, I cannot try right now, that device is production Mar 09 12:22:10 sledges, I'd need a new IMX from linaro Mar 09 12:22:12 this one is personal Mar 09 12:23:12 production? IMX from linaro - you mean HW? I thought Linaro provide only SW BSPs Mar 09 12:23:53 sledges, I mean I'm using this imx to do stuff 24/7 and I cannot tinker with it Mar 09 12:24:05 sledges, linaro as my host/employer so that I can use it for my linaro-work Mar 09 12:24:15 zyga, understood ;) Mar 09 12:24:25 well, good luck and keep in touch! Mar 09 12:24:33 sledges, I need panda es, origen, and imx53 from the last gen lineup Mar 09 12:24:53 wow, smoking! :) Mar 09 12:32:20 jamespage: ping i will try if that patch improves the https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/845158 situation Mar 09 12:32:22 Launchpad bug 845158 in openjdk-6 "Frequent java task hang on ARM server" [Undecided,Confirmed] Mar 09 12:32:49 jamespage: this patch applies cleanly http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7178/1 on the ti omap4 kernel tree Mar 09 12:33:06 i am compiling my own kernel using it Mar 09 12:40:35 any idea if /sys/class/power/battery/current_now is allowed to return a negative value (to show the battery is discharging)? Mar 09 12:41:08 upower seems to apply abs() to it, but other power daemons seem to assume only positive currents Mar 09 12:41:48 I failed to find any documentation about the required values (beside that the field is signed int) Mar 09 15:46:20 I've installed 11.10 on my pandaboard but what I think is gdm isn't letting me log into anything but Unity even though XFCE, fluxbox are listed and supposedly chosen Mar 09 15:46:55 I'm choosing 'Other' on the login screen Mar 09 15:47:11 then I pick say XFCE, login - Unity! Mar 09 15:47:46 Have I go to replace gdm with kdm or another display manager? Mar 09 15:48:22 gdm wasnt used in a while in ubuntu Mar 09 15:48:42 so that might be a gdm specific bug Mar 09 15:49:13 ogra_, I'm just using the default display manager in 11.10 - I was just presuming it was gdm Mar 09 15:49:24 no, thats lightdm Mar 09 15:49:47 ogra_, So this looks like a lightdm bug then Mar 09 15:49:48 and it should just give you the right login (it surely does here) Mar 09 15:50:40 is your ~/.dmrc not writable or some such ? Mar 09 15:51:30 Its writable Mar 09 15:51:50 I've tried logging into Unity 2D, XFCD Mar 09 15:51:59 XFCE and fluxbox with no luck Mar 09 15:52:24 I'm new to lightdm so Mar 09 15:52:36 its not different from gdm in behavior Mar 09 15:52:43 just smaller :) Mar 09 15:53:19 it checks the available sessions, updtaes dmrc and runs the session from there Mar 09 15:53:21 Maybe I can fix it by editing .dmrc? Mar 09 15:54:03 or how do I force it to update .dmrc? It doesn't list all the desktop/wms in there at, Mar 09 15:54:06 atm Mar 09 15:54:17 do both (flux and xfce) have sessions in /usr/share/xsessions ? Mar 09 15:54:41 iirc thats what gdm and lightdem check for nowadays Mar 09 15:55:07 Yeah - I've got 6 files in there now Mar 09 15:55:18 inc ones for XFCE and Flux Mar 09 15:55:54 check if they have proper Exec lines Mar 09 15:56:09 and if tehse executables actually exist Mar 09 15:57:13 you can edit dmrc if you want Mar 09 15:57:48 Session= needs the name of the .desktop file in /usr/share/xsessions you want to use i think Mar 09 18:09:42 hey guys, just wondering, how do you test build your ARM packages? Mar 09 18:12:25 like we test build our x86 packages Mar 09 18:16:37 ogra_: pbuilder? But how do you specify you want a ARM pbuilder? Mar 09 18:17:08 I can make x86 and x86_64 pbuilders, and I was trying out qemubuilder last night, but that just refused to work Mar 09 18:17:10 jamespage: ping Mar 09 18:17:16 shadeslayer: We build our packages natively on arm platforms. Mar 09 18:17:20 xranby_ac100, hey! Mar 09 18:17:23 jamespage: hi Mar 09 18:17:31 GrueMaster: right, but what if I don't have one of those? :) Mar 09 18:17:37 janimo`: \o/ chromium on armhf Mar 09 18:17:56 jamespage: i might have found a fix for the server stalls under heavy load Mar 09 18:18:07 shadeslayer, i dont use pbuilder but there are knobs and switches iirc to make it run with qemu-arm-static Mar 09 18:18:18 shadeslayer: Not sure what to tell you, other than maybe buy one? They are fairly cheap. Mar 09 18:18:19 xranby_ac100, great! I saw you note earlier - how did that work out? Mar 09 18:19:05 jamespage: from the limited testing i have done so fair... looks promising.. but i need to run more tests to be sure.. i am using a patched kernel for my ac100 here Mar 09 18:19:06 ogra_: there's a qemu-system-arm Mar 09 18:19:27 shadeslayer, you want qe,u-user-static Mar 09 18:19:33 oh Mar 09 18:19:39 jamespage: is there some quick way you can cross compile a kernel using xdeb?? Mar 09 18:19:39 ogra_: what's wrong with the former? Mar 09 18:19:48 that runs a full vm Mar 09 18:20:19 jamespage: i was really hoping to check if you had had any chance to run any tests Mar 09 18:20:22 anywayx, i only know there is an implementation in pbuilder that uses it, i have no idea at all how that works or how you use it Mar 09 18:20:42 oh cool Mar 09 18:20:52 I'll look into it Mar 09 18:21:02 thanks ogra_ Mar 09 18:21:13 welcome :) Mar 09 18:22:26 xranby_ac100: What tests are you running that are causing stalls? I'd like to run them here, as I am working on workload testing on arm server. Mar 09 18:23:13 GrueMaster: my test are to run the jogamp jogl unittests Mar 09 18:23:24 cp 1TB file from mmcblk0p1 to mmcblk1p1 :) Mar 09 18:23:32 GrueMaster: let me give you a link to how to build and run them Mar 09 18:24:23 would probably have been easier if my Transformer had a proper SBK version ... *grumble* Mar 09 18:25:21 That would be great. Mar 09 18:26:14 GrueMaster: http://www.trimslice.com/forum/viewtopic.php?p=1804&sid=f05c252a82821fdd7d3924941c1bfb78#p1804 Mar 09 18:26:48 when gluegen and jogl are build then run sh scripts/make.jogl.all.linux-armv7.sh junit.run Mar 09 18:26:52 to start the unittests Mar 09 18:27:35 when i test on my pandaboard running oneiric i can trigger a stall within 10min Mar 09 18:28:07 a stall means that the process gets stuck in some kernel lock and ps ax also stall when trying to list processes Mar 09 18:28:38 GrueMaster: my panda dmesg looks like this http://paste.ubuntu.com/875835/ Mar 09 18:29:08 what i hope are that this patch http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=7178/1 Mar 09 18:29:46 might fix it.. both the ti omap kernel trees and the ac100 kernel tree are missing this patch Mar 09 18:29:58 its merged into linus git tree upstream Mar 09 18:30:52 Interesting. Do we have a bug against the kernel for this? it should be possible to get it in for precise kernel. Mar 09 18:31:00 (if it isn't there already). Mar 09 18:32:24 xranby_ac100, I can run some tests that load up things quite well - yes Mar 09 18:34:48 GrueMaster: we have an old bug not yet pinned to the kernel https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/845158 Mar 09 18:34:49 Launchpad bug 845158 in openjdk-6 "Frequent java task hang on ARM server" [Undecided,Confirmed] Mar 09 18:35:07 GrueMaster: i have been looking high and low for a better testcase Mar 09 18:35:07 * prpplague grumbles about how buggy his ubuntu desktop has been since it has been updated Mar 09 18:38:29 GrueMaster: this issue poped up adain frequently when i was testing the opengl-es bindings with the jogamp community Mar 09 18:38:55 the best test i have are to run the jogamp unittests on a panda Mar 09 18:39:06 you can also pick one test and run it 100 times in a row Mar 09 18:39:07 xranby_ac100: Looking at our 3.2 kernel git tree, I am not seeing this patch applied. Oddly, the link says it is in 3.2-rc3 (unless it is the x86 version of the patch only). Mar 09 18:39:40 GrueMaster: when i checked today its not applied in any ofthe panda 3.1 and 3.2 tree Mar 09 18:39:41 s Mar 09 18:40:24 I'm always looking for new and interesting tests I can automate. I'll see if I can get this test scripted and automated. I'll also file a kernel bug for this patch.

Mar 09 19:51:00 GrueMaster: thanks a lot, poke me if you for some reason fail to build jogamp Mar 09 19:54:07 Will do. Mar 09 20:30:51 syntax error: unknown user 'puppet' in statoverride file Mar 09 20:30:57 i always forget what causes this Mar 09 20:31:10 (dpkg) Mar 09 20:33:23 pbuckley: Pretty much exactly as it sounds. Someone's done a dpkg-statoverride to make something owned by "puppet", but the user doesn't exist. Mar 09 20:34:43 probably from the puppetlabs package for puppet.. and apt-get purge didnt clean it Mar 09 20:34:49 how do i fix it? Mar 09 20:35:55 Can't exec "/tmp/lightdm.config.24521": Permission denied at /usr/share/perl/5.14/IPC/Open3.pm line 186. Mar 09 20:35:58 also been seeing this Mar 09 20:36:07 maybe its time i start over from a fresh flash Mar 09 20:36:25 Simplest method would just be to create a puppet user before trying to remove those packages that seem grumpy, and then delete it. Otherwise, you can fix the actual statoverride in question. Mar 09 20:36:36 ah good idea Mar 09 20:38:07 that seemed to fix the override Mar 09 20:38:26 so im assuming that exec issue comes from /tmp being mount noexec Mar 09 20:38:39 which i did because it was complaining about mount -o remount,exec Mar 09 20:39:21 (and at the time /tmp wasn't a seperate mount) Mar 09 20:39:49 We don't support noexec tmp by default. Mar 09 20:40:00 hrmm.. seemed to want it that way at one point Mar 09 20:40:02 (dpkg, as you note above, unpacks various scripts and runs them from tmp) Mar 09 20:40:06 ill set it back Mar 09 20:40:27 There are ways to change that, and have dpkg use other directories, I believe. Mar 09 20:40:51 Well, I suppose you could just run apt/dpkg with a different TMPDIR set. Mar 09 20:41:22 Updating software catalog...this may take a moment.

Mar 09 21:20:16 electroglue: I don't think TI has pushed them up yet. Mar 09 21:22:08 Most of the bits are in their experimental PPA, but it requires the kernel from the oneiric PPA to work, if I recall. Mar 09 21:22:14 electroglue: ^ Mar 09 21:26:13 micahg and ghc too \o/ Mar 09 21:27:15 janimo`: You've had a fruitful week. ;) Mar 09 21:28:34 infinity, yes, in hindsight it could have been a fruitful single day had I paid more attention and panda had not locked up Mar 09 21:28:49 janimo`: Meh, hindsight is like that. Mar 09 21:29:10 janimo`: Did you end up going the "mangle ghc" route, or "make llvm have sane defaults" route? Mar 09 21:29:30 infinity, the sed-patch route. Without the clean rule :D Mar 09 21:29:38 You sick man. Mar 09 21:29:40 since it is temporary :) Mar 09 21:30:18 well. If I had touched m4 code I'd just be sicker now, so it was the right choice Mar 09 21:30:30 m4 isn't that painful Mar 09 21:31:03 Neither is pulling nostril hairs with vise grips, but why try. Mar 09 21:31:25 ... I've done that. Mar 09 21:31:42 * GrueMaster is the lease bit surprised. Mar 09 21:31:49 *least Mar 09 21:32:00 And s/is/isn't/ ? Mar 09 21:32:16 I think Friday afternoon has taken hold of your fingers. ;) Mar 09 21:33:00 Exactly. I hear my neighbor mowing his lawn, and see blue sky outside my basement window. Thoughts lie elsewhere. Mar 09 21:33:26 Swimming in an pool filled with beer? Mar 09 21:42:18 infinity: so using an oneric kernel really means that the packages aren't available for pangolin correct? I'm looking for hardfp and omap4 extras to be available with the kernel provided by pangolin Mar 09 21:42:56 electroglue: Yeah, as far as I know, that's "soon, but not yet". Mar 09 21:43:32 i feel your pain GrueMaster, it is beautiful outside.. blue skys.. i see the ocean outside my window Mar 09 21:43:36 really hard to focus on work Mar 09 22:47:34 stupid question.. what generates /var/run/motd?
