**** BEGIN LOGGING AT Tue Aug 09 02:59:56 2011 Aug 09 03:41:25 hello can anyone tell me why ubuntu-omap4-extras-multimedia package fails in ubuntu...I see that two packages have been updated and wont be installed because they no longer exist in the ppa Aug 09 07:36:16 Good After noon friends Aug 09 07:37:42 need some help to enable my beagleboard XM with touch screen Aug 09 07:39:06 it's TSC 2046 Controller Aug 09 07:40:07 and I have "insmod" ads7846.ko (2.6.38-8) Aug 09 07:40:30 but evtest is not responding for touch events Aug 09 08:04:35 any help pls Aug 09 08:36:10 persia, u there? Aug 09 12:01:42 ogra_, you there Aug 09 12:01:54 [ 956.874450] ads7846: disagrees about version of symbol module_layout Aug 09 12:02:07 means wrong driver module right ? Aug 09 12:02:17 yes Aug 09 12:02:44 how did you build it ? Aug 09 12:02:46 am wondering how it's happen, i have build the OS image from rootstock Aug 09 12:03:01 i mean how did you build that module Aug 09 12:03:15 ogra_, it was there bydefault Aug 09 12:03:38 in the rootstock build image Aug 09 12:03:39 cant be :) Aug 09 12:03:46 yes, it is Aug 09 12:03:49 :) Aug 09 12:04:00 there is no kernel in rootstock images by default Aug 09 12:04:07 linux-omap Aug 09 12:04:07 so that cant be Aug 09 12:04:18 unless you forcefully added one Aug 09 12:04:34 i hve added the parameter linux-omap Aug 09 12:05:10 ?? Aug 09 12:05:57 the message above means that your module was compiled differently from the rest of the kernel ... that simply cant happen in a packaged kernel Aug 09 12:06:15 right.. Aug 09 12:06:24 i did seed linux omap Aug 09 12:06:31 so check what kernel packages you have installed Aug 09 12:06:33 while building rootstock Aug 09 12:06:49 ok Aug 09 12:09:23 ogra_, i have build the rootstock with the parameter --seed linux-omap Aug 09 12:09:37 did you check your installation ? Aug 09 12:10:05 yes Aug 09 12:10:31 it seems like everything is fine Aug 09 12:10:43 running on kernel 3.6.38-8 omap Aug 09 12:11:55 locate ads7846 Aug 09 12:12:02 where is that located Aug 09 12:12:15 /lib/modules/kernel/--- Aug 09 12:12:26 where exactly Aug 09 12:12:37 i dont see it being built in any of our arm kernels Aug 09 12:12:55 ogra@panda:~$ locate ads7846 Aug 09 12:12:55 ogra@panda:~$ Aug 09 12:13:02 /lib/modules/2.6.38-8-omap/kernel/drivers/input/touchscreen Aug 09 12:13:03 definitely not enabled on omap4 Aug 09 12:13:15 very strange Aug 09 12:13:47 oh, i see, on omap4 it is compiled in Aug 09 12:13:53 oh.. Aug 09 12:13:59 but mine is omap3 Aug 09 12:14:02 beagleXm Aug 09 12:14:15 right, i dont have one running here so i cant check Aug 09 12:14:21 ok Aug 09 12:14:38 file a kernel bug then against the linux package (mention omap3 in the description) Aug 09 12:14:45 ok Aug 09 12:15:05 though that still doesnt explain the error Aug 09 12:15:24 and i think only the kernel or touch teams could help here Aug 09 12:15:30 ok Aug 09 12:15:52 or I have to build the kernel here right? Aug 09 12:16:32 you could do that too, indeed, or try one of rcnee's kernels (there is a PPA somewhere with his kernel packages) Aug 09 12:16:57 i have tried but failed to enable SGX driver Aug 09 12:17:13 anyway will give a try again Aug 09 12:17:29 make sure to file bugs if you find issues ;) Aug 09 12:17:36 sure will do Aug 09 14:32:15 nvflash looks fun Aug 09 14:32:25 heh Aug 09 14:32:56 nightmare kind of fun Aug 09 14:33:21 what for do you need it ? Aug 09 14:33:37 ogra_: Hannspree hannspad - cheap android 10.1" tablet Aug 09 14:34:32 ah Aug 09 14:34:46 well, if you have a good kernel you should only have to use nvflash once Aug 09 14:35:10 i.e. a good kernel like the ac100 one wheer you can see the boot partitions from userspace :) Aug 09 14:36:43 problem is that there are no good kernels for it. vendor 'forgot' to give gpl source so kernels from community only and they lack few things Aug 09 14:37:15 did someone report it as gpl violation already ? Aug 09 14:38:04 checking that is on my todolist Aug 09 14:38:34 well, generally the chromeos kernels are a good start for tegra stuff Aug 09 14:41:49 Hi, I can't figure out why https://launchpadlibrarian.net/76889732/buildlog_ubuntu-oneiric-armel.libvirt_0.9.2-4ubuntu8_FAILEDTOBUILD.txt.gz is failing; I don't *think* it's due to my change. Would somebody be able to have a look. Aug 09 14:41:53 ? Aug 09 14:46:32 me looks with no promises that he has more clue Aug 09 14:51:51 wow, looks really bad Aug 09 14:57:06 cjwatson: Is that a python testsuite? Aug 09 14:57:17 cjwatson: If so, I imagine it relates to https://launchpadlibrarian.net/76841318/buildlog_ubuntu-oneiric-armel.python-apt_0.8.0ubuntu3_FAILEDTOBUILD.txt.gz Aug 09 14:57:48 well, doesnt look like anything used libnl3 on arm before Aug 09 15:02:59 infinity: not seeing the link ... Aug 09 15:03:16 (but I don't actually know, I'm entirely new to libvirt and was just trying to get everything shifted over to libnl3) Aug 09 15:03:30 cjwatson, wild guess: the missing classid file gets pulled by a netlink socket, our kernel on the ancient buildd HW misses bits the nl3 lib uses, so the dtd doesnt end up where it should be Aug 09 15:03:49 (really wild guess) Aug 09 15:05:14 Oh, I didn't look closely. I'm barely awake here. :P Aug 09 15:05:25 Brain just saw two testsuites die. :P Aug 09 15:12:28 i dont have a panda with a disk atm, but i can do a testbuild on an ac100 Aug 09 15:12:40 to see if its machine related Aug 09 15:19:43 Hello, i want to test the uart port on the beagleboard xm with a oszilloscope to check the uboot configuration, i have disabled kernel pinmux. i know that uart2 is ttyO1, are there any possibily to send data over this port ? Aug 09 15:49:24 does anyone have any idea why i get inverted colors on my cursor and the xterm text, like this: http://dl.dropbox.com/u/952540/wtf.jpg Aug 09 15:50:09 if i swap to a text console and back to X, then they show up correctly Aug 09 15:50:36 also, there's no text showing up on any of the apps Aug 09 15:50:47 some underscores here and there, but mainly nothing is visible Aug 09 15:57:55 what arch is that ? Aug 09 16:05:44 omap4, custom maverick rootfs, kernel 2.5.35-980-omap4 Aug 09 16:06:56 i have no idea what I've messed up because an earlier rootfs i built didn't have that problem.. Aug 09 16:14:08 well, i guess i'll just rebuild the thing for the millionth time. Aug 09 16:22:00 before that it'd be nice if i could even once get the video decoding hw accelerated, but there's no info about that on the wiki. or anywhere. i mean, there's the installation instructions for omap4-extras and "use totem", but no information about what videosink should be used when using gst-launch etc. or if any other pads are required. Aug 09 16:22:38 it should just work out of the box in maverick Aug 09 16:22:58 oh Aug 09 16:23:04 there are no codecs provided by TI for natty so dont bother to try it there (or bug TI) Aug 09 16:23:25 we should get codecs for oneiric again Aug 09 16:34:55 cjwatson, fyi, thats how the libvirt build fails for me in a oneiric chroot on an ac100 http://paste.ubuntu.com/662055/ Aug 09 16:37:31 fails a lot earlier in test-chown Aug 09 20:45:50 ogra_, openmax codecs from TI?(re your chat with fisuk above) Aug 09 22:08:25 FYI, testing Nathy on Pandaboard, I got I/O errors with a brand new SD card ( Lexar, Class 10, 32GB). I can resize the partition, and at reboot -> nothing. After some investigations, I isolated this issue : http://paste.lisp.org/display/123918 Aug 09 22:09:52 all the other cards I tested work as expected. The second 32GB I tested, has other problems : I got lot of I/O issues at runtime (e.g. compiling a big application), and the fs is remounted in read only mode Aug 09 22:10:50 after some little search, the relevant code in the kernel is located in drivers/mmc/card/block.c Aug 09 22:11:07 at least the error messages (say the what, not the why) Aug 09 22:11:29 anybody aware of 1) existing issues ? 2) existing bug reports around that ? Aug 09 22:12:55 thanks in advance for any help Aug 09 22:12:57 :-) Aug 09 22:17:23 You might just have bad cards. I have no issues here with an LX 32G Class 10. Aug 09 22:17:26 ericb2: you any further in finding the cause? Aug 09 22:29:30 infinity: thanks for the info Aug 09 22:29:55 infinity: could this be another issue type, like the resize does something wrong, or I don't know ? Aug 09 22:30:23 infinity: the problem is, I got other issues with the same disk image Aug 09 22:31:01 infinity: like file system suddenly in read only mode, every time the machine has a good load or something similar Aug 09 22:31:03 ericb2: i tried with a manually resized image, that was good. its not resize thats causing the problem Aug 09 22:31:40 MrCurious_: thanks Aug 09 22:31:54 np Aug 09 22:32:08 MrCurious_: you avoided me to try myself :) Aug 09 22:32:48 * ericb2 scratching his head Aug 09 22:36:21 MrCurious_: so we are two with problematic cards, both class 10 and high speed (at least this is written on the package) Aug 09 22:37:12 other possibility could be a wrong high speed card, e.g. identified with high speed parameters and that's not true, causing timeout and worse Aug 09 22:40:37 davidm: so it's now official that the scheduler is the culprit? Aug 09 22:41:41 TheSeven, it's official it's a general ARM issue, not a Panda USB issue Aug 09 22:42:01 likely scheduler but not completely sure about that Aug 09 22:42:16 Was best rename I could come up with that fit what we are seeing Aug 09 22:42:24 ope to suggestions for a better name Aug 09 22:42:58 it would be interesting if this is only related to USB, I/O in general, or even every kind of thread execution Aug 09 22:44:23 TheSeven: It's not just USB, and probably not just I/O. It really looks like it's spinlocking breakage. I'm assured that people smarter than me are looking deeper. Aug 09 22:44:32 IT also makes a difference on writing to the SD card Aug 09 22:44:56 my guess is it has hard coded timings that just work with slow cards, rather than detecting card state, allowing for it to run at max speed Aug 09 22:45:06 or a hard coded wait that isnt needed with faster cards Aug 09 22:45:07 infinity, I'm trying to get as many people as possible looking at it ;-P Aug 09 22:45:11 if i had to "guess" Aug 09 22:46:55 MrCurious_: I use a few class 10 cards (one even the same brand as ericb2) with no issues. Aug 09 22:46:58 davidm: but compared with what's going on with USB storage, the differences on the SD interface were almost neglegible Aug 09 22:47:11 s/with/to/ Aug 09 22:47:20 rev c board? Aug 09 22:47:44 TheSeven: Yes, but SD is slower by default, so sitting in idle loops 75% of the time doesn't hurt as much. :P Aug 09 22:47:46 infinity: I believe you. Just searching how I can proof my reseler it is defective / not good Aug 09 22:47:47 at least my board was rev c Aug 09 22:48:32 infinity: this card is expensive (76 euros), and I'm not happy Aug 09 22:48:39 ericb2: SD cards just aren't intended for compiling things on them Aug 09 22:48:49 TheSeven: he he Aug 09 22:49:05 TheSeven: I'm testing the armhf build on USB stick Aug 09 22:49:38 TheSeven: on USB disk, it works. Trying the usb key now (more easy for traveling) Aug 09 22:50:23 ericb2: usb is currently buggy, and possibly 10x slower than it should be Aug 09 22:50:34 MrCurious_: promising ^^ Aug 09 22:51:09 MrCurious_: I was wondering whether an sata support will arrive some day Aug 09 22:51:16 would be fantastic Aug 09 22:51:34 sata is reliable, really Aug 09 22:52:00 Doubtful on panda. Maybe omap5? Aug 09 22:52:51 GrueMaster: indeed, it will probably not occur with Panda . Crossing the fingers Aug 09 22:53:09 for omap5 .. in one, two years ? Aug 09 22:53:13 * ericb2 hides Aug 09 22:53:13 Find me a mobile phone that needs SATA... Aug 09 22:53:21 Other than adding it to the USB bus, I wouldn't get your hopes up on panda. Aug 09 22:53:21 (Panda's essentially a phone dev platform) Aug 09 22:53:46 infinity: I meant more a multimedia one ( double hdmi .. ) Aug 09 22:53:47 Panda is the same hardware as the Droid 3. Aug 09 22:54:28 + lot of decoders inside. Looks lke a mix of best technos, for hackers and like Aug 09 22:54:53 Other than a few NAS systems out there, I don't know of any mainstream arm based products that also have sata. Aug 09 22:55:08 There are tons. Aug 09 22:55:17 Mostly set-top boxes, PVRs and the like. Aug 09 22:55:23 Mainstream? Aug 09 22:55:34 Well, depends on how you define "mainstream". Aug 09 22:55:38 MrCurious_, ericb2: USB is still way faster than SD Aug 09 22:55:39 maybe nfs, as I told previously Aug 09 22:55:44 Most of those are PPC based afaik. Aug 09 22:55:52 Most people get them bundled with cable service and such, but that's pretty "mainstram", you just don't go comparison shopping. Aug 09 22:56:25 * GrueMaster owned a tivo and owns an HD DVR. Aug 09 22:56:27 * ericb2 got a powerbook in the room. bought in october 2005 or so Aug 09 22:57:11 works well Aug 09 22:57:23 davidm: So it doesn't make sense to do further random testing and throwing results at the bug from my side? Aug 09 22:57:31 * davidm still owns 2 working tivo series I and has 4 for spare parts Aug 09 22:58:07 oops, it's late, and I need to sleep a bit Aug 09 22:58:08 Any valid testing might help, the bug is not isolated as yet Aug 09 22:58:15 good night all Aug 09 22:58:35 Apparently the PVR in my house is MIPS. Aug 09 22:58:40 OK I'm off, I'll look at the back scroll later Aug 09 22:58:57 infinity: got a gdium too :) Aug 09 22:59:52 * ericb2 gone for true Aug 09 23:03:37 theseven: i use a ssd on usb, it makes ubuntu on panda tolerable :D Aug 09 23:05:19 MrCurious_: Try booting with nosmp and checking your IO performance. Aug 09 23:09:28 MrCurious_: a thumbdrive would do as well Aug 09 23:18:08 yeah Aug 09 23:18:21 gruemaster: is that a opt for boot.scr? Aug 09 23:18:38 Yes. Add to the kernel cmdline. Aug 09 23:19:05 is that going to kick the speed up? Aug 09 23:19:10 but at a cost Aug 09 23:19:32 IO speed should be 3-4x but no SMP. Aug 09 23:19:52 thats a strange tradeoff Aug 09 23:19:57 counterintuitive Aug 09 23:20:03 See above about spinlocks. Aug 09 23:24:01 doubt spinlocks are broken, more like not optimized **** ENDING LOGGING AT Wed Aug 10 02:59:57 2011
