iloldHi. can you patch, meego hardware adaption kernel for n900 on gitorious?14:29
Stskeepsdepends on what, but yes14:30
iloldseems like the IO-Errors yesterday are described here http://talk.maemo.org/showthread.php?t=7278914:30
Stskeepsyou have i/o errors?14:31
Stskeepswhat SD card type?14:31
iloldyes, I was the one with wierd problems, testing 15.12 image.14:32
iloldclass 414:32
ilold*yesterday14:32
iloldthe dto patch desribed in thread was also adapted by openpandora and beagleboard. seems well tested, without problems so far.14:33
kimjuimho, the patch in that thread is just wrong. hack to get broken card "working"14:34
ShadowJKwhat's the solution when half the market is broken cards14:35
kimjuit hardcodes the timing register, instead of using card provided values14:35
* ShadowJK thought card provided ones were wrong for most Kingston cards?14:36
kimjuhas that patch been submitted to mainstream via linux-omap? what was the response there?14:37
kimjupersonally I've given up trying to use anything else than sandisk cards.14:38
iloldI think, I read something in august (linux-omap)14:38
iloldbut not sure14:39
iloldother links: http://boards.openpandora.org/index.php?/topic/1592-sd-card-instability/14:39
iloldhttp://patchwork.openembedded.org/patch/9519/14:40
*** alien_ has quit IRC14:40
ShadowJKsandisk is probably the only one that's strictly SD compliant14:41
Stskeepsilold: what card vendor?14:43
iloldsony14:43
*** alien_ has joined #nemomobile14:45
iloldhttp://s14.directupload.net/images/111217/xnl7e72u.jpg14:49
Stskeepsok, and you have proven the sd card isn't simply bad?14:50
iloldyes. I tested the card in different cardreader. I also made a complete test with a tool on an old windows pc of me.14:52
Stskeepsok14:52
iloldI link tool, moment.14:52
Stskeepshow about in maemo5?14:52
iloldits german, but has a english option: http://www.heise.de/software/download/h2testw/5053914:53
Stskeepsok14:53
*** xruxa has joined #nemomobile14:54
iloldwell, in maemo I didn't test the card. but seems like powerkernel is patched already.14:55
Stskeepsok, if you could test it without power kernel then we have a better comparison point14:56
iloldsome advice how to test it on maemo. should I simple write card with some stuff und watch log or is there prefered way?14:58
Stskeepsyeah, watching log is always good14:58
Stskeepsbut anyway, on monday if you remind me, i'll do you a kernel with that patch14:58
iloldok, thanks. until monday I will have it tested in meamo, too.14:59

Stskeepsheh, i've never seen that guide before16:45
Stskeepsso -that's- how it's supposed to work16:45
alien_I just updated the wiki page at http://wiki.merproject.org/wiki/Trying_it_out16:45
alien_please someone proof-read it and try to reproduce the steps16:45
alien_I would like to start to hack on some packages, do I need any SDK installed locally or am I supposed to just use the OBS?17:04
alien_or can I use the QtSDK provided by Nokia?17:05

*** berndhs_950 has quit IRC18:53
alien_there are lots of packages complaining about the lack of dbus-launch19:05
alien_irtual const string Maliit::InputContext::DBus::Address::get() const Error spawning command line `dbus-launch --autolaunch=d0da0824966650e35c8a675000000001 --binary-syntax --close-stderr': Failed to execute child process "dbus-launch" (No such file or directory)19:06

alien_Stskeeps: you missed dbus-x11, that contains dbus-launch20:05
alien_you should add it to the kickstart20:05
*** berndhs_950 has quit IRC20:12
alien_but something looks broken in fullscreen mode, at least for some apps20:14
alien_Stskeeps: I figured it out, the compositor needs to be executed this way: "EGL_DRIVER=/usr/lib/egl/egl_gallium.so /usr/bin/mcompositor"20:30
alien_otherwise anything that uses 3D graphics breaks, such as the terminal and the maps application20:31
alien_actually not20:32
*** berndhs has joined #nemomobile20:43
Stskeepsalien_: ah, it works nicely after that?20:49
alien_nope20:52
alien_it just doesn't start the mcompositor, so the maps works20:53
alien_it looks like a compositor issue20:53
Stskeepsinteresting20:53
alien_didn't you notice it in virtualbox?20:53
Stskeepsi wonder why mcompositor doesn't pick it up like qmlviewer -opengl did20:53
Stskeepslemme try20:54
alien_qml stuff works20:54
Stskeepsso it's not a compositor issue?20:54
alien_but apps such as maddeveloper, terminal and maps appear just like a dark screen20:54
Stskeepsit was just a alpha thing anyway, but good to know that there's a reason why it happens like that20:55
alien_then if you swipe at the edge to minimize them, they will appear to have some content in the task switcher20:55
Stskeepsthe idea is to switch mer core in general to default llvmpipe on all platforms and then on those where GLES works, enable their own hardware adaptations20:55
* Stskeeps checks out the ti20:58
Stskeepsp20:58
alien_well, opengl seems to work, at least glxgears shows around 400fps on my laptop20:59
alien_I think just that the mcompositor is broken21:00
Stskeepsodd, still getting black screens with EGL_DRIVER exported21:00
alien_it might not br that21:00
alien_does everything work on the Nokia devices with the same mcompositor?21:01
alien_mcompositor version, I mean21:01
Stskeepsyes21:01
Stskeepsso in your image you have the maps and such working without black screen?21:02
alien_no21:02
alien_only if I kill the mcompositor21:02
Stskeepsok21:03
alien_but then there is no window management available either21:03
alien_so no way to minimize and close apps from outside21:03
Stskeepsso it might be texture from pixmap isn't implemented properly for the gles libraries in llvmpipe21:03
Stskeepsor that we don't use a proper method21:03
alien_I'm not that much into the OpenGL stuff21:04
alien_no idea21:04
Stskeepsyeah, me neither, but i have some hunches on what's wrong21:04
Stskeepslong story short, i'm surprised it works as good as it did in the first place21:04
Stskeepsso looking forward to spending more time on it and cleaning it up21:05
alien_:)21:05
alien_I also tried to install some more mesa stuff but didn't help21:06
Stskeepsyeah21:06
Stskeepsit's a custom image, kinda put together as a proof of concept21:06
Stskeepsit was already beating my expectations by doing 21-25 fps in widgets gallery on a really bad-for-virtualization laptop21:07
alien_I am also impressed by the performance, it consistently gets me around 60-70fps in the widget gallery21:11
Stskeepswow21:12
Stskeepsin a virtual machine or..?21:12
alien_but this is a pretty speedy laptop21:12
*** niqt has joined #nemomobile21:12
alien_yes, in virtualbox21:12
Stskeepsnot bad21:12
Stskeepsgot VT?21:12
alien_ i5-2540M CPU @ 2.60GHz21:13
alien_yes, it has all the goodies21:13
Stskeepsah, so you can utilize multiple cores21:13
Stskeepsi can't, hence the 21-25fps21:13
alien_just a core is assigned to the VM21:13
Stskeepsjust one..?21:14
Stskeepswell that's better than expected then21:14
Stskeepsi'm just happy to have a mobile environment in a virtual machine that doesn't suck at performance :)21:16
alien_indeed, as compared to the Qemu for arm, this is damn fast21:17
Stskeeps:nod:21:17
Stskeepsthat's one thing intel really screwed the pooch on with meego21:17
Stskeepsinsisting to having to use SSSE3 devices21:17
Stskeepscould have made a amazing environment for development21:18
w00twell, meego couldn't really have scaled (hardware-wise) to other platforms though - their build farm was already stretched :)21:18
w00twe have a much easier time in that regard21:18
Stskeepsyeah, but still21:19
alien_ok, now on another topic, how do you guys develop qt apps for Meego? using the ordinary Qt SDK from Nokia?21:21
Stskeepsfor myself, i hand-write them and use pyside, but that's a problem on nemomobile21:22
Stskeepsi'm usually doing low level stuff in the machine room21:22
alien_ok21:22
alien_but would it work, if say I would just write an app using the N9 target in the Nokia SDK?21:23
Stskeepswe're fairly close to it, but yeah21:24
alien_then would put the same sources into the OBS21:24
Stskeepsbut i would use qml components myself if i were you21:24
M4rtinKsame by me: PySide + QML + Qt Components + handwritten21:29
