Sagemorning07:09
Stskeepsmorn sage07:10
Stskeepsok, so what did we conclude yesterday -- systemui failures?07:10
Sagesystemui fails, it is stuck in some loop somewhere and eats all cpu07:11
Stskeepsyes, and that the secure sharing of pixmap may be faulty07:11
Stskeepsi'm brewing on the new prerelease07:12
SageStskeeps: http://pastie.org/3217622 on panda :P07:14
Stskeepshmm :P07:14
Stskeepswell not really surprised07:14
* Sage ponders what that does on wetab07:19
Stskeepsit tests nokia extensions doesn't it07:20
Sageafaik07:20
Sagewell works better on x86 than panda :D07:21
Sagehttp://pastie.org/3217651 wetab07:21
Sagemainly interested that on Panda the compositor is slow as hell and on x86 it works nicely07:22
Stskeepseglinfo on both could be interesting07:23
Sagethe package was again? :)07:23
Stskeepsegl-utils or something07:23
SageWeTab EGL info: http://pastie.org/321765907:24
StskeepsEGL_nok_swap_region? that's surprising07:24
Sagetwo nokia extensions actually07:25
Stskeepsyes07:25
Stskeepswell that explains a lot07:25
Stskeepsmcompositor will work normally on that, but fall back to slow on panda07:26
* Sage look his n950 and looks worried as nothing comes to screen even when powered on07:29
Stskeepscan you grep glEGLImageTargetTexture2DOES /usr/lib/libGLESv2* on panda?07:29
Sageyes, a moment07:33
*** kimitake is now known as kimitake_idle07:33
Sagefor some reason pandaboard isn't getting ssh server up on boot everytime07:33
SageBinary file /usr/lib/libGLESv2.so.1.7.10.0 matches07:34
SageStskeeps: ^07:34
Stskeepsok07:34
Stskeepsi have one last idea, but i need to see eglinfo07:35
Sagesure07:35
SageThe following NEW packages are going to be installed: egl-utils glew libXxf86vm mesa-libGL mesa-libglapi mesa-libGLU07:35
Sagethat is still a bit of a problem07:36
Sagedoesn't override the GLES though07:36
SagePandaBoard EGL Info: http://pastie.org/321768707:37
Stskeepsyeah, hence why we should package our own07:37
Stskeepswtf :P07:37
SageEGL_NV as in NVidia?07:38
Stskeepsthat's sometimes ok07:38
Stskeepshttp://meego.gitorious.org/meegotouch/meegotouch-compositor/blobs/master/src/mtexturefrompixmap_egl.cpp#line4307:39
Stskeepswe can agree it has all those?07:39
Sageyes07:40
* Sage tries to start mcompositor again after a long time 07:41
* Sage tries to remember how to get the mouse to the screen07:45
Stskeepsuxlaunch remove nocursor?07:45
SageM_USE_SHOW_CURSOR env var07:45
Stskeepsor that07:46
Sagewell did both :)07:46
Sagedidn't help :/07:47
Sageok, so something else needed as well07:47
Sagehmmp. some xorg option was needed07:48
Sagemaybe it was Option "HWCursor" "off"07:50
Stskeepsdo you have Xorg.0.log somewhere?07:50
Sagehttp://pastebin.com/svYp1y2b07:51
Stskeepslooks correct07:53
*** veskuh has joined #nemomobile07:54
Stskeepsi wonder why the composition is so slow though07:55
Stskeepswell, besides the fact it'd be compositing 1920x1280..07:55
*** Anssi138 has joined #nemomobile07:57
Sage\o/07:57
Sagemouse07:57
Sage        Option          "SWCursor"  "on"07:57
SageUnder "Screen" section in /usr/share/X11/xorg.conf.d/99-pvr.conf07:58
Sageactually this works much better than last time I tested07:58
Sageyou can actually use this now to some extend07:59
Stskeepshmm07:59
Stskeepsfps?07:59
Sageon application grid 1508:00
Sageapp grid 4 (with widgetsgallery showing)08:00
*** norayr has joined #nemomobile08:00
Sageon widgetsgallery 9-1508:00
Sageyes it is slow, but still much better than last time08:00
Stskeepsok, but isn't systemui still going crazy?08:01
SageI don't have that running :)08:01
Stskeepsok08:01
Sagestarted only, mdecorator, compositor and home08:01
Sagewithout any apps home is 18FPS08:02
*** tibs has quit IRC08:03
Stskeepsok, try to kill compositor and then widgetsgallery on it's own08:03
Sagek08:04
Sage22FPS08:05
Stskeepshrm08:06
Stskeepsi don't presume you can set resolution to something lower?08:06
SageXorg and widgetsgallery taking 100% cpu constantly08:07
Stskeepsthat's not good08:07
Sagelet me try with plain xterm08:07
Sageyup, with plain xterm no cpu usage08:08
Sagelol, cpu usage comes from FPS meter08:09
Sagewithout that no cpu usage08:09
Stskeepsok :P08:09
Sageso that is probably slowing the ux down as well08:09
Stskeeps-log-fps instead?08:09
* Sage tries08:09
Sagewhere does it put it?08:10
Stskeepsstdout or $PWD08:10
Sagesame 2208:11
Sageand huge cpu usage08:12
Stskeepsawkward08:12
w00tfps meter is not a surprise08:14
Stskeepsanyway, see if you can somehow drop to 800x60008:14
w00twhen measuring fps, naturally, the application is forced to redraw constantly (even if it doesn't need to) and as fast as it can08:14
*** tibs has joined #nemomobile08:15
*** beford has quit IRC08:37
* Stskeeps preps new prerelease08:38
w00tso was there any consensus about 4.8 problems?08:40
Stskeepsi'm not confident it was related to it08:40
w00t\o/08:40
w00t:P08:40
Stskeepswe're downgrading input proto at least08:40
* w00t cancels the ticket to columbia08:40
*** tibs has quit IRC08:42
SageStskeeps: did cp N900.conf Default.conf and got smaller display generated, however Xorg still pushes the full HD out and fps about the same08:43

veskuhHow old resource engine we have? There is definitely some issues with it or with the way we use it. the occasinal dialer issues seem to be related to resource use08:50
veskuhother possible quilty party might be audio pipeline since the problems are related to ringtone08:50
Sageveskuh: resource engine? As resource policy?08:51
Stskeepsn900 or n950?08:52
*** araujo has quit IRC08:53
veskuhOn n950. the issue might be in the policy or the engine08:53
veskuhI'm assuming the engine is libresource?08:53
SageStskeeps: we don't have xrandr in mer?08:55
*** tbf has joined #nemomobile08:55
Sagewe have lib, but where should the binary be?08:56
Stskeepsok, it might be that we don't have the tool08:56

Sageat least in xorg log it says that08:59
Stskeepsso it does 22fps at 800x600? hmm08:59
Stskeeps:P08:59
Sagewell, it outputs the full hd still to screen09:02
Sageso that xorg conf did nothing09:02

Sagegestures work now though14:00
Sagedid the qt upgrade touch to the touch patches we had there?14:01
Sagesystemui is still acting up as well14:01
Stskeepshttp://review.merproject.org/#change,31214:02
Stskeepsyeah, but systemui acts up on old core too14:02
Sagenot like this14:02
Sagewith old core systemui crashes at times yes. But it never goes to loop and takes 100% cpu14:02
Sageor at least I haven't seen that happening with curren core14:02
Stskeepslovely14:03
SageThe core it self seems ok, but qt seems to be acting up14:05
Sageno crashes, no odd messages14:05
Sagewell, timed seems to crash at times, but not sure if it does that also with current core14:06
Stskeepsok, i'll have a look14:06
Stskeepscould you do a x86 image too for comparison purposes?14:06

w00topengl needs FullViewportUpdate14:31
w00tas for the FPS, give profiling a shot14:31
faenilit needs fullviewport?14:32
faenilwhy :(14:32
faenilthere's no need to draw the UI every time...14:33
faenilabout profiling, it doesn't work on Qt for Android, it says the peer has disconnected, and doesn't start14:33
w00topengl is not like software rendering14:34
w00tit isn't necessarily always a performance hit14:34
w00ttry profile it on a desktop14:34
faenilit doesn't work on desktop for a bunch of reasons...14:35
w00tthen you're in trouble14:35
faenil(all related to my laptop)14:35
faenilyes I am...but is that a Qt thing? or OpenGL?14:35
w00tyou can either figure out a way to get some kind of performance metrics, or take random stabs in the dark and hope you find things that improve performance14:35
w00twhat?14:35
faenilthe fullviewportupdate14:35
faenilthe need for it14:36
w00tI don't know where the requirement comes from, I just know it exists14:36
faenilok..14:36
w00tI'd guess it's probably opengl-related though14:36
faenilI see...strange, strange..14:36
w00topengl is very much about a scene where as with software rendering you can just clip all your drawing to one section of the screen fairly easily14:37
w00t</uneducated guessing>14:37
faenilthat would sound new to me, but I'm no expert, so could be :)14:37
faenilone alternative could to redraw things myself14:39
faenilset NoViewportUpdate14:39
faenilproblem is, how do I tell qml components to repaint?14:39
faenilso you're basically telling me I can't set one context and draw a part of the screen14:41
faeniland then set another context and draw another part?14:41
faeniland draw the first part using the first context just once in a while?14:41
mikhasfaenil, how about trying QML2 first before wasting time optimizing old QML?14:43
faenilmikhas: you've already told me that, haven't you :D14:43
mikhasI guess.14:44
faenil:)14:44
mikhasIt bears repeating.14:44
faenilsure ;)14:44
faenilbut I wanted to know why it's not working this way :)14:44
mikhasI dont think that current stable QML gives you enough hooks to really get optimal performance.14:44
mikhasIf you want to get best perf out of QGraphicsView, do it in C++, not QML :-/14:45
faenilI thought a mix was doable via QDeclItem... :)14:45
mikhasthen one can disable all the Qt "convenience", like painter state saving and such14:45
faenilbut also loses all components14:46
mikhasfaenil, as a rule of thumb: count the amount of items that update during a paint event, and get that number down.14:46
faenilbut still, that's not a problem, I just wanted to know the tech reason behind the current failure :)14:46
mikhasthe claim that QGV easily supports a million items is only true for certain conditions (one of them being "runs on desktop")14:47
faenilxD14:47
faenilbut ui items do not update if you don't touch them14:48
faenilwhy are they redrawn14:48
mikhasyou need to call update on the item that is scheduled for redraw14:48
mikhasyou can work with FullViewport updates14:48
*** phaeron has quit IRC14:49
mikhas*if* you carefully enable device coordinate caching for the items that dont change14:49
mikhasbut that's QGraphicsItem API, not exposed to QML14:49
faenilI see...14:49
mikhasyou can expose it manually14:50
faenilI also hoped SmartViewportUpdate would help me :D14:50
mikhasI think I also explained that some time ago, somewhere.14:50
mikhaseh14:50
mikhasforget it, there is no silver bullet14:50
faenil:)14:50
mikhasfaenil, you can read "The Strategy" part in http://taschenorakel.de/michael/2011/05/10/painting-strategy-meegos-virtual-keyboard/14:51
faenilthanks :)14:51
faenilinteresting, interesting, thanks :)14:53
mikhasI also have code examples14:53
*** phaeron has joined #nemomobile14:53
faenilif this helps, my gl view doesn't have a fixed size..14:54
mikhasthat should not matter, although the reconfigure event for the widget itself will usually be expensive (or rather, lead to expensive repaints)14:56
faenilone thing is not clear14:58
faenilwhen you press the key it's drawn over the idle as overlay14:58
faenilbut when you release the finger, you have to repaint the idle keyboard (the whole one), don't you?14:59
faenilcoz that's one item, as you stated14:59
*** himamura has quit IRC15:00
mikhasfaenil, but it is redrawn from Qt's internal pixmap cache15:03
mikhasso no paint event is emitted15:03
faenilI see15:03
mikhasand no item redraws15:03
faenilcouldn't I paint a transparent background instead of the black one?15:04
faenilso that the UI is still shown but not repaint?15:04
mikhasyou can, but drawing transparent pixels is also expensive15:04
faenilyeah...15:05
mikhasQGraphicsView does not handle transparency well15:05
faenilI see...15:05
mikhasthe patches are all there, but it was decided to only fix that for Qt515:05
mikhas(I think it's a pure marketing stunt, the fix could have been done in Qt4 without public API changes)15:05
faenilwell, now that everything's somewhat clear, I'll wait for QML2 :D15:05
mikhasgood15:06
mikhasmission accomplished15:06
faenilahahaah :D15:07
faenilit should be out in April, right? or has there been any news about any delay?15:07
w00tthere is no date firmer than "sometime in summer (hopefully)"15:17
faeniloh, summer hopefully :O15:19
faenilmikhas: would you mind providing an explanation to another issue I'm having ? :D15:22
faenilI need a velocity attribute because I need to handle a pan gesture15:25
faeniland qt doesn't seem to offer anything like that..15:25
faenil(which is strange)15:25

lbteg yes... #1345#15:26
lbtor *#1345#15:26
faenilso I was trying to calculate the velocity by myself15:26
*** lizardo has quit IRC15:26
lbtOK, thanks Stskeeps15:26
faenilI get deltaTime, deltaTransl, and calculate velocity at each touch event15:26
faenilbut deltaTime and deltaTransl are incoherent, thus resulting in unreal velocity values...15:27
faenildeltaTime is 1-2-3ms most of the times (80-170ms some times)...15:27
