Stskeepsdoes any of you have working h264 playback on mer r-pi yet?09:32
kulveI had some problems getting the wifi working, so I'm actually now testing if the nexus7 kernel would work on my reference board as well. That would make certain things easier09:32
Stskeepskulve: connman-test may be useful, connman is a bit rfkill-y09:32
kulveStskeeps: problems are related to the driver and/or firmware, not user space, I guess09:33
kulveh264 playback works on RPi. But not with gst09:33
Stskeepsok09:33
kulvealthough I have been focusing more on tegra lately. I guess you can still decode on RPi with gst but not render09:34
Stskeepsi has new apartment, so it's time to think about how to put the r-pi's into usage, so :P09:34
Stskeepsoh come on, wiki.meego.com can't be down.09:37
vgradeI wonder if we could use the same approach that Rob Clark used om omap with eglRender09:37

ali1234are we still seriously at a point where there's no window borders?10:48
Stskeepsali1234: CSD is always a joy of fun to discuss10:48
Stskeepsali1234: qt apps have CSD at least (i think) but in most cases you don't want those on mobile anyway10:49
vgradeStskeeps: keyboard yes10:49
ali1234every window should have the exact same decoration regardless of whether it is Gtk, Qt, Motif, or raw xlib. if wayland can't deliver that it will not be accepted.10:50
ali1234maybe it will be accepted on mobile, but not on desktop10:51
Stskeepsali1234: it can have decoration fine - in qml compositor you simply wrap it around the buffer10:51
Stskeepsbut about the client side decorations i don't understand some people's opinion to have them in toolkits..10:52
Stskeeps:P10:52
Venemo+110:52
Stskeepshttp://releases.merproject.org/~carsten/qmlcompositor.png is CSD, i think10:53
ali1234what do you mean "in toolkits"10:53
Stskeepsin gtk/qt/motif, etc10:53
ali1234well i agree10:53
VenemoCSD=?10:53
ali1234they should only be implemented once10:53
Stskeepsi don't understand why it has to be there10:53
StskeepsVenemo: client side decorations10:53
Stskeepsie, app draws it's borders10:53
Venemowell, they have their reasons10:54
Stskeepshttp://releases.merproject.org/~carsten/qmlcomponentgallery.png - it's not hard to imagine drawing a border around those windows as they're just qml elements10:54
Stskeepsvgrade: good work, btw :)10:56
Venemofor example, the status bar on harmattan and nemo is a CSD, a hack that allows every app to run fullscreen (getting the perf advantages of being fullscreen), but actually looking non-fullscreen10:56
Stskeeps:nod:10:56
*** Sfiet_Konstantin has joined #mer10:56
kulvecsd?10:56
Stskeeps[11:53] <Stskeeps> Venemo: client side decorations10:56
kulveah, nm :)10:56
kulvejust wondering, because the statusbar is completely broken on my hardware10:57
Venemofor some reason, there is a huge perf impact when the compositor starts drawing things... see fremantle's titlebars or the notifications in harmattan10:57
faenilVenemo, +1000 to that10:57
Stskeepskulve: oh, is sysuid actually running?10:57
faenilI hate that thing10:57
faenilwhenever a notification appears, FPS drops to 2-310:58
faenilit's the same in Nemo from what I've seen so far10:58
Venemoalthough it might be different in wayland10:58
Stskeepscomposition is slow and should be avoided10:58
Stskeeps:P10:58
kulveStskeeps: I don't know what sysuid is. I see the status bar after a boot but soon I can see just background on that area10:58
Stskeepskulve: yeah, ps aux | grep sysuiid10:59
Stskeepssysuid10:59
Stskeepsit's the thing handling the status bar10:59
VenemoStskeeps, but is it the same in wayland as well?10:59
kulvewill do, if I get this to boot again. I left my debug board at work thinking that I don't need it. But I'm actually trying to get a new kernel up'n'running so that would be quite useful..10:59
StskeepsVenemo: it really depends on how you want to do it11:00
StskeepsVenemo: nothing stops you technically from getting a buffer that you drop in yourself and show11:00
VenemoStskeeps, so how is it worth doing it?11:01
Stskeepsdoing..?11:01
Stskeepsit, i mean :)11:01
* Stskeeps ponders idly if he should give Venemo a crash course in qml compositor..11:02
Venemowhy not?11:02
faenilme too me too :D11:02
Stskeepswell, https://wiki.merproject.org/wiki/Zephyr is a good start11:03
Stskeepsget that kit up and running and it's easier to start develop with11:04
VenemoI don't have any hw with me right now11:05
Venemobut I'll definitely try11:05
Venemowhat surprises me a little is that you are working on this. I thought wayland is not yet in the scope11:07
Stskeepswell, the reference device is virtualbox11:07
StskeepsVenemo: as with anything, it's better to be ahaed11:07
Stskeepsthis is what will enable us to put stuff on android hardware adaptations with ease11:07

Bostikfrom what I've gathered, there exists a rebuilt rpi shim with native wayland display type...11:09
StskeepsBostik: well, we have r-pi wayland + qml compositor too11:10
Stskeepsbut yeah, native support even better11:10
VenemoStskeeps, how is this related to android? I thought you could just use X there too11:10
BostikI like lean stacks :)11:10
StskeepsVenemo: you'd never be able to get opengl es11:11
StskeepsVenemo: zephyr's related to android through libhybris, where we can use existing android hardware adaptations11:11
StskeepsVenemo: and put wayland on top11:11
Venemoisn't that what libhybris does? (getting opengl es)11:11
Stskeepssure, but it wouldn't work for x1111:11
Stskeepsor at least, sanely11:11
Stskeepsdri2 would be a pain in the ass to add11:12
Venemomhm11:12
Stskeepseither way, if you want a lean and mean stack, you don't want x1111:12
Venemoby dri, you mean direct rendering infrastructure?11:12
Stskeepsyeah11:12
VenemoI see.11:13
Venemoand yeah, I agree about X not being a sane stack at all11:13
Stskeepsso that's why we have zephyr.. and zephyr would be useful for even lower end too11:13
Stskeepswith shm only stuff11:13
Stskeepsshm being sw rendering/raster engine etc11:13
kulveStskeeps: I did see a status bar there couple of times but at least currently, the status bar area is just garbage and no sysuiid process is running11:14
Stskeepskulve: yeah, so it crashed11:14

Stskeepsdiving deep into android graphics driver specifics14:39
Stskeepsit's not so nice14:40
*** KaIRC has joined #mer14:40
javispedroTbh I don't like that it has come to having to scrape android graphics drivers to get ARM boards to work..14:45
javispedrobut, well, not much can be done by now.14:45
javispedroother than what you are doing :)14:45
Stskeepsyeah14:46
Stskeepssaw that thp got NDK apps working too?14:46
javispedroI did not know that NDK apps did not have dalvik stubs14:47
Stskeepsi didn't know NDK apps were actually .so's14:47
javispedrooh14:47
javispedroI thought all of them were JNI .so's.14:47
Stskeepsthat was a bit of a shocker to me14:47
Stskeepsyeah, JNI .so's14:47
Stskeepsi thought binary exectuables14:47
javispedroso, what does he do with the dalvik stubs?14:47
javispedroaaah, they're probably generic enough for some apps to work14:48
javispedromakes sense14:48

*** arcean has quit IRC14:57
Venemono, I'm sorry. I answered to a half an hour old question14:57
Venemo[15:26] * Stskeeps ponders idly if qt5 + qtdeclarative and other modules can be statically linked together14:57
Stskeepsah14:57
Stskeepsgood14:57
Stskeepsand next question, how big that binary would be..14:57
VenemoBIG14:57
Stskeepsyeah, but >250mb?14:58
Stskeepsstripped, too14:58
VenemoI don't think it'd be that big no14:58
Venemowell, the only place where I've seen similar is when someone statically links Qt to his app. I didn't see parts of Qt itself statically linked together yet14:59
Stskeepswell, that's maybe a different direction14:59
Stskeepsthe question is always "how low can mer go"15:00
Venemowould it bring any advantages to statically link Qt itself together?15:00
Stskeepswell there was a significant discussion on load times, as an example15:00
Stskeepsno need to do relocations really15:01
Stskeepscombine that into a runtime with fork()ability like meegotouch-applauncherd..15:01
VenemoI see.15:02
Venemowould it improve the load time even if all the libs have been loaded?15:02
Stskeepsi mean, they'd have been loaded already when you fork()15:02
*** sp3000 has quit IRC15:03
Stskeepsjust thinking out loud :)15:03
*** sp3001 has joined #mer15:03
*** sp3001 is now known as sp300015:03
*** arcean has joined #mer15:04
Venemoyes, but if they'd've been loaded already, what advantage does it give to have it as a single, big lib?15:04
Venemowhy not just make a single binary which would load all the libs and which would then fork() ?15:04
Venemobtw Stskeeps, how exactly does the applauncherd work?15:07
Stskeepsit loads and pre-creates some things and then fork and dlopen's your app15:08
Stskeepspre-creates as in objects, like, for example, stuff needed for qdeclarativeview15:09
Stskeepsand your app takes over those objects in your own address space15:09
Bostikoh, maemolauncher all over again15:09
Bostikand zygote...15:09
VenemoStskeeps, afaik it just creates QApplication and QDeclarativeView instances15:10
lbthmm how to debug systemd on poweroff15:11
lbt"Stopped Connection Service" ... then hangs15:12
StskeepsBostik: yea, but considering the benefits..15:13
StskeepsVenemo: sure, that's one of the purposes15:13
Stskeepslbt: systemd.log_level=debug systemd.log_target=console15:14
Bostiklbt: can you attach strace to systemd before shutting down? that gives at least some hints as to where to look at (last accessed paths)15:14
StskeepsVenemo: that alone takes time :)15:14
VenemoStskeeps, yeah.15:14
VenemoStskeeps, the real win though would be if the results of the JIT compile could be cached15:14
lbtStskeeps: vbox vm - so the console goes away15:14
StskeepsVenemo: or pre-loading qml components..15:15
lbtBostik: could do that15:15
VenemoStskeeps, that too.15:15
Stskeepslbt: if you're into machocism, vbox supports serial ports15:15
BostikStskeeps: aye, the benefits are pretty clear - and I remember even seeing some design docs for maemo-launcher, where the stated reason started up from "app launch time" :)15:15
lbteek15:15
VenemoStskeeps, or maybe, just maybe, making qml components less bloated15:15
* lbt thinks video of console may be better :)15:15
Stskeepslbt: if you end up going down that road, socat is your friend and unix sockets15:16
