<libv> ssvb: what mali issue?
<libv> oh, the crash
<libv> that part is resolved
<libv> i will send in a patch after some sleep
<libv> i however do see the debug messages from fbturbo talk about ump id 1, whereas my mesa driver only gets to talk about ump 3
<libv> and, when rendering to ump 3, i am rendering to the actual fb and not to the overlay, therefor seeing some pixels move in the background while the overlay stays black
<libv> this is the reason why the kernel crashed: i am addressing a different size (that of ump 1 ~350kb) than the buffer size (that of ump 3 ~18MB)
<ssvb> libv: ump 3 should span span over the whole framebuffer, and 'flags' in the DRI2BUFFER structure sets the offset where the actual picture begins
<ssvb> libv: for ump buffers allocated in normal memory, this offset is normally set to 0
<ssvb> libv: the size of ump 1 is somewhat suspicious
<libv> no, it's ok for 300x300x4
<libv> hrm, flags entails an offset?
<libv> ouch.
<libv> so i have to ump attach size + offset, and then add the offset
<libv> yikes.
FDCX has joined #linux-sunxi
<libv> so it is not possible to get separate ump buffers out of disp?
<ssvb> it might be possible, but so far it was not really necessary
<libv> ssvb: also, i do not seem to get any DRI2InvalidateBuffers events
<libv> the stamps always match and i never know if i need to get new buffers
<ssvb> for invalidate events I don't remember exactly, but I think there might be a patch
<ssvb> let me check it again
newleaves has joined #linux-sunxi
<ssvb> libv: at least I have seen these events at some point - https://gist.github.com/ssvb/5453379
<ssvb> libv: and I don't remember if I really needed this patch, but I have tried it earlier - http://lists.x.org/archives/xorg-devel/2012-September/033790.html
_newleaves_ has joined #linux-sunxi
<ssvb> libv: looks like some investigation might be needed :)
<ssvb> libv: and the timestamps should be indeed also checked
<ssvb> libv: but wait a second, DRI2InvalidateBuffers should only happen when buffers are destroyed, for example on window resize
<ssvb> libv: DRI2BufferSwapComplete is perhaps more interesting for you

<song_> by following http://linux-sunxi.org/Binary_drivers, after installing binary packages "xserver-xorg-video-sunximali sunxi-disp-test", X fails to start. in /var/log/Xorg.0.log, it shows No devices found, no screens found. should I remove the binary driver? thanks.
<libv> song_: i should throw out that section.
<libv> song_: just build it, as above
<libv> song_: what distribution are you using?
<song_> libv, this is the entire output: http://paste.ubuntu.com/6748957/ I am using ubuntu. upgrade to 13.10. kernel is "Linux cubietruck 3.4.61+". thanks.
<song_> not entire. partial output.
<libv> song_: first off, throw out the mess from the cubian stuff
<libv> song_: all of it
<libv> song_: you did see the warning in bold there, no?
bsdfox has quit [Ping timeout: 260 seconds]
<song_> libv, I saw it. I will remove that binary. thanks. I am a newbie. I am a little bit confused. I have mali and ump module loaded. do I still need to compile mali binary drivers? what is the different between compiling mali binary drivers and already loaded mali module? thanks a lot.
<libv> song_: did you see this? http://linux-sunxi.org/Packages
<libv> this will get you ssvb's fbturbo driver
<libv> you can then go and build the sunxi-mali repository
<libv> which does little more than overwrite the libump you just pulled, and then installs the binaries in your system
<libv> and the matching headers.
bsdfox has joined #linux-sunxi
<song_> libv, thanks. I never know there is a repo for sunxi. after installing fbturbo driver, do I still need to do this section "Installing the Mali binary drivers" in http://linux-sunxi.org/Binary_drivers?
<libv> 07:24 < libv> you can then go and build the sunxi-mali repository
<libv> song_: i just do not provide packages for the binaries
<libv> song_: i should at one point in the future, and this future keeps on moving out, provide the lima mesa driver
<song_> libv, I think I can skip this section "Setting up X" because I already have fbturbo driver, right? thanks.
<libv> song_: apt-get install xf86-video-fbturbo
<libv> song_: but _first_ fix the crap you just pulled by ignoring the big fat warning.
<song_> libv, I have purged the three packages from cubian. thanks.
<libv> song_: and the packages that got removed?
<song_> libv, do I need them? only 4 packages removed. libegl1-mesa libqt4-declarative libqtgui4 vlc. I know I can ignore vlc.
<song_> btw, there is no package xf86-video-fbturbo. I think it should be xserver-xorg-video-fbturbo.
<libv> true
<song_> libv, do I need the 4 removed packages? thanks.
<libv> song_: how would i know?
<libv> song_: xserver-xorg-video-fbturbo does get its own dependencies though
<song_> libv, thanks. I thought you knew everything. you saves my life. ^_^ i just install them except vlc.

<libv> song_: only one person currently has this file installed in his systems
<libv> song_: you just do not have AIGLX
<song_> libv, ok. got it. then, it's no worries. btw, did you see my make test error message? do you have any ideas? thanks.
<libv> song_: i ran into the same thing yesterday
<libv> song_: you need to install some libX11 packages
<libv> song_: check whether that file exists
eebrah|mobile has quit [Read error: Connection reset by peer]
<libv> if not, apt-cache search for it, and install the resulting package
<song_> libv, which file? I have libX11.so.6 which points to libX11.so.6.3.0
eebrah|mobile has joined #linux-sunxi
<libv> then look for the -dev package which holds libX11.so
<song_> maybe the true error is "undefined reference to symbol 'XNextEvent'". thanks. let me see.

<ssvb> libv: can you paste xtrace logs somewhere (for odroid and for sunxi)?
<libv> ssvb: is there really no other solution to this stuff?
<libv> i will have to reach deep down into the limare memory management now
bsdfox has quit [Ping timeout: 246 seconds]
<libv> ssvb: the resizing bug can be dealt with in a bit
<ssvb> libv: solution to what stuff? fbturbo is doing some wrong things mostly to please the r3p0 blob, if updates are needed for lima then they can be done
<libv> solution to having one humongous ump buffer
<libv> and instead having a separate ump buffer in the disp fb area
<libv> or does sunxi-disp/ump simply not allow for that atm?
* libv hasn't looked into ump beyond what he has needed so far
<ssvb> more like the mali blob is very sensitive to secure id numbers
<libv> but the mali blob doesn't care whether it is fb or something else, right. ump should abstract at least that much
bsdfox has joined #linux-sunxi
bsdfox has joined #linux-sunxi
<ssvb> the mali blob cares about secure id numbers
<ssvb> if secure id number is less than 3, then mali blob considers it to be framebuffer
<ssvb> if we start allocating more buffers, they will get new secure ids which are larger than 2 and the mali blob will be unhappy
<libv> ssvb: is there infrastructure to repackage existing memory from userspace and get a fresh secure id for it?
<ssvb> not sure about this, but something can be created for lima
<libv> no time, i hope i can get by by not touching the limare memory infrastructure
<song_> first, the problem is solved by adding "-lX11" to test/Makefile. if this flag has to be there, i don't know why it's not there.
<libv> heh. i can't.
<ssvb> libv: we could have a new ioctl for allocating new physically contiguous ump buffers, which should be possible with cma
<libv> ssvb: no time.
<song_> second, test/test, text output is fine. but I don't see a triangle. just black X window. is this ok? thanks.
<ssvb> libv: anyway, I need to leave now
<libv> ah, good, i can get by without rewriting my memory infrastructure.
<libv> ssvb: ok, thanks

<libv> ssvb: but really, this code should get to a slightly useful state, get cleaned, and go out, and then these things can be fixed properly

<libv> err, wifi
<libv> heh, thanks to my slight optimisation, i am running the cube companion 40% faster than the binary
<libv> es2gears is slower, due to C++ code in mesa for looking up symbols. i will optimize that now as i need to wait for ssvb to come back

<song_> btw, I am trying to compile https://github.com/linux-sunxi/libvdpau-sunxi, "make" returns "vdpau/vdpau.h: No such file or directory". it's true. the git repo does not have that directory. I am confused. thanks.

<song_> oliv3r, vdpau/libvdpau-sunxi.so is not there. I remembered it installed somewhere else. let me see.
<oliv3r> then there's 2 things going wrong :)
<oliv3r> a) you need /dev/cedar_dev; if you do not have it, you need sto modprobe sun4i_cedar_dev
<oliv3r> b) find where vdpau expects its shared libs; and move that file to where it expects it :)
<oliv3r> it might be that debian has it elsewhere by default
<song_> oliv3r, I have /dev/cedar_dev. make install simply install to "/usr/lib/arm-linux-gnueabihf/vdpau/libvdpau_sunxi.so.1"

<oliv3r> song_: no, my kernel is OLDER
<gzamboni_> afaik the plataform registers adresses data are different as the Cortex version of the SoC
<song_> oliv3r, the old kernel has problems with cubietruck. I think you are not using cubietruck.
<gzamboni_> AW has done it using sun8w1 sun8w3 sun8 and sun9
bsdfox has quit [Read error: Operation timed out]
<song_> oliv3r, I tried that. it didn't work. actually, I think /usr/lib/arm-linux-gnueabihf/vdpau is the right place. because i saw libvdpau_trace.so.1.0.0 is generated.
<song_> maybe that is not generated. I am completely new to this. anyway, I will try patrickhwood's kernel later today.
<gzamboni_> do the A10 and A20 share the same plataform.h address data ?
<oliv3r> gzamboni_: i'm using sun4i_cedar_dev on 3.4.61+ on my ctwith hansg's fedora 19-r3 build and works fine
<oliv3r> song_: i'm pretty sure i've got a cubietruck
<oliv3r> song_: though I'll admit, i got this from benn as the developers edition, so maybe it's different
<oliv3r> also, a20 is a20, if it's cubietruck or cb2 does not matter
bsdfox has joined #linux-sunxi
<gzamboni_> my theory of the plataform data beeing related with the Cortex Ax is not correct
<oliv3r> gzamboni_: it works fine for me

<oliv3r> but that's an interesting measure
<oliv3r> i have a nother a20 at home, but i bet that's aa aswell
<oliv3r> i thought ofg a nice feature request for their AXP line of PMU's. QI charging standard :D
<gzamboni_> you're right, i will try to port to 3.4 before going to 3.10
<oliv3r> gzamboni_: i ment 3.14 with mainline :p
<oliv3r> i wouldn't worry to hugely about 3.4
<oliv3r> as we have spi there; dma engine, wwhile really nice, won't that be a lot of work?

<oliv3r> i have lots of 2.54 headers (IDE) but hardly any 2 mm parts laptop connectors
<oliv3r> how many pins do you need to convert? will an old-skool laptop connector work?
<mripard> 5 pins would be enough
<mripard> so, nothing really
<mripard> ccaione: nope, didn't try on farnell
<mripard> I never find my way in the farnell website :)
<hramrach> mripard: try to find a 44pin to 40pi IDE cable
<oliv3r> that's what i just said :p
<hramrach> they should be available off-the-shelf too
<hramrach> from any larger PC component store
<arete74> mripard, hi i have send an little patch for change A1X in sunxi, yu have review?
<mripard> hramrach: hmmm, good to know
<mripard> arete74: yeah, it's in my Inbox, I have to reply to it
<oliv3r> hramrach: 44 -> 40 is really old skool though; i doubt they have it 'commonly'
<mripard> oliv3r: amazon has it
<oliv3r> lucky you!
<mripard> I didn't know those were 2.54 and 2mm actually
<oliv3r> mripard: what are you hacking? :)
<oliv3r> :)
<mripard> A31 EVB :)
<oliv3r> throw that out, get an A23!
<mripard> for that matter, A23 and A31 is the same
<mripard> it's the same SPI controller
<oliv3r> ah SPI hax
<oliv3r> i really wanna start comparing a23 and a31 memory controller
<wens> wonder how hansg is doing; he's working on 3 or 4 drivers at the same time
<hramrach> oliv3r: it's still good for servicing slightly dated laptops. that's why you need large store to have it, not just any store.
<mripard> oliv3r: hramrach: thanks :)
<oliv3r> wens: he was steamrolling things yeah
<oliv3r> hramrach: yeah very true; my laptop still takes 40 pins :)
<wens> oliv3r: I tried working on 3 things at once, ended up blowing up my tree
<oliv3r> that
<oliv3r> and i end up finishing neither
<oliv3r> i have 4 or 5 things i try working on

<song_> oliv3r, hi, I have installed the latest kernel. everything is working. 2d/3d acceleration is working. but I still fail to run "mplayer -vo vdpau". what is the best way to play 1080p vidoes? should I install vlc with cedarx instead? thanks.
<nove> song_: do mplayer -vo help, does it have vdpau support?
<song_> nove, there is no vdpau in "mplayer -vo help".
<nove> song_: then install mplayer2
<song_> nove, thanks. I will do that now.

<oliv3r> ok'll update the wiki
<oliv3r> nove: disp is responsible for downscaling?
<nove> oliv3r: yes to fit in the viewport, the decoder has /2 /4 /8 downscale but i don't think that is using it
<nove> oliv3r: or is only mpeg subengine that has this /2/4/8
<oliv3r> nove: if the decoder can do some preliminairy downscaling; we could still decode 4k content
<oliv3r> but that's far on the wish list i guess
<oliv3r> do disp is limited to < 4k resolution
<oliv3r> so*
<nove> oliv3r: is too slow, jemk got around 10fps
parabyte is now known as Kingb4King
jemk has joined #linux-sunxi
<nove> oliv3r: but i think A31s and maybe also A23 can decode and display by hdmi 4k
<oliv3r> the decoder rescaler is to slow?
<oliv3r> well hdmi 1.2 and 1.3? are limited to 1920x1200 aren't tehy
<nove> the decoder in general
<oliv3r> it's a shame that you get garbage output though; would be really been cool to make it decode @ 4k
<oliv3r> it's ok if it can't output it, that could be expected; but now you get no display at all
<nove> there is a video in armdevices of mele 4k, show 4k @30fps playing in a system that is not android, but called simple linux
<oliv3r> nove: i'll look that up
<oliv3r> what's the title called about?
<nove> oliv3r: ^

<oliv3r> but that's a31 :(

<oliv3r> it's not 4k!
<oliv3r> it's 3840x2160
<oliv3r> and if i'm not mistaken; that's 2k really
<jemk> a31 is advertised as 4k capable, a20 only 2160p, so it's possible
<oliv3r> 1080p; 2160p
<oliv3r> jemk: hey jemk! didn't see you join
<oliv3r> jemk: http://linux-sunxi.org/Cedrus if you could glance that over
<jemk> hi, still backreading
<nove> 3840x2160 is what they will call 4k
<oliv3r> oh i allready see i used [i] incorrectly ;)
<oliv3r> nove: they lie :(
<nove> is 3x(1280x720) and 2x(1920x1080), is a good resolution for playing video
<oliv3r> it is a good resolution
<oliv3r> but 1920x1080 would then also be called 4k :)
<oliv3r> but really it's only 2k then :)

<enrico_> jemk: h264 encoder working on olinuxino a20
<enrico_> jemk: actually i wrapped it into a gstreamer plugin, works good
<enrico_> jemk: i will release the source once i clean it up a bit
<jemk> enrico_: wow, nice
<jemk> but note that this is still very early version with lot of limitations
<oliv3r> the gstreamer plugin using libvdpau-sunxi
<enrico_> yes i noticed, but a good start
<enrico_> i found only a small bug in ve_malloc, there is no error check for mmap return (could be MAP_FAILED), happened to me when passing size=0 by mistake
<enrico_> oliv3r: not that plugin, a new one, ideally to be used for all encoding (mpeg4, jpeg...)
<oliv3r> so decoding will be done via vdpau; encoding via gstreamer dedicated plugin?
<oliv3r> or will you do both via gstreamer
<nove> i give out, this mplayer give no video found in software mode
<nove> enrico_: nice
<enrico_> does a gstreamer plugin already exists for vdpau sunxi?
<enrico_> right now i'm only interested in encoding, so i'm doing it for encoding only
<oliv3r> jemk: nove: btw, even if prescaler is only 10fps; i think it's still better then green mishmush
<enrico_> but it could be expanded later for decoding (if it doesn't exist already)
<jemk> oliv3r: the prescaler would be fast enough, but vdpau doesn't tell me how big the output has to be at decode time
<oliv3r> jemk: so you need to know before decoding starts, the size of the final output; e.g. if you have to use the scaler or not
<oliv3r> jemk: that sounds like a big shortcomming of vdpau :S
<jemk> exactly
<oliv3r> hack vdpau!

<gzamboni_> i did manage to compile the dma code on 3.10
<oliv3r> sweet

<vrga> i feel ya.
<vrga> broke a screen on my tablet recently, couldnt bear not to repair it.

<aexl> nice. the glass of my tab is broken since a while. doesn't bother me really. ^^
<oliv3r> aexl: awesome; i think we have u-boot etc support
<oliv3r> aexl: hardly :p
<oliv3r> aexl: soldering that will be a huge undertaking
<oliv3r> well you'd need a scope to measure the axp's outputs
<oliv3r> see if they all work at all
<oliv3r> vrga: 23$? wow; that's a hella expensive repair. you can get an A23 based tablet for 29S now?
<vrga> oliv3r, yer shittin me?
<vrga> damn.
<vrga> and that was the cheapest screen i found....
<vrga> the local repair shop wanted to charge me $140 or so for the screen replacement and repair for a tab that cost barely $100 here 8 months ago
<aexl> oliv3r: only got a "graphical display meter" Voltcraft GDM 705 http://home.arcor.de/bernd_kunze/gdm703.htm
<oliv3r> maybe; the axp outputs should be DC, so should be measureable
<vrga> oliv3r, that shipping price is a ripoff
<vrga> $80? what the hell?
<oliv3r> that's probably via dhl :p
<oliv3r> 30 USD to NL
<oliv3r> find diff vendor
<vrga> but ideally i'd be looking at some dual core 1GB tab rather than the current cream of the 512mb crop...
<aexl> vrga: so it's $48.
<vrga> aexl, 34-40$ + 80$ shipping for croatia :p
<aexl> shipping €19 to germany ... :/
<vrga> i think i'll stay happy with my 23$ screen purchase and trivial replacement of the screen :p
<aexl> cheaper than the 512mb tablet.
<aexl> these pages also don't mention brightness. so i'll never know if i can use it outside.
<vrga> i personally find it uncomfortable to use the tablets anywhere outside anyhow.
<aexl> enough for some browsing and little gaming.

<rellla> oliv3r: i don't believe c't is GPLed ;)
<oliv3r> 1 foto concists of fair use :p
<oliv3r> besides, a foto of the magazine is your art isn't it
<oliv3r> vrga: there was other arm board before the pi
<oliv3r> the pi had lots of marketing push
<oliv3r> and it was very cheap
<oliv3r> even LIME has a hard time competing
<oliv3r> (price wise)
<rellla> oliv3r: maybe tomorrow evening, we can find something online.
<rellla> somewhere.
<mripard> mrnuke: I don't know, what's happening?
<oliv3r> likley
<oliv3r> mripard: using u-boot? or core-u-boot?
<oliv3r> er mrnuke
<mrnuke> mripard: nothing.
<mrnuke> oliv3r: pure uboot
<oliv3r> you setting fdt_high?
* rellla should search wikipedia what is meant by a "scanner"?
<mrnuke> oliv3r: yeah, just as the wiki page suggests
<oliv3r> those instructions should work
<oliv3r> i've booted otns of ML kernels
<mrnuke> OK, I'll try it again, line for line from the wiki
<mripard> mrnuke: something must be happening, otherwise you just didn't power your board.
<mripard> if it doesn't try passing earlyprintk to the kernel command line, with CONFIG_DEBUG_LL enabled
<mrnuke> not powering my board? really? ID10T debugging :p. http://fpaste.org/68432/97364401/
<oliv3r> and console=tty0,115200
<mrnuke> so "bootm kern - dtb console=tty0,115200" ?
<mrnuke> or ttyS0 ?
