<Turl> oliv3r: you were writing PWM weren't you?
<oliv3r> Turl: started it, why? if you want to do it; go for it
<Turl> oliv3r: I found people wrote it already on cubieboard chinese forum :O
<oliv3r> gotta finish sid, rewrite it to mtd :p
<oliv3r> for mainline?!
<Turl> oliv3r: might be of help to you
<Turl> yes lol
<oliv3r> *sigh* why people never submit patches!
<Turl> huge url incoming
<Turl> http://translate.googleusercontent.com/translate_c?act=url&depth=1&hl=es&ie=UTF8&prev=_t&rurl=translate.google.com&sl=auto&tl=en&u=http://forum.cubietech.com/forum.php%3Fmod%3Dviewthread%26tid%3D508&usg=ALkJrhh9nqmElZt1ua-kXCiMMAijjeFg0Q
<Turl> at least I understand that looking at the translation, I didn't look at the code yet :)
<oliv3r> Your client has issued a malformed or illegal request. That's all we know.
<Turl> heh
<oliv3r> wait i'll copy paste it differently
<oliv3r> works
<oliv3r> it's in spanish of course
<oliv3r> it's a good thing i know english in spanish
<Turl> oliv3r: lol
<oliv3r> kernel 3.9, dt; yeah looks like
<Turl> the text inside should be in english
<oliv3r> you know whats really sad
<oliv3r> that guy obviously has no clue whats happening around him
<oliv3r> he patched u-boot to support fdt
<oliv3r> missing the fact that sunxi-current has fdt support
<Turl> oliv3r: yeah I think that is why it says novice all over the post :)
<oliv3r> i think he defines the pins using dts, and doesn't use pinmux
<oliv3r> let me read the rest first :p
<Turl> oliv3r: pinmux is defined on dts :P
ibrah has quit [Quit: Leaving]
<oliv3r> ah your right, i overlooked it
<oliv3r> i'm just glancing, thought he was doing the pins manually :)
<oliv3r> with the definition from dts however
<oliv3r> so is this GPLed? :)
<Turl> I dunno :P I can ask :)
<oliv3r> oh spotted the first booboo
<oliv3r> he defines for pwm0 regoffset 0x4, and for pwm1 0x8; like sun5i only uses pwm0 and sun4i uses pwm1 and pwm0
<oliv3r> but what about regoffset 0x0 :)
<oliv3r> it's not there
<oliv3r> bah can't download the zip

<oliv3r> rellla: do you know about german domains and denic.de?
<rellla> oliv3r: i have some. but never registered directly at denic.
<oliv3r> I have a .de domain (don't ask) which I moved from 1 registrar (that went backrupt) to namecheap.com; alls fine and it runs on namecheap since april; but now they've sent me a bill for 'pflege'
<oliv3r> if i don't pay before july 15th they'll 'delete the domain'
<oliv3r> does that mean they'll delete it from wherever I host it?
<rellla> hm.
<rellla> bill directly from denic?
vicenteH has quit [Ping timeout: 246 seconds]
<oliv3r> yeah
<oliv3r> 50 Euro's :)
<rellla> haha.
<oliv3r> 'Sie haben die moeglichkeit einen anderen provider mit der verwaltung ihrer domains zu beauftragen bzw. ihre domains sofort so loeschen'
<rellla> i get only bills from my hoster(s) - 1&1 :( and hosteurope
<oliv3r> but i've moved it since april, so it's hosted elsewhere just fine
<rellla> sounds like phishing ;)
<oliv3r> the 'pflege' starts at 01.07.2013 and runs till 01.07.2014
<oliv3r> it's legit
<Turl> sounds like scam to me :D
<oliv3r> you get a link to tsc.denic.de with login information to change settings
<Turl> esp. when domains are like 1/5 of the bill :p
<oliv3r> no, what happened is, when my-domainnickname.de went bankrot, denic claimed the domains
<oliv3r> and offered you a years time to re-register them whever youw anted
<oliv3r> you got access to the auth key and everything
<Turl> pflege means maintenance apparently
<oliv3r> i did that (in april) so its hosted elsewhere now
<oliv3r> it sounds that there admin is lazy and hasent noticed it moved or something
<Turl> mail them then :)
<oliv3r> (automated system :p)
<rellla> can't help, as i never had to do with denic themselves... maybe denic does not know, that it's hosted again
<oliv3r> i allready did
<oliv3r> i think it's an automated message that got sent on the 1st of july
<oliv3r> the bill is dated july 1st
<rellla> i cancelled 2 domains last year, they went into some domain parking-"let me make some money with doing nothing"-system
<buZz> they should make those illegal
<atiti> hey guys, i got a question about this libve stuff
<rellla> ask
<atiti> im feeding h264 NALUs to libve_decode
<oliv3r> rellla: that's exactly what this is imo
<oliv3r> what's a nalu? :)
<atiti> and it seem to accept them fine as the return code is VRESULT_OK
<atiti> but it never returns the VRESULT_FRAME_DECODED or VRESULT_KEYFRAME_DECODED
<atiti> which I guess is what I need to get the decoded frame
<atiti> oliv3r: network abstraction layer unit
<oliv3r> ah ok
<rellla> so where is your code?
<atiti> basically an h264 slice formatted for the network
<atiti> right now its somewhat hacky, so plz disregard the mess :p
<atiti> video_decoder_x264_dec_image receives the raw NALU in annex-b format
<atiti> strips away the start code (00 00 00 01)
<atiti> and feeds the rest into libcedarx
<atiti> libcedarx_decoder_add_stream returns 0, libcedarx_decoder_decode_stream(1) returns 0, libcedarx_decoder_request_frame() returns NULL
<rellla> which libcedarx do you use?
<atiti> willswang one
<atiti> i used the vlc implementation as a reference
<atiti> (also by him)
hipboi has quit [Remote host closed the connection]
<rellla> don't know when libve is returning VRESULT_OK or VRESULT_FRAME_DECODED. At least you are in the right switch case ;)
<atiti> hehe thats true
<atiti> it seems like it never wants to return anything else then VRESULT_OK
<atiti> but then i'm not exactly sure how to get the frame out in the correct way yet
<atiti> at least all those callbacks (request_buffer, update_buffer, release_buffer, etc) are never called!
arete74 has quit [Ping timeout: 240 seconds]
<rellla> ?
<atiti> not sure, I guess what that returns is a handle to the decoded pic?
<atiti> or at least what it should return in my eyes, what it actually returns is just NULL
<atiti> hm ye, ill do a quick check on where that comes from
eebrah has joined #linux-sunxi
<atiti> heh, it comes from libcedarx_decoder_request_frame
<atiti> then !decoder || !decoder->fbm
<atiti> hm
<atiti> is libve responsible for init-ing the fbm?
* atiti reading the libve user guide
<rellla> it is imo

<atiti> hm
<atiti> actually it seems my vlc doesnt work with cedar either
<atiti> [0xb6808a68] main video output error: pictures leaked, trying to workaround
<atiti> at least the output doesnt work
<hramrach__> there are issues
<hramrach__> some media does not work well
<hramrach__> and hard to tell if it's broken or what
<hramrach__> still breaking the decoder on broken media is also broken
<atiti> :(
<hramrach__> which media file
<hramrach__> did not see this bug yet
<atiti> hm another file decodes
<atiti> just doesnt display
<rellla> btw this one i had very often, too: [DISP] not supported image0 pixel sequence:59 in img_sw_para_to_reg - but could not reproduce/ investigate
<rellla> just spams log and decoding/rendering gets laggy
<hramrach__> rellla: that happens when a player crashes or fails to decode
<rellla> ah. so after a failed playback, spamming starts. but how to stop it?
<rellla> and how to prevent?
<atiti> its not a decode problem
<hramrach__> I suspect that it does not tear down something properly and the kernel driver is not clever enough to tear down the decode jobs when the player goes away
<atiti> the libve_decode returns 2-3
<atiti> meaning it decodes normal or keyframes
<hramrach__> when you start playback of some working media file it usually goes away
<hramrach__> btw the sintel trailer plays back all right here
<atiti> weird
<atiti> nope, Sintel still doesnt play
<atiti> with the "pictures leaked" error
<atiti> and Shrinkage doesn't display
<rellla> atiti: a kernel/disp/script.bin problem?
<atiti> could be
<atiti> running 3.4.43.sun5i+

<wingrime> mripard: ping
<oliv3r> hey wingrime
<oliv3r> anything i can help with
<mripard> wingrime: hi
<hramrach__> user_2: I don't know how so. I can check out the repo just fine
<wingrime> oliv3r: you can help with axp202 wiki page fix
<wingrime> oliv3r:please form internal register table from text
<wingrime> mripard: what I need write to of_device_id
<wingrime> in compatible
<hramrach__> atiti: if it plays and does not display try to shrink the console with fbset or something. some people reported issues with video playin below the console layer
<mripard> wingrime: usually, it's company,device
<mripard> so it would be x-powers,axp202
<mripard> I guess
<mripard> (if that was your question)
<wingrime> it actualy not all
<atiti> hramrach__: actually my main problem is that the decoding seem to work fine for a given h264 using vlc, but when I try to feed my own h264 data to libcedarx in my own application, then the the decoder alway returns VRESULT_OK, and there is no output frames
<atiti> and apparently the FBM is not initialized by the decoder
<atiti> so im a bit stuck on how to debug it :/
<wingrime> mripard: axp are complex device, so can I define many module_platform_driver()
<hramrach__> atiti: there is some doc on libvecore somewhere (hopefully dl.linux-sunxi.org)
<hramrach__> also if it works in vlc it does something different
<atiti> ive been reading the Libve User Guide, but its a bit vague
<hramrach__> you can try like running it in debugger or try to reusing the vlc plugin
<atiti> im going to try to rig the libcedarx to write the raw data it feeds libve out to a file
<atiti> and compare what vlc does
<mripard> wingrime: I'd expect more to have a single driver, and during the probe register to several frameworks
<hramrach__> atiti: note there are two plugins - one decode, one disp
<hramrach__> you can feed the raw data to somewhere they would get displayed
<hramrach__> like there used to be image viewers for framebuffer console
<atiti> hramrach__: yea, I'm focusing on the decoder for now, then once thats working, disp is the next target ;)
<hramrach__> so you would have some idea what you get from cedar even if the colours are wrong
<wingrime> mripard: you mean I need register single platform driver (simple platform driver) , than in probe ,register i2c, battery,input ?
<wingrime> simply it a frist time I deal with multi-framework
<mripard> wingrime: yep, precisely
<mripard> again, this is pretty much what we're doing with the pinctrl driver
<mripard> we register it a gpio, pinctrl and interrupt controllers
<wingrime> mripard: I will take a look
<wingrime> mripard: why you use dev_info not pr_info , it does mater?
<mripard> you should use dev_info whenever you have access to a relevant device structure
<mripard> pr_info is here for when you aren't in such case
<wingrime> it add driver name to string ?
<mripard> yes, driver name, instance, and so forth
rellla2 has joined #linux-sunxi
rellla2 has quit [Ping timeout: 260 seconds]
<wingrime> mripard: how activate debug/info with pr/dev prints ?

user_2 has quit [Ping timeout: 260 seconds]
user_2 has joined #linux-sunxi
<wingrime> how enable it for single driver
rellla2 has quit [Ping timeout: 260 seconds]
<mripard> pr_info is logged but not shown unless you modify loglevel
<mripard> usually through the commandline
<mripard> pr_debug is a noop by default
<mripard> you have to pass -DDEBUG at compile time to have it
<wingrime> there is way pass it only for one module?
<wingrime> i will add Makefile/Kconfig and do make
<wingrime> as ususaly
<mripard> in your driver makefile, add ccflags-y := -DDEBUG

<wingrime> I don't know will that joinment aproved
<Turl> wingrime: are you writing mfd driver?
<wingrime> Turl: now power
<wingrime> I mean axp have many functions
<Turl> mfd means multi function device, might be good if you intend to register as lots of stuff :)
<wingrime> Turl: it have gpio+timer+ldo+pwm+batterycontrol+powerbutton
<Turl> wingrime: look in drivers/mfd, you will see many PMICs
<wingrime> Turl: you mean it must go to /mtd/ folder?
<Turl> mfd, not mtd

<Turl> check the console output and make sure it says mali like on the wiki
<user_2> test report: vendor ARM, renderer mali 400 MP, version opneLG ES 2.0
<user_2> yes, it is similar to "success" case on wiki page.
<Turl> ok then, that's working right and apparently sunxifb too
<Turl> did you enable G2D?
<user_2> well, but i wish a gles application to see how mych smooth it is... suggestion?
<user_2> some game, maybe?
<Turl> Qt Cinematic Experience
<Turl> ssvb: any better suggestions for a GLES app? ^
<ssvb> glmark2-es2 is the most "advanced" demo I'm aware of
<user_2> some packages avaiable in apt-get? im running debian, so it is ok 4 me tu use apt-get :-)
<Turl> user_2: I don't know really :) I run all my sunxi devices headless or with android
<Turl> I know they use that one on demos and such
<user_2> ah... you are on the "other side of the river" :-)
<user_2> let me see.
<oliv3r> wingrime: axp as your first driver, a daunting task, the pmic is full of features, could take you months! but I applaud and welcome your effort :D
<Turl> oliv3r: you're not being exactly supportive lol :P
<user_2> mmm flid video
<user_2> fluid
<oliv3r> Turl: i'd start with something smaller to begin with :)
<ssvb> user_2: you can try "apt-get install glmark2-es2" and then run it
<user_2> ssvb, tnks!
<user_2> i do immediately
<Turl> user_2: btw, if you're using 1080p, it might be better to switch to 720p
<user_2> im alreadi in 720
<Turl> ok then :)
<oliv3r> Turl: then again, you don't have to implement everything at first, only bare essentials
<oliv3r> Turl: and is dlan pouching our devs? :p
<Turl> ssvb: that's something that could be added to the wiki :P
<Turl> oliv3r: who? :p

<user_2> glmark not exixt, ssvb
<oliv3r> Turl: didn't you backread?
<Turl> oliv3r: I've been in here for quite a while :p probably read it and forgot
<oliv3r> Turl: dlan asked for experienced kernel developers for (payed) work
<ssvb> user_2: indeed, glmark is packaged for ubuntu, but not for debian
<user_2> yes.. the hell, i have the driver but notapplication to run with :-(
n01 has joined #linux-sunxi
<ssvb> user_2: as for the games, I'm not sure what to recommend, it does not look like we have much to select from - http://www.cubieforums.com/index.php/topic,444.msg1991.html
<ssvb> user_2: yes, OpenGL ES happens to be mostly useless in Linux at the moment
<Turl> oliv3r: oh, I recall now
<ssvb> user_2: but you can run a compositing window manager like gnome-shell or kwin-gles for some desktop effects
<Turl> oliv3r: btw, I laughed the other day when I saw your free electrons joke lol
<user_2> ok
<user_2> i see there is xscreensaver-gl, so i can istall an see it working. at least to test the system.
<oliv3r> Turl: i'm not sure others got it
<ssvb> user_2: or build Qt5 with GLES support and try some of its demos
<user_2> let me test xscreensaver-gl for them oment.
<ssvb> user_2: many "gl" applications require desktop Open GL, which can't be accelerated
<user_2> ssvb, i dont nderstan te meaning of ""user_2: many "gl" applications require desktop Open GL, which can't be accelerated
<ssvb> user_2: http://en.wikipedia.org/wiki/OpenGL_ES - "OpenGL for Embedded Systems (OpenGL ES) is a subset of the OpenGL 3D graphics application programming interface (API) designed for embedded systems"
<ssvb> user_2: if your application wants the real OpenGL, you are out of luck
<user_2> ah, ok. yes i know applicatuons MUST be recompiled fot GLES, a subset of "real" GL.
<user_2> screensaver "superquadratics" is nice, openGL ES works well
<ssvb> user_2: the applications need to be ported to GLES, and here is some interesting rant about xscreensaver-gl - http://www.jwz.org/blog/2012/06/i-have-ported-xscreensaver-to-the-iphone/
<ssvb> user_2: nice, does it use the hardware acceleration?
<user_2> ssvb, how can i see if use hard accell or not?
<user_2> i can tell it is not "smooth and silk", it seemt to go as "tic-tac-tic-tac" and not in fluid mode.
<user_2> so i sulspect is nto accellerated by hardware
_BJFreeman has joined #linux-sunxi
<user_2> ssvb, i see indicator of cpu was more than 70% during scrennsaver demo, so i suspect no hardware accelleration woas activated.
<user_2> how can i activate adrware accelleration?
_BJFreeman is now known as BJfreeman
<user_2> mmmm xscrensaver-gl is GL, not openGL, not openGL ES, so i think it is useless to use it as test.
<user_2> well, about video: gnome-mplayer run ok, but it cannot scale to fullscreen the movie. totem can scale to fullscreen the movie but i miss many frames and it is "slow". there is a way to sole the situation ad have movies running fluid at fullscreen?
<ssvb> user_2: seems like this is getting really popular - https://github.com/ssvb/xf86-video-sunxifb/issues/4 :)
<user_2> i look ait it now
<ssvb> user_2: also for hardware accelerated video decoding you can try http://linux-sunxi.org/VLC or http://linux-sunxi.org/XBMC
<ssvb> user_2: I think that's the only way to watch 1080p movies
<user_2> XBMC i tried couple of weeks ago. after all job, xbmc wils fluid, but colors was all falsed, all "shifterd" to blue :-(
<user_2> wils=was
<user_2> 2D, 3D, video decodin... all important topics, but apparently it is not well considerated and supported by community. i talk about linix side.
<user_2> linux*
<ssvb> user_2: you can't get much better 2D performance, but you already should not have many problems with it either
<ssvb> user_2: (video scaling in mplayer is a separate matter)
<user_2> separate matter?

<ssvb> 2D is graphics, and mplayer is video
<user_2> ok

<user_2> but, as i said, xbmc didt give me sutisfation, under color viewpoint.
<ssvb> yes, I think that I should fix scaling in mplayer right NOW
<ssvb> you can try VLC, it does not have these color problems
steev has joined #linux-sunxi
<ssvb> and the color problem in XBMC can be workarounded by starting XBMC, exiting from it and restarting again
<ssvb> something is obviously wrong, maybe rellla can fix it some day

<user_2> ssvb, solve the color issue in xbmc is STRONGLY appreciated, it will be the "final" activity to complete mycubieboard installation.

<A70X> Hi, anybody know of a wiki/README that shows how to generate LiveSuite images from nand[a-j] images I grabbed using adb?
<A70X> I got a new A70x Allwinner A20 tablet and I'd like to back up what I've got before I start hacking away
n01 has quit [Ping timeout: 264 seconds]
<oliv3r> A70X: if your manufacturer doesn't over an image, i guess you can try making your own :)
<oliv3r> A70X: but a10 chips are nearly unbrickable
<oliv3r> your best backup, is to get a 3+ GB Sd card, and put hansg's fedora 18 image on it
yo5phz has quit [Read error: Connection reset by peer]
yo5phz has joined #linux-sunxi
<A70X> I don't have a manufacturer image, but I've got adb root, so I can grab /dev/block/nand[a-j] images with adb pull
<A70X> It's all there: nanda got a vfat fs with script.bin, u-boot etc
yo5phz has quit [Read error: Connection reset by peer]
yo5phz has joined #linux-sunxi
<A70X> I know I'm supposed to work with SD images only, but I'd like to know I can rescue my nand if the shit hits the fan
<oliv3r> yep, you can always dd partions back/forth
<oliv3r> hence you want a usable sd card to do tha
<A70X> The reason I'd like to use LiveSuit is because the A20 support is still WIP, and LiveSuit should be able to recover my nand, even without a working linux kernel, right?

<A70X> The wiki talks about boot0 and boot1 bootloaders, but I can't find these in the A20 nand partitions.
dragonn has quit [Ping timeout: 264 seconds]
<A70X> Here's what the A20 nand images look like:
<A70X> nanda-bootloader.img: x86 boot sector, code offset 0x0, OEM-ID " ", sectors/cluster 4, root entries 512, Media descriptor 0xf8, sectors/FAT 256, sectors 262144 (volumes > 32 MB) , dos < 4.0 BootSector (0x0), FAT (16 bit)

<A70X> Sorry, I'll use that in future
<Dreadlish> it doesnt look good to put a big amount of text here
<Dreadlish> files which are you looking for are probably on nanda
<Dreadlish> if not - try to extract them from nandc
<Dreadlish> i can't help you more.
<A70X> I guess my question boils down to: Is it a simple process to reverse nand images back to a Livesuit image
<A70X> Looks like this might be what I'm after: http://linux-sunxi.org/Boot_Android_from_SdCard
