<wens> Yes
<wens> wait
<wens> only vsync/hsync from LCD1
<wens> most of the GPIO pins for stuff like mmc card detect and regulators are using LCD1 pins
<Net147> so can I drive the HDMI and LCD separately at different resolutions with different graphics?

<rm> which OS
<JohnDoe_71Rus> debian 3.4.75+ patwood
<rm> in Android, probably; in GNU/Linux you can use pretty much any resolution
<rm> e.g. I use 1680x1050 and 1280x1024 over HDMI
<JohnDoe_71Rus> i try 1024x768. [DISP] Unsupported mode: 1024x768p60, ignoring
<rm> maybe you need to ensure EDID worked fine first
<rm> try the uEnv.txt as suggested in the 1st reply
<JohnDoe_71Rus> No valid EDID mode found :( thanks

<gzamboni> morning
<gzamboni> i talked with the mozilla guys at fosdem and i asked if the mozilla os was android based or not
<gzamboni> they said they used the linux kernel that was made for the android and that the mozilla os is not based on the android os.
<gzamboni> they said also that they failed to use the A13 with the mozillaos
<gzamboni> so now they are using an A31 wich apparently they got the drivers code from a cyanomodgen project
Guest45382 is now known as Wizzup

<gzamboni> they were in the same building of you talk and they didnt seem to be "aware" of the sunxi project
<gzamboni> i should have talked with them before the talk and should have invited them to come see your speech
<Philippe_Fouquet> oliv3r : you know where I can find exemple ?
<oliv3r> gzamboni: yeah; a little sad really; to work with allwinner hardware, and not be aware of linux-sunxi
<oliv3r> gzamboni: or worse, i mean, i made my title pretty obvious 'allwinner' was in the name
FR^2 has joined #linux-sunxi
<oliv3r> just shows the involvment really

<oliv3r> i'm supprised they didn't even bother to check the schedule

techn_ has quit [Ping timeout: 265 seconds]
<Philippe_Fouquet> oliv3r : Ok thank for your reply
<mripard> gzamboni: I'm not sure that would have changed anything actually
<mripard> oliv3r was pretty clear about the fact that linux-sunxi doesn't care about the A31
<gzamboni> dont know, as they tried out the A13 before, maybe the A20 could interest them
<gzamboni> i will just join their irc server /channel and leave a msg, hey, i heard you are working with allwinner chips for the mozilla os, im from the sunxi comunity if you need some help you can join us at #linux-sunxi at freenode
<oliv3r> gzamboni: i dont' understand how 'a13 doesn't work'
<oliv3r> maybe with allwinner stuff
<gzamboni> i dont know the sources they used
<oliv3r> mripard: you make it sound like i was being harsh!
<oliv3r> gzamboni: excellent :)
<gzamboni> mripard, later today i will clean up my dt work on the dma code and send you
<oliv3r> i know someone ported it to a20 qallready
<mripard> oliv3r: you were pretty blunt about it...
<oliv3r> mripard: i was wasn't I :(
<mripard> gzamboni: cool, I was going to ask you :)
<oliv3r> taking the a31 tree; and getting it to run on a20 should be pretty easy imo

<ccaione> ansi :) cannot stand the ISO layout
<mnemoc> after some years using a das keyboard without labels and strugling to realign my hands every time i get distracted, I love that the ninja has those "hidden" labels
<JohnDoe71rus> keyboard for touch-typing?
<mnemoc> the brown switches are like in the middle... you don't need to press them much for them to react
<mnemoc> blue switches require hammering
<ccaione> I learnt to touch-typing after switching to dvorak
<mnemoc> but they feel equality touchy
<ccaione> touch-typing == typing without looking at the kb
<mnemoc> oh...
<mnemoc> i was talking about the feeling of typing
<oliv3r> Turl: strange; i got a first draft back from packt that needs some work
<mnemoc> i assume no programmer looks at the kb when typing

<binaryferret> Not fully related to sunxi, but I'm attempting to get touch screen working with an A13 device and I'm using a driver for the gslx680. In order to build it I need to edit the MakeFile and change a variable to the build folder of my kernel. However I'm not sure which folder this is in the linux-sunxi tree.
<binaryferret> Wait I think I was being stupid and just had to point it at the linux-sunxi folder...durr

<oliv3r> libv: i'm studying the olimex LIME design, and i notice HDMI is having its own dedicated pins? does that mean HDMI + LCD0 is possible without problem?
<wens> oliv3r: HDMI always had it's own pins
<oliv3r> on luc's slide, he mentions there's 2 LCDC's and HDMI is connected to LCDC0
<wens> the issue, as stated by libv, is that HDMI and LCD0 share the same display engine
<oliv3r> in KMS speak, it would have been CRTC0 really
<oliv3r> exactly
<oliv3r> so how can olimex show LCD + hdmi on their boards; when the LCD is wired to LCD0
<wens> did they show different output?
<mnemoc> wens: yes
<oliv3r> mnemoc: you lurker!
<mnemoc> :p
<mnemoc> video + android
<mnemoc> s/video/movie/
<mnemoc> maybe using different parts of the buffer?
<Turl> its mostly about the res/mode rather than content I think
<wens> don't think that's possible
<wens> the HDMI controller takes LCD data/sync lines for the video
<Turl> oliv3r, check your inbox

<Turl> is the yellow leaky thing on the inductorish thing normal?
<oliv3r> Turl: yeah
<oliv3r> that's hot glue, to keep it from resonating
<oliv3r> the LAN port got fried and took the rest down
<Turl> you mean wan (blue)?
<Turl> pcb traces on there look burnes
<Turl> d
<Turl> I think it also took down the GbE port on my mobo :/

<libv> yw, and i really do this because i love doing this, it's great to be part of this insane thing called fosdem
<oliv3r> libv: why so much power!
<libv> organizers believe they had around 10k visitors
<oliv3r> most of the cables you carry is power
<binaryferret> I've put the gslx680.fw firmware file in lib/firmware, but when I modprobe gslx680_ts it falls over when it tries to open firmware gslx680.fw. I tried renaming the file to something random and got the same message so it's leading me to believe that it can't find it. Has anyone gone through getting the gslx680 driver working on a A13 tablet?
<libv> oliv3r: yes?
<libv> oliv3r: 200 folk devroom?
<binaryferret> I've used the driver available from https://gitorious.org/gslx680-for-sunxi

<oliv3r> libv: you supplied them all with power!
<libv> i think i had 4 of those bars already for my first devroom in 2006
<libv> and they saw very very very heavy usage
<libv> now i think people have longer lasting hw, and perhaps don't see the powerbars as easily
<libv> but they do see quite some usage, and you see some people flocking around them

<nove> a crazy idea, there is android, firefoxos, sailfishos, tizen, plasma active, the ubuntu mobile thing
<oliv3r> they are all potential users
<oliv3r> we need some distro hackers though; to get us nice images
<nove> all use the linux kernel, and similar userland libraries
<oliv3r> similar enough yeah
<nove> why isn't possible to do, apt-get install android
Net147 has quit [Quit: HydraIRC -> http://www.hydrairc.com <- Now with extra fish!]

<oliv3r> or whatever their disp driver is called
<oliv3r> nove: but think even easier
<oliv3r> android = apk run by davlik/art engine, right?
<oliv3r> so basically it's just dalvik -jar app.jar
<oliv3r> why can't I run an APK using dalvik on my desktop?
<oliv3r> (disp driver again)
<nove> no not under X, instead of start X, it would be started surfaceflinger (if that is the thing)
<leviathanch> wens: yes, I'm using mmc_of_parse
<oliv3r> nove: that shouldn't be a huge problem
<oliv3r> nove: since there is x86 android
<leviathanch> this way I can drop some homebrew functions and rely on the other kernel maintainers for my GPIO handling :-)
<leviathanch> wens: that's why I urge people to accelerate their upstreaming support
<nove> oliv3r: i thing so, and it would be better that dual boot
<oliv3r> nove: just needs a hacker to do the heavy lifting
<oliv3r> nove: but at the very least; you should be able to run it in a chroot no?
<nove> oliv3r: yes, but here the key would be to integrate in the distribution, so that a simple apt-get install, made it work
<oliv3r> even if it where a chroot env; should still be possible :)
<oliv3r> emerge android! :p
<oliv3r> i don't know why nobody made it happen yet; nobody cares?
<oliv3r> just like we don't have a community android either
<mripard> oliv3r: nove: Android uses a different libc, a different init system, dalvik as more of a daemon, etc.
<mripard> it's not impossible
<mripard> but it would be very hard to achive.
<nove> mripard: we have the source, but yes
<oliv3r> so wont' work in a chroot?
<oliv3r> libv, init etc all would work in the chroot nativily i'd expect?
<mripard> oliv3r: chroot doesn't start a brand new init
<mripard> it might work in a container though
<oliv3r> for starters
<nove> mripard: the previous init would be stopped, and new started
<oliv3r> but, ok, android is bionic etc, won't it be possible to recompile dalvik to simply use libv?
<oliv3r> nove: might aswell reboot then :p
<mripard> nove: you can't stop init.
<mripard> it's an instant panic
<mripard> oliv3r: what's libv ?
<mripard> (except libv)
<nove> glibc maybe
<oliv3r> libc :p
<oliv3r> yes, libv and libc are very confusing
<mripard> ah
<mripard> well, you'd need to implement bionic-specific functions into the glibc I guess
<oliv3r> i mean, bionic and libc are the same API are they not? they are not abi compatible, but API they are?
<mripard> nope
<oliv3r> oh there are bionic-specifics
<oliv3r> anyhting you know from the top of your head?
<mripard> bionic doesn't even implement full POSIX

<nove> what about binfmt_misc, can be made to detect bionic linked binaries, and use the right loader
<mripard> actually, the loader isn't much of an issue
<mripard> you can have a glibc and android side by side, and it will work pretty fine
<oliv3r> define android
<oliv3r> androis is the entire system
<oliv3r> but does an apk need android, or is dalvik enough :)
<oliv3r> not that android is much more (or less I guess)
<mripard> android is a full java framework, underlying daemons, and dalvik, mostly
<mripard> if one of these aren't there, you won't be able to run any apk
<mripard> plus, the usual kernel stuff: binder, ION, ADF and their friends
<oliv3r> i thought that dalvik was the java framework
<mripard> no, dalvik is just the vm
<nove> and that can't be set as a init service, so to be possible to do service start/stop
<oliv3r> but it's apk -> dalvik -< all the gutsy stuff
<nove> service android start/stop, and alike
<mripard> you could have an apk that doesn't use dalvik at all

<mripard> if it's all native stuff
<mripard> nove: Android's init is very specific too
<Turl> you could run android on lxc
<Turl> some do I think
<nove> same thing with firefoxos, is only the b2g process and some demons which interface the hardware
<mripard> Turl: yep, that was my first solution :)
<nove> well the base of the idea, is to put everything in the same box
Fusing has joined #linux-sunxi
<Turl> second solution xould be normal android
<Turl> with chrootish linux
<nove> by been split has is now, i can't see a very good future
<Turl> maybe with user systemd
<plaes> is user systemd actually possible?
<nove> then it was the user that makes the choice of which one to run
<Turl> plaes, I have seen it mentioned around
<mripard> Turl: systemd lacks several android features, you can't use it instead
<Turl> not instead, but as 'subinit'
<mripard> but chroot doesn't run anything but the shell iirc
<Turl> isnt syatemd user mode forbthat?
<Turl> fuu kbrd

<oliv3r> isn't team-hacksung working on exynos*
<plaes> didn't they give up?
<plaes> can't even find them via google
<oliv3r> /j #team-hacksung
<libv> androiders...
<libv> there are probably some good people
<libv> there
<oliv3r> aren't they also hacking the tv's?
<libv> but it's probably stuck in the forum marsh
<oliv3r> i guess because it works quite well; there's little community
<oliv3r> i did hear from paulk-collins_ that some of the stuff isn't upstreamed at all though
<oliv3r> oh radeon UVD Video encoder opensourced
<oliv3r> openMax based
<paulk-collins_> teamhacksung mostly gave up
<paulk-collins_> and because of the split between CyanogenMod and OmniROM, things are even messier
<oliv3r> :(
<oliv3r> sad, really sda
<paulk-collins_> codeworks was kind of coordinating the effort, but AFAIK they stopped porting to new exynos targets
<paulk-collins_> they mostly maintain the already supported ones
<oliv3r> out of curiosity, what is mainlined and what is missing on exynos 4412
<oliv3r> i know sensor(s/hub)
<paulk-collins_> I suppose most of the board files for the actual devices are missing
<paulk-collins_> probably only a few EVBs there
<paulk-collins_> (in mainline)
* mnemoc look at his exynos 5420 tablet with sadness
<paulk-collins_> nexus 10?
<oliv3r> but code wise
<paulk-collins_> oliv3r, to be honest, I didn't really look at it, but I'm not aware of anyone using mainline on the actual devices
<mnemoc> paulk-collins_: galaxy note 10.1" 2014 wifi
<paulk-collins_> oh yeah
<paulk-collins_> oliv3r, I know Samsung have people working on mainline
<paulk-collins_> for exynos and related things
<plaes> for tv-s?
<paulk-collins_> clearly separate from the ones working on Exynos support for Android kernels
<paulk-collins_> not sure at all
<oliv3r> well i know mauro from linux-media started to work there; i follow the linux-media list and see a lot of samsung patches
<HdkR> N10 is the 5250, note 10.1 2014 is 5420 :P
<oliv3r> and samsung is hiring linux devs like crazy
<paulk-collins_> yes indeed
<paulk-collins_> they do that
<oliv3r> so there is some hope
<oliv3r> i do have the impression samsung would slowly move more towards mainline
<oliv3r> they do seem to get it, atleast a little
<oliv3r> or so it seems
<paulk-collins_> right, but I'm not sure they ship products that actually use it
<oliv3r> oh i doubt that; that'll be years from now i guess :)
<oliv3r> how brick-proof is exynos4412?
<paulk-collins_> also, a few years ago, someone started an effort to cleanup the galaxy s2 (exynos4) kernel code in a mainline-compliant approach
<oliv3r> can you recover from mmc easily? or do you always depend on the bootloader in nand working
<paulk-collins_> AFAIK it did boot but didn't work well at all, and he kid of gave up
<oliv3r> sad :(
<paulk-collins_> oliv3r, it's not brick-proof
<paulk-collins_> basically as long as you don't touch at the bootloaders, you should be fine
<paulk-collins_> but boot order is probably set in stone through resistors
<oliv3r> what about uart?
<paulk-collins_> and UART/MCC are not first
<paulk-collins_> it's like NAND-first
<oliv3r> can you connect uart to debug?
<paulk-collins_> yes
<paulk-collins_> easily
<oliv3r> eMMC i assume :)
<oliv3r> ok good; that's really good
<paulk-collins_> right
<oliv3r> note 2 uart?
<paulk-collins_> basically UART is through the micro USB connector
<paulk-collins_> didn't check, but should work
<paulk-collins_> I can test right now actually
<plaes> hm
<oliv3r> gadget uart?
<plaes> all samsungs have powervr?
<paulk-collins_> oliv3r, there is a hardware switch
<paulk-collins_> oliv3r, basically, you trigger UART through a particular resistor value between ID and GND
<paulk-collins_> so it's real uart
<oliv3r> i'm reading it now
<oliv3r> ah that's amazing
<oliv3r> awesome
<plaes> link?
<oliv3r> i did read it doesn't work on sii and siii
<oliv3r> i should make me a cable for that
<oliv3r> ah better :)
<paulk-collins_> yeah, works on note2
<paulk-collins_> got bootloader output
<oliv3r> awesome
<paulk-collins_> you can get dmesg quite easily too
shineworld has joined #linux-sunxi
<oliv3r> this should make it huge amounts easier to recover from a 'brick' on nand though
<oliv3r> if you can upload code over uart to fix stuff that is
<paulk-collins_> that's a first step
<paulk-collins_> basically, this happened:
shineworld has left #linux-sunxi [#linux-sunxi]
<paulk-collins_> * GNUtoo modified 1 byte on the nexus s bootloader's partition
<paulk-collins_> * the bootrom checked the signature, it didn't match, it stopped
<paulk-collins_> * nand was first so it didn't try UART
<paulk-collins_> * GNUtoo had to move around resistors to change the boot order to UART first
<paulk-collins_> * then he sent a signed bootloader through UART and it booted
<oliv3r> boot uart first? wow; didn't even know that was possible
<oliv3r> a signed bootloader extracted from a nother device I assume
<paulk-collins_> well if you move the resistors correctly, it can, or at least it was before NAND
Black_Horseman has joined #linux-sunxi
Black_Horseman has joined #linux-sunxi
<oliv3r> atleast it's technically possible modify the resistors
<paulk-collins_> oliv3r, Google thankfully distribute the binaries for nexus phones
<oliv3r> but what i'm really only after, changing kernels, see why things go wrong etc
<paulk-collins_> oliv3r, yeah but they're real tiny, it's impossible without a lense
<oliv3r> so serial + stock bootloader should be fine
<paulk-collins_> yes that'll work :)
<oliv3r> yeah you need a horribly steady hand :)
<paulk-collins_> that too
* paulk-collins_ already damaged a phone while soldering on it
<paulk-collins_> I'll go for a moment, bbl
<plaes> damn.. I'm really thankful for Allwinners ease of hacking..
