<Lumocolor> with the cubieboard, Can I have debian install with only free software packages installed, no non-free drivers, firmware fat blobs?
<mmarker> A10? It's Mali if I recall. I think the biggest thing you lose is the hw codec acceleration. But even that has a open source project around it - check the wiki.
<mmarker> But I'm somewhat new to sunxi. Others here can tell me if I'm full of it.

<Lumocolor> Turl: great, I assume this is not an chroot and do I download the installer from the debian website?

<Lumocolor> or do I need to build it?
<Lumocolor> thanks btw

<Turl> Lumocolor: you can get a premade image from someone, or follow https://linux-sunxi.org/Manual_build_howto and use a debian rootfs from someone/debootstrap your own with help of qemu on your x86 box
<Turl> rm has a debian rootfs on his site iirc
<Lumocolor> whos rm>
<Lumocolor> I see
<Lumocolor> arr ok I have to /msg him ok
<Turl> Lumocolor: just check out his site, https://romanrm.net/
<syeekick> hey my tmux session over ssh is a little pokey and slow. Will installing drivers for the cubie truck improve these problems?
<Lumocolor> Turl: so a hell of a lot of compiling? no hugh pre-built repo?
<cosm> Lumacolor: (of course) there are official debian repositories for arm
<cosm> Lumacolor: although I'm not sure what's the status of their armhf port
<cosm> Lumacolor: apparently it's all good https://www.debian.org/ports/#portlist-released
<Lumocolor> oh so armhf is compatable...? that makes it easier
<Lumocolor> It's just I'm thinking of getting a small a20 vubieboard while I am waiting for my improv http://makeplaylive.com
<cosm> Lumocolor: sorry, I've noticed I've misspelled your nickname above
<Lumocolor> right bed time for me
<Lumocolor> cosm: np
<cosm> Lumocolor: yes, in general you should be able to just run a standard armhf build for whatever distribution
<Lumocolor> great
<cosm> Lumocolor: you'll need a kernel specific to your hardware
<Lumocolor> ok

<TuxboxGuru> s/little/no
<TuxboxGuru> :-P
<megal0maniac_afk> TuxboxGuru: Well... they did install it :P
<TuxboxGuru> hahahahahaha... I do give you that much, most probably based on a Wiki page someone else wrote :D
deasy has joined #linux-sunxi
<megal0maniac_afk> I'm battling with an Android image which has the mount points all wrong. If you try and install any app that needs additional storage, it can't use the SD card. That mount might be mapped to SATA, I haven't checked that yet, but you'd think SD would be default...
<TuxboxGuru> You would think that... but its not the case - some apps have the 'Use External' flag in the manifest .. those have external storage enabled
<TuxboxGuru> I think there is a mod to the Android system to default the install to external devices
<TuxboxGuru> (Android not my flavour... just quoting some experiences)
<megal0maniac_afk> TuxboxGuru: There is, but it doesn't work here
<megal0maniac_afk> There is an fstab file though, but it's r/o even as root so I gave up. It's A20 so simply booting Linux will trash the Android install anyway
<megal0maniac_afk> Still haven't settled on a preferred A20 distro
<megal0maniac_afk> Although Cubieez is up there

<TuxboxGuru> Cubian has a ton of junk installed on the BASE though (stunne4 and some web admin)
<TuxboxGuru> once all deleted, its not bad
<blsd> pq: it's me again (the guy building weston/wayland on cubietruck) - you mentioned something yesterday about running only on /dev/fb device - in this case does weston require EGL + GLES?
<megal0maniac_afk> TuxboxGuru: Thanks, I'll have to try it again. Couldn't get decent video playback on cubieez and I'm a complete n00b with CedarX/Mali stuff so I haven't attempted to change anything :)
<TuxboxGuru> megal0maniac_afk: ah! .. you didnt mention video :D .. I am yet to cross that bridge as I want to make a PVR type system
<TuxboxGuru> MPEG2/4 decoders and Encoders
<linkmauve1> blsd, the fbdev backend of Weston isn’t GL-accelerated AFAIK.
<shineworld> megal0maniac_afk, what board and android image are you using ?
<linkmauve1> It’s purely software-rendered, just like the pixman backend.
nabblet has quit [Quit: leaving]
<TuxboxGuru> the fbdev is not GL accelerated - but it could have blitter/compositor accelerations for rendering....
<TuxboxGuru> GL is first prize though
<blsd> ok, thanks guys
<blsd> trying it out now
<blsd> as I understand there is no support for wayland/weston right now on cubietruck, right
<blsd> ?

<ssvb> blsd: for wayland specific egl bits you can use the libhybris wrapper
<blsd> you mean use android's drivers?
<ssvb> yes
<blsd> ssvb: ok thanks :)
<ssvb> my understanding is that the normal mali egl drivers for the framebuffer and x11 do not support https://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_platform_wayland.txt
<blsd> I will try first to run wayland/weston on /dev/fb first to gain some experience and then I'll move onto acceleration support
<blsd> ssvb: yes, correct
<ssvb> libhybris is the roundabout way of getting egl/gles, but they must have handled the wayland extension somehow :)

<TuxboxGuru> Anyone got an idea on how far CedarX reverse engineering is going ?
<vector80> oh my god, sorry for delay
<vector80> I am now trying to tune my system for both android and linux
<vector80> ssvb, firstly, let me ask like this: In android, we can modify Dram Clk via sys_config.fex, however in linux, we have to statically set it in the board/sunxi/dram_myboard.c file ?
<vector80> Is that correct ?
<TuxboxGuru> I thought you can use script.fex on linux :-P (ignore my ramblings... n00b here)
<ssvb> vector80: don't know about android, but currently in linux u-boot sources need to be modified to change dram parameters
<vector80> Clear, so here is my second question
<vector80> The only file for dram parameters is seemed to be dram_blabla.c
<ssvb> yes
<vector80> And in that file, most safe one seems that dram clk and CAS latency
<vector80> Are there anything else to tune there?
<ssvb> well, it depends, not everything is "safe"
<vector80> I read your emails about it,
<vector80> and it seems 432Mhz seems to be safe
<vector80> However cubieboard use 480Mhz ?
<vector80> I mean, by using mbw, how I can make sure one setting is safe ? Change parameters, and try for hours ?
<vector80> My board is an A20, it has 2x512Mbyte DDR3 Hynix H5TQ4G63AFA
Lumocolor has joined #linux-sunxi
<ssvb> use https://github.com/maxnet/a10-meminfo to check if the u-boot changes have taken effect
<ssvb> and run https://github.com/ssvb/lima-memtester/ for hours to see if it fails or not
<vector80> Clear
<vector80> Let me do it.
<ssvb> is this cubieboard2 or some other hardware?
<vector80> No, it is Interra-3
<vector80> I try to write my best on the sunxi wiki,
<ssvb> does it already have support in u-boot?
<vector80> Yes, for the 1st time, oliver made the commit, and I modified it a little,
<vector80> now it works almost perfectly
<vector80> For the 1st time, oliver used mele's dram parameters, that time I run a10-meminfo on my board for him
<vector80> and he selected that parameters
<vector80> however, later I started learning about this beaitiful community, very helpful people here
<vector80> So I compiled my own uboot and my own kernel
<vector80> Now everything seems working fine,
<vector80> but I feel some slow reactions
<vector80> so I wondered if it is related to Dram setting or not
<vector80> In my current uboot, without modifications, here is my mbw result: http://pastie.org/9150875
<vector80> yes, that is oliver's commit
<vector80> I changed that one now
<vector80> Changed the name of the file, and changed clock to 432
<vector80> And result is above
<vector80> but I still feel it is slow
<vector80> so I would like to start testing by changing Clk and CAS
<vector80> cloning lima-tester
<vector80> compiled succesfully
<vector80> let me try it
<vector80> waww
<vector80> it is amazing
<vector80> testing on two board at the same time
<vector80> one of them is connected to a 10.1" Samsung LCD via LVDS
<vector80> resolution is 1280x800
<vector80> There is a rotating cube with a heart on it :)
<vector80> The cube has some artifacts on it
Guest91984 has quit [Remote host closed the connection]
<vector80> during rotation, I can see some mosaics
w00tc0d3 has joined #linux-sunxi
w00tc0d3 is now known as Guest42825
<ssvb> that's just tearing effects, the animation framerate is much higher than the monitor refresh
<ssvb> in the case of troubles, the background is going to start glowing red or just the whole device deadlocks
<vector80> clear
<vector80> And I also saw a few pixels near to top right side was blinking during sequential increment test
<vector80> Now it disappeared
<vector80> I am testing with 256Mbyte,
<vector80> it that a correct value for testing ?
<ssvb> that's fine, the size of the tested memory block does not matter much
<vector80> Alright, two boards have started at the same time
<vector80> So, what I could do it
<vector80> do is
<vector80> I can change parameters on one board
<vector80> and start lima-memtester
<vector80> wait until morning
<vector80> see what happens
<vector80> right ?
bbrezillon has joined #linux-sunxi
<ssvb> you can try to increase the dram clock speed until it fails very fast, then step back a bit and run lima-memtester until morning
<vector80> Alright, which value I must start with ?
<vector80> Such as 500Mhz ?
<ssvb> you can try something around 480MHz
<vector80> Ok, let me do it now
<vector80> Change CAS latency ?
<ssvb> don't touch it yet, the cas=9 settings are good up to 667MHz, so you can first try to find the highest clock frequency
<vector80> Clear, I am compiling for 480 now
pseudomind has joined #linux-sunxi
<vector80> completed, loading to my eMMC
<vector80> both boards have updated with 480Mhz uboot's, and starting lima-memtester
avsm has joined #linux-sunxi
<ssvb> have you verified the actual dram clock frequency with a10-meminfo?
<vector80> oh my god
<vector80> I forget it
<ssvb> just to be sure that your manipulations with u-boot really have some effect ;)
<vector80> Let me do it
fredy has quit [Excess Flood]
<vector80> ssvb, it looks changes has taken effect: http://pastie.org/9150956
<vector80> Right ?
<ssvb> yes, looks good
<vector80> so, let me try with lima now
fredy has joined #linux-sunxi
<vector80> waw waw waw
<ssvb> ?
<vector80> I find something very important difference
<vector80> I have two boards
tomboy64 has quit [Remote host closed the connection]
<vector80> in one of them, I connected to LVDS LCD
<vector80> so its resolution is 1280x800
<vector80> however the other one is set to HDMI output
<vector80> with 1920x1080
<vector80> So, I am testing on two boards, with different resolution
<vector80> Is that a correct testing way ?
<ssvb> it should not matter much
<vector80> because 1920x1080 is significantly slower than 1280x800
<vector80> tests are completed very after other one
<vector80> ssvb, have a look at this photo, I almost started both test at the same time: http://imgur.com/10Ft1BZ

<ssvb> yes, 1920x1080 runs slower, but it should not affect the overall test result (pass or fail)
<ssvb> if lima-memtester can run more than a few minutes without failing and you are bored, then you can move to 504MHz
<vector80> yes, they are still running

<vector80> the cube still rotating, I can still access to my board via SSH..
<vector80> Let me try 504Mhz now

<vector80> ssvb, CPU gets extremely hot during the tests, I don't have a thermometer in my home now, but I feel it is more than 65degree celcius, is that normal ?
<vector80> A20 doesn't have a internal controller for extreme heat, am I wrong ?
<ssvb> vector80: there is a temperature sensor in a20 and also another one in the axp209 power chip (which also should be hot)
<vector80> ssvb, you are no:1, thank you very much for this info.
<ssvb> try to run the 'sensors' tool and you may already see the axp209 temperature
<vector80> let me try
<vector80> ssvb, here is my problem: http://pastie.org/9151012
<vector80> something wrong in my kernel ?
<ssvb> hmm, what is your kernel version?
<vector80> 3.4.79
<ssvb> too old :)
<vector80> I highly modified mine
<vector80> yes, I know you are mainlining ?
<vector80> Which kernel I should try ?
<vector80> sunxi-next ?
<ssvb> I think the axp209 sensor support was added only in sunxi 3.4.86
<ssvb> no, just a more up to date sunxi-3.4
<vector80> Alright,
<vector80> let me try to clone again
Lumocolor has joined #linux-sunxi
<ssvb> btw, how many patches do you have applied? are they doing something useful that could be shared with the others?
<torindel> out of boredom: any page with merge status of linux-sunxi kernel with vanilla one?
leviathanch2 has joined #linux-sunxi
<vector80> ssvb, I sent emails to sunxi mailing list regarding my modifications
<vector80> some of them were only for my hardware, such as adding MUTE pin for audio
leviathanch2 has quit [Remote host closed the connection]
<vector80> some of them were common, such as fixing non-working i2c-3
<torindel> ssvb: thx
<vector80> Turl helped me a lot, oliver helped me a lot
<vector80> many other friends here are very helpful, thank you soo much
<vector80> I am just cloning linux-sunxi, is that 3.4.86 now ?
<ssvb> vector80: yes, that should be it
<vector80> Ok, let me try it

<vector80> ssvb, in the top level makefile, it still write 3.4.79, did I clone wrong tree: git clone https://github.com/linux-sunxi/linux-sunxi.git
<vector80> ??
leviathanch2 has quit [Ping timeout: 240 seconds]
<ssvb> vector80: hmm, you are right
<vector80> So, which branch I should clone ?
<Turl> stage/ is .86
<vector80> Turl, wellcome back :)
<Turl> hey vector80 :)
<vector80> how are you tonight ?
<vector80> oh my god sorry
<vector80> you are still in daylight, right ?
<vector80> it is 23:21 here
<ssvb> vector80: which is one of the recent additions here - https://github.com/linux-sunxi/linux-sunxi/commits/sunxi-3.4
<vector80> Clear
<vector80> Let me clone it
<vector80> thank you very much
<ssvb> vector80: well, you have already cloned it
<Turl> vector80: yeah it's 17:22 :)
<Turl> you don't need to clone again, just use git to change branch
<ssvb> vector80: just your previous 3.4.79 kernel did not seem to have the HWMON patch
<vector80> Ok
<vector80> Let me change branch
<vector80> copy my .config
<vector80> and try to recompile
<vector80> lets see what happens
<ssvb> vector80: maybe it's the case of "sunxi-v3.4.79-r0" vs. "sunxi-v3.4.79-r1" tags
<ssvb> vector80: oh, or maybe HWMON is just disabled in your .config
<vector80> waw
<vector80> let me check
<vector80> is it CONFIG_HWMON or something like it?
<vector80> oh my god
<vector80> in my config,

<ssvb> vector80: https://github.com/linux-sunxi/linux-sunxi/commit/fcec507519157765 says that it is in sunxi-v3.4.86-r0 and sunxi-v3.4.79-r1
<ssvb> vector80: maybe you have sunxi-v3.4.79-r0?
<vector80> yes, but I don't know how to change my HEAD to 3.4.86
<vector80> Can you explain how to do that?
<vector80> I cloned linux-sunxi already, but I don't know which command needed to change to that specific commit
tm512_ has joined #linux-sunxi
<ssvb> vector80: it should be already in your cloned working copy
<vector80> yes, so I must use one command to change to latest commit, otherwise, in my copy, it still writes 3.4.79
<vector80> But I don't know how to do that
<ssvb> vector80: 3.4.79 (-r1) is ok, it was my mistake assuming that you need 3.4.86
tm512 has quit [Quit: Just relax and enjoy this pleasant adventure]
<vector80> how to understand if it is r0 or r1 ?
pseudomind has quit [Quit: pseudomind]
<ssvb> vector80: just run 'git log' and check if you see the AXP_HWMON patch there
<vector80> let me see
<vector80> yes, I see it
<ssvb> then it should be good
<vector80> Ok let me compile it
<vector80> but
<vector80> but but
<vector80> I can't see AXP_HWMON in make menuconfig
<vector80> is that normal ?
<ssvb> have you tried searching for it?
leviathanch2 has quit [Ping timeout: 252 seconds]
<vector80> How to search while I am in menuconfig ?
<ssvb> like pressing '/' and entering AXP_HWMON in menuconfig
<vector80> waw
<vector80> let me do it
<vector80> Oh my god
<vector80> you are totally right
bonbons has quit [Quit: Leaving]
<vector80> So, since I disabled hardware monitoring support in mainmenu
<vector80> even those AXP209 thing were already enabled in my kernel
<vector80> sensors didn't find anything
<vector80> Ok, I enabled it
<vector80> and compiling again
<vector80> Does a20 also have a HWMON ?
<ssvb> yes, but it is shared with the touch panel controller, which makes it a bit tricky

<vector80> You mean, I should edit some part of the kernel ?
<vector80> BTW, both boards are still running lima, and they are about the end of 2nd loop
<vector80> Should I change clock to higher value, or change CAS ?
<vector80> Last values were 504Mhz and CAS=9
<ssvb> vector80: about the A20 temp sensor - http://www.cubieforums.com/index.php?topic=2293.0
<vector80> let me read
<ssvb> vector80: that's a long thread which explains the whole story, but the patch itself can be taken here - https://github.com/ssvb/linux-sunxi/commit/3cc6d008057be0074c44f6a0efa13c0eab6ab243
<vector80> ok let me get it
rz2k has joined #linux-sunxi
<vector80> waw, it need to disable TP ? Sorry but I use my FT5x TP, I can't live without it
<ssvb> vector80: yes, "it is shared with the touch panel controller" has some implications
<vector80> clear
<vector80> So, lets currently forget about it
<vector80> temporarily
<vector80> Do you recommend higher frequency for my DRAMs ?
<ssvb> well, you can try 528MHz
<vector80> ok CAS will be still at 9, right ?
<ssvb> yes
<vector80> ok
<vector80> So, every step, should be multiple of 24Mhz ?
<ssvb> yes, unless you are using a very recent u-boot
<vector80> very recent uboot?
<ccaione> mripard: so, what I do with the syscon patches?
<vector80> Is there a very recent uboot for a20 ?
<vector80> let me see it
<ccaione> vector80: you are flooding my log. Please keep your thoughts on a single line without splitting every three words :)
leviathanch2 has joined #linux-sunxi
<vector80> ccaione, sorry for that
<ccaione> no offense ;)
<vector80> :)
<Turl> FT5x is capacitive over the i2c bus isn't it? you don't need to disable it
<vector80> yes right
<vector80> so it has nothing to do with TP controller inside the A20
<vector80> I am flooding again, very sorry
<ccaione> hahahaha it's ok
<vector80> :)
<Turl> ccaione is just being picky :p
<vector80> BTW, did you get latest complete 4.4 kitkat for A31 ? Does it worth for you ?
<ccaione> :D I'm being a finger in the ass
<Turl> that reminds me I need to review oliv3r's chapter, melita is gonna kill me otherwise

<ccaione> lol
<ccaione> my shirt for the next job interview
<Turl> :P
<ccaione> hahahaha
<vector80> Turl, I couldn't understand one point. FT5x driver in current kernel is loaded as a module, it doesn't compile as builtin. But even as a module, it still need some symbols from sun4i-ts, otherwise it crashes... Do I make a mistake in module loading ?
<Turl> vector80: hm, I haven't looked at it, maybe the code is just crappy and it really does depend on it
<vector80> I feel so
<vector80> ssvb, I have bad news.
<vector80> The board without LCD screen, at 504Mhz, it stopped working
<vector80> I just rebooted it manually
<vector80> So, it seems 504Mhz is a high value :(
<ssvb> vector80: step back to 480mhz and run the test until morning :)
<vector80> clear
<ssvb> vector80: the other board may be more overclockable, the overclocking limit may vary between different chips
<vector80> well, tomorrow morning I am starting to program 1100 pcs for one big customer, I will try to use 432Mhz one just to make sure :)
<vector80> Let me try 480Mhz until morning, see what happens.
<vector80> After that I will sleep
<vector80> I will finally ask two questions to you, not anymore
<vector80> I already took a lot of your time, thank you soo much for it
<ssvb> vector80: as for 504MHz being the high value, there is still some hope for faster dram speeds and we are currently investigating http://linux-sunxi.org/DDR_Calibration
<vector80> 1) Why you never recommended to change CAS latency? is there a reason for that?
<ssvb> vector80: CAS latency is independent from clock speed and it is better to test one thing at a time
<ssvb> vector80: moreover, there are other timing parameters, not just CAS latency alone
<vector80> I see
<vector80> I wish to continue on trying this
<vector80> So I will read DDR_calibartion
<vector80> 2) Is there a work for enabling hardware encoder on A20 to be able to capture camera and encode to h264 ?
<ccaione> vector80: so are you making money on allwinner?

<vector80> ccaione, currently yes, I love these chips. I know there are much better ones, but these are enough powerful for my work, and price is quite acceptable
<vector80> And the good point is you people,
<ccaione> :D
<vector80> I never see such an active mailing list and IRC
Nyuutwo has joined #linux-sunxi
<vector80> there are a lot of smart and experienced people over there

<vector80> Would you recommend IMX ? TI ? Exynos ?
<vector80> Ok, see you
leviathanch2 has quit [Ping timeout: 240 seconds]
<Turl> vector80: the main advantage of big names like Freescale and TI is that they assure you product will be available long in the future
<Turl> and most of the times they have detailed docs as well
