<libv> to aid identification, i have created http://linux-sunxi.org/Format_Q8
<libv> i intend to do the same for 2 other 7" formats, the one with the 3 real buttons on the front and the one with the 3 capacitive buttons on the front
<libv> not sure what i should name those formats yet though

<libv> because those two other formats were only sold in 2011-2012
<libv> i am going to call one A7
<libv> as most of the boards seem to start with that

<nove> libv: but still wouldn't be good to contact them to make aware of us, they what to sell tablets, and our wiki could be a place to put details of what they are selling
<nove> no?
<plaes> I think that they won't probably bother to do that.. :S
<nove> plaes: did you seethe videos, they are really trying to reach non-china, with bad english but still trying
<plaes> the video where one guy basically walks the whole assembly line?
leviathanch has joined #linux-sunxi
<nove> yes and others
<hramrach> hello
<hramrach> what videos?
<hramrach> might be nice to see how Chinese pretend to make tablets
<nove> as example they give table model ZXS-A23 9 inch, but searching for that gives no results
<hramrach> fun
<hramrach> did you win a tablet?
<hramrach> also fun
<nove> no, as i am not a social websites user, i can't click the button
<hramrach> I can hear my screen scroll
<hramrach> EMI ftw
<specing> lol

* plaes wonders how they added the gsm functionality..
<hramrach> did you notice how the openspace office is almost empty?
<plaes> which video?

<plaes> 5 tablet giveaway?
<hramrach> yes, if you click two buttons
<plaes> haha.. yes
leviathanch has joined #linux-sunxi
<hramrach> also note how the thing you pin photos to has very few photos pinned
<hramrach> waste of space .. in China, yeah right
<plaes> ~40s ?
<plaes> at 55seconds
<hramrach> yeah, there
<plaes> "..., no problem!" :)
<hramrach> the fans ..

<hramrach> do you think that even Chinese have work condition regulations so they have to put the fans there to blow away the fumes or they are to speed up cooling of the joints?
<specing> I think the workforce is expendable there...
leviathanch has quit [Ping timeout: 240 seconds]
leviathanch has joined #linux-sunxi
<hramrach> well, every cheap tablet they sell abroad brings a little more money to China. Eventually even the billions of Chinese will get rich enough to refuse to be treated as expendable ..
rta has quit [Ping timeout: 246 seconds]
<specing> What is the average pay of a factory worker in china?
<specing> s/pay/wage/
<hramrach> I have no idea but it must be very low if it's cheaper to do the stuff manually than building an automated production line
<hramrach> some stuff is hard to automate but tablet assembly is not exactly in the hard to automate category

<hramrach> is this not Q8? http://linux-sunxi.org/GONOMAD_PWS700YA
<hramrach> and this looks like Q8+ - extra long PCB
<hramrach> and does the format used by Inet 86vs/vz/Polaroid PMID906 have some known name?

<Seppoz> one question
<Seppoz> how can i make a boards.cfg parameter in uboot to a preprocessor variable, like ifdef MYVAR
<Seppoz> where arm armv7 cubieboard allwinner sunxi sun4i:SPL,NO_AXP,MYVAR
<libv> hramrach: nope
<Seppoz> nevermind figured it out
<libv> hramrach: completelt different side
<Seppoz> missed the CONFIG_
<libv> hramrach: those are also completely different.
<libv> hramrach: check the pictures.
<libv> now the gonomad is one of the 2 other formats.
<libv> hramrach: how they can be confused is beyond me
<libv> Q8 is pretty easy to spot.
<libv> i even have very clear connector/button pictures.

<hramrach> ok, gonomad has camera in the corner, probably
<hramrach> and SD slot mounted on the other side of the PCB. Not all that different
<hramrach> but can't tell the difference between Inet 86vs/vz/Polaroid PMID906

<lauri> Hey guys
<lauri> Trying tpr3 trick as I speak :)
<lauri> dcdc3 voltage was already 1.3V in default FEX
<lauri> Interestingly a10-meminfo-static still shows 0 for tpr3
leviathanch has joined #linux-sunxi
<lauri> ssvb: ^^
<lauri> so it's a bug in the meminfo utility, okay let's assume the setting is correct then :P
<lauri> what should I expect from this change? More stability? It's clocked at 480MHz currenttly
leviathanch has quit [Ping timeout: 240 seconds]
leviathanch has joined #linux-sunxi
<ssvb> lauri: with better tpr3 settings, dram can be clocked roughly 100MHz higher while retaining the same level of stability
<lauri> alrighty
<lauri> so what frequencies I could try? 528MHz? 552MHz?
<ssvb> it's up to you, actually we need more data about the stability
<lauri> alrighty
<lauri> I'll report ;)
FreezingCold has joined #linux-sunxi
leviathanch has quit [Ping timeout: 240 seconds]
<ssvb> lauri: you can try both 528MHz and 552MHz, and run lima-memtester with these settings for many hours (an overnight run for 8-10 hours should be a good test)
<ssvb> lauri: and then please report if any problems were detected
<lauri> sure :)
<lauri> so this would mean rougly 20% more memory I/O speed right?
<ssvb> there are also some other factors, like more correct timings for the selected clock frequency
<lauri> a10-meminfo reports 528MHz :)
<lauri> feelsgoodman.jpg :)
<ssvb> lauri: what about the hdmi signal disruption problem? have you seen these glitches with the increased dram clock speed?
<lauri> not yet
<lauri> offtopic: it feels good finally to sit at a workstation that is NOT x86 :D
<lauri> offtopic: I missed the SPARC and PowerPC era :P
<ssvb> btw, I got a lot of test data with dram timings and trp3 setup, will post the results soonish :)
<ssvb> and implemented some useful tool in the process - https://github.com/ssvb/a10-meminfo/commits/master

<lauri> not so offtopic: the point being that my ITX box has been turned off for more than a week by now. Cubietruck satisfies 99% my needs.
<lauri> Currently only Skype is missing..
<lauri> I wonder how slow would be statically linked skype with QEMU emulation?
<starchild> why not webrtc
<lauri> starchild: Implying that I am the problem...
<lauri> starchild: It's the other users who are the problem
<starchild> it just needs a modern browser
<lauri> I'd rather use Jabber, but now even Google scrapped it's support in Google Hangouts :/
<starchild> the use case is video chat or just text?
<Turl> lauri: you could use android for skype

<byECHO> linux linaro-nano 3.4.61
<Turl> byECHO: can you run make linux-config on the bsp and make sure DRM_MALI is enabled?
<byECHO> It's not enabled. I never run linux-config before. Anyway I will build it again see if it works.
<byECHO> Thanks
<ssvb> 3.4.61 is a bit old
<Turl> ssvb: bsp needs a submodules update

<lauri> ssvb: Okay I watched a 1h30min 720p clip
<ssvb> lauri: is it good or bad? what's that supposed to mean?
<lauri> ssvb: I had one HDMI link disruption and one lockup (some kernelspace thingie locks up everything for about 10secs)
<lauri> ssvb: generally same experience as 432MHz without tpr3 hack
<ssvb> so you are generally observing approximately 1 problem in 1.5 hour on average, right?
<lauri> something like that
<lauri> I also noticed some video playback jitter, like occasionally dropping some frames
<lauri> usable but not 100% perfect :)
<ssvb> then we need a better way to reproduce this problem, it does not look particularly severe in your case :)
<ssvb> and the 10sec lockup is strange
<lauri> I am (still) not sure whether the HDMI link disruption is caused by fridge etc.
<lauri> But the lockup thing is really sdtrange
<lauri> I am guessing it has something to do with SATA
<lauri> In dmesg I have failed command: READ FPDMA QUEUED
<lauri> interface fatal error etc

<lauri> I am pretty sure the SSD is okay, I used in in my laptop for while
<lauri> Perhaps something to do with powersave?
