<mnemoc> everyone to .kr :)
<techn_> crazy ppl.. work from 8-20
<Mehhh> Yeh, we can work on the Galaxy S IIIIIIV Replay Nexus 4G
<techn_> japanize^2 :p
* mnemoc prefers a place where people can work 12h/d than a place where people feels abused if they can't pass 2h/d in a bar
<techn_> :D
<rz2k> their 8-20 work is demanded by europe/usa, when things will fall apart (europe dying in economics fustercluck, etc.), they will suffer even more then we will.
<rz2k> very simple example is allwinnertech, if european ODM/OEMs will stop reselling/rebranding products due to investors being extremely careful - allwinner will lose tons of money and most likely will not pay the manufacturing debts, thus will lead to allwinner going down or something like that. :p
<mnemoc> allwinner doesn't rely in EU/US sales
<rz2k> manufacturers of the products that go to europe rely
<rz2k> when they will see zero demand..
<rz2k> count of segments in this chain doesnt matter
<techn_> also allwinner is chinese firm.. south korean firm are completely different
<mnemoc> .kr relies in EU/US far more
<techn_> south korea is like a child for US :p
<techn_> what .. they gave chevrolet for them :p
<mnemoc> lima lima lima!

<rz2k> yeah, libv pushed 20+ commits to lima repo @ gitorious
<mnemoc> and he is very good at quake :p
<rz2k> thats the standard demo
<mnemoc> oh :(
<rz2k> interesting, exynos4412 kernel has different mali driver
<rz2k> different in everyway
<rz2k> it is called vithar
<techn_> rz2k: money talks :p
<rz2k> has a binding to ION memory manager
<rz2k> ump is there, but different too
<rz2k> also wired to ion
<rz2k> mali libs seem to be somewhat same, but have a mix up of stuff I've seen in our libs + mali200 functions + new maligp2 stuff.
<rz2k> and as I said, their commercial(?) bsp has our mali_drm 1:1 line, lol.
<mnemoc> rz2k: isn't "our" mali_drm just the open source mali_drm from arm?
<techn_> mnemoc: It's slightly modified
<rz2k> no, it was fixed for new drm + it has two devices
<rz2k> for two framebuffers
<techn_> I think we took that from lima :/
<rz2k> from igloocommunity
<rz2k> but they had it broken too
<hno> Wonder what ARM tested the release on.
<rz2k> their drm module?
<hno> No, the mali ddk release.
<techn_> hno: most likely it's just proof on concept.. and they will sell their services to buyer
<rz2k> no idea, seems like the SoC manufacturer should do many stuff on its own
<rz2k> having Mali DDK
<hno> Yes, but still some group in ARM is writing that DDK and I have to assume they actually test it on something.
<rz2k> atleast mali drm seems to be tested on 2.6.x and full list of SoCs is in file around
<rz2k> only thing that I recongnize is tcc8900
<techn_> u8500 is st ericsons chip
<rz2k> xserver driver is written for s3c2xx
<rz2k> according to ioctls
<rz2k> might be that they have reference designs
<rz2k> done by different SoC manufacturers like telechips, samsung, st-ericsson...
lerc has joined #arm-netbook
<penguin42> rz2k: I think there are lots of things like this on ARM where two vendors, each deciding they couldn't possibly tell anyone else what they were planning to do, end up writing the same code
lerc_ has quit [Ping timeout: 276 seconds]
<rz2k> they've merged t6xx and mali-400 in one driver
<rz2k> for android
<rz2k> anyway its 4AM and its time to go to bed.
<rz2k> good night.

<Turl> mnemoc: you call "never >30C" hot weather? :P
<mnemoc> Turl: no, I live in the "cold" part of spain
<mnemoc> and I love this weather ;-)
<mnemoc> I call >45C hot weather
<penguin42> I think about 23c is my just-right point
<techn_> +25 is hot weather :)
<mnemoc> :)
<mnemoc> 18-23c is a nice range
<Turl> 15- even
<mnemoc> depends the humidity
<Turl> and even less if you need to expand the range :P
<Turl> the humidity is not a problem with cold weather
<Turl> heat on the other side..
<Mehhh> Has anyone tried running 1.2ghz @ 1.4V ?

<Turl> Mehhh: I've played with clocks, yeah
<Turl> 1.2 works with the stock values usually
<Mehhh> stock @ 1.2 is 1.5V on the Mk802
<Mehhh> 1056-1200
<Turl> couldn't get much more than that, even bumping voltages
<hno> +/-30C is nice range.
<Mehhh> 912-1008 = 1.4 i think?
<hno> excluding +/-3C
freakazoid0223 has quit [Quit: Leaving]
<Turl> hno: +/-30C relative to what?
<hno> 0
<Turl> 30C is too hot
<Turl> -30C probably requires special care
<techn_> only one month to -30C weathers :p
<orly_owl> will be 37C here today
<Turl> 20C now :D
<techn_> -20C now :)
<Turl> ouch
<hno> you don't wear shorts in -30C.. Proper clothing is required or you'll surely risk get permanently hurt from freeze damage.
ccssnet has quit [Read error: Connection reset by peer]
<hno> Only -8 here now.
<hno> and lots of snow in the last days.
<Turl> it doesn't snow over here
<Turl> :(
<penguin42> Turl: Feel free to send us a few of those C in this direction
<penguin42> at least it's +ve tonight
<Turl> penguin42: sure, I can ship you 10-15C
<penguin42> great!
<Turl> if you can wait I can prolly get you ~30-35C early next year

<techn_> hno: about that my boot problem.. it's propably not clock problem.. could it be interrupt problem? should we consume all interrupts @ u-boot.. before enabling them? or something like that?
<techn_> .. it could also be clock problem.. but not sure yet
<techn_> It could be that opening gate which is already open freezes device :/
stefanro has joined #arm-netbook
stefanro1 has quit [Ping timeout: 276 seconds]
<hno> techn_, opening an open gate have no effect.
<hno> techn_, and if interrupts needs to be consumed before enabled then the driver is broken.
<hno> u-boot do not enable any interrupts.

<libv> i like a20 already
<hno> libv, even if /arch/arm/mach-sun6i/built-in.o is all the sources there is?
<libv> and i pushed 84 commits out to the lima repo
<libv> mnemoc: no input is wired up to that quake, so i couldn't show off my real quake sk1llz
<libv> oh, i would think that at some point something should fall out of allwinner that we can use
<Maqs> libv: it's better that way. otherwise it'd be like formula one.. always the same guys winning.. :P
<libv> i like the a20, i do not like the a30
<libv> for reasons which are absolutely not mali related ;p
<libv> Maqs: from what i picked up left and right, formula 1 was relatively interesting this year
<libv> and it was quite an exciting last race apparently
<Maqs> ok, let's say boxing.. :-)
<libv> pin compatible with a10 is also grand
<libv> now we just need the crap .cn code
<libv> and the actual hw
<hno> libv, the A13 code fell out of Allwinner only because of a git mistake from someone in marketing, combined with one manufacturer not following SDK release procedure and accidently included the git repository in their release.
<Mehhh> lol
<libv> hno: would they have caught up on the fact that this actually helped them?
<libv> A serial processor
<libv> how quaintly chinese.
<hno> Probably they do not at all realise that A13 OlinuXino would not exist if that had not happened, despite repeated complaints.
<hno> libv, yes they need someone with slightly better english writing skills helping with their web site..
<hno> libv, when asked why sun5i arch sources are all binay their only respones is "you should not touch that" or "there is no need for you to touch that".
<libv> *sigh*
<hno> they also made u-boot nand driver binary-only but I think that's to cover up something.

<jinzo> huh, A31 uses SGX
<jinzo> and A20 is dual core - looks like it's time that I finish the comparison table
<mnemoc> and 2x mali too
<mnemoc> rm: that's probably a mistranslation. A serie processors (cortex-a7), F serie processors (arm9)
<mnemoc> jinzo: they added a mini table to http://www.allwinnertech.com/en/product/A-Serial.html
<jinzo> mnemoc, allright - I plan to add more information (interfaces mostly)
<mnemoc> +1
tinti has joined #arm-netbook
Quarx has joined #arm-netbook
<jinzo> mnemoc, http://linux-sunxi.org/A10s -> some sample stuff that I need to improve ofcourse
<jinzo> I'm thinking of breaking up memory (tech | max size),USB (OTH|Host), Storage and adding links to the pages
<jinzo> but I would like to run it by you if that's roughly what you expect
<jinzo> and then there's A12 as it looks like
<jinzo> I'll first try to set up this table in some roughly good way - then I'll hit on creating wiki pages for new processors
<hno> jinzo, A12 == A10s from all what I can understand.
<jinzo> how's the Datasheet avability for A20, A12, A31?
<jinzo> ah, interesting
<jinzo> A31 looks neat - I suppose no boards available yet?
<jinzo> too bad it's SGX
rz2k has joined #arm-netbook
<jinzo> and A13 has Android 4.2 - that looks neat too - I'm waay to out of this stuff as it looks like :D
<jinzo> you don't hang here for a week and everything changes
penguin42 has joined #arm-netbook
<mnemoc> hno: it's pretty confusing they list both A12 and A10s at http://www.allwinnertech.com/en/product/A-Serial.html
<mnemoc> jinzo: it doesn't make much sense to me to add the comparison table within the page of one of the SoCs
<mnemoc> jinzo: also, it might work better in the other direction. SoCs as columns instead of rows
<mnemoc> the a20 is likely to be sun6i because it's multi-core
<mnemoc> but no way to know until there is code
niftylettuce has quit [Remote host closed the connection]
<jinzo> mnemoc, yes I know - but I needed a place to experiment and I did it there
<jinzo> I'm planing to move it out and just provide a link/something

vgrade_ has quit [Ping timeout: 245 seconds]
<hno> mnemoc, yes. very confusing. Maybe both exists after all? Wonder where they differ.. (same package, same specifications as published so far, different market segments)
<mnemoc> hno: i suppose they have a different feature set
<mnemoc> a10s without lcd and a13 without vga for example
<mnemoc> a12
<mnemoc> maybe the 8 uarts of the a10 for the sake of supporting more radio chips
<mnemoc> it's really sad how they behave regarding sources and documentation considering how awesome their chips are :|
<jinzo> and how much they could gain (being the underdogs compared to other bigger chip makers)
<mnemoc> someone suggested they need to hide the info to avoid been sued by patent lawyers
<jinzo> yeah - that was brought up in the FSF-Endorsable processor thread too.
<slapin> hi, all!
<jinzo> but on the other hand Intel and PowerVR showed that they can release open source drivers (albeit shitty ones) with poulsbo
* slapin got another batch of mk802 clones, these ones have original layout (no axp209), ad IGB of RAM
<jinzo> price?
<mnemoc> slapin: same dram params?
<slapin> mnemoc: yeah
<slapin> jinzo: where is powervr open source drivers?
<slapin> mnemoc: same board as with early 512MB version
<slapin> but memory chips are different
<jinzo> slapin, the Intel's integrated graphic cards were in fact PowerVR's (they bought them) http://software.intel.com/en-us/articles/poulsbo-chipset and https://wiki.archlinux.org/index.php/Poulsbo
niftylettuce has joined #arm-netbook
<jinzo> this driver has been quite famed in the linux world, because of Intel's failure to produce a good driver
<jinzo> some more info: http://www.phoronix.com/scan.php?page=news_item&px=MTEyMjU (even it it's phoronix)
<rm> not all intel graphics is from powervr
<rm> I'd say only a minority of models
<jinzo> yes - but it's quite an example how a big company like Intel had big problems with the open drivers for the chip
<libv> jinzo: intel did not own the gpu
<libv> jinzo: imagination does
<libv> jinzo: and even then, a company like amd does not own all of the IP in the radeon hw they stupidly bought with ati
<jinzo> yeah I know - but they have quite some sway and I'm baffled how they couldn't produce a good driver

<Maqs> a simple a10 board without any (unnecessary) connectors should be quite light..
<hno> jinzo, the intel open source graphics & GPU driver is not for pulsbo, only pretty much every other intel embedded graphics.
fkardame has quit [Ping timeout: 245 seconds]
<hno> the only open source drivers for pulsbo is the reverse engineered driver by Alan Cox, made completely wihtout any documentation and lots of guesswork.
<hno> Intel can not help with that. They are bound by NDA contracts to not say a word about the hardware detals, most likely not even register names.
