<sky770> Is there anyone who is updated on reverse engineering the Allwinner a10's VPU ?
<sky770> any updates regarding the project?
<orly_owl> mali 400? or is that the gpu?
<sky770> inside the A10 allwinner SoC we got the Mali400M the GPU; inside the whole package we got the CedarX VPU
<sky770> am talking abt the CedarX VPU :D
<sky770> a deal breaker :/ IMO
<rz2k> we just dont have enough people capable of reversing vpu stuff.
<rz2k> and people interest in allwinner seem to fade.
<sky770> true
<sky770> All were* hanging on allwinner until it became a reality..
<sky770> well, Amlogic certainly has good prospects in this area :D
<rz2k> only if they would support opensource and help, afaik people still dont have u-boot sources or something basic like that
<rz2k> also they have gpl-violating NDA, but thats another story.
<sky770> I am clinging onto Tom cubie :D
<orly_owl> are there any satellite/terrestrial stb using allwinner soc?
<orly_owl> *is there

<Gumboot> Anyone got any juicy A6 gossip?
<Gumboot> That question may force me into full disclosure mode.
<hno> A6?
<lundman> Ihave A4,lots of them
<Gumboot> Apple A6. I hadn't anticipated that they'd skip the Cortex A15, but it sounds like they have.
<Gumboot> But I don't know if that's confirmed.
<hno> Is A6 relevant to open?
<Gumboot> Not directly, but it's a point of reference.
tzafrir_laptop has joined #arm-netbook
<VarmVaffel> If the datasheet for my ARM mcu says that the EMI starts at 0x40000000, wouldn't that be the most logical starting point for the DRAM?
<hno> Gumboot, From the little I know it's not a Cortex neither in design or instruction set.
<Gumboot> I'm pretty sure the instruction set will be consistent with Cortex.
<Gumboot> ARM would probably freak out, otherwise.
<Gumboot> (that being entirely my own opinion, and all that shit)
<Gumboot> Cortex A series, I mean.
<Gumboot> I don't know if the Cortex branding will continue to non-ARMv7 IP.
<Gumboot> Hm. Looks like the big delay at the start of building Android is a shell script... ?
<hno> Gumboot, it's a custom ARMv7 based instruction set, dubbed armv7s by Apple, implememented in a custom core design.
<akaizen> sky770: rz2k: I'm interested in the CedarX and MALI400. Working on re-doing the interface to libve and implementing the VBV and FBM into a proper driver/module
<Gumboot> Crikey.
<Gumboot> That's going to cause some distress.
<rm> $53 capacitive A13
<Gumboot> hno: Got a reference?
von_fritz has joined #arm-netbook
<akaizen> I saw empat_zero got it working, so maybe the VBV, FBM and adapter from the sdk will work. But some specific init_data for the decoder for specific codecs is missing from the documentation
<Gumboot> I guess it's one more thing that works out just like Intel. The eventual arms race of ill-conceived instruction set extensions. It'll be just like AMD versus Intel and IE versus Netscape.
* Gumboot finds a reference but suspects it might be bullshit.
* akaizen off to sleep
<hno> Gumboot, only whata anandtech reported
rellla has quit [Remote host closed the connection]
<hno> and have no reason to distrust. Apple certainly have both resources and the right people to pull that off.
<hno> and speculations immediately started on Apple switching to ARM for Macbook in future.. guess that's still pretty far off the map however.
<Gumboot> It seems unlikely that they'd implement non-ARM-sanctioned extensions.
<Gumboot> What I'm seeing suggests that it's just A15-class instructions, though. Not their own extensions.
<Gumboot> Oh. Good. xcode is dropping ARMv6 support.
<techn> mnemoc: Dunno if that patch is needed for r2p4 libraries.. but anyway I got gles acceleration working(with es2gears and glmark2-es) with r2p4, but ie xbmc crashes.
<techn> but I'm currently trying to make that patch work with r3p0/1
MrWHO has joined #arm-netbook
<MrWHO> I was wondering if there was anyone in the channel... it seems really busy! :)
<hno> MrWHO, yes it's a quite active channel.
<MrWHO> I have an image for my MiniX - Mele_HTPC_120907_V1.2.img - and I'm on linux. I tried to use the depacker from https://github.com/amery/sunxi-tools/blob/master/phoenix_info.c, and it complains that it's not a Phoenix image. Funnily enough it ships with the PhoenixCard application...
<MrWHO> ..is it possible that the format of the image has changed? There is no "PHOENIX_CARD_IMG" in the image... so it would seem of a different kind of family
hp__ has quit [Read error: Connection reset by peer]
* cat1 : allwinner added cpufreq_governor with rather funny name "fantasy" :D
<hno> MrWHO, that tool is for dissecting SD images written by phoenixcard.
<hno> The actual firmware image format is encrypted & obfuscated, and to my best knowledge there is only Windows tools for unpacking them.
<MrWHO> I see...
<hno> the ones who know the format do not want to talk about it.
<hno> but there is two known tools developed outside Allwinner that can unpack the image format.
<hno> plus that Allwinner also have a tool somewhere.
<hno> in addition to Livesuit and Phoenixcard which both obviously also know how to unpack the firmware image.
<MrWHO> Do you know where I can find the tools?

<popolon> what is this computer ? I believe the link was wrong on the page I found it
<popolon> (by clicking on the Soc scheme on this page)
<penguin42> oh wacky
<penguin42> popolon: I'd assume that's an ARM versatile express development board loaded with a few processor modules
<penguin42> popolon: Click ont he click for larger image on there
<popolon> ok, thanks penguin42
<popolon> :)
madmalkav has joined #arm-netbook
<penguin42> popolon: The versatile express is basically a motherboard that you then choose a CPU module for, it's what ARM seem to release there new cores on first as their internal test board
<popolon> is ARM the manufacturer of versatile express ?
<penguin42> popolon: I think so
<popolon> oh, thanks
<penguin42> popolon: the board is built so you can build test boards for whatever hardware you're going to build into a SoC

<mnemoc> techn: so x11/gl working? :)
<rz2k> mnemoc: still no luck for obvious same libs/x11dr2i/drivers setup
<rz2k> somehow you can make r2p4 work with r3p0 drivers but I didnt get how to do that, I have kernel oopsing with that
<rz2k> with r3p0/1 any gl app dies with 12288 or 12296
<mnemoc> ouch
<rz2k> most weird stuff is that 12288 is egl_success error
<mnemoc> who oopses? disp or mali?
<mnemoc> or drm? or ump?
<rz2k> ump
<techn> rz2k: I managed to get gles acceleration with r2p4 user and kernelspace
<rz2k> what patch did you apply for r2p4? there is not buf1/2 there
<rz2k> only get_secure_id
<rz2k> s/not/no/
<techn> get_secure_id ioctl is same as buf1 ioctl
<techn> but not sure if that patch is even needed with r2p4.. only difference is that memory lenght is halfed
RITRedbeard_ has joined #arm-netbook
<rz2k> I cant reproduce it unfortunately :( I'm only getting http://pastebin.com/Bjig0K7C with r2p4 kernelside, r2p4 libs and your patch
<techn> rz2k: you'll need to chmod /dev/ump

<rm> f*ck
<rm> this one does not have pins

<hno> rm, uart?
Gujs has joined #arm-netbook
<rm> yes
<rm> or... hm
<rm> ^ ...what?
<mnemoc> not nice
<rm> "Ok, spoke with the factory and the 4 pins are not UART. There is a flymouse that is an optional add-on. The receiver for the fly mouse uses these pins for the connection."
<Yaku> thx, just didn´t know exactly where to look, i just opened the mobile ap option and it opened the accesspoint and could connect to my mele from my sgs+, but i do not seem to be able to get to the internet, the box got a connection while under status it says it doesn´t i still can access the web from the box itself
<Yaku> really seems to be the right channel since ur also working with an a10 device rm :)
RITRedbeard_ has quit [Ping timeout: 246 seconds]
<hno> rm, so it's USB then.
<hno> most likely.
<rm> Yaku, people discuss the A10 devices here 90% of the time
<rm> so it is indeed the most suitable channel in all of freenode for your question
<hno> and not so much the EOMA68 A10.
<rm> naturally, people tend to discuss things which exist
<Yaku> was thinking of buying an ug802
<Yaku> but that´s rk3066 and no sources :/
<hno> do the mele firmware have tethering support?
<Yaku> yes
<Yaku> i could put a 3g stick in there and it would thether
<Yaku> tether
<Yaku> but i want to share the ethernet rather then the 3g connection to have a mobile ap in a hotel
<hno> that's more of an Android question than A10.
<Yaku> what´s the best channel for android network related subjects ?
<rm> I guess there has to be #android
<hno> if not someone there should know.
<Yaku> guess i have to register in irc to get rights for the channel
<CIA-15> rhombus-tech: master * r2992d4f136d0 /allwinner_a10/orders/olex.mdwn:
<hno> Yaku, being registered with nickserv is always a good idea.
