05:01.06sky770hi all ^_^
05:01.40alcideshi
05:02.06sky770hey alcides, ssup
05:31.27sky770Is there anyone who is updated on reverse engineering the Allwinner a10's VPU ?
05:31.37sky770any updates regarding the project?
05:37.35orly_owlmali 400? or is that the gpu?
05:38.34sky770inside the A10 allwinner SoC we got the Mali400M the GPU; inside the whole package we got the CedarX VPU
05:40.04sky770am talking abt the CedarX VPU :D
05:40.24sky770a deal breaker :/ IMO
05:45.17rz2ksky770: https://github.com/empatzero/xbmca10
05:46.16rz2kwe just dont have enough people capable of reversing vpu stuff.
05:46.27rz2kand people interest in allwinner seem to fade.
05:53.23sky770true
05:53.44sky770All were* hanging on allwinner until it became a reality..
05:54.16sky770well, Amlogic certainly has good prospects in this area :D
05:55.23rz2konly if they would support opensource and help, afaik people still dont have u-boot sources or something basic like that
05:55.43rz2kalso they have gpl-violating NDA, but thats another story.
05:55.57sky770I am clinging onto Tom cubie :D
05:59.37orly_owlare there any satellite/terrestrial stb using allwinner soc?
05:59.42orly_owl*is there

09:52.37GumbootAnyone got any juicy A6 gossip?
09:53.01GumbootThat question may force me into full disclosure mode.
09:54.35hnoA6?
09:55.49lundmanIhave A4,lots of them
09:56.49GumbootApple A6.  I hadn't anticipated that they'd skip the Cortex A15, but it sounds like they have.
09:56.54GumbootBut I don't know if that's confirmed.
09:57.57hnoIs A6 relevant to open?
09:58.19GumbootNot directly, but it's a point of reference.

10:00.05VarmVaffelIf 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?
10:00.52hnoGumboot, From the little I know it's not a Cortex neither in design or instruction set.
10:01.21GumbootI'm pretty sure the instruction set will be consistent with Cortex.
10:01.31GumbootARM would probably freak out, otherwise.
10:01.51Gumboot(that being entirely my own opinion, and all that shit)
10:04.17GumbootCortex A series, I mean.
10:04.48GumbootI don't know if the Cortex branding will continue to non-ARMv7 IP.
10:08.22GumbootHm.  Looks like the big delay at the start of building Android is a shell script... ?
10:10.36hnoGumboot, it's a custom ARMv7 based instruction set, dubbed armv7s by Apple, implememented in a custom core design.
10:10.53akaizensky770: 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
10:11.05GumbootCrikey.
10:11.17GumbootThat's going to cause some distress.

10:11.27Gumboothno: Got a reference?
10:12.38*** join/#arm-netbook von_fritz (~fritz@host21-184-dynamic.54-82-r.retail.telecomitalia.it)
10:13.31akaizenI 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
10:15.25GumbootI 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.
10:17.45Gumbootfinds a reference but suspects it might be bullshit.
10:27.57akaizenoff to sleep
10:28.11hnoGumboot, only whata anandtech reported
10:29.19hnoand have no reason to distrust. Apple certainly have both resources and the right people to pull that off.
10:31.05hnoand speculations immediately started on Apple switching to ARM for Macbook in future.. guess that's still pretty far off the map however.
10:32.18GumbootIt seems unlikely that they'd implement non-ARM-sanctioned extensions.
10:33.09GumbootWhat I'm seeing suggests that it's just A15-class instructions, though.  Not their own extensions.
10:33.58GumbootOh.  Good.  xcode is dropping ARMv6 support.
10:35.41technmnemoc: 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.
10:36.17technbut I'm currently trying to make that patch work with r3p0/1

10:37.03MrWHOI was wondering if there was anyone in the channel... it seems really busy! :)
10:40.28hnoMrWHO, yes it's a quite active channel.
10:42.45MrWHOI 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...
10:43.37MrWHO..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
10:47.55cat1: allwinner added cpufreq_governor with rather funny name "fantasy" :D
10:51.49hnoMrWHO, that tool is for dissecting SD images written by phoenixcard.
10:52.48hnoThe actual firmware image format is encrypted & obfuscated, and to my best knowledge there is only Windows tools for unpacking them.
10:52.50MrWHOI see...
10:53.26hnothe ones who know the format do not want to talk about it.
10:54.39hnobut there is two known tools developed outside Allwinner that can unpack the image format.
10:54.51hnoplus that Allwinner also have a tool somewhere.
10:55.23hnoin addition to Livesuit and Phoenixcard which both obviously also know how to unpack the firmware image.
10:57.20MrWHODo you know where I can find the tools?
10:59.49technhttps://github.com/techn/linux-allwinner/commit/e7e2feb36a66f19cb53e31e27e101fc66456be82 , if anyone wants to test
11:00.03hnohttp://forum.xda-developers.com/showthread.php?p=25978796 has one.

13:13.52popolonis ARM the manufacturer of versatile express ?
13:14.32penguin42popolon: I think so
13:15.06popolonoh, thanks
13:15.58penguin42popolon: the board is built so you can build test boards for whatever hardware you're going to build into a SoC

19:16.12Yakureally seems to be the right channel since ur also working with an a10 device rm :)
19:16.29hnorm, so it's USB then.
19:16.47hnomost likely.
19:18.45rmYaku, people discuss the A10 devices here 90% of the time
19:19.07rmso it is indeed the most suitable channel in all of freenode for your question
19:19.09hnoand not so much the EOMA68 A10.
19:19.24rmnaturally, people tend to discuss things which exist
19:19.29Yakuwas thinking of buying an ug802
19:19.48Yakubut that´s rk3066 and no sources :/
19:20.06hnodo the mele firmware have tethering support?
19:20.11Yakuyes
19:20.30Yakui could put a 3g stick in there and it would thether
19:20.34Yakutether
19:21.10Yakubut i want to share the ethernet rather then the 3g connection to have a mobile ap in a hotel
19:21.33hnothat's more of an Android question than A10.
19:22.17Yakuwhat´s the best channel for android network related subjects ?
19:23.04rmI guess there has to be #android
19:24.35hnoif not someone there should know.
19:25.13Yakuguess i have to register in irc to get rights for the channel

21:14.40rmsomehow I am a bit fed up with these A10 devices
21:15.00rmunlike x86, when it fails to boot you can't see any debug output
21:15.19rmand those ass clowns put USB pins instead of UART
21:15.23rmbecause yay fly mouse
21:15.37*** join/#arm-netbook tuliom (~tuliom@186.214.50.30)
21:18.41rmalso the U-host has only one USB host port externally
21:18.56*** join/#arm-netbook eflatun_ (~eflatun@46.1.238.108)
21:18.57rmand it seems to have a hard time powering a passive hub + 3-4 devices on it

21:23.27merbzt4*0.5A = 2A
21:24.08merbztso you need quite a beefy power supply for that use case
21:24.28*** join/#arm-netbook mysteryname (~mysteryna@14-202-9-167.tpgi.com.au)
21:25.32specingmerbzt: usb keys and keyboard usually don't drain 0.5A :)
21:27.56merbzttrue, but if it is a small device with one usb port then it usually only have power enough for that also'
21:31.47technrm: put disp modules inside kernel, then you'll see whats the problem
21:32.11technunless problem is earlier than disp is inited
21:32.31technbut atleast userspace problem are easily debugable now
21:34.30technmnemoc: yes.. manual seems to have g2d registers described
