<ssvb> what would be the best place to find the latest boot0 sources for a10?
HeHoPMaJIeH has joined #linux-sunxi
physis has joined #linux-sunxi
<oliv3r> wens: we should add the a23 BROM dump to the allwinner-info repo, which hno maintains
<oliv3r> ssvb: 'latest'? I don't think we have any for a10. we do have them for a20 though if i'm not mistaken
<wens> oliv3r: I haven't sent a pull request yet
<oliv3r> you extracted it?
<wens> yup
<oliv3r> it's deff. good to have at the least
<oliv3r> i think documenting the a10 one, that we have now will be enough
<oliv3r> i think simple comparissions showing that it's about the same will be sufficient
<oliv3r> of course anybody that cares about its securty etc will have to do the work for whatever BROM they require, or if someone gets bored :)
<ssvb> oliv3r: I just wonder about the origin of all the ifdefs in the sunxi u-boot dram init code
physis has quit [Ping timeout: 252 seconds]
<oliv3r> ssvb: the ifdef sun4i else sun5i?
<oliv3r> or what specifically?
<oliv3r> (anybody happen to have the link to the rhumbus tech git handy?
<oliv3r> oh i think i have it in my email
<ssvb> oliv3r: yes, somebody must have unified the sun4i, sun5i and sun7i parts
<oliv3r> we did
<oliv3r> tom cubie (tjang lang or something, hipboi) worked on the a10 code
<oliv3r> which he got from boot0 code
<wens> might add A23 boot0 (from the SDK) to that
<wens> no boot1 found (doubt there is one)
<oliv3r> yeah but boot1 is very much not important
<oliv3r> wens: yeah i noticed that from the logs, it seems they dropped boot1 in favor of u0b-boot
<ssvb> oliv3r: do we still have some original allwinner dram init code for a10?
<oliv3r> i have it unofficially
starchild has joined #linux-sunxi
<oliv3r> if you have a way for me to send you 70 mb
<wens> oliv3r: i tried looking at boot0, but nothing like dram init stuck out :(
<oliv3r> wens: in which sdk?
<wens> oliv3r: A23
<oliv3r> ah yeah,; but it should be really identically to a31 stuff
<oliv3r> which you found on rhombus-tech (if you can relink me pls :)
<ssvb> oliv3r: hmm, 70mb is too much, just this one, but for a10 would be enough - https://github.com/hno/allwinner-boot/blob/lichee-a20-dev/boot0/drv/init_dram/dram_init.c
<wens> also we have 2 versions of a31 dram init code, 1 from rhombus-tech u-boot, 1 from A23 SDK linux standby code
<wens> oliv3r: http://git.rhombus-tech.net/?p=u-boot.git;a=blob;f=arch/arm/cpu/armv7/sunxi/dram_sun6i.c;h=9275ca21ac99592c7d520a41c0914b359c27b913;hb=refs/heads/lichee/jb-4.2.2-a31

<oliv3r> ah! i had that git repo open :p cool cool
<ssvb> oliv3r: I would like to see how it looked with "modify for A20" change reverted :)
<oliv3r> not that branch :)
<oliv3r> ssvb: should be in the history; let me find you the commit
<ssvb> oliv3r: oh, sorry, it indeed does have git history
<oliv3r> t back then
<oliv3r> luke copy/pasted the stuff from the A20 sdk that he had back then
<ssvb> so it was not just a tarball drop, that's excellent
<oliv3r> erm it was
<oliv3r> the a20 sdk was

<nabblet> hi, i wrote a guide for crosscompiling and installing gentoo for olinuxino a20. THIS IS STILL WORK IN PROGRESS and following the guide will not give you a working install! http://paste.debian.net/93213/ I am pasting this for feedback!
<plaes> nabblet: why don't you add ti to wiki?
<plaes> s/ti/it
<nabblet> plaes: because it is not ready yet. Also this is more of a personal scrachpad right now. as soon as my process is reliable and resulting in a working setup i will publish accordingly
<nabblet> plaes: also my guide might be more suitable for olimex and gentoo-embedded... so right now i am not fokusing on any wiki-style or wiki-requirements
<nabblet> plaes: that said i'm eager to contribute to your wiki if things are working :)
<nabblet> also because i got lots of help here :)
<nabblet> but now i want to know: is it understandable, is it clear to follow, and maybe where i am missing an important step
<nabblet> (i get kernel panic because of missing init - i have not investigated yet)
<nabblet> plaes: you should copy my paste, save it as html and look at it in a webbrowser

<rm> A20 is a pretty good CPU
<rm> you'll be hard-pressed to find something genuinely better
<y0g1> rm it is to slow for mysql database + bind + minidlna + mldonkey +.... setup
<rm> as in: same feature set, same level of support in open-source code, and similar price
<y0g1> rm: I know, but there are better cpu models, similar to A20
<rm> are you sure it's the CPU, and not your storage?
<y0g1> rm I would like to see knew cubietruck board model with one of them
<rm> what's your OS installed on?
<y0g1> y0g1: I use sata 2TB drive
<rm> okay
<y0g1> rm: armedslack with kernel from linux-sunxi
<specing> y0g1: buy an intel
<bfree> did you set the governor to performance or something saner then 60MHz?
<y0g1> Timing cached reads: 798 MB in 2.00 seconds = 399.10 MB/sec
<y0g1> Timing buffered disk reads: 366 MB in 3.01 seconds = 121.59 MB/sec
<y0g1> bfree: I use performance governor
<y0g1> bfree: I like low power of CT, it is not more than 20W. When I used intel Pentium 4 then my server used over 80W
<y0g1> bfree: but to have perfect home server it is a bit slow,

<bfree> well comparing to a P4 is silly, something like the Intel J1800/J1900 would be fairer
<rm> but it does not have SATA
<y0g1> rm thanks, I will check it
<starchild> cluster maybe?
<y0g1> rm I have to do few routers that will redirect udp traffic and count it with embeding into my monitoring system. I will try it there
techn_ has joined #linux-sunxi
<y0g1> starchild: to complicated. CT is very handy, small and universal board. I need to make it very solid for use in production systems
<y0g1> rm I need sata for ma home server only for testing, but for my customers CF or internal NAND is enough

<hramrach> bfree: why is comparing to P4 silly? the netburst architecture sucked so much that it might actually approach the performance levels of an A10 ;-)
<hramrach> actually, the A10 has memory performance of about half an odroid which has memory performance of about an Atom CPU which uses the old Pentium chipset so ..
<bfree> hramrach: produced 2000-2008 so at best 6 years old, old space-heaters at this point ;)
<hramrach> and an A10 gives comparable performance without the heat
<starchild> hramrach: what is A20 comparable to?
<hramrach> an A10
<starchild> no diff?
<hramrach> there it no impressive performance improvement
<hramrach> the performance is different but not even obviously better
physis has joined #linux-sunxi
<rm> afaik it's somewhat slower on single-threaded workloads
<hramrach> depends on the workload
<hramrach> if memory bound it depends on your memory tuning
<hramrach> and there a20 has more options but is not obviously faster either
<hramrach> and given the used core a10 has fester neon (usually only of use for hand-craftes decoder routines) but on a20 you can mix neon and non-neon arithmetic with little penalty which is more comppiler friendly
<hramrach> and so on
physis has quit [Ping timeout: 252 seconds]
<specing> If the A10 ran at 3.6Ghz it would probably suck as much as the pentium4, despite it being 6 years newer tech
<hramrach> the core design for A10 or any arm for that matter sucks. That's why in spite of Samsung having almost as good manufacturing process as Intel they cannot produce a CPU anywhere nearly as powerful as Intel

<Renard> Hello everyone! I bought a A20-based device with no prior knowledge that libstagefright/xbmc wouldn't work properly with it. Read a bit about the issue and well, here I am. Thanks for trying to tackle the issue.
<oliv3r> Renard: so what exactly is your question?
<Renard> So far, none. I'm reading the wiki to learn more about that chip.
<oliv3r> so what issue is in need of thanks on trying to tackle?
<Renard> Work on integrating CedarX support, in order to get proper 720p/1080p playback

<oliv3r> Renard: ah ok i thought you had a generic question :)
<Renard> Well, the generic question would be along the lines of "how the heck do I make this thing work?", but it seems the wiki already has quite a lot of stuff covered
<Renard> including a how-to build XBMC for A10
<rm> you mean like http://linux-sunxi.org/XBMC
<Renard> Exactly
<Renard> I've also read that the existing Cubieboard images would work on my device
<Renard> (I should probably add that device to the wiki)
<oliv3r> but as far as I know xbmc with the open source stuff isn't happening just yet
<Renard> How come that Mali GPUs don't play well with stagefright ?
<oliv3r> you are asking questions about Blobs, to the opensource guys ...
<oliv3r> you should ask arm that question, they wrote that stuff :)
<Renard> mind you, I don't know anything about stagefright
<Renard> I thought the goal of that project was also to include binary blobs
<Renard> "DRM framework" - oh.
<Renard> and yes, I'd love to ask the guys at ARM :)
<Renard> "VidOn.Me Player - Seems to be a fork from empatzero" hm, what
Fusing has quit [Ping timeout: 252 seconds]
<oliv3r> Renard: basically, with only opensource stuff; there's no xbmc just yet
<oliv3r> with blobs, you've come to the wrong place to ask, as it doesn't really work well yet
<ssvb> Renard: if you just want to watch videos, maybe Android would be a reasonably good choice for you?
<Renard> Thanks for the link
<oliv3r> ok how the hell did I just do this, my screen is somehow 'zoomed' and moving the mouse moves the desktop slightly too
<oliv3r> i recall edge scrolling with bigger virtual resolutions in like 1998
<Renard> Android: nah, not decent as a media center. Also NFS seems to be quite a pain in the Android kernel.
<oliv3r> ah, new xfwm zoom feature, alt + wheel
<Renard> compiz?
<Renard> is xfwm composited?
<starchild> Renard: I have the same use case. except I want to add a dvb-s card to the mix.
<Renard> Neat. I used to run tvheadend to get some dvb-t streams on my lan, with xbmc as one of the clients. Worked great at the time :)
<oliv3r> Renard: yeah it is; but it's quite a new feature, so it caught me off guard
<oliv3r> i have dvb-t and dvb-s(2) on my server
<oliv3r> the ultimate plan is to have xbmc on an a10/a20 device; but we're not there just yet
kuldeepdhaka_ has quit [Ping timeout: 276 seconds]
<Renard> It seems that the A10 and A20 are quite close, would A10 binaries work on an A20 as-is?
<Renard> (ie. compiling the XBMCA10 branch on an A20)
<Renard> (or using pre-compiled images)
<oliv3r> should work more or less
