<markusr> I am looking at the A20-OLinuXino-MICRO. Is it possible to put also uboot on sata?
<libv> markusr: nope
<libv> well, not without being able to completely rewrite brom
bertrik has joined #linux-sunxi
<wens> markusr: the on-die bootrom only checks mmc, nand and spi
<Net147> are all the EDID settings read from HDMI besides pixel clock actually used to configure the HDMI output signal? e.g. horizontal and vertical blanking and other timing parameters
<markusr> so practically you need a small microsd card.

<robincook> hi, its a simple question, that, I don't remember how to recompile boot1 on my sun7i. what is the command in ./lichee/boot/boot1 ? thank you.
libcg has joined #linux-sunxi
<libv> mripard: perhaps, but i still think that this is a clear sign that we are not better than other SoC projects, and that we have no real reason to stick with clueless gpl violating allwinner
<libv> we are development board centric, just like everyone else, let's go board hopping, just like everyone else

ricardocrudo has joined #linux-sunxi
<libv> not at this time, no
<arokux> libv: could you make your code public maybe?
<libv> i have stated this before.
<arokux> libv: oh, sorry, I haven't noticed it.
<oliv3r> libv: boardhopping? what happened?
<libv> arokux: no, not until it is featureful enough to not further dumb down the chances for more than just development board support
<libv> oliv3r: most people in the arm space are either working for a vendor more or less directly, or are constantly hopping boards and SoCs
alexst has joined #linux-sunxi
<oliv3r> i see
<libv> it's not helping, as they at best are papering over some issues before they jump to the next platform

alexst has quit [Ping timeout: 256 seconds]
<oliv3r> libv: not a prob
<oliv3r> libv: means i got some refreshing to do :)
<mripard> libv: but what could have happened is that it happened too early
<Gerwin_J> end of this month you can buy A80 optimus board
<libv> mripard: what happened to early? the creation of the fex to dt translator?
<libv> too even
<Gerwin_J> Will not sell by Allwinner but by chinese partner
<mripard> I mean, people that should be interested in babelfish are the one that have a tablet that is not supported at the moment, at all. which implies tablets/STBs. Would you put a headless system on such a device with limited inputs/connectivity?
<Gerwin_J> price will be around 325 dollar
<arokux> Gerwin_J: o_O
<libv> mripard: is babelfish even documented on our wiki? i have not bothered to look, as i have not gone near mainline
<libv> it is not even mentioned
<libv> mripard: it's time to write a guide on how to get $device ported to mainline, and to feature babelfish in it
<libv> also mention it in topics related to fex

<rds> libv: status of the KMS driver, please? ( just kidding )
<rds> A80 board for $325 + shipping
<rds> I wonder who is crazy to buy it. I bet it will be a big flop
<rds> For that price you can buy a finished product
<rds> not a dev board without any functional SW on it.
<rds> better they come back to reality and price it at ~ $69
<Dodger78> got problems with cubietruck on gigabit network speeds
<Dodger78> standard clock, tried to raise voltage , no success, tried to change from ring DMA to chained DMA ,no success, things got worse.
<Dodger78> got a 3.4.98 latest kernel from 3.4 series
rz2k has joined #linux-sunxi
<Dodger78> what i recognize by using iperf, only one transfer direction fails . the other one is better
<Dodger78> afaik TX is crashing
<Turl> Dodger78: have you tried the latest fex from sunxi-boards with fixed dcdc voltages?
<Dodger78> if you ask me , stmmac / gmac kernel driver has serious problems
<Dodger78> im using cpufreqd and the cubieez 1.0 fex
<Dodger78> shall i give that a shot ? my volt supply is 1.45V which is cubieez 1.0 std
alexst has joined #linux-sunxi
<Turl> you can try setting performance governor as well
<Dodger78> ok one sec
<Dodger78> this will set volt to max then right ? ( and clock )
<Turl> yes, and it should not change frequencies depending on workload
<Turl> Dodger78: also see https://github.com/linux-sunxi/sunxi-boards/commit/2d3330814b38a2a857958b3b3fd97c3f473bfd7b and make sure the fex you're using is up to date with these changes
<Dodger78> ok , set performance doesnt help ( alone ) i do compare fex now
<mripard> rds: dev boards are usually much more expensive
<mripard> at least by an order of magnitude
<rds> rpi changed the landscape of these boards
<mripard> no
<Dodger78> Turl, im even a little above these values
<mripard> rpi is not a development kit.
<mripard> it's a toy
<Turl> Dodger78: on dcdc2_vol and dcdc3_vol?
<Turl> what values do you have there?
<rds> well, what is the CB3 ?
<rds> or any AW's based dev board ?
<Dodger78> 1450, 1300 on dcdc
<Dodger78> the dvfs is a bit higher for some mv
<mripard> rds: allwinner's development kits are around 2000$
<Turl> Dodger78: hm, ok
<rds> well, let's wait and see. Time will tell.
<Turl> Dodger78: dunno then, you may want to wait for ssvb_
<Dodger78> 1460 for 912mhz, and even 1485 for 1ghz
<Dodger78> ok thx for the tip
<ssvb_> Dodger78: try to grep your dmesg log for "buck"
<ssvb_> Dodger78: it should reveal real dcdc2 and dcdc3 voltages
<ssvb_> Dodger78: the 1485 value makes no sense, because the smallest step is 25 (so it would be 1475 or 1500)
<Dodger78> hi ssvb , i grep it a sec
<Dodger78> i got some "bucks" what happens then ?
<Turl> Dodger78: paste them on pastebin or somewhere
<oliv3r> ssvb_: have you seen my msg?
<oliv3r> mnemoc: do you think you can find out (via hipboi maybe?) why allwinner is ignoring us?
<oliv3r> i even asked eva via my work account, but nothing
<kivutar> I'm trying to get hdmi sound on my cubieboard2, I have hdmi.audio=EDID:0 in my cmdline, I have sound working on jack, I have CONFIG_SND_SUNXI_SOC_HDMIAUDIO=y in my kernel config
<kivutar> what can it be?
<mnemoc> oliv3r: tom is ignored as well. he is in the queue to get the reference design info for A80. benn is closer to AW, but benn ignores us too
<oliv3r> great
<oliv3r> amazing
<oliv3r> would it be an Idea to get through to AW via linaro?
<oliv3r> not that linaro seems to care much
<mnemoc> oliv3r: saw the latest libv's post? :p
<oliv3r> yeah
<oliv3r> that's why iw as wondering
<oliv3r> i know they use it as a 'shield'
<oliv3r> libv: btw, I think you got anand's name wrong, i think it needs el or al inbetween
<ssvb_> Dodger78: the voltages look good
<ssvb_> Dodger78: maybe check your power supply and/or the power cable?
<oliv3r> libv: or was it lal? i don't recall
<oliv3r> mnemoc: what about tsvetan?
<mnemoc> in his post he pasted the specs from aw's product page
<mnemoc> so I bet he also doesn't have anything yet

<oliv3r> well i'm mostly interested in contact/avenue for communication

<oliv3r> it always either pulls in crap
<mnemoc> oliv3r: it's the "Senior Manager for Global Business Development"... and a western... who might understand better the problem if explained correctly
<mnemoc> at least there is not language barrier
<oliv3r> go go go!
<mnemoc> mripard is directly connected to him. i'm not
<Turl> oliv3r: :/
<mripard> oliv3r: no, I only have contact with engineers
<mnemoc> mripard: and that guy from linkedin?
<Turl> mnemoc: that guy is on all expo videos with the armdevices vlogger
<oliv3r> mripard: which won't help in getting any gpl violations resolved :)
<mripard> oliv3r: why?
<oliv3r> well we still need some sources resolved
<oliv3r> cedarX technically, boot0 for a23
<mnemoc> libnand, etc...
<oliv3r> i contacted eva wu, but have received zero reply
<oliv3r> and i contacted her via work, since we are an opensource company and our stuff is opensource too
<mnemoc> libv also sent her a detailed list of violations in the A23 SDK
<mripard> mnemoc: do I really have to justify every relation I might have on linkedin?
<mnemoc> mripard: of course not, I only mean you _can_ contact him
<mripard> mnemoc: I had a phone call with him once, more than a year ago
<mripard> oliv3r: lkcl isn't dealing with this anymore?
<mnemoc> eva also added me, and she never ever replied one of my mails when we started this quest...
<mripard> he's the one who sent me the A31 EVK
<oliv3r> mripard: i think he kinda gave up
<mnemoc> mripard: maybe him could be a better contact to solve the GPL violations...
<mnemoc> he*
<oliv3r> mripard: i'd love to argue with eva etc, but it's hard to argue when you get ignored :(

<mnemoc> the cedarx library is shamelessly based in ffmpeg, that should be a good weapon, if they care at all
<mripard> Turl: yeah, but we have the source for that, don't we?
<oliv3r> well it does give you some 'weight'
<Turl> mripard: not of libnand, libisp, etc

<Dodger78> hope the a80 cubieboard has less problems ^^ :-(
<CaptHindsight> has it been confirmed that the new A80 cubieboard is SATA Free?
<Dodger78> at least is got usb3 , so who cares ?
<Dodger78> you can attach hd there
<oliv3r> i wonder how well their usb3 implementation will work
<oliv3r> depends on the IP they bought really
<CaptHindsight> and how they connected the IP
<oliv3r> well usb3 ip seems to be riddled with bugs and issues
<jemk> the a80 source from cubietech contains a new libschw blob ...
<CaptHindsight> USB has lousy real time performance since the latency can be so long
<Turl> jemk: what's that?
rds has quit [Ping timeout: 246 seconds]
<CaptHindsight> so USB dongles are great if you don't care about doing anything real time
<jemk> Turl: looks like something security/drm/crypto related https://github.com/cubie8/linux-3.4/tree/linux-dev/modules/aw_schw
<oliv3r> Turl: one big advantage is using the owncloud-sqlite && owncloud mysql-server- method, no mysql configuration pops by, so while it is nasty technically, it does work :)

<oliv3r> Turl: the getid3 has to be installed seperatly via the -t parameter though; it won't install the proper version as per dependancy
<oliv3r> CaptHindsight: how much do you know about usb latency?
<oliv3r> CaptHindsight: we are seeing some usb latency issues (on usb2) too and blame usb, but we haven't investigated it yet
<CaptHindsight> oliv3r: do you need a copy of the spec?
<oliv3r> we are concidering using a bigger buffer on the receiving end
<oliv3r> CaptHindsight: no, user experience is far more valueable :)
<CaptHindsight> it's just bad since the spec didn't care about low latency
<oliv3r> well for us its semi realtime
<oliv3r> it's a lot of small round trip packages
<Turl> oliv3r: yes, you always need -t when installing backports stuff
<oliv3r> well yeah
<oliv3r> but if something from the backports has a depenancy, version wise, it won't pull that from backports
<Turl> jemk: looks ugly, that much I can say :p
<CaptHindsight> oliv3r: on the cubie2 we are using SPI and some GPIO lines for real time 1-2Mb/s to a FPGA
<bonbons> Turl, Dodger78: for CubieTruck ethernet, I seem to be seeing the TX issues as well, on 3.4.x kernel as wells as 3.16-rc
<oliv3r> yeah we are going to use SPI anyway
<oliv3r> we are short on ports anyhow :p
<oliv3r> (usb ports)

<bonbons> though it looks more like it's a packet the driver/hardware does not like as usually it kills the corresponding tcp connection
<CaptHindsight> preempt_rt latency jitter is ~80uS, xenomai ~40uS
<arokux2> ijc: hey, what about acking the driver itself? :)
<bonbons> previous and later packets of the connection get through, with SACK hint for the missing packet(s) but usually it does not recover
<CaptHindsight> anyone get a banana pi yet?
<bonbons> I didn't look at whatever tcp-offloading options there are that might break/unbreak things - running on defaults
<CaptHindsight> http://www.bananapi.org/ saw one on aliexpress for 2x the price
<ijc> arokux2: I'm hoping to do a push to u-boot-sunxi.git#master either today or tomorrow which will include the gpio thing the patch depends on.
<ijc> I aso wanted to give marex a chance to comment

<ijc> ssvb_: I was talking about the denx.de custodian tree not the github one
<nove> oliv3r, mnemoc, we should not make statements without having profs (they can make them scared, and ignore us), and were is the prof of cedarx libraries having anything to do with ffmpeg, i never saw anything concrete to back this
<ssvb_> ijc: yes, I'm talking about the denx.de custodian tree
<nove> not that i or jemk look at it, alias we avoided to look inside the binaries, so that we didn't get dirty
<ssvb_> ijc: so it would be very nice if you could wait at least until tomorrow
<Skaag> is there a way to safely dd the SD image of a remote unit over to me?
<ijc> ssvb_: I probably won't get to it before then anyway. and there's always another PR
<Skaag> ok with netcat

<oliv3r> nove: there is prove, we found stuff, i think we had it on the wiki at some point
<oliv3r> nove: me and wingrime investigated all this in the early days :)
<nove> oliv3r: similar symbols names and the sames coefficient tables of the codec standard, i think doesn't count
<ssvb_> ijc: thanks
<oliv3r> nove: we had harder proof then that :)
<oliv3r> nove: i don't wish to taint you
<oliv3r> nove: but i can tell you this much
alexst has quit [Ping timeout: 240 seconds]
<oliv3r> for every codec supported, they simply took the reference sample code they found online and put it in cedarX (with parts in the hardware bit of course)
<oliv3r> nove: hence, jpeg support in cedarX is really the libjpeg source code in linux, and that's fine, because it is not GPL licensed, all you need to do is supply the jpeg readme or something (they didn't even bother with that)
<oliv3r> nove: and for some bits, they blalantly used ffmpeg source code
<oliv3r> but it's now hidden somewhere in the wiki history
<oliv3r> as i can't find them in the active pages
<oliv3r> nove: but i'm not hugly worried about cedarX, as it is RE'ed a lot allready
<nove> oliv3r: prof is need, dissembled parts of the binaries, that matches without doubt gpl licensed source code
<nove> oliv3r: without that ids only void statement that we are making (that will not help us)
<oliv3r> nove: we had that :)
<oliv3r> they also never denied it

<nove> if (i very much doubt) sources were released, nothing would change, other than more noise would be made, with allwinner being labeled as a savior in the news
<nove> we would be in the same situation
<nove> only needs to looks at the kernel sources, to see that would be very unlikely that we would get the real important part
<nove> that is hardware documentation

<nove> so, same thing, but now with the added "why is still not ready if allwinner released the sources? that sunxi folks can't do anything"
<nove> the hard part is no do reverse engineering (that is the fun part)
<nove> that real hard part is to write the driver (in the right way)
<nove> specialty with this unshaped kernel media frameworks
<nove> and is only us two (i and jemk)
<nove> two people that before this adventure didn't have any experience in video codecs and without kernel driver development experience

<mripard> like... the soc family?
issue_ has quit [Remote host closed the connection]
<popolon> oh, yes, I think to add like the sunxi family
<popolon> some start with sun7i sun6i, etc..
<popolon> that's at least an easy method to find it
<popolon> i fist, following the tuto, searching at cubie*

<mripard> well, yes. some start with sun7i because they're devices based on sun7i, some other on sun6i because they're based on sun6i
tomboy65 has joined #linux-sunxi
<libv> popolon: you do know that sun used to be the maker of solaris/sunos and sparc machines, right?
<popolon> So sun* is the easiest way to find it
<popolon> yes
<libv> sun?i is where it is add.
<libv> not sun
<popolon> nice
<libv> s/add/at/
<popolon> you can suggest it like that yes
<libv> heh, it's been 4 years already
<popolon> As far I know, sun doesn't make arm devices anyway
* Turl scratches head
<popolon> and the begining of the name of the dtb/dts is the name of the Soc, not of the company
<mripard> popolon: then why don't you just say so in the wiki
<popolon> that's in arch/arm/boot/dts/
<mripard> instead of saying "hey, it starts with sun"
<popolon> that was just to help user to find the file an easier way
<mripard> why don't you say "it ends with dtb too"
<mripard> "oh, and it's a file"
<popolon> ???
<popolon> that's already said

<popolon> do you have another way to help better the user to find the file concerning it's own card ?

<mripard> be careful what you wish for ;)
bgal has quit [Ping timeout: 260 seconds]
<mripard> popolon: it should start with the family of the SoC?

<Turl> mripard: patches welcome :)
<mripard> "sunxi" family?
<mripard> what do you mean?
<Turl> mripard: can you suggest an audio player for buildroot?
<mripard> it's the family name used by allwinner
<mripard> what more do you want?
<mripard> Turl: ogg123, aplay?
<Turl> I'd like something more flexible than mpg123
<mripard> mplayer ? :)
<mripard> mpd?
<Turl> mpd is a daemon :p
<mripard> yet it plays music
<mripard> so it qualifies
<Turl> mripard: I want something to test 24/16bit audio
<Turl> mpg123 served me well for mono/stereo so far :)
<mripard> I think speaker-test does
<popolon> well, if reader try to find sunxi, it will not found sun?i*
<Turl> speaker-test only does 16/32
<mripard> erf
<popolon> that's a wiki if you have better idea, you can change it
<Turl> and the noise is making me deaf by the day :p
<mripard> popolon: except sunxi is not a family...
<popolon> oh, the families are sun5i, sun6i, sun7i...
<mripard> popolon: yes, of course, but if I could not spend time undoing changes other made, that would be great.
<mripard> that being said, good night, I'm off to bed
<Turl> " it should start by the word "sunNi", where N is a number, followed by your device name"
<Turl> just write something like that and keep everyone happy :p
<mripard> Turl: you have a few hours of rest ;)
<popolon> do you suggest I should addd : « the file name should start by the family of your SoC, like sun5i, sun6i or sun7i », simply
<mripard> Turl: actually, it's <family>-<soc>-<board>
<popolon> ok
nove has quit [Quit: nove]
<Turl> mripard: ah, right
<popolon> 806 files
xavia has quit [Quit: Leaving.]
<Turl> mripard: do you know if just pulling mplayer in will be ok, or do I need to enable codecs separately?
<popolon> Updated it : Identify the dtb file for you board in arch/arm/boot/dts, you will need it in the next step. The name of the file is constructed in <family>-<soc>-<board>.dtb form, so the filename of your board should start by it's SoC family like sun5i, sun6i or sun7i.
