<cubeast>
this page does not describe that stage branch
<libv>
cubeast: people have recently been concentrating on mainline development
<cubeast>
I know, but I need video acceleration
<libv>
guys like mnemoc and i are not working for companies who support sunxi development, and are too busy to spend time on it
<cubeast>
I'll gladly use the mainline for all my headless systems
<libv>
cubeast: why do you ask for this difference?
<libv>
what problem are you trying to solve?
<cubeast>
I'm curious whether the staging branch is a better choice with more support
<cubeast>
the wiki page doesn't say anything about it, and the github shows it's more recent
<cubeast>
than the standard sunxi-3.4
<libv>
then try it
<libv>
i doubt that it is very far ahead of sunxi-3.4

Can I ask one stupid question regarding NAND/eMMC replacing? eMMC is a chip right? Why is then SD card adapter used for?

so I wired it to a SD adapter to confirm that I have do wire right

libv:It seems that the Allwinner is preparing for A64
<rgwan>
I think that the A80 is totally a fault on Allwinner
<rgwan>
The hi-performance processor is locked by Intel
<rgwan>
A80 has very big heat produce
philippe_fouquet has quit [Remote host closed the connection]
<libv>
rgwan: a80 was a dud, as was a31 :)
<libv>
allwinner really is not doing well with sgx based devices
<rgwan>
Yeah
<libv>
not because of sgx though
<rgwan>
Oh. How about mainline kernel with dualcore MELE A100
<rgwan>
I dont know how to setup VGA out
<rgwan>
(It is A20 based device)
<NiteHawk>
isn't Mele A100 based on A10?
<libv>
doesn't work with the mainline kernel, but you should get simplefb when you set up uboot right
<wens>
wonder what part of the a80 generates more heat, the cpu clusters or the gpu
<rgwan>
I think is the A15x4
<rgwan>
NiteHawk:No. mele a100 has a dual core version
<rgwan>
based on A20
<libv>
rgwan: do we have that one documented on our wiki at all?
<rgwan>
but only sold for few month
<rgwan>
what?
<libv>
the dualcore a100
<rgwan>
no
<rgwan>
But I have get one
<NiteHawk>
wiki forwards to A1000, and doesn't connect with A20 there...
<rgwan>
You can see it on my blog
<rgwan>
This version didn”t sell for long time
<rgwan>
In my memory just half-year
<rgwan>
maybe short
<rgwan>
libv: The lima driver still can”t use stably?
<libv>
?
<libv>
lima is not a display driver.
<libv>
nor a media driver
<rgwan>
Oh?
<libv>
nor a 2d driver.
<libv>
it's actually not a 3d driver yet, at least not what is out in the wild already
<libv>
rgwan: those are all different parts of what used to be on a graphics card
<libv>
but they are different blocks on an SoC
<rgwan>
So A10/A20 just leak some driver for 2D display?
<libv>
not leak
<rgwan>
Okay
<rgwan>
?
<NiteHawk>
s/leak/lack/
<libv>
there is a horrid display driver in the allwinner codebases
<libv>
and there is a kms driver which i also haven't thrown out yet
<libv>
but there is some code in uboot which initializes the display engine
<rgwan>
Oh my god
<libv>
?
<rgwan>
I think just like the FTL-NAND driver
<rgwan>
Allwinner doesn”t comply to the standard?
<libv>
rgwan: anyway, please follow the new device howto to get devices in our wiki
dlan has quit [Ping timeout: 272 seconds]
<rgwan>
Okay
<libv>
if they are on your blog, it only reaches a few people
<libv>
and the chance is higher that the information will vanish
<rgwan>
Yes
dlan has joined #linux-sunxi
<libv>
i will be happy to assist you into getting devices in our wiki
<libv>
but we cannot go plucking random information from the interweb, the owner (or owners) of the hw needs to go do the work and make sure that everything is correct
<rgwan>
I will do it tomorrow
<rgwan>
Yes
<libv>
it's not life-or-death, but it's best done when the information is still fresh
<rgwan>
bacause in my place it”s 21:46 now
<rgwan>
I agree
<rgwan>
Uh you said KMS driver for AW disp?
<libv>
i had a talk about it at fosdem 2014
<libv>
it is/was pretty advanced, but lacked LCD/LVDS
<libv>
and then in 2014 i didn't do code much
<libv>
cfr my latest blogpost :)
<rgwan>
Yeah...If I have spare time on this summer I will help you
<rgwan>
I want to use mainline kernel for desktop use
<rgwan>
My mele i7 just to be a server
<rgwan>
Mele A100 DC will be a slave desktop
<rgwan>
I think at least this box has to support VGA display
<rgwan>
and SoC Codec

Hopfully I can give a comfortable disp driver on the summer ends

what's the mainline u-boot thats patched to support booting from nand? This? git://git.denx.de/u-boot-sunxi.git

libv, oh, you already had a proper KMS driver? bbrezillon also started one but didn’t go very far, and I wanted to make one too but got hired to work on something else instead.
<linkmauve1>
Do you still have plans for a release, even if it still doesn’t support LVDS and LCD?
<linkmauve1>
I think, even putting your tree on some random repository would be useful, even if you don’t make it a proper release.
<libv>
linkmauve1: check my latest blog entry
<linkmauve1>
Sadly I didn’t bring any of my Olimex boards in UK. :/
<libv>
linkmauve1: i have been taught, and get taught, not to release code or ideas, or fundamentally change things, time and time again
<libv>
i am hard of learning though, and now i just am not too motivated to work on what i have been working on before
<linkmauve1>
That’s even more of a reason to actually publish it, so other people can continue your work for you.
<libv>
nope

libv, I just read that blog post, but I don’t understand your two choices at the end.
<linkmauve1>
Obviously, since they have used the blob they won’t be able to contribute/use lima again.
<linkmauve1>
And having people who contribute doesn’t change the attribution of any prior code, you know that.
<libv>
linkmauve1: i know that that is not true.
<libv>
cfr modesetting or radeonhd.
<linkmauve1>
Besides, a less-than-perfect open driver is imo much better than no driver at all, and be stuck on ARM’s 3.4 driver forever.
<libv>
you are just saying that for selfish reasons.
<linkmauve1>
Probably, the selfish reasons of the community as a whole.
ninolein has joined #linux-sunxi
<libv>
so i, who wasted time on this, am not allowed to be so selfish as to keep the code i wasted time on to myself?
ninolein_ has quit [Ping timeout: 252 seconds]
<linkmauve1>
Sure you are, but earlier you talked about “open drivers”, which doesn’t make sense with something unavailable to anyone but yourself.
<libv>
linkmauve1: all i see is selfish demands or crap throwing
<linkmauve1>
There is no obligation at all to release anything you have done, I also have that bias to hold on publishing piece of code I don’t consider good enough btw, but I think it’s still better to share early than to share never.
<libv>
linkmauve1: and i made lima code available till oktober/november 2014, the last time i went and cleaned up my codebase
<libv>
i'd say that that is far ahead of most people in this universe
<linkmauve1>
I thank you for having done that, I already have used it quite a bit. :)
<linkmauve1>
I just hoped, back in January 2014 when I bought those Olimex boards, to be able to run them on a fully free graphics stack someday.
<linkmauve1>
I’m also glad for the work you and everyone else did on linux-sunxi, which is obviously another thing that was missing towards that goal.
hero616 has joined #linux-sunxi
leviathanch has joined #linux-sunxi

But that’s why I think it’s sad to stop there and not release your work that is nearly finished, that would be a huge improvement towards that.
<libv>
it's sad, yes
<libv>
it's sad that open source software has nothing to do with code or technical excellence or doing the right thing.
<linkmauve1>
Like anything else, indeed. :(
