morning, yesterday we talked about new mali blobs and if there is a possibility to get new ones (e.g. r3p2-01rel2) as there is a new mali sdk v2.2 out, too.
<rellla>
waht do you think?

hno how do I use i2c on our boards, on the A20 i get 'i2c probe' then nothingness

hello
<hramrach_>
oliv3r: I checked out the cubieboard jellybean repo and replaced the kernel with the linux-sunxi kernel
<oliv3r>
oh nice one
<hramrach_>
and when I did it would not build with the prebuilt andriod tools
<hramrach_>
you can use andriod tools to build andriod and emdebian tools to build kernel
<hramrach_>
not sure it boots. The build spits out a livesuit image (presumably) but I have no livesuit
<hramrach_>
also I winder where it takes the fex when building
<hramrach_>
there are like 3 of them somewhere in the repo
BJfreeman has quit [Quit: had a good time]
<oliv3r>
mripard_: got a moment?
<oliv3r>
does anybody have a a31 fex file?

i'm curious how the dram_para field looks like now, if its still the same or not

<andoma>
I remember when hacking A10 for a while ago (6 months?) that there were problems with displaying a full screen alpha blended opengl surface ontop of video output in 1080p60. It caused tearing or what looked like buffer underruns during picture scanout
<hno>
can't comment on kernel support just yet, but 3.4 will come, and also quite hopeful that mainline support for a20 is also coming.
<hno>
oliv3r, have you read the changes an extra time?
n01 has quit [Read error: Connection reset by peer]
<bfree>
hno: yep, thanks, I noticed it was also syncing up to denx master, hence wondering if I could pick it across to add to my sunxi-current based package pending it getting the support itself (new cubie2 here, just trying to decide what to do with it first and obviously I'd "just" like to update my packages)
<oliv3r>
hno: i may have not pushed yet
<oliv3r>
hno: going over github now to double check
<hno>
oliv3r, that commit is there. Just wondering if you have manually read the changes one extra time?
<oliv3r>
reading it now
<oliv3r>

building andriod SD card
<hno>
oliv3r, I think you have mixed up DRAM_DLLCR_RESET and DRAM_DLLCR_RESET.. mctl_enable_dllx makes no sense, leaving the state as !ENABLED, RESET
<hno>
Makes sense if the bits are DISABLE and nRESET
soul has joined #linux-sunxi
<oliv3r>
hno: the debian paste is from the code I mentioned in my email
<hno>
That code is what tom wrote for the SPL. #ifdef:ed out in aw u-boot.
<hramrach_>
heh
<oliv3r>
could be it exists there aswell
<ssvb>
andoma: nobody knows for sure what is the root cause of this shaking screen effect, but it indeed looks like the scanout is getting starved and does not have enough memory bandwidth
<oliv3r>
as i said in my email; it may not work at all
<hramrach_>
is there an andriod application similar to cu?
<oliv3r>
hno: so rename it to NRESET?
<hno>
and DISABLE.
<hramrach_>
I would like to see serial output without running a pc
<oliv3r>
rgr
<hramrach_>
and initial image is probably android
<hno>
hramrach_, then you need something else with a UART that can read the output..
<oliv3r>
now i'll probably have to break my own git with a froced push, since i branched a tree off of my wip/a20 :)
<ssvb>
andoma: reducing refresh rate, reducing color depth, reducing resolution, enabling "scaler mode" and overclocking dram helps
<hramrach_>
it won't have the serial uart driver anyway
<hno>
hramrach_, what?
<hramrach_>
USB serial
rz2k has quit [Read error: Connection reset by peer]
<hramrach_>
the andriod image
<hramrach_>
they have no drives, ever
<hramrach_>
so no point getting applications for them :/
<hno>
there have been some serial drivers in the Allwinner images I have looked at. And easy to build your own image with more drivers if needed But I don't use Android.
<hramrach_>
easy to build ..
<oliv3r>
nRESET or RESET? (lowercase in a define looks iffy)
<oliv3r>
nRESET or NRESET*
<hramrach_>
when it comes to building imges it's easier and more useful to build Linux
<hramrach_>
now I have something that is Android and *should* boot on cubieboard unless broken
edeloget has joined #linux-sunxi
<hramrach_>
oliv3r: NO_RESET ;-)
hipboi has quit [Quit: Leaving]
<hno>
oliv3r, pick one. But signal name in hardware designs is nRESET
<hno>
or #RESET depending on notation. But here it does not matter.
<oliv3r>
i'll use NRESET to stay with the capitals for defines rule
<oliv3r>
_!RESET :D
<hramrach_>
does that work as define?
<hramrach_>
NRESET is somewhat unintelligible
<hramrach_>
does it mean number of resets?
<hramrach_>
not that the original nRESET is better
<hramrach_>
it's quite likely that nRESET will be challenged by some nitpicker
<hramrach_>
but until it is at least it matches the docs
<oliv3r>
not really an issue with u-boot i suppose; but yeah it should be nice
<oliv3r>
we have no docs :)
<hramrach_>
or schematics or whatever
<hno>
hramrach_, these are internal signals within the SoC, in a part for which we do not have any docs what so ever other than some random pieces of code..
<oliv3r>
hno: anyway, is it worthy for the ML to submit for review? or do i need to hack more on it
<hramrach_>
hmm, I have some drm error

rellla2 has joined #linux-sunxi

<hramrach_>
anyone has a tip for fast USB SD reader?
<hramrach_>
the a10 mmc tops at ~ 10MB/s but the USB card readers I get with some cards top at ~ 2MB/s
<hramrach_>
a built-in card reader in a Dell desktop does ~12MB/s so it's possible to improve
<hramrach_>
it's hdparm readonly numbers so not exactly awesome benchmark but still much difference

<oliv3r>
techn_: you finally got it?
<oliv3r>
still nothing here :(
<oliv3r>
hno: i'll send it off to the ML then; i'll be identifying more bits with a 2nd patch; then we can start looking at restructuring
<oliv3r>
i have a few idea's too

but i think a31 support would e nice to have first

ssvb: there is simething wrong with blending of some windows in gnome
<hramrach_>
when I select profile preferences in Termainal and set color the color seems ok in color picker but blueish in hte preferences dialog

eg. green in color picker becomes cyan in preferences
<hramrach_>
ok, I don't have teh latest driver so I guess I could try upgradeing, too
<hramrach_>
actually, the terminal itself looks odd too but that might be gnime default terminal palette
<techn_>

<techn_>
lucky you ;)
<hramrach_>
lucky you :)
<techn_>
it would be perfect weather if you have air condition :p
<hramrach_>
it is like 3 days a year on average so nobody has air conditioning for that
<hramrach_>
and when you have air cinditioning weather is irrelevant overall
<hramrach_>
plus it still sucks to go out into that even when you do have air conditioning
<techn_>
quite many ppl has air condition here in finland.. during hotest days (30C) it cools and between -20 - +20 it saves electicity
<techn_>
well it's not full air conditioner.. bu "air-source heat pump"
<oliv3r>
hno: what other values have you seen? All A10 boards in git have zq = 0x7b. A20 has 0x7f as the only one. So again reg_val = ((para->zq) >> 8) & 0xfffff;
<oliv3r>
makes absolutly no sense to me
<oliv3r>
so I must overlook something, I just don't know what

<mripard_>
Turl: your magnet doesn't work really well I'm afraid :)

mripard_: are you or someone else planning to start it?
<mripard_>
yeah, somewhere around this week end
<techn_>
ok.. great.. first impression is that it is simple? :)
<mripard_>
I have put all the patches out of my queue and in 3.11, so now, I'll be able to focus on A20, A31 and SDIO
<hramrach_>
soul: you can boot from SD card
<mripard_>
techn_: it looks like an A10 with 2 cores and a GIC instead of allwinner's interrupt controller
<mripard_>
we already have a gic driver in the kernel
<mripard_>
so I think I can have some patches working very quickly
<soul>
hramrach_: But It will load the distro instead of android?
<mripard_>
however, it won't be smp at first
<hramrach_>
it wil load whatever is on the sd card
<soul>
Ohm... hramrach_, ok thanks
<oliv3r>
mripard_: you got a few
<mripard_>
oliv3r: a few what?
<oliv3r>
single core a20 will be good

pm
<mripard_>
ah
<mripard_>
yeah, dual core will come later

I'm pretty sure it will trigger some additionnal problems we didn't catch before

<drachensun>
if so I honestly can't see how its different from fex
<oliv3r>
but its harder to actually write i suppose, so you have to know what youa re doing?

seems like an easy conversion

not again the fex vs dt thing :p

I'm not arguing
<mripard_>
drachensun: it's similar to some aspect
<mripard_>
well, at least, the idea is the same

I was a little curious what all the fuss was about, again given how it appears to be almost the same, just a question of the data format it seems to me
