Looking for a test newer Cubieboard2 kernel with mmc and hopefully usb support. Should I be looking at sunxi-next, sunxi-devel, or a jwrdegoede/* kernel? Any good .configs?

kenny: jwrdegoede/sunxi-devel
<kenny>
wens: thanks. How about configs?
<wens>
none, use the defconfig and add the drivers you need (ahci / ohci / ehci / mmc)
<kenny>
wens: sunxi_defconfig I take it? Any can you help with how I figure out which mmc drivers I need?

Also I see A10 EMAC support, but nothing saying A20. Does this tree have A20 ethernet support?
<wens>
use stmmac platform driver (i tihnk it's under STMicro) with Sunxi support
<wens>
mmc driver has allwinner or sunxi in the title
<kenny>
wens: excellent, thank you.

wookey: in case nobody redirected you; checkout linux-sunxi.org that's our wiki which should have the most up to date information :)
<wens>
and maybe the ohci/ehci platform patches from hans (or you could wait until all of his usb work is accepted)

oliv3r: I've been looking there and found good info on building kernels and which kernel to use (I aldready editied a link :-) But I didn't find good info on the bootloader setup and methods for that board.
fredy has quit [Excess Flood]
<oliv3r>
wookey: well there's u-boot sunxi which only works on mmc; which is what nearly all of us use
<oliv3r>
and for NAND use, just keep whatever is pre-installed
juanfont has quit [Read error: Operation timed out]
<wookey>
OK. right - that's the sort of clue I was looking for. I guess mmc-boot is useful while devloping. But nand-boot is better for server usage.
fredy has joined #linux-sunxi
<oliv3r>
if your nand keeps working that long; sure
<wookey>
I don;t write new kernels that often :-)
<oliv3r>
what about the OS?
<oliv3r>
won't that write? swap?
<Nyuutwo>
wookey: rootfs? swap?
<oliv3r>
installing updates etc
<Nyuutwo>
or you make use of some kind of ro nand rootfs with tmpfs?
<wookey>
fine with a sensible FS like yaffs
<Nyuutwo>
overlaid
<oliv3r>
wookey: you can't use yaffs on nand
<wookey>
what? That's what it's for
<oliv3r>
it's ablock device, so only things like ext4; f2fs might work; but i don' tthink you gain anything significantly due to the crappy driver
<oliv3r>
wookey: on 3.4 kernels, nand driver isn't a mtd driver, it's a blockdevice driver
<oliv3r>
yaffs2 requires a mtd driver to be undernearth
<wookey>
you mean the nand on the device is not exposed as MTD device?
<oliv3r>
that said, the chip might not even do yaffs2; atm we're limitted to ubifs
<oliv3r>
and mtd stuff hasn't even been merged yet
<oliv3r>
wookey: exactly
<wookey>
So the nand is actually presented effectively as built-in mmc?
<wookey>
with a controller of unknown smarts i the way
<wookey>
that's not very helpful
* wookey
needs to catch up on the details some more
<Nyuutwo>
wookey: it is not smart afair
<Nyuutwo>
it just supports some partition info + randomizing
<wookey>
samsung did a driver for MTD-as-block
<wookey>
I forget the name.
geecko has quit [Quit: bye bye]

<oliv3r>
wookey: no it's not :)
<oliv3r>
wookey: you get the full flash controller, that's normally embededed into a (e)MMC
<oliv3r>
but we have a crappy driver (libnand) that exposes it as a block device, and does wear leveling etc
<oliv3r>
and there's people working on an MTD driver

oliv3r: and how is DMA?
<Nyuutwo>
afair nand depends on dma

<oliv3r>
Nyuutwo: we have PIO right now
<bbrezillon>
Nyuutwo: Hi, I'm the one currently working on the NAND driver, and for the moment it does not depends on DMA (I might add support for DMA transfers later)
<oliv3r>
we need dmaengine first anyway :p
<wens>
ccaione: what function on AXP do you plan on doing next?
<ccaione>
wens: I have regulators in my repo but I want to wait for feedback on the core part before submitting it
<ccaione>
actually also the input driver wasn't mean to be submitted already :)
<ccaione>
one subsystem at time
<wens>
I was wondering if we added hwmon support, do we have to add it to lm_sensors as well?
<bbrezillon>
oliv3r: yes sure :)
<ccaione>
no idea
<oliv3r>
i guess it depends how it's exposed
<wens>
I might go do that if I get really frustrated with musb :/
<ccaione>
wens: btw if you have time, please, review my patches. (nobody seems ever to care about my patches :(( )
<wens>
Just the core?
<ccaione>
if you are willing also the input driver :)

ccaione: I think your patches should also include the copyrights from original driver from allwinner SDK
<ccaione>
plaes: my patches are totally different
<ccaione>
I wrote them from scratch
<plaes>
hmm.. ok
<plaes>
ccaione: the description in mfd/KConfig file is a bit too generic
<plaes>
I would add that it supports AXP209 (and AXP203?) chips which is commonly used together with Allwinner chips
<ccaione>
plaes: I'd like to avoid mentioning allwinner since the driver if fully generic
<plaes>
ok
<plaes>
link to the datasheet would be nice to have too
<ccaione>
I'll link the datasheet in the header and write a better description in v2
<plaes>
and it looks damn clean :)
<ccaione>
:D
<plaes>
if you really want something, then alphabetical order of includes is wrong :P
<ccaione>
hahaha I hate ordering includes, but ok, I'll fix in v2
<plaes>
this was in drivers/mfd/axp20x.c
<oliv3r>
ccaione: oh puneet.
<oliv3r>
just seeing his name makes me want to cry
<oliv3r>
did you see his 720p video mail?

i only saw now, that he was trying to watch quicktime/motion jpeg 2000
<ccaione>
I know nothing about what he keeps asking, just I cannot stand his attitude
<oliv3r>
i always read 'i'm an idiot, help me solve my shit'
<oliv3r>
but i try to be polite :)
<oliv3r>
heh, exynos 4212-g2d being upstreamed; i wonder how similar it is to our g2d
<plaes>
o_O
<wens>
ccaione: i would expand the bindings example
<wens>
the example doesn't list all the _required_ properties
<ccaione>
wens: yes, that's because all the other properties are defined by the dts file includind axp20x.dtsi
<ccaione>
but I agree, I'll extend the example
<wens>
I think you should list the i2c address, which i recall is incorrect in the datasheet
<ccaione>
wens: right, one more fix
<ccaione>
(BTW need to update the wiki)
<wens>
and the AXP20X define, is a bit ambiguous, the current code doesn't use it much
<popolon>
the pandora open source hw game console project is (eventually) interested by an allwinner A80 for the pyra handled
<popolon>
they don't seem to care about the closed powerVR driver and don't really know about the mali driver state (well the state of the driver is not updated often on the mali driver page)
<Nyuutwo>
do you know if #barebox@freenode is active?
HeHoPMaJIeH has quit [Remote host closed the connection]
<Turl>
popolon: wasn't that project a scam?
<popolon>
They made a conf at FOSDEM
<oliv3r>
well the whole dev-room talks gave me much hope
<Turl>
popolon: I recall reading some time ago that the dude never shipped all the hw and that sb else had come forward and made a different console and generously gave some to the affected people
<popolon>
didn't know about that
<popolon>
oliv3r, do you speak about mali dev-room or openpandora dev-room ?
<Turl>
popolon: well maybe openpandora is the good one. They both have similar names :\
<Turl>
in any case, it's great to have more people interested in AW hardware :)
<popolon>
allwinner is only an option for now, they think about qualcomm too
<popolon>
after a poll, bay trail seems to not be the best target (that was an option too)
<oliv3r>
popolon: mali :p
<popolon>
cool, libv sadely don't update very often it's blog or mali driver main page news
<popolon>
is the maliT6xx working ?
<oliv3r>
i don't think yet
<plaes>
nope
<popolon>
ok, probably, as openpandora people was at the fosdem too, they seen the graphics devroom too
<oliv3r>
i woudln't be overly sure of that
<oliv3r>
firefox people weren't even aware of the sunxi talk that I did, in the same building
<popolon>
I speak of this channel on #openpandora
<popolon>
They are aware that every FOSDEM conf will be available online...
<oliv3r>
officially, it's nto done yet
<oliv3r>
there's some audio issues that need to be resolved
