TheLinuxBug: I also have my C.H.I.P. shipped from HK
<MoeIcenowy>
It's said to be shipped from June 22, but now the tracking status shows still that it's located in HK
<MoeIcenowy>
wens: I found that, according to the register name, AC100 seems to have some relation with A33/64 audio codec
<MoeIcenowy>
(so does AXP818 audio codec

wens: I think A33 CPUFreq should be added to mainline dts
<MoeIcenowy>
I mean dtsi
<MoeIcenowy>
so does A23
<MoeIcenowy>
as A23/33 is usually used on tablets
<MoeIcenowy>
CPUFreq means not only thermal throttle but also power saving
<MoeIcenowy>
how to add cpufreq support to dt?
<MoeIcenowy>
I tried to add clocks, clock-latency, operating-points to cpu@0 node in sun8i-a23-a33.dtsi
<MoeIcenowy>
added assigned-clocks, assigned-clock-parents to ahb1 ( according to a20/31 dtsi)
<MoeIcenowy>
and cpu0.cpu-supply to sun8i-q8-common.dtsi
<MoeIcenowy>
it doesn't work...

libv: I am interested in your lima driver. Apparently you showed some code at FOSDEM '14 but you hadn't released it or something?
<integfred>
libv: or is all the code you have on the driver released?
<wens>
Dodger78_: both drivers have been merged

Dodger78_: iirc spdif is also enabled on the cubietruck

kaspter has joined #linux-sunxi

Dodger78_: did you enable the driver? did you update the dts?
<wens>
check /proc/asound/cards
NiteHawk has quit [Remote host closed the connection]

im not 100% sure about the dts , i got a kernel of tag 1.7
<Dodger78_>
date
<wens>
for i2s you need to edit the dts yourself
<wens>
i2s is only the interface, you still need to pair it with a codec
<Dodger78_>
ahhhhh ! this is the info i needed
<Dodger78_>
is there documentation anywhere for it ?
<wens>
as for spdif, not sure if dapm (?) is disabling the output until you actually play something
<wens>
Dodger78_: not that i know of. what codec are you using?
<Dodger78_>
dont know , i expected that when i do a normal audio playback ( my cubie is also a sound server via mpd ) that spdif would play the same stream
<wens>
that is not how alsa works
<wens>
audio is only played to the "default" soundcard
<wens>
which would probably be the internal codec
<Dodger78_>
sorry im not a audio specialist , do i need to choose the "spdif" soundcard
<wens>
yes you do
<wens>
i don't remember the alsa conf settings, but most audio players let you specify the output device
<Dodger78_>
ah ok, and then it should be working ? where can i switch / assign the card ? alsamixer ?
<Dodger78_>
found a entry in my mpd.conf which i need to switch i guess

ssvb: just managed to convince the SPL to load a FIT image - with multiple binaries
<apritzel>
from both MMC and SPI NOR flash
<apritzel>
so I can load U-Boot and ATF
reinforce has joined #linux-sunxi
<apritzel>
also other images like a kernel or initrd
IgorPec14 has quit [Ping timeout: 252 seconds]
<apritzel>
now we are just missing the DRAM bits
<aalm>
for?
<Amit_t_>
FIT image include all the Images(ATF , U-Boot, kernel and initrd) ?
<NiteHawk>
aalm: for building a complete U-Boot (SPL) without having to link against the binary-only libdram
p1u3sch1 has joined #linux-sunxi
<apritzel>
NiteHawk: eventually yes, for the time it's still using libdram of course
<apritzel>
aalm: for the Pine64
<aalm>
ic, cool :)
<apritzel>
in the moment the SPL on Allwinner boards just load U-Boot, nothing else
<aalm>
i actually came to ask when to expect eth support in the mainline u-boot for pine64p
<apritzel>
aalm: it's kind of working already
* vagrantc
is excited to see what the pine64 support will look like in two weeks
<apritzel>
thanks to Amit_t_
<apritzel>
aalm: I will try to clean it up and post something
<apritzel>
problem so far was that we need to load and run ATF _before_ running U-Boot
<Amit_t_>
ok with FIT Image , its not required ?
Amit_t__ has joined #linux-sunxi
Nacho has quit [Ping timeout: 276 seconds]
<apritzel>
no, FIT image allows multiple images to be bundled together and loaded at different locations
Nacho has joined #linux-sunxi
<apritzel>
that's what we need
Amit_t_ has quit [Ping timeout: 250 seconds]
<apritzel>
and that's what Allwinner's boot0 does: load ATF, load arisc, load U-Boot, jump to ATF (which drops back to U-Boot)
<BenG83>
sounds great :)
<apritzel>
the classic SPL on sunxi can only load a single (legacy U-Boot) image and jump to it
<BenG83>
would it be possible to trace what libdram does via JTAG?
<apritzel>
why would you do it? You can just disassemble it ;-)
<BenG83>
right
<apritzel>
actually I started this already (about 40% through)
<Amit_t__>
but order of execution would remain, right ?
<Amit_t__>
*would remain same
<apritzel>
yes, though we can now easily change this if we want
<Amit_t__>
ok, it would now speed up the process.
<Amit_t__>
Thanks

apritzel: Could you please provide the filesystem you use for guest on pine64(I tried to use host filesystem but some how its not getting me prompt)

the host one should work, you may have to adjust the serial console though
