naobsd, ping.
<Tony_>
naobsd, I found the real problem of Audio.
<naobsd>
info about bootable SD/eMMC layout is described some by field^Mop
<naobsd>
it's not perfect, but there is some info. he tried to delete it and and try to blame me "no info!"
<naobsd>
Tony_: good news :)
<Tony_>
naobsd, pulseaudio can't set Playback as "SPK" or others.
<Tony_>
naobsd, with AlsaMixer, can set Playback as "SPK" or others.
<naobsd>
hmm
<Tony_>
naobsd, with pulseaudio, the Playback is always 'OFF', so ...

mrcan_ has quit [Remote host closed the connection]
<Tony_>
naobsd, anther problem about Audio is that the kernel register two cards.
mrcan__ has joined #linux-rockchip
<Tony_>
naobsd, RKRK616 and ROCKCHIPSPDIF.
<Tony_>
naobsd, the 2th is fake card, which can't get asound control.
levd1 has quit [Ping timeout: 240 seconds]
<Tony_>
naobsd, the first one is real one which can works fine.
<Tony_>
naobsd, but sometimes, the pulseaudio out put audio into the fake card ROCKCHIPSPDIF.
<naobsd>
I think there are some audio output on RK SoC
<naobsd>
I'm not sure that's really fake, but I can understand
<Tony_>
naobsd, yes, i think so. but we only use RK616.
dlan is now known as dlan^

<Tony_>
naobsd, remove ROCKCHIPSPDIF card in kernel.
<naobsd>
some more detail about SD/eMMC layout can be found in RK u-boot source
<naobsd>
I have no idea why he blames me
<Tony_>
naobsd, who blames you ?
<hramrach_>
naobsd: you were always concerned about the wiki containing errors and not about lack of information
<naobsd>
Tony_: maybe good for your board. then pulseaudio works fine?
<hramrach_>
now the page should be to your liking
ganbold_ has quit [Ping timeout: 272 seconds]
<hramrach_>
naobsd: and if you do not want to fix the wiki do not edit it either
ganbold_ has joined #linux-rockchip
<hramrach_>
also reverting the page to the worst historical version we had
<Tony_>
naobsd, yes, after I check "Playback Path" to "SPK" or others, then the pulseaudio can works fine.
<naobsd>
hramrach_: thank you. I want to fix wiki. I'll discuss about it.
<hramrach_>
if it was someone clueless I could understand
<hramrach_>
but if you place intentionally wrong information on the wiki that's trolling
<hramrach_>
same when I do one line change and you notice it's wrong, notice I did it, notice I cane on irc and tell me it's wrong but not tell me what's wrong with it nor fix it yourself
<hramrach_>
like software documents can have bugs and to be fixed at least useful bug reports are needed. not whining it's wrong
levd has joined #linux-rockchip
<hramrach_>
also since there was no agreement empty page would not be in favour of any broken version and we could discuss each piece of content we put on the page rather than start with tons of useless repetitive babble
<hramrach_>
but whatever

Astralix1: did you try mainline kernel on your RR pro, btw ? (it works fine now here, my uart debug is not very stable but it's my usbttl converter I think or my wires... electrically everything looks good)

rperier, I have used three different dongles on three different rocks. The scope screens I shot where from two different rocks, each without any dongle connected.
<AstralixNB>
So the defective roch shows a diffrent behavior than all others without any dongle involved. I will exchange the protection diodes at the pins and then check again.

dump question... if I have an image of a single partition, I can mount it via mount. But how to mount an image, that contains multiple partitions?
<lioka>
usually kpartx -av path/to/image.file
<lioka>
and mount whatever partition you interested in
<lioka>
but with rk i'm not sure in anything ??
<lioka>
:]
<AstralixNB>
no, it is a forensics thing with a wand board (iMX)

that's just to know if you paid customs duty

(or if someone who applied for "giving away" program paid for customs duty)

it depends on the company who ships the package probably..

I have a question about the way I could shortcut the access to closed drivers...
<AstralixNB1>
If I design a driver, I can prepare a header file. With that header, other programs know how to access my drivers functions.
FreezingCold has joined #linux-rockchip
<AstralixNB1>
In case I ship only a closed source driver, other people can still use my driver as they know the function calls.
<AstralixNB1>
Is this correct so far?
<mmind00>
hmm, not sure ... kernel <-> userspace interaction normally doesn't work via header files I think
<mmind00>
[if this is what you mean with "other people can use the driver"]
<mmind00>
but for in-kernel users this should be mostly correct
<AstralixNB1>
Ok, so that is the problem I actually face
<AstralixNB1>
In case of the userspace drivers, they provide function calls in set of streams and io functions.
<AstralixNB1>
so you don't have any header files, but predefined iocalls.
<AstralixNB1>
Is it possible to fetch these iocalls in any automated way? Or are the only two ways documentation or disassembly?
GriefNorth_ has quit [Ping timeout: 272 seconds]
<mmind00>
the only kernel <-> userspace interaction I have touches myself, were the ioctls of the imx epaper driver ... and there the constants defining the ioctl number where exchanged via a header
<mmind00>
ok ... so there will often a header in use but mostly for defining these ioctl data
<mmind00>
[just remembering this piece by piece :-) ]
<AstralixNB1>
I am talking about RK drivers exporting VPU and other functions as userland drivers
<AstralixNB1>
I am pretty upset with this tons of work trying to find out which call has been changed where in Android. RK is changing things with every release, google is changing things with every release...
FreezingCold has quit [Quit: Out]
FreezingCold has joined #linux-rockchip
<mmind00>
I always try to stay as far away as possible from such userspace interaction ... so I probably won't be any help here
<AstralixNB1>
AS you might see from my queystion, I have sucessfully kept a wide distance beteen me and such things too... Unfortunately sometimes these things speed up fast and catch you
<AstralixNB1>
would be nice if someone reading this could explain it to me
BorgCuba has joined #linux-rockchip
<AstralixNB1>
ok, a different question...
<AstralixNB1>
ION is a android special memory allocator?
<AstralixNB1>
I wonder why it is delivered as a closed .ko instead of an open source kernel module... There should not be any secrecy inside...
