<Tenkawa> greetings all
<Tenkawa> so far so good on linux-next
<Tenkawa> anyone worked on audio with it yet?

<Wizzup> hiya
<Tenkawa> Wizzup: well.. 3.19 is running great
<Tenkawa> this box is much happier with newer code
<Wizzup> linux-next?
<Tenkawa> yea
<Wizzup> I also compiled a kernel yesterday, for snow
<Wizzup> didn't get the chance to try it yet
<Tenkawa> mine is working great
<Wizzup> sound?
<Wizzup> (jw)
<Tenkawa> thats what I'm going to be working on today because for me.. not so far
<Tenkawa> I figured out kb and mouse
<Wizzup> and wifi, display, usb?
<Wizzup> that worked last time I tried, so assuming it still works :)
<Tenkawa> had to get through the /sys filenaming
<Tenkawa> yeah wifi screen and usb are fine
<Tenkawa> I'm typing from mine right now
<Tenkawa> 3.19.0-next-20150211
<Tenkawa> sound is the only major thing (for me) that I havent quite finished with yet
<Wizzup> yeap, major for me too
<Tenkawa> do you know offhand which chip it is>
<Tenkawa> that will help me isolate it in testing
<Tenkawa> found it
<Tenkawa> now lets see if I can get a driver to talk to it
<javier__> Wizzup, Tenkawa: both speakers and headphone audio playback is working on peach pit/pi with patch https://lkml.org/lkml/2015/2/6/495 + the correct UCM profiles (I didn't post them yet)
<javier__> audio capture is not working though
<javier__> but audio on snow did not work for me even with the mentioned patch and a correct (afaict) UCM profile
<javier__> so there is something missing in mainline and I still didn't figure out what is
<Tenkawa> I'm trying some experiments noew
<javier__> Tenkawa: what experiments ooi?
<Wizzup> javier__: cool!
<Tenkawa> trying some tuning with tracing the input/output commands too see if thats where they might be "off"
<Tenkawa> mouse/kb were moved around for X so i wouldnt be surprised at all
<Tenkawa> brb need a reboot

<Tenkawa> ok experiment time
<Tenkawa> does the dtb have everything needed already btw
<Tenkawa> ?
<javier__> Tenkawa: no, I mentioned a patch above
<Tenkawa> can you repaste?
<Tenkawa> I lost my scrollback
<Tenkawa> thanks
<Tenkawa> ahh so it was dts related
<Tenkawa> hrmmm....
<Tenkawa> I already see one major difference
<Tenkawa> chech thids out
<Tenkawa> sound {
<Tenkawa> compatible = "google,snow-audio-max98095";
<Tenkawa> samsung,model = "Snow-I2S-MAX98095";
<Tenkawa> samsung,i2s-controller = <&i2s0>;
<Tenkawa> samsung,audio-codec = <&max98095>;
<Tenkawa> };
<Tenkawa> thats the sound chunk from my dts
<Tenkawa> not DAISY anymore
<Tenkawa> like your patch has
<Tenkawa> brb... need to run to another floor..
<Tenkawa> back
<javier__> Tenkawa: right, that was at typo I noticed after posting since I was using the ChromeOS UCM profiles and the amixer cdev:hw should match
<Tenkawa> trying another experiment
<Tenkawa> brb
<javier__> Tenkawa: this is the right patch https://lkml.org/lkml/2015/2/6/532

<Tenkawa> device/mixer coe up but no noise
<Tenkawa> ercome
<Tenkawa> er come
<javier__> Tenkawa: yep
<Tenkawa> I think thesse are the relevant bits

<Tenkawa> is that what you were getting?
<Tenkawa> wth
<Tenkawa> aumix makes "some" noise adjusting it
<Tenkawa> only with the mixer however...
<Tenkawa> thats got me an idea
<Tenkawa> ok so /dev/mixer is working just fine
<Tenkawa> btw I am having a lot of fun.. I really miss doing this
* Tenkawa is a dba nowadays.. spent most of the first half of his career as a sysadmin and dev
<javier__> Tenkawa: yes, I believe the problem is clock related because the downstream daisy_max98095 driver has some clock management that the snow sound in mainline doesn't
<Tenkawa> i agree
<Tenkawa> should I try to pull some of that from the 3.8 tree
<Tenkawa> and experiment?
<Tenkawa> I dont know devicetree well yet howeer quite willing to experiment
<Tenkawa> haaahaa
<javier__> Tenkawa: same for the dts since it grabs a lot of clocks while the mainline driver only gets the master clock from Exynos SoC XCLKOUT output pin (mclk)

<javier__> Tenkawa: I need to dig further on that to understand what's missing in mainline...
dlan has joined #linux-exynos
<Tenkawa> ok
<Tenkawa> if there is anything I can help with let me know
<Tenkawa> leave me a msg through nickserv
<javier__> Tenkawa: I will, thanks
<Tenkawa> sure thing
<Tenkawa> like I said.. I'm really having fun
<Tenkawa> again
<Tenkawa> I've missed this
<Tenkawa> brb.. trying another crazy experiment
<Tenkawa> I'm going to get my other computer out I think so I can have one sitting on irc while I reboot 500 times
<Tenkawa> haahaa

<Wizzup> javier__: Correct UCM profiles would be welcome
<Wizzup> Once you get around to post them somewhere
<Wizzup> I'm on my snow again and forgot about the errata's from last time
<Wizzup> I guess the first thing to do is to get a mainline u-boot on there
