09:49 Z0l hello
09:50 rabeeh hi
09:50 Z0l can somebody help with debugging a HDMI issue with Cubox i4pro and a Sony 40W5500?
09:50 rabeeh go ahead
09:50 Z0l in short, I think the cubox fails to read the EDID and this causes stalls in the kernel
09:51 Z0l let me put the error on pastie, 1 sec
09:51 Z0l http://pastebin.com/0asdeYHx
09:52 Z0l what is also strange, that the error only happens if I switch the TV to the HDMI input the cubox is connected to
09:52 Z0l (I tried it with 2 HDMI cables and 2 different ports on the TV)
09:53 rabeeh which kernel?
09:53 rabeeh which distro?
09:53 Z0l sorry, this was geexbox 0802 nightly
09:53 Z0l that comes with 3.10.30 I guess, but let me confirm
09:54 Z0l I already tried geexbox, openelec and xbian, and both give the same error
09:55 rabeeh once you plug in it's panics?
09:55 Z0l Linux version 3.10.30 (martin@martin-VirtualBox) (gcc version 4.8.3 20140401 (prerelease) (Linaro GCC 4.8-2014.04) ) #1 SMP Sat Aug 2 20:07:44 EDT 2014
09:55 rabeeh 100% reproducable?
09:55 Z0l yes
09:55 Z0l actually it's not a panic, just a delay
09:55 Z0l so the machine is accessible via telnet/ssh/console
09:56 Z0l but I see nothing on the display
09:58 Z0l I guess it may have to do something with my TV as well (something like Sony's not passing over a proper EDID when queried), but I don't think the device handles this appropriately
10:00 rabeeh even if EDID is not parsed correctly; those distros have default (typically 1080p60)
10:00 rabeeh that rcu thing is very familiar
10:01 Z0l yes, 1080p60 is the default
10:01 rabeeh so it's not about edid parsing
10:01 rabeeh want to try another one?
10:01 rabeeh LK 3.0.35
10:02 rabeeh just to see if it's kernel related?
10:02 Z0l certainly, where can I download it from?
10:03 rabeeh http://download.solid-run.com/pub/solidrun/cubox-i/Debian/Jessi-repackaged-trial/debian-jessi-4-july-2014.img.xz
10:03 Z0l (in the meantime I started your 07-04 debian image that gives a working xfce at 1080p60 without any errors)
10:03 Z0l ah
10:03 rabeeh keyboard is UK by default
10:03 Z0l :)
10:03 rabeeh hehe
10:03 rabeeh so it's kernel related
10:04 Z0l can I replace e.g. geexbox's kernel with yours?
10:04 rabeeh nop
10:04 rabeeh jnettlet suggested to disable cpu_idle
10:04 rabeeh he thinks the rcu_ oops and panics are related to cpu_idle
10:05 Z0l can that be specified using a kernel boot argument or only once it's running?
10:08 rabeeh cpuidle.off=1
10:08 rabeeh ?
10:08 rabeeh please check; i'm just reading the from the kernel documentation
10:08 Z0l let me add that to uEnv.txt and try, 1 sec
10:08 rabee 10:08 * rabeeh disappears for 15m
10:08 rabeeh please spam my irc window
10:14 Z0l please let me know once you're back, unfortunatly the cpuidle.off=1 didn't do the trick
10:16 Z0l it did disable cpuidle, but the error is still present
10:32 rabeeh back
10:33 Z0l in the meantime I also tried geexbox with your kernel, it booted up and didn't give me error messages, but no xbmc either
10:34 rabeeh are you able to rebuild a kernel?
10:34 Z0l i have a debian running in a vm, but i don't have a working build environment
10:35 Z0l if you can point me to some documentation, i think i can do it
11:02 Z0l ok, i have set up my build environment
11:03 Z0l which kernel should i build? and with what patches/changes?
11:26 Z0l gotta go, will come back tomorrow
11:26 Z0l bye and thanks for the help
12:13 joost_dtn anyone here have any experience connecting an Apple Wireless keyboard via bluetooth to a Cubox-i2Ultra running latest Geexbox distro and the onboard bluetooth?
12:14 joost_dtn hcitool scan and bluetoothctl are not finding anything here
12:15 joost_dtn tried a bunch of wiki entries/forum suggestions but no dice
12:15 joost_dtn so i'm looking for some one that actually has the Cubox-i2ultra (not the i2ex) and an Apple Wireless keyboard to get some pointers
14:20 kgp @rabeeh: When do you expect an update of your image?
14:21 kgp Already 1month old....
14:21 kgp :)
14:35 KodiakF kgp: Came into this late - what image? (just being nosy)
14:36 rabeeh kgp: i can share if you promise to assist :)
14:36 kgp I would love to... in my limited experience :)
14:37 rabeeh kgp: oh; it's not limited :)
14:37 rabeeh i already know your capabilities
14:37 rabeeh anyhow; i have debian from sources
14:37 rabeeh thanks to mk01 debian packages; one script that anyone can add more
14:37 KodiakF oh debian
14:37 rabeeh shall i start a new github project?
14:38 rabeeh KodiakF: yeah
14:38 rabeeh potentially same sources can be RPMed
14:38 rabeeh i just had java 7 se running on that
14:38 kgp It could be a good idea (but I'm not an expert) ?
14:39 kgp Did you saw: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-arm-downloads-2187472.html
14:39 rabeeh it's a 100 lines of bash script that prepares an image
14:39 rabeeh yup; click on first link :)
14:39 kgp If we can help, finetune the script, I would love to add my small optimizations.
14:40 rabeeh kgp: exactly; that's what i need the help of the community with
14:40 rabeeh it's using LK 3.10.30 for now but will be moving to LK 3.14
14:40 rabeeh LK 3.14 already supports CBi and HB
14:41 rabeeh few tweaks are missing there too; but jnettlet is taking care of
14:41 rabeeh (hdmi-audio for instance)
14:41 rabeeh but it's a perfect script to start with and then can be expanded to install anything (even with ready to use image for specific use cases)
14:42 rabeeh for instance for desktop, thin client, headless etc...
14:42 kgp How is your issue with Mesa going?
14:43 rabeeh since i'm installing from latest debs; i'm not seeing that yet
14:43 rabeeh but mesa will be pinned
14:44 kgp I just bought a 128Go mSata drive ... so I have some space to compile things now ;)
14:48 rabeeh but first; working with jnettlet / rmk to finalize the kernel
14:53 kivutar rabeeh, hello, have you got my mail about RetroArch?
14:53 rabeeh kivutar: yeah !
14:54 rabeeh i'll send you an email about that
14:54 kivutar ok nice :)
15:58 Z0l hello
16:00 Z0l i added the details of the hdmi kernel panic into this forum post: http://www.solid-run.com/community/topic1456.html
16:01 Z0l in case anybody can help to troubleshoot, please ping me
16:37 kgp rabeeh: Where is the git repo?
16:37 kgp :)
17:06 rabeeh kgp: http://pastebin.com/N1tLe67V
17:06 rabeeh preview
17:06 rabeeh !!
17:06 rabeeh from that point you can 'apt-get install lxde lightdm'
17:07 cbxbiker61 hey rabeeh, i just got a notice that the hummingboard was shipped, thanks for that
17:08 rabeeh cbxbiker61: np
17:09 rabeeh kgp: the script uses xbian repos
17:49 Z0l rabeeh: any chance to continue our morning discussion? i rolled about 3 kernels so far with no luck
18:49 rabeeh Z0l: here
18:49 Z0l evening ;)
18:49 Z0l can you shed some light which kernel you want me to compile?
18:50 rabeeh if you are using geexbox; then you should be rebuilding geexbox all the way
18:50 rabeeh from scratch
18:50 rabeeh (for instance)
18:50 Z0l i've been trying to do that, but i couldn't find their source
18:50 Z0l they point to openbricks
18:51 Z0l but I'll look again and maybe ask them on their channel
18:51 Z0l I just thought you have a specific kernel in mind that includes HDMI patches
18:52 rabeeh oh no
18:52 rabeeh i was referring that you need to get a full distro built from scratch
18:52 rabeeh and then remove the cpuidle from it (via kernel configuration)
18:53 Z0l I can try that, but giving that kernel option worked as well
18:53 Z0l I mean I've seen it in the dmesg that cpuidle was turned off
18:53 Z0l also, I've made some progress and managed to have some kernel panics
18:54 Z0l not just oopses
18:54 Z0l you can see them here: http://www.solid-run.com/community/topic1456.html
19:00 rabeeh oh; so it's not cpuidle related then
19:00 Z0l nope
19:00 Z0l i think it's something with the mxc framebuffer driver
19:00 rabeeh different TV is ok - right>?
19:00 Z0l couldn't check that :(
19:00 rabeeh in what means?
19:01 Z0l i only have 1 tv
19:02 Z0l do you suggest it may be hardware related? I'll see if I can arrange testing at my friend who has a different TV
19:02 Z0l to me, it seems like something hangs when trying to read the edid and the connected device information and that's what's causing the error

21:10 Z0l bye
21:17 KodiakF http://www.anandtech.com/show/7724/it-begins-amd-announces-its-first-arm-based-server-soc-64bit8core-opteron-a1100
21:17 KodiakF Both of those are for rebeeh
21:18 malte he is currently away:)
21:18 KodiakF for when he comes back :)
21:19 KodiakF I have fingers crossed for a future that includes Solid-Run, RedHat Enterprise Linux, and AMD be it on ARM or x86_64, so it's cool to see AMD jumping on board
23:13 cbxbiker61 KodiakF, yep, i've been hinting to Rabeeh to go AMD if he can
23:15 cbxbiker61 I don't know how they'd do it, but it sure sound like AMD is going to be doing pin-compatible arm and x86
23:18 cbxbiker61 and the good thing is that AMD is back in profitibility with technology that looks good for the future, so I don't think they're going to disappear anytime soon
23:55 jmontleon where can i download the source for fsl-gpu-viv-mx6q? or at least get it from solid-run/freescale?
