| gunnarx | Hi RzR | 09:15 |
| gunnarx | how have you been. and what are you working on? :) | 09:15 |
| RzR | I've played a bit w/ MCU recently | 09:18 |
| RzR | and about to update meta-oic | 09:19 |
| RzR | If you want to build iotivity in images, ping me :) | 09:19 |
| gunnarx | microcontrollers? | 09:20 |
| RzR | yea arduinos | 09:20 |
| gunnarx | Marvell cinematic universe? :) | 09:20 |
| RzR | http://www.slideshare.net/SamsungOSG/iot-from-arduino-microcontrollers-to-tizen-products-using-iotivity | 09:20 |
| gunnarx | ok :) | 09:20 |
| RzR | GENIVI is mentionned ^ | 09:20 |
| gunnarx | naturally | 09:21 |
| gunnarx | cars are hot | 09:21 |
| gunnarx | oh, the "standards" xkcd :) | 09:21 |
| gunnarx | we have it on our wall next to the coffee machine | 09:21 |
| gunnarx | instead of images, I'd rather (continue with) getting iotivity clients into GDP | 09:23 |
| RzR | I suppose it's one w/ "capsules" or maybe it translates | 09:23 |
| RzR | gunnarx, the basic clients I proposed where rejected, maybe the bug could be reopen | 09:24 |
| gunnarx | yeah maybe | 09:24 |
| *** ronan__ has quit IRC | 09:24 | |
| gunnarx | It's about variation, we have discussed a lot about that lately. What goes into GDP master should be "for everyone" but that's a tricky balance | 09:25 |
| gunnarx | we encourage variants and experiments for sure. I think last time the discussion was about how easy it is for people to use it, what additional hardware they need, what needs to be available on server side etc. | 09:26 |
| gunnarx | downloaded your slide deck for tablet viewing now :) | 09:27 |
| RzR | one question is RPI port stable ? | 09:31 |
| gunnarx | AFAIK, as good as any. CTtpollard - comment? | 09:32 |
| *** JordonWu has quit IRC | 09:32 | |
| fury | hi guys | 09:33 |
| fury | how's it hangin? | 09:33 |
| gunnarx | RzR: I know it was the preferred target for one out of two hands-on sessions | 09:34 |
| gunnarx | and also the first target build for the new RC3, so yes I have not heard of any problems. | 09:34 |
| RzR | I will give a try on pizero | 09:34 |
| RzR | don't hold your breath :) | 09:34 |
| gunnarx | no :) | 09:35 |
| gunnarx | I assume you build from source and in that case you can do Minnowboard or whatever you like, but if you don't build from source you want the RPi-RC3 image | 09:35 |
| gunnarx | wiki -> GDP -> GDP downloads | 09:36 |
| RzR | yes BFS I am not cheating :) | 09:36 |
| gunnarx | Have you tried the SDE? | 09:36 |
| *** leon-anavi has quit IRC | 09:36 | |
| gunnarx | would be cool to get your impression and feedback for improvement | 09:36 |
| RzR | what is that ? | 09:36 |
| RzR | ide ? | 09:37 |
| gunnarx | pretty much | 09:37 |
| RzR | eclipse ? | 09:37 |
| gunnarx | wiki -> GDP -> GDP SDE read and download :) | 09:37 |
| gunnarx | eclipse part could do with some testing and feedback, most users are on qt creator I think | 09:38 |
| RzR | nice qtc | 09:38 |
| *** leon-anavi has joined #automotive | 09:45 | |
| *** john3voltas has joined #automotive | 09:48 | |
| CTtpollard | Master 'RC3' works on all supported GDP boards, just not 'officially' | 09:55 |

| gunnarx | leon-anavi, did you try Webex on Linux yet? | 12:29 |
| * radiofree wonders if anyone has ever successfully managed that | 12:31 | |
| gunnarx | radiofree: I run it all the time, and it's documented: https://at.projects.genivi.org/wiki/display/TOOL/WebEx+on+Linux | 12:33 |
| gunnarx | I had an idea for this weekend to package that into a VM, something with no fuss and no need to taint your system | 12:34 |
| radiofree | gunnarx: flatpak container please :D | 12:35 |
| gunnarx | heh | 12:35 |
| gunnarx | that'll be generation 2 | 12:35 |
| gunnarx | vagrant is too easy | 12:35 |
| fury | I got as far as compiling a usb driver kernel module, but it can't load it because all the usb symbols are unknown :D | 12:35 |
| gunnarx | Just checking with leon, just in case | 12:36 |
| radiofree | fury: when you insmod? | 12:36 |
| fury | yup | 12:36 |
| radiofree | use modprobe | 12:36 |
| radiofree | that'll load the dependencies | 12:36 |
| fury | where do i need to put the module for modprobe to work? | 12:36 |
| radiofree | i guess i've never got webex working because i din't know about the 32-bit lib requirement | 12:36 |
| fury | cause i compiled it in a different dir | 12:36 |
| radiofree | it should still have a make modules_install | 12:36 |
| radiofree | INSTALL_MOD_PATH=/tmp/foo | 12:37 |
| radiofree | then install it to target and run depmod | 12:37 |
| radiofree | failing that, modprobe some usb related module and hope that's good enough to insmod with | 12:37 |
| fury | that was how i compiled the kernel and the modules that came with it, but this one is a new one i'm writing, it isn't part of the kernel build yet (is that easy to do? like, add my little driver thingie in as one of the selectable menu options in the menu config) | 12:39 |
| fury | i was following some tutorial on the youtubes about writing a kernel module usb driver and he compiled it in a separate dir, just included the Linux headers, his seemed to work but i'm also cross compiling...maybe i shouldn't try to cross compile, but didn't feel like waiting a few hours for a kernel build on an imx6 | 12:43 |
| radiofree | well if you're getting symbol errors it sounds like you're using something from another module that hasn't been loaded yet | 12:44 |
| radiofree | what symbols is it complaining about? | 12:44 |
| fury | basically usb_*... usb_alloc_urb, usb_autopm_put_interface, usb_free_urb, usb_alloc_coherent, several others... | 12:45 |
| radiofree | check /lib/modules/$VERSION/kernel/drivers/usb | 12:46 |
| radiofree | if you have something like usb-storage (in storage) do `modprobe usb-storage` and that should bring in a lot of the usb subsystem | 12:46 |
| radiofree | then try and insmod yournewmodule.ko | 12:46 |

| fury | hmm. only thing i found in there that i could load was an ftdi_sio thing, and that didn't seem to do the trick | 12:59 |
| fury | maybe i started from the wrong base with the usb skeleton? | 13:00 |
| radiofree | well... does usb work on that target? :) | 13:03 |
| fury | yup, I've got a usb mouse and keyboard hooked up. i think most stuff is hardwired into the kernel, though, not as loadable modules | 13:04 |
| fury | lsmod only lists a few tihngs | 13:04 |
| radiofree | interestingly you should get usb_free_urb etc.. from core (CONFIG_USB) | 13:05 |
| * radiofree doesn't know what it's not working then | 13:08 | |
| radiofree | do you have your config in /proc/config.gz? | 13:08 |
| fury | yup | 13:09 |
| fury | CONFIG_USB=y | 13:10 |
| radiofree | do the symbols show up in /proc/kallsyms? | 13:14 |
| radiofree | e.g cat /proc/kallsyms | grep usb_free_urb | 13:14 |
| *** tylercampbell has joined #automotive | 13:18 | |
| *** kooltux_ has quit IRC | 13:24 | |
| fury | yup | 13:53 |
| leon-anavi | hi gunnarx no, I haven't tried it yet. My plan is to try it next Wed before the meeting. | 14:18 |
| leon-anavi | I have bookmarked the article :) | 14:18 |
| gunnarx | np, as you can see I might try creating a Vbox for it - I wouldn't mind having that setup for myself. | 14:19 |
| CTtpollard | at that point isn't it easier to just have a windows vm? | 14:20 |
| radiofree | no | 14:22 |
| CTtpollard | well easier to not use webex all together, but that's a different argument | 14:22 |
| toscalix | the new version of the Android Webex client allows now the Share screen option, so I would go for that one | 14:23 |
| CTtpollard | or, use arc welder in chrome to run the android app under linux | 14:24 |
| CTtpollard | for even more fun | 14:24 |
| *** AlisonChaiken has quit IRC | 14:45 | |
| fury | i got one of those RTL dongles, how do I make the radio screen do thing? | 14:47 |
| fury | it says TypeError: Property 'play' of object Radio_QMLTYPE_90(0x1204a8) is not a function | 14:48 |
| fury | IMAGE_INSTALL_append = " rtl-sdr" I guess? | 15:01 |

| fury | thinking seriously about some massive cores...perhaps a 10-20 core server for building AGL or something. I'm already tired of waiting hours for a build :P | 16:34 |
| *** jlrmagnus has quit IRC | 16:36 | |
| leon-anavi | AGL has a Jenkins server which is building images quite often | 16:36 |
| leon-anavi | I believe that each patch submitted in Gerrit triggers a build in Jenkins | 16:36 |
| fury | Thinking along the same lines, of having a Jenkins server in house. what kinda hardware is that one running? | 16:37 |
| *** caiortp has joined #automotive | 16:40 | |

| fury | yup | 18:12 |
| fury | should the fm radio app work out of the box or do I need to config something? | 18:13 |
| fury | I get an error that "play" is not a function | 18:14 |

| smurray | fury: fixing it is kind of mdp and myself's plate, but feel free to dig in ;) | 18:17 |
| smurray | err, on our plate | 18:17 |
| mdp | still dealing with h/w dependent rpi3 issues | 18:19 |
| fury | oh, ok :D I didn't know it wasn't working, my bad. I dunno much about this stuff yet, I saw it was on the wiki for the ALS2016 demo apps and figured if I got that dongle and plugged it in I could hear some radio stations | 18:19 |
| fury | I'm still trying to figure out how to get set up to submit patches for the couple things I've run into | 18:20 |
| fury | and fumbling my way through kernel USB driver module development | 18:20 |
| smurray | fury: the radio stations are hard-coded, at the very minimum, you'll need to edit FMRadio.qml to change them | 18:23 |
| fury | ah. that I can do, I hard coded songs for the media player | 18:23 |

| fury | hmm. I just hooked up the gechic 1502i to the porter, not getting any signal :o | 18:59 |

| fury | now I know why the radio was taken out of the demo for CES2016 :D | 20:48 |
| leon-anavi | :) | 20:49 |

| *** murphy has joined #automotive | 22:19 | |
| fury | 40 cores? | 22:19 |
| dl9pf | its a cloud, so ~10 machines if needed . each machine has 16gb ram + 8 core | 22:19 |
| fury | ah | 22:19 |
| fury | nice | 22:19 |
| fury | how do you spread across multiple machines, is that built into the cloud server stuff or is it something I can hackjob together with a gaggle of quad core machines? | 22:20 |
| fury | cause quad core machines I got out the wazoo, couple on this desk, couple on that desk... | 22:21 |
| dl9pf | jenkins has an openstack cloud plugin that spins up the minions . | 22:21 |
| dl9pf | you can mimic that with real hardware slaves . | 22:21 |
| fury | awesome | 22:21 |
| dl9pf | jenkins queries gerrit and triggers builds when changes come in. | 22:22 |
| fury | 4 quad core desktops is probably cheaper than 1 16-core | 22:22 |
