jeremiahHello earthlings and assorted aliens!12:24
CTtpollard:)12:24
leon-anaviI booted GDP on rpi2 using branch jethro of meta-raspberrypi and the github fork of meta-genivi-demo. Weston was started but the screen stuck on GENIVI logo.12:24
jeremiahCTtpollard: Just the humanoid I was hoping to speak to. :D12:25
leon-anaviObviously there are some patches in master branch of meta-raspberrypi which prevent Weston from running on rpi2 with GDP.12:25
jeremiahCTtpollard: I wonder about the extent of the Android Auto integration into the GDP12:25
jeremiahI've seen the git repo in GENIVI's gits that shows work on layers has been done12:25
jeremiahBut I wonder if that has been brought into the GDP "officially"?12:26
CTtpollardjeremiah: yeh Maxim submitted this branch http://git.projects.genivi.org/?p=genivi-demo-platform.git;a=shortlog;h=refs/heads/koelsch-aa I can't personally test it without the AA libs from google12:26
jeremiahCTtpollard: Right, of course, that would be a blocker not having the Google blobs.12:26
jeremiahOkay then, now I know where we are and I'll mention that in the OSS meeting I have to drop into now. :-) Thanks!12:27

CTtpollardleon-anavi: looks like the pipeline is having issues with some parallel make in qtmultimedia15:41
CTtpollardwhich is really annoying because I can't reproduce it!15:41
leon-anaviCTtpollard, is it some kind of a race condition? May be some dependencies are not built on time.15:42
leon-anaviCould you please share the log of the fail?15:43
CTtpollardwe're using qt5.4.2 and it looks like it should have been fixed there15:43
CTtpollardit has been reported here http://www.qtcentre.org/threads/63713-Random-QtMultmedia-build-issues-with-QtWebkit5-parallel-builds15:43
leon-anaviCTtpollard, what are the configurations for PARALLEL_MAKE and BB_NUMBER_THREADS when the build is failing?15:44
CTtpollardthe pipine line conf is set to 2 and j215:45
leon-anaviok, I expected more :)15:48
leon-anavianyway it is strange that it cannot be reproduced.15:48
CTtpollardlooks like there was a patch proposed to it but not merged https://codereview.qt-project.org/#/c/112214/115:50
CTtpollardchecking in the work dir, it's definitely qtmultimedia 5.4.215:50
CTtpollardI could lower the parallel make value, but would rather not globally15:54
CTtpollardbut.... other pipelines are not having the same issue, with the same recipe15:55
* CTtpollard sighs at friday 15:55
leon-anaviI didn't notice any errors while testing the build. I used 8/j8 and 12/j12 on my dev machines.15:56
CTtpollardI'm using 4 myself locally, and I don't see the issue :)15:57
leon-anaviCTtpollard, I have a success story to share :) GDP on Raspberry Pi 315:57
CTtpollardleon-anavi: that's awesome!15:59
*** waltminer has joined #automotive16:00
rjekIn 32 or 64 bit mode? :)16:01
JEEB64bit is kind of still meh on the rpi3 at this point, no?16:02
JEEBas in, requires kernel work16:02
rjekI thought there was a kernel already, but Raspbian han't rebuilt all the things for ARMv8 yet because it's a lot of faff and storage16:03
leon-anavidon't get too excited :) I have just booted it. Weston is running.16:04
JEEBI wonder mpv would work with the rpi opengl stuff under wayland (weston)16:04
leon-anaviI see GENIVI background and that's all. I expected to see a few apps. Wondering whether this is what I should see.16:04
leon-anavirjek, Linux raspberrypi3 4.1.0 #1 SMP PREEMPT Fri Mar 18 17:33:25 EET 2016 armv7l GNU/Linux16:05
JEEBrjek: last I saw it was still heavily in-progress and the rpi foundation is content with armv7 binaries for the rpi3 all-over16:05
leon-anavihttps://twitter.com/leonanavi/status/71085906216293171216:06
*** philrob has quit IRC16:07
rjekHmm, the RPi3 very much is not ARMv716:07
rjekIt is ARMv8; not all ARMv7 code can run on it16:08
JEEBaye16:10
leon-anaviyes, sure it is ARMv816:12
leon-anavibut there some difficulties with meta-raspberrypi :)16:14
leon-anaviRaspberry Pi 3 configuration are in branch master. The current efforts for porting GDP to rpi2 are based on branch jethro.16:15
leon-anaviSwitching to branch master leads to issues with Weston due to new patches for it and userland. These patches have been applied recently only in the master branch of meta-raspberrypi16:16
rjekI think the only incompatibility anybody will ever likely notice is that ARMv8 lacks the SWP instruction, regardless of which length mode you run it in16:16
leon-anaviso what I did was to use an older commit from branch master of meta-raspberrypi. Furthermore the image is with Linux kernel 4.1.16:17
leon-anavilong story short there is plenty of work on this :) I just had a few spare cycles and decided to give it a try.16:17
leon-anaviI will post details in JIRA and I will switch back to tasks with higher priority.16:18

gunnarxEveryone, just pretend I tweeted the same pictures as leon-anavi17:08
gunnarxExcept the booting :)17:09
gunnarxso I don't have to :)17:09
CTtpollardI can be bribed17:10
CTtpollardgunnarx: I thought you planned to use it as a media player in your car? :P17:13
rjekIf it can play BBC Radio 4 at me, it is a feature complete entertainment system17:14
gunnarxyah we'll see.  If it's doing audio only it's kind of overkill as Pi 1 should suffice.  But the Pi3 has nice wireless interfaces.17:15
CTtpollardand 3 is the magic number of course17:15
rjekThe analogue output on the Pi is execrable.17:16
rjek(It uses one of the SoC's PWMs and a capacitor)17:16
*** _jlrmagnus has joined #automotive17:16
rjekWell two of each because it's stereo17:16
gunnarxoh17:17
gunnarxthat I do not want17:17
rjekThere are a handful of decent audio output "hats" for the Pi though that use the I2S on the expansion header17:18
gunnarxI think I have a decent USB "audio card", guess that's a way to go.17:18
* gunnarx looks up execrable17:19
CTtpollardout of shields, hats and capes I think hats is my favourite17:19
rjekOr even the cheapest USB audio device you can find; it'll be better than the built-in analogue17:19
rjekCTtpollard: What about IO Wimple?17:19
gunnarxdeserving to be execrated.  yeah it sounds pretty terrible17:20
rjekhttps://www.google.co.uk/search?q=define+execrable17:20
CTtpollardgunnarx: get used to words like that from rjek17:20
gunnarxCTtpollard, no, radiation shields. They're the best.17:20
*** Sisco_ has quit IRC17:21
rjekWhat's wrong with execrable?  It's a totally cromulent word.17:21
*** Sisco has joined #automotive17:22
gunnarxit obnubilates the actual meaning17:22
gunnarxthat's what's wrong with it17:23
rjekobfuscation was not my intention17:24
rjekBut "execrable" is a stronger word that "bad"17:25
rjekBut it is many more letters, I admit17:25
