CTtpollardleon-anavi: we've just tweaked something in the qemu-ci pipeline, I've started it again but I feel confident about merging your patches either way today11:38
leon-anaviCTtpollard, ok, thanks for the feedback.11:40
leon-anavibtw I spent some time working on GDP for rpi2. I built it using master branch of meta-raspberrypi but Weston fails to start.11:41
CTtpollardyeh I saw your update on the jira ticket, I'm building it my self personally11:41
leon-anaviyes, I posted details in jira GDP-8211:41
CTtpollardand the sneaky raspi3 dtb11:42
* gunnarx is picking up his Pi 3 from the post office today :)11:45
CTtpollardgunnarx: nice!11:50
gunnarxNot promising I'll have a lot of time for testing, but it's a start11:51
gunnarxor maybe it just ends up being a media player in my car, who knows11:52
leon-anavigunnarx, nice :)11:57
leon-anaviI got my rpi3 last week but yesterday I found time to boot it with Raspbian for the first time :)11:58
*** fredcadete has quit IRC11:58
rjekI need to buy a new uSD card and pop it in mine11:58
rjekI also bought some heat sinks; I've seen scary IR photography of Pi311:59
CTtpollardrjek: metal or potato?12:00
CTtpollardchbae: do you want to push your patches to feature/dev branches, for instance changhyeokbae/raspberrypi2 in meta-genivi-demo and genivi-demo-platform? You should have the rights to do this now12:01
rjekCTtpollard: Metal heatsinks, pototo uSD12:01
*** gunnarx has quit IRC12:09
CTtpollardchbae: I've updated the jira ticket here https://at.projects.genivi.org/jira/browse/GDP-8112:19
*** fredcadete has joined #automotive12:57
fredcadetehello folks13:01
fredcadeteany suggestion on how to stress the cpu of a poky distribution from the command line?13:01
waltminerIs the Stephen Lawrence on IRC?13:03
paulsherwoodnot at this time13:28
rjekbzip2 < /dev/urandom > /dev/null13:28
paulsherwoodfredcadete: ^^13:28
rjekRun one for each CPU core13:28
rjekThat'll thrash CPU and cache and RAM13:28

rjekIt's my best side.13:29

fredcadeteI have just very rudely ignored your efforts and used stress-ng13:50
paulsherwoodheh13:50
* paulsherwood goes to sulk in another channel13:50
fredcadetebut that bzip and urandom wins the creativity award :)13:50

*** chbae_ has joined #automotive13:53
chbae_Hi.14:00
chbae_CTtpollard: I just see now.14:00
CTtpollardhey :)14:03
chbae_CTtpollard: Did you test my patchset?14:29
CTtpollardchbae_: I'm building it, but like I say having your own pre merge branches is probably a good idea14:29
chbae_CTtpollard: I’ll. then how about the layering discussion yesterday?14:29
chbae_CTtpollard: According to the discussion, my patchset can be different.14:31
*** sanjeev has joined #automotive14:32
*** gunnarx has quit IRC14:36
CTtpollardchbae_: I'm fine with the layering, I was just suggesting other options14:37
*** gmacario has joined #automotive14:38
chbae_CTtpollard: ok. thx. another question is that Can I create my dev branch from master or qemux86-64 branch?14:38
CTtpollardwell there is no 'master' branch in genivi-demo-platform, so on top of the qemux86-64 is what we use as a 'base' branch, and add the bsp layers etc14:41
*** gmacario has quit IRC14:43
chbae_CTtpollard: Ok. that’s good. Then I suggest about genivi-demo-platform.14:43
chbae_CTtpollard: What don’t you set the qemux86-64 branch as default branch in genivi-demo-platform.14:43
chbae_CTtpollard: When I use “git clone …./genivi-demo-platform”, I got the below warning because default branch isn’t set.14:44
chbae_CTtpollard: warning: remote HEAD refers to nonexistent ref, unable to checkout.14:44
CTtpollardchbae_: I've requested the remote head to be set as that branch before, but it needs git shell access on the gitolite server which I don't have the powers to do14:44
chbae_CTtpollard: Ah. I’ll suggest it to mailing list.14:45
CTtpollardhttp://stackoverflow.com/questions/13949093/git-change-default-branch-gitolite14:46
chbae_CTtpollard: Yes. we need to request it to gitolite manager.14:47
CTtpollardlike I say it has been requested, at the time I think jeremiah|AFK tried to take it further, the git server is handled by LF afaik14:48
CTtpollardmaybe it should be put into the tools team JIRA14:49
CTtpollardor GDP jira14:49
* paulsherwood wonders what's the benefit of maintaining these parallel branches14:50
chbae_CTtpollard: So I’ll send it to mailing list. :)14:50
chbae_Hi paulsherwood14:51
chbae_sent14:52
CTtpollardpaulsherwood: it's a topic that I hope to discuss at the AMM14:52
chbae_paulsherwood: what is meaning of these parallel branhes?14:52
*** gmacario has joined #automotive14:52
*** phongtran has joined #automotive14:53
CTtpollardchbae_: I believe he means having a single branch of gdp, capable of building all targets14:56
chbae_CTtpollard: including genivi-demo-platform repo?14:57
CTtpollardchbae_: yes, so instead of having a branch per target, having a single branch that can build all targets14:58
chbae_CTtpollard: I agree about meta-genivi-demo repo but genivi-demo-platform branch may be difficult in my opinion.14:59
CTtpollardwell for meta-genivi-demo we try to use the same commit for all targets, hence why your restructuring work is helpful for that14:59
chbae_CTtpollard: Yes. :)15:00
CTtpollardI think it'd be possible for genivi-demo-platform, but would require some tweaking and additions15:00
*** gmacario has quit IRC15:00
*** mvick has joined #automotive15:00
chbae_CTtpollard: yes.  ex) MACHINE, meta-layers, and so on...15:01
CTtpollardyeh, I think some PoC that uses scripts to generate all the confs etc could handle it, maybe expanding on the init.sh for user interaction15:02
chbae_CTtpollard: Ah yes. that’s good idea.15:04
chbae_CTtpollard: we can refer https://github.com/openwebos/build-webos.15:05
chbae_CTtpollard: it uses mcf scripts and weboslayers.py configuration file.15:06
chbae_CTtpollard: It’s good example for it.15:06
*** chbae has quit IRC15:10
*** chbae_ is now known as chbae15:10
CTtpollardcool15:10
chbaeCTtpollard: ex) ./mcf raspberrypi, then meta-raspberrypi layer is coming. or ./mcf silk, then meta-renesas layer is coming.15:12
CTtpollardyeh it's a nice idea, I don't think it has to be overly advanced to start off with15:13
* paulsherwood usually starts by trying the simplest step that might possibly work15:15
chbaepaulsherwood: Sure.15:15
chbaepaulsherwood: Now I fully agree your opinion about using signle branch. :)15:16
chbaeCTtpollard, paulsherwood: it’s not difficult and I can create the script to use single branch with low priority.15:19
chbaefor test.15:19
CTtpollardchbae: once your raspi branches are in the repos, we can start a pipeline on the go server, as an extra pre merge check15:22
chbaeCTtpollard: sure. I’ll do it now :)15:22
fredcadetechbae: btw I am having a look at the parallel build issue with wayland-ivi-extension15:25
fredcadeteto see if we can avoid setting PARALLEL_MAKE=""15:25
chbaefredcadete: if it’s possible, it’s greate.15:25
chbaeCTtpollard: I created chbae/raspberrypi2 branch and submit my patches.15:48
CTtpollard:D http://git.projects.genivi.org/?p=genivi-demo-platform.git;a=shortlog;h=refs/heads/chbae/raspberrypi215:50
chbaeCTtpollard: yes.15:50
chbaeCTtpollard: Actually I’ll work in my github and to create go.cd pipeline, I’ll forcely update my chbae/raspberrypi branch :)15:53
*** sanjeev has quit IRC15:54
chbaechbae: CTtpollard: personally I’m fimiliar with jenkins and I’m using jenkins for local test and CI to manage patches.15:55
CTtpollardchbae: yeh it's fine to force push there, it's a dev branch so users must expect it to be in a state of flux15:56
chbaeCTtpollard: yes.15:57
chbaeCTtpollard: Can I add my maintainership in MAINTAINER file like15:57
chbaeM:      Changhyeok Bae <changhyeok.bae@gmail.com>15:57
