jlrmagnusPi software. EMS and Emerald.00:03
jlrmagnusMostly00:03
jlrmagnusWhen I map cars (for a club), I use whatever comes my way.00:03
dbkaplunHow did you get into it? What did you read/learn? What was your first change?00:04
jlrmagnusI built a Caterham 7 with a stock Ford engine. At some point I got a Pectel T6 ECU, had it wired into my existing sensors, and started mapping.00:05
jlrmagnusI think I started playing with idle, which is pretty risk free.00:05
dbkaplunjlrmagnus: were you studying from anything or just playing with numbers randomly?00:09
jlrmagnusI had a book. One sec.00:09
jlrmagnushttp://www.amazon.com/Modern-Engine-Tuning-Graham-Bell/dp/185960866300:10
jlrmagnusAlthough I didn't use it that much.00:10
jlrmagnusChange one thing at the time, and make sure you understand the consequences of what you did before you change the next thing.00:12
jlrmagnusGet a wideband lambda probe / O2 sensor.00:12
jlrmagnusBe prepared to rent a dyno if you want to get a good map.00:12

jlrmagnusIf you know ignition is good, leave it alone and focus on fuel injection.00:13
jlrmagnusTry to get a lambda value of ~0.95-0.97 for a naturally aspirated engine.00:14
jlrmagnus(13.97  -  14.26 for AFR)00:15
jlrmagnusOnce you have a base map in place, do tip in (also called transient) fueling to ensure that you have a solid engine response when you apply throttle everywhere in the map.00:16
jlrmagnusGotta go. Back tomorrow at 8:30 PST /  16:30 GMT.00:24

fredcadetegood morning07:00
fredcadeteWalt just sent a very good GENIVI/AGL/Tizen gap analysis to the agl-discussions list07:01
fredcadetehttp://lists.linuxfoundation.org/pipermail/automotive-discussions/2015-October/000914.html07:01
fredcadeteit's mandatory reading07:01
*** tcouniha has joined #automotive07:01
*** gmacario has joined #automotive07:04
*** KlausUhl has joined #automotive07:04
fredcadeteTarnyko: that gap analysis recommends dleyna as a DLNA server07:07
fredcadeteit was probably written before the proposal of Rygel07:07
fredcadeteit was probably written before the proposal of Rygel\07:12
fredcadetestupid window focus07:12
Tarnykofredcadete: hi ; yes we've worked hard on these docs07:13
fredcadeteTarnyko: oh, right. You're in iot.bzh07:14
fredcadeteI was forgetting07:14
Tarnykoyes :) Tizen IVI had Rygel and DLNA at the same time, in my understanding they were playing together to give the whole functionality07:14
Tarnyko*Dleyna07:15
fredcadeteah07:15
fredcadeteok then07:15
fredcadeteabout libav: just to make sure, you are aware of the libav/ffmpeg switch?07:16
fredcadetehttp://lists.openembedded.org/pipermail/openembedded-devel/2015-July/102207.html07:16
*** pratikdesai_ has quit IRC07:16
*** pratikdesai has joined #automotive07:17
JEEBffmpeg/libav is a mess. it seems like vlc is switching between them with windows binaries and both are broken in diff ways07:19
*** pratikdesai has quit IRC07:19
*** pratikdesai has joined #automotive07:20
TarnykoRygel, additionally to UPnP discovery and HTTP streaming, is also a DLNA server. But although it provides a DLNA client API (http://www.murrayc.com/permalink/2012/06/22/rygel-for-a-dlna-player/), it is not a full-fledged DLNA client/AV controller07:20
TarnykoI think this is worth reading : http://elinux.org/images/1/13/Rygel_Open_Source_DLNA.pdf (short story : Rygel and Dleyna are playing together, the latter acting more as a frontend)07:21
JEEBffmpeg has more features and various hacks, libav is more towards required review and internal improvements which then get merged into ffmpeg07:21
fredcadeteJEEB: the recent switch back to ffmpeg on debian is mostly motivated by responsiveness to security flaws07:23
fredcadetelwn says it all: https://lwn.net/Articles/650816/07:23
JEEBthat discussion was a mess too. I'm related to both projects :p but yes, I've been using ffmpeg myself for quite some time in production07:24
fredcadeteyou'll certainly know better than me then07:26
*** pratikdesai has quit IRC07:29
*** tcouniha has quit IRC07:33
TarnykoJEEB, fredcadete: I feel like these discussions always end up on an irrational "project vs project" fight07:48
*** tcouniha has joined #automotive07:49
*** pratikdesai has joined #automotive07:50
*** persia has quit IRC07:50
*** persia has joined #automotive07:51
fredcadeteI agree07:52
JEEByeah07:52
fredcadeteI raised the issue to make sure that AGL is aware of this07:52
fredcadeteand doesn't say "libav" too strongly07:52
fredcadetethe sane thing would probably to use whatever libav/ffmpeg the target version of Yocto is supporting07:53
fredcadeteand leave the choice to Yocto07:53
Tarnykogood point07:53
JEEByeah07:53
fredcadetefor now it's still libav, so keep libav07:53
*** pratikdesai has quit IRC07:53
JEEBanyways, if one good thing came out of the fork, it's that both ffmpeg-new and libav are better than ffmpeg-old circa 2010. the fact that we still have two upstreams is unfortunate, though07:54
Tarnykoideally the switch would even be painless because libav/ffmpeg intend(ed?) to be API-compatible.  I agree that we shouldn't mention a specific project as a final target07:54
*** pratikdesai has joined #automotive07:54
JEEByes, the only exception is that FFmpeg makes you do --enable-avresample to enable it. otherwise API-wise in general similar version are compatible07:54
JEEBnot ABI-compatible although some people at some point thought of that, too (there might even be an option for it which is largely untested and seems to crash and burn)07:55
*** kooltux has quit IRC07:55

Tarnykogood to know for the "--enable-avresample" thing... yes I remember trying to replace one with the other at runtime, and that it didn't go too well :)07:58

waltminer=== AGL Dev Meeting ===12:02
paulsherwoodhi12:03
kooltuxhi all12:04
waltminerReviewed action items from last meeting.12:06
*** jbocklage has joined #automotive12:06
waltminerTanikawa has created a minimal SDK with Qt5 and Qt Creator available12:07
waltminerSDK checked on porter board. Should be easy to create for QEMU as well12:09
waltminerCurrently there are two SDK versions. The “Full Version” has Qt5 included12:14
waltminerCurrently a full build us required by the developer to run the SDK12:14
waltminerNeed to figure out a way to deliver pre-built binaries for the SDK12:15
*** mdurnev has quit IRC12:15
waltminerPoky produces a shell script for installing the build. Should be easy to modify to install binary12:15
waltminerWalt will ask Jan-Simon about re-using the binary from Jenkins to deliver the SDK12:18
*** pratikdesai has joined #automotive12:18

kooltuxtrying to unmute on gotomeeting...12:20

kooltuxstrngely, I'm not nmuted...12:21
kooltuxanyway go on :)12:21
kooltuxmy mic is shared through firefox... maybe this is a bug :\12:21
*** pratikdesai has quit IRC12:22
kooltuxyep on linux12:22
kooltuxmy mic is working correctly but the sahring is probably failing12:22
kooltuxI'm going to call through phone12:22
*** jeremiah has joined #automotive12:26
*** samuli has joined #automotive12:29
*** riazantsev has joined #automotive12:30
paulsherwoodFulup: would you mind changing the topic back? this is not only a channel for agl12:39
kooltuxagain lost the line this time !12:40
kooltuxnot my day12:40
jeremiaho_O12:41
paulsherwoodit would be best if folks documented the call here. i can't today sadly, am busy elsewhere12:41
waltminerSnapshots/versioning on AGL: what's the mechanism to open a bug on jira and reference a given "snapshot"  Example: when systemd has been added to meta-agl, this broke network (DHCP) and corrupted the splash screen. What's the official mechanism to reference a snapshot ?12:42
waltminerAction item: Walt will work with Stephane and Jan-Simon to propose a mechanism for snapshot references that can be created by Jenkins and referred to in Jira.12:42
waltminerStephane: Security layer integration: we are ready to push our work on security, which depends on meta-intel-iot-security. For this, creating a new subdir meta-agl/meta-agl-security would make sense.12:43
waltminerTanikawa asked if the security layer is mandatory or adoptive  as this would affect the structure of the repo12:49
jbocklage+1 for recipes-security in meta-agl layer12:53
waltminerQuestion about whether to add recipes-security to meta-agl or add a meta-security layer to AGL12:53
kooltuxtrying meta-agl/meta-agl-security first would be the best IMO12:55
jobol+1  meta-agl/meta-agl-security12:55
kooltuxjbocklage, if we use recipes-security, we won't see clearly which "other" components in recipes-* are impacted12:55
kooltuxwuth meta-agl/meta-agl-security, we'll add recipes-* as in meta-agl12:56
jbocklageso in  meta-agl/meta-agl-security we would have a kind of a copy (maybe a subset) of the meta-agl/recipes-* folder structure, but populated with .bbappend-files to add security to the original packages?12:58
*** tom__ has joined #automotive12:59
jeremiahI think it should be named a little more clearly, i.e. meta-agl-smack or whatever since not everyone is going to use the specific MAC solution12:59
kooltuxjbocklage, yep12:59
jbocklageok. makes sense. then you can have my "+1". (had a different understanding before)13:00
joboljeremiah, or features it inside meta-agl-security13:00
jeremiahjobol: Also an option, but what else is there in meta-agl-security?13:00
jeremiahAnd will there be different layers in the future?13:00
*** CTtpollard has quit IRC13:02
jeremiahwaltminer: Your cursor is still blinking in Gotomeeting13:07
jeremiah:-)13:07
jeremiahBut I guess the meeting isn't over?13:07
*** tom__ is now known as CTtpollard13:12
waltminerAgreed that we will start with meta-agl-security or (-smack)13:13
waltminerStephane:emo 2016: we work for a demo of the project "Full Prototype IVI System"13:13
waltminer(https://wiki.automotivelinux.org/project-proto-ivi-system) to be shown at CES13:13
waltminer2016. Where does this work could be pushed:13:14
waltminer  - meta-agl-demo main branch, if reviews are fast enough ?13:14
waltminer  - meta-agl-demo in new specific branch 'demo2016' with push rights to bypass13:14
waltminerreviews if not enough reviewers and/or reactivity ?13:14
waltminer  - a new meta-agl-demo2016 ?13:14
waltminerTanikawa: structure for building demo apps has not been determined13:14

*** jbocklage has quit IRC13:20
*** jbocklage has joined #automotive13:21
*** pratikdesai has quit IRC13:23
jbocklagethx!13:24
waltminerDecided to start with the existinhg structure AGL/DemoApps/appname. Can open up the permissions within the project easily enough13:25
waltminerStephane will let Walt know what to name the app and it will be created in gerrit13:25
waltminer=== End AGL Meeting ===13:25

c0dd3r5and editing the "transform=" in /etc/xdg/weston/weston-user.ini doesn't make a difference13:32
c0dd3r5(even though I am able to change, for example, the background colour successfully, so I know the file is being read)13:33
c0dd3r5any thoughs?13:33

c0dd3r5huh. found it13:35
c0dd3r5it was in /tmp/genivi-weston.log13:35
c0dd3r5because AGL reference platform?13:35
c0dd3r5but I have a stanza for HDMI3, and it still doesn't change anything13:36

*** fredcadete has joined #automotive13:43
c0dd3r5okay. no. got it13:43
c0dd3r5so the file in /run/user/5000/weston.log is a red herring13:43
c0dd3r5the log in /tmp/genivi-weston.log is the good one13:43
c0dd3r5and is reading /etc/xdg/weston/weston-genivi.ini13:44
