mvladtanmaytj: can you paste the contents of /run/platform/display/compositor.log?09:34
mvladtanmaytj: preferably, on pastebin09:34
mvladtanmaytj: I suspect that the container doesn't access to /dev/dri/card*. Could you also paste ls -al /dev/dri/*?09:35
tanmaytj@mvlad: Please find the logs here https://pastebin.com/X67H5M2f09:40
*** tanmaytj has quit IRC09:42
*** tanmaytj has joined #automotive09:43
tanmaytjmvlad: Also note that am able to launch weston directly from the container and run weston applications like weston-flower etc09:47

mvladtanmaytj: seems odd that the log file itself can't be found. Did you remove by any chance? Can you try running agl-compositor by hand, just like weston? Like ExecStart but w/o the log arg12:40
mvladtanmaytj: for weston did you use --drm-device? I see 4 card nodes under /dev/dri/.12:42
smurrayI'm curious what your container host is.  A lot of desktop distro kernels probably do not have SMACK support, and it's unclear to me what the lack of it will trigger12:49

mvladuhum, by the looks it looks like perm issue, tanmaytj ^^13:14
tanmaytjmvlad: agl-ccompositor run by hand from the docker shell works fine and it does log to /run/platform/display/compositor.log14:30
tanmaytjmvlad: compositor.log @ https://pastebin.com/TuFqK3FP14:30
tanmaytjmvlad: Looks like the systemd is unable to find the dri device, could be a permission issue14:30
tanmaytjsmurray: Running Fedora with kernel (AGL config)14:31
tanmaytjsmurray: Using podman instead of docker with following extra command line arguments to kernel14:31
tanmaytjsmurray: systemd.unified_cgroup_hierarchy=0 security=smack14:31
tanmaytjHOST systemd looks like this:14:32
smurraytanmaytj: okay.  The only other person I know of that has done this mentioned having to do a bunch of hacks, I've never tried it14:32
tanmaytjsmurray: Thanks, can you please let me how to get in touch with other person ?14:34
smurraytanmaytj: it was Tadao Tanikawa from Panasonic in Japan14:38
smurraytanmaytj: I'd suggest perhaps posting you question to the mailing list14:39
smurray*your14:39
*** walzert has quit IRC14:45
tanmaytjsmurray: Thanks a lot !14:50
smurraytanmaytj: there is work planned this year to integrate some version of Tanikawa-san's container demo from CES 2020, but nothing has started yet14:51
smurraytanmaytj: I think he mentioned having something on github wrt his demo, but I can't find it right off.   He used LXC, and at the moment that's what the instrument cluster expert group are proposing to use14:52

tanmaytjsmurray: Thanks for the information and update. Good to know that AGL support to run inside a container is in the pipeline !15:21
smurraytanmaytj: the IC EG folks want it, if you're interested, there are regular (every 2 weeks) meetings, see the wiki15:24
dl9pftanmaytj: smurray: https://github.com/agl-ic-eg15:27
dl9pftanmaytj: but mind this has not been touched for a year15:27
