OpenEmbedded eV General Assembly
We have a short administrative meeting before starting the Developer meeting. All are welcome for this.
- Proposal to dissolve the current e.V. and re-constituting it in the U.S. to reduce the administrative burden for the project.
- Define a method for identifying lapsed memberships.

Agenda
-
Metadata-
OVERRIDE syntax: is it time to reconsider _? -
meta-yocto -> meta-poky. People are still spending too much time explaining reality. (Crofton) -
variable expand = True by default
-
-
BSPs (tlwoerner)-
Standards for BSP behavior. (Crofton) -
feedback on layerindex to indicate BSP:- last successful compile (feedback from outside builders?)
- last successful boot
- master branch parsability (perhaps ties into bugzilla 7792?)
-
-
several BSP layers to choose from for some boards, none for others (linux.com SBC survey) -
guidelines/requirements for setting up a new BSP on layerindex- bugzilla
- mailing list (use general mailing list(s) for patches?)
- git.yoctoproject.org/<yourbsplayer>
- should a BSP layer ever use = ?
Processes-
LayerIndex feature requests (tlwoerner) - build feedback (autobuilders and off-site)
- Build and test failures on the public Autobuilder (Bluelightening)
-
- Systemd
- Systemd packaging. As new things appear, they are lumped into one package. Update split? (Crofton relaying info)
- Can we get systemd's first-boot support to work? It is currently disabled in the systemd recipe by touching /etc/machine-id. (Saur)
- How to make it easy to setup a system "the systemd way"? New DISTRO_FEATURE or IMAGE_FEATURE? (Saur)
- Link /bin -> /usr/bin, /lib -> /usr/lib, etc.
- Change ${systemd_unitdir} to /usr/lib.
- Make the systemctl wrapper install in ${systemd_unitdir} rather than ${systemconf}/systemd.
- This should also happen when installing a package in runtime.
- Advocacy
- There are still a lot of projects (too many?) not using OE (tlwoerner)
- why aren't more projects using OE?
- how can we get more people using OE?
- who should we be targeting? (build people (obviously), kernel devs? user-space devs?)

BSPs & Layer Index
Paul described layer index process & how it works BBP layers also come into toaster, expose to people, dependency list very important - snapshot when setting up toaster module branches - will look in repo for branches some layers don't have a master branch, don't show content - need way to present in UI REST API DD automatically parse layer to check for required content? PE do want, necessitates background queuing process parse w/dependencies also affects YP Compatible, RP's proposed layer validation tool error reporting system - tie together with info in layer index, intention there JH ability to register layer & specify quality ------------------------------------------ not getting resources to work on core BSPs people working on own BSPs - not really a complaint, but an observation SH would love to see REST APIs PE would love some help with the layer index RP love ideas, but people need to resource, step up & drive ------------------------------------------ => oe driving toward machine readable files, can also drive from layer test (yp compat) side - KK ------------------------------------------ oe-core or oe-devel? oe-core ------------------------------------------ => publicize defs of each list? discuss on members list - where to overall architecture discussions belong discussion: decided on oe-core oe needs its own goals, interact with the yocto project ------------------------------------------ status email to oe-core list, useful? to most people. cross-postd to yocto list KK should be about oe-core, not about poky => TSC to add new mailing list specifically about project architecture, no patches, and determine list name ------------------------------------------ KK realize that OE has no project vision RP is there any vision that needs to be represented to YP, and are there resources KK as a project take an active role to work with YP marketing/visibility standpoint, wear OE hat if list of oe bugs that should be raised, bring to philip -> KK bring discussion to new mailing list ------------------------------------------ TW can new layers use bugzilla PE struggle with volume of bugs currently in triage process RP triage process - yp has taken on oe-core eg. don't want many bugs from idle layers, YP judged on metrics from that system SW some layers already in that state DD attended call regularly RP maintainers must be willing to come to triage process some issues don't have a clear maintainer ------------------------------------------ BSP standards - standards exist,coming soon are methods for comparing a given layer with the standard "oe has no rules, only half-documented best practices" - Koen => need wiki documentation for TSC to ratify -> document distro vs. machine policies, other best practices ------------------------------------------ BSP layer availability -> encourage board vendors to provide a BSP, make it easier to do so people problem, not technical problem add questionnaire about why people don't ask LF to include a list of BSPs that are supported => ask yp ab to talk to linux.com [PB] - community issue build for qemu, with limited resources -> look at digi manual (i.e. "just add bsp changes in local.conf") best practices : should be easy to use, instructions/tools to put it on a card, etc wic incomplete but promising ------------------------------------------ touching variables - discuss on new arch list ------------------------------------------
Metadata
meta-yocto to meta-poky:
=> RP to take action on the YP side, possibly not for 2.0
override syntax
underscore character to designate overrides, underscore is overloaded need better method KK maybe _OVERRIDE_ dot character? require all lowercase overrides? benefits for bitbake speed => formalize lowercase as mandatory requirement for overrides, look for other options in the future
Processes
Layer Index feature requests discussed with layer index build feedback>>
Build/test failures on public autobuilder
problems: RP different failures "random" - actually is a pattern, but initially looks random build poky and poky-lsb, lsb turns on different distro features boots a machine in qemu & runs scripts, most qemu machines, just says "kill" - unknown release blocker causing qa failures also, systemd having timeout issues should OE care about these things? (yes) PE set up environment to detect regressions did upgrading qemu and systemd create these? get to a correct point not poky changes or bsp changes eg poky enables ptest, doesn't affect systemd timeout RP have massively increased scope of tests ptests, sdk.. resources always an issue -> ask for cycles from employers to work on these issues -> make people aware, help with triage, provide resources KK -> plan B, C, etc. have had this problem for years more issues recently
Systemd
Security
security a long term issue, beginning to be noticed - now reluctant to address it, as it is being noticed/resourced if patch had standard cv, could write automated tools to parse -> need a method for tracking CVs MH have to have someone whose job it is to pull CV list, look for differences, assess applicability Michael Halstead : LF can run security audits of individual tools could do layer index, toaster, ... busybox MH independent academic audit found OE very good
Advocacy
why aren't more projects using OE? how can we get more people using OE? who should we be targeting? build people, kernel devs, userspace devs
