The TSC meets on an irregular basis, but is happy to hold meetings on request if there are issues to discuss.
Meetings are usually held in #oe-tsc on Libera Chat on 3rd Monday of each month 9PM UTC (10PM UTC during winter time).  


The TSC discusses technical issues for the direction of OpenEmbedded. Note that the TSC is NOT chartered with actually doing all of the work discussed, but they do make every effort to locate resources to do that work.

Note: The Yocto Project also has a TSC.  Its responsibilities include repositories hosted on [[https://git.yoctoproject.org/|the Yocto Project git server]], the associated mailing lists, bugzilla, the testing processes and infrastructure/QA and the releases of the project.  For more information on that, go to [[https://wiki.yoctoproject.org/wiki/TSC|the Yocto Project wiki]]

OE Technical Steering Committee

The TSC consists of 5 people who are elected by, and ultimately be answerable to, the members of the OpenEmbedded organization.

Here is the working copy of the new TSC charter.

Meetings are usually held in #oe-tsc on Libera Chat on 3rd Monday of each month 9PM UTC (10PM UTC during winter time).

The TSC discusses technical issues for the direction of OpenEmbedded. Note that the TSC is NOT chartered with actually doing all of the work discussed, but they do make every effort to locate resources to do that work.

Note: The Yocto Project also has a TSC. Its responsibilities include repositories hosted on [Yocto Project git server], the associated mailing lists, bugzilla, the testing processes and infrastructure/QA and the releases of the project. For more information on that, go to [Yocto Project wiki]

Members

In order by name:

  • Bruce Ashfield (zeddii) re-elected Sep 2023
  • Joshua Watt (JPEW) re-elected Sep 2023
  • Richard Purdie (RP) - re-elected Sep 2023
  • Tim Orling (moto-timo) - elected Sep 2023
  • Jan-Simon Möller (dl9pf) - elected Sep 2023

Each member serves a two-year term.

Responsibilities

On a day-to-day basis the TSC is responsible for making tactical policy decisions, resolving disputes between contributors, administering access control to the git tree, and generally promoting good development practice.

Decision Making

Decisions are made where necessary by majority vote. Once a decision is made by the technical steering committee, the decision should be respected as a democratic decision.

Contacting the TSC

If you have an issue or would like something discussed at the next TSC meeting, please email tsc@lists.openembedded.org

The item will be added to the TSC topics discussed in the next meeting (or an adhoc meeting will be held is determined to be an urgent issue).

Alternatively, you can contact one of the TSC members listed above and ask them to add it to the list of items to be discussed.

TSC topics

This list keeps a running list of topics for the TSC.

  • Working Group Definition (https://www.openembedded.org/wiki/Working_Groups)
  • Layer Setup
  • Dublin Meetup
  • Talk about how to acknowledge contributions from community members
