TSC

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.

2024 Minutes

• 2024/10/21

 * Kanavin's setup layers/build setup
   * POC / set of patches, bitbake-setup-layers and bitbake-fragments
   * reviews by TSC members requested
 * SPDX3
   * done, discussed sstate issue
 * AutoBuilder 
   * intermittent issues causing a lot of debug work

• 2024/08/19

Attendees: Bruce, Jan-Simon, Josh, Tim

Topics:

• No topics. Meeting adjourned

Next call September 16th. Might be impacted by EOSS/ELCE/LPC in Vienna.

• 2024/07/15

Attendees: Steve G., Bruce, Tim, Josh, Richard

Topics:

• FIT image patch series
  • Some of the easier bits were merged
  • Remaining bits are now V2 on mailing list, needs review
• CVE standalone
  • Needs review by more experienced developers
• Kanavin's setup layers/build setup
  • Needs to be a priority for review
• SPDX3 in time for 5.1M2, may be impacted by JPEW vacation
• AutoBuilder storage and build sizes
  • LLVM build size
    • 240GB total, 40GB just for target LLVM package
    • -g1 drops to 4GB, without debug symbols ~700MB
    • General consensus is either option is ok, end user will make decision of when debug symbols are needed
    • Would be nice to have someone work on build-perf analysis as we roll out the new AB cluster
  • Next biggest offender is Rust
    • Rust reproducibility remains an issue for 'rustdoc' which continues to block upgrades
• QA Warnings as Errors
  • Moving towards YP Compatible requirement for higher quality layers
  • TMPDIR/build-path is needed for reproducible builds, but impacts go and rust recipes in meta-virtualization and meta-python
  • General consensus is this is moving in the correct direction; layers which have issues in AB will be identified as "help-wanted" recipes.
• meta-java
  • There is no CI, but adding to AB (even as a manual job) makes no sense with the current poor state of things
  • Will not get much attention until someone either fixes the active branches (kirkstone, scarthgap, master) or funds a dedicated effort to fix it
  • At least on Ubuntu 22.04 and Debian 12 hosts, none of those branches are currently buildable, since low level dependencies such as icedtea7-native fail to compile.
• Any outstanding things that should be added to 5.1?
  • Consensus is nothing on the radar that is not already in progress

Next call August 19th.

• YP and OE
