(Linaro not available due to internal offsite meeting)
* Dan: No roadmap updates this month due to unavailability of Linaro and Arm technology manager
* Dan: Expecting combined TF-A + Trusted Services roadmap next month. OP-TEE roadmap is also due.
* Dan: Don wanted to raise again the risk of Phabricator being deprecated (that we use for wiki content)
* Dan: It's not getting security updates and we have had issues with rogue accounts being created
* Dan: Now the task to create GitHub mirrors for all projects (https://linaro.atlassian.net/browse/TFC-247) is mostly complete, we can progress with migrating wiki content there
* Dan: Propose that we ping maintainers to start migrating project information. Can also directly migrate generic content (e.g. community pages).
(No objections)
Action: Dan and Antonio to ping maintainers to start migrating project information. Also directly migrate generic content (e.g. community pages).
Shebu presented attached slides on TF-M LTS proposal.
* AndreJ: TF-M has a dependency on MCUBoot and MBedTLS. Will they have the same LTS policy?
* Shebu: Yes, Mbed TLS has similar LTS schedule that is proposed for TF-M (2 concurrent LTS, each with 3-year lifetime). Slide 6 shows integration plan.
* We thought about doing this for MCUBoot too but as it is a small project, we think we can live with backporting security fixes as required. No plans currently.
* Dan: So, no releases from main branch? Why not?
* Shebu: Such releases wouldn't be usable for PSA certification.
* Shebu: This would save effort, which could be used for LTS maintenance instead
* Shebu: One possible use-case is for RSS releases.
* Shebu: One consequence is that users would have to wait for the next LTS to get latest features in a release (up to 18 months)
* Shebu: Expect that we'll need to backport new platform ports to LTS branches
* Shebu: Platforms can't wait until next LTS release.
* Ruchika: I also think main branch releases would be good as not everyone will be consuming LTS. 18 month wait could be too long.
* Ruchika: Would help platforms that don't need certification but do need new features.
* Shebu: We would need to work out how we could resource main branch releases. Probably wouldn't have the same level of support as LTS releases.
* Shebu: We'll need help from TF-M users using PSA Certified to resource the LTS releases
* Shebu: Going to present this in TF-M Tech forum.
* Shebu: Have already mentioned it to the TF.org board.
* Shebu: This is only tentative until we get approval from certification lab
* Shebu: Need to know from members if this will break their distribution model somehow
* Dan: So the plan is to get feedback from the lab and members, then go to the TF-M tech forum?
* Shebu: Yes.
Hi TSC
Let me know if you have any discussion topics for tomorrow. So far I have:
* TF-M LTS branch (Shebu).
* OP-TEE or Trusted Services roadmap (TBC).
Regards
Dan.
