Hi,
Linaro is conducting an opportunity assessment to make OP-TEE ready for functional safety sensitive environments. The goal is to present a plan to Linaro members by the end of July 2021. The scope of the research is somewhat bigger because we can’t think of OP-TEE without thinking of Trusted Firmware and Hafnium. The plan will though not address those (unless we recognize we have to). We don’t think U-Boot shall be part of the picture but we are welcoming contradictory points of views. We are organizing a 2 hours workshop on April 15th 9am CET to mostly hear about use cases and ideas about Long Term Support requirements . We will present the state of the research. The first use case is booting a safety certified type-1 hypervisor (open source or commercial is irrelevant). But we know there are many more: please be ready to contribute. We think of more radical use cases: a safety payload is actually loaded as a Secure Partition on top of Hafnium with OP-TEE or Zephyr used as a device backends. In other words, Trust Zone hosts both safety and security worlds , EL3 being the « software root of trust » pivot world. In those cases, some cores never go out of secure state… Agenda (to be refined) - Vision - State of the research <https://docs.google.com/presentation/u/0/d/1jWqu39gCF-5XzbFkodXsiVNJJLUN88BgkiBu__D5KeE/edit> - Use cases discussion - What is the right scope? - “Who do what” discussion (LTS, archiving...) - Safety personnel (Linaro and contractors) discussion - Other considerations from participants? - Community organizations and funding? - Closing and next steps Should you want to participate and have not yet received an invite, please contact me directly. Cordially, François-Frédéric PS: Please reach out should you want another date with a time compatible with more time zones. This alternate date is not guaranteed though. -- François-Frédéric Ozog | *Director Linaro Edge & Fog Computing Group* T: +33.67221.6485 francois.o...@linaro.org | Skype: ffozog _______________________________________________ boot-architecture mailing list boot-architecture@lists.linaro.org https://lists.linaro.org/mailman/listinfo/boot-architecture
