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…
