What would you consider the “RISC-V equivalent” of TrustZone? Last time I was curious I didn’t find anything.
(FWIW I agree with the other commenter that these ""security"" features are useless, and feel to me more like check-box compliance than anything else (Why does TrustZone work with function calls? What’s wrong with IPC! Also, what’s wrong with privileged mode?). Just seems like a bit of a waste of silicon really.)
