Some have. Some not. Some have it and it's owner-controllable. It's not
about the ISA and some optional architectural feature, it's about the
chip you buy.

Forget it. RISC-V already has SMM like tech in the architecture. But
that doesn't matter as long as you can buy chip's that are owner con-
trollable. Such features make it harder to keep everything secure but
they don't force the silicon vendor to lock you out (as long as you
don't ask to be able to watch Netflix in high resolution or something
like that).
