Does apple use psci too, hence that smc redirects to el2 extension they have?

I'm guessing that's so they can implement VMs that support PSCI but believe they're using the SMC mechanism instead of HVC.

Oh, yeah, that makes sense. Maybe also running older iPhone kernels expecting EL3 in VMs for their own internal dev too.
