From: Sukadev Bhattiprolu <redacted> Protected Execution Facility (PEF) is an architectural change for POWER 9 that enables Secure Virtual Machines (SVMs). When enabled, PEF adds a new higher privileged mode, called Ultravisor mode, to POWER architecture. Along with the new mode there is new firmware called the Protected Execution Ultravisor (or Ultravisor for short). POWER 9 DD2.3 chips (PVR=0x004e1203) or greater will be PEF-capable. Attached documentation provides an overview of PEF and defines the API for various interfaces that must be implemented in the Ultravisor firmware as well as in the KVM Hypervisor. Based on input from Mike Anderson, Thiago Bauermann, Claudio Carvalho, Ben Herrenschmidt, Guerney Hunt, Paul Mackerras.
