Documentation/powerpc: Ultravisor API

2019-08-29T23:40:15Z

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.

docs: powerpc: convert docs to ReST and rename to *.rst

2019-07-17T09:57:51Z

Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
