# metadata.contentDescription
This document defines a programmers’ model interface for Statistical Profiling Extension (SPE) and Trace Buffer Extension (TRBE) called the 'Virtual machine interface for SPE and TRBE'. The 'Virtual machine interface for SPE and TRBE' is defined to be used by an operating system that might be run under a hypervisor, but retains compatibility with the bare metal interface.
