Abstract
Techniques relating to virtual idle loops are described. In an embodiment, decoder circuitry decodes a single instruction. The single instruction includes a field for an identifier of a first source operand, a field for an identifier of a second source operand, a field for an identifier of a destination operand, and a field for an opcode. Execution circuitry executes the decoded instruction according to the opcode to: write the first source operand to a memory location identified by the second source operand; compute an index into a control array based at least in part on the destination operand; and determine whether to exit to a hypervisor of a Virtual Machine (VM) based at least in part on data stored at a location in the control array, wherein the location is to be identified by the computed index. Other embodiments are also disclosed and claimed.
