Broadcast translation lookaside buffer invalidation

Abstract

Techniques for broadcast translation lookaside buffer invalidation are described. In some examples, an instance of a single instruction includes fields for a single instruction having fields to indicate one or more operations to perform, an identifier of a first source operand, and, in some examples, an identifier of a second source operand is to be handled by execution circuitry. The execution circuitry of a first hardware thread is to execute the decoded instruction according to the fields to indicate one or more operations to broadcast a command to a plurality of hardware threads to cause an invalidation one or more translation lookaside buffer (TLB) entries for each of the plurality of hardware threads in accordance with a value of the first source operand and/or a value of the second source operand.
