Abstract

Methods, apparatus, and system to create interrupts which are resolved at runtime relative to an active compartment. Active compartments may be, for example, a compartment of an operating system (“OS”) or a trusted execution environment (“TEE”). The context-specific interrupts comprise an interrupt dispatch table (“IDT”) for each compartment.
