Abstract
Methods and systems are disclosed that relate to handling interrupts across multiple software instances. An exemplary method includes receiving an interrupt at a current CPU. An instance includes a set of independent threads of execution each with its own code context, interrupt service routines, drivers, and operating system services. The method further includes storing context information relating to the first instance, identifying the second instance associated with the interrupt, running at least one interrupt service routine, and restoring the context information relating to the first instance.
