System and method for virtualizing processor and interrupt priorities
Dispatching of interrupts to a processor is conditionally suppressed, that is, only if an old priority value and a new priority value are either both less than or both greater than a maximum pending priority value. This conditional avoidance of dispatching is preferably implemented by a virtual prio...

| Zusammenfassung: | Dispatching of interrupts to a processor is conditionally suppressed, that is, only if an old priority value and a new priority value are either both less than or both greater than a maximum pending priority value. This conditional avoidance of dispatching is preferably implemented by a virtual priority module within a binary translator in a virtualized computer system and relates to interrupts directed to a virtualized processor by a virtualized local APIC. |
