System and method for allowing non-trusted processors to interrupt a processor safely

A module for allowing a processor located outside a partition to safely communicate interrupts to a target processor located within said partition, said module comprising:

• a chipset that receives for receiving a transaction directed to said in-partition processor, and that is physically separate from said target processor;
• a determination module that determines a location of said source processor;
• a transaction module that drives a transaction from a source processor determined to be within said partition to said target processor;
• an evaluation module that evaluates a transaction from a source processor determined to be outside said partition, and determines if said out-of-partition transaction is an interrupt;
• a modification module that structurally alters out-of-partition interrupts;
• and
• an allowance module that drives altered out-of partition interrupts to said target processor.

Computer readable code, stored on a computer readable medium, said code comprising:

• code for determining a source of a transaction directed to a target processor, wherein said target processor is located within a computer system partition, and wherein said source determining code determines if said source is located inside or outside said partition;
• code for determining a nature of a transaction determined to have an out-of-partition source, wherein said nature determining code determines if said out-of-partition transaction is an interrupt;
• code for performing at least one bitwise operation on said out-of-partition interrupt that structurally alters said out-of-partition interrupt;
• and
• code for driving said alleged out-of-partition interrupt to said target processor.
