ABSTRACT:
The present invention provides for a method and system for allowing non-trusted partitions in large scale computer system to safely interrupt a processor without the risk of corruption or loss of interconnect bandwidth, and without the need for inefficient hardwiring. In operation code preferably located outside of the central processor, interrupts coming from outside the partition into specific addresses for determination of allowability into the partition.
