ABSTRACT:
Systems, methods, and apparatus to retarget platform interrupts in a reconfigurable system. Some embodiments include identifying each processor of a multiprocessor system capable of processing Corrected Platform Error Interrupts, adding each processor capable of processing Corrected Platform Error Interrupts to a list of potential Corrected Platform Error Interrupt targets, and updating an interrupt table with a target processor for an interrupt, wherein the interrupt table is accessible by an interrupt controller to target platform interrupts. Another embodiment includes receiving a request to disable the first processor in a multiprocessor apparatus, determining if the first processor is a Corrected Platform Error Interrupt destination, and determining if the second processor is capable of processing Corrected Platform Error Interrupts. This embodiment also includes reprogramming an interrupt controller to route interrupts to the second processor instead of the first processor and disabling the first processor.
