Abstract
An apparatus and method for supporting communication during error handling in a computing system. A computing system includes a first partition and a second partition, each capable of performing error management based on a respective machine check architecture (MCA). When a host processor in the first partition detects an error that requires information from processor cores of the second partition, the host processor generates an access request with a target address pointing to a storage location in a memory of the second partition, not the first partition. When the host processor receives the requested error log information from the second partition, the host processor completes processing of the error. To support the host processor in generating the target address for the access request, during an earlier bootup operation, the second partition communicates the hardware topology of the second partition to the host processor.
