Abstract:
1. A method in a data processing system for preventing said system from crashing when a parity error occurs in a cache that is associated with a processor included in said system and for processing said parity error during runtime of said system, the method comprising: responsive to an occurrence of a parity error in said cache that is associated with said processor, storing a single set of processor information, that indicates an error type, error states, and error status that are stored in said processor as a result of said occurrence of said parity error, in registers in said processor to form stored processor information; determining whether the parity error is a recoverable parity error using the stored processor information by reading said registers to analyze said stored error type, error states, and error status; and responsive to the parity error being a recoverable parity error, performing a recovery action.
