Errors are classified as two types: uncorrectable and correctable. This classification 

separates those errors resulting in functional failures from those errors resulting in 

degraded performance. Uncorrectable errors are further classified as fatal or non-fatal. 

Classification of error severity as fatal, non-fatal, and correctable provides the platform 

with mechanisms for mapping the error to a suitable handling mechanism. Each 

severity triggers a system event according to the mapping defined by the System Event 

Map register. This mechanism provides the software the flexibility to map an 

uncorrectable error to the suitable error severity. For example, a platform may choose 

to map an uncorrectable ECC error as an non-fatal error while another platform design 

may require mapping the same error to a fatal error. The uncorrectable error mapping 

is set to the default mapping at power-on so it is consistent with the default mapping 

defined in 

. The software/firmware chooses to alter the default mapping after 

power-on.
