Error Classification
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.
