Global Error Reporting
A more detailed architectural view of all SoC error handling is shown in
Figure 4-3
.
The SoC detects errors from the PCIe* links and the SoC internal device errors. The
errors are first logged and mapped to an error severity, and then mapped to a system
event(s) for error reporting.
SoC error-reporting features are summarized below. Details are in the following
sections.
• Detects and logs PCIe links and SoC internal device errors.
• First error/next error detection and logging for correctable/uncorrectable local
• First error/next error detection and logging for correctable/uncorrectable local
errors.
• Allows flexible mapping of local uncorrectable errors to fatal or non-fatal error
classes.
• First/next error detection and logging for correctable, non-fatal, and fatal global
errors.
• Flexible error reporting using multiple reporting mechanisms.
• Supports PCIe error reporting mechanism based on the Root Complex Event
• Supports PCIe error reporting mechanism based on the Root Complex Event
Collector (RCEC).
The SoC provides direct mapping of system errors to NMI or SMI. The System Error
(SERR) mechanism is not used to do this.
