PCIE AERMetricUncorrectable ErrorTextuncorrectableMasterpcie_errorsThe errors which don’t have impact on integrity of the PCI Express fabric, but data/information is lost. Non-fatal errors are corrupted transactions that can’t be corrected by PCIe hardware.
However, the PCI Express fabric continues to function correctly and other transactions are unaffected, only particular transaction is affected. Recovery from a non-fatal error may or may not, depends on device-specific software associated with the requester that initiated the transaction
None

PCIe AERMetricCorrectable ErrorTextcorrectableMasterpcie_errorsthe errors which may have an impact on performance (like latency, bandwidth), but no data/information is lost and PCIe fabric remains reliable. Such errors are corrected by hardware and no software intervention is requiredNone

PCIe AERMetricSeverity Fatal ErrorTextfatalMasterpcie_errorsError severity indicating reboot necessaryNone

PCIe AERMetricUnsupported RequestTextunsupportedMasterpcie_errorsThis error occurs when an endpoint or a root port recieves any of a set of transactions as defined by PCIe Spec defined in [1]. In all cases the TLP is deleted in the Hard IP block and not presented to the Application Layer. If the TLP is a non-posted request, the Hard IP block generates a completion with Unsupported Request status.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricData Link Protocol Uncorrected ErrorTextData Link ProtocolMasterpcie_errorsThis error occurs when a sequence number specified by the Ack/Nak block in the Data Link Layer (AckNak_Seq_Num) does not correspond to an unacknowledged TLP.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricPoisoned TLP Uncorrected ErrorTextPoisoned TLPMasterpcie_errorsanytime a poisoned TLP is destined to PCIe device, IIO module will drop the poisoned data packet, contain the error in the domain that it was detected in, bring down the link, and signal a fatal error to SW/FWDepends on what's exposed in sysfs and proc file systems

PCIe AERMetricFlow Control Protocol Uncorrected ErrorTextFlow Control ProtocolMasterpcie_errorsAn uncorrected error in flow control protocol found in transaction layer that prevents flow control credits transactions being sent. This error occurs when a component does not receive update flow control credits with the 200 µs limit.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricCompletion Timeout Uncorrected ErrorTextCompletion TimeoutMasterpcie_errorsThis error occurs when a request originating from the Application Layer does not generate a corresponding completion TLP within the established time. It is the responsibility of the Application Layer logic to provide the completion timeout mechanism. The completion timeout should be reported from the Transaction Layer using the cpl_err[0] signal.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricCompleter Abort Uncorrected ErrorTextCompleter AbortMasterpcie_errorsThe Application Layer reports this error using thecpl_err[2]signal when it aborts receipt of a TLP.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricUnexpected Completion Uncorrected ErrorTextUnexpected CompletionMasterpcie_errorsThis error is caused by an unexpected completion transaction as listed in [1]. The TLP is not presented to the Application Layer; the Hard IP block deletes it.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricReceiver Overflow Uncorrected ErrorTextReceiver OverflowMasterpcie_errorsThis error occurs when a component receives a TLP that violates the FC credits allocated for this type of TLP. In all cases the hard IP block deletes the TLP and it is not presented to the Application Layer.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricMalformed TLP Uncorrected ErrorTextMalformed TLPMasterpcie_errorsThis error is caused by an unexpected completion transaction as listed in [1]. The TLP is not presented to the Application Layer; the Hard IP block deletes it.Depends on what's exposed in sysfs and proc file systems

PCIe AERMetricECRC Uncorrected Error StatusTextECRCMasterpcie_errorsECRC ensures end-to-end data integrity for systems that require high reliability.
