7.1.2.1. Advanced Error Reporting (AER)

Each PCI Express compliant device must implement a basic level of error management and can optionally implement advanced error management. The PCI Express Advanced Error Reporting Capability is an optional Extended Capability that may be implemented by PCI Express device functions supporting advanced error control and reporting.

The P-Tile Avalon® -ST IP for PCI Express implements both basic and advanced error reporting. Error handling for a Root Port is more complex than that of an Endpoint. In this IP, the Physical Functions (PFs) are always capable of AER (enabled by default). There is no AER implementation for Virtual Functions (VFs).

Use the AER capability of the IP to identify the type of error and the protocol stack layer in which the error may have occurred. Refer to the PCI Express Capability Structures section of the Configuration Space Registers appendix for the AER Extended Capability Structure and the associated registers.
