PCI Express* and Legacy PCI Subsystem

The PCI Express* (PCIe) Specification defines standard error types under the Advanced Error Reporting (AER) capabilities. The
BIOS logs AER events into the SEL.
The Legacy PCI Specification error types are PERR and SERR. These errors are supported and logged into the SEL.
8.1

PCI Express* Errors

PCIe error events are either correctable (informational event) or fatal. In both cases information is logged to help identify the source
of the PCIe error and the bus, device, and function is included in the extended data fields. The PCIe devices are mapped in the
operating system by bus, device, and function. Each device is uniquely identified by the bus, device, and function. PCIe device
information can be found in the operating system.
8.1.1

Legacy PCI Errors

Legacy PCI errors include PERR and SERR; both are fatal errors.
