10. 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.

10.1 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.

10.1.1 PCI Express Correctable errors

When a PCI Express correctable error is reported to the BIOS SMI handler it will record the error using the following format.
