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.
