Description Yvugenfi@redhat.com 2020-07-16 10:18:14 UTC

Description of problem:
According to MS requirements for WHQL certifications for the next version of Windows Server, PCIe devices must support AER:
>>>
“Device.DevFund.Server.PCI.PCIAER - Windows Server PCI Express devices are required to support Advanced Error Reporting [AER] as defined in PCI Express Base Specification version 2.1.”
Description

See Tables 6-2, 6-3, 6-4, and 6-5 of the PCI Specification on how errors are detected in hardware, the default severity of the error, and the expected action taken by the agent which detects the error with regards to error reporting and logging.
All three methods of error reporting; completion status, error messages, error forwarding\data poisoning. Completion status enables the Requester to associate an error with a specific Request.

Error messages indicate if the problem is correctable or not, and fatal or not
Error forwarding\data poisoning can help determine if a particular Switch along the path poisoned the TLP
