Advanced Error Reporting
AER (Advanced Error Reporting) is
a PCI Express feature that allows for more
enhanced reporting and control of errors than the basic error reporting scheme
. AER
errors are categorized as either correctable or uncorrectable and can be detected by the
test software.
Correctable errors include those error conditions where hardware can recover without
any loss of information. Hardware corrects these errors and software intervention is
not required.
Uncorrectable errors are those error conditions that impact functionality of the
interface. There is no mechanism defined by PCIe specification to correct these errors.
The below table summarize the list of errors that can be detected by the PCIe Gen3
Test card.
