In addition to detecting errors, a Root

Port also gathers and manages errors sent

by downstream components through the

ERR_COR, ERR_NONFATAL, AND

ERR_FATAL Error Messages. In Root

Port mode, there are two mechanisms to

report an error event to the Application

Layer:

serr_out

output signal. When set,

indicates to the Application Layer that

an error has been logged in the AER

capability structure

aer_msi_num

input signal. When the

Implement advanced error reporting

option is turned on, you can set

aer_

msi_num

to indicate which MSI is

being sent to the root complex when

an error is logged in the AER

Capability structure.
