RX TX No Yes No 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.
