摘要:
A method of routing data in an information handling system can include receiving a notification from a management controller at a basic input/output system (BIOS) that includes a system management interrupt (SMI) handler. The a notification can indicate that the management controller has a data packet bound for a peripheral component interconnect express input/output (PCIe I/O) device coupled to a secondary processor. The method can include generating a system management interrupt at the information handling system via the BIOS SMI handler in response to the notification. The method can also include retrieving the data packet from the management controller via the BIOS SMI handler and sending a payload associated with the data packet from the BIOS SMI handler to the PCIe I/O device.
