Method and system for ordering I/O access in a multi-node environment

A multi-chip system comprising:

• multiple chip devices, at least one chip device of the multiple chip devices including an input/output (I/O) device, and each chip device of the multiple chip devices including:
• an inter-chip interconnect interface configured to couple the chip device to one or more other chip devices of the multi-chip system,
• multiple agents configured to initiate operations for accessing the I/O device, and
• a queue configured to queue operation for accessing the I/O device generated by one or more agents of the multiple agents,
• wherein a first agent of the multi-chip system is configured to, upon initiating a first operation for accessing the I/O device, provide an indication of queuing the first operation in the queue prior to transmission of the first operation to the I/O device wherein the indication of queuing the first operation in the queue comprises modifying a value located in a memory component of the multi-node system, the first operation is queued in the queue of the multi-chip system;
• wherein a second agent of the multi-chip system is configured to monitor the value located in the memory component of the multi-node system, initiate a second operation to access the I/O device, in response to detecting the indication of queuing the first operation in the queue, the second operation is queued subsequent to the first operation in the queue;
• and
• the queue is further configured to transmit the first I/O operation to the I/O device and transmit the second I/O operation to the I/O device after transmitting the first I/O operation.
