Abstract:
1. An apparatus comprising: input/output (“I/O”) logic, at a computing system, coupled to a point-to-point interconnect to couple caching agents and home agents, the I/O logic including a physical layer to receive an operation based on an interrupt generated in response to an insertion or removal of a resource, wherein, in response to the physical layer receiving the operation, the I/O logic to enter a state where no protocol transactions are generated, and wherein during state routing, routing tables associated with the resource are updated without rebooting an operating system (“OS”) of the computing system by firmware performing a quiesce operation of the caching agents and the home agents on one or more partitions; and dynamic configuration logic to facilitate at least one of on-line addition and on-line deletion of the resource relating to at least one of the one or more partitions without requiring the rebooting of the OS, wherein the on-line addition of an individual resource comprises performing physical and logical set up for the individual resource, defining common system interface (CSI) links between a running system (RS) and the individual resource, setting a path from the individual resource to a firmware, running self test and initialization on the individual resource, indicating to firmware execution on the RS that the individual resource is ready to join at least one partition, and indicating to the OS on the RS that the individual resource is ready to join at least one partition.
