Computing system fabric and routing configuration and description

摘要

A technique for configuring a computing system that allows for multiple computing systems and device populations to be supported by a single BIOS implementation is presented. In one embodiment, the technique includes processing topology map parameters that describe physical connections of a computing system, wherein the computing system includes a plurality of processing nodes; determining routing paths for traffic between the plurality of processing nodes; and determining a population of the plurality of processing nodes. In one embodiment, the determining the routing paths is performed during BIOS build time. In another embodiment, the determining the routing paths is performed during BIOS run time.

1. A method of configuring a computing system comprising:
processing topology map parameters that describe physical connections of the computing system, wherein the computing system includes a plurality of processing nodes; determining routing paths for traffic between the plurality of processing nodes; in the computing system, determining a population of the plurality of processing nodes using communication links coupling processing nodes of the computing system, wherein determining the population includes determining whether individual nodes of the plurality of processing nodes are populated with a corresponding device; and loading the routing paths according to the population into a node table of at least one populated processing node, wherein the determining the population of the plurality of processing nodes comprises sequentially checking for population and stopping the checking upon finding a first unpopulated processing node.
