System and method for programming hyper transport routing tables on multiprocessor systems

摘要

In some embodiments, present invention describes a system and method of dynamically programming HT tables in multiprocessor systems. HT tables are dynamically reprogrammed to modify the topology of the multiprocessor system for fault adjustment, diagnostic, performance analysis, processor hot plugging and the like. HT links can be isolated by reconfiguring the HT tables which allows diagnostics on the isolated HT links. HT links can be reconfigured to route packet traffic on certain links which allows the performance measurement for the HT links. HT tables can be reconfigure to isolate a processor so that the processor can be replaced without taking the entire system down.
