Method and apparatus for interconnect built-in self test based system management performance tuning

A method comprising:

• driving an interconnect that connects a first device and a second device of a post-production system with a set of test data and a set of tuning operating parameters;
• measuring operating conditions of the interconnect driven by the set of test data and the set of tuning operating parameters;
• modifying the set of tuning operating parameters at least once;
• measuring operating conditions of the interconnect each time the set of operating parameters are modified;
• determining an optimal measured operating condition from the plurality of measured operating conditions;
• and
• selecting the set of tuning operating parameters that resulted in the optimal measured operating condition to be actual operating parameters for the post-production system.

An apparatus comprising:

• an interconnection that connects a first device to a second device;
• the first device having,
• a first interconnection operating condition measurement logic to measure post-production operating conditions of the interconnection with respect to the first device with a first set of test data and a first set of tuning operating parameters,
• a first set of one or more non-volatile memory to store results generated by the first interconnection operating condition measurement logic;
• the second device having,
• a second interconnection operating condition measurement logic to measure post-production operating conditions of the interconnection with respect to the second device with a second set of test data and a second set of tuning operating parameters,
• a second set of one or more non-volatile memory to store results generated by the second interconnection operating condition measurement logic;
• and
• a platform tuning management subsystem coupled with the first and second device, the platform management subsystem having a set of tuning operating parameters, and the platform tuning management subsystem to set actual operating parameters in accordance with tuning operating parameters that result in a best measured test operating condition.
