Abstract: Aspects of the embodiments are directed to systems and methods for performing link training using stored and retrieved equalization parameters obtained from a previous equalization procedure. As part of a link training sequence, links interconnecting an upstream port with a downstream port and with any intervening retimers, can undergo an equalization procedure. The equalization parameter values from each system component, including the upstream port, downstream port, and retimer(s) can be stored in a nonvolatile memory. During a subsequent link training process, the equalization parameter values stored in the nonvolatile memory can be written to registers associated with the upstream port, downstream port, and retimer(s) to be used to operate the interconnecting links. The equalization parameter values can be used instead of performing a new equalization procedure or can be used as a starting point to reduce latency associated with equalization procedures.
