Abstract

A card having a first device and a second device is plugged into a root port having a predefined root port width. The first device is trained and the device lane width is determined. If the root port width is greater than the device lane width then the root port is dynamically configured via hardware strapping to include a predefined number of adjacent ports with each port having a lane width equal to the device lane width. The root port is reset to force training of the first device and the second device.
