Summary:A port is to couple to another die over a die-to-die (D2D) link and includes a die-tio-die (D2D) adapter to determine, from a set of registers, a set of capabilities of the D2D adapter to advertise in a negotiation with a link partner D2D adapter, where the D2D adapter is on a die and the link partner D2D adapter is located on a remote link partner die. A first capabilities advertisement message is sent to the link partner D2D adapter to advertise the set of capabilities to the link partner D2D adapter. A second capabilities advertisement message is received from the link partner D2D adapter, wherein the second capabilities advertisement message identifies a set of capabilities of the link partner D2D adapter. A final configuration of a D2D link is determined to couple the die to the link partner die.
