1. A system comprising:
a first device configured to:
receive a link configuration policy, wherein the link configuration policy indicates an association relationship between a first unidirectional logical lane and a first unidirectional physical lane; and
configure a high-speed serial link according to the link configuration policy; and
a second device comprising a first interface configured to:
couple to the first device with the high-speed serial link, and
send the link configuration policy to the first device based on a status of a receiver of the first interface,
wherein the link configuration policy comprises a physical lane on which the receiver detects a pulse for positioning an associated forward logical lane, and the link configuration policy excludes any physical lane on which detecting the pulse is less clearly or easily detected,
wherein the first unidirectional logical lane is from the first device to the second device in the high-speed serial link, and
wherein the first unidirectional physical lane is from the first device to the second device in the high-speed serial link.
