Abstract
A method and circuit for implementing exchange of failing lane information for fault-tolerant communication links, and a design structure on which the subject circuit resides are provided. An ordered set for lane and link training includes a novel lane mask field for lane and link training. Ordered sets are exchanged during lane and link training for a fault-tolerant communication link to establish synchronization between a transmitter and a receiver. In a link training step, the bus link layer exchanges an ordered set with a plurality of bits of lane mask information included in predefined bytes, such as bytesandof the lane mask field. Upon receiving the ordered set with the plurality of bits of lane mask information, the transmitter lanes are reconfigured to align with the received mask information.
