Abstract
Data processing in a data processing system including a plurality of processing nodes coupled by a communication link includes receiving a first command from a first processing node. A link stall of the communication link is detected by a first link layer of the first processing node. A stop command is received at a first transaction layer of the first processing node from the first link layer. The first command is truncated by the first transaction layer into a first truncated command responsive to receiving the stop command. A command arbiter is instructed to stop issuing new commands. The first truncated command is forwarded to an asynchronous crossing buffer of the first processing node.
