Abstract:
Bridging strongly ordered write transactions to devices in weakly ordered domains, and related apparatuses, methods, and computer-readable media are disclosed. In one aspect, a host bridge device is configured to receive strongly ordered write transactions from one or more strongly ordered producer devices. The host bridge device issues the strongly ordered write transactions to one or more consumer devices within a weakly ordered domain. The host bridge device detects a first write transaction that is not accepted by a first consumer device of the one or more consumer devices. For each of one or more write transactions issued subsequent to the first write transaction and accepted by a respective consumer device, the host bridge device sends a cancellation message to the respective consumer device. The host bridge device replays the first write transaction and the one or more write transactions that were issued subsequent to the first write transaction.
