 9.3. Ordering Rules

 The CAIA follows the same ordering rules as the POWER architecture. Because the POWER architecture is a weakly ordered memory model, the PSL must provide a means for an AFU to order operations.

 A typical PSL implementation provides a completion status for each operation. When the AFU receives a successful completion status, the corresponding operation is guaranteed by the PSL and system to be visible to all units in the system and is ordered with any subsequent operations.
