Description

Provides a synchronization point ensuring that all slbieg and slbiag instructions executed by the current thread prior to this instruction have completed their effects before any subsequent memory operations are visible. This is a privileged instruction with no operands that enforces ordering of segment lookaside buffer (SLB) invalidation operations.

Operation

Synchronize all prior slbieg and slbiag effects

Programming Note

slbsync should not be used to synchronize the completion of slbie.
