 10.2.6.2.1. SLB Invalidate Selection Register (SLBI_Select_An)
       

The SLB Invalidate Selection Register (SLBI_Select_An) contains the process identifier (PID) used to select which SLB entries to invalidate.

 This facility is used by the system software to specify the PID for a more selective SLB invalidation.

 There is one register for each PSL slice. Access to these registers should be privileged. These registers must be accessed using a single 64-bit store operation.
