SRESTORE

Operation

Restores the base supervisor-state record.

Assembler Syntax

SRESTORE [Rn(r)]

Privilege

Supervisor only

SRESTORE reads one 8-byte base supervisor-state record from the 8-byte-aligned address captured from Rn. It requires bits 63 through 17 to be zero and validates the complete STATUS and DFA event-state combination before atomically replacing them. A fault leaves architectural state unchanged.
