Expand description

Controls the use of instructions related to Pointer Authentication:

In EL0, when HCR_EL2.TGE==0 or HCR_EL2.E2H==0, and the associated SCTLR_EL1.En==1.
In EL1, the associated SCTLR_EL1.En==1.

Traps are reported using EC syndrome value 0x09. The Pointer Authentication instructions trapped are:

AUTDA, AUTDB, AUTDZA, AUTDZB, AUTIA, AUTIA1716, AUTIASP, AUTIAZ, AUTIB, AUTIB1716,
AUTIBSP, AUTIBZ, AUTIZA, AUTIZB, PACGA, PACDA, PACDB, PACDZA, PACDZB, PACIA,
PACIA1716, PACIASP, PACIAZ, PACIB, PACIB1716, PACIBSP, PACIBZ, PACIZA, PACIZB.
RETAA, RETAB, BRAA, BRAB, BLRAA, BLRAB, BRAAZ, BRABZ, BLRAAZ, BLRABZ.
